On March 27, 2020 Sanofi reported that the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion for Sarclisa (isatuximab) (Press release, Sanofi, MAR 27, 2020, View Source [SID1234555925]). The CHMP recommends Sarclisa in combination with pomalidomide and dexamethasone (pom-dex) for the treatment of adult patients with relapsed and refractory multiple myeloma (MM) who have received at least two prior therapies including lenalidomide and a proteasome inhibitor and have demonstrated disease progression on the last therapy.

The European Commission (EC) will review the CHMP recommendation and a final decision on the Marketing Authorisation Application for Sarclisa in the E.U. is expected in the coming months. Sarclisa has not been approved for commercial use in the E.U. Sarclisa was approved in the US on March 2 in combination with pomalidomide and dexamethasone (pom-dex) for the treatment of adults with RRMM who have received at least two prior therapies including lenalidomide and a proteasome inhibitor.
"Relapsed and refractory multiple myeloma is a complicated disease that continuously develops resistance to treatment, creating a significant need for continued innovation," said John Reed, M.D., Ph.D., Sanofi’s Global Head of Research & Development. "This positive CHMP opinion for Sarclisa brings us closer to our ambition to deliver a new treatment option for patients in Europe with relapsed and refractory multiple myeloma."
Sarclisa Phase 3 Study Results in Patients with RRMM
The CHMP positive opinion is based on data from ICARIA-MM, the first randomized Phase 3 trial to evaluate an anti-CD38 monoclonal antibody (mAB) in combination with pom-dex. In the ICARIA-MM study, Sarclisa added to pom-dex (Sarclisa combination therapy; n=154) demonstrated a statistically significant improvement of progression free survival (PFS) with a median PFS of 11.53 months compared to 6.47 months with pom-dex alone (n=153; HR 0.596, 95% CI: 0.44-0.81, p=0.0010). Sarclisa combination therapy also demonstrated a significantly greater overall response rate compared to pom-dex alone (60.4% vs. 35.3%, p<0.0001). In additional analyses, Sarclisa combination therapy compared to pom-dex alone showed a treatment benefit consistent across select subgroups reflective of real-world practice, including patients with high risk cytogenetics, those aged 75 years and older, patients with renal insufficiency, and patients who were refractory to lenalidomide.
The most common adverse reactions (all grades occurring in 20% or more of patients) in patients who received Sarclisa combination therapy were neutropenia (96%), infusion-related reactions (39%), pneumonia (31%), upper respiratory tract infection (57%) and diarrhea (26%). Serious adverse reactions that occurred in more than 5% of patients who received Sarclisa combination therapy included pneumonia (25.3%) and febrile neutropenia (12.3%). Permanent discontinuation of Sarclisa combination therapy due to an adverse reaction (Grades 3-4) occurred in 7% of patients, and 3% of patients discontinued due to an infusion-related reaction.
Multiple Myeloma: A Significant Burden to Patients
Multiple myeloma is the second most common hematologic malignancy1, with more than 138,000 new diagnoses of multiple myeloma worldwide yearly.2 In Europe, approximately 39,000 patients are diagnosed with multiple myeloma each year.3 Despite available treatments, multiple myeloma remains an incurable malignancy, and is associated with significant patient burden. Since multiple myeloma does not have a cure, most patients will relapse. Relapsed multiple myeloma is the term for when the cancer returns after treatment or a period of remission. Refractory multiple myeloma refers to when the cancer does not respond or no longer responds to therapy.
