Lenalidomide Approved for Mantle Cell Lymphoma Patients by FDA

Today, June 5 the FDA approved lenalidomide capsules for the treatment of patients with mantle cell lymphoma (MCL), who have experienced relapse or progression after receiving two prior therapies including bortezomib.

According to the FDA press release:

“The approval was based a single-arm, multicenter clinical trial enrolling 134 patients with mantle cell lymphoma who have relapsed after or were refractory to bortezomib or a bortezomib-containing regimen. All 134 patients received prior treatment with bortezomib and 60% were documented to have disease refractory to bortezomib therapy. Patients received a median of 4 prior therapies for MCL. The median age was 67 years, 81% were male, 96% were Caucasian, and 61% had MCL for at least 3 years.

The efficacy endpoints were overall response rate (ORR) and duration of response (DOR). The ORR was defined as the proportion of patients whose best response was complete response (CR), complete response unconfirmed (CRu), or partial response (PR). In the 133 patients who were evaluable for efficacy, the ORR was 26% (95% CI: 18.4, 33.9). CR or CRu was achieved by 9 patients (7%) and 25 patients (19%) achieved a PR. The median DOR for the 34 patients who achieved a CR, CRu, or PR was 16.6 months (95% CI: 7.7, 26.7).”
