Azitra, Inc. Announces Full Year 2025 Results and Provides Business Updates

BRANFORD, Conn., Feb. 27, 2026 /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 full year ended December 31, 2025, and provided a business update.

FY 2025 and Recent Business Highlights

• Initiated Phase 1/2 Trial for ATR-04 program targeting oncology patients with EGFRi-associated rash; presented ATR-04 trial design and update at ASCO 2025
• Announced positive preclinical data for ATR-01 program, targeting the treatment of ichthyosis vulgaris
• Reported promising safety data from Phase 1b Trial of ATR12 in Netherton Syndrome
• Completed financings of $8.5 million through private placements, follow-on financings and utilization of an equity line of credit.

"2025 was an exciting year for Azitra as we continued our work to revolutionize the treatment of dermatological diseases with our pipeline of first-in-class, engineered products delivered using topical live biotherapeutics," said Francisco Salva, CEO of Azitra. "A key highlight in 2025 was the progress made in our Phase 1/2 trial for ATR-04 targeting oncology patients with EGFRi-associated rash and the dosing of the trial's first patient. We were thrilled to have the opportunity to present this technology and the trial design to leaders in the field at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, where we received positive feedback and encouraging interest."

"ATR-04 has previously been granted Fast Track designation from the FDA, signaling the potential for this candidate to help the approximately 150,000 people in the United States annually who are impacted by major dermatologic toxicities associated with EGFR inhibitor treatments. Though an impactful treatment for various serious cancers, EGFR inhibition can result in adverse skin reactions that can make it difficult for patients to stay on these effective therapies."

Mr. Salva added: "For our lead program, ATR-12, we continue to be encouraged by the promising safety data generated thus far in our Phase 1b trial and are optimistic that this candidate has the potential to be a life-changing innovation for people with Netherton syndrome, a rare, autosomal recessive disease, a chronic condition characterized by severe inflammation, pruritus, scaling, red, and dehydrated skin with no known cure and limited treatment options."

Mr. Salva continued: "Also in 2025, we presented positive preclinical data for our ATR-01 program targeting ichthyosis vulgaris. Impacting approximately 1.3 million in the United States with no treatment options beyond symptom management, ichthyosis vulgaris, is an autosomal semidominant genetic disorder caused by missing or abnormal filaggrin levels. The condition is characterized by generalized xerosis and fine, white to gray scales that are prominent on the abdomen, chest, and extensor surfaces of the extremities."

Mr. Salva concluded: "2026 promises to be an important year for Azitra with several anticipated milestones including topline data for both our Phase 1b study in Netherton Syndrome and the Phase 1/2 study in EGFRi-associated rash. We also look forward to completing IND-enabling studies for ATR-01. We remain excited and optimistic as we work towards these key events, which we believe can help build significant value for our shareholders in 2026, while we progress innovative and potentially transformative treatments for patients with severe and life-altering dermatological conditions."

Azitra, Inc. is a clinical stage biopharmaceutical company focused on developing innovative therapies for precision dermatology. Azitra's lead program, ATR-12, uses an engineered strain of S. epidermidis designed to treat Netherton syndrome, a rare, chronic skin disease with no approved treatment options. Netherton syndrome may be fatal in infancy with those living beyond a year having profound lifelong challenges. The ATR-12 program includes a Phase 1b clinical trial in adults with Netherton syndrome. ATR-04, Azitra's additional clinical program, utilizes another engineered strain of S. epidermidis for the treatment of EGFR inhibitor ("EGFRi") associated skin toxicity; a Phase 1/2 clinical trial has been initiated for this program. Azitra has received Fast Track designation from the United States Food and Drug Administration for this program to treat EGFRi associated rash, which impacts approximately 150,000 people in the United States. The ATR-12 and ATR-04 programs were developed from Azitra's proprietary platform of engineered proteins and topical live biotherapeutic products that includes a microbial library comprised of approximately 1,500 bacterial strains. The platform is augmented by artificial intelligence and machine learning technology that analyzes, predicts, and helps screen the library of strains for drug like molecules.
