Introduction

An antibody is a blood protein. When the immune system detects an unhealthy cell, antibodies link to a molecule, known as an , on the unhealthy cell. Monoclonal antibodies are produced in a laboratory. They are made to link to usually found in high numbers on cancer cells. Antibody-drug conjugates combine monoclonal antibodies with certain drugs. The monoclonal antibodies find the cancer cells and the chemotherapy drug is released directly into those cells. The goal with this treatment is to target only cancer cells and spare nearby healthy cells. This policy describes when specific antibody-drug conjugates may be considered medically necessary.

Note: The Introduction section is for your general knowledge and is not to be taken as policy coverage criteria. The rest of the policy uses specific words and concepts familiar to medical professionals. It is intended for providers. A provider can be a person, such as a doctor, nurse, psychologist, or dentist. A provider also can be a place where medical care is given, like a hospital, clinic, or lab. This policy informs them about when a service may be covered.

Evidence Review

Background

Mechanism of Action

Inotuzumab and gemtuzumab ozogamicin are antibody drug conjugates (ADCs) that are composed of 3 important components: the recombinant humanized immunoglobulin class G subtype 4 (IgG4) kappa antibody (being either inotuzumab or gemtuzumab), N-acetyl gamma- (or for short calicheamicin), and an acid-cleavable linker. Calicheamicin covalently binds to the through the linker. The complex mechanism begins when the ADC binds to receptors on CD22 (if inotuzumab) or CD33 (if gemtuzumab) expressing tumor cells and internalize forming an endosome. This complex fuses with lysosomes, leading to degradation of the acid labile linker and intracellular release of calicheamicin. Calicheamicin activation breaks double-stranded DNA, causing downstream effects such as cell cycle arrest and eventual cell apoptosis.

Loncastuximab tesirine-lpyl is a CD19-directed antibody and alkylating agent conjugate, consisting of a humanized IgG1 kappa monoclonal antibody conjugated to SG3199, a pyrrolobenzodiazepine (PBD) dimer cytotoxic alkylating agent, through a protease-cleavable valine-alanine linker. The monoclonal IgG1 kappa antibody component binds to human CD19, a transmembrane protein expressed on the surface of cells of B-lineage origin. Upon binding to CD19, loncastuximab tesirine-lpyl is internalized followed by release of SG3199 via proteolytic cleavage. The released SG3199 binds to the DNA minor groove and forms highly cytotoxic DNA interstrand crosslinks, subsequently inducing cell death.

Besponsa® (inotuzumab ozogamicin)

INO-VATE ALL

INO-VATE ALL was an open-label, two-group, randomized (1:1), phase III trial which assessed efficacy and safety of inotuzumab ozogamicin compared to standard intensive chemotherapy in adult patients with r/r ALL. Patients were randomized based on duration of first remission (<12 months or ≥ 12 months), salvage therapy (Salvage 1 or 2) and patient age (<55 or ≥ 55 years). The target population were adult patients who were 18 years or age and older with r/r ALL that had ≥70% leukemic blast cells exhibiting CD22, determined by flow cytometry. Patients were randomized to receive either inotuzumab 1.8mg/m2 per cycle (in a fractionated schedule of 0.8mg/m2 on Day 1 of each cycle and 0.5mg/m2 on Days 8 and 15), or the investigators’ choice of one of three standard of care regimens: fludarabine, cytarabine, and granulocyte colony- stimulating factor (FLAG), cytarabine plus mitoxantrone (CM) or high dose cytarabine (HIDAC). Efficacy of the study was determined by two primary endpoints: CR/CRi and overall survival. In addition to CR/CRi results, important secondary endpoints that helped evaluate efficacy were MRD and duration of remission. CR/CRi was pre-specified to include the first 218 patients (109 in the inotuzumab ozogamicin group and 109 in standard chemotherapy) that underwent randomization in the intention-to-treat analysis.

From the 218 patients, 88 patients receiving inotuzumab ozogamicin responded to therapy. About 64/88 (73%) and 21/88 (24%) achieved CR/CRi in Cycle 1 and Cycle 2 respectively of therapy. In the investigator’s choice of chemotherapy arm, only 32 patients responded with 29/32 (91%) of Cycle 1 and 1/32 (3%) of Cycle 2, achieving CR/CRi. The overall rate of CR/CRi in the inotuzumab group was significantly higher (80.7%, CI: 72.1-87.7%) vs. standard chemotherapy (29.4%, CI: 21-38.8%; p < 0.001). The number of patients who had MRD- negativity in the inotuzumab group were 69/88 (78.4%; 95% CI: 68.4-86.5) compared to the standard chemotherapy group where only 9/32 (28.1%) had MRD-negative disease. The median duration of remission was 5.4 months in the inotuzumab ozogamicin group (95% CI: 4.2-8.0), and 3.5 months in the standard chemotherapy group (95% CI: 2.9-6.6).

