OPKO Health's ModeX Therapeutics Enters into Research Collaboration with Regeneron to Develop Multispecific Antibodies for Select Therapeutic Indications
- Potential assets would target multiple biological pathways in a single molecule
- Total value of the partnership potentially exceeds $1 billion if multiple assets advance
WESTON, Mass., Oct. 29, 2025 (GLOBE NEWSWIRE) -- ModeX Therapeutics Inc., an OPKO Health company (NASDAQ:OPK), today announced that it has entered into a license and collaboration agreement with Regeneron Pharmaceuticals Inc. (NASDAQ:REGN) to discover and develop multispecific antibodies for several therapeutic indications of mutual interest. The collaboration will apply ModeX's MSTAR platform and Regeneron's proprietary binders to develop multispecific antibody candidates that target multiple distinct biological pathways in a single molecule.
Under the terms of the agreement, ModeX will receive an upfront payment of USD $7 million, and potential future product selection payments, clinical and regulatory milestone payments, and commercial milestone payments exceeding USD $200 million per selected molecule. The overall value of the collaboration potentially exceeds $1 billion if multiple products from the collaboration are successful. In addition, ModeX is eligible to receive tiered global net sales royalties, up to low double digits at the highest tier. Regeneron will fund and lead any preclinical, clinical development and commercialization activities for any products it elects to advance.
"This agreement allows us to work closely with Regeneron, world leaders in the development of antibody medicines, to explore the promise of multispecific antibodies in new indications, including immunology, oncology and metabolic diseases. ModeX's mission is to develop innovative antibodies that recognize multiple targets in a single molecule to treat life-threatening diseases," said Gary Nabel, M.D., Ph.D., President and Chief Executive Officer of ModeX and Chief Innovation Officer of OPKO Health.
"We have dramatically expanded the therapeutic potential of antibodies through our MSTAR platform. Our antibody candidates are already in clinical trials, providing unique disease target combinations and reliable manufacturing," said Elias Zerhouni, M.D., President and Vice Chairman of OPKO. "We believe this collaboration, with Regeneron's outstanding team, will advance the development of multispecific antibodies across a spectrum of chosen indications in several disease areas of high interest to both parties."
"Like Regeneron, ModeX has a team of scientist entrepreneurs who think creatively about science and technology," said George D. Yancopoluos, M.D., Ph.D., Board Co-Chair, President and Chief Scientific Officer of Regeneron. "By pairing Regeneron's expertise in drug development with ModeX's platform for multispecific antibodies, we are building on Regeneron's longstanding work in bi-and multi-specific antibodies and increasing our shots on goal by identifying more candidates faster to potentially help patients across multiple disease categories."
Beyond bispecifics: ModeX Synergistic Targeting of Antibody Receptors (MSTAR)
Multispecific antibody therapeutics can help generate medicines of the future by targeting three or more disease pathways simultaneously. Many untreatable or complex conditions arise from multiple disease pathways; yet, most medicines only act on a single target. ModeX overcomes these challenges by combining natural protein structures using a platform known as the ModeX Synergistic Targeting of Antibody Receptors (MSTAR) to create unique multispecific medicines. The platform generates multispecific antibodies from modular building blocks intended to modulate potency and maximize specificity to address multiple disease pathways simultaneously.
