Pivotal DREAMM-2 study: Single-agent belantamab mafodotin (GSK2857916) in patients with relapsed/refractory multiple myeloma (RRMM) refractory to proteasome inhibitors (PIs), immunomodulatory agents, and refractory and/or intolerant to anti-CD38 monoclonal antibodies (mAbs).

8536 Background: Single-agent belantamab mafodotin (B-cell maturation antigen targeting immunoconjugate) showed clinically meaningful activity and manageable safety in patients with heavily pre-treated RRMM (DREAMM-2, NCT03525678, Lancet Oncol.2020). We report updated results (median follow-up 9 months). Methods: DREAMM-2 is an ongoing single-agent belantamab mafodotin (2.5 or 3.4 mg/kg) study in patients with RRMM after ≥3 prior therapy lines...
