Popis: | We report results of a randomized, phase III study of ofatumumab versus physicians' choice treatment in patients with bulky fludarabine-refractory chronic lymphocytic leukemia and explore extended versus standard-length ofatumumab treatment. Patients (79 ofatumumab, 43 physicians' choice) completed a median 6 (ofatumumab) or 3 (physicians' choice) months' therapy. Ofatumumab-treated patients with stable disease or better were randomized (2:1) to 6 months' extended ofatumumab treatment or observation. Although the study did not meet the primary endpoint of progression-free survival (PFS) by independent review committee (ofatumumab: 5.4 months, physicians' choice: 3.6 months; p = 0.27), median PFS by investigators was significantly longer for ofatumumab versus physicians' choice (7.0 versus 4.5 months; p = 0.003) as was time to next therapy (median 11.5 versus 6.5 months; p = 0.0004). PFS and time to next therapy were significantly longer with ofatumumab extended treatment than observation (p = 0.026 and p = 0.002, respectively; n = 37). The adverse-event profile of long-term ofatumumab administration showed no unexpected findings (Clinicaltrials.gov identifier: NCT01313689). |
