Key clinical point: Front-line chemo-free combination therapy with rituximab and lenalidomide was moderately active in elderly frail patients with diffuse large B-cell lymphoma (DLBCL) who were ineligible for conventional cytotoxic therapy.
Major finding: The overall response rate was 50.8% (95% CI 38.1%-63.4%), with 27.7% of patients achieving a complete response. After a 24-month median follow-up, the median progression-free survival was 14.0 months (95% CI 6.8-not reached) and the 2-year duration of response rate was 64.6% (95% CI 42.1%-80.1%). The grade ≥3 extra-hematological toxicity event rate was 52.3%.
Study details: Findings are from the prospective phase 2 FIL_ReRi trial including 65 frail patients aged ≥70 years with untreated DLBCL who received ≤6 cycles of lenalidomide+rituximab; patients with partial or complete response at cycle 6 received lenalidomide for 12 cycles or until progression or unacceptable toxicity.
