Ledipasvir-Sofosbuvir (Harvoni™) for Chronic Hepatitis C Infection Information for Prescribers / Healthcare Providers Ledipasvir-sofosbuvir (Harvoni™) for chronic hepatitis C infection genotype 1 and sofosbuvir (Sovaldi®) for chronic hepatitis C infection genotypes 1, 2 and 3 Ledipasvir-sofosbuvir (Harvoni™) and sofosbuvir (Sovaldi®) are direct-acting antivirals (DAA) for the treatment of hepatitis C virus (HCV) infection. Both drugs were reviewed by the Common Drug Review (CDR) followed by the review through the B.C. drug review process and the Pan-Canadian Pharmaceutical Alliance. B.C. drug reviews are based on many considerations, including available clinical and pharmacoeconomic evidence; input from specialists; input from patients, caregivers, and patient groups gathered through the PharmaCare Your Voice web page and the recommendations of an independent advisory body called the Drug Benefit Council (the Council). See www.cadth.ca/en/products/cdr for the CDR recommendations. Effective March 24, 2015, both drugs will be PharmaCare Limited Coverage benefits, through the Special Authority process, for patients who meet the specified criteria for the treatment of chronic HCV infection. PharmaCare coverage is currently available only to patients with liver fibrosis stage F2 or greater (Metavir scale or equivalent). This coverage approach is consistent with existing PharmaCare criteria for coverage of HCV therapies that provides coverage for patients at highest risk of liver-related morbidity.1 Further, this approach is also consistent with the CDR recommendations, may be more cost-effective and balances the need for sustainability of the PharmaCare program. For more information, see “Determining fibrosis stage for the treatment of chronic hepatitis” at www.health.gov.bc.ca/pharmacare/sa/criteria/restricted/pdf/fibrosis-info-sheet.pdf. Genotype 1 Ledipasvir-sofosbuvir (HarvoniTM) Ledipasvir-sofosbuvir (Harvoni™) is an interferon-free regimen indicated for treatment of genotype 1 (GT1) HCV infection. Ledipasvir-sofosbuvir has reported high cure rates (based upon sustained viral response), is dosed once-daily, is generally well-tolerated (compared to interferon-containing regimens) and offers a shorter duration of therapy for most patients. Therefore, ledipasvir-sofosbuvir is preferable to other therapies that PharmaCare currently covers for treatment-naïve and treatment-experienced GT1 patients. In clinical trials, ledipasvir-sofosbuvir reported high sustained viral response (SVR), ranging from 93-99% in treatment- naïve and -experienced GT1 patients.2-3 In treatment-naïve, non-cirrhotic patients, there is the option of utilizing a shorter 8-week course of therapy if the baseline HCV RNA is < 6 million IU/mL.3 In patients with an initial HCV RNA of > 6 million IU/mL a 12-week regimen is optimal, as shorter durations are associated with a higher relapse rate.3 Both treatment-naïve patients with compensated cirrhosis and treatment-experienced patients without cirrhosis reported high SVRs after 12 weeks with ledipasvir-sofosbuvir.2,4 In patients with compensated cirrhosis who are treatment- experienced (with either pegylated interferon and ribavirin (PegIFN/RBV) or in combination with a protease inhibitor), a 24-week regimen of ledipasvir-sofosbuvir is reasonable.4 Special Authority requests for coverage of 24 weeks of ledipasvir- sofosbuvir will be considered only for patients who have had a liver biopsy or transient elastography (TE) showing evidence of cirrhosis. Based on the recommendation from the CDR’s Canadian Drug Expert Committee (CDEC), ledipasvir-sofosbuvir is cost-effective compared to other therapies in treatment-naïve patients and treatment-experienced patients without cirrhosis. Medical Beneficiary and Pharmaceutical Services Division | Ministry of Health |March 2015 Sofosbuvir (Sovaldi®) in combination with peginterferon and ribavirin Sofosbuvir (Sovaldi®) in combination with PegIFN/RBV is eligible for PharmaCare coverage for GT1 treatment-naïve patients. However, due to lower tolerability with interferon regimens, sofosbuvir-ledipasvir is the preferred treatment option for GT1 patients. Genotype 2 or 3 Sofosbuvir (Sovaldi®) in combination with ribavirin PharmaCare coverage of sofosbuvir in combination with RBV is available for the treatment of genotype 2 (GT2) and 3 (GT3) HCV infections in patients who are: • treatment-naïve and have a medical contraindication to interferon therapy; or • PegIFN/RBV treatment-experienced. Genotype 2—Sofosbuvir in combination with RBV has not been shown to be more effective than the standard treatment with PegINF/RBV for treatment-naïve patients.6 In the sofosbuvir phase III trial (FISSION), sofosbuvir in combination with RBV was shown not to be inferior to PegIFN/RBV for treatment-naïve GT2 patients.5 GT2 responds well to PegIFN/RBV (SVR rates of 80-90%), similar to those found with sofosbuvir, which costs more.9-11 At manufacturer list prices, sofosbuvir costs $57,750 for 12 weeks of therapy whereas a 24-week or 48-week course of PegIFN/RBV costs $9,500 to $19,500. Therefore, sofosbuvir in combination with RBV offers no apparent clinical advantage with respect to SVR rates and is more costly than PegIFN/RBV in treatment-naïve patients.6 In those patients for whom interferon-based treatment is contraindicated or for those who are treatment-experienced, treatment with sofosbuvir and RBV for 12 weeks is reasonable as no other effective therapy options are available. In other trials (FUSION and VALENCE) sofosbuvir in combination with RBV achieved high rates of SVR for treatment-experienced GT2 patients with and without cirrhosis.7,8 Genotype 3—GT3 infections are less common and SVR rates achieves with standard therapy of PegIFN/RBV range from 62-77%.12-15 In the VALENCE trial, mixed population of treatment-naïve and -experienced patients receiving 24 weeks of sofosbuvir in combination with RBV therapy achieved an SVR of 85%.8 At manufacturer list prices, sofosbuvir costs $115,500 for 24 weeks of therapy whereas a 24-week or 48-week course of PegIFN/RBV costs $9,500 to $19,500. In those patients for whom interferon-based treatment is contraindicated—or for those who are treatment- experienced—24 weeks of treatment with sofosbuvir and RBV is reasonable, particularly as no other effective therapy options are available. Contraindications to Interferon Therapy for Genotype 2 or 3—PharmaCare covers sofosbuvir in combination with RBV for GT2 or GT3 treatment-naïve patients who, due to contraindications to IFN, cannot be treated with IFN-based therapy; or presence of significant clinical morbidities which are deemed to have a high risk of worsening with IFN treatment. • Contraindications to IFN are defined as:16 o Hypersensitivity reactions (urticarial, angioedeoma, bronchoconstriction, anaphylaxis, Stevens Johnson syndrome and toxic epidermal necrolysis) to peginterferon or interferon alfa-2a or -2b, polyethylene glycol, or any component of the formulation resulting in discontinuation of therapy o Autoimmune hepatitis o Decompensated liver disease • The presence of significant clinical comorbidities deemed at high risk of worsening with IFN treatment are considered relative contraindications. Significant clinical comorbidities include17-19: Neuropsychiatric Documented suicidal attempt or ideation; previous hospitalization for severe Documentation is required disorders depression; severe psychiatric, bipolar or schizoaffective disorder; history of of significant clinical homicidal ideation. comorbidities due to past Autoimmune Systemic lupus erythematosus, myositis, severe rheumatoid arthritis, severe medical history, including conditions psoriasis strategies to optimize Ischemic disorders Pre-existing cardiac abnormalities (e.g. cardiomyopathy, cardiac failure), unstable control.

