Monoclonal antibodies were subbed a magic bullets in medicines and have become well-established therapeutic options for a variety of diseases. The success of monoclonal antibodies has been nothing short of spectacular, with several of these, like Keytruda, Opdivo, Humira, Enbrel and Herceptin, becoming blockbuster and earning significant income for their manufacturers. Building on this accomplishment, bispecific antibodies like Hemlibra and Blincyto appeared on the market, promising to attack two targets at the same time. This breakthrough paved the way for novel therapeutic options, particularly cancer, where targeting two separate antigens can result in targeted tumor death.


As we enter the dawn of a new era, trispecific antibodies are now taking the center stage. They have the potential to improve treatment outcomes by providing a more complete approach to disease management. As the name suggests, they target three targets at once, broadening the range of therapy options. No trispecific antibody has received regulatory approval; however, many are under clinical development. JNJ-80948543 (Janssen), PIT565 (Novartis), GB263T (Genor Biopharma) and NM21-1480 (Numab Therapeutics) are now in early-phase clinical trials.


As science progresses, the limits of possibility are pushed even further. The development of tetraspecific antibodies, which can target four separate antigens, is an important milestone in this aspect. This breakthrough has the potential to transform treatment strategies for diseases that have previously been proven difficult to cure with standard of care treatment. Like trispecific antibodies, no tetraspecific antibodies have received approval yet, but are in clinical development. The Chinese pharmaceutical company Sichuan Baili Pharmaceutical, along with its US-based subsidiary Systimmune, pioneered the development of tetraspecific antibodies. The company has three products in development, all for the treatment of solid and hematological cancers. The farthest of these has entered phase 2 clinical trials.


The new era of multispecific antibodies, which include trispecific and tetraspecific antibodies, represents a paradigm change. They enable for the simultaneous targeting of several disease causes, providing a more nuanced approach to disease management. Addressing multiple targets at once is a technique that holds immense promise of complicated diseases like cancer, where resistance mechanisms frequently evolve due to tumor heterogeneity.


The path to the era of multispecific antibodies is not without difficulties. The creation of these advanced therapeutics necessitates the use of cutting-edge technologies and platforms. For example, Merus and Cidara use their Multiclonics platform, which includes Biclonics and Triclonics, and Cloudbreak platform to create their novel multispecific antibody candidates. Similarly, Ichnos Sciences developed ISB 2001, a TREAT trispecific antibody and the first to act as a T-cell engager, based on its proprietary BEAT platform. The FDA recently granted ISB 2001 the orphan drug designation for treatment of multiple myeloma.


Moreover, collaborations between pharmaceutical companies and academic institutions are also critical for overcoming obstacles faced in developing multispecific antibodies. Partnerships can help utilize the strengths of various stakeholders, stimulating innovations and speeding up the development of multispecific antibodies.


In the same vein, investments in the development of multispecific antibodies are also crucial to the advancement of this emerging field. Developing these complicated compounds necessitated innovative research and technologies, and incorporation of interdisciplinary knowledge. Adequate financing encourages the study of novel ideas and speeds the translation of scientific discoveries into therapeutic applications. DotBio, a Singaporean biotechnological startup with an emphasis on multispecific antibodies and next-generation antibodies, announced in early August that it raised US$ 5.6 Million in a pre-Series A fundraising round. Proxima Ventures and Gaorong Capital were among the investors taking lead of this investment round.


The discovery and development of multispecific antibodies highlights the dawn of a new era in precision medicine. These emerging antibody-formats that build on the success of monoclonal and bispecific antibodies have the prospect of changing disease treatment by providing a more comprehensive and accurate approach. As partnerships and investments continue moving this field ahead, we are on the verge of revolutionary breakthroughs that have the potential to redefine the future of healthcare and enhance the lives of numerous patients across the world.
