Radiant Biotherapeutics is a biotechnology company developing a novel antibody platform called Multabody. Radiant is based on foundational science from The Hospital for Sick Children (SickKids) and the University of Toronto. The company's proprietary Multabody platform leverages both multivalency and multi-specificity to generate highly efficacious antibodies with superior potency compared to traditional antibody platforms. These Multabodies are designed to have 24 binding sites, claiming to have a stronger and more secure hold on targets compared to conventional antibodies with only two binding sites, allowing Multabodies to potentially address targets that traditional antibodies cannot effectively engage.
Radiant's technology aims to deliver a new class of biologics that can tackle complex, heterogeneous diseases such as cancer, autoimmune conditions, and infectious diseases. The company's lead clinical candidate is 4-1BB, which was advancing toward clinical trials as of September 2024. Radiant was also developing treatments for HIV, leveraging the Multabody platform's ability to potentially destroy latent viral stores and eliminate circulating viral particles.
