On October 1, 2026, Sanofi and Regeneron announced an expansion of their longstanding antibody collaboration. The agreement adds four new long-acting, Regeneron-invented antibodies targeting interleukin-13, an IL-4xIL-13 bispecific, interleukin-4 and interleukin-4 receptor alpha.
Under the agreement, Regeneron will receive USD 1 billion upfront and may receive up to an additional USD 7 billion in development, regulatory and commercial milestone payments. The companies will share development and commercialization costs and split future profits from the potential products equally worldwide. Regeneron will lead research and development, while Sanofi will lead global commercial efforts. The existing profit-sharing agreement for Dupixent will not change.
