Evommune Reports Third Quarter 2025 Financial Results and Provides Business Update
- Three Phase 2 data readouts from lead programs, EVO756 and EVO301, expected in 2026 across atopic dermatitis (AD) and chronic spontaneous urticaria (CSU)
- Well capitalized to deliver on key milestones following completion of initial public offering (IPO), raising $172.5 million in gross proceeds, including the full exercise of the underwriters’ option to purchase additional shares
Palo Alto, Calif., December 11, 2025 – Evommune, Inc. (NYSE: EVMN) (the “Company”), a clinical-stage biotechnology company developing innovative therapies that target key drivers of chronic inflammatory diseases, today announced financial results for the third quarter ended September 30, 2025, and provided a business update.
“The recent completion of our IPO puts us in a strong position to deliver on the years ahead, with three Phase 2 readouts across our two lead programs, EVO756 and EVO301, expected next year. Atopic dermatitis (AD) remains the most prevalent autoimmune disease, and the need for more treatment options is urgent. We’re advancing two programs targeting novel mechanisms designed to give physicians and patients new tools to treat AD, if approved. MRGPRX2 antagonism is unique in its potential to change the paradigm as the first target that modulates both mast cells and sensory neurons, and IL‑18 inhibition has the potential to become a front-line biologic target in AD,” said Luis Peña, President and Chief Executive Officer at Evommune. “We also anticipate reporting top-line Phase 2b data from the EVO756 CSU trial in the first half of 2026 and are optimistic that these data will support ongoing development in CSU, which continues to be underserved by existing treatment options and represents a significant market opportunity,” added Mr. Peña.
“Overall, we are energized by the progress and execution across our pipeline, which has broad potential for patients suffering from a range of chronic inflammatory diseases. By identifying and addressing critical gaps in the current treatment landscapes, our team is working diligently to continue to discover and add to the pipeline, with a goal of delivering therapies that provide rapid symptom relief and safe, durable resolution of underlying chronic inflammatory disease,” said Jeegar Patel, Ph.D., Chief Scientific Officer at Evommune.
Pipeline Highlights
EVO756: Potent and highly selective oral small molecule antagonist of mas-related G-protein coupled receptor X2 (MRGPRX2), a receptor predominantly found on mast cells and peripheral sensory neurons.

Presented Full Phase 2 Data in Chronic Inducible Urticaria at EADV: At the European Academy of Dermatology and Venereology (EADV) 2025 Congress in Paris, France in September 2025, the Company presented additional positive data from its Phase 2 trial of EVO756 in adults with chronic inducible urticaria (CIndU). The data highlight EVO756's differentiated mast cell dual mechanism, with responses observed as early as one week and after four weeks of oral treatment. Additionally, EVO756 was generally well-tolerated. https://ir.evommune.com/news-events/press-releases/detail/85/evommune-presents-full-phase-2-data-for-oral-mrgprx2-inhibitor-evo756-in-chronic-inducible-urticaria-during-late-breaker-at-eadv-2025-congress
