• STAR-1 topline results expected in first quarter of 2025 
• About 30 million acne patients seek treatment in the U.S. each year 
• DMT310, if approved, could be the first once-weekly topical product for the treatment of acne 

SAN DIEGO, CA / ACCESSWIRE / July 17, 2024 / Dermata Therapeutics, Inc. (Nasdaq:DRMA)(Nasdaq:DRMAW) ("Dermata" or the "Company"), a late-stage biotechnology company focusing on the treatment of medical and aesthetic skin conditions, today announced that it has successfully enrolled 50% of patients in its pivotal Phase 3 Spongilla Treatment for Acne Research (STAR-1) study of DMT310, a novel, once-weekly, topical product candidate for the treatment of moderate-to-severe acne. The STAR-1 study is the first of two Phase 3 studies that, if positive, would be used by the Company to support the filing of a new drug application (NDA) for DMT310 for the treatment of moderate-to-severe acne.

"We are excited by the enrollment progress seen in the STAR-1 study since enrolling our first patient in December 2023 and want to thank all those patients for their participation in the study," said Christopher Nardo, Ph.D., Dermata's Chief Development Officer. "With all clinical sites activated, we expect to continue our enrollment momentum in the coming months and expect to announce topline data from the STAR-1 study in the first quarter of 2025," Dr. Nardo continued. "Investigators continue to be enthusiastic about DMT310 and its potential to be the first approved once-weekly, topical product for the treatment of moderate-to-severe acne as there continues to be a need for safe and effective treatment options. We believe that if the DMT310 Phase 3 program confirms the safety and efficacy observed in our Phase 2b acne study, that if approved, DMT310 could become a first line therapy for the treatment of moderate-to-severe acne," concluded Dr. Nardo.

DMT310 Phase 3 Clinical Program Design

The DMT310 Phase 3 clinical program will include two Phase 3 clinical trials to evaluate the efficacy, safety, and tolerability of DMT310 in patients with moderate-to-severe facial acne. Each Phase 3 trial will be randomized (2:1), double-blind, and placebo-controlled, enrolling approximately 550 patients with moderate-to-severe acne, ages 9 years and older in the United States and Latin America. The primary endpoints are the mean change from baseline in inflammatory and noninflammatory lesion counts and the Investigator Global Assessment (IGA) treatment response. IGA is measured on a 5-point scale (0-4), with a treatment response defined as at least a 2-point improvement from baseline and an IGA score of 0 (clear) or 1 (almost clear). Patients will be treated once a week for 12 weeks with either DMT310 or placebo and will be evaluated monthly. STAR-1 is the first of two pivotal Phase 3 trials, of which the second Phase 3 study will be followed by a long-term extension study. If positive, the results from the Phase 3 program would be used to support the filing of an NDA with FDA.

About DMT310

DMT310 is a novel, once-weekly, topical product candidate derived from a freshwater sponge being developed for the treatment of multiple skin diseases. DMT310 has multiple mechanisms of action that include mechanical components and chemical compounds to help treat inflammatory skin diseases, like acne. After processing, the sponge powder contains precisely sized and shaped silica spicules that upon application may help exfoliate the skin, promote collagen production, open closed comedones (creating an aerobic environment to help kill C. acne bacteria), and create microchannels to facilitate penetration of the sponge's naturally occurring chemical compounds. These chemical compounds have been shown, in-vitro, to have both antimicrobial and anti-inflammatory properties, which may play a significant role in the treatment of inflammatory skin diseases. DMT310 has previously shown its treatment effect in moderate-to-severe acne in a Phase 2b study where DMT310 applied once weekly, achieved statistically significant results at all timepoints for all primary and secondary endpoints. DMT310 also observed almost 45% of patients achieve an IGA score of clear or almost clear compared with less than 18% of placebo patients achieving the same at the end of 12 weeks.

About Acne Vulgaris

Over 30 million acne patients in the U.S. seek treatment each year, with about 85% of teenagers experiencing some form of acne, and some individuals suffering from acne well into their 30s, 40s, and beyond. Acne is characterized by areas of scaly red skin, noninflammatory blackheads and whiteheads, inflammatory papules and pustules, and occasionally cysts and scarring, which can present on the face, neck, chest, back, shoulders, and upper arms. While not life-threatening, acne can cause significant trauma for those suffering from it due to social stigmas, substantial risk of permanent facial scarring, lowered self-esteem, and social withdrawal.
