Sarclisa's Japan Approval: A New Hope for Multiple Myeloma Patients

The Japanese Ministry of Health, Labour and Welfare (MHLW) has approved Sarclisa (isatuximab) in combination with bortezomib, lenalidomide, and dexamethasone (VRd) for the treatment of adult patients with newly diagnosed multiple myeloma (NDMM) who are not eligible for autologous stem cell transplant. This approval, based on positive results from the IMROZ phase 3 study, offers a new treatment option for patients in Japan and expands the global reach of this innovative therapy.

Multiple myeloma is a type of blood cancer that affects plasma cells, a type of white blood cell responsible for producing antibodies. The disease is characterized by the presence of abnormal plasma cells in the bone marrow, leading to bone damage, anemia, and kidney problems. Despite available treatments, multiple myeloma remains an incurable cancer, and new treatment options are crucial for improving patient outcomes.

Sarclisa, a CD38 monoclonal antibody, has shown promising results in clinical trials when used in combination with other therapies. The IMROZ phase 3 study demonstrated that Sarclisa in combination with VRd significantly improved progression-free survival compared to VRd alone in transplant-ineligible NDMM patients. This improvement in survival, along with the positive safety profile of the combination, led to the approval in Japan.



The approval of Sarclisa in Japan for NDMM patients is a significant milestone for Sanofi, the company behind the drug. With this approval, Sarclisa is now available in more than 50 countries across multiple indications, including in combination with pomalidomide and dexamethasone (Pd) for relapsed or refractory multiple myeloma patients who have received at least two prior therapies, including lenalidomide and a proteasome inhibitor. Additionally, Sarclisa is approved in combination with carfilzomib and dexamethasone for patients with relapsed or refractory multiple myeloma who have received one to three prior lines of therapy.

The approval of Sarclisa in Japan for NDMM patients is expected to expand the market for this innovative therapy and provide new treatment options for patients in the region. As the incidence of multiple myeloma continues to increase in Japan and other Asian-Pacific nations, the need for new treatment approaches, particularly in the front-line setting, becomes more pressing. With this approval, physicians in Japan now have an important new option for their patients earlier in the treatment journey.

In conclusion, the approval of Sarclisa in Japan for newly diagnosed multiple myeloma patients represents a significant advancement in the treatment of this challenging disease. By offering a new treatment option with improved progression-free survival, Sarclisa has the potential to improve patient outcomes and expand the global reach of this innovative therapy. As the incidence of multiple myeloma continues to rise, the need for new treatment options remains critical, and the approval of Sarclisa in Japan is a welcome development in the fight against this disease.