Afdhal7 Elderly subjects have been historically underrepresented in clinical trials involving antiviral hepatitis C therapies. The aim of this analysis was to retrospectively evaluate the safety and efficacy of ledipasvir/sofosbuvir (LDV/SOF) by age groups of <65 years versus 65 years among subjects enrolled in phase 3 trials. Four open-label phase 3 clinical trials evaluated the safety and efficacy of LDV/SOF with or without ribavirin (RBV) for the treatment of genotype 1 chronic hepatitis C virus. Sustained virological response at 12 weeks, treatment-emergent adverse events (AEs), and graded laboratory abnor- malities were analyzed according to age group. Of the 2293 subjects enrolled in four phase 3 trials, 264 (12%) were 65 years of age, of whom 24 were aged 75 years. Sustained virological response at 12 weeks was achieved by 97% (1965/ 2029) of subjects aged <65 years and 98% (258/264) of subjects aged 65 years. The most common AEs in both LDV/ SOF groups that occurred in 10% of subjects were headache and fatigue. The rate of study discontinuation due to AEs was similar in the two age cohorts.

  • Hepatitis C Treatment
    Hepatitis C Treatment The goal of treatment for hepatitis C virus (HCV) is to cure the virus, which can be done with a combination of drugs. The specific meds used and the duration of treatment depend on a number of factors, including HCV genotype (genetic structure of the virus), viral load, past treatment experience, degree of liver damage, ability to tolerate the prescribed treatment, and whether the person is waiting for a liver transplant or is a transplant recipient. In some cases, HCV treatment may be limited by your health insurance plan or drug formulary. Here’s information about each type, or class, of approved HCV treatment along with drugs in the late stages of development: Multi-Class Combination Drugs Brand Name Generic Name Status Pharmaceutical Company Epclusa* sofosbuvir + velpatasvir Approved Gilead Sciences Harvoni* ledipasvir + sofosbuvir Approved Gilead Sciences Mavyret glecaprevir + pibrentasvir Approved AbbVie Vosevi sofosbuvir/velpatasvir/ Approved Gilead Sciences voxilaprevir Zepatier elbasvir + grazoprevir Approved Merck n/a daclatasvir + asunaprevir + Phase III Bristol-Myers Squibb beclabuvir *generic available What are they? Multi-class combination drugs are a combination of drugs formulated into a single pill or package of pills. For instance, the drug Harvoni combines two drugs, ledipasvir and sofosbuvir. Ledipasvir is an NS5A inhibitor and is only sold as part of Harvoni; sofosbuvir may be prescribed separately under the brand name of Sovaldi. Pegylated Interferon Alfa Brand Name Generic Name Status Pharmaceutical Company Pegasys peginterferon alfa-2a Approved Genentech What are they? Interferon is a protein made by the immune system, named because it interferes with viral reproduction. In addition, interferon signals the immune system to recognize and respond to microorganisms, including viral and bacterial infections.

