3 Executive Summary

Background: Multiple cytokine inhibitors are currently approved by the U.S. Food and Drug Administration (FDA) for the treatment of chronic, inflammatory, autoimmune conditions including plaque psoriasis (PsO), psoriatic arthritis (PsA), rheumatoid arthritis (RA), axial spondyloarthritis (ankylosing spondylitis [AS] and non-radiographic axial spondyloarthritis), juvenile idiopathic arthritis (JIA), Crohn’s disease (CD), and ulcerative colitis (UC). This report will review the cytokine inhibitors available as self-administered formulations (oral or subcutaneous). These include 11 interleukin (IL) antagonists (anakinra, brodalumab, canakinumab, guselkumab, ixekizumab, risankizumab-rzaa, sarilumab, secukinumab, tildrakizumab-asmn, tocilizumab, and ustekinumab), 4 tumor necrosis factor (TNF) alpha inhibitors (adalimumab, certolizumab pegol, etanercept, and golimumab), 3 janus kinase (JAK) inhibitors (baricitinb, tofacitinib, and upadacitinib), a T-cell co-stimulation modulator (abatacept), and a phosphodiesterase- 4 (PDE4) inhibitor (apremilast). Except for apremilast, baricitinib, tofacitinib, and upadacitinib, which are administered orally, the aforementioned agents are administered by subcutaneous injection, and of this subset, 4 can also be administered intravenously.

There are 2 main subclasses of cytokine modulators including biological therapies (TNF-alpha inhibitors, IL inhibitors, and a T-cell co-stimulation modulator) and the small molecule therapies (JAK inhibitors and a PDE4 inhibitor). The biologics are large, antibody-containing proteins that target extracellular immune signals. The small molecule drugs target signaling pathways inside immune cells. Cytokine inhibitors reduce inflammation and immune responses by directly inhibiting proinflammatory such as TNF alpha and specific (eg, IL-6, IL-12, and IL-23), targeting specific enzymes that are involved in cytokine-mediated signaling pathways (eg, JAK and PDE4), or blocking T-cell activation. The indication for some therapies is specific for patients who failed other traditional or conventional disease modifying agents such as methotrexate (MTX), hydroxychloroquine, leflunomide, and sulfasalazine. A few cytokine inhibitors have indications for patients who failed certain TNF inhibitors. Pharmacokinetic parameters differ among the cytokine modulators, with elimination half-lives ranging from 3 hours to 46 days. Dosage recommendations vary depending on the approved indication. Maintenance dosing frequency ranges from twice daily to every 12 weeks.

The aim of this report is to provide evidence from systematic reviews (SRs) and randomized controlled trials (RCTs) of head-to-head efficacy and safety comparisons among the cytokine inhibitors administered orally or subcutaneously for the treatment of PsO, PsA, RA, AS, JIA, CD, and UC. Other FDA- approved indications (eg, hidradenitis suppurativa, panuveitis, periodic fever syndromes, giant cell arteritis, or cytokine release syndrome) are outside the scope of this report.

Comparative Efficacy Evidence and Guideline Recommendations: Following a systematic literature search in Ovid-Medline and Embase for direct head-to-head comparisons among cytokine modulators, few comparative RCTs in psoriasis, psoriatic arthritis, and rheumatoid arthritis populations were identified. In the setting of ankylosing spondylitis, juvenile idiopathic arthritis, Crohn’s disease, and ulcerative colitis, there is an absence of direct head-to-head evidence. Listed below is a summary of the available direct comparative evidence by indication, together with guideline recommendations based on evidence review or expert opinion:

Plaque psoriasis: Three SRs (Sbidian 2017, No 2018, and Loos 2018) including a total of 11 head-to-head RCTs with cytokine inhibitors at FDA-approved dosages were identified. Information is only available for

4 certain comparisons in the adult population with moderate to severe PsO and multiple RCTs for the same comparison were rarely found. In terms of the proportion of patients achieving a 75% or 90% improvement in the Psoriasis Area and Severity Index (PASI 75 and PASI 90, respectively) at week 12 or 16, ustekinumab, secukinumab, ixekizumab, and tildrakizumab (interleukin inhibitors) were significantly more efficacious than etanercept (TNF inhibitor). Among interleukin inhibitors, secukinumab, brodalumab, and ixekinumab were significantly more efficacious than ustekinumab. Guselkumab (interleukin inhibitor) was significantly more efficacious than adalimumab (TNF inhibitor).

Regarding the 2019 Joint American Academy of Dermatology (AAD)/National Psoriasis Foundation (NPF) guideline for the treatment of psoriasis with biologics, etanercept, , adalimumab, ustekinumab, secukinumab, ixekizumab, brodalumab, guselkumab, tildrakizumab, and risankizumab are recommended as monotherapy for adults with moderate-to-severe plaque psoriasis, based on moderate- to high-quality evidence. Etanercept, infliximab, adalimumab, ustekinumab, secukinumab, and ixekizumab are recommended, based on high-quality evidence, as monotherapy for adults with psoriasis (any severity) associated with psoriatic arthritis. There are no specific recommendations for one biologic agent over another. In the pediatric population there was no head-to-head evidence identified. Only 2 biologic agents are FDA approved for plaque psoriasis in this population. Etanercept is approved for plaque psoriasis in children 4 to 17 years and ustekinumab is approved for plaque psoriasis in adolescents 12 to 17 years.

Psoriatic arthritis: Two SRs (Dressler 2019 and Corbett 2017) reported 4 head-to-head RCTs with cytokine modulators at FDA-approved dosages in patients with PsA. Two RCTs reported differences between cytokine inhibitors. One RCT (Atteno 2010) showed a significantly greater improvement of skin lesions (PASI responses) at year 1 with adalimumab compared to etanercept (at PsA dosage), but significantly better responses in terms of tender joint count and disability with etanercept compared to adalimumab. The other RCT (Langley 2014) included patients with PsO and reported subgroup data for patients with PsO and concomitant PsA. This trial did not evaluate psoriatic arthritis responses (eg, the American College of Rheumatology 20% improvement criteria); only PASI responses measuring the extension of psoriatic skin lesions were reported. There were significantly greater improvements in PASI responses with secukinumab compared to etanercept.

The 2018 American College of Rheumatology (ACR)/NPF guideline on psoriatic arthritis specifies the place in therapy for agents in treatment-naïve and treatment-experienced patients with active psoriatic arthritis; however, most treatment recommendations are based on very low- to low-quality evidence. For treatment-naïve patients, the use of TNF inhibitors is recommended over oral small molecules (OSM; eg, apremilast), an IL-17 inhibitor (secukinumab or ixekizumab), or an IL-12/23 inhibitor (ustekinumab). The use of IL-17 inhibitors is recommended over IL-12/23 inhibitors. For treatment- experienced patients (already treated with OSM or biologics), switching to a TNF inhibitor (or a different one) is recommended over other agents (eg, a different OSM, IL-17 inhibitor, IL-12/23 inhibitor, abatacept, or tofacitinib). Based on expert opinion, the European League Against Rheumatism (EULAR) recommends the use of TNF inhibitors over other biologics for the treatment of PsA. Overall, selection of therapy for the treatment of psoriatic arthritis should be individualized based on disease severity, contraindication to specific agents, patient preferences (oral versus injectable ), concerns about starting a biologic as the first therapy, convenience, and comorbidities (congestive heart failure, recurrent infections, demyelinating disease, inflammatory bowel disease, or diabetes).

5 Rheumatoid arthritis: Five SRs (Choy 2019, Venerito 2019, Ma 2019, Emery 2018, and Kawalec 2013) including head-to-head RCTs with cytokine inhibitors at FDA-approved dosages were identified. A meta- analysis (MA) of 2 RCTs in RA patients with inadequate response to DMARDs showed a significantly greater improvement in terms of the ACR 50% improvement criteria (ACR50 response) with tofacitinib 5 mg twice daily compared to adalimumab 40 mg every 2 weeks; but, no differences in ACR20 and ACR70 responses. One of the limitations of this MA is that the background therapy allowed in each RCT was different (monotherapy in one study vs. background methotrexate therapy in the other). The remaining 4 SRs reported 4 head-to-head RCTs. Only one RCT (Burmester et al) reported significant differences between treatments. Burmester et al included patients who could not receive MTX and showed significantly better results with sarilumab 200 mg every 2 weeks compared to adalimumab 40 mg every other week (both arms as monotherapies) in terms of rheumatoid arthritis activity, ACR 20/50/70 response rates, and disability. Nonetheless, this study did not assess a 40 mg weekly dosage of adalimumab, which is additionally approved for RA patients not receiving MTX. An additional RCT (identified in a secondary PubMed search) demonstrated superiority of upadacitinib compared to adalimumab for the ACR50 response, improvement in disease activity, reduction of pain, and improvement in physical function.

The 2015 American College of Rheumatology (ACR) guideline for RA provides recommendations based on disease duration, disease activity, and comorbidities. For patients with early RA (disease duration of less than 6 months) or established RA (disease duration ≥ 6 months) and moderate or high disease activity despite treatment with a conventional disease modifying antirheumatic drugs (cDMARDs) such as MTX, there is strong recommendation for the use of either a combination of cDMARDs, a TNF inhibitor, or a non-TNF biologic. Tofacitinib may be an additional option for patients with established RA. For patients with comorbidities, specific agents may be preferred (eg, use of a non-TNF biologic or tofacitinib over a TNF inhibitor for patients with congestive heart failure or use of abatacept over TNF inhibitors for patients with serious infections).

For populations with ankylosing spondylitis, juvenile idiopathic arthritis, or inflammatory bowel disease (CD or UC), direct head-to-head evidence is lacking. Guideline recommendations for these disease states are provided below:

Ankylosing spondylitis: The 2015 ACR guideline on AS and nonradiographic axial spondyloarthritis (SpA) recommends the use of TNF inhibitors in patients with active AS and an inadequate response or intolerance to at least 2 different NSAIDs over 1 or 2 months. No recommendations are specified for the IL-17 inhibitor because it was not available at the time of the 2015 ACR guideline publication. Due to the lack of head-to-head evidence, this guideline does not specify a preference for a TNF inhibitor over another in the overall population; however, infliximab or adalimumab are preferred over etanercept for patients with concomitant inflammatory bowel disease or recurrent iritis. Certolizumab pegol is the only biologic agent FDA-approved for non-radiographic axial spondyloarthritis.

Juvenile idiopathic arthritis: The 2019 American College of Rheumatology/Arthritis Foundation guideline for juvenile non-systemic polyarthritis, sacroiliitis, and enthesitis generally recommends biologic treatments (adalimumab, etanercept, golimumab, abatacept, or tocilizumab) in combination with a DMARD for certain children and adolescents with JIA and polyarthritis. TNF inhibitors are recommended for children and adolescents with JIA and active sacroilitis or enthesitis, despite having tried nonsteroidal anti-inflammatory drugs. This guideline does not specifically recommend one biologic over

6 another due to the lack of head-to-head comparisons. The 2013 ACR guideline for the treatment of systemic JIA has anakinra, canakinumab, tocilizumab, TNF-alpha inhibitors, and abatacept as treatment options.

