Patients with relapsed or refractory multiple myeloma (RRMM) represent an unmet clinical need. Belantamab mafodotin (belamaf; GSK2857916) is a first-in-class antibody-drug conjugate (ADC; immunoconjugate) that delivers cytotoxic payload, monomethyl auristatin F (MMAF), to cells. In the phase II DREAMM-2 study (NCT03525678), single-agent belamaf (2.5 mg/kg) demonstrated clinically meaningful anti-myeloma activity (overall response rate 32%) in patients heavily pretreated disease....
Abstract Belantamab mafodotin (belamaf) demonstrated deep and durable responses in patients with heavily pretreated relapsed or refractory multiple myeloma (RRMM) DREAMM-2 (NCT03525678). Corneal events, specifically keratopathy (including superficial punctate and/or microcyst-like epithelial changes (MECs), eye examination findings with/without symptoms), were common, consistent reports from other antibody–drug conjugates. Given the novel nature of corneal events RRMM management, guidelines...
