Abstract

Systemic light chain (AL) amyloidosis is a relapsing plasma cell disorder. Therapy is limited, particularly for triple-class refractory disease. We report the use of belantamab mafodotin, a BCMA-directed drug–antibody conjugate, for relapsed AL amyloidosis, including patients traditionally excluded from clinical trials. Thirty-one patients were reviewed, with a median of three prior lines of therapy. The median follow-up was 12 months (95% CI 4–19), and a median of five doses were delivered. The best haematological overall response rate was 71%, and the complete/very good partial response was 58%. Sixty-eight percent had keratopathy and improved in all. Belantamab mafodotin has high efficacy and good tolerability in patients with relapsed AL amyloidosis.
