• Epsolay^®and Twyneo^®PDUFA goal dates set for April 26, 2021 and August 1, 2021 respectively

• Top-line generic product revenue of $8.7 million in fiscal 2020

• Signed additional generic product collaboration agreements with Perrigo, bringing the number of collaborations between the companies to 12

NESS ZIONA, Israel, March 04, 2021 (GLOBE NEWSWIRE) -- Sol-Gel Technologies, Ltd. SLGL, a clinical-stage dermatology company focused on identifying, developing and commercializing branded and generic topical drug products for the treatment of skin diseases, today announced financial results for the full year ended December 31, 2020 and provided corporate updates.

"I am very pleased with the major milestones that were achieved by Sol-Gel last year. After announcing positive data from Phase 3 trials of Epsolay and Twyneo and submitting NDAs to the FDA within guided timelines, 2020 was highlighted by positive acceptances of both NDAs and allocated PDUFA dates," commented Dr. Alon Seri-Levy, Chief Executive Officer of Sol-Gel.

"Given the competitive landscape of the dermatology market and the significant capital that would be needed to directly commercialize our products, our current operational model assumes we will partner with a dermatology company that has a strong market presence. This would enable us to capture market share more quickly without the need to invest in building our own marketing and sales force and would allow us to further invest in the development of our pipeline of products with larger potential markets," continued Dr. Seri-Levy.

Corporate Highlights and Recent Developments

Sol-Gel announced the U.S. Food and Drug Administration's (FDA) acceptance of New Drug Application (NDA) for Epsolay (benzoyl peroxide, 5%, cream) with a Prescription Drug User Fee Act (PDUFA) goal date set for April 26, 2021. If approved, Epsolay has the potential to be the first FDA-approved, single-agent benzoyl peroxide prescription drug product for the treatment of inflammatory lesions of rosacea.
Sol-Gel announced FDA acceptance of NDA for Twyneo (benzoyl peroxide, 3%, and tretinoin, 0.1%, cream) with a PDUFA goal date set for August 1, 2021. If approved, Twyneo has the potential to be the first FDA-approved acne treatment that contains fixed-dose combination of benzoyl peroxide and tretinoin.
Sol-Gel is in discussions with potential partners regarding the commercialization of Epsolay and Twyneo in the United States to occur if the product candidates receive regulatory approval from the FDA.
In preparation for commercial launch of proprietary products the Company has opened a US headquarters in Whippany, NJ.
Sol-Gel was informed by its collaboration partner that the launch of an FDA-approved generic drug is expected in the second quarter of 2021. Annual sales of the brand name product exceeded $180 million in the United States in 2019.
In 2020, Sol-Gel signed four additional collaboration agreements with Perrigo for the development, manufacture, and commercialization of new generic product candidates, bringing the total number of collaborations between the companies to 12.
Pre-clinical testing of erlotinib (an epidermal growth factor receptor inhibitor), tapinarof (an investigational aryl hydrocarbon receptor modulator), and roflumilast (an investigational phosphodiesterase 4 inhibitor) is progressing for various new pharmaceutical indications. A total of 25 provisional patent applications for these project candidates have been submitted to date.
The enrollment of patients in the Phase 1 proof-of-concept study with SGT-210 (erlotinib gel) in patients with palmoplantar keratoderma has been slowed by the COVID-19 pandemic. The Company expects to report top-line data in the third quarter of 2021.
In 2020, the Company completed financings totaling $28.0 million in gross proceeds, including the proceeds of the February underwritten public offering of $23.0 million and from the $5.0 million invested in April by Sol-Gel's controlling shareholder, M. Arkin Dermatology Ltd.

Financial Results for the Year Ended December 31, 2020

Revenue in 2020 was $8.8 million. The revenue was mainly due to sales of a generic product from a collaboration arrangement with Perrigo.

Research and development expenses were $27.9 million in 2020 compared to $40.6 million during the same period in 2019. The decrease of $12.7 million was mainly attributed to a decrease of $17.9 million in clinical trial expenses, mainly due to the completion of the clinical trials of Epsolay and Twyneo towards the end of 2019, a decrease of $0.4 million in other expenses, mainly due to the purchase of raw material for manufacturing, partially offset by an increase of $5.4 million in manufacturing expenses.

General and administrative expenses were $11.1 million in 2020 compared to $8.3 million in 2019. The increase of $2.8 million was mainly attributed to an increase of $3.0 million in commercialization expenses and an increase of $0.4 million in patent related expenses, partially offset by a decrease of $0.7 million in stock based compensation expenses.

Sol-Gel reported a loss of $29.3 million for the full year of 2020 compared to loss of $24.6 million for the same period in 2019.

As of December 31, 2020, Sol-Gel had $28.5 million in cash, cash equivalents and deposits, and $21.7 million in marketable securities for a total balance of $50.2 million. Sol-Gel expects its existing cash resources will enable funding of operational and capital expenditure requirements into the third quarter of 2022.

About Epsolay^®

Epsolay is an investigational topical cream containing encapsulated benzoyl peroxide, 5%, for the treatment of papulopustular rosacea. Epsolay utilizes a patented technology process to encapsulate benzoyl peroxide within silica-based microcapsules to create a barrier between the medication and the skin. The slow migration of medication from the microcapsules is designed to deliver an effective dose of benzoyl peroxide onto the skin, while reducing the ability of benzoyl peroxide to induce skin irritation, such as erythema, burning and stinging. If approved, Epsolay has the potential to be the first FDA-approved single-active benzoyl peroxide prescription drug product. Epsolay is not approved by the FDA and the safety and efficacy has not been established.

About Papulopustular Rosacea

Papulopustular 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.

About Twyneo^®

Twyneo is an investigational, fixed-dose combination of encapsulated benzoyl peroxide, 3%, and encapsulated tretinoin, 0.1%, cream for the treatment of acne vulgaris. If approved, it will be the first acne treatment that contains a fixed-dose combination of benzoyl peroxide and tretinoin, which are separately encapsulated in silica using Sol-Gel's proprietary microencapsulation technology. Tretinoin and benzoyl peroxide are widely prescribed separately as a combination treatment for acne; however, benzoyl peroxide causes degradation of the tretinoin molecule, thereby potentially reducing its effectiveness if used at the same time or combined in the same formulation. The silica-based microcapsule is designed to protect tretinoin from oxidative decomposition by benzoyl peroxide, thereby enhancing the stability of the active drug ingredients. The silica-based shell is also designed to release the ingredients slowly over time to provide a favorable efficacy and safety profile. Twyneo is not approved by the FDA and the safety and efficacy has not been established.

About Acne Vulgaris

Acne vulgaris is a common multifactorial skin disease that according to the American Academy of Dermatology affects approximately 40 to 50 million people in the United States. The disease occurs most frequently during childhood and adolescence (affecting 80% to 85% of all adolescents) but it may also appear in adults. Acne patients suffer from the appearance of lesions on areas of the body with a large concentration of oil glands, such as the face, chest, neck and back. These lesions can be inflamed (papules, pustules, nodules) or non-inflamed (comedones). Acne can have a profound effect on the quality of life of those suffering from the disease. In addition to carrying a substantial risk of permanent facial scarring, the appearance of lesions may cause psychological strain, social withdrawal and lowered self-esteem.