  • Study Protocol and Statistical Analysis Plan
    Effects of Ledipasvir/Sofosbuvir on the Pharmacokinetics and Renal Safety of Tenofovir Alafenamide (TAF) NCT03126370 Protocol & Statistical Analysis Plan Version 03.29.2018 COMIRB Protocol COLORADO MULTIPLE INSTITUTIONAL REVIEW BOARD CAMPUS BOX F-490 TELEPHONE: 303-724-1055 Fax: 303-724-0990 Protocol #: 17-0490 Project Title: Effects of ledipasvir/sofosbuvir treatment on the pharmacokinetics and renal safety of tenofovir alafenamide (TAF) Principal Investigator: Jennifer J. Kiser, PharmD Version Number: 3.0 Version Date: 03/29/2018 I. Hypotheses and Specific Aims: Hypothesis: 1. Tenofovir plasma concentrations will be lower, tenofovir diphosphate concentrations in peripheral blood mononuclear cells will be higher, and tenofovir diphosphate concentrations in red blood cells (measured as dried blood spots, DBS) will be lower with tenofovir alafenamide relative to tenofovir disoproxil fumarate. 2. Tenofovir plasma and intracellular tenofovir diphosphate concentrations will increase when tenofovir alafenamide is co-administered with ledipasvir/sofosbuvir relative to TAF alone. 3. Markers of renal function (e.g. CrCl, urinary retinol binding protein/creatinine ratio and urinary beta-2 microglobulin/creatinine ratio) will not change when tenofovir alafenamide is coadministered with ledipasvir/sofosbuvir. Primary Aims: 1. Compare the area under the concentration time curve over the dosing interval (AUC0-24) of tenofovir in plasma when switched from tenofovir disoproxil fumarate (TDF) (Phase 1) to tenofovir alafenamide (TAF 25mg) (Phase 2), and compare the AUC0-24 of tenofovir in plasma given as TDF (Phase 1) to tenofovir in plasma in the form of TAF 25mg concomitantly with ledipasvir (LDV)/sofosbuvir (SOF) (Phase 3) 2. Compare TFV-DP in PBMCs between TDF (Phase 1) and TAF 25mg (Phase 2) and between TDF (Phase 1) and TAF 25mg plus LDV/SOF (Phase 3) Secondary Aims: 1.

Here we report that after screening 19 antiviral drugs that are either in clinical trials or with proposed activity against SARS-CoV-2, remdesivir was the most effective. Chloroquine only effectively protected virus-induced cytopathic effect at around 30 µM with a therapeutic index of 1.5. Our findings also show that velpatasvir, ledipasvir, litonavir, lopinavir, favilavir, sofosbuvir do not have direct antiviral effect. bioRxiv preprint doi: https://doi.org/10.1101/2020.04.29.067983; this version posted April 29, 2020.

  • Ledipasvir-Sofosbuvir (Harvoni)
    © Hepatitis C Online PDF created September 24, 2021, 10:29 pm Ledipasvir-Sofosbuvir (Harvoni) Table of Contents Ledipasvir-Sofosbuvir Harvoni Summary Drug Summary Adverse Effects Class and Mechanism Manufacturer for United States Indications Contraindications Dosing Clinical Use Cost and Medication Access Resistance Key Drug Interactions Full Prescribing Information Figures Drug Summary The fixed-dose combination of ledipasvir-sofosbuvir provides an effective and well-tolerated one-pill once-a- day option for treatment of genotypes 1, 4, 5, and 6 chronic hepatitis C (HCV) infection. This direct-acting antiviral regimen was the first FDA-approved interferon- and ribavirin free regimen to treat hepatitis C. Ledipasvir-sofosbuvir can be used without ribavirin in most patients with genotype 1A, except those who are cirrhotic and treatment-experienced. In addition, patients who are treatment-naïve, not black, and without cirrhosis may be eligible for an 8-week duration which has been found in clinical trials and observational studies to be as effective as 12 weeks. Like sofosbuvir-velpatasvir, the other NS5B-NS5A inhibitor combination, it has been shown to be safe and efficacious in patients with decompensated cirrhosis. Adverse Effects Available data from clinical trials has demonstrated the combination of ledipasvir-sofosbuvir has been very well tolerated. The most common reported adverse effects are fatigue and headache. Class and Mechanism Page 1/4 Ledipasvir is a potent inhibitor of HCV NS5A, a viral phosphoprotein that plays an important role in viral replication, assembly, and secretion. Sofosbuvir is a nucleotide analog inhibitor of hepatitis C virus NS5B polymerase—the key enzyme mediating HCV RNA replication.
