研究概览
简要总结
The purpose of Part A was to determine whether sutimlimab administration resulted in a greater than or equal to (>=) 2 grams per deciliter (g/dL) increase in hemoglobin (Hgb) levels or increased Hgb to >= 12 g/dL and obviated the need for blood transfusion during treatment in participants with primary cold agglutinin disease (CAD) who had a recent history of blood transfusion. The purpose of Part B was to evaluate the long-term safety and tolerability of sutimlimab in participants with CAD.

研究组 & 干预措施
BIVV009
Participants with primary CAD who had a recent history of transfusion (defined as at least 1 transfusion during the last 6 months prior to screening) received an intravenous (IV) infusion of BIVV009 6.5 grams (g) (if body weight was less than [<] 75 kilograms [kg]) or BIVV009 7.5 g (if body weight was 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) could continue to receive BIVV009 in Part B, every 2 weeks starting at Week 27 for up to an additional 149 weeks. All participants who completed Part A elected to continue in Part B.

结局指标
主要结局
Part A: Percentage of Participants With Response to Treatment
时间窗: From Week 5 through Week 26
A participant was considered a responder: if he or she did not receive a blood transfusion from Week 5 through Week 26 (end of treatment in Part A) and did not receive treatment for CAD beyond what was permitted per protocol. Additionally, the participant's hemoglobin (Hgb) level must meet either of the following criteria: Hgb level \>= 12 grams per deciliter (g/dL) at the treatment assessment endpoint (defined as the average of the values from the Week 23, 25, and 26 visits), or Hgb increased \>= 2 g/dL from baseline (defined as the last Hgb value before administration of the first dose of study drug) at treatment assessment endpoint. Percentage of responders was calculated together with a 95% exact Clopper-Pearson confidence interval (CI).
Part B: Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs)
时间窗: Part B, 6.5 g cohort: From first dose (Week 27) up to 143 weeks of treatment + 9 weeks of follow-up (i.e., up to Week 179); Part B, 7.5 g cohort: From first dose (Week 27) up to 149 weeks of treatment + 9 weeks of follow-up (i.e., up to Week 185)
An Adverse Event (AE) was defined as any untoward medical occurrence in a participant who received study drug and did not necessarily have to have a causal relationship with the treatment. 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 a congenital anomaly/birth defect, was a medically important event. TEAEs were defined as AEs that developed, worsened or became serious during the treatment-emergent (TE) period (from the first investigational medicinal product \[IMP\] administration in Part B to the last IMP administration + 9 weeks follow up period).
