Background: Multiple myeloma (MM) cells may evade immune surveillance by suppressing immune responses through the PD-1 pathway, via upregulation of PD-L1.1Nivolumab (nivo), a PD-1 immune checkpoint inhibitor that blocks PD-L1 interaction and disrupts MM-mediated PD-1 signaling, demonstrated modest activity as monotherapy in patients (pts) with relapsed/refractory multiple myeloma (RRMM) in a phase 1b study.2 Pomalidomide, an immunomodulatory drug (IMiD), may sensitize MM cells to PD-1 blockade, and has shown efficacy with dexamethasone (Pd) for RRMM. Elotuzumab (elo), an anti-SLAMF7 monoclonal antibody, directly activates natural killer cells and facilitates antibody-dependent cell-mediated cytotoxicity. Preclinical work suggests PD-1 blockade may enhance elo efficacy3; thus nivo + Pd + elo may increase clinical benefit.
