  Description
2000 mg Ofatumumab + DR Ofatumumab intravenous (iv) infusion was initiated at 300 milligrams (mg), followed by seven weekly 2000 mg infusions and then four monthly infusions of 2000 mg for a duration of 24 weeks. The independent endpoint review committee (IRC) classified these participants as double refractory (DR), defined as participants who were enrolled in the study and were refractory to both fludarabine and alemtuzumab.
2000 mg Ofatumumab + BFR Ofatumumab iv infusion was initiated at 300 mg, followed by seven weekly 2000 mg infusions and then four monthly infusions of 2000 mg for a duration of 24 weeks. The IRC classified these participants as bulky fludarabine refractory (BFR), defined as participants who were enrolled in the study and were refractory to fludarabine with bulky lymphadenopathy.
2000 mg Ofatumumab + Other Ofatumumab iv infusion was initiated at 300 mg, followed by seven weekly 2000 mg infusions and then four monthly infusions of 2000 mg for a duration of 24 weeks. The IRC classified these participants as "other," defined as participants who were enrolled in the study but did not meet criteria for DR or BFR.
