  Isatuximab-irfc (e.g., Sarclisa)

Description:
Isatuximab-irfc is a CD38 directed cytolytic immunoglobulin G1 (IgG1) monoclonal antibody (mAb) that binds to CD38 expressed on the surface of hematopoietic and tumor cells, including multiple myeloma MM) cells.  It induces apoptosis of tumor cells and activation of immune effector mechanisms including antibody-dependent cell mediated cytotoxicity (ADCC), antibody-dependent cellular phagocytosis (ADCP), and complement dependent cytoxcity (CDC).  Isatuximab-irfc can activate natural killer (NK) cells in the absence of CD38-positive target tumor cells and suppresses CD38-positive T-regulatory cells.
 
Regulatory Status
 
Isatuximab-irfc (e.g., SARCLISA®) was approved by the FDA on March 2, 2020.  It is indicated in combination with pomalidomide and dexamethasone, for the treatment of adult individuals with MM who have received at least two prior therapies including lenalidomide and a proteasome inhibitor (PI).  Isatuximab-irfc was also granted Orphan Drug designation.
 
On March 31, 2021, the Food and Drug Administration approved Isatuximab-irfc (e.g., Sarclisa) in combination with carfilzomib and dexamethasone, for the treatment of adult individuals with relapsed or refractory multiple myeloma who have received 1 to 3 prior lines of therapy.

Does Not Meet Primary Coverage Criteria Or Is Investigational For Contracts Without Primary Coverage Criteria
 
Isatuximab-irfc (SARCLISA®) does not meet member benefit certificate primary coverage criteria for any other indication.
 
For members with contracts without primary coverage criteria, isatuximab-irfc (SARCLISA®) is considered investigational for any other indication.
 
Investigational services are specific contract exclusions in most member benefit certificates of coverage.

Rationale:
Multiple myeloma (MM) is characterized by the neoplastic proliferation of clonal plasma cells producing a monoclonal immunoglobulin.  These clonal plasma cells proliferate in the bone marrow and can result in extensive skeletal destruction with osteolytic lesions, osteopenia, and/or pathologic fractures.  Additional disease-related complications include hypercalcemia, renal insufficiency, anemia and infections.
 
For those patients with symptomatic MM initial therapy depends on risk stratification (i.e. high or standard risk disease), eligibility for autologous hematopoietic cell transplantation (HCT), and resources available.  Almost all patients with MM who survive initial treatment will eventually relapse and require further therapy.  Treatment options for those with relapsing remitting MM (RRMM) include HCT, a rechallenge of the previous chemotherapy regimen, or a trial of a new regimen. The decision for the next step in therapy includes risk stratification, prior treatments used, and the duration or response to those treatments.  
 
In the triple drug regimens that are increasingly the norm for treating MM, patients will typically receive one or two active agents in combination with dexamethasone and are treated until disease progression, after which another dexamethasone containing regimen may be given.
 
The approval for isatuximab-irfc (SARCLISA®) is based on the Phase 3 ICARIA-MM (NCT 02990338) trial which examined the use of Isatuximab-irfc with Pomalyst (pomalidomide) and dexamethasone compared to Pomalyst with dexamethasone (Pd).  ICARIA-MM is an open-label, multicenter, phase 3 trial that included 307 patients with RRMM who had received at least 2 lines of prior therapy (median of 3) and were randomly assigned to receive pomalidomide plus dexamethasone with or without isatuximab-irfc.
 
At a median follow-up of 11.6 months, progression free survival (PFS) was 11.53 months with the isatuximab regimen compared with 6.47 months with Pd alone. PFS was seen across multiple patient subgroups, including patients with high cytogenetic risk, patients refractory to Revlimid, patients refractory to a proteasome inhibitor, am patients refractory to Revlimid and a proteasome inhibitor.   Overall survival (OS) data at 1 year was 72% with the isatuximab arm compared with 63% with Pd-alone arm.   There was also a greater overall response rate in the isatuximab arm of 93% versus 54% in the non-isatuximab arm.  The median duration of treatment was 41 weeks in the isatuximab arm compared to 24.0 weeks in the Pomalyst-alone arm.  56.5% of patients discontinued treatment in the isatuximab arm compared to 74.5% in the Pomalyst alone arm, with progressive disease being the primary reason for discontinuation in both arms.   There was a higher rate of grade 3 or greater adverse events 86.8% of the isatuximab combination arm compared with 70.5% of the Pomalyst only arm. The rate of serious TEAEs were 61.8% versus 53.7% respectively.  
 
