  Description
2000 mg Ofatumumab + DR Participants who had responded to ofatumumab or had stable disease in Hx-CD20-406 (Study OMB111773; NCT00349349) and then progressed were offered retreatment and maintenance. For retreatment, ofatumumab intravenous (iv) infusion was initiated at 300 milligrams (mg), followed by seven weekly 2000 mg infusions. For the maintenance of responders, participants received 24 monthly infusions of 2000 mg for up to 24 months, for a total duration of treatment of up to 26 months. These participants were classified as double refractory (DR), defined as participants who were enrolled in Study Hx-CD20-406 and were refractory to both fludarabine and alemtuzumab.
2000 mg Ofatumumab + BFR Participants who had responded to ofatumumab or had stable disease in Hx-CD20-406 and then progressed were offered retreatment and maintenance. For retreatment, ofatumumab intravenous (iv) infusion was initiated at 300 milligrams (mg), followed by seven weekly 2000 mg infusions. For the maintenance of responders, participants received 24 monthly infusions of 2000 mg for up to 24 months, for a total duration of treatment of up to 26 months. These participants were classified 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 Participants who had responded to ofatumumab or had stable disease in Hx-CD20-406 and then progressed were offered retreatment and maintenance. For retreatment, ofatumumab intravenous (iv) infusion was initiated at 300 milligrams (mg), followed by seven weekly 2000 mg infusions. For the maintenance of responders, participants received 24 monthly infusions of 2000 mg for up to 24 months, for a total duration of treatment of up to 26 months. These participants were classified as "other," defined as participants who were enrolled in the study but did not meet criteria for DR or BFR.