In the survival analysis, the ITT population’s median overall survival was 7.7 months (95%CI: 6.0 to 9.2) vs. 6.2 months (95%CI: 4.7-8.3) and the hazard ratio was 0.75 (97.5% CI: 0.57 to 0.99). The analysis of the OS did not meet pre-specified boundary of statistical significance. In addition, the proportion of patients who went on to HSCT were 79/164 (48%) in the inotuzumab ozogamicin group vs. 35/162 (22%) in the investigator’s choice of chemotherapy.

SWOG S0106

The FDA granted accelerated approval of gemtuzumab ozogamicin in May 2000 based on three phase II pilot studies in 142 adult patients with AML. This study aimed to examine the CR rate with the addition of gemtuzumab ozogamicin with standard induction chemotherapy compared to standard chemotherapy alone. Disease-free survival post-consolidation of the two comparator groups was also evaluated. Patients were randomized (stratified by age <35 vs ≥35) to receive induction therapy with daunorubicin (45 mg/m2 days 1-3), cytarabine (100mg/m2 on days 1-7) and gemtuzumab ozogamicin (6 mg/m2 on day 4) versus standard induction therapy with daunorubicin (60 mg/m2 days 1-3) and cytarabine (100mg/m2/ days 1-7). The results showed that 150/277 (66%) patients treated in the gemtuzumab ozogamicin cohort had a CR. This compared to 159/229 (69%) of patients who achieved CR with just chemotherapy alone (p <0.0025). Disease-free survival was not improved and fatal toxicity for patients in the gemtuzumab ozogamicin cohort vs. standard chemotherapy was 16/283 (16%) vs. 4/281 (1.4%), respectively. Pfizer voluntarily removed the drug from commercial marketing in 2010.

Gemtuzumab ozogamicin is now back in the commercial market based on three studies mentioned by the FDA:

• ALFA-0701 This was a randomized, open-label phase III trial with 271 patients who were newly-diagnosed with de novo AML from ages 50-70 years old. Patients were randomized (1:1) in receiving standard chemotherapy with gemtuzumab ozogamicin, and those with just standard chemotherapy. Efficacy was established on EFS (event-free survival), measured from date of randomization until induction failure, relapse, or death by any cause. Patients received induction therapy consisting of daunoruicin 60mg/m2 on Days 1-3), cytarabine (200mg/m2 on Days 1-7) and with (or without as a comparator) gemtuzumab ozogamicin at 3mg/m2 on Days 1, 4, and 7. Results showed that estimated median EFS was 17.3 months for patients receiving the therapy combination in comparison to 9.5 months with just standard chemotherapy. The hazard ratio was 0.66 (95% CI: 0.42-0.76).

• AML-19 This study was a randomized open-label phase III trial with 237 participants that looked at gemtuzumab ozogamicin monotherapy vs. best supportive care. Patient criteria included patients that were ≥ 75 or 61-75 years with a World Health Organization performance status (WHO-PS) greater than 2 or were unwilling to receive intensive chemotherapy. Patients in the gemtuzumab ozogamicin arm got induction therapy of 6mg/m2, then 3mg/m2 on at 2mg/m2 on Day 1 every 4 weeks for a total of 8 courses. Efficacy was established on improvement in overall survival (OS). Hazard ratio for OS was 0.69

Page | 6 of 13 ∞ (95%CI: 0.53-0.90). The median OS was 4.9 months (gemtuzumab ozogamicin cohort) vs. 3.6 months (best supportive care).

• MyloFrance-1 This study was a phase II, single-arm, open-label study with 57 patients with CD33-positive r/r AML. Patients received a single dose of gemtuzumab ozogamicin 3mg/m2 on days 1, 4, and 7 of therapy. Consolidation therapy consisted of cytarabine q12h for 3 days. Efficacy was established on CR and duration of remission. About 15/57 (26%) achieved CR and median relapse-free survival was 11.6 months. This was measured from first documentation of CR to the date of relapse/death.

Zynlonta® (loncastuximab tesirine-lpyl)

LOTIS-2

LOTIS-2 was an open-label, single-arm trial in 145 adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) after at least 2 prior systemic regimens. The trial excluded patients with bulky disease and active central nervous system lymphoma. Patients received Zynlonta 0.15 mg/kg every 3 weeks for 2 cycles, then 0.075 mg/kg every 3 weeks for subsequent cycles and received treatment until progressive disease, or unacceptable toxicity.