2021 Update
The efficacy and safety of SARCLISA in combination with carfilzomib and dexamethasone were evaluated in IKEMA (NCT03275285), a multicenter, multinational, randomized, open-label, 2­arm, phase 3 study in patients with relapsed and/or refractory multiple myeloma. Patients had received one to three prior lines of therapy. Patients were eligible for inclusion if they had an ECOG status of 0-2, platelets ≥50,000 cells/mm3, absolute neutrophil count ≥1 × 109/L, creatinine clearance ≥15 mL/min/1.73 m2 (MDRD formula), AST ≤3 × ULN, and ALT ≤3 × ULN.
 
A total of 302 patients were randomized in a 3:2 ratio to receive either SARCLISA in combination with carfilzomib and dexamethasone (Isa-Kd, 179 patients) or carfilzomib and dexamethasone (Kd, 123 patients). Treatment was administered in both groups in 28-day cycles until disease progression or unacceptable toxicity. SARCLISA 10 mg/kg was administered as an intravenous infusion weekly in the first cycle and every two weeks thereafter. Carfilzomib was administered as an intravenous infusion at the dose of 20 mg/m2 on days 1 and 2; 56 mg/m2 on days 8, 9, 15, and 16 of cycle 1; and at the dose of 56 mg/m2 on days 1, 2, 8, 9, 15, and 16 for subsequent cycles of each 28-day cycle. Dexamethasone (intravenously on the days of isatuximab-irfc and/or carfilzomib infusions, and orally on the other days) 20 mg was given on days 1, 2, 8, 9, 15, 16, 22, and 23 for each 28-day cycle. On the days where both SARCLISA and carfilzomib were administered, dexamethasone was administered first, followed by SARCLISA infusion, then followed by carfilzomib infusion.
Overall, demographic and disease characteristics at baseline were similar between the two treatment groups. The median patient age was 64 years (range 33-90), 9% of patients were ≥75 years, 71% were White, 17% Asian, and 3% Black or African American. The proportion of patients with renal impairment (eGFR<60 mL/min/1.73 m2) was 24% in the Isa-Kd group versus 15% in the Kd group. The International Staging System (ISS) stage at study entry was I in 53%, II in 31%, and III in 15% of patients. Overall, 24% of patients had high-risk chromosomal abnormalities at study entry; del(17p), t(4;14), t(14;16) were present in 11%, 14%, and 2% of patients, respectively. In addition, gain(1q21) was present in 42% of patients.
 
The median number of prior lines of therapy was 2 (range 1-4) with 44% of patients who received 1 prior line of therapy. Overall, 90% of patients received prior proteasome inhibitors, 78% received prior immunomodulators (including 43% who received prior lenalidomide), and 61% received prior stem cell transplantation. Overall, 33% of patients were refractory to prior proteasome inhibitors, 45% were refractory to prior immunomodulators (including 33% refractory to lenalidomide), and 21% were refractory to both a proteasome inhibitor and an immunomodulator.
 
The median duration of treatment was 80 weeks for the Isa-Kd group compared to 61 weeks for the Kd group.
 
The efficacy of SARCLISA was based upon PFS. PFS results were assessed by an Independent Response Committee based on central laboratory data for M-protein and central radiologic imaging review using the IMWG criteria. The improvement in PFS represented a 45% reduction in the risk of disease progression or death in patients treated with Isa-Kd compared to patients treated with Kd. (FDA, 2020)
 
2022 Update
Patients with relapsed/refractory multiple myeloma (RRMM) experience several relapses and become refractory to successive therapies. In the ICARIA-MM trial (NCT02990338), isatuximab plus pomalidomide-dexamethasone prolonged median progression-free survival (PFS) in patients with RRMM. This subgroup analysis of ICARIA-MM assessed the treatment benefit of isatuximab by prior lines of therapy and refractory status. A total of 307 patients were randomized to isatuximab-pomalidomide-dexamethasone (n = 154) or pomalidomide-dexamethasone (n = 153). Isatuximab (10 mg/kg intravenously) was given weekly in the first 28-day cycle, then every other week. Standard pomalidomide-dexamethasone doses were given. PFS was assessed by prior lines and refractory status. Overall, 102 (66 %) patients receiving isatuximab-pomalidomide-dexamethasone and 101 (66 %) patients receiving pomalidomide-dexamethasone had received 2-3 prior lines; 52 (34 %) and 52 (34 %) had received >3 prior lines, respectively. Median PFS was higher with isatuximab-pomalidomide-dexamethasone versus pomalidomide-dexamethasone for patients who received 2-3 prior lines of therapy (12.3 vs. 7.8 months) and >3 prior lines of therapy (9.4 vs. 4.3 months). Median PFS was higher with isatuximab-pomalidomide-dexamethasone versus pomalidomide-dexamethasone for patients who were lenalidomide-refractory (11.4 vs. 5.6 months), lenalidomide-refractory at last line (11.6 vs. 5.7 months), refractory to a proteasome inhibitor (PI) (11.4 vs. 5.6 months), and double-refractory (11.2 vs. 4.8 months). Overall response rate (ORR) in patients receiving isatuximab-pomalidomide-dexamethasone versus pomalidomide-dexamethasone was 59.0 % versus 31.4 % in lenalidomide-refractory; 60.2 % versus 32.2 % in PI-refractory; and 58.6 % versus 29.9 % in double-refractory patients. Isatuximab-pomalidomide-dexamethasone improved PFS and ORR regardless of prior lines of therapy or refractory status, consistent with the benefit in the overall population. (Bringhen S, Pour L, Vorobyev V,et.al., 2021)
 
