Sarclisa accepted for FDA priority review for the treatment of transplant-ineligible newly diagnosed multiple myeloma

• FDA Priority Review granted based on positive results from IMROZ phase 3 study
• If approved, Sarclisa would be the first anti-CD38 therapy in combination with standard-of-care treatment for patients with newly diagnosed transplant-ineligible multiple myeloma
• Pivotal IMROZ phase 3 study results to be featured during oral presentation at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting
  
  

The U.S. Food and Drug Administration (FDA) has accepted for Priority Review the supplemental Biologics License Application (sBLA) for the investigational use of Sarclisa (isatuximab) in combination with bortezomib, lenalidomide and dexamethasone (VRd) for the treatment of patients with transplant-ineligible newly diagnosed multiple myeloma (NDMM). If approved, Sarclisa would be the first anti-CD38 therapy in combination with standard-of-care VRd in newly diagnosed patients not eligible for transplant, which would be the third indication for Sarclisa in multiple myeloma. The target action date for the FDA decision is September 27, 2024. A regulatory submission is also under review in the European Union (EU).

“Despite recent advancements in multiple myeloma treatment, there remains a significant unmet need for new frontline therapies, particularly for transplant-ineligible patients who can face poor outcomes from the disease. The filing acceptances, as well as the FDA’s Priority Review designation, reinforce our confidence in Sarclisa as a potential best-in-class treatment and represent a critical step toward advancing this combination in a difficult-to-treat cancer.”

The sBLA, as well as the submission in the EU, is based on positive results from the IMROZ phase 3 clinical study evaluating the investigational use of Sarclisa in combination with standard-of-care VRd. In December 2023, the study met its primary endpoint at a planned interim analysis for efficacy, demonstrating statistically significant improvement in progression-free survival (PFS) with Sarclisa in combination with VRd compared with VRd alone in transplant-ineligible patients with NDMM. The safety and tolerability of Sarclisa observed in this study was consistent with the established safety profile of Sarclisa and VRd.

The IMROZ study is the fourth phase 3 study investigating Sarclisa combinations in NDMM patients to show superiority versus standard-of-care VRd and KRd, reinforcing its best-in-class potential. Results from the IMROZ study will also be featured during an oral presentation at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting and during the plenary scientific session at the 2024 European Hematology Association (EHA) Annual Congress.

Priority Review is granted to regulatory applications seeking approval for therapies that have the potential to provide significant improvements in the treatment, diagnosis or prevention of serious conditions.

The investigational use of Sarclisa in combination with VRd in patients with transplant-ineligible NDMM is currently under clinical development, and its safety and efficacy for this indication have not been fully evaluated by any regulatory authority.
