A Study to Evaluate the Efficacy and Safety of Pegcetacoplan in Patients With Cold Agglutinin Disease (CAD)

Phase 3
Suspended
Conditions
Cold Agglutinin Disease
Interventions
Registration Number
NCT05096403
Lead Sponsor
Swedish Orphan Biovitrum
Brief Summary

The purpose of the study is to determine the efficacy of pegcetacoplan administration compared to placebo in increasing hemoglobin (Hgb) level from baseline and avoiding transfusion in participants with primary cold agglutinin disease (CAD).

Detailed Description

This is a blind (actual treatment not disclosed to Investigator or participant) study to study pegcetacoplan in people with cold agglutinin disease. The study will consist of a 4-week screening period where selected tests will be conducted to ensure that the patient is eligible to participate in the study, followed by Part A, a 24-week blinded treatment period where the participants will receive either pegcetacoplan or a placebo treatment, looking like pegcetacoplan but with no effect. After this period, the participants will move into Part B, a 24-week period where they will all receive pegcetacoplan. Part C is a 48-week maintenance period with pegcetacoplan for all participants. After the end of treatment participants will undergo a safety follow visit about 8 weeks after last dose.

All eligible study participants will receive pegcetacoplan or placebo treatment, administered via subcutaneous infusion twice a week at home. The subcutaneous infusion requires two small needles to be inserted into the fatty layer of tissue under the skin and the investigational medication will flow into the body. Study participants and/or caregivers will be trained on home administration of pegcetacoplan.

Primary Outcome Measures
NameTimeMethod
Response (R)Week 24

A participant will be considered to have a response if the Hgb level increases greater than or equal to (\>=) 1.5 gram per deciliter (g/dL) from baseline and this increase is maintained from Week 16 through Week 24 in absence of blood transfusion from Week 5 through Week 24.

Secondary Outcome Measures
NameTimeMethod
Transfusion avoidance from Week 5 to Week 24Week 24

Percentage of patients who did not received a blood transfusion between Week 5 and Week 24 will be assessed

Change from Baseline to Week 24 in Hemoglobin (Hgb) level.Week 24

Mean change from Baseline to Week 24 in Hemoglobin (Hgb) level will be assessed

Change From Baseline to Week 24 in Functional Assessment of Cancer Therapy-Anemia/Fatigue (FACT-An) Scale Score (Quality of Life)Week 24

FACT-An consists consists of 33 questions related to general quality of life and to the impact of fatigue and other anemia-related symptoms 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.

Number of PRBC transfusions from Week 5 to Week 24.Week 24

Number of blood transfusions received between Week 5 and Week 24 will be assessed

Change from Baseline to Week 24 in markers of hemolysisWeek 24

Mean change from baseline to Week 24 in Lactate dehydrogenase (LDH) level; Haptoglobin level; Indirect bilirubin level; Absolute reticulocyte counts (ARC).

Normalization of markers of hemolysis at Week 24Week 24

Percentage of patients with LDH level; Indirect bilirubin level and ARC within normal ranges.

Change From Baseline to Week 24 in 12-item short form survey (SF-12)24 weeks

SF-12 health survey is a self-reported questionnaire to measure participant's profile of functional health and well-being. It includes 12 questions.

Change From Baseline to Week 24 in five level EuroQol five dimensions questionnaire (EQ-5D-5L)Week 24

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.