2023 Update
The IKEMA study (Randomized, Open Label, Multicenter Study Assessing the Clinical Benefit of Isatuximab Combined With Carfilzomib [Kyprolis®] and Dexamethasone Versus Carfilzomib With Dexamethasone in Patients With Relapse and/or Refractory Multiple Myeloma Previously Treated With 1 to 3 Prior Lines; #NCT03275285) was a randomized, open-label, multicenter phase 3 study investigating isatuximab plus carfilzomib and dexamethasone (Isa-Kd) vs Kd in patients with relapsed multiple myeloma. This subanalysis analyzed the depth of response of Isa-Kd vs Kd. The primary end point was progression-free survival (PFS); secondary end points included overall response rate, very good partial response or better (VGPR) rate, complete response (CR) rate, and minimal residual disease (MRD) negativity rate (assessed in patients with VGPR by next-generation sequencing at a 10-5 sensitivity level). At a median follow-up of 20.7 months, deeper responses were observed in the Isa-Kd arm vs the Kd arm, with VGPR 72.6% vs 56.1% and CR of 39.7% vs 27.6%, respectively. MRD negativity occurred in 53 (29.6%) of 179 patients in the Isa-Kd arm vs 16 (13.0%) of 123 patients in the Kd arm, with 20.1% (Isa-Kd, 36 of 179 patients) vs 10.6% (Kd, 13 of 123 patients) reaching MRD-negative CR status. Achieving MRD negativity resulted in better PFS in both arms. A positive PFS treatment effect was seen with Isa-Kd in both MRD-negative patients (hazard ratio, 0.578; 95% CI, 0.052-6.405) and MRD-positive patients (hazard ratio, 0.670; 95% CI, 0.452-0.993). Exploratory analysis indicates that both current CR and MRD-negative CR rates are underestimated due to M-protein interference (potential adjusted CR rate, 45.8%; potential adjusted MRD-negative CR rate, 24.0%). In conclusion, there was a clinically meaningful improvement in depth of response with Isa-Kd. The CR rate in Isa-Kd was 39.7%. Mass spectrometry suggests that the potential adjusted CR rate could reach an unprecedented 45.8% of patients treated with Isa-Kd. (Martin T, Mikhael J, Hajek R, 2022)
 
2024 Update
Longer-term outcomes with the anti-CD38 antibody isatuximab in combination with carfilzomib-dexamethasone (Isa-Kd) were evaluated in the randomized Phase 3 trial IKEMA (NCT03275285), in a prespecified, follow-up analysis of progression-free survival (PFS, primary study endpoint), final complete response (CR) using Hydrashift Isa immunofixation assay, minimal residual disease (MRD) negativity, and safety. Enrolled patients had relapsed/refractory multiple myeloma (1-3 prior treatment lines). Isa 10 mg/kg was administered intravenously weekly in cycle 1 then biweekly. Efficacy analyses were performed in the intent-to-treat population (Isa-Kd: n = 179, Kd: n = 123) and safety evaluated in treated patients (Isa-Kd: n = 177, Kd: n = 122). Consistent with the primary interim analysis, the addition of Isa to Kd prolonged PFS (HR 0.58, 95.4% CI: 0.42-0.79; median PFS 35.7 [95% CI: 25.8-44.0] vs 19.2 [95% CI: 15.8-25.0] months). PFS benefit was observed with Isa-Kd across subgroups, including patients with poor prognosis. The stringent CR/CR rate was 44.1% vs 28.5% (odds-ratio: 2.09, 95% CI: 1.26-3.48), the MRD negativity rate 33.5% vs 15.4% (odds-ratio: 2.78, 95% CI: 1.55-4.99) and the MRD negativity CR rate 26.3% vs 12.2%, with Isa-Kd vs Kd. The safety profile of Isa-Kd was similar to that reported in the prior interim analysis. These findings further support Isa-Kd as a standard-of-care treatment for relapsed multiple myeloma patients.