Inflammatory Bowel Disease: Based on the American College of Gastroenterology (ACG) 2018 guideline for CD, biologics are recommended for the treatment of moderate-to-severe CD and for patients at high risk of disease progression. The anti-TNF agents (infliximab, adalimumab, and certolizumab pegol) and the IL-12/IL-23 inhibitor (ustekinumab) are considered for patients who have inadequately responded to conventional therapy with thiopurines, methotrexate, or corticosteroids. Adalimumab is additionally approved for adults with loss of response or inadequate response to infliximab, and ustekinumab is additionally approved and recommended for adults who have failed one or more anti-TNF inhibitor. Anti-TNF agents are also recommended for fistulizing and post-operative CD. The ACG notes that data is lacking to support switching patients during the maintenance of stable disease to a biosimilar product.

Options for induction of remission of moderately to severely active UC described in the 2019 ACG guideline include oral systemic corticosteroids; the anti-TNF agents, adalimumab, golimumab, or infliximab; the integrin inhibitor, ; and the JAK inhibitor, tofacitinib. For patients who failed anti-TNF therapy, vedolizumab or tofacitinib are recommended. If a biologic or tofacitinib is used for induction, it is recommended that the same agent be continued to maintain remission.

Safety: Only some head-to-head comparisons were evaluated with respect to safety outcomes and found mainly no differences as described in the Safety section of the report. The only significant safety difference reported among these studies was a higher incidence of local injection-site reactions leading to treatment discontinuation with adalimumab therapy versus abatacept.

Cytokine inhibitors may increase the risk of infections and, for most, product labeling warns about serious infections. Agents that have black box warnings pertaining to serious infection include the TNF- alpha blockers, JAK inhibitors, and the IL-antagonists, sarilumab and tocilizumab. Patients should be tested for (TB) infection prior to initiating cytokine inhibitors. TNF-alpha inhibitors, JAK inhibitors, and the IL-antagonists, sarilumab and tocilizumab, have black box warnings regarding TB infection. Labeling for TNF-alpha inhibitors warns of hepatitis B reactivation with treatment.

Hematological reactions (eg, leukopenia, pancytopenia, thrombocytopenia, aplastic anemia) may occur with the TNF-alpha inhibitors, JAK inhibitors, and with the IL-blockers, anakinra, sarilumab, and tocilizumab. Product labeling advises to avoid live vaccines for all the reviewed cytokine inhibitors with the exception of apremilast.

The development of anti-drug antibodies is possible with the biologic agents. In this situation, patients may require higher doses or lose response over time. Therapeutic drug monitoring and measurement of drug-antibodies may be used to determine the reason for inadequate response to biologic therapy.

Black box warnings are included for TNF-alpha inhibitors and JAK inhibitors regarding cases of malignancy. During controlled trials with the TNF-blockers, there were more cases of malignancies observed in the treatment arm compared to control. Cases of malignancy have also be reported with the use of utstekinumab and the JAK inhibitors.

There are thrombosis risk concerns with the JAK inhibitors. A black box warning for baricitinib and upadacitinib notes that thrombosis cases have been reported. The black box warning for tofacitinib is

7 specific to increased risk of mortality and thrombosis with the higher dosage of tofacitinib versus the lower dosage in RA patients 50 years or older with at least one cardiovascular risk factor. Some agents were associated with increased lipid parameters during clinical trials (sarilumab, tocilizumab, and the JAK inhibitors); yet, the effect of this elevation on cardiovascular risk has not been determined.

Brodalumab carries a black box warning concerning the risk of suicidal ideation and behavior with the use of this agent and is only available through a Risk Evaluation and Mitigation Strategy (REMS) program.

Summary: Evidence comparing cytokine inhibitors at FDA-approved dosages is available only for populations with plaque psoriasis, psoriatic arthritis, or rheumatoid arthritis, and is limited to only a few comparisons, mostly versus etanercept, adalimumab, or ustekinumab (see table 22 of this report). Head- to-head evidence is currently considered insufficient to guide clinical decision making.

Few significant differences among cytokine inhibitors have been demonstrated with respect to unique populations and short-term treatment. For RA patients, the following studies were identified: 1) a meta- analysis showed a significantly greater improvement in terms of ACR50 response with tofacitinib compared to adalimumab; but no differences in ACR20 and ACR70 responses, 2) a single RCT demonstrated superiority of upadacitinib compared to adalimumab (both in combination with MTX) in terms of ACR50 response, physical function, and pain reduction, and 3) a single RCT in patients unable to take MTX showed improved RA outcomes with sarilumab compared to adalimumab (both as monotherapy); however, authors compared only the every-other-week dosage of adalimumab but not the weekly dosing strategy. In terms of PASI 75 and 90 for adult patients with moderate to severe plaque psoriasis, ustekinumab, secukinumab, ixekizumab, and tildrakizumab were significantly more efficacious than etanercept; secukinumab, brodalumab, and ixekinumab were significantly more efficacious than ustekinumab; and guselkumab was significantly more efficacious than adalimumab. For psoriatic arthritis patients, an RCT showed a significantly greater improvement in PASI responses with adalimumab compared to etanercept (at PsA dosage), but significantly better responses in terms of tender joint count and disability with etanercept compared to adalimumab. Another RCT in PsA patients showed significantly greater improvements in PASI responses with secukinumab compared to etanercept.

The Utah Medicaid Preferred Drug List (PDL) includes, as preferred agents, 2 TNF-alpha inhibitors (Enbrel [etanercept] and Humira [adalimumab]) and an interleukin antagonist (Cosentyx [secukinumab]). Step therapy is required for Costenyx (ie, patients must fail another preferred agent first). Regarding the Medicaid fee-for-service (FFS) pharmacy data for 2018 through June 2019, Humira (adalimumab) and Enbrel (etanercept) are the most frequently utilized agents. For the purposes of the PDL, including at least 2 cytokine inhibitors may be considered. For those agents that are then listed as non-preferred, the panel may recommend the development of drug-specific prior authorization criteria designed to permit utilization for the rare disease-related approved indications.

8 Introduction The scope of this review encompasses the self-administered cytokine inhibitors that are FDA-approved for one or more of the following indications: rheumatoid arthritis (RA), spondyloarthritis (ankylosing spondylitis [AS] and non-radiographic axial spondyloarthritis), juvenile idiopathic arthritis (JIA), psoriatic arthritis (PsA), plaque psoriasis (PsO), and the inflammatory bowel disorders (IBD) of Crohn’s disease (CD) and ulcerative colitis (UC).1-20 A few of these conditions, JIA, AS, and pediatric IBD are rare diseases; thus some of the cytokine inhibitors have orphan designations. The more common disease states include RA, PsA, PsO, and IBD in the adult population. Table 1 summarizes the disease states for which self-administered cytokine inhibitors are approved. Detailed information regarding the full labeled indications is provided in upcoming sections of the report that are specific to each disease state. Several cytokine inhibitors reviewed are approved for other rare-diseases as shown in Table 2; however, these disease areas will not be a focus in our review (hidradenitis suppurativa, uveitis, periodic fever syndromes, giant cell arteritis, cytokine release syndrome, and Behcet’s disease).

Cytokine inhibitors work at various points along the inflammation response pathway to ultimately tone down an overly activated that is thought to contribute to disease progression. Most cytokine inhibitors are biologic agents that are large-molecule proteins (TNF inhibitors, interleukin inhibitors, and the selective T-cell costimulation modulator). Others are non-biologic agents that are small molecule proteins (Janus associated kinase [JAK] inhibitors and the phosphodiesterase 4 [PD4] inhibitor). The biologic agents are synthesized in cell lines and are administered as subcutaneous and/or intravenous injections. The small molecule drugs are available as oral formulations. Table 1 of Appendix A includes the available drug formulations for the cytokine inhibitors. Biosimilars are approved for both adalimumab and etanercept; yet, the market launch date of these agents has been delayed due to legal proceedings regarding patent exclusivity. Table 2 of Appendix A lists the brand names of approved biosimilar products that are currently unavailable.

The research objective of this report is to determine whether there are key efficacy or safety differences between the available cytokine modulators listed in Table 1, for their respective FDA-approved indications. The Utah Medicaid Preferred Drug List (PDL) groups these products under the category, Cytokine Modulators, Immunomodulators. Preferred products include an interleukin antagonist, Cosentyx (secukinumab), and 2 TNF-alpha inhibitors, Enbrel (etanercept) and Humira (adalimumab); step therapy is required for Costenyx (ie, patients must fail another preferred agent first).

Regarding the Medicaid fee-for-service (FFS) pharmacy data for 2018 through June 2019, utilization was highest for Humira (adalimumab) followed by Enbrel (etanercept) — PDL preferred status agents. Together these 2 agents made up 86% of the utilization and other cytokine inhibitors, altogether, made up 14% of the utilization from 2018 through June 2019. From the beginning of the year through June 2019, a total of 153 patients received a prescription for one of the reviewed cytokine inhibitors and of these, 13 were pediatric patients. Utilization in the pediatric FFS population (< 18 years) in 2019 included claims for Humira (adalimumab), Enbrel (etanercept), and Actemra (tocilizumab).

12 Methods Literature Search Search strategies were developed in OVID Medline and Embase. Strategies consisted of controlled vocabulary, such as Medical Subject Headings (MeSH), and keyword phrases. A methodological filter was used for SRs and meta-analyses (MAs). In Embase, we excluded conference abstracts. Authors conducted a grey literature search including the websites for the Oregon Drug Effectiveness Review Project (DERP) group and the Agency for Healthcare Research and Quality (AHRQ). Based on the literature searches described in the 2012 DERP report on targeted immune modulators,22 an updated search was carried out in Ovid Medline from January 2011 through June 7, 2019. Following the identification of high-quality SRs from the Ovid Medline results, Embase was then searched with specific date limits according to indication area already addressed in the identified SRs (from 2017 onward for CD and UC, from 2016 onward for PsO and PsA, and from 2011 onward for RA, AS, and JIA). The complete search strategies and terms are available in Appendix B. At the time of the literature search undertaking, upadacitinib was not yet approved so was not included in the search strategy. Following its approval in August, information for this medication was added based on the product labeling information and a non-systematic PubMed search (only using free text for the drug). Authors additionally screened the reference lists of related systematic reviews and other relevant websites for further information: 1. For guidelines addressing PsO, PsA, RA, JIA, AS, CD, and UC: websites of the American Academy of Dermatology, National Psoriasis Foundation, American College of Rheumatology, National Institute for Health and Care Excellence, American College of Gastroenterology, American Gastroenterological Association 2. For FDA-approved prescribing information: the US FDA website, Drugs@FDA: FDA Approved Drug Products 3. Evidence-based drug information databases: Micromedex, Lexicomp, and UpToDate Screening At least 2 review authors screened titles and abstracts. Conflicts were resolved via discussion between reviewers. The full texts for all citations receiving 2 inclusion votes were retrieved; inclusion was determined by the lead author. Figure 1 on page 56 shows the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) flow chart23 for the review process. Inclusion and Exclusion Criteria Systematic reviews of RCTs providing head-to-head efficacy or safety comparisons among the cytokine inhibitors listed in Table 1 were included. For product comparisons where a systematic review provided robust data, we examined additional systematic reviews published after the search date of the robust systematic review. Network meta-analyses (NMA) including standard pairwise meta-analyses of a cytokine inhibitor vs. another were included; however, the indirect- or mixed-treatment effect summary outcomes from the NMA were not included. Excluded references met the following criteria: 1) Review articles not using systematic review methodology, 2) Network meta-analyses including indirect comparisons only, or 3) SRs comparing cytokine inhibitors vs. placebo or conventional/traditional non-biologic DMARDs. A list containing the excluded references is provided in Appendix C.

