- 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
Volume of distribution at steady state (Vss) is defined as the apparent volume of distribution of the drug in the body at steady state. 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.
