FOR IMMEDIATE RELEASE

From the Society for Immunotherapy of Cancer
In cooperation with the Food and Drug Administration (FDA), and as a service to our members, SITC will periodically distribute information about newly approved therapies for cancer patients. This helps FDA inform oncologists and professionals in oncology-related fields of recent approvals in a timely manner. Included in the email from the FDA will be a link to the product label, which will provide the relevant clinical information on the indication, contraindications, dosing, and safety. In sending this information, SITC does not endorse any product or therapy and does not take any position on the safety or efficacy of the product or therapy described. The following is a message from the Director of the FDA Oncology Center of Excellence, Dr. Richard Pazdur:
On February 22, 2017, the U.S. Food and Drug Administration approved lenalidomide (Revlimid®, Celgene Corp.) as maintenance therapy for patients with multiple myeloma following autologous stem cell transplant.
In 2006, lenalidomide, an orally administered thalidomide analogue, received FDA approval for use with dexamethasone in patients with multiple myeloma who received at least one prior therapy. In 2015, the indication was expanded for use in combination with dexamethasone for the treatment of patients with multiple myeloma, to include newly diagnosed multiple myeloma patients who are not eligible for autologous stem cell transplant. Lenalidomide is also approved in myelodysplastic syndromes and mantle cell lymphoma.
The current approval was based on two randomized, controlled trials evaluating the efficacy and safety of lenalidomide maintenance therapy for the treatment of multiple myeloma patients after autologous stem cell transplant (CALGB 100104 and IFM 2005-02 trials). These trials demonstrated approximately a 15-month (CALGB) and 18-month (IFM) progression-free survival advantage, at the time of the primary analysis, in patients treated with lenalidomide compared with patients receiving placebo (hazard ratio (HR) in CALGB=0.38; 95% CI: 0.27, 0.54; p<0.001 and HR in IFM=0.50; 95% CI: 0.39, 0.64; p<0.001). The median overall survival was 111 and 106 months for patients treated with lenalidomide compared with 84 and 88 months for patients receiving placebo in the CALGB and IFM trials, respectively.
The types, frequency, and severity of adverse events (AEs) observed in the two trials were similar to those previously described in the product label. Neutropenia, affecting 56% of the 517 patients treated with lenalidomide in both trials, was the most frequently reported grade 3/4 AE. An increased incidence of second primary malignancies was reported among patients treated with lenalidomide compared with those receiving placebo. The lenalidomide product label notes an increase in second primary malignancies in patients with multiple myeloma treated with lenalidomide.
The recommended dose and schedule for lenalidomide is 10mg once daily continuously on days 1-28 of repeated 28-day cycles.