13 Disease Overview and Guideline Recommendations There are many immune-mediated diseases characterized by inflammatory processes and abnormal immune system activity. These may include psoriasis, psoriatic arthritis, rheumatoid arthritis, ankylosing spondylitis, juvenile idiopathic arthritis, Crohn´s disease, and ulcerative colitis. Following there is information related to the disease states of interest for this drug class review as well as guideline recommendations. A. Psoriasis Psoriasis is a chronic, immune-mediated, inflammatory disease primarily characterized by skin and joint symptoms.24 Typical skin manifestations include “scaly, erythematous patches, papules, and plaques” that may cause pain, itch, burning sensation, and bleeding.24-26 These signs mainly appear on the scalp, trunk, buttocks, elbows, and knees.24 Psoriasis can cause visible disfiguration that usually affects the patient’s psychological quality of life.24,25 Epidemiology, Risk Factors, and Co-morbidities In 2013, approximately 7.4 million US adults (3.2% of US adults) had psoriasis.27,28 The estimated prevalence of psoriatic arthritis among patients with psoriasis ranges from 6% to 41%.29 Psoriasis is more common in adults compared to children.30,31 The exact cause of psoriasis is unknown; however, immune system, genetic, and environmental factors play an important role in the development of psoriasis.24,32 T helper cells (eg, IL-17A-secreting T helper cell) have been associated with psoriatic skin inflammation because they release cytokines that cause skin cell growth and redness due to angiogenesis in the psoriatic plaque.33,34 A family history of psoriasis has been identified in approximately 40% of people with psoriasis and psoriatic arthritis.33 Many immune-related genes have been strongly associated with psoriasis.24 Of them, PSORS1, a psoriasis-susceptibility locus on chromosome 6p21, is considered the major genetic risk factor for early-onset psoriasis.24,33 Other triggering factors associated with the development or exacerbation of psoriasis include trauma, obesity, infection (eg, Streptococcal infections), stress, (eg, beta-blockers, lithium, and some antibiotics), smoking, and alcohol consumption.26 Medical comorbidities commonly occurring in patients with psoriasis may include psoriatic arthritis, cardiovascular disease, metabolic syndrome, depression, anxiety, suicide, obesity, and inflammatory bowel syndrome.24,26 Classification of Psoriasis Psoriasis can be classified in different categories based on morphologic descriptions of skin lesions.24 However, based on clinical findings, patients can fall into more than 1 category.24 These major morphological categories include: 1) plaque psoriasis (also called psoriasis vulgaris), 2) inverse psoriasis (ie, intertriginous/flexural psoriasis), 3) erythrodermic psoriasis, 4) pustular psoriasis (eg, palmoplantar pustulosis and generalized pustular psoriasis), 5) guttate psoriasis, 6) nail psoriasis, and 7) psoriatic arthritis.24,26 Plaque psoriasis is the most common type of psoriasis, accounting for approximately 80% to 90% of cases.24,25 It is characterized by “monomorphic, sharply demarcated erythematous plaques covered by silvery lamellar scales” that can affect small parts of the body, large parts of the body, or the entire body surface (also called erythroderma, a potentially life-threatening complication of psoriasis).25 Frequent locations of plaque psoriasis are knee, elbows, scalp, peri-umbilical, perianal, and retro- auricular regions.25 The scalp is generally affected in 75% to 90% of the patients.25

14 Diagnosis Diagnosis of psoriasis is usually based on family history and physical examination of several body regions such as scalp, nails, and anogenital region.25,26,33 The patient’s new medication and infections should be evaluated for a potential contribution to psoriasis.25,33 Skin biopsy is rarely performed.25 Psoriasis Severity Severity of the psoriasis and efficacy of psoriasis treatment can be assessed with different rating scales such as the Psoriasis Area and Severity Index (PASI).24 PASI evaluates the severity (thickness, redness, and scaling) of skin lesions and extent of body surface area (BSA) affected.35 PASI score ranges from 0 (no disease) to 72 (maximal disease). This assessment tool is frequently used in clinical trials; however, it is rarely utilized in clinical practice.24,27 The percentage of BSA involved and Physician’s global assessment (PGA) are other frequently utilized assessment tools to evaluate psoriasis severity.24 PGA is an easier-to-use tool developed for clinical practice where the physician ranks 3 severity signs of psoriatic lesions (thickness, redness, and scaling) as cleared, minimal, mild, moderate, or severe.24-26 Impact of psoriasis on quality of life can be measured with several instruments such as the Short-Form 36 Health Survey (SF-36), Psoriasis Quality of Life (PQOL), or Dermatology Life Quality Index (DLQI).24,36 According to the severity of disease, psoriasis is commonly classified into 3 categories as mild, moderate, and severe or into 2 categories (for treatment purposes) as mild psoriasis (“limited” disease that is managed with topical therapies) and moderate to severe psoriasis (“extensive” disease that is managed with phototherapy or systemic therapy).37-39 Disease classification by severity is challenging due to the variety of objective features that should be considered (eg, severity of lesions, areas affected, extension of the area affected, and symptoms) and the subjective impact of psoriasis in each person.26,40 Specific definitions of disease severity vary in the literature; there are no formal definitions.29,40,41 The Medical Advisory Board of the NPF and the American Academy of Dermatology (AAD) propose definitions for the 3 disease categories based on the affected BSA, location of areas involved, and impact on quality of life.27,40 Overall, BSA measurement should not be used alone to evaluate the severity of psoriasis because there may be patients with small BSA affected who have severe psoriasis or patients with large BSA affected who have mild psoriasis.27,40 Table 3 includes definitions for mild, moderate, and severe psoriasis proposed by the NPF, the AAD, a European consensus, and the North American Psoriasis Guidelines. In addition, treatment options for each disease state are included. Treatment Strategies Psoriasis is a chronic disease with no cure; however, several treatment strategies are available to control symptoms and improve the patient’s quality of life,25 including topical agents (eg, anthralin, vitamin D derivatives, vitamin A derivatives, and topical steroids), phototherapy, systemic oral therapies (eg, acitretin, apremilast, cyclosporine, methotrexate, and systemic steroids), and injectable biologic agents (eg, the TNF-alpha inhibitors, certolizumab pegol, etanercept, adalimumab, and infliximab; the IL-12/23 inhibitors, ustekinumab; the IL-17 inhibitors, secukinumab, brodalumab, and ixekizumab; and the IL-23 inhibitors, guselkumab, risankizumab-rzaa, and tildrakizumab-asmn).31,42,43 Table 4 contains the FDA- approved indications and dosing recommendations for the self-administered cytokine inhibitors indicated for the treatment of plaque psoriasis.

Guideline Recommendations Evidence-based guidelines on psoriasis management have been developed by several professional organizations including the American Academy of Dermatology (AAD), National Institute for Health and Clinical Excellence, National Psoriasis Foundation (NPF), and Canadian Dermatology Association.

18 According to the American Academy of Dermatology guidelines, topical medications are recommended as first line options for mild-to-moderate plaque psoriasis (eg, corticosteroids, vitamin D analogues, tazarotene).24 Approximately 70% to 80% of patients experience mild to moderate psoriasis and are adequately treated with topical medication.25,47 Moderate to severe disease should be managed with phototherapy (ie, use of ultraviolet radiation) and/or systemic agents (traditional oral systemic agents or biologic agents).45 Topical medication can be added to phototherapy or systemic agents in patients with moderate to severe disease.26,48 Overall, treatment begins with topical therapy and if clinical goals are not met, can progress to phototherapy (as monotherapy or in combination), and then traditional systemic agents or biologic agents (as monotherapy or in combination).24 The 2019 Joint AAD-NPF guideline on biologic agents recommends 3 TNF-alpha inhibitors (adalimumab, etanercept, and infliximab) and 7 interleukin inhibitors (brodalumab, guselkumab, ixekizumab, risankizumab, secukinumab, tildrakizumab, and ustekinumab), as monotherapy, for moderate to severe plaque psoriasis in adult patients. For the treatment of psoriasis (any severity) and concomitant psoriatic arthritis in adults, etanercept, adalimumab, ustekinumab, secukinumab, and ixekizumab are strongly recommended. Specific recommendations for one biologic agent over another are not provided.27 Regarding certolizumab, no specific recommendations are given in this guideline. Apremilast is FDA approved for moderate to severe plaque psoriasis; however, it is not included in this guideline because it is a non-biologic agent.27 Joint AAD-NPF guidelines for the management of psoriasis with non-biologics are expected to be published in the first quarter of 2020.49 In the pediatric population, evidence for the treatment of psoriasis with biologic agents is limited. Only 2 biologic agents are FDA approved for plaque psoriasis in this population. Etanercept is approved for plaque psoriasis in children 4 to 17 years and ustekinumab is approved for plaque psoriasis in adolescents 12 to 17 years.27 Selection of therapy for psoriasis should be individualized based on disease presentation, extent of lesions, response to prior treatments, quality of life concerns, side effects, patient preferences, convenience, and comorbidities (eg, cardiovascular disease, metabolic syndrome, and psychological or psychiatric disorders).24,25,45 Table 5 and 6 summarize guideline recommendations for the treatment of psoriasis with cytokine inhibitors.

20 B. Psoriatic Arthritis Psoriatic arthritis (PsA) is a chronic inflammatory condition affecting joints and skin that may lead to disability and decreased quality of life. It is associated with psoriasis and typically characterized by peripheral arthritis, dactylitis, enthesitis, and spondylitis.53 The estimated prevalence of PsA is 1 to 2 per 1,000 in the overall population.53 According to the American College of Rheumatology/National Psoriasis Foundation (ACR/NPF), approximately 6 to 41% of patients with psoriasis develop PsA.53 The majority of patients with PsA (80-90%) experience nail lesions. Skin symptoms usually occur before the arthritis; however, some patients experience skin and joint symptoms at the same time and some experience arthritis first (10-15%). PsA is a heterogeneous disease that may affect ≤ 4 joints (asymmetric oligoarthritis) or ≥ 5 joints (symmetric polyarthritis). Some patients only experience distal interphalangeal joint damage. Others have axial disease together with peripheral arthritis. Early diagnosis and treatment is key to ameliorate long-term outcomes.53 Treatment options for psoriatic arthritis aim to reduce signs and symptoms, decrease disease activity, and achieve remission of disease.53 They can be broken up into nonpharmacological and pharmacological interventions. Nonpharmacological treatment includes physical therapy, occupational therapy, smoking cessation, weight loss, massage therapy, and exercise. Pharmacotherapies comprise symptomatic treatment for the acute management of symptoms (eg, nonsteroidal anti-inflammatory drugs [NSAIDs], systemic glucocorticoids, and local glucocorticoid injections) and immunomodulatory therapy for long-term management. Immunomodulatory agents include the following:53

• Oral small molecules (OSM): methotrexate, sulfasalazine, cyclosporine, leflunomide, and apremilast • TNF inhibitors: etanercept, infliximab, adalimumab, golimumab, and certolizumab pegol • IL-12/23 inhibitors: ustekinumab • IL-17 inhibitors: secukinumab, ixekizumab, and brodalumab • Cytotoxic T lymphocyte antigen (CTLA)4-immunoglobulin: abatacept • Janus kinase (JAK) inhibitors: tofacitinib Regarding the 2018 ACR/NPF guideline for the treatment of psoriatic arthritis, the panel of experts considered the following endpoints as clinically important when comparing therapies: 1) the American College of Rheumatology 20% response criteria (ACR20; primary composite endpoint mostly utilized in PsA clinical trials), 2) the Health Assessment Questionnaire disability index (HAQ-DI; a tool to assess physical functioning), 3) Psoriasis Area and Severity Index 75% response criteria (PASI 75; a measure of skin symptom improvements), and 4) serious infections.54 An ACR20 response represents an improvement of 20% or more in the number of tender and swollen joints, together with an improvement of 20% or more in at least 3 of the following 5 measures: patient’s global assessment of disease activity, patient´s assessment of pain, patient´s assessment of physical function, physician’s global assessment of disease activity, and the erythrocyte sedimendation rate or C-reactive protein (CRP) level.55 Table 7 contains the specific FDA-approved indications and dosing recommendations pertaining to the treatment of psoriatic arthritis for the self-administered cytokine inhibitors.

