Vanda Pharmaceuticals and Anaptys Announce Exclusive Global License Agreement for Vanda to Develop and Commercialize Imsidolimab, an IL-36R Antagonist • Imsidolimab has successfully completed two global Phase 3 studies in Generalized Pustular Psoriasis • Vanda expects to immediately begin preparing BLA and MAA applications for the US and EU • Anaptys to receive $15 million from Vanda, comprised of a $10 million upfront payment and $5 million for existing drug supply • Anaptys to receive a 10% royalty on global net sales of imsidolimab WASHINGTON AND SAN DIEGO, Feb. 3, 2025 —Vanda Pharmaceuticals Inc. (Vanda) (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.1 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. “We are excited to add imsidolimab to Vanda’s product portfolio for rare orphan disorders, as well as explore the potential of this IL-36 signal regulator in the treatment of additional inflammatory conditions where the IL-36 homeostatic balance is dysregulated,” said Mihael H. Polymeropoulos, M.D., Vanda's President, CEO and Chairman of the Board. “Imsidolimab has great synergy with our commercial portfolio, leveraging both our rare disease expertise in the US and EU as well as the anti-inflammatory portfolio that includes Ponvory® for multiple sclerosis, psoriasis and ulcerative colitis.” GPP prevalence estimates in the general population vary considerably, between 1.76 and 124 patients per million persons worldwide.2 The majority of GPP cases are caused by genetic variants in IL36RN.3,4 Loss-of-function mutations in IL36RN are mostly missense mutations in a recessive pattern and result in unrestricted IL-36 activity.5,6
"GPP is a severely debilitating, life-threatening skin disease in need of novel therapeutic approaches,” said Johann Gudjonsson, M.D., Ph.D., Arthur C. Curtis Professor of Molecular Skin Immunology and Scholar of the Taubman Medical Research Institute, University of Michigan. "The positive Phase 3 data, demonstrating GPP patients achieved rapid disease clearance through Week 4 after a single dose of infused imsidolimab, and maintained clear to almost clear skin for at least 24 weeks, with no clinically meaningful safety signals, represents a promising new option for patients living with this disease. I’m excited imsidolimab is progressing toward a regulatory filing this year.” "Vanda is an ideal partner for imsidolimab due to their strong regulatory and commercial capabilities in the US and Europe, evidenced by successful recent launches in specialty and rare diseases, and their commitment to invest in label expansion across their therapeutic portfolio, including their growing presence in inflammatory disease," said Daniel Faga, president and chief executive officer of Anaptys. “Following our productive pre-BLA meeting with FDA in 2024, we look forward to Vanda’s BLA and MAA submissions later in 2025, with the hope that this potentially differentiated therapeutic option will be made available for patients living with GPP, a burdensome, and sometimes life-threatening skin disease.” Under the terms of the agreement, Vanda will make to Anaptys an upfront payment of $10 million and a $5 million payment for existing drug supply. Anaptys is also eligible to receive up to $35 million for future regulatory approval and sales milestones in addition to a 10% royalty on net sales. Vanda will receive an exclusive global license to develop, manufacture and commercialize imsidolimab.

Cantor Fitzgerald & Co. acted as financial advisor and Orrick, Herrington & Sutcliffe LLP served as legal counsel to Vanda. About GEMINI-1 and GEMINI-2 Studies In the 45-patient GEMINI-1 Phase 3 trial, patients were randomized 1:1:1 to receive a single infusion of 750mg intravenous (IV) imsidolimab, 300mg IV imsidolimab or placebo at Day 0. Of the patients who received a single dose of 750mg IV imsidolimab, 53% achieved a GPP Physician Global Assessment (GPPPGA) score of 0/1 (clear or almost clear skin) at Week 4 (primary endpoint), compared to 13% of the patients on placebo (p=0.0131). Of the patients who received a single dose of 300mg IV imsidolimab, 53% achieved GPPPGA 0/1 at Week 4. Sixteen GPPPGA 0/1 responder patients from GEMINI-1 were subsequently re-randomized to monthly maintenance dosing of either 200mg subcutaneous (SC) imsidolimab or placebo in the GEMINI-2 Phase 3 trial. Patients were followed for at least 24 weeks and up to a maximum of 92 weeks. Of the eight responding patients from GEMINI-1 who were re-randomized to monthly 200mg SC imsidolimab maintenance therapy, 100% maintained a GPPPGA score of 0/1 and none of them experienced a flare. Of the remaining eight responding patients from GEMINI-1 who were re-randomized to placebo, 25% maintained a GPPPGA score of 0/1 and 63% experienced a flare. Data from both trials demonstrated a consistent, favorable safety and tolerability profile with no treatment-related serious adverse events (SAEs) or SAEs leading to discontinuation reported in imsidolimab-treated patients. About Imsidolimab and GPP
Imsidolimab is a fully humanized IgG4 antibody that inhibits the function of the interleukin-36- receptor, or IL-36R, that is being developed for the treatment of GPP. Regulatory and patent exclusivity is expected to extend into the late 2030s. GPP is a rare, chronic, systemic autoinflammatory disease that is potentially life-threatening, if left untreated. During a GPP flare, individuals experience the sudden eruption of painful pustules. These pustules appear over large areas of the skin, accompanied by redness, severe itchiness, and dry, cracked, or scaly skin. People with GPP may also experience more general symptoms such as fever, headache, extreme tiredness, or a burning sensation on the skin. About Vanda Pharmaceuticals, Inc.
