Bispecifics/BITE Understanding

Bispecifics/BITE Overview

Bispecific antibodies (also known as T cell engagers) are a type of immunotherapy that help the immune system to recognise and kill cancer cells. There are several bispecific antibodies for myeloma at different stages of development. Bispecific antibodies are produced in a laboratory and they are specifically created to bind to proteins on two different types of cells – myeloma cells and a person’s own T cells.

Further details related to country-based variations are provided in the report.

Bispecifics/BITE Market Outlook

Bispecific antibodies are essentially antibodies bioengineered to contain two distinct antigen-binding domains, which allow these recombinant molecules to bind specifically to more than one target. Bispecific antibodies have gained momentum over the past decade. Despite promising progress in the clinical application field of bispecific immunomodulatory antibodies in part of human tumor types, more prominent anti-tumor efficacy in most solid tumors still needs constant exploration. Furthermore, dozens of bispecific antibodies with different target combinations have exhibited potent anti-tumor effects in preclinical studies, but most of the positive preclinical outcomes could not be further validated in the clinic. With increasingly diverse bispecific antibodies entering preclinical and clinical trials, various challenges have emerged hampering the development of bispecific antibodies.

While T cell-engaging bispecific antibodies effectively treat hematological malignancies, similar strategies have not been as successful with solid tumors. Several factors are thought to contribute to T cell engagers' lower efficacy in solid tumors, including the reduced availability of ideal tumor-specific targets, immunosuppressive nature of the tumor microenvironment, and tumor physical barriers reducing antibody access.

Several key players, including Aurigene Oncology, Curis, I-MAB Biopharma, ABL Bio, Bristol Myers Squibb, IMBiologics, Y-Biologics, HK Innoen, Regeneron Pharmaceuticals, Sanofi, Zenas BioPharma, and others, are involved in developing drugs for Bispecifics/BITE for various indications such as NSCLC, Bladder and Kidney Cancers, IgG4-RD, RMS, SLE, multiple sclerosis, and others.
