NESS ZIONA, Israel, May 12, 2023 (GLOBE NEWSWIRE) -- Sol-Gel Technologies, Ltd. (NASDAQ: SLGL), a dermatology company with two innovative dermatology products, EPSOLAY and TWYNEO, that were launched in the U.S., SGT-610, which is Phase 3-ready, and an earlier-stage SGT-210, today announced financial results for the first quarter ended March 31, 2023 and provided a corporate update.

“This year we turned our focus towards a high-value segment of dermatology and helping those patients with significant unmet needs. We remain on track with our plans to initiate the pivotal Phase 3 trial for SGT-610, or patidegib, our recently acquired, Breakthrough-designated, Orphan Drug candidate with a market potential of over $300 million for the treatment of Gorlin syndrome, in late 2023,” stated Alon Seri-Levy, Ph.D., Chief Executive Officer of Sol-Gel. “In parallel, we continue to be pleased by the pace of uptake by prescribers, patients and payors for our Galderma-partnered products, TWYNEO and EPSOLAY. Galderma had an impressive presence to support both brands at the American Academy of Dermatology in March of this year, hosting several educational events and thought-leader presentations for physicians, and then held a targeted sales force training on EPSOLAY ahead of peak rosacea season. We remain confident about prospects to improve TWYNEO and EPSOLAY reimbursement and profitability over time and continue to seek out-licensing opportunities for our non-U.S. rights to both drugs.”

Q1 2023 and Recent Corporate 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; in addition, Sol-Gel agreed to pay PellePharm 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.

• 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 support the Phase 3 trial of patidegib expected to begin in the fourth quarter of 2023 and for general corporate purposes. The $10 million private placement portion of the offering was approved by shareholders on March 30, 2023 and received in April 2023.

• Prescribers continue to report positive experiences with TWYNEO (launched in April 2022), with the recurring base of prescribers increasing to a high of 98% in the first quarter of 2023, from 82% in the fourth quarter of 2022, with consistent prescribing quantities per healthcare provider and increasing patient refill rates. The recurring base of prescribers, defined as the percentage of all TWYNEO prescribers who have written since launch and continue to prescribe, continues to be a positive indicator of the drug’s acceptance. According to IQVIA data, there have been over 28,000 prescriptions written for TWYNEO in the first quarter of 2023.

• As of Q1 2023, nine months post its June 2022 launch, EPSOLAY remains at the #2 position among branded topical rosacea treatments. EPSOLAY’s recurring base of prescribers increased to 92% of its total prescribers in Q1 2023, from 64% in the fourth quarter of 2022, and prescriptions written per provider continue to increase along with patient refill rates. According to IQVIA data, there have been over 12,000 prescriptions of EPSOLAY written in the first quarter of 2023.

• Since launching, TWYNEO and EPSOLAY have improved their commercial managed care accessibility, reaching over 60% and 40% of commercial covered lives respectively. Beyond broad managed care adoption of TWYNEO across the three major Pharmacy Benefit Managers (PBMs), the drug was moved by CVS Corporation to preferred status on its formulary as of January 1, 2023; while EPSOLAY is now also covered by Express Scripts Holding Company and OptumRx, Inc.

• Galderma hosted several medical education events to support brand visibility of both TWYNEO and EPSOLAY at the American Academy of Dermatology in March and also held targeted sales force education and training activities for EPSOLAY ahead of Rosacea Awareness Month in April, during peak rosacea season, to drive increased prescription volumes.

• Sol-Gel has completed a Phase 1 study of SGT-210, or erlotinib, an EGFR inhibitor. The trial was designed as a single-center, single-blind, parallel-group, maximal use systemic exposure (MUSE) study evaluating the pharmacokinetics, safety and tolerability of erlotinib topical treatment in healthy volunteers. A total of 12 healthy adult subjects were assigned to two doses of erlotinib treatment in a 1:1 ratio. The subjects were treated once daily for 28 days. Study results showed the topical therapy had no systemic absorption-related adverse events affecting patient treatment adherence and minimal systemic absorption was detected. Study drug-related adverse events were mainly designated as mild, and all were resolved during study duration. Results from this Phase 1 study support further development of this product candidate.
  

Financial Results for the Quarter Ended March 31, 2023

Total revenue in the first quarter was $0.8 million, which primarilyconsisted of licensing revenue compared to nominal revenues for the same period in 2022.

Research and development expenses were $9.4 million compared to $4.0 million for the same period in 2022. The increase of $5.4 million was primarily attributed to the $4.7 million upfront payment associated with the acquisition of topically applied patidegib.

General and administrative expenses were $2.0 million in 2023 compared to $1.9 million for the same period in 2022. The increase of $0.1 million was mainly attributed to an increase in professional expenses.

Sol-Gel reported net loss of $10.3 million for the first quarter of 2023 and a loss of $0.41 per basic and diluted share, compared to a net loss of $5.6 million and a loss of $0.24 per basic and diluted share for the same period in 2022.

As of March 31, 2023, Sol-Gel had $20.3 million in cash, cash equivalents and deposits, and $18.4 million in marketable securities for a total balance of $38.7 million. The balance as of March 31, 2023, does not include $10 million received in April 2023 as part of 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.
