Sanofi announces €300 million collaboration with Blackstone Life Sciences to advance an innovative treatment for multiple myeloma

  • Investment will accelerate the overall Sarclisa® development program
  • Sanofi will continue to fully manage the clinical program and retain full rights and control of Sarclisa® (isatuximab)

Sanofi and Blackstone (NYSE: BX) today announced a strategic, risk-sharing collaboration under which funds managed by Blackstone Life Sciences (BXLS) will contribute up to €300 million to accelerate the global pivotal studies and the clinical development program for the subcutaneous formulation and delivery of the anti-CD38 antibody Sarclisa®, to treat patients with multiple myeloma (MM). If successful, BXLS will be eligible to receive royalties on future subcutaneous sales. The pivotal study for the subcutaneous formulation is expected to begin in the second half of 2022.

For the Sarclisa® subcutaneous formulation delivery, Sanofi has partnered with drug delivery technology innovator company Enable Injections, Inc. to advance the development of a subcutaneous delivery for Sarclisa® with the goal of offering a unique patient-centric treatment experience.

To-date, Sarclisa® has received regulatory approval for intravenous administration to treat certain patients with relapsed MM and is under investigation across the MM treatment continuum of care for other hematologic malignancies and solid tumors.

About Sarclisa®

Sarclisa® is a monoclonal antibody that targets a specific epitope on the CD38 receptor on MM cells. It is designed to work through multiple mechanisms of action including programmed tumor cell death (apoptosis) and immunomodulatory activity. CD38 is highly and uniformly expressed on the surface of MM cells, making it a potential target for antibody-based therapeutics such as Sarclisa®.

Based on the Phase 3 ICARIA-MM study, Sarclisa® is approved in a number of countries in combination with pomalidomide and dexamethasone for the treatment of patients with relapsed refractory MM (RRMM) who have received ≥2 prior therapies, including lenalidomide and a proteasome inhibitor. Based on the Phase 3 IKEMA study, Sarclisa® is also approved in combination with carfilzomib and dexamethasone in the U.S. for the treatment of patients with RRMM who have received 1–3 prior lines of therapy and in the European Union for patients with MM who have received at least 1 prior therapy. In the U.S., the generic name for Sarclisa® is isatuximab-irfc, with irfc as the suffix designated in accordance with Nonproprietary Naming of Biological Products Guidance for Industry issued by the U.S. Food and Drug Administration (FDA).

Sarclisa® continues to be evaluated in multiple ongoing Phase 3 clinical trials in combination with current standard treatments across the MM treatment continuum. It is also under investigation for the treatment of other hematologic malignancies and solid tumors. The safety and efficacy of these additional uses have not been reviewed by any regulatory authority worldwide.

About Multiple Myeloma

Multiple myeloma (MM) is the second most common hematologic malignancy,1 with more than 130,000 new global annual diagnoses2. Despite available treatments, MM remains an incurable malignancy and is associated with significant patient burden. Since MM does not have a cure, most patients will relapse. Relapsed MM is the term for when the cancer returns after treatment or a period of remission. Refractory MM refers to when the cancer does not respond or no longer responds to therapy.
