Abstract

Purpose

To summarize the pharmacology, efficacy, safety, dosing, administration, and pharmacist perspectives related to operationalization of new and emerging bispecific therapies indicated for the treatment of various cancers.

Summary

In recent years, there have been significant advancements in the expansion of immunotherapeutics in the treatment of various malignancies. Bispecific T cell–engaging therapies represent an emerging therapeutic drug class for the treatment of cancer. These therapies are unique antibody constructs that bind simultaneously to 2 targets, a tumor-specific antigen and CD3 on T cells, to elicit an immune response. Recently, several bispecific therapies have been approved, including epcoritamab, glofitamab, mosunetuzumab, tebentafusp, and teclistamab. Epcoritamab and glofitamab have been approved for diffuse large B cell lymphoma, while mosunetuzumab, tebentafusp, and teclistamab have been approved for follicular lymphoma, uveal melanoma, and multiple myeloma, respectively. As a result of their mechanism of action, the approved bispecific therapies have the potential to cause cytokine release syndrome, and, along with this, they all have unique and specific monitoring parameters and operational considerations that require clinician awareness when administering these therapies. Such operational challenges include within-patient dose escalations at therapy initiation, hospitalization for monitoring, and various pharmacological strategies for prophylaxis of cytokine release syndrome.

Conclusion

Bispecific therapies have continued to evolve the therapeutic landscape of cancer, primarily in hematological malignancies. Health-system pharmacists have the opportunity to play a key role in the operationalization and management of this new and emerging drug class.
