The combination of lenalidomide and rituximab was more active in patients with recurrent follicular lymphoma, compared with lenalidomide alone, and significantly increased the overall response rate, according to new data published online Aug. 24 in the Journal of Clinical Oncology.
Although both lenalidomide and rituximab are active agents in follicular lymphoma, their combined use in recurrent follicular lymphoma has not been previously evaluated in randomized clinical trials, said Dr. John P. Leonard of Cornell University, New York, and his colleagues.
The overall response rate of patients receiving the combination regimen was significantly higher than that of patients who received lenalidomide alone (P = .029). In the cohort receiving lenalidomide alone, 24 patients (53%) achieved an objective response (9 complete responses [20%]), while 35 patients (76%) in the lenalidomide/rituximab group were responders (18 complete responses [39%]).
At a median follow-up of 2.5 years (range, 0.1-4.8 years), the addition of rituximab to lenalidomide in this population also significantly increased the median time to progression: 1.1 year for lenalidomide alone versus 2 years for the combined therapy (P = .002).
Overall survival was 4.5 years for lenalidomide alone and has not yet been reached for the combination arm (P = .149.
This trial helps to establish the safety profile of single-agent lenalidomide in follicular lymphoma, while its “randomized nature also allows a direct assessment of potential toxicity resulting from the addition of rituximab to lenalidomide,” wrote Dr. Leonard and his associates (J Clin Oncol. 2015 Aug 24. doi: 10.1200/JCO.2014.59.9258).
“There was no evidence of increased toxicity from the lenalidomide/rituximab combination compared with lenalidomide alone,” they pointed out.
Both lenalidomide alone and lenalidomide/rituximab were well tolerated, with grade 3-4 adverse events occurring in 58% and 53% of patients, respectively, with 9% and 11% of patients experiencing grade 4 toxicity, respectively. The most common grade 3-4 adverse events included neutropenia (16% vs. 20%), fatigue (9% vs. 13%), and rash (4% vs. 4%).
The study was supported in part by grants from the National Cancer Institute to the Alliance for Clinical Trials in Oncology. Dr. Leonard reported financial relationships with Celgene and Genentech, and several coauthors also reported relationships with industry.
