Study summary

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.

What researchers measure

Primary outcomes

  1. Part A: Percentage of Participants With Response to Treatment

    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).

    Time frame: From Week 5 through Week 26

  2. Part B: Number of Participants With Treatment-emergent Adverse Events (AEs) and Serious AEs (SAEs)

    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).

    Time frame: 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)

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).

SecondaryPart B: Change From Baseline in 5-level European Quality of Life 5- Dimensions 5-Level Questionnaire (EQ-5D-5L) Health State Utility Index and VAS Scores at Each Specified Time Points

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).

SecondaryPart B: Number of Participants With Response to Participant's Global Impression of (Fatigue) Severity (PGIS) Questionnaire at Each Specified Time Points

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).

SecondaryPart B: Number of Participants With Response to Participant's Global Impression of Change (PGIC) Questionnaire at Each Specified Time Points

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).
