“…A potential novel target for targeted therapy in MM is immunoglobulin-like transcript 3 (ILT3), which is an immunoreceptor tyrosine-based inhibition motif-containing receptor, with high expression on MM cells and low or absent expression in normal tissues [ 73 ]. A CD3xILT3 BsAb showed promising anti-MM activity in preclinical experiments [ 73 ].…”

Purpose of review B-cell maturation antigen (BCMA)-directed T-cell immunotherapies, such as chimeric antigen receptor T-cells (CAR T-cells) and bispecific antibodies (BsAbs) have markedly improved the survival of triple-class refractory multiple myeloma (MM). However, the majority of patients still develops disease progression, underlining the need for new agents for these patients. Recent findings Novel T-cell redirecting BsAbs targeting alternative tumor-associated antigens have shown great promise in heavily pretreated MM, including patients previously exposed to BCMA-directed therapies. This includes the G-protein-coupled receptor class 5 member D (GPRC5D)-targeting BsAbs talquetamab and forimtamig, as well as the Fc receptor-homolog 5 (FcRH5)-targeting BsAb cevostamab. Toxicity associated with these BsAbs includes cytokine-release syndrome, cytopenias, and infections. In addition, GPRC5D-targeting BsAbs are associated with specific ‘on target/off tumor’ toxicities including rash, nail disorders, and dysgeusia. Trispecifc antibodies targeting two different MM-associated antigens to prevent antigen escape are in early clinical development, as well as trispecific antibodies (TsAbs) that provide an additional co-stimulatory signal to T-cells to prevent their exhaustion. Summary Various T-cell redirecting BsAbs are in advanced stages of clinical development with promising activity and a manageable toxicity profile. Ongoing studies are evaluating combination strategies, fixed-duration treatment, and use of BsAbs in earlier lines of therapy. TsAbs hold great promise for the future.
