Trispecific antibodies represent an emerging frontier in therapeutic antibody development, offering a novel approach to treating complex disease by simultaneously targeting three distinct epitopes. This innovative technology builds upon the success of bispecific antibodies while potentially providing even greater specificity, efficacy and versatility. Although no trispecific antibodies have yet received regulatory approval, the pipeline is rapidly expanding, with numerous candidates in early phase clinical trials. This burgeoning field represents a lucrative opportunity for research and drug development, attractive significant interest from researchers and drug developers.
The primary focus of trispecific antibody development has been on oncology, where the ability to engage multiple targets simultaneously holds promise for overcoming tumor heterogeneity and resistance mechanisms. Cancer indications being explored include hematological malignancies, solid tumors, and rare and aggressive cancers with limited treatment options.
In addition to cancer, research studies have also demonstrated the potential expansion of trispecific antibodies into other therapeutic areas, including viral diseases and eye disease. Researchers are investigating their potential to neutralize multiple viral epitopes simultaneously and exploring their use in ophthalmology for conditions like diabetic macular edema and age-related macular degeneration. Preclinical development and early phase clinical trials are underway for these newer indications.

The commercial opportunity for trispecific antibodies is underpinned by several key factors, including enhanced efficacy, reduced resistance, simplified treatment regimens, and its versatility. By engaging three targets, trispecific antibodies may offer superior efficacy compared to mono- or bispecific antibodies, potentially addressing previously intractable diseases and overcoming diseases mechanisms. They could also potentially replace combination therapies, offering improved convenience and potentially reduced side effects.
In the realm of trispecific antibodies, biotechnology and pharmaceutical companies have increased their research efforts, partnerships, and acquisitions. For example, in March 2024, Gilead and Merus announced a research partnership, option, and license agreement to identify novel dual tumor-associated antigens (TAA) to be used as targets for trispecific antibodies. Gilead and Merus agreed to collaborate to perform preclinical research and develop several separate therapeutics using Merus’ patented Triclonics® platform and Gilead’s oncology expertise.
Furthermore, it was announced in May 2024 that Merck and Eyebiotech (EyeBio) had achieved a formal agreement under which Merck will acquire EyeBio through a subsidiary. as a result, Merck’s pipeline now includes RestoretTM (EYE103), an investigational tetravalent, trispecific antibody that operates as an agonist of the Wingless-related integration site (Wnt) signaling pathway. Restoret is now undertaking a Phase 1b/2a clinical trial to treat diabetic macular edema (DME) and neovascular age-related macular degeneration (NVAMD). It is expected to enter a major Phase 2b/3 trial to investigate its efficacy for the treatment of DME patients in the second half of 2024.
With a robust research and development landscape, the domain also offers opportunities to explore. Key area of research and development of trispecific antibodies include enhancing T cell engagement, improving tumor penetration, developing predictive biomarkers, and exploring novel target combinations. Researchers are working to develop stable, manufacturable trispecific antibody format, design antibodies that can better penetrate solid tumors, and identify biomarkers that can predict response to therapy.
In conclusion, trispecific antibodies offer represent a highly promising and potentially lucrative opportunity for research and drug development. With their ability to simultaneously engage multiple targets, these innovative therapeutics offer the potential to address complex diseases more effectively than existing approaches. While challenges remain, the expanding pipeline, increasing collaborations and acquisitions, and potential for application across multiple therapeutic areas position trispecific antibodies as an exciting frontier in the biopharmaceutical industry.
