Positive findings from two clinical trials have been published for the immunomodulatory agent lenalidomide in patients with heavily pretreated mantle cell lymphoma, and in adults with T-cell leukaemia-lymphoma or peripheral T-cell lymphoma.
The results of the phase II MCL-002 (SPRINT) study suggest that, compared with an investigator's choice of treatment, lenalidomide 25 mg/day on days 1-21 of a 28-day cycle significantly improved progression-free survival (PFS) in patients with relapsed or refractory mantle cell lymphoma who were ineligible for intensive chemotherapy or stem cell transplantation.
After a median of 15.9 months, the 170 lenalidomide-treated patients had a median PFS of 8.7 months compared with 5.2 months in the 84 patients who were treated with single-agent rituximab, gemcitabine, fludarabine, chlorambucil or cytarabine, giving a hazard ratio (HR) of 0.61.
