A Phase 3 interventional study of sutimlimab (BIVV009) and placebo in Cold Agglutinin Disease, sponsored by Bioverativ, a Sanofi company. Completed at 53 sites in 14 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2022-12-23.
Sponsored by Bioverativ, a Sanofi company · Phase 3, Interventional, and Treatment
The purpose of Part A was to determine whether sutimlimab administration resulted in a greater than or equal to (>=)1.5 grams per deciliter (g/dL) increase in hemoglobin (Hgb) level and avoidance of transfusion in participants with primary cold agglutinin disease (CAD) without 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 primary CAD.
The planned total study duration per participant was approximately 1.5 to 2.5 years.
Exclusion criteria:
The above information was not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
Participants 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.

Baseline was defined as the last non-missing value prior to the first administration of study drug in Part A. ET visit/SFU visit was 9 weeks after administration of last dose (i.e., up to Week 184). Here, "0" in the number analyzed field signifies that none of participants were available for assessment at the specified timepoints.

FACIT-Fatigue scale consists of 13 questions assessed using a 5-point scale (0=not at all; 1 = a little bit, 2 = somewhat, 3 = quite a bit and 4 = very much). Responses to each question were added to obtain a total score. The Total score ranged from 0 to 52, with higher score indicating more fatigue. Baseline (Week 0) was defined as the last non-missing value prior to the first administration of study drug in Part A. ET visit/SFU visit was 9 weeks after administration of last dose (i.e., up to Week 184).

SF-12: 12 item-questionnaire assessed health-related quality of life (HRQOL), contained 12 items, categorized into 8 domains (subscales) of functioning and well-being: physical functioning, role-physical, role emotional, mental health, bodily pain, general health, vitality and social functioning, with each domain score ranged from 0 (poor health) to 100 (better health). Higher scores = good health condition. These 8 domains were further summarized into 2 summary scores, PCS and MCS that ranged from 0 (poor health) to 100 (better health). Higher scores = better HRQOL. Baseline (Week 0): last non-missing value prior to first administration of study drug in Part A. ET visit/SFU visit: 9 weeks after administration of last dose (i.e., up to Week 184).

EQ-5D-5L included 2 components: health state utility index (descriptive system) and Visual Analog Scale (VAS). EQ-5D descriptive system comprises 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 response option: no problem, slight problem, moderate problem, severe problem and extreme problems measured with Likert scale. EQ-5D-5L responses converted into single index utility score between 0 to 1. Higher score=better health. EQ-5D-5L VAS rated participant's current health state on scale from 0 (worst imaginable health) to 100 (best imaginable health). Baseline (Week 0): last non-missing value prior to first administration of study drug in Part A. ET visit/SFU visit: 9 weeks after administration of last dose (i.e., up to Week 184).

The PGIS is a self-reported scale. The PGIS is a 1-item questionnaire designed to assess participant's impression of disease severity using a 5-point scale ranging from 1 to 5, where 1=none, 2=mild, 3=moderate, 4=severe, 5=very severe. Higher scores indicated greater severity. ET visit/SFU visit was 9 weeks after administration of last dose (i.e., up to Week 184).

PGIC is a self-administered questionnaire to evaluate the improvement or worsening compared to the start of the study. PGIC was assessed on a 7-point Likert scale ranged from 1 (greatly improved) to 7 (greatly worsened). Categories were defined based on the PGIC scores as follows: 1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse and 7=very much worsen. Higher scores indicated greater severity. ET visit/SFU visit was 9 weeks after administration of last dose (i.e., up to Week 184).

Collected over Part A (both 6.5 g and 7.5 g cohorts): first dose (Day 0) up to Week 25; 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). Non-serious events are listed at a 5% frequency threshold.
