Regeneron Ventures leads $75 million Series A for eczema-focused antibody startup Infinimmune

Aug 10, 2026·read at Fierce Biotech ↗DealPositive

Infinimmune, a Bay Area biotech developing antibody therapies for eczema, announced a $75 million Series A financing round.

The round was co-led by Regeneron Ventures and Playground Global, with participation from RA Capital Management, Forge Life Science Partners, Goldcrest Capital and existing backer Merck & Co.

Regeneron's involvement signals interest in a potential competitor to its own eczema drug Dupixet, as Infinimmune's lead candidate IFX-201 targets interleukin-13, a mechanism also used by Dupixet.

Company co-founder and CEO Wyatt McDonnell said the funding will help advance the antibody platform and develop complementary molecules for the complex, multifactorial disease.
