Frequently asked questions about BIVV020

What is BIVV020 used for?

BIVV020 is an investigational small molecule being developed by Sanofi for autoimmune haemolytic anaemia and transplant rejection. It is being studied in adults with cold agglutinin disease, a form of autoimmune haemolytic anaemia, and for the prevention and treatment of antibody-mediated rejection in transplant patients.

What does BIVV020 target?

BIVV020 targets the complement system, specifically the C1s protein, which is part of the classical complement pathway. By inhibiting C1s, BIVV020 aims to reduce complement-mediated destruction of red blood cells in autoimmune haemolytic anaemia and antibody-mediated tissue damage in transplant rejection.

Who makes BIVV020?

BIVV020 is developed by Sanofi, a multinational pharmaceutical company traded on the NASDAQ under the ticker SNY. Sanofi is conducting clinical trials to evaluate the safety, tolerability, and efficacy of BIVV020 in autoimmune haemolytic anaemia and transplant rejection.

What phase is BIVV020 in?

BIVV020 is in Phase 1 and Phase 2 clinical development. A Phase 1 trial in cold agglutinin disease has been completed, and a Phase 2 trial in antibody-mediated rejection is active but not recruiting. BIVV020 is investigational and has not been approved by regulatory authorities.

What clinical trials is BIVV020 in?

BIVV020 has two clinical trials. NCT04269551 is a completed Phase 1 safety and tolerability study in adults with cold agglutinin disease, enrolling 12 participants. NCT05156710 is an active Phase 2 study in prevention and treatment of antibody-mediated rejection, enrolling 48 participants across multiple countries.

Is BIVV020 the same as SAR445088?

Yes, BIVV020 is also known as SAR445088. The drug is referred to by both names in clinical trials and scientific literature. Researchers and investors may encounter either name when reviewing Sanofi's development programs for this investigational therapy.
