Azitra, Inc. Announces Q3 2025 Results and Provides Business Updates

BRANFORD, Conn., Nov. 12, 2025 /PRNewswire/ -- Azitra, Inc. ("Azitra") (NYSE:AZTR), a clinical stage biopharmaceutical company focused on developing innovative therapies for precision dermatology, today reported financial results for the quarter ended September 30, 2025, and provided a business update.

Q3 2025 and Recent Business Highlights

• Dosed first patient in Phase 1/2 trial for ATR-04 program targeting oncology patients with EGFRi-associated rash in August 2025
• Presented positive preclinical data at BIO-Europe® for ATR-01 program, targeting the treatment of ichthyosis vulgaris
• Raised $2.8M in gross proceeds through our established equity line of credit with institutional investor Alumni Capital LP

"The third quarter of 2025 was an impactful period for Azitra as we continued to progress our live biotherapeutic programs, including dosing the first patient in our Phase 1/2 trial for ATR-04 targeting oncology patients with EGFRi-associated rash," said Francisco Salva, CEO of Azitra. "This candidate previously received Fast Track designation from the FDA as there is an incredible opportunity to help alleviate a major dermatologic toxicity associated with EGFR inhibitor treatments, which impacts approximately 150,000 people in the U.S. annually. The skin toxicity that can accompany EGFRi treatment often leads to interruption or discontinuation of the treatment, profoundly impacting patients as they seek live-saving care across a variety of cancers."

Mr. Salva added: "In addition, we were thrilled to present positive preclinical data for our ATR-01 program at BIO-Europe. ATR-01 is designed to treat ichthyosis vulgaris, an autosomal semidominant genetic disorder that impacts approximately 1.3 million people in the U.S., with no treatment options beyond symptom management. The disease is caused by missing or abnormal filaggrin levels.  Our preclinical data showed production of active, functional filaggrin delivery through human stratum corneum and repair of damage in a skin model of disease."

Mr. Salva continued: "We continue to progress our lead program, ATR-12, targeting the rare, chronic and devastating Netherton syndrome. We are optimistic that this novel approach has potential to be life-changing for these patients, in an area of severe unmet need with no approved treatment options."

Mr. Salva concluded: "The second half of 2025 has already proven to be a positive period for Azitra, and we continue to look forward to showcasing the potential of our three development programs ATR-12, ATR-04, and ATR-01. All three programs were generated from our unique, proprietary platform to deliver engineered proteins using topical live biotherapeutic products."
