Study Endpoints

Primary Endpoints

Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs)
From first dose of study intervention up to 9 weeks after the last dose of study intervention (maximum duration: 49 weeks)

An Adverse Event (AE) was defined as any untoward medical occurrence in a participant who received study intervention and did not necessarily had to have a causal relationship with the treatment. Serious adverse events (SAEs) were defined as any untoward medical occurrence that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/ incapacity, was a congenital anomaly/birth defect, suspected transmission of any infectious agent via an authorized medicinal product, was a medically important event. TEAEs were defined as AEs that developed, worsened or became serious during the treatment-emergent period (from first dose of study intervention up to 9 weeks after the last dose of study intervention in the current study).

Number of Participants With Treatment-emergent Adverse Events of Special Interest (AESI)
From first dose of study intervention up to 9 weeks after the last dose of study intervention (maximum duration: 49 weeks)

An AE was defined as any untoward medical occurrence in a participant who received study intervention and did not necessarily had to have a causal relationship with the treatment. AESIs were AE (serious or non-serious) of scientific and medical concern specific to the Sponsor's product or program, for which ongoing monitoring and immediate notification by the investigator to the Sponsor was required.

Part A: Percentage of Participants With Response to Treatment
From Week 5 through Week 26

A participant was considered a responder: if he or she did not receive blood transfusion from Week 5 through Week 26 (end of treatment) and did not receive treatment for CAD beyond what was permitted per protocol. Additionally, participant's hemoglobin (Hgb) level must have increased to \>=1.5 grams per deciliter (g/dL) from baseline (defined as last Hgb value before administration of first dose of study drug) at treatment assessment timepoint (defined as average of values from the Week 23, 25, and 26 visits). Percentage of responders was calculated together with 95% exact Clopper-Pearson confidence interval (CI).

Part B: Number of Participants With Treatment-emergent Adverse Events (AEs) and Serious AEs (SAEs)
Part B, 6.5 g cohort: From first dose (Week 26) up to 149 weeks of treatment + 9 weeks of follow-up (i.e., up to Week 184); Part B, 7.5 g cohort: From first dose (Week 26) up to 137 weeks of treatment + 9 weeks of follow-up (i.e., up to Week 172)

Adverse Event (AE): any untoward medical occurrence in a participant who received study drug and did not necessarily have to have a causal relationship with the treatment. Treatment emergent serious adverse events (TESAEs) was defined as any untoward medical occurrence that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was congenital anomaly/birth defect, was medically important event. Treatment emergent adverse events (TEAEs): AEs that developed, worsened or became serious during the treatment-emergent (TE) period (from first investigational medicinal product \[IMP\] administration in Part B to last IMP administration + 9 weeks follow-up period).

Secondary Endpoints

Part A: Mean Change From Baseline in Hemoglobin (Hgb) Level at the Treatment Assessment Timepoint
Baseline (Week 0), treatment assessment timepoint (i.e., average of Week 23, 25 and 26)
Part A: Mean Change From Baseline in Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale Score at the Treatment Assessment Timepoint
Baseline (Week 0), treatment assessment timepoint (i.e., average of Week 23, 25 and 26)
Part A: Mean Change From Baseline in Total Bilirubin Levels at the Treatment Assessment Timepoint
Baseline (Week 0), treatment assessment timepoint (i.e., average of Week 23, 25 and 26)

ArmTypeDescription
SutimlimabEXPERIMENTALParticipants with body weight greater than or equal to (\>=) 39 kilograms (kg) to less than (\<) 75 kg and who had completed Part B of CARDINAL or CADENZA study were enrolled in the current study and received sutimlimab (BIVV009) 6.5 grams as intravenous (IV) infusion on Day 0, Day 7, Day 21 and thereafter every 2 weeks (maximum duration: 49 weeks) in the current study.
BIVV009/BIVV009EXPERIMENTALParticipants with primary CAD and without a recent history of blood transfusion during the last 6 months prior to enrollment in this study, received an intravenous (IV) infusion of BIVV009 6.5 g (for participants less than \[\<\]75 kilograms \[kg\]) or 7.5 g dose (for participants greater than or equal to \[\>=\]75 kg) on Day 0 and Day 7 and every 14 days thereafter in Part A up to Week 25. Participants who completed Part A per protocol through the end of treatment visit (Week 26), received placebo on Week 26 and continued to receive BIVV009 6.5 or 7.5 g in Part B, every 2 weeks starting at Week 27 for up to an additional 149 weeks (for 6.5 g) or 121 weeks (for 7.5 g). All participants who completed Part A elected to continue in Part B.
Placebo/BIVV009EXPERIMENTALParticipants with primary CAD and without a recent history of blood transfusion during the last 6 months prior to enrollment in this study, received an IV infusion of placebo matched to BIVV009 on Day 0 and Day 7 and every 14 days thereafter in Part A up to Week 25. Participants who completed Part A per protocol through the end of treatment visit (Week 26) received BIVV009 6.5 (if \<75 kg) or 7.5 g (if \>=75 kg) in Part B, on Week 26 and Week 27 and every 2 weeks thereafter for up to an additional 123 weeks (for 6.5 g) or 137 weeks (for 7.5 g). All participants who completed Part A elected to continue in Part B.

Frequently asked questions about sutimlimab

What is sutimlimab used for?

Sutimlimab is an investigational drug being developed for the treatment of Cold Agglutinin Disease (CAD), a rare autoimmune hemolytic anemia. It is currently in Phase 3 clinical development and has not been approved by regulatory authorities. Sutimlimab is being studied in adult patients with primary cold agglutinin disease.

What does sutimlimab target?

Sutimlimab is a small molecule that targets the complement system, specifically the C1s protein, which plays a key role in the classical complement pathway. By inhibiting C1s, sutimlimab aims to reduce complement-mediated hemolysis in patients with Cold Agglutinin Disease.

Who makes sutimlimab?

Sutimlimab is being developed by Sanofi, a multinational pharmaceutical company listed on the stock exchange under the ticker symbol SNY. Sanofi is conducting Phase 3 clinical trials to evaluate the safety and efficacy of sutimlimab in patients with Cold Agglutinin Disease.

What phase is sutimlimab in?

Sutimlimab is currently in Phase 3 clinical development for Cold Agglutinin Disease. It is an investigational drug, meaning it has not yet received regulatory approval. Two Phase 3 trials have been completed, with a total of 49 participants enrolled across multiple countries.

What clinical trials is sutimlimab in?

Sutimlimab has been studied in two completed Phase 3 trials. The first, NCT03347422, enrolled 42 participants with primary cold agglutinin disease without recent blood transfusion. The second, NCT05132127, enrolled 7 participants in Japan who had completed prior Phase 3 studies. Both trials were randomized, double-blind, and controlled.

Is sutimlimab the same as BIVV009?

Yes, sutimlimab is also known as BIVV009. The clinical trials for sutimlimab, including NCT03347422 and NCT05132127, use the name BIVV009 in their official titles, confirming that both names refer to the same investigational drug being developed by Sanofi.
