Understanding Infection Risk with Anti-BCMA Bispecific Antibodies

Summary: Lancman and colleagues find that infection risk in patients treated with anti-BCMA bispecific antibodies for relapsed/refractory multiple myeloma is associated with severe immunoglobulin deficiency and may be mitigated by immunoglobulin replacement therapy. The study has implications for managing infection risk and raises questions about the optimal duration of treatment with these potent, novel immunotherapies.
