Boehringer Ingelheim, a global pharmaceutical leader, has secured an exclusive worldwide license from Sitryx Therapeutics for a promising preclinical small-molecule program targeting autoimmune and inflammatory diseases.
Announced on 26 February 2026, the deal positions this novel oral candidate as a potential disease-modifying therapy across multiple indications, addressing a critical gap in current treatments.
Autoimmune and inflammatory conditions, such as rheumatoid arthritis, psoriasis, and inflammatory bowel disease, affect millions worldwide and impose a growing global health burden. Existing therapies often fail to provide long-term disease control, leaving patients underserved.
Sitryx’s program introduces a precise mechanism that inhibits disease-driving pathways through immunometabolic modulation restoring immune balance without broad immunosuppression.
This approach leverages Sitryx’s expertise in translating cutting-edge immunometabolic targets into oral small-molecule candidates.
“This collaboration is a major milestone for our company and a clear validation of the strength of our pipeline and our expertise in translating immunometabolic targets into meaningful therapeutic candidates,” said Iain Kilty, CEO of Sitryx.
Boehringer Ingelheim, with its robust immunology portfolio, sees strong alignment. “Autoimmune and inflammatory diseases remain areas where innovation is urgently needed. Sitryx’s small molecule inhibitor program brings forward a promising new mechanism that aligns with our focus on advancing first-in-class approaches,” stated Carine Boustany, Head of Immunology and Respiratory Diseases Research at Boehringer.
Boehringer Ingelheim will take full responsibility for advancing the program through research, clinical trials, and commercialization.
Financial terms include upfront and near-term payments to Sitryx, plus milestone payments exceeding $500 million tied to development, regulatory approvals, and sales, alongside tiered royalties. This structure incentivizes rapid progress while validating Sitryx’s early-stage innovation.
The partnership underscores a trend in biotech-pharma alliances: big players licensing high-potential preclinical assets to accelerate pipelines amid rising demand for targeted autoimmune therapies. As Boehringer advances this program, it could yield the next breakthrough in oral, disease-modifying treatments.
