NESS ZIONA, Israel, March 10, 2023 (GLOBE NEWSWIRE) — Sol-Gel Technologies, Ltd. (NASDAQ: SLGL), a dermatology company with two innovative dermatology products that were launched in the U.S. and an innovative pipeline, today announced financial results for the full year ended December 31, 2022 and provided a corporate update.

2022 Corporate Highlights and Recent Developments

• On January 27, 2023, Sol-Gel announced the acquisition of topically applied patidegib, a hedgehog signaling pathway blocker, for the treatment of Gorlin syndrome from PellePharm, Inc. for an upfront payment of $4.7 million, total development and NDA acceptance milestones of up to $6.0 million, and based on the expected market potential up to $64.0 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 treatment of Gorlin syndrome, if approved. The Company is suspending the development of SGT-310 and SGT-510 in psoriasis to allow for accelerated development of SGT-610 targeted for an underserved indication.
• Related to the acquisition, Sol-Gel announced the pricing of $22.8 million in parallel registered direct and private placement offerings, the proceeds from which will be used to support the Phase 3 trial of patidegib beginning in late 2023 and for general corporate purposes. Shareholder approval of the $10 million private placement is still pending and is expected by end of March.
• Prescribers reported positive experiences with TWYNEO (launched in April 2022), with the recurring base of prescribers increasing to a high of 82% in Q4 2022, from 66% in Q3 2022. The recurring base of prescribers, defined as the percentage of all TWYNEO prescribers who have written since launch and continue to prescribe, is a positive indicator of the drug’s acceptance. According to IQVIA data, there have been over 106,000 prescriptions written for TWYNEO in 2022.
• Only 6 months post its June 2022 launch, EPSOLAY captured the #2 branded topical position in rosacea in Q4 2022. EPSOLAY’s recurring base of prescribers increased to 64% of its total prescribers in Q4 2022, from 22% in Q3 2022, showcasing sizeable post-trial adoption. According to IQVIA data, there have been over 26,000 prescriptions of EPSOLAY written in 2022,
• In the first year of market availability, TWYNEO cream has achieved broad managed care adoption and coverage of 60% of commercial covered lives across the three major Pharmacy Benefit Managers (PBMs). Additionally, commercial payer coverage for EPSOLAY is now at over 40% of commercial covered lives.
• Throughout the year, Galderma has had a presence promoting TWYNEO and EPSOLAY at major dermatology meetings and supporting peer-to-peer engagement. At the American Academy of Dermatology taking place on March 17-21, 2023 in New Orleans, Louisiana, Galderma plans to host several medical education events and to support brand visibility of both TWYNEO and EPSOLAY with dedicated expert presentations.

Alon Seri-Levy, Ph.D., Chief Executive Officer of Sol-Gel, stated, “With the recent acquisition of patidegib, a Breakthrough-designated Orphan Drug candidate with a market potential of over $300 million, Sol-Gel has successfully pivoted towards the attractive rare disease segment and the major unmet need for Gorlin syndrome patients. We are also extremely encouraged by the rapid market uptake of our Galderma-partnered products, TWYNEO and EPSOLAY, by prescribers, patients, and payors during their first year on the market and remain confident about prospects to improve TWYNEO and EPSOLAY reimbursement and profitability over time. We will seek to out-license non-U.S. rights for TWYNEO and EPSOLAY and generate non-dilutive income.”

Financial Results for the Year Ended December 31, 2022

Total revenue was $3.9 million, which consisted of $3.9 million of licensing revenue compared to revenues of $31.3 million in 2021 which consisted of $7.5 million of licensing revenue and $23.8 million of collaboration revenue.

Research and development expenses were $12.7 million compared to $20.4 million in 2021. The decrease of $7.7 million was mainly attributed to a decrease in professional expenses related to EPSOLAY and TWYNEO.

General and administrative expenses were $7.4 million in 2022 compared to $8.5 million in 2021. The decrease of $1.1 million was mainly attributed to a decrease in commercialization expenses related to EPSOLAY and TWYNEO.

Sol-Gel reported net loss of $14.9 million in 2022 and loss of $0.65 per basic and diluted share, compared to net income of $3.2 million and earnings of $0.14 per basic and diluted share in 2021.

As of December 31, 2022, Sol-Gel had $24.9million in cash, cash equivalents and bank deposits, and $8.7 million in marketable securities for a total balance of $33.6million. Following the $22.8 million raised in the recent financing, the Company expects that its cash resources will enable funding of operational and capital expenditure requirements into the second half of 2025.

About Gorlin Syndrome and SGT-610

SGT-610, a hedgehog signaling pathway blocker, has the potential to be the first ever treatment for Gorlin syndrome, 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 basal cell carcinoma (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.
