SAN DIEGO, CA / ACCESSWIRE / March 28, 2022 / Dermata Therapeutics, Inc. (NASDAQ:DRMA; DRMAW) ("Dermata" or the "Company"), a clinical-stage biotechnology company focusing on the treatment of medical and aesthetic skin conditions, today highlighted recent corporate progress and reported financial results for the year ended December 31, 2021.

"We continue to make excellent progress with the clinical programs for DMT310, our once weekly topical product derived from a naturally sourced freshwater sponge. In October 2021, we announced positive results from a Phase 1b proof of concept clinical trial in mild-to-moderate psoriasis patients. In November 2021, we initiated a Phase 2 trial in moderate-to-severe rosacea patients, where we believe DMT310's anti-inflammatory properties can demonstrate a clinical effect on the inflammatory lesions of rosacea, similar to the clinical effects we have seen in our Phase 2 acne studies. We expect to complete enrollment for this Phase 2 trial in moderate-to-severe rosacea in the first half of 2022 and expect to announce topline results in the second half of 2022," commented Gerry Proehl, Dermata's Chairman, President, and Chief Executive Officer. "Additionally, we now have FDA guidance on the trials and trial designs required for an End of Phase 2 meeting with the FDA for moderate-to-severe acne, which we believe we can leverage for our other DMT310 clinical programs," concluded Mr. Proehl.

"For DMT410, our combination product with botulinum toxin Type A, we completed a Phase 1b study in facial aesthetics with demonstrated improvements in several aesthetic measures that we believe continue to have a high unmet need. Successfully delivering botulinum toxin to the dermis through topical administration has been a target for many years and we believe DMT410 has demonstrated an ability to do just that," stated Chris Nardo, Ph.D., Dermata's Senior Vice President of Development. "With a topical application of DMT410, we were able to see a reduction in the number and size of pores, a reduction in fine lines, and a reduction in sebum production. In addition, the investigator graded most patients as improved in luminosity, brightness, and overall aesthetic appearance," concluded Dr. Nardo.

Corporate Highlights

• In November 2021, Dermata initiated a DMT310 Phase 2 trial in moderate-to-severe rosacea. On November 15, 2021, the Company enrolled its first patient in a Phase 2 rosacea trial. As of March 28, 2022, the trial is more than two-thirds enrolled, with the last patient expected to be enrolled in the first half of 2022, with topline results expected in the second half of 2022. The trial is double-blinded, randomized, placebo-controlled with approximately 180 patients expected to be enrolled at 20 clinical sites in the United States. The co-primary endpoints are absolute reduction in inflammatory lesion count and Investigator Global Assessment (IGA), which will be graded on a 5-point scale (0-4). To be considered a responder, a patient needs to have at least a 2-grade reduction and an IGA score of 0 or 1.
• In November 2021, Dermata successfully completed a Phase 1b proof of concept trial of DMT410 in facial aesthetics with compelling results. In the trial, DMT410 showed a reduction in the size and number of pores and a reduction in fine lines as shown by facial photography. The Company also measured a reduction in sebum production. In addition, the clinical investigator observed improvements in luminosity, brightness, and patient's overall facial aesthetic. The Company intends to seek to partner with a botulinum toxin company prior to moving into Phase 2.
• FDA provided the Company with clarity on the trial requirements and trial designs required prior to holding an End of Phase 2 meeting with the FDA for the DMT310 Phase 3 acne studies. In February 2022, the Company received feedback from the FDA on the non-clinical studies and Pharmacokinetic study required to be completed prior to an End of Phase 2 meeting with the FDA. The Company expects to complete these required studies by the end of 2022 and request an End of Phase 2 meeting with the FDA in Q1 2023.

Anticipated Upcoming Milestones

• DMT310 Phase 2 trial in mild-to-moderate psoriasis. Based on the clinical results seen in its Phase 1b trial, the Company plans on initiating a DMT310 Phase 2 study in mild-to-moderate psoriasis in the first half of 2022, with topline results expected in the first half of 2023. The trial will be double-blinded, randomized, placebo-controlled which is anticipated to enroll approximately 150 mild-to-moderate psoriasis patients at clinical sites in the United States.
• DMT310 Phase 3 trials in moderate-to-severe acne. After the End of Phase 2 meeting with FDA planned for the first quarter of 2023, the Company plans to initiate the two Phase 3 trials in the first half of 2023. Results from these two trials are expected in the second half of 2024, with an intended filing of the NDA approximately 6 months after completion of the trials.
