SAN DIEGO, CA, August 13, 2025 – Dermata Therapeutics, Inc.

“We are very excited to have received the full data set from our Phase 3 STAR-1 trial of XYNGARI™ showing that XYNGARI™ achieved statistically significant results for its three co-primary endpoints at weeks 4 and 12,” commented Gerry Proehl, Dermata’s Chairman, President, and Chief Executive Officer. “We believe these data show that not only does XYNGARI™ work after the FDA required 12-week primary endpoint, but it also works as early as week four, which was the earliest measured timepoint. We strongly believe if consumers are able to gain access to our Spongilla technology acne patients will experience the many unique benefits our product candidate can offer, and our team continues to work hard to make this happen,” concluded Mr. Proehl.

Second Quarter 2025 Financial Results

As of June 30, 2025, the Company had $6.5 million in cash and cash equivalents, compared to $3.2 million as of December 31, 2024. The $3.3 million increase in cash and cash equivalents for the six months ended June 30, 2025, resulted from approximately $7.9 million of net financing proceeds offset by $4.6 million of cash used in operations. The Company expects its current cash resources to be sufficient to fund operations into the second quarter of 2026.

Research and development expenses were $0.6 million for the quarter ended June 30, 2025, compared to $2.0 million for the quarter ended June 30, 2024. The $1.4 million decrease in research and development expenses was primarily the result of $1.6 million of decreased clinical expenses from the XYNGARI™ STAR-1 acne study, which topline data results were announced in March 2025, partially offset by $0.1 million of increased chemistry, manufacturing, and controls, or CMC, expenses and $0.1 million of increased personnel costs.

General and administrative expenses were $1.2 million for the quarter ended June 30, 2025, compared to $0.9 million for the same period in 2024. The $0.3 million increase in general and administrative expenses resulted from $0.2 million of increased public company compliance costs as well as $0.1 million of increased personnel costs.