Guideline Recommendations Evidence-based guidelines on the management of psoriatic arthritis (PsA) have been developed by several professional organizations including the American College of Rheumatology (ACR), National Psoriasis Foundation (NPF), European League Against Rheumatism (EULAR), and American Academy of Dermatology (AAD).

The 2018 ACR/NPF guideline on PsA specifies the place in therapy for agents in treatment-naïve and treatment-experienced patients with active psoriatic arthritis; however, most preferences are based on very low to low-quality evidence. Active psoriatic arthritis is defined as “disease causing symptoms at an unacceptably bothersome level as reported by the patient, and judged by the examining clinician to be due to PsA based on ≥1 of the following: swollen joints, tender joints, dactylitis, enthesitis, axial disease, active skin and/or nail involvement, and extraarticular inflammatory manifestations such as uveitis or inflammatory bowel disease (IBD).”53

23 In patients treatment-naïve to oral small molecules (OSMs), TNF inhibitors, IL-17 inhibitors, or IL-12/23 inhibitors, low-quality evidence suggests the use of a TNF inhibitor (etanercept, infliximab, adalimumab, golimumab, or certolizumab pegol) over OSMs (methotrexate, sulfasalazine, cyclosporine, leflunomide, or apremilast) as first-line. OSMs may be used in specific situations (eg, patients without severe PsA and PsO, preference for oral therapy, or contraindication to TNF inhibitors). Based on very low-quality evidence (expert opinion), TNF inhibitors or OSMs are recommended over IL-17 inhibitors (eg, secukinumab and ixekizumab) or IL-12/23 inhibitors (ustekinumab). IL-17 or IL-12/23 inhibitors may be used over TNF inhibitors if severe psoriasis or a contraindication to TNF inhibitors exists. IL-17 or IL- 12/23 inhibitors may be used over OMSs if severe psoriasis or severe PsA. Based on very low-quality evidence (expert opinion), IL-17 inhibitors are recommended over IL-12/23 inhibitors, unless concomitant IBD or a preference for less frequent administration exists.53

In treatment-experienced patients, multiple switching options are provided. In OMS-experienced patients, low- to moderate-quality evidence suggests switching to a TNF inhibitor over a different OSM, IL-17 inhibitor, IL-12/23 inhibitor, abatacept, or tofacitinib. Based on low- to moderate-quality evidence, switching to IL-17 inhibitors over a different OSM, IL-12/23, abatacept, or tofacitinib is recommended. Based on low-quality evidence, switching to IL-12/23 inhibitors over a different OSM, abatacept, or tofacitinib is recommended. In TNF inhibitor-experienced patients, low to very low-quality evidence suggests switching to a different TNF inhibitor over IL-17 inhibitor, IL-12/23 inhibitor, abatacept, tofacitinib, or adding methotrexate. Switching to IL-17 inhibitors is preferred over switching to IL-12/23, abatacept, or tofacitinib. Switching to IL-12/23 inhibitors is preferred over abatacept or tofacitinib. In IL- 17 inhibitor-experienced patients, very low-quality evidence suggests switching to a TNF inhibitor over an IL-12/23 inhibitor, a different IL-17 inhibitor, or adding methotrexate. In IL-12/23 inhibitor- experienced patients, very low-quality evidence suggests switching to a TNF inhibitor over an IL-17 inhibitor or adding methotrexate. Alternative options may be considered in certain situations (eg, severe psoriasis, contraindication to TNF inhibitors, concomitant IBD, or a preference for oral therapy or less frequent subcutaneous administration).53

Evidence suggesting the efficacy of potential combination therapies of these drug categories versus monotherapy is limited and no strong recommendations are stated.53

The European League Against Rheumatism (EULAR) recommends the use of TNF inhibitors over other biologics for the treatment of psoriatic arthritis, based on expert opinion. Authors highlight the lack of consistent, supporting head-to-head data among biologics.56

Overall, selection of therapy for psoriatic arthritis should be individualized based on disease severity, contraindications, patient preferences (oral versus injectable medication), concerns about starting a biologic first-line, convenience, and comorbidities (congestive heart failure, recurrent infections, demyelinating disease, IBD, or diabetes).53 Table 8 summarizes guideline recommendations for cytokine inhibitors in the treatment of psoriatic arthritis.

27 C. Rheumatoid Arthritis Rheumatoid Arthritis (RA) is a systemic that causes inflammation and damage of the lining of joints in hands, wrists, and knees. RA also affects other organ tissues (eg, lungs, heart, and eyes), producing severe complications.59 The estimated number of American adults with RA is 1.3 million.60 Signs and symptoms of RA include joint pain, inflammation, stiffness, and tenderness, fever, fatigue, weight loss, and weakness. Diagnosis consists of symptom evaluation, physical examination, imaging (eg, X-ray or magnetic resonance imaging), and laboratory tests.59 According to the 2010 ACR and EULAR classification criteria, a patient is diagnosed with “definite RA” if there is “confirmed presence of synovitis in at least 1 joint, absence of an alternative diagnosis that better explains the synovitis, and achievement of a total score of 6 or greater (of a possible 10) from the individual scores in 4 domains: number and site of involved joints (score range 0–5), serologic abnormality (score range 0–3), elevated acute-phase response (score range 0–1), and symptom duration (2 levels; range 0–1).”61

The American College of Rheumatology classifies rheumatoid arthritis according to the duration of the disease or symptoms as early RA (less than 6 months) or established RA (6 months or longer).62 Disease activity is classified as low, moderate, or high based on validated scales such as patient activity scale (PAS), routine assessment of patient index data 3 (RAPID-3), clinical disease activity index (CDAI), and disease activity score 28 (DAS28). These scales can also be used to define disease remission.62 Common efficacy outcomes evaluated in clinical trials include the proportion of patients with at least 20%, 50%, or 70% improvement in the American College of Rheumatology criteria (ACR20, ACR50, or ACR70, respectively), disease activity score in 28 joints using the C-reactive protein level (DAS28-CRP), and Health Assessment Questionnaire–Disability Index (HAQ-DI). Radiographic damage progression, which correlates with disease activity, long-term disability, and efficacy of treatment, is occasionally evaluated.63

The goal of RA treatment is to improve signs, symptoms and physical function, achieve disease remission, and reduce disease activity and progression. Treatment approaches include agents to delay disease progression and prevent joint damage (ie, disease-modifying antirheumatic drugs [DMARDs]) and agents for symptom control such as non-steroidal anti-inflammatory drugs (NSAIDs). DMARDs indicated for RA include conventional synthetic DMARDs (methotrexate, hydroxychloroquine, sulfasalazine, and leflunomide), targeted biologic DMARDs (TNF inhibitors such as etanercept, adalimumab, certolizumab pegol, golimumab, and infliximab; abatacept, rituximab, and the interleukin inhibitors, anakinra, sarilumab, secukinumab, and tocilizumab), and targeted oral small molecule DMARDs (baricitinib, tofacitinib, and upadacitinib).62 Table 9 provides the labeled indications and dosing recommendations pertaining to the treatment of RA for the self-administered cytokine inhibitors.

Guideline Recommendations A wide variety of agents are available for the treatment of rheumatoid arthritis (RA). Guidelines recommend initiation of treatment as soon as RA is diagnosed. The 2015 American College of Rheumatology (ACR) guideline for RA provides recommendations based on disease duration, disease activity, and comorbidities. For patients with early RA or established RA and moderate or high disease activity despite treatment with a conventional disease modifying antirheumatic drugs (cDMARDs) such as methotrexate, it is strongly recommended the use of either a combination of cDMARDs, a TNF inhibitor, or a non-TNF biologic. Tofacitinib may be an additional option for patients with established RA. For patients with comorbidities, specific agents may be preferred (eg, use of a non-TNF biologic or tofacitinib over a TNF inhibitor for patients with congestive heart failure or use of abatacept over TNF inhibitors for patients with serious infections).62

32 D. Ankylosing Spondylitis Spondyloarthritis (SpA) includes several types of rheumatoid conditions characterized by inflammation and pain of different parts of the body (eg, back, extremities, entheses, and uvea).68-70 SpA is currently classified based on the clinical presentation as (1) axial SpA, if the spine, pelvis, and thoracic cage are predominantly affected or (2) peripheral SpA, if extremities are predominantly affected.57,71,72 Axial SpA is further classified into (1) non-radiographic axial SpA characterized by the absence of radiographic sacroiliitis (ie, inflammation of sacroiliac joints) and (2) radiographic axial SpA (also known as classic ankylosing spondylitis) characterized by the presence of radiographic variations in the sacroiliac joints.57,71-73 The estimated prevalence of axial SpA in adult Americans is between 0.9% and 1.4%.68 Ankylosing Spondylitis (AS) is the most common and widely studied type of SpA.69,74 It primarily affects the spine, particularly the sacroiliac joints;71,73,74 however, it can also affect other parts of the body such as shoulders, hips, ribs, hands, feet, eyes, bowel, heart, and lungs.75 Typical symptoms usually start in adolescence or early adulthood and include chronic back pain, inflammation, and stiffness.70,75 Disease progression may result in new bone formation and vertebral fusion, causing stiffness and loss of spinal mobility (ankylosis).70,71,74,75 The etiology of the disease is unknown. It is thought to relate to genetic factors. Around 70-90% of patients with either non-radiographic axial SpA or AS express the genetic marker, human leukocyte antigen B27 (HLAB27).71 Treatment strategies focus on relieving pain and stiffness, retaining spinal mobility, improving functional disability, reducing the risk of complications, and improving quality of life.76 Table 11 includes labeled indications and dosing recommendations for cytokine inhibitors FDA-approved for axial spondyloarthritis (ankylosing spondylitis and/or non-radiographic axial spondyloarthritis).

