Isatuximab IV

Sanofi · Phase 3 active Small molecule ✓ Verified May 2026

Isatuximab IV is a CD38-targeting monoclonal antibody Small molecule drug developed by Sanofi. It is currently in Phase 3 development for Multiple myeloma (in combination with pomalidomide and dexamethasone), Multiple myeloma (in combination with carfilzomib and dexamethasone). Also known as: SAR650984, SARCLISA®.

Isatuximab is a monoclonal antibody that binds to CD38 on the surface of multiple myeloma cells, triggering their destruction through multiple immune mechanisms.

Isatuximab IV is used to treat multiple myeloma, including relapse, refractory, and newly diagnosed cases with severe renal impairment. It is administered intravenously as part of a combination therapy, such as with CM336, a BCMA/CD3 bispecific antibody.

If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Oncology Phase 3 boost +3.0pp
    Oncology Phase 3 trials have higher approval rates (~61%) than the cross-industry average due to clearer endpoints and FDA oncology pathway.
  • Big-pharma sponsor +3.0pp
    Sanofi is a top-20 pharma sponsor — historical approval rates run ~3pp above average due to scale, regulatory experience, and trial-design quality.

Mechanism of action

Isatuximab targets CD38, a surface antigen highly expressed on multiple myeloma cells. By binding to CD38, it activates antibody-dependent cellular cytotoxicity (ADCC), antibody-dependent cellular phagocytosis (ADCP), and complement-dependent cytotoxicity (CDC), leading to direct tumor cell death. It also modulates the immunosuppressive tumor microenvironment by reducing CD38+ regulatory T cells and myeloid-derived suppressor cells.
