The noninterventional, retrospective ALFA study assessed the real-world safety and efficacy of belantamab mafodotin, a B-cell maturation agent (BCMA)-targeted antibody–drug conjugate, in adult patients with relapsed/refractory multiple myeloma (RRMM).1 The study included 184 patients treated with belantamab mafodotin monotherapy in 45 centers in France from April 2020 to June 2021. Results were published in the European Journal of Haematology by Roussel et al.1

Key learnings:

The overall response rate was 32.7%, with 20.4% and 12.3% of patients achieving at least a very good partial response (≥VGPR) and partial response, respectively, consistent with clinical trial data. Response rates were consistent across subgroups.

Median progression-free survival (PFS) and overall survival (OS) were 2.4 months and 8.8 months, respectively. Notably, patients who responded to treatment had significantly improved survival outcomes, with a median PFS and OS of 20.6 months and not reached, respectively, in patients achieving ≥VGPR, underscoring the importance of response depth in patient outcomes.

The safety profile highlighted that 86.4% of patients experienced adverse events (AEs), primarily ocular (56.0%), including keratopathy (41.8%), which was manageable with appropriate ophthalmological monitoring and interventions.

These findings affirm that belantamab mafodotin can be effectively and safely used in routine clinical practice in a broad range of patients with RRMM, irrespective of their characteristics, though careful management of ocular AEs is necessary.