Guideline Recommendations

Evidence-based guidelines on the management of spondyloarthritis have been developed by several professional organizations including the American College of Rheumatology, the Assessments in Ankylosing Spondylitis International Society (ASAS), and the European League Against Rheumatism (EULAR). NSAIDs are the mainstay of pharmacological therapy for pain and stiffness relief in patients with AS.71,76 Biologic DMARDs such as the TNF inhibitors (adalimumab, certolizumab pegol, etanercept, and golimumab) or the IL-17A receptor inhibitor (secukinumab) are suggested as second-line therapy for AS.77 The 2015 ACR guideline on AS and nonradiographic axial SpA recommends the use of TNF inhibitors in patients with an inadequate response or intolerance to at least 2 different NSAIDs over 1 or 2 months.76 No recommendations are specified for the IL-17 inhibitor (secukinumab) because it was not available at the time of the 2015 ACR guideline publication. Due to the lack of head-to-head evidence, authors do not specify a preference for one TNF inhibitor over another in the overall population; 76 however, infliximab or adalimumab are preferred over etanercept for patients with concomitant inflammatory bowel disease or recurrent iritis. Certolizumab pegol is the only biologic agent FDA- approved for non-radiographic axial spondyloarthritis.16

The 2016 ASAS/EULAR guideline recommends the use of a TNF inhibitor over an IL-17 inhibitor for patients with persistently high disease activity who have not responded to conventional treatments. This recommendation is based on the volume and long-term efficacy and safety data available regarding the use of TNF inhibitors in axial SpA.77

Juvenile Idiopathic Arthritis Juvenile idiopathic arthritis (JIA), also called juvenile rheumatoid arthritis (JRA) or juvenile chronic arthritis (JCA), is one of the most frequently diagnosed form of childhood arthritis but overall is a rare disease.60,78,79 JIA is an umbrella term that includes all types of arthritis that start before the child is 16 years, last more than 6 weeks, and are of unknown origin.79-81 The estimated number of people in the US with juvenile arthritis is 294,000.60 Childhood arthritis may result in irreversible joint damage, disability, and reduced quality of life.78,80 Symptoms include joint pain, inflammation, fever, stiffness, rash, fatigue, loss of appetite, eye swelling, and difficulty in walking, playing, and dressing.78 According to the International League of Associations for Rheumatology (ILAR) classification criteria, there are 7 subtypes of JIA based on the number of joints affected, extraarticular manifestations (eg, uveitis), and markers such as rheumatoid factor (RF) and HLA-B27: (1) systemic arthritis, (2) oligoarthritis, (3) polyarthritis (RF negative), (4) polyarthritis (RF positive), (5) psoriatic arthritis, (6) enthesitis related arthritis, and (7) undifferentiated arthritis.81 Systemic JIA is defined by the ACR as “arthritis in ≥1 joint for at least 6 weeks' duration in a child age <16 years with or preceded by fever of at least 2 weeks' duration that is documented to be daily (“quotidian”) for at least 3 days and accompanied by one or more of the following: evanescent erythematous rash, generalized lymphadenopathy, hepatomegaly or splenomegaly, and serositis.”82 Polyarthritis (RF negative or positive) is defined as arthritis involving at least 5 joints during the first 6 months of disease.81 Diagnosis consists of symptom evaluation, physical examination, imaging (eg, X-ray or magnetic resonance imaging), and laboratory tests.39

The objective of pharmacological therapy in patients with JIA is to induce and preserve remission of symptoms, prevent irreversible joint damage, and improve the child´s quality of life.80 Treatment options are NSAIDs, oral and intraarticular glucocorticoids, non-biologic DMARDs, and biologic DMARDs.80 Five biologic DMARDs are currently available in the US for the treatment of JIA, including a T-cell costimulation modulator (abatacept), 2 TNF-alpha inhibitors (adalimumab and etanercept), and 2 interleukin inhibitors (canakinumab and tocilizumab). Abatacept, adalimumab, and etanercept are only approved for polyarticular JIA. Canakinumab is only approved for systemic JIA. Tocilizumab is approved for both polyarticular and systemic JIA. Table 13 includes labeled indications and dosing recommendations for the biologic agents FDA-approved for JIA.

Guideline Recommendations

The 2019 American College of Rheumatology/Arthritis Foundation guideline for juvenile non-systemic polyarthritis, sacroiliitis, and enthesitis generally recommends biologic treatments (adalimumab, etanercept, golimumab, abatacept, or tocilizumab) in combination with a DMARD for certain children and adolescents with JIA and polyarthritis.80 Initial therapy with biologics in JIA and polyarthritis may be considered for “patients with risk factors and involvement of high-risk joints (eg, cervical spine, wrist, or hip), high disease activity, and/or those judged by their physician to be at high risk of disabling joint damage.”80 TNF inhibitors are recommended for children and adolescents with JIA and active sacroilitis or enthesitis, despite having tried nonsteroidal anti-inflammatory drugs.80 This guideline does not specifically recommend one biologic agent over another due to the lack of head-to-head comparisons.80 The 2013 ACR guideline for the treatment of systemic JIA has anakinra, canakinumab, tocilizumab, TNF- alpha inhibitors, and abatacept as treatment options.82

38 F. Inflammatory Bowel Disease Inflammatory bowel disease (IBD) encompasses Crohn’s disease and ulcerative colitis which are idiopathic, chronic, immune-mediated inflammatory disorders. While the precise etiology is not fully understood, it is thought to involve genetic, immunologic, and environmental factors.85,86 The Centers for Disease Control and Prevention estimated from a national household survey (2015 National Health Interview Survey) that 3.1 million of US adults (1.3%) are diagnosed with IBD.3 About a quarter of IBD patients are diagnosed before adulthood and the natural history of pediatric disease is typically more severe compared to cases diagnosed later in life.87 Features that distinguish CD from UC include inflammation that may permeate all layers or thickness of the bowel wall (ie, transmural), discontinuous appearance (ie, skip areas), and deep linear serpiginous ulcers of the colon, strictures, fistulas, or granulomas.85 UC is “…usually confined to the mucosa,” most often involving the rectum.88

IBD is a relapsing disease with periods of exacerbation that dramatically reduce patient quality of life.88 Assessment and management of stress, depression, and anxiety—which are common in IBD— should be included in the comprehensive treatment approach to improve health-related quality of life and prescription adherence.85,86 While there are a variety of medications available for the treatment of IBD, the disease is not curable despite maintenance of remission or surgical intervention.

Biologics are generally used to induce and maintain clinical remission of moderately to severely active or high risk IBD and are thought to exert their effect on the entire gastrointestinal (GI) tract. There are 8 cytokine inhibitors FDA-approved for the treatment of IBD. Four are available as subcutaneous (SQ) injectable products (adalimumab, certolizumab pegol, golimumab, and ustekinumab) and 1 as an oral (PO) formulation (tofacitinib). Three cytokine inhibitors for IBD are intravenous products: infliximab (an anti-TNF agent indicated for CD and UC), and the integrin/adhesion inhibitors (indicated for CD) and vedolizumab (indicated for CD and UC).

Table 15 details the IBD indications of the SQ and PO administered cytokine inhibitors. Adalimumab is approved for both CD and UC; whereas, the other products are approved for only one IBD subtype (cetolizumab and ustekinumab for CD; and golimumab and tofacitinib for UC). Adalimumab has a pediatric indication for CD (patients ≥6 years old); others are only indicated for adults. With the exception of certolizumab, each product is approved for induction and maintenance of remission respective to the IBD-subtype indication. Certolizumab is approved for maintenance of remission (not induction)89 for moderately to severely active CD non-responsive to conventional therapy.

If response to therapy is inadequate, dose adjustments or a change of medication must be made. Therapeutic drug monitoring and measurement of drug-antibodies may be used to determine the reason for inadequate response to biologic therapy (particularly in UC). The body may produce antibodies to an employed monoclonal antibody drug that hastens the drug’s elimination. When drug efficacy is diminished because of this mechanism, it is called immune-mediated failure (ie, patients have high levels of drug-antibodies present and subtherapeutic drug levels). Non-immune-mediated drug failure may occur due to rapid drug clearance during high inflammatory burden (ie, patients lack drug- antibodies but have subtherapeutic drug levels). Mechanistic failure is when patients have therapeutic drug levels with no drug-antibodies; these patients must be switched to a drug with different mechanism of action (eg, patient on anti-TNF therapy may switch to an anti-interleukin 12/23 therapy or anti-integrin agent).

F.1 Crohn’s Disease Crohn's disease is most often destructive of the lower GI-tract, but not confined to this location as it may emerge anywhere from the mouth to the anus.6,85,90 Patients usually experience chronic diarrhea, fatigue, and abdominal pain usually in the lower right quadrant that may worsen after eating.85 Weight loss, fever, reduced bone mass, and linear growth in children can occur. Intra-intestinal manifestations include recurrent fistulas, strictures, and abscesses. The integrity and function of the intestine becomes compromised causing vitamin and mineral deficiencies. Extra-intestinal manifestations are numerous: those considered classic are arthropathy and dermatological, ocular, and hepatobiliary abnormalities (eg, , erythema nodosum, uveitis, scleritis, sclerosing cholangitis). Other complications may involve clotting disorders, metabolic bone diseases, and nephrolithiasis. Those with proximal GI, ileal, or ilealcolonic disease are at higher risk of intestinal complications than those with disease isolated to the colon. The cumulative 10-year risk of the need for a major abdominal surgery in Crohn’s disease is about 30%.85

CD is diagnosed using a combination of endoscopy, biopsy, and imaging studies, while taking into account signs/symptoms of gut inflammatory markers (eg, fecal calprotectin) and ruling out fecal pathogens.85 Once CD diagnosis is established, the patient’s disease burden is assessed to discern low or high risk of disease progression and the severity of disease activity. The determination relies on the provider’s overall impression without strict definitions for classifying patients. Table 1685,91 includes descriptions provided from treatment guidelines regarding the patient’s disease status or classification.

Authors of the 2018 American College of Gastroenterology (ACG) guideline for adult CD describe that their recommendations should be interpreted with flexibility. By providing a recommended option, this does not mean it is only acceptable treatment approach.85 The choice of therapy should be guided by patient preferences and depends on the disease location, disease activity, and severity of disease (ie, complications and prognosis). Goals of therapy include controlling disease flare within 3 months, maintaining control thereafter, and ultimately preventing further tissue damage (stricture and fistulas) or need for surgical intervention. Response to pharmacotherapy should be objectively evaluated by endoscopic or cross-sectional imaging; onset of clinical improvement and maximal improvement is expected within 2–4 weeks and 12–16 weeks, respectively.85 Biologics are employed for the treatment of moderate-to-severe CD and for patients at high risk of disease progression.85 Based on the ACG 2018 guideline, the anti-TNF agents (infliximab, adalimumab, and certolizumab pegol) and interleukin-12 and -23 (IL-12/IL-23) inhibitor, ustekinumab, are considered for patients who have inadequately responded to conventional therapy with thiopurines, methotrexate, or corticosteroids. Adalimumab is additionally approved for adults with lost or inadequate response to infliximab,15 and ustekinumab is additionally approved and recommended for adults who have failed one or more anti-TNF inhibitor.85,92 Other IV agents (natalizumab and vedolizumab) are also recommended for induction therapy. For maintenance of luminal disease, when an anti-TNF agent is used to induce remission, the anti-TNF agent should be continued for maintenance of remission; the addition of a thiopurine or methotrexate should be considered to reduce immunogenicity. Similarly, ustekinumab should be continued for maintenance of remission of ustekinumab-induced response. TNF-inhibitors may be added to a thiopurine or MTX for patients dependent on corticosteroids. Anti-TNF agents are also recommended for fistulizing and post-operative CD.85 The ACG notes that biosimilars of infliximab and adalimumab are

42 effective in moderate to severe CD for induction and maintenance therapy; however, data is lacking to support switching patients during the maintenance of stable disease to the biosimilar product. Table 1785,89,93 summarizes the 2018 ACG treatment recommendations regarding the biological therapies for CD in addition to those by the 2013 American Gastroenterology Association guideline and the 2019 guidance by a Canadian expert consensus panel.

