SAN DIEGO, CA / ACCESS Newswire / July 8, 2025 / Dermata Therapeutics, Inc. (NASDAQ: DRMA)(NASDAQ: DRMAW) ("Dermata" or the "Company"), a late-stage biotechnology company focusing on the treatment of medical skin diseases and aesthetic applications, today announced the Australian Patent Office has granted its patent application for its DMT410 program for the treatment of hyperhidrosis. The patent, entitled "Compositions for the treatment of skin conditions," (Australian Patent No. 2109284621) continues to strengthen Dermata's global intellectual property portfolio for DMT410 for the treatment of hyperhidrosis.

"We are thrilled to be granted this Australian patent, a testament to our team's relentless innovation and dedication to providing patients with unique and novel treatment options," said Gerry Proehl, Dermata's Chairman, President, and CEO. "We believe this patent reinforces our commitment to pushing boundaries for standard of care for hyperhidrosis patients and delivering groundbreaking solutions that we believe can transform the lives of patients. We are excited about the opportunities the DMT410 program can bring to patients, not only for the treatment of axillary hyperhidrosis, as we have seen in our proof-of-concept study, but potentially for palmer and plantar hyperhidrosis, which remain high unmet needs for patients," Mr. Proehl added.

About DMT410

DMT410 is the Company's combination treatment regimen that uses the unique mechanical features of the Company's XYNGARI™ product candidate to facilitate the intradermal delivery of botulinum toxin by topical application rather than through multiple injections with a needle. The treatment consists of an initial topical application of XYNGARI™ to the treatment area where the microscopic spicules penetrate the stratum corneum to create microchannels into the dermis allowing for the topical application and penetration of botulinum toxin. The Company has successfully completed proof-of-concept Phase 1 clinical trials using DMT410 in combination with BOTOX® for the treatment of primary axillary hyperhidrosis and for the treatment of multiple aesthetic skin conditions. Both studies showed promising efficacy results and appeared to be safe and well tolerated by patients. The Company is also planning to initiate a Phase 2a study of DMT410 (XYNGARI™ with DAXXIFY®) for the treatment of axillary hyperhidrosis.

About Dermata Therapeutics

Dermata's lead product candidate, XYNGARI™ (formerly DMT310), is its first product candidate being developed from its Spongilla technology platform. XYNGARI™ is a once-weekly, topical product candidate derived from a naturally sourced freshwater sponge with multiple unique mechanisms of action that recently achieved positive data in a Phase 3 STAR-1 study for the treatment of moderate-to-severe acne. In addition to acne, XYNGARI™ has been studied for the treatment of psoriasis and rosacea. Dermata's second program, DMT410, uses XYNGARI™ as a new method for needle-free intradermal delivery of botulinum toxin for the treatment of multiple aesthetic and medical skin diseases and conditions.
