This is an open-label, two- arm, randomized phase 3, superiority trial designed to evaluate the efficacy and safety of duvelisib compared to ofatumumab administered to patients who have been diagnosed with CLL/SLL whose disease is relapsed or refractory. Approximately 150 subjects will receive a starting dose of 25 mg duvelisib BID initially over the course of 21-day treatment cycle followed by 28-day treatment cycles for up to 18 cycles or until disease progression or unacceptable toxicity (whichever comes first). After 18 complete cycles of treatment, subjects may receive additional cycles of duvelisib until disease progression or unacceptable toxicity if they, in the judgment of the Investigator, may derive benefit from continued treatment, and if the subject meets the criteria for additional treatment at Cycle 19 Day 1. Approximately 150 subjects will receive a starting dose of 300 mg ofatumumab on Day 1 followed by seven weekly doses of 2000 mg. Thereafter, subjects will receive 2000 mg ofatumumab once every month for four months. Administration of ofatumumab will not exceed the 12 doses (within 7 cycles).