F.2 Ulcerative Colitis Ulcerative colitis affects the large intestine, most often involving the rectum in adults. Symptoms include bleeding, urgency, and tenesmus (a sense of pressure). Complications include dysplasia and colorectal cancer thought to result from long-standing inflammation. Goals of therapy include maintaining steroid-

45 free remission, improvement in quality of life, and prevention of hospitalization, surgery, and cancer. Classification of disease severity is based on patient-reported bleeding and bowel habits, inflammatory burden per endoscopic assessment and markers of inflammation, disease course, and disease impact on daily function and quality of life. The greater number of poor prognostic factors, the greater likelihood of colectomy: age <40 at diagnosis, extensive colitis, severe endoscopic disease (Mayo endoscopic subscore 3 or Ulcerative Colitis Endoscopic Index of Severity ≥7), elevated C-reactive protein, low serum albumin.86

Options for induction of remission of moderately to severely active UC described in the 2019 ACG guideline for UC include oral systemic corticosteroids; the anti-TNF agents including adalimumab, golimumab, or infliximab; the integrin inhibitor vedolizumab; and the JAK inhibitor, tofacitinib. For patients who failed anti-TNF therapy, vedolizumab or tofacitinib are recommended for induction of remission. If a biologic or tofacitinib is used for induction, it is recommended that the same agent be continued to maintain remission. Patients with mildly active disease who are at a high risk of hospitalization or surgery may also be treated with the medications appropriate for moderately to severely active disease. Table 1886,94 summarizes the 2019 ACG treatment recommendations regarding the cytokine inhibitors for UC in addition to guidance outlined by the American Gastroenterology Association and a Canadian expert consensus panel.

Pharmacology & Special Populations

A. Oral Cytokine Inhibitors Four cytokine inhibitors among the list of products reviewed are small molecule drugs that are administered orally: apremilast, baricitinib, tofacitinib, and upadacitinib. The phosphodiesterase 4 enzyme (PD4E) inhibitor, apremilast, increases intracellular cyclic adenosine monophosphate (cAMP).96 This is thought to decrease pro-inflammatory mediators and increase anti-inflammatory mediators (eg, IL-10) to ultimately help downregulate inflammation contributing to plaque psoriasis and psoriatic arthritis.97 Baricitinib, tofacitinib, and upadacitinib are janus associated kinase (JAK) inhibitors. Janus kinases interact with the intracellular portion of transmembrane cytokine receptors, activating a signaling pathway and regulating intracellular activity. JAK inhibitors impede phosphorylation of Signal Transducers and Activators of Transcription [STATs] in the pro-inflammatory signaling cascade normally activated by cytokines.98,99 The usual dosing frequency of apremilast is twice daily and the elimination half-life is 6 to 9 hours.96 Apremilast is primarily metabolized by CYP3A4, with minor contributions from CYP1A2 and CYP2A6. The drug is cleared via urine and feces. Dose adjustment for hepatic impairment is not necessary; however, the dose should be reduced to 30 mg once daily for persons with severe renal impairment.96 Baricitinib is administered daily, with a half-life of 12 hours.99 The drug is primarily (75%) cleared hepatically (via CYP3A4) and 20% eliminated in the urine. Use is not recommended in severe hepatic impairment or with a glomerular filtration rate <60 mL/min/1.73m2.99 The half-life of tofacitinib is 3 and 6 hours for the immediate- and extended-release formulations, respectively. The usual dosing frequency is twice daily for the IR tablet and once daily for the XR tablet.98 Clearance of the parent molecule is 70% via hepatic metabolism (CYP3A4 primarily and CYP2C19) and 30% by renal excretion. Dose reductions are recommended for patients receiving CYP2C19 and/or CYP3A4 inhibitors; in patients with moderate or severe renal impairment or moderate hepatic impairment; and patients with lymphopenia, neutropenia, or anemia. Use in severe hepatic impairment is not recommended.98

48 Upadacitinib is available as an extended-release product, dosed once daily with its half-life about 8 to 12 hours. Metabolism occurs mainly through CYP3A4 and to a lesser extent via CYP2D6. There are no dose adjustment recommendations for renal or hepatic impairment; however, it is advised not to use the medication in severe hepatic impairment. B. Monoclonal Antibody Cytokine Inhibitors, Injectables B.1. Selective T cell Co-stimulation Modulator Abatacept is a containing the extracellular domain of human cytotoxic T-lymphocyte associated antigen 4 (CTLA-4) linked to the modified Fc portion of immunoglobulin G1 (IgG1). 100 It inhibits the interaction of CD80 and CD86 with CD28 to downregulate the costimulatory signal that contributes to activation of T lymphocytes. T lymphocytes are involved in the pathogenesis of RA and PsA and elevated in synovium of RA and PsA patients. Decreases in the serum levels of interleukin-2 receptor (sIL-2R), interleukin-6 (IL-6), rheumatoid factor (RF), C-reactive protein (CRP), matrix metalloproteinase-3 (MMP3), and TNFα were observed in clinical trials with abatacept treatment. The maintenance SC dosing interval is once weekly and corresponding terminal half-life is about 2 weeks.100 B.2. TNF-alpha Blockers TNF is a pro-inflammatory cytokine that interacts with the p55 and p75 cell surface TNF receptors. Elevated levels of TNF are found in synovial fluid of patients with RA, JIA, PsA, and AS and in psoriatic plaques. TNF is involved in promotion of adhesion molecules responsible for leukocyte migration.15 Inhibitors of TNF induce the lysis of various immune cells by either activation of complement-dependent cytotoxicity (CDC) or antibody-dependent cellular cytotoxicity (ADCC; mediated by Fc receptors).101 Full length, bivalent IgG monoclonal antibodies include adalimumab and golimumab. Certolizumab is a monovalent Fab-antibody fragment attached to polyethylene glycol. Adalimumab, certolizumab, and golimumab selectively bind soluble and transmembrane forms of TNF-alpha, blocking its interaction with the cell surface TNF receptors. Etanercept contains a dimer of the p75 TNF (TNFR2) receptor that binds TNF-alpha (soluble and transmembrane forms) and TNF-beta (lymphotoxin), inhibiting the stimulation of cell surface TNF receptors.101,102 Half-lives of adalimumab, golimumab, and certolizumab are approximately 2 weeks; SQ administration intervals for maintenance dosing are once monthly for golimumab, every 4 weeks or every other week for certolizumab, and every other week for adalimumab.15-17 The half-life for etanercept is about 5 days and the maintenance SQ administration interval is once weekly.102 B.3. Interleukin Antagonists Interleukin (IL) antagonists are monoclonal antibodies produced by recombinant DNA technology.10 They inhibit the release and activity of proinflammatory cytokines and chemokines by blocking the action of specific interleukins (eg, IL-17 or IL-23) or inhibiting interleukin receptors (eg, IL-6 receptor).1- 6,11-13 Interleukin production is triggered by inflammatory stimuli.10 Abnormally elevated levels of specific ILs are identified in synovium and synovial fluid and psoriatic plaques of patients with RA, psoriasis, PsA, and AS, which may cause cartilage damage and inflammation.1,4,10 Table 19 describes the mechanism of action of each interleukin inhibitor.

49 Interleukin antagonists are administered by subcutaneous injection and include an IL-1β inhibitor (canakinumab), three IL-23 inhibitors (guselkumab, risankizumab, and tildrakizumab), two IL-17 A inhibitors (ixekinumab and secukinumab), and an IL-12 and IL-23 inhibitor (ustekinumab). The recommended maintenance dosing frequency is every 4 weeks for canakinumab, ixekinumab, and secukinumab (half-lives ranging from 13 days to 31 days), every 8 weeks for guselkumab (half-life of 15 to 18 days), every 8 to 12 weeks for ustekinumab (half-life of 15 to 46 days), and every 12 weeks for risankizumab and tildrakizumab (half-lives ranging from 23 to 28 days).2-6,11,14 antagonists include anakinra (IL-1 receptor antagonist), brodalumab (IL-17 receptor A inhibitor), sarilumab (IL-6 receptor inhibitor), and tocilizumab (IL-6 receptor inhibitor). The half-life of anakinra is around 6 hours and is administered daily. The recommended maintenance dosing frequency for brodalumab and sarilumab is every 2 weeks. The half-life for sarilumab is 8 to 10 days and 11 days for brodalumab. Tocilizumab is administered every week or every 3 weeks (maintenance dosing), with a half-life ranging from 5 to 14 days.1,10,12,13 The effect of interleukin inhibitors in patients with renal or hepatic impairment has not been studied, except for Anakinra. Anakinra is significantly excreted the kidney and dosage adjustments are required in patients with severe renal impairment or end stage renal disease.10

55 Direct Comparative Evidence for Cytokine Modulators

The literature search for systematic reviews yielded 2343 unique records, of which 11 SRs including head-to-head RCTs of cytokine modulators for the rheumatoid arthritis, psoriasis, and psoriatic arthritis populations met inclusion criteria for the qualitative synthesis. There were no direct comparative RCTs found for the cytokine inhibitors in populations with ankylosing spondylitis, juvenile idiopathic arthritis, Crohn’s disease, and ulcerative colitis. Figure 1 shows the PRISMA flow diagram for the review process of SRs.

The following 2 sections address the clinical evidence identified in the literature search. Section 1 contains a summary of the reported head-to-head RCTs among systematic reviews and Section 2 includes detailed information regarding the trials and the comparative outcomes (ie, key findings for comparative efficacy and safety).

56 Section 1. Overview of Key Findings from Head-to-Head Evidence For the management of moderate-to-severe plaque psoriasis in adults, 3 SRs (Sbidian 2017, No 2018, and Loos 2018) containing a total of 11 head-to-head RCTs with cytokine modulators at FDA-approved dosages were identified.104-106 In terms of the proportion of patients achieving a 75% or 90% improvement in the Psoriasis Area and Severity Index (PASI 75 and PASI 90, respectively), ustekinumab, secukinumab, ixekizumab, and tildrakizumab (interleukin inhibitors) were significantly more efficacious than etanercept (TNF inhibitor). Among interleukin inhibitors, secukinumab, brodalumab, and ixekinumab were significantly more efficacious than ustekinumab. Guselkumab was significantly more efficacious than adalimumab. For all the aforementioned comparisons, no differences in safety outcomes were reported. For the management of psoriatic arthritis or plaque psoriasis with concomitant psoriatic arthritis, 2 SRs (Dressler 2019 and Corbett 2017) reporting 4 head-to-head RCTs with cytokine modulators at FDA-approved dosages were identified.107,108 Studies measured skin improvements (PASI scores) and/or joint involvement (eg, American College of Rheumatology [ACR] improvement criteria). One low-quality RCT (Mease 2017) showed no differences between ixekizumab and adalimumab in terms of ACR 20% response criteria (ACR20). This study was not powered to assess equivalency or non- inferiority versus adalimumab. Another RCT (Atteno 2010) showed a significantly greater improvement of skin lesions (PASI responses) at year 1 with adalimumab compared to etanercept (at PsA dosage), but significantly better responses in terms of tender joint count and disability with etanercept compared to adalimumab. The remaining 2 RCTs in psoriasis (Langley 2014 and Thaçi 2015) included subgroup data for patients with PsO and concomitant PsA. These trials did not evaluate psoriatic arthritis responses (eg, ACR20); only responses pertaining to skin lesions (ie, PASI) were reported. Secukinumab induced significantly greater PASI responses compared to etanercept and there were no differences compared to ustekinumab. For the management of rheumatoid arthritis, 5 SRs (Choy 2019, Venerito 2019, Ma 2019, Emery 2018, and Kawalec 2013) reporting head-to-head RCTs with cytokine inhibitors at FDA-approved dosages were identified.109-113 A meta-analysis (MA) of 2 RCTs (Fleischmann 2012 and van Vollenhoven 2012) showed a significantly greater improvement in ACR50 at week 12 with tofacitinib 5 mg twice daily compared to adalimumab 40 mg every 2 weeks, but no differences in terms of ACR20 and ACR70 at week 12. One of the limitations of this MA is that the background therapy allowed in each study was different (monotherapy in one study and background methotrexate therapy in the other). The remaining 4 SRs reported 4 head-to-head RCTs (Burmester 2017, Fleischmann 2017, Weinblatt 2013, and Jobanputra 2012). Burmester et al included patients who could not receive methotrexate and showed significantly better results with sarilumab 200 mg every 2 weeks compared to adalimumab 40 mg every other week (both arms as monotherapies) in terms of rheumatoid arthritis activity and disability. Nonetheless, this study did not assess a 40 mg weekly dosage of adalimumab, which is additionally approved for RA patients without concomittant methotrexate. Fleischmann et al showed tofacitinib is non-inferior to adalimumab (both in combination with methotrexate) with respect to ACR50. Weinblatt et al support non-inferiority of abatacept vs. adalimumab (both in combination with methotrexate) in terms of ACR20 at year 1. Jobanputra et al support non-inferiority of adalimumab vs. etanercept with respect to the percentage of patients continuing therapy over 52 weeks.

