Systemic glucocorticoids in a dose equivalent to ≤25 mg per day of prednisone within 2 weeks before first dosing of study medication were allowed.

Although all patients were required to have lymphadenopathy for trial inclusion, documented clinical history of lymphoproliferation (eg, lymphadenopathy, splenomegaly, hepatomegaly) varied.
