Sol-Gel Technologies (NASDAQ: SLGL), (“Sol-Gel”), today announced positive topline data for its open-label, long-term safety study, evaluating Epsolay®, microencapsulated benzoyl peroxide cream, 5%, in papulopustular rosacea for a treatment duration up to 52 weeks.
NESS ZIONNA, Israel, Feb. 13, 2020 (GLOBE NEWSWIRE) -- Sol-Gel Technologies (NASDAQ: SLGL), (“Sol-Gel”), today announced positive topline data for its open-label, long-term safety study, evaluating Epsolay®, microencapsulated benzoyl peroxide cream, 5%, in papulopustular rosacea for a treatment duration up to 52 weeks.
The study enrolled 547 subjects, all of whom had completed 12 weeks of treatment with Epsolay or vehicle in the preceding double-blind Phase 3 studies. Patients continued onto open-label treatment with Epsolay once-daily for up to an additional 40 weeks. The safety population of 535 subjects received Epsolay therapy for an overall period of at least 28 weeks. Of these 535 subjects, 209 subjects completed 52 weeks of treatment with Epsolay, exceeding the sample size requirements previously defined by the FDA for the one-year safety evaluation.
Non-cutaneous adverse events were similar in frequency and type to those observed in the preceding Phase 3 trials. The most common adverse event reported was nasopharyngitis (5.4%). Less than 3% of patients experienced application site adverse events that were considered to be drug-related, and no serious drug-related adverse events were reported.
At every study visit, the investigator conducted Local Tolerability and Cutaneous Safety Assessments. At the end of 52 weeks more than 90% of subjects had “none” or “mild” signs or symptoms (burning or stinging, itching, dryness and scaling) and no “severe” tolerability scores were recorded.
Although the study was designed to evaluate long-term safety, subjects also continued to undergo evaluation according to the Investigator Global Assessment (IGA) 5-point scale. Of the 209 patients treated with Epsolay for 52 weeks, 73.2% reported a score of 0 (“clear”) or 1 (“almost clear”) at 52 weeks.
“We are very pleased that these long-term use results further support and strengthen the positive safety and tolerability data we previously observed in our Phase 3 program for Epsolay,” said Alon Seri-Levy, Sol-Gel’s Chief Executive Officer. “It is our hope that this data can provide patients, seeking long term control of their chronic condition, the confidence in a treatment that has demonstrated a favorable safety and tolerability profile. We believe these results will complete the data required to finalize our NDA submission, which is planned for the second quarter of this year.”
About Epsolay
Epsolay is an innovative topical cream containing encapsulated benzoyl peroxide, 5%, that Sol-Gel is developing for the treatment of inflammatory lesion of rosacea (Papulopustular Rosacea). Epsolay, if approved, is intended to be applied to the face once a day. Sol-Gel uses a patented process to encapsulate benzoyl peroxide in silica-based microcapsules. The silica shell is aimed to serve as a barrier between the benzoyl peroxide and the epidermis, reducing the ability of the benzoyl peroxide to induce strong oxidation processes that may result in cutaneous adverse events such as erythema, burning and stinging. The slow migration of benzoyl peroxide from the microcapsules is aimed to deliver effective doses of benzoyl peroxide onto the skin, while the barrier improves the tolerability of benzoyl peroxide. Silica is chemically inert, photochemically and physically stable, and safe for topical use. If approved, Epsolay has the potential to be the first FDA-approved single-active benzoyl peroxide prescription drug product.
About Papulopustular Rosacea
Papulopustular rosacea also known as inflammatory lesion of rosacea, is a chronic and recurrent inflammatory skin disorder that affects nearly 5 million Americans. The condition is common, especially in fair-skinned people of Celtic and northern European heritage. Onset is usually after age 30 and typically begins as flushing and subtle redness on the cheeks, nose, chin or forehead. If left untreated, rosacea can slowly worsen over time. As the condition progresses the redness becomes more persistent, blood vessels become visible and pimples often appear. Other symptoms may include burning, stinging, dry skin, plaques and skin thickening.
