PURPOSE OF REVIEW: Bispecific T-cell engager (TCE) therapies are revolutionising the treatment of several haematological malignancies, including B-cell acute lymphoblastic leukaemia, various subtypes of B-cell non-Hodgkin lymphoma, and multiple myeloma. Due to their unique mode of action in activating endogenous T cells, they are associated with several important early side effects, including cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome. In addition, TCEs can cause target-specific toxicities and carry a significant risk of infection.
RECENT FINDINGS: Currently, supportive care measures for TCEs have largely been inferred from other T-cell therapies, such as CAR-T (chimeric antigen receptor) therapy. Further research into TCE-specific supportive care measures is needed to improve the tolerability of these therapies for patients. A key question moving forward is understanding how to predict and minimise early toxicity (cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome). Associated infection risk is a significant cause of patient morbidity, therefore a better understanding of how to optimise TCE-dosing and prophylactic measures, such as intravenous immunoglobulin and antimicrobials, will be crucial to achieving an improved balance of toxicity and efficacy. Enabling early outpatient delivery of these therapies to select patients at lower risk of toxicity may also help to improve patient experience and quality of life.
SUMMARY: Here we review up-to-date guidance and literature on existing supportive care measures for bispecific TCE therapy-related toxicities. We highlight both unique and serious side effects of TCE therapies that require improved management strategies to enable more patients to benefit from these efficacious drugs.
