SAN DIEGO, CA / ACCESSWIRE / November 10, 2022 / Dermata Therapeutics, Inc. (Nasdaq:DRMA;DRMAW) ("Dermata," or the "Company"), a clinical-stage biopharmaceutical company focusing on the treatment of medical and aesthetic skin conditions, today highlighted recent corporate progress, and reported financial results for the quarter ended September 30, 2022.

"I am thrilled with all that Dermata has accomplished so far this year and plan to continue the momentum as we near the announcement of our DMT310 Phase 2 topline results in patients with moderate-to-severe rosacea," said Gerry Proehl, Dermata's Chairman, President, and Chief Executive Officer. "We believe DMT310 as a once-weekly topical product candidate has the potential to change the treatment paradigm for acne and rosacea patients. We believe we can demonstrate this change by replicating the excellent results we saw in our DMT310 Phase 2b acne study in our DMT310 Phase 3 clinical program for the treatment of moderate-to-severe acne. Additionally, we look forward our continued partnering discussions for DMT410 to provide patients with more innovative treatment options."

Anticipated Upcoming Milestones

• DMT310 Phase 2 topline results in moderate-to-severe rosacea. Dermata expects to announce topline results from its DMT310 Phase 2 study in rosacea in December 2022. The trial was a 12-week, double-blinded, randomized, placebo-controlled study with 180 patients. The co-primary endpoints were (i) absolute reduction in inflammatory lesion count and (ii) Investigator Global Assessment ("IGA"), which was graded on a 5-point scale (0-4). To be considered an IGA responder, a patient must have at least a 2-grade reduction and a score of 0 or 1 at week 12. Upon successful results, the Company will look to request an end of Phase 2 meeting with the FDA.
• DMT310 Phase 3 program in moderate-to-severe acne. Dermata plans to request an end of Phase 2 meeting with the FDA in the first half of 2023. After receiving feedback from the FDA, the Company intends to initiate the DMT310 Phase 3 acne program, which will consist of two Phase 3 studies to support the submission of a new drug application to the FDA.
