- Time frame
- From the first dose (Cycle 1 Day 1) up to 6 months after the end of the last cycle of treatment; blood collected on each dosing day, weekly up to Week 8, and every 4 weeks up to Week 24/Month 7
What was measured
Half-life (t½) is defined as the time required for the concentration of the drug in plasma to decrease to one-half of its current value. Blood samples for the quantification of ofatumumab were collected during each cycle and for up to 6 months after the end of each cycle.
Analysis population: PK Population. Data were provided for the number of participants for whom the parameter could be determined.
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.
