Rhea-AI Summary

Dermata Therapeutics announced Phase 2 trial results for DMT310, targeting moderate-to-severe rosacea, which did not meet primary endpoints. The treatment showed a 44% reduction in inflammatory lesions, but statistical significance wasn't achieved against placebo. Dermata plans to request an End of Phase 2 meeting with the FDA for DMT310 in acne treatment in Q1 2023. Despite the rosacea results, Dermata remains optimistic about DMT310's acne potential, citing significant effects in a prior study.

SAN DIEGO, CA / ACCESSWIRE / December 5, 2022 / Dermata Therapeutics, Inc. ("Dermata" or the "Company") (Nasdaq:DRMA)(DRMAW), a clinical-stage biotechnology company focusing on the treatment of medical and aesthetic skin conditions, today announced topline results from its Phase 2 trial of once-weekly topical application of DMT310 for the treatment of moderate-to-severe rosacea. DMT310 is Dermata's lead product candidate, with both mechanical and chemical mechanisms of action, with positive Phase 2 data in moderate-to-severe acne and Phase 1b data in mild-to-moderate psoriasis.

"While the final data were not what we had hoped for, we were encouraged to see a 44% reduction in inflammatory lesion counts after just 4 treatments with DMT310, which mirrors the 45% reduction in inflammatory lesion counts we saw in our DMT310 Phase 2b acne study," stated Christopher Nardo Ph.D., Dermata's Chief Development Officer. "We believe the above average dropout rate of 23% for patients treated with DMT310 seen in this rosacea study, versus 13% seen in the Phase 2b acne study, could explain the reduced treatment effect of DMT310 at Week 12. Rosacea is a complicated skin disease that affects patients with sensitive skin and the disease waxes and wanes with environmental and physiological exposures. Some patients did achieve a meaningful change in their rosacea with 36% of DMT310 patients meeting the criteria for a responder on the Investigators Global Assessment scale at Week 12. However, DMT310 was not able to statistically separate from placebo with 23% of placebo patients meeting the criteria as a responder at Week 12," continued Dr. Nardo. "A treatment responder is defined as an IGA grade of ‘clear' or ‘almost clear' and at least a 2-grade improvement from baseline. Lastly, we want to thank the patients and investigators who participated in this study."

"While we are disappointed with the results in rosacea, we are still encouraged by DMT310's treatment potential for acne, as we have seen a highly statistically significant treatment effect in our DMT310 Phase 2b moderate-to-severe acne study on all three co-primary endpoints at Week 12," stated Gerry Proehl, Dermata's Chairman, President, and Chief Executive Officer. "We will continue to evaluate the full data set to determine DMT310's potential as a treatment for moderate-to-severe rosacea. At this time, we will focus our efforts and resources on preparing for our End of Phase 2 meeting with the FDA for DMT310 in moderate-to-severe acne and initiation of the Phase 3 acne program in 2023," continued Mr. Proehl. "With each clinical study, we learn more about this product candidate and still believe in DMT310's potential as a unique, once-weekly treatment option for acne and other inflammatory skin diseases," concluded Mr. Proehl.

About DMT310

DMT310 is Dermata's lead product candidate and incorporates the Company's proprietary Spongilla technology to topically treat a variety of dermatological skin diseases and conditions. DMT310 is a multifactorial natural product candidate derived from Spongilla lacustris, a unique freshwater sponge that is harvested under specific environmental conditions and then processed into a powder. The powder is mixed with a fluidizing agent immediately prior to its once-weekly application. In addition to its mechanical components which create microchannels into the dermis and promote skin turnover, DMT310's organic components contain chemical compounds that when tested in vitro have shown a dose dependent inhibition of inflammatory mediators, which we believe play a role in a variety of skin diseases.
