Research we fund

Mantle cell lymphoma (MCL) is an aggressive B-cell lymphoma characterized by resistance to standard treatments and short survival. For the 2023 LLS MCLII Synergistic Team Award, we have assembled a team of leaders in basic, translational, and clinical research in MCL to tackle the current significant obstacles in understanding and treating MCL. In the last decade, we investigated the therapy resistance mechanism of MCL, and pioneered clinical trials for targeted therapies (ibrutinib, lenalidomide) and chimeric antigen receptor T-cell (CAR-T) therapy. However, despite these dramatic advancements, resistance to these newer therapies, including targeted therapy and CAR-T cells, is seen in over 50% of patients. Thus, it remains an unmet need to better define the mechanisms of resistance and then develop rationally designed strategies to overcome resistance. The overall goal of this Synergistic Team Award is to develop improved curative therapies for patients with MCL at relapse. The goals will be addressed in three highly focused, independent but highly integrated projects that utilize state-of-the-art genomic technologies, patient-derived xenograft models, clinical data and primary MCL samples. With the joint effort of our laboratories, highly interactive and accomplished scientists, and physician researchers from multiple institutions with expertise in MCL and therapy, we are uniquely poised to develop improved next-generation of combination therapy for relapsed MCL patients.

Most patients respond well to drugs that inhibit an important MCL target named BTK. However, almost all of them will eventually relapse and then do very poorly. Inhibition of MALT1, a target which is biochemically downstream of BTK, may rescue many of these patients, and inhibiting both BTK and MALT1 may be better still. Developing a drug that inhibits both targets at the same time, from the beginning of treatment, will avoid some complications and likely be best of all; we will find out.
