adverse events: AEs, serious adverse events: SAEs, adverse events of special interest: AESIs, electrocardiograms: ECGs
A response is defined as decrease of ≥1 point from baseline in adjusted INCAT disability score at Week 24
Lasting response is defined as a decrease of ≥1 point in adjusted INCAT disability score
Lasting response is defined as a decrease of ≥1 point in adjusted INCAT disability score at week 48 versus baseline.
A response is defined as a decrease of ≥1 point in adjusted INCAT disability score at Week 48 versus week 24.
Relapse will be defined as ≥1-point increase in adjusted Inflammatory neuropathy cause and treatment (INCAT) disability score. The Investigator/rater will evaluate the level of impairment in participants? arms and legs each on a scale of 0 (least impaired) to 5 (most impaired), in the context of a neurological examination, and will record the added scores (range 0 to 10) per the INCAT reporting instructions. A low score reflects no or minimal disability eg, no arm dysfunction or walking normally, whereas higher scores indicate more disability eg, wheelchair bound or no purposeful arm movement.

Number of participants reported with adverse events during 76 weeks of treatment and 22 weeks of follow-up.
A naive participant was a participant who did not use sutimlimab prior to enrollment. A switcher was a participant who used sutimlimab prior to enrollment. A naive participant was a responder if the platelet count was \>=50 × 10\^9/liter (L) at \>=50 percent (%) of scheduled visits, or for participants with baseline platelet count \<15 × 10\^9/L, a \>=20 × 10\^9/L increase in platelet count from baseline at \>=50% of scheduled visits, without receiving rescue immune thrombocytopenia (ITP) therapy. A switcher was a responder if the maintenance platelet count was \>=30 × 10\^9/L at \>=50% of scheduled visits, without receiving rescue ITP therapy.

SAR445088 is an investigational small molecule developed by Sanofi for immune-mediated neurological and hematologic conditions. It is being studied in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and immune thrombocytopenia (ITP). It remains in clinical development and is not described as approved.
SAR445088 is being studied for the treatment of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), a neurological condition. A Phase 2 proof-of-concept study, NCT04658472, evaluated SAR445088 in adults with CIDP across the United States, Canada, China, France, Germany, Italy, Netherlands, Poland, Serbia and Spain.
SAR445088 targets C1s, a protein component of the complement system. By binding C1s, the drug is designed to modulate complement-mediated activity, which is relevant to immune-driven conditions such as CIDP and immune thrombocytopenia. The target class is protein.
SAR445088 is developed by Sanofi, which trades under the ticker SNY. Sanofi is the sponsor of the clinical program studying the drug in chronic inflammatory demyelinating polyradiculoneuropathy and immune thrombocytopenia.
SAR445088 is in Phase 2 development. Two Phase 2 studies have been completed: NCT04658472 in chronic inflammatory demyelinating polyradiculoneuropathy and NCT04669600 in immune thrombocytopenia. The drug is investigational and is not described as approved.
SAR445088 has been studied in two completed Phase 2 trials. NCT04658472 was a proof-of-concept study in chronic inflammatory demyelinating polyneuropathy with 98 participants. NCT04669600 was a Phase 2a study in persistent or chronic immune thrombocytopenia with 12 participants across the United States, Czechia, Germany, Netherlands, Spain and the United Kingdom.
Yes, SAR445088 is also known as BIVV020. Both names refer to the same investigational compound, and the intravenous form is referred to as SAR445088 (IV). The drug is developed by Sanofi and targets C1s.