Of the 145 patients enrolled, the median age was 66 years (range 23 to 94), 59% male, and 94% had an ECOG performance status of 0 to 1. Race was reported in 97% of patients; of these patients, 90% were White, 3% were Black, and 2% were Asian. The diagnosis was DLBCL not otherwise specified (NOS) in 88% (including 20% with DLBCL arising from low grade lymphoma) and high-grade B-cell lymphoma in 8%. The median number of prior therapies was 3 (range 2 to 7), 63% with refractory disease, 17% with prior stem cell transplant, and 9% with prior chimeric antigen receptor (CAR) T-cell therapy.

Efficacy was established on the basis of overall response rate (ORR) as assessed by an Independent Review Committee (IRC) using Lugano 2014 criteria. The median follow-up time was 7.3 months (range 0.3 to 20.2). The confirmed ORR by IRC with Zynlonta was 48.3% (95% CI: 39.9%-56.7%) and the duration of overall response was a median of 10.3 months (95% CI: 6.9 – NE [not estimable]). The median time to response was 1.3 months (range 1.1 to 8.1).

Besponsa® (inotuzumab ozogamicin)

INO-VATE ALL trial observed 23/164 patients (14%) who had hepatotoxicity and hepatic veno- occulsive disease (VOD). VOD was reported up to 56 days from the last dose of treatment of inotuzumab ozogamicin, without intervening HSCT. In the study, 79 patients were able to proceed to subsequent HCT and 18/79 patients had VOD. There were 5/18 patients in the inotuzumab arm that had a fatal episode of VOD. The signs of VOD were observed at a mean of 15 days (range: 3-57days).

Thrombocytopenia and neutropenia were one of the most common AEs seen in the INO-VATE ALL trial that included 83/164 patients (51%) and 81/164 patients (49%) respectively. Grade 3 or 4 thrombocytopenia events occurred in 23/164 (14%) patients. In regard to neutropenia, 33/164 patients (20%) and 45/164 patients (27%) had Grade 3 or Grade 4 neutropenia respectively. Febrile neutropenia occurred in 43/164 patients (26%). Hemorrhagic events accounted for 54/164 patients (33%), with 5% who had either a Grade 3 or 4. One patient died from an intra- abdominal hemorrhage. Most observed hemorrhagic events were epistaxis in 24/164 patients (15%).

Patients who were in the inotuzumab arm had a higher day 100 post-HSCT mortality rate. There were 79/164 patients in the inotuzumab cohort and 35/162 patients in the investigator’s choice of therapy who were able to do a follow-up transplant. Patients who underwent HSCT showed that 31/79 patients (39%) in the inotuzumab cohort vs. 8/35 (23%) in the investigator’s choice of therapy had passed away within 100 days post-HSCT. The most common causes of death include VOD, multi-organ failure (MOF), infection or a mix of them together.

Mylotarg® (gemtuzumab ozogamicin)

Combination Therapy in Newly-Diagnosed Do Novo CD33+ AML

Safety data from ALFA-0701 showed discontinuation due to any AEs occurred in 21% of patients in the gemtuzumab ozogamicin combination therapy vs. 7% in the DA group (dauarubicin and cytarabine). The most frequent causes of discontinuations were due to thrombocytopenia (15%), VOD (3%), and septic shock (2%). Fatal adverse reactions occurred in 8 patients (6%) in the gemtuzumab ozogamicin arm compared to 3 patients (2%) in the DA arm. Causes of death include 3 that died from VOD, 4 from hemorrhage-related events, and 1 patient due to suspected cardiac cause. A large proportion of patients that had ≥ Grade 3 AEs were due to infection and hemorrhage during both induction and consolidation phases of therapy.

Monotherapy for Newly Diagnosed CD33+ AML

Safety data from AML-19 showed death due to any AE in 19 patients in the gemtuzumab ozogamicin arm compared to 23 patients in the best supportive care arm. There were 39 out of 111 patients with Grade ≥ 3 infection and 20 out of 111 patients with Grade ≥ 3 febrile neutropenia in the gemtuzumab ozogamicin arm, but those were comparable with best supportive care.

Zynlonta® (loncastuximab tesirine-lpyl)

The most common adverse reactions with Zynlonta are thrombocytopenia (58%), increased gamma-glutamyltransferase (57%), neutropenia (52%), anemia (51%), hyperglycemia (48%), transaminase elevation (41%), fatigue (38%), hypoalbuminemia (37%), rash (30%), edema (28%), nausea (23%), and musculoskeletal pain (23%). There are warnings and precautions regarding effusion and edema, myelosuppression, infections, cutaneous reactions, and embryo-fetal toxicity.
