Participant Flow
Recruitment Details | The study was conducted at 27 sites in 13 countries. Out of 66 screened participants, a total of 42 participants were enrolled and randomized from 17 March 2018 to 30 March 2020. This study consisted of 2 Parts: Part A and Part B. |
Pre-assignment Details | Participants were stratified based on baseline body weight to receive BIVV009 6.5 grams (g) (if <75 kg) or 7.5 g (if >=75 kg). As planned, data presented as: 1) Dose-wise (2 dose cohorts: BIVV009 6.5 g & BIVV009 7.5 g) for safety outcome measures and adverse events (AEs). 2) combined population (BIVV009 at any dose) for efficacy outcome measures. |

Participants with primary Cold Agglutinin Disease (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. | 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 IV infusion of placebo matched to BIVV009 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 BIVV009 6.5 (if <75 kg) or 7.5 g (if >=75 kg) in Part B, on Week 26 and Week 27 and every 2 weeks thereafter for up to an additional 123 weeks (for 6.5 g) or 137 weeks (for 7.5 g). All participants who completed Part A elected to continue in Part B. |
