The fresh $116 million haul is a far jump from the $37 million series A round Sudo collected in September 2022.
With Sanofi Ventures in tow, Sudo Biosciences has secured $116 million to advance programs in multiple sclerosis and psoriasis into the clinic.

New backers Sanofi Ventures, Citadel’s Surveyor Capital, Monograph Capital and Eventide Asset Management also joined previous investors Frazier Life Sciences and Velosity Capital for the round.
The newest funds will go toward the biotech’s Sudostigational precision tyrosine kinase 2 (TYK2) inhibitors, two of which Sudo plans to advance into clinical testing in 2024. One is a potential first-in-class brain-penetrant program designed to treat both the relapsing and progressive forms of multiple sclerosis, as well as neurodegenerative conditions such as Alzheimer’s disease and amyotrophic lateral sclerosis.
