Radiant Biotherapeutics Emerges from Stealth Mode with $8 Million Seed Round and Two Pharma Partnerships

Breakthrough platform creating multi-valent and multi-specific biotherapeutics with broad transformative applications

Building innovative internal pipeline in oncology

TORONTO, April 25, 2023 (GLOBE NEWSWIRE) -- Radiant Biotherapeutics, a revolutionary antibody platform company developing multi-valent, multi-specific therapeutics emerged from stealth mode unveiling an $8 million seed financing and two significant pharmaceutical partnerships. The Company, based on foundational IP from the labs of Dr. Jean-Philippe Julien at The Hospital for Sick Children (SickKids) and Dr. Bebhinn Treanor at the University of Toronto, was created by Amplitude Ventures which also led the seed round along with launch partner, SickKids and additional investors Alexandria Investments, FACIT and Toronto Innovation Acceleration Partners (TIAP).

“This financing enables us to advance and validate our Multabody platform among several oncology programs with potential best-in-class profiles,” said Arthur J. Fratamico, President and Chief Executive Officer of Radiant. “We are maximizing the potential of the Multabody platform by building a pipeline of candidates in our therapeutic areas of focus and pursuing additional research collaborations outside of those areas. The interest we received from potential partners to date is significant, resulting in two undisclosed collaborations with global pharma partners.”

Radiant’s Multabody platform exploits avidity - stronger binding power - coupled with multi-specificity to deliver highly efficacious antibodies with exceptional potency extending beyond today’s antibody technologies to overcome the limitations of current approaches. This innovative platform has demonstrated the potential to deliver a new class of multi-functional biologics to tackle complex and diverse diseases, including cancer, autoimmune conditions and infectious diseases. Built on an antibody framework, the Multabody retains monoclonal antibody-like developability and pharmacokinetics, creating a truly superior next-generation therapeutic.

“Radiant’s first-of-its-kind Multabody platform has the potential to transform antibody therapeutics,” said Bharat Srinivasa, founding CEO and Principal at Amplitude Ventures. “The Radiant team is showcasing their ability to rapidly develop Multabodies – from concept to in vivo POC within six months while demonstrating superior potency and efficacy to current antibodies and leveraging existing manufacturing processes. This proprietary platform has exciting potential to also create unique therapies targeting biological pathways not amenable to current antibody approaches.”
