Lenalidomide
In the randomized phase 2 SPRINT study, patients received either single-agent lenolidamine or the investigator’s choice of single-agent rituximab, gemcitabine, fludarabine, chlorambucil, or cytarabine.
The expected OR rate in 170 patients treated with lenalidomide was 40% versus 11% in 84 patients treated with investigator’s choice of treatment, and the respective CR rates were 5% and 0% (Lancet Oncol. 2016 Mar 1;17(3):319-31).
Median DOR was 16 months versus 10.4 months, PFS was 8.7 versus 5.2 months, and median OS was 27.9 versus 21.1 months in the groups, respectively.
Other options
Combination regimens, such as R-CHOP and R-bendamustine, are also options for the treatment of relapsed MCL patients who haven’t received combination therapy in the past, Dr. Blum said. Transplant is another option in some patients.
“I will consider transplants for younger patients if they come to me and they actually hadn’t had one in [their] first CR,” she said.
