E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The purpose of Part A is to determine whether sutimlimab administration results in a greater than or equal to (>=)1.5 gram 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 is to evaluate the long-term safety and tolerability of sutimlimab in participants with primary CAD. |
|
E.2.2 | Secondary objectives of the trial |
Part A:
To assess the effect of BIVV009 on clinical events and laboratory parameters related to hemolysis and anemia in patients with primary
CAgD.
To assess the effect of BIVV009 on specific complications of CAgD (acrocyanosis, Raynaud's syndrome, hemoglobinuria, and thromboembolism)
To assess the effect of BIVV009 on quality of life (QOL) in patients with primary CAgD.
Part B:
The secondary objective of Part B is to investigate the durability of response during long-term treatment with BIVV009 in patients with primary CAgD. |

E.5 End points |
E.5.1 | Primary end point(s) |
Part A: Percentage of Participants With Response (R). A participant will
be considered a responder if he or she did not receive a blood
transfusion from Week 5 through Week 26 (EOT) and did not receive
treatment for primary cold agglutinin disease (CAD) beyond what is
permitted per protocol. Additionally, the participant's hemoglobin (Hgb)
level must meet the following criterion: Hgb increase greater than or
equal to (>=) 1.5 gram per deciliter (g/dL) from baseline (defined as the
last Hgb value before administration of the first dose of study drug.
Part B: Number of Participants With Treatment-emergent Adverse Events
(AEs) and Serious AEs (SAEs). An adverse event (AE) was any untoward
medical occurrence in a participant who received study drug without
regard to possibility of causal relationship. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Part A: Up to Week 26
Part B: Approximately 1 year from end of Week 26 of Part A |
|
E.5.2 | Secondary end point(s) |
Part A:
1. Mean Change From Baseline in Hemoglobin (Hgb) Level up to Week 26.
2. Mean Change From Baseline in Bilirubin up to Week 26.
3. Mean Change From Baseline in Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale Score (Quality of Life). 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 are added to obtain a total score. The range of possible scores is 0-52, with higher score indicating more fatigue.
4. Mean Change From Baseline in Lactate Dehydrogenase (LDH) up to Week 26.
5. Percentage of Participants With Solicited Symptomatic Anemia at End of Treatment (EOT). Symptomatic anemia is defined as fatigue,
weakness, shortness of breath, palpitations, fast heart beat, light headedness, and/or chest pain.
Part B:
6. Mean Change From Week 27 in Hemoglobin (Hgb) Level.
7. Mean Change From Week 27 in Bilirubin (total).
8. Mean Change From Week 27 in Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale Score (Quality of Life). FACITFatigue
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 are added to obtain a total score. The range of possible scores is 0-52, with higher score indicating more fatigue.
9. Mean Change From Week 27 in five level EuroQol five dimensions questionnaire (EQ-5D-5L). The EQ-5D descriptive system comprises 5
dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has a 5-level response: no problems, slight problems, moderate problems, severe problems, and extreme problems. A scale with score 0-100 is used to collect response on current health status. Higher the score better the health.
10. Mean Change From Week 27 in 12-item short form survey (SF-12). SF-12 health survey is a self-reported questionnaire to measure
participant's profile of functional health and well-being. It includes 12 questions (Q).
11. Patient's Global Impression of [Fatigue] Severity (PGIS) total score in different timepoints. PGIS is a 5-point response to the severity of the fatigue over the past weeks where 1 indicates No fatigue" to 5 as "very
severe". The assessments will be performed every 3 months beginning after Week 27 up to Week 77.
12. Patient's Global Impression of Change (PGIC) total score in different timepoints. PGIC is a 7-point response to the change of overall status of
quality of life where 1 indicates "Very much improved" to 7 as "very much worse". The assessments will be performed every 3 months
beginning after Week 27 up to Week 77.
13. Mean Change From Week 27 in Lactate Dehydrogenase (LDH) level.
14. Number of transfusions.
15. Mean Change From Week 27 in Haptoglobin.
16. Number of healthcare visits by type. Number of healthcare visits by type such as office visit, hospital ER visit, hospitalization, and ICU stay
will be reported for the approximately 1 year duration of Part B. |
