What was measured
All human-antihuman antibody (HAHA) samples were first tested in a screening assay to identify potential HAHA positives. Next, samples that tested positive in the screening assay were further tested in the confirmation assay to determine the specificity of the signal to ofatumumab. Confirmed positive samples were reported as positive.
Analysis population: Safety Population. Only those participants with post-ofatumumab HAHA results were analyzed.
Groups in this outcome
300 mg Ofatumumab, Wk. 1; 1000/2000 mg Ofatumumab, Wk. 2-4/2-5
Participants received ofatumumab intravenously (IV) in Cycle 1 (defined as a treatment period of up to 4 weeks \[Weeks (Wk.) 1 through 4\]) (300 milligrams \[mg\] at Week 1 and 1000 mg at Weeks 2 through 4) and were followed up for 11 weeks (Weeks 5-16). After Week 16, during the Redosing Cycle (RC), participants who had Minor Response or stable disease after Cycle 1 and had not received another Waldenstrom's Macroglobulinemia (WM) therapy received 300 mg IV ofatumumab at Week 1 and 2000 mg IV ofatumumab at Weeks 2 through 5. Participants who achieved a response in either Cycle 1 or the RC and subsequently progressed before 36 months entered Cycle 2 of treatment and received IV ofatumumab 300 mg at Week 1 and IV ofatumumab 2000 mg during Weeks 2 through 5.
300 mg Ofatumumab, Wk. 1; 2000 mg Ofatumumab, Wk. 2-5
Participants received ofatumumab IV at 300 mg at Week 1 and 2000 mg at Weeks 2 through 5 in Cycle 1 (defined as a treatment period of up to 5 weeks \[Weeks 1 through 5\]) and were followed up for 10 weeks (Weeks 6-16). After Week 16, during the RC, participants who had Minor Response or stable disease after Cycle 1 and had not received another WM therapy received 300 mg IV ofatumumab at Week 1 and 2000 mg IV ofatumumab at Weeks 2 through 5. Participants who achieved a response and subsequently progressed before 36 months entered Cycle 2 of treatment and received 300 mg at Week 1 and 2000 mg during Weeks 2 through 5.