57 An additional RCT (Fleischmann 2019) was identified from the secondary PubMed search. This trial included RA patients with inadequate response to methotrexate and reported significantly greater improvements in terms of ACR50, physical function, and pain reduction at week 12; and significantly more patients achieving low disease activity or remission at week 26 with upadacitinib 15 mg daily compared to adalimumab 40 mg every other week (both in combination with methotrexate).114 For the management of ankylosing spondylitis, juvenile idiopathic arthritis, Crohn’s disease, or ulcerative colitis, no SRs reporting head-to-head RCTs were found. Table 22 includes the head-to-head studies reported in SRs. Most studies compared cytokine inhibitors at FDA-approved dosing. Some trials (eg, Langley 2014, Griffiths 2015, and Reich 2017) included patients receiving FDA and non-FDA approved dosages. The most common active comparators were the TNF inhibitors adalimumab and etanercept, and the interleukin inhibitor, ustekinumab. The following section describes these studies in further detail and Appendix D includes a table of key findings reported in the SRs.

60 Section 2. Detailed Information Regarding Head-to-Head Evidence A. Plaque Psoriasis Three SRs evaluated the comparative efficacy and safety among cytokine modulators in patients with moderate to severe plaque psoriasis. Sbidian el al106 (2017) performed a Cochrane review to assess the comparative efficacy and safety among systemic cytokine modulators for the treatment of moderate to severe plaque psoriasis or psoriatic arthritis in adults. This systematic review included pair-wise meta-analyses and network meta-analyses of RCTs. Primary outcomes were the proportion of patients achieving a 90% improvement in the Psoriasis Area and Severity Index (PASI 90) and the proportion of patients with serious adverse events (SAEs). Secondary endpoints included PASI 75, the proportion of patients with cleared or minimal disease according to the physician´s global assessment (PGA 0/1), and quality of life. Twelve head-to-head RCTs were identified. Results are described as follows: • In terms of PASI 90 response at week 12 (end of induction phase), direct head-to-head studies showed ustekinumab, secukinumab, and ixekizumab were significantly more efficacious than etanercept. Secukinumab and brodalumab were significantly more efficacious than ustekinumab at weeks 16 and 12, respectively. Guselkumab was significantly more efficacious than adalimumab in 2 studies that compared FDA-approved dosages at week 16 and in the meta- analysis with 3 studies, one of which used non-approved dosages. Regarding PASI 75 and PGA 0/1 responses, results were consistent with the results for PASI 90. • When comparing etanercept to small molecule drugs (tofacitinib, apremilast), no significant differences were shown in the PASI 90 response.106 However, apremilast was compared to etanercept at non-FDA approved dosing (50 mg weekly). Tofacitinib is currently not approved for psoriasis. • Regarding the percentage of patients with SAEs, no significant differences were found when comparing ustekinumab, secukinumab, or ixekinumab versus etanercept; secukinumab or brodalumab vs. ustekinumab; guselkumab vs. adalimumab; or etanercept vs. tofacitinib or apremilast.106 No et al (2018) found 12 head-to-head RCTs (10 RCTs already identified by Sbidian 2017 and 2 phase II RCTs, re-SURFACE 2 and NCT02054481). Efficacy results from individual studies were consistent with the results reported by Sbidian 2017. No traditional meta-analyses were conducted.105 Results for the 2 phase II studies are as follows: • Re-SURFACE 2 (Reich 2017) compared subcutaneous tildrakizumab (100 mg or 200 mg) at week 0, 4, 12, and 16 weeks versus etanercept 50 mg (twice weekly for 12 weeks; then once weekly) for the treatment of plaque psoriasis. At week 12, a significantly greater proportion of patients achieved a 75%, 90%, and 100% improvement in psoriasis severity (PASI 75/90/100 response) with tildrakizumab (100 mg or 200 mg) compared with etanercept. The proportion of patients with cleared or minimal disease according to the physician´s global assessment (PGA 0/1) and Dermatology Life Quality Index (DLQI 0/1) was significantly higher with tildrakizumab 200 mg (non-FDA approved dose) versus etanercept at week 12; however, this statistical significance was not achieved with tildrakizumab 100 mg (FDA-approved dose) versus etanercept. Serious adverse events were low and comparable between treatment groups.105,125

61 • NCT02054481 phase II study (Papp 2017) compared risankizumab at non-approved doses (18 mg, 90 mg, or 180 mg) versus ustekinumab (45 mg or 90 mg, depending on weight) for the treatment of plaque psoriasis. Significantly greater improvements in psoriasis in terms of PASI 50/75/90/100 and PGA 0/1 were reported with risankizumab versus ustekinumab.105,126 Loos et al (2018) conducted an SR and network meta-analysis of immunomodulators for the treatment of patients with moderate to severe psoriasis.104 Eigth head-to-head RCTs were reported in this SR (7 RCTs already identified by Sbidian et al and one new RCT published in 2017- IXORA-S trial133). Efficacy results from individual studies were consistent with the results reported by Sbidian 2017. Results for IXORA-S trial are as follows: • IXORA-S trial (Reich 2017) showed superiority of ixekizumab at the FDA-approved dosage (160 mg starting dose, then 80 mg every 2 weeks for 12 weeks, then 80 mg every 4 weeks) compared to ustekinumab at the FDA-approved dosage (45 mg or 90 mg at weeks 0, 4, 16, 28 and 40) in terms of PASI 90 response at week 12. PASI 75, PASI 100, and static PGA responses at week 12 were significantly greater with ixekizumab compared to ustekinumab. Efficacy results at 12 weeks were maintained up to 24 weeks. No significant differences were reported regarding the overall incidence of adverse events.133 B. Psoriatic Arthritis Two SRs comparing cytokine inhibitors in patients with psoriatic arthritis were identified (Dressler 2019 and Corbett 2017). Dressler et al (2019) performed an SR concerning the efficacy and safety of systemic treatments for the treatment of psoriatic arthritis in adult patients. One head-to-head RCT (Mease 2017: SPIRIT-P1) evaluating ixekizumab versus adalimumab, both at FDA-approved dosages, was identified. Results indicated no differences between these agents in terms of the American College of Rheumatology 20% response criteria (ACR20), American College of Rheumatology 50% response criteria (ACR50), adverse events, and Health Assessment Questionnaire Disability Index (HAQ-DI) after 16-24 weeks.108 This trial was under-powered to assess equivalency or non-inferiority versus adalimumab, as the primary objective was superiority assessment versus placebo.127 Corbett et al (2017) identified 3 head-to-head RCTs in adult patients with active psoriatic arthritis: • Two RCTs included patients with psoriasis (Langley 2014 and Thaci 2015). Authors reported subgroup data regarding skin symptom response (ie, PASI) for those patients with concomitant PsA. In Langley 2014, secukinumab had significantly better PASI 75 and PASI 90 responses than etanercept at week 12. In Thaçi 2015, no significant differences were reported between secukinumab and ustekinumab with respect to PASI 90 at week 16. These 2 RCTs did not have data for joint symptom response in patients with PsA. • The third RCT (Atteno 2010) compared adalimumab and etanercept, both at approved dosages for PsA, and showed different results depending on the outcome measured. In terms of PASI, adalimumab had significantly better skin responses compared to etanercept; however, in terms of tender joint count and disability, etanercept had significantly better responses vs. adalimumab.128 Of note, etanercept was used at the approved dosage for psoriatic arthritis (50 mg weekly), a lower dosage than that approved for plaque psoriasis (50 mg twice weekly).

62 C. Rheumatoid Arthritis Five SRs providing head-to-head evidence in patients with active RA were identified (Choy 2019, Venerito 2019, Ma 2019, Emery 2018, and Kawalec 2013).109-113 Kawalec et al (2013) conducted a systematic review and meta-analysis of 2 RCTs (Fleischman 2012 and van Vollenhoven 2012) to compare the efficacy and safety of tofacitinib 5 mg twice daily versus adalimumab 40 mg once every 2 weeks. Regarding the percentage of patients achieving a 20% and 70% improvement response based on the ACR criteria (ACR20 and ACR70, respectively) at week 12, no significant differences were reported between both agents. With respect to the ACR50 response at week 12, tofacitinib was significantly better than adalimumab. No differences were reported between groups regarding the incidence of serious adverse events and discontinuations due to adverse events.113 One of the limitation of this meta-analysis is the use of different background therapy in each RCT. Based on data from Fleischman 2012 (patients on monotherapy), Kawalec et al reported no significant differences between agents with respect to ACR50 response. Based on data from van Vollenhoven 2012 (patients receiving methotrexate), Kawalec et al showed a significantly greater improvements with tofacitinib vs. adalimumab in terms of ACR50 response.113 Choy 2019, Venerito 2019, Ma 2019, and Emery 2018 reported 4 RCTs. Key findings for individual RCTs are described below: Fleischmann 2017 conducted a 1-year RCT to compare the efficacy and safety of tofacitinib 5 mg twice daily versus adalimumab 40 mg every other week (both in combination with methotrexate [MTX]). Tofacitinib plus MTX was non-inferior to adalimumab plus MTX in term of ACR50 responses at month 6. No differences were reported between groups regarding ACR20, ACR70, and the number of patients with low disease activity or remission.131 Burmester et al (2017) conducted a 24-week RCT (superiority trial – MONARHC study) to compare the efficacy and safety of sarilumab monotherapy (200 mg every 2 weeks) versus adalimumab monotherapy (40 mg every 2 weeks) in RA adult patients with intolerance or inadequate response to methotrexate. The primary efficacy endpoint was the change from baseline in the severity of RA measured by the Disease Activity Score-28 using erythrocyte sedimentation rate (DAS28-ESR) at week 24. Sarilumab showed superiority over adalimumab for the primary endpoint. Regarding secondary endpoints, sarilumab showed significantly better results compared to adalimumab in terms of ACR 20/50/70 response rates, Health Assessment Questionnaire Disability Index, Clinical Disease Activity Index remission, and low disease activity. Safety profiles of both agents were comparable, with similar rates of adverse events, serious adverse events, discontinuations between treatment groups.129 Although this study assessed differences with adalimumab dosed every other week, it is unknown how the treatments would compare if adalimumab was dosed at 40 mg weekly, an additional dosing frequency approved for RA patients not receiving methotrexate. Weinblatt et al (2013) conducted a 2-year, non-inferiority RCT (AMPLE study) to evaluate the efficacy and safety of subcutaneous abatacept (125 mg once weekly) plus MTX compared to subcutaneous adalimumab (40 mg every other week) plus MTX in patients with active RA who had inadequate response to methotrexate and had not received biologic therapy. This publication reports the results at year 1. Abatacept was non-inferior to adalimumab regarding ACR20 response at year 1.63 Regarding secondary efficacy endpoints, comparable results were reported between groups in terms of ACR50 response, ACR70 response, Disease Activity Score in 28 joints using the C- reactive protein level (DAS28-CRP) score, and radiographic damage progression. Similar safety

