Sanofi Sarclisa sBLA Accepted for Priority Review
FDA has accepted for priority review a Sanofi supplemental BLA for Sarclisa (isatuximab) in combination with bortezomib, lenalidomide and dexamethasone (VRd) for treating patients with transplant-ineligible newly diagnosed multiple myeloma (NDMM). According to the company, if approved, Sarclisa would be the first anti-CD38 therapy in combination with standard-of-care VRd in this patient population. The user fee review action target date is 9/27.
The submission is based on data from the IMROZ Phase 3 clinical study. In 12/2023, the study met its primary endpoint at a planned interim analysis for efficacy, demonstrating statistically significant improvement in progression-free survival with Sarclisa in combination with VRd compared with VRd alone in transplant-ineligible patients with NDMM, Sanofi says. “The safety and tolerability of Sarclisa observed in this study was consistent with the established safety profile of Sarclisa and VRd,” it adds.
Sarclisa is described as a monoclonal antibody that binds to a specific epitope on the CD38 receptor on multiple myeloma cells, inducing distinct antitumor activity. It is designed to work through multiple mechanisms of action including programmed tumor cell death and immunomodulatory activities, Sanofi says.
