Vanda, Anaptys Join on Development Pact

Vanda Pharmaceuticals Inc. (NASDAQ: VNDA) and AnaptysBio, Inc. (Anaptys) (NASDAQ: ANAB) today announced an exclusive, global license agreement for the development and commercialization of imsidolimab (IL-36R antagonist mAb), which has successfully completed two registration-enabling global Phase 3 trials, GEMINI-1 and GEMINI-2, evaluating the safety and efficacy of imsidolimab in patients with Generalized Pustular Psoriasis (GPP).GPP is a rare skin disorder often caused by mutations in the IL36RN gene that codes for a regulatory protein that balances the activity of the proinflammatory IL-36 family of cytokines. Dysregulation of this balance in IL-36 signaling leads to severe chronic skin inflammation with pustules and systemic symptoms which carry significant morbidity and mortality often associated with sepsis and multi-organ failure.Imsidolimab inhibits the function of the IL-36R, compensating for the deficiency of the endogenous IL-36 regulator in patients with GPP. Imsidolimab has successfully concluded its development program in GPP, including the GEMINI-1 and GEMINI-2 global Phase 3 studies.In 2025, Vanda intends to initiate and complete the technology transfer activities and will immediately begin preparing the BLA and MAA applications for the US and EU and making preparations for commercialization.Soon after Monday’s opening bell, VNDA dipped 17 cents, or 3.9%, to $4.24, while shares in ANAB gave back a dollar, or 5.6%, to $16.93.
