Regeneron Pharmaceuticals Announces Collaboration with Sonoma Biotherapeutics

Wednesday, March 29, 2023

Regeneron Pharmaceuticals and Sonoma Biotherapeutics announced a collaboration to apply their scientific and clinical expertise and respective technology platforms to the discovery, development and commercialisation of novel regulatory T cell (Treg) therapies for autoimmune diseases. The collaboration will bring together Regeneron’s industry-leading VelociSuite® technologies for the discovery and characterisation of fully human antibodies and T cell receptors (TCRs) with Sonoma Biotherapeutics’ pioneering approach to developing and manufacturing gene-modified Treg cell therapies.  

Under the terms of the agreement, Sonoma Biotherapeutics will receive $75 million in upfront payments, which includes a $30 million equity investment in Sonoma by Regeneron. Sonoma is also eligible to receive a $45 million development milestone payment. Regeneron and Sonoma will jointly research and develop Treg cell therapies for ulcerative colitis, Crohn’s disease and two other undisclosed indications, with a Regeneron option for a fifth indication.

This collaboration will combine Regeneron’s proven technology and clinical expertise with Sonoma Bio’s proprietary Treg platform and Treg research enterprise to develop therapies that restore balance to the immune system and potentially cure disease.
