NESS ZIONA, Israel, March 13, 2024 (GLOBE NEWSWIRE) -- Sol-Gel Technologies, Ltd. (NASDAQ:SLGL), a dermatology company with an innovative pipeline and approaches to develop a pioneering treatment for patients with severe skin conditions, is conducting a phase 3 clinical trial of SGT-610 (Patidegib gel, 2%), an Orphan Drug candidate with the potential to be the first therapy for preventing new basal cell carcinomas in Gorlin syndrome and partnered with Galderma to commercialize two approved large-category dermatology products, TWYNEO^® and EPSOLAY^®, in the U.S, today announced financial results for the full year ended December 31^st, 2023 and provided a corporate update.

2023 - Corporate Highlights and Recent Developments

• On November 30, 2023, Sol-Gel announced that it had begun Phase 3 testing of SGT-610 for Gorlin syndrome, with the first patient screened. Sol-Gel acquired Patidegib from PellePharm Inc. and is currently the only therapy in development to prevent the development of new BCC lesions in Gorlin syndrome patients. SGT-610 is a new topical hedgehog inhibitor to prevent the new basal cell carcinoma (BCC) lesions in patients with Gorlin syndrome that is expected to have an improved safety profile compared to oral hedgehog inhibitors. Sol-Gel is conducting a Phase-3 clinical trial to investigate SGT-610 in approximately 140 subjects at about 40 experienced clinical centers in North America, the United Kingdom, and Europe.
• On June 6, 2023, Sol-Gel and Searchlight Pharma Inc. announced licensing agreements to commercialize TWYNEO and EPSOLAY in Canada, according to which Sol-Gel is to receive up to $11 million in upfront payments and regulatory and sales milestones for both drugs, combined plus additional royalties ranging from low double digits to high- teen.
• On January 27, 2023, Sol-Gel announced the acquisition of topically applied patidegib, a hedgehog signaling pathway blocker, for the treatment of Gorlin syndrome for PellePharm Inc., for an upfront payment of $4.7 million, total development and NDA acceptance milestones of up to $6 million and based on the expected market potential up to $64 million in commercial milestones, as well as single digit royalties. Gorlin syndrome is a rare disease with no currently approved therapies by the U.S. Food and Drug Administration (FDA) or European Medical Association (EMA). Investigational compound SGT-610 has the potential to be the first-ever drug for the chronic prevention of BCCs in Gorlin syndrome patients if approved.
• Over the full year of 2023, TWYNEO grew its total prescriptions, with cumulative annual total prescriptions exceeding 106,000 and total prescriptions in the fourth quarter exceeding 27,000, as reported by IQVIA. The number of prescribers also grew quarterly, with a 6% growth of new prescribers for the fourth quarter. The majority of scripts were written by TWYNEO's high base of recurring prescribers, with fourth-quarter patient refills increasing by 12%, driven by a targeted adherence campaign. In addition, TWYNEO increased its broad commercial formulary coverage, with over 6 million additional lives covered between December 2022 and December 2023 per MMIT Analytics. (*)
• Over the full year of 2023, EPSOLAY also grew its total prescriptions every quarter, leading to cumulative annual total prescriptions of approximately 53,000 and total prescriptions in the fourth quarter exceeding 14,000, as reported by IQVIA. EPSOLAY also experienced quarterly growth in terms of the number of prescribers, with unique prescribers growing by 8% in the fourth quarter. Resulting from a targeted patient adherence campaign also for EPSOLAY, there was a significant increase in patient refills of 34% in the quarter. Overall, EPSOLAY grew commercial formulary coverage annually by over 12 million covered or better lives, according to MMIT Analytics.

Alon Seri-Levy, Ph.D., Chief Executive Officer of Sol-Gel, stated: "Sol-Gel is advancing the pivotal Phase 3 clinical trial with SGT-610 in accordance with the planned timelines and expects to have the results by the end of 2025. We estimate that the current trial protocol and its defined targets may facilitate the essential outcome, allowing Sol-Gel to provide Gorlin syndrome patients with the first drug that could prevent new BCCs, with a potential market estimated at more than $300 million. Concurrently, we are pursuing additional out-license agreements similar to the agreements signed this year with Searchlight Pharma for Canada. Sol-Gel's current product portfolio, led by SGT-610 and SGT-210, positions us with substantial assets for the future."

Financial Results for the Year Ended December 31^st, 2023

We generated $1.6 million in revenue in 2023, mainly related to the license agreements with Galderma and Searchlight, comprised of milestone and royalty payments, compared with $3.9 million in total revenues in 2022. The decrease in revenues in 2023 resulted mainly from the milestone payment from Galderma related to the FDA approval of Epsolay in 2022.

Our research and development expenses were $23.5 million for the year ended December 31, 2023, compared to $12.7 million for the year ended December 31, 2022. The increase of $10.9 million was primarily attributed to the $4.7 million upfront payment associated with the acquisition of topically applied patidegib, or SGT-610, $4.2 million related to the pivotal Phase 3 clinical trial for SGT-610, and $2.8 million related to clinical expenses for a generic product.

Our general and administrative expenses were $7.4 million for the year ended December 31, 2023, compared to $7.4 million for the year ended December 31, 2022.

Sol-Gel reported a net loss of $27.2 million and $1.01 or $1.01 per basic share and diluted share, compared to a net loss of $14.9 million in 2022 and a loss of $0.65 per basic and diluted share.

As of December 31, 2023, Sol-Gel had $17.6 million in cash, cash equivalent, and bank deposits and $20.4 million in marketable securities for a total balance of $38.0 in comparison to December 31, 2022, of $24.9 million in cash, cash equivalent, and bank deposit and $8.7 million in marketable securities for a total balance of $33.6 million. 

About Gorlin Syndrome and SGT-610

SGT-610, a hedgehog signaling pathway blocker, has the potential to be the first ever treatment for prevention of BCCs in Gorlin syndrome patients, if approved. Gorlin syndrome, an autosomal dominant genetic disorder affecting approximately 1 in 27,000-31,000 people in the U.S., is mostly caused by inheritance of one defective copy of the tumor suppressor patched homolog 1 (PTCH1) gene. Normally, the PTCH1 gene blocks the smoothened, frizzle class receptor (SMO) gene, turning off the hedgehog signaling pathway when it is not needed. Mutations in the PTCH1 gene may cause a loss of PTCH1 function, release of SMO, and may allow BCC tumor cells to divide uncontrollably. Patidegib, the active substance in SGT-610, is designed to block the SMO signal, thus, allowing cells to function normally and reducing the production of new tumors.
