Azitra, Inc. Announces Q2 2025 Results and Provides Business Updates

BRANFORD, Conn. - August 11, 2025 - Azitra, Inc. ("Azitra") (NYSE American: AZTR), a clinical stage biopharmaceutical company focused on developing innovative therapies for precision dermatology, today reported financial results for the quarter ended June 30, 2025, and provided a business update.

Q2 2025 and Recent Business Highlights

•Announced initial safety results and 50% enrollment of the Phase 1b clinical trial of the ATR-12 program in Netherton syndrome, demonstrating a promising safety profile

•Announced acceptance of poster detailing the Phase 1/2 clinical trial of the ATR-04 program in EGFR inhibitor ("EGFRi")-associated rash at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting

•Entered into a purchase agreement for up to $20 million to establish an equity line of credit in partnership with institutional investor Alumni Capital LP, to fund clinical pipeline

"The first half of 2025 was a vital period for Azitra as we hit a key milestone in our first-in-class, precision, live biotherapeutic candidates designed for major undertreated dermatological diseases," said Francisco Salva, CEO of Azitra. "For ATR-12, our lead program targeting the rare, chronic and devastating Netherton syndrome, we announced promising safety data in the first five patients dosed with ATR12-351, and we believe this novel approach has potential to be life-changing for these patients. Netherton syndrome has a high unmet need with no approved treatment options."

Mr. Salva continued: "We also announced the design of our Phase 1/2 trial with our ATR-04 program at ASCO, which is investigating a live biotherapeutic product candidate containing an isolated, naturally derived S. epidermidis strain being developed for the treatment of EGFRi-associated rash. EGFRi-associated rash is a dermatologic toxicity that often accompanies EGFRi treatments for cancer, impacting approximately 150,000 patients in the United States annually. We expect to dose the first patient in our Phase 1/2 trial in the third quarter of this year."

Mr. Salva concluded: "The remainder of 2025 is anticipated to be a milestone-rich period for Azitra during which we look forward to showcasing the potential of ATR-12 and ATR-04, as well as our unique, proprietary platform for delivering engineered proteins using topical live biotherapeutic products."

About Azitra, Inc.

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.
