This finding highlights the functional relevance of IMiD's inherent polypharmacology in circumventing primary resistance mechanisms at the cellular level. Together, our results identify the ARID2-containing PBAF complex as a critical vulnerability in resistant myeloma cells and provide a mechanistic rationale for designing combination strategies that co-target this complex, with the potential to enhance therapeutic efficacy by overcoming drug resistance.
Triplet regimens that include an immunomodulatory agent, proteasome inhibitor, and dexamethasone are widely used in newly diagnosed and relapsed/refractory (R/R) multiple myeloma (MM)...Additionally, we have compared these results with similar combinations with the immunomodulatory agent pomalidomide (POM). Our studies indicate that the MEZI/BTZ/DEX triplet is superior to all single agents and POM/BTZ/DEX in terms of potency of antiproliferative and proapoptotic activities, substrate degradation depth and kinetics in the presence of BTZ, and in vivo efficacy. We show that the combination of MEZI with BTZ increases cell death through disruption of multiple phases of the cell cycle and this thereby enhances the direct cytotoxic effects of the combination treatment.
