Evommune Reports Second Quarter 2026 Financial Results and Provides Business Highlights

‑ Company to announce EVO756 atopic dermatitis (AD) Phase 2b top-line data in September 2026

‑ EVO756 migraine prophylaxis Phase 2b dose-ranging trial recently initiated with top-line data in 2027

‑ EVO301 full Phase 2a positive data set supporting planned Phase 2b trial in AD to be presented at upcoming medical conference

‑ Strong balance sheet, with cash through 2028 to deliver multiple key data readouts across the pipeline

PALO ALTO, Calif. & NEW YORK--(BUSINESS WIRE)--Evommune, Inc. (NYSE: EVMN) (“Evommune” or the “Company”), a clinical-stage biotechnology company developing innovative therapies that target key drivers of chronic inflammatory diseases, today announced financial results for the second quarter ended June 30, 2026, and provided a business update.

"There are still no first-line oral options for patients suffering with AD that combine lesion control, itch relief and tolerability. That gap is where we believe EVO756 can make a difference, as it targets neurogenic mast cell biology and non-histaminergic itch. We are excited to deliver top-line Phase 2b data next month. We also believe the underlying biology and market opportunity are especially compelling in migraine prophylaxis and that EVO756 could define the next wave of preventative treatments. We are very excited to have the Phase 2b trial now underway and expect top-line data next year,” said Luis Peña, President and Chief Executive Officer at Evommune. “Taken together, these milestones reflect the continued execution of our mission-driven approach to developing transformative therapies for people living with immune-mediated diseases."

Recent Business Highlights and Upcoming Milestones

EVO756 – Oral MRGPRX2 Antagonist Program

Potential first and best-in-class, potent and highly selective small molecule antagonist of Mas-related G protein-coupled receptor X2 (MRGPRX2), a receptor predominantly found on both mast cells and peripheral sensory neurons. This dual expression allows MRGPRX2 to uniquely modulate the neurogenic inflammation feedback loop between nerves and immune cells that drive chronic inflammation.

• Phase 2b Top-Line Data Readout in AD Expected Next Month: The Company expects to report top-line data in September 2026 for the fully-enrolled Phase 2b dose-ranging clinical trial (N=120) in moderate-to-severe AD patients. The primary endpoint of the trial is percent change in Eczema Area and Severity Index (EASI) from baseline at Week 12. Key secondary endpoints include the proportion of patients achieving ≥50% and ≥75% reductions in EASI, and evaluation of Pruritus-NRS, a tool used to assess the severity of itching.
• Migraine Prophylaxis Phase 2b Trial Now Underway with Top-Line Data Anticipated in 2027: In July 2026, the Company initiated a global randomized, double-blind, placebo-controlled Phase 2b dose-ranging clinical trial in migraine prophylaxis. Top-line data from the trial are expected in 2027. The trial is evaluating EVO756 in adults with refractory migraine experiencing ≥6 migraine days per month. Approximately 330 patients will be randomized across two active dose arms and placebo for 12 weeks of treatment. The trial is exploring daily doses of up to 100 mg. The primary endpoint of the Phase 2b trial is the mean change from baseline in monthly migraine days (MMD). Key secondary endpoints include the proportion of patients achieving ≥50% and ≥75% reductions in MMD, change from baseline in monthly headache days and monthly acute migraine medication use.
• Prioritization of EVO756 Development Outside of CSU: In June 2026, the Company reported top-line results from a randomized, double-blind, placebo controlled, dose-ranging Phase 2b trial in adults with moderate-to-severe chronic spontaneous urticaria (CSU). The study did not meet the primary endpoint of mean change in a patient’s Urticaria Activity Score over seven days (UAS7) at 12 weeks at any dose. The safety profile observed demonstrated safe and well-tolerated doses of EVO756. Following these results, Evommune has discontinued development of EVO756 in CSU and will continue to focus development efforts on AD and migraine.

EVO301 – Injectable IL-18 Binding Protein Fusion Protein Program

Long-acting fusion protein consisting of an IL-18 binding protein and an anti-serum albumin Fab-associated domain with potential for more effective distribution to inflamed tissues than traditional monoclonal antibodies.

• Full Results from Positive Phase 2a Trial in AD to be Presented at Upcoming Medical Conference: The full dataset from the positive Phase 2a trial in adult patients with moderate-to-severe AD will be presented at an upcoming medical conference, where the Company plans disclosure on key secondary endpoints as well as key biomarker data showing Th2 and non-Th2 biomarker impact supporting the breadth of IL-18 inhibition in AD.
• Phase 2b AD Trial to Initiate in mid-2027: The planned Phase 2b, placebo-controlled, dose-ranging clinical trial is expected to include at least three subcutaneous dosing regimens of EVO301 tested over a 16-week treatment period. Manufacturing is ongoing and following completion of standard scale-up and toxicology activities, the trial is anticipated to begin in mid-2027.
• Evaluating Additional Indication Expansion Opportunities: The Company continues to evaluate additional indications for EVO301, including ulcerative colitis and certain cardiovascular-related inflammatory conditions, as potential new Phase 2 clinical trials.

Second Quarter 2026 Financial Results

• Research and Development Expenses: Research and development expenses were $26.4 million and $43.7 million for three and six months ended June 30, 2026, compared to $19.6 million and $34.0 million for the three and six months ended June 30, 2025.
