Bispecific T cell engagers offer a novel treatment approach for patients with multiple myeloma, although mechanisms of resistance are largely unknown. Here, we discuss the implications of a recent report from Friedrich et al. that highlights the importance of pre-treatment T cell characteristics for a response to the T cell engager elranatamab and how these data might be used to inform future study and trial design.
