- All co-primary endpoints achieved in both Phase 3 clinical trials
- Twyneo was well-tolerated and the majority of local skin reactions, when reported, were mild and improved over time
- Additional data to be shared during the January 8th investor conference call and webcast
NESS ZIONA, Israel, Dec. 30, 2019 (GLOBE NEWSWIRE) -- Sol-Gel Technologies, Ltd. (NASDAQ: SLGL) today announced top-line results from two pivotal Phase 3 clinical trials for Twyneo®, an investigational, combination of microencapsulated tretinoin 0.1% and microencapsulated benzoyl peroxide 3% cream, which demonstrated statistically significant improvement on all co-primary endpoints in the treatment of patients with acne vulgaris. Twyneo was also found to be well-tolerated.
The primary endpoints for both trials included: the proportion of patients who succeeded in achieving at least a two grade reduction from baseline and Clear (grade 0) or Almost Clear (grade 1) at Week 12 on a 5-point Investigator Global Assessment (IGA) scale; an absolute change from baseline in inflammatory lesion count at Week 12; and an absolute change from baseline in non-inflammatory lesion count at Week 12.
“We are excited to share these robust results which further demonstrate the potential of our microencapsulation technology to deliver first-of-its kind efficacy in a topical acne treatment,” said Dr. Alon Seri-Levy, Chief Executive Officer of Sol-Gel. “We thank the patients and investigators involved in the Twyneo trials. We look forward to submitting our NDA in the second half of 2020 and to working with the FDA through their review of our application, with a view to making Twyneo available to physicians and patients in the second half of 2021.”
If approved, Twyneo has the potential to be the first acne vulgaris treatment to bring together benzoyl peroxide and a potent retinoid, tretinoin, in a once-daily cream – enabled using the Company’s proprietary microencapsulation technology.
“Twyneo combines, for the first time, two of the safest and most effective topical agents available for the treatment of acne into a single application. Due to stability issues these products don’t play well together and we were never able to recommend even consecutive co-application of the two agents; Sol-Gel’s technology has solved that,” said Hilary Baldwin, M.D., Clinical Associate Professor of Dermatology, Rutgers Robert Wood Johnson School of Medicine, Medical Director, The Acne Treatment and Research Center, Past President the American Acne and Rosacea Society. “The data presented today show that this unique formulation offers superior efficacy without compromising tolerability in a very convenient treatment. I believe physicians will look forward to adding Twyneo to their acne treatments toolbox.”
SGT-65-04 and SGT-65-05 Trials Design To assess the efficacy and safety of Twyneo, 858 subjects, aged nine and older, with moderate-to-severe acne were enrolled in two multicenter, randomized, double-blind, parallel-group, vehicle-controlled trials (SGT-65-04 and SGT-65-05) at 63 sites across the U.S. Subjects were randomized at a 2:1 ratio to be treated once-daily with either Twyneo (n=571) or vehicle cream (n=287) for 12 weeks. The co-primary endpoints for both trials included: the proportion of patients who succeeded in achieving at least a two grade reduction from baseline and Clear (grade 0) or Almost Clear (grade 1) at Week 12 on a 5-point Investigator Global Assessment (IGA) scale; an absolute change from baseline in inflammatory lesion count at Week 12; and an absolute change from baseline in non-inflammatory lesion count at Week 12.
Co-Primary Endpoint Results (Intention-to-Treat Population)In trial SGT-65-04, 38.5% of patients treated with Twyneo achieved success in IGA versus 11.5% in the vehicle treated group (P