63 profiles between both agents were reported, except for the incidence of local injection-site reactions that was significantly higher with adalimumab therapy vs. abatacept and led to treatment discontinuation.63 Schiff et al (2014) published the final results of the 2-year AMPLE study.130 A non- inferiority evaluation for efficacy was not formally assessed at year 2, nor were safety outcomes statistically compared.130 At the end of year 2, ACR 20, ACR50, ACR70, and radiographic outcomes were similar between both treatment groups and compared to year 1 results. There were similar adverse events and serious adverse events between abatacept and adalimumab. Numerically more serious infections were reported with adalimumab compared to abatacept. Lower discontinuation rates due to adverse events (including serious adverse events and serious infections) and fewer injection site reactions were reported in the abatacept group compared to adalimumab. Jobanputra et al (2012) conducted an unblinded, pragmatic non-inferiority trial (RED SEA study) to compare subcutaneous adalimumab 40 mg every other week versus etanercept 50 mg weekly in RA patients with inadequate response to 2 DMARDs (eg, MTX).132 Adalimumab was non-inferior to etanercept with respect to the percentage of patients continuing therapy over 52 weeks. DAS28 response, treatment satisfaction, and adverse events (key secondary outcomes) were similar between groups after 52 weeks. Some limitations of this study include the absence of blinding, pragmatic design, and wide non-inferiority margin.132 An additional RCT (Taylor 2017) in adult patients with active RA was reported in the SR by Choy 2019. In this trial, patients received baricitinib 4 mg once daily, adalimumab 40 mg every other week, or placebo.134 Since baricitinib 4 mg is a non-FDA-approved dosage, we do not focus on results since the effects of the 4 mg can not be automatically extrapolated to the lower 2 mg approved dosage.134 At the time of the literature search undertaking, upadacitinib was not yet approved so was not included in the search strategy. Based on the product labeling information and a secondary search in PubMed after its approval in August, a head-to-head RCT was identified (Fleischmann 2019).114 This trial compared upadacitinib 15 mg once daily versus adalimumab 40 mg every other week (both in combination with MTX) in adults with RA and an inadequate response to MTX. Upadacitinib was superior to adalimumab regarding the ACR50 response rate, percentage of patients achieving a DAS28-CRP score of ≤3.2, pain reduction (as measured by the 0-100 mm visual analog scale), and improvement in physical function (as measure by HAQ-DI). A significantly higher number of patients on upadacitinib achieved low disease activity or remission compared to adalimumab.114 Adverse events and serious adverse events were similar between both agents, with the exception of a numerically higher incidence of herpes zoster and creatine phosphokinase elevations with upadacitinib.114

64 Safety Direct Comparative Evidence

A systematic review (Desai 2016) of 10 RCTs and 51 observational studies showed comparative safety results based on head-to-head studies with cytokine inhibitors in RA, PsO, and PsA population.135 With respect to overall adverse events and/or serious adverse events, 4 RCTs in 5 publications (Weinblatt 2013, Schiff 2014, Jobanputra 2012, van Vollenhoven, and Fleischmann 2012) including RA patients showed no significant differences for adalimumab versus abatacept, etanercept, or tofacitinib. Authors stated that the strength of evidence for these outcomes was low or insufficient. Two RCTs in PsO patients reported no significant differences in terms of overall adverse events and serious adverse events for etanercept versus ustekinumab. Regarding treatment discontinuation due to adverse events, no significant differences were observed among cytokine inhibitors; however, 1 RCT (Schiff 2014) in RA patients showed less risk of discontinuation due to adverse events with abatacept compared to adalimumab at FDA-approved dosages. Based on observational data, a lower risk for drug discontinuation due to AEs, serious infections, and tuberculosis was reported with etanercept compared to adalimumab in RA patients. With respect to the incidence of mortality, malignancies, and herpes zoster, evidence was insufficient to demonstrate any difference between adalimumab and etanercept in RA patients.135 In non-RA patients, comparative safety evidence was very limited.135

In the setting of plaque psoriasis, a Cochrane review (Sbidian et al) assessed safety outcomes and showed no significant differences in terms of serious adverse events (primary safety outcome) with ustekinumab, secukinumab, or ixekinumab versus etanercept; secukinumab or brodalumab vs. ustekinumab; and guselkumab vs. adalimumab.106 Similarly, Loos et al reported an RCT showing no significant differences regarding the overall incidence of adverse events between ixekizumab vs. ustekinumab.104

Regarding psoriatic arthritis, Dressler et al reported an RCT showing no differences in adverse events between ixekizumab versus adalimumab.108

In the setting of rheumatoid arthritis, a meta-analysis of 2 RCTs (Kawalec 2013) reported no differences between tofacitinib 5 mg and adalimumab 40 mg every 2 weeks regarding the incidence of serious adverse events and discontinuations due to adverse events.113 An RCT (Weinblatt et al) reported similar safety profiles between adalimumab and abatacept, except for the incidence of local injection-site reactions leading to treatment discontinuation, which was significantly higher with adalimumab therapy vs. abatacept.63 Another RCT (Fleischmann 2019) reported similar adverse events and serious adverse events between upadacitinib and adalimumab, with the exception of a numerically higher incidence of herpes zoster and creatine phosphokinase elevations with upadacitinib.114 Warnings and Precautions Immunogenicity

Biologic agents are efficacious in the treatment of autoimmune diseases such as RA, SpA, and IBD. However, some patients receiving biologics require higher doses or lose response over time due to the formation of antibodies against biologic agent. Anti-drug antibodies may reduce or inhibit the effect of the monoclonal antibody. When drug efficacy is diminished through this mechanism, it is called

65 immune-mediated failure. In this scenario, patients have elevated levels of drug-antibodies present and subtherapeutic drug levels. Therapeutic drug monitoring and measurement of drug-antibodies may be used to determine the reason for inadequate response to biologic therapy (particularly in UC).86 Infection Potential, Screening for Latent Infections, and Hematological Abnormalities

A main concern with immunosuppressive therapies is the increased risk of infection. Cytokine inhibitors may increase the risk of infections and most have warnings about risk of serious infections. Several agents have black box warnings pertaining to serious infection; this group includes TNF-alpha blockers, JAK inhibitors, and 2 IL-antagonists, sarilumab and tocilizumab.7,8,12,13,15-18,20 Patients should be tested for tuberculosis (TB) infection prior to initiating cytokine inhibitors. TNF-alpha inhibitors, JAK inhibitors, and the IL-antagonists, sarilumab and tocilizumab, have black box warnings regarding TB infection.7,8,12,13,15- 18,20 To minimize the risk for TB reactivation, positive cases of latent TB should be started on prophylaxis therapy before initiating treatment with a cytokine inhibitor. Cytokine inhibitors should not be started with active TB infection or any other serious infection. Labeling for TNF-alpha inhibitors warns of hepatitis B reactivation with treatment.15-18 Other possible infections should be considered according to clinical guideline recommendations before initiating treatment with these agents. For example, the ACG recommends screening for TB and viral hepatitis prior to initiating ant-TNF therapy in all CD patients and considering whether other latent opportunistic infections (eg, histoplasmosis and blastomycosis) are present based on patient risk factors.85

Hematological reactions (eg, leukopenia, pancytopenia, thrombocytopenia, aplastic anemia) may occur with the TNF-alpha inhibitors, JAK inhibitors, and with the IL-blockers, anakinra, sarilumab, and tocilizumab.7,8,10,13,15-18,20

Product labeling advises to avoid live vaccines for all the reviewed cytokine inhibitors with the exception of apremilast.1-20 Current CDC immunization schedules should be referred to for additional instructions regarding use of vaccines in patients with planned iatrogenic immunosuppression. Malignancies

Black box warnings are included for TNF-alpha inhibitors and JAK inhibitors regarding cases of malignancy.7,8,15-18,20 During controlled trials of the TNF-blockers, there were more cases of malignancies observed in the treatment arm compared to control. Cases of malignancy have also been reported with the use of utstekinumab and the JAK inhibitors. Cardiovascular Concerns Thrombosis cases (eg, deep venous thrombosis and pulmonary embolism) have been reported with the use of JAK inhibitors; this is a black box warning for baricitinib and upadacitinib.8,20 The black box warning for tofacitinib specifically refers to a higher incidence of thrombosis and all-cause mortality with the use of tofacitinib 10 mg twice daily compared to tofacitinib 5 mg twice daily or TNF inhibitors in RA patients 50 years and older with at least 1 cardiovascular risk factor.7 There are some uncertainties concerning the use of JAK inhibitors at higher doses and the association of a higher incidence of cardiovascular events. A 2019 SR and MA of RCTs comparing JAK inhibitors versus placebo for adult patients with RA showed no association between tofacitinib or baricitinib, individually, and cardiovascular events (all cardiovascular events, major cardiovascular events, and venous

66 thromboembolism events). When various JAK inhibitor doses were compared, no significant differences in cardiovascular safety were observed with tofacitinib 5 mg versus tofacitinib 10 mg; however, baricitinib 2 mg (the single FDA-approved dose) showed a significantly better cardiovascular safety profile compared to baricitinib 4 mg. Authors suggest that further post-marketing studies are needed to clarify the cardiovascular risk/benefit profile of these agents.136 Data from a large, ongoing postmarketing study in RA patients 50 years or older with at least one cardiovascular risk factor showed an increased risk of all-cause mortality, pulmonary embolism, deep venous thrombosis, and arterial thrombosis with tofacitinib 10 mg twice daily versus tofacitinib 5 mg twice daily or versus TNF inhibitors.7 Consequently, this year, the FDA included a black box warning for Xeljanz (tofacitinib) regarding this risk.7 8

Some agents were associated with increases in lipids (LDL, HDL cholesterol, or triglycerides) during clinical trials (sarilumab, tocilizumab, and the JAK inhibitors); yet, the effect of this elevation on cardiovascular risk has not been determined. Lipid levels should be monitored during treatment and elevations can be managed according to clinical guidelines as necessary. 7,8,12,13,20 Suicidal Ideation

Brodalumab carries a black box warning concerning the risk of suicidal ideation and behavior with the use of this agent.1 Four completed suicides were reported in psoriasis clinical trials with brodalumab. This medicine is only available through the Siliq Risk Evaluation and Mitigation Strategy (REMS) program.1

The warnings discussed thus far in addition to others are summarized in Tables 23, 24 and 25.
