Sol-Gel Technologies and Galderma Announce Exclusive Licenses for the Commercialization of EPSOLAY® and TWYNEO® in the United States

- Upfront and approval payments of up to $15 million

- Tiered royalties ranging from mid- to high-teen percentage of net sales

- Sol-Gel option to regain commercialization rights 5 years following first commercialization

Sol-Gel Technologies, Ltd. (NASDAQ: SLGL), a clinical-stage dermatology company, and Galderma, the world’s largest independent dermatology company, today announced they have signed two exclusive 5-year license agreements for the commercialization of EPSOLAY® and TWYNEO® in the United States.

Under these agreements, Galderma has an exclusive license to commercialize Sol-Gel’s most advanced investigational drug products using Sol-Gel’s proprietary micro-encapsulation technology, in each case provided the product is approved by the FDA:

• EPSOLAY (benzoyl peroxide, 5%, cream) is under investigation for the treatment of inflammatory lesions of rosacea in adults, with a Prescription Drug User Fee Act (PDUFA) goal date originally set for April 26, 2021. Action on the NDA for EPSOLAY has not yet been taken due to the inability of the FDA to conduct a pre-approval inspection of the production site of EPSOLAY due to COVID-19 travel restrictions.
• TWYNEO (benzoyl peroxide, 3%, and tretinoin, 0.1%, cream) is under investigation for the treatment of acne vulgaris with a PDUFA goal date set for August 1, 2021.

Sol-Gel is entitled to up to $15 million in upfront payments and regulatory approval milestone payments assuming 2021 approval of both products. Sol-Gel is also eligible to receive tiered double-digit royalties ranging from mid-teen to high-teen percentage of net sales as well as up to $9 million in sales milestone payments.

“Galderma already owns the current market leading brands for rosacea and acne, and I am therefore delighted that Galderma views EPSOLAY and TWYNEO as innovative and with the potential to become key market brands,” stated Dr. Alon Seri-Levy, Chief Executive Officer of Sol-Gel. “Our partnerships with Galderma represent an important development for rosacea and acne patients while also strengthening our balance sheet by providing non-dilutive capital without compromising our desire to establish Sol-Gel as a leading dermatology company. We intend to remain focused on developing our promising pipeline and we are appreciative of the flexibility that these agreements provide through Sol-Gel retaining commercial rights after the initial five-year term,” commented Dr. Seri-Levy.

“Innovation is at the heart of our commitment to advancing dermatology,” said Baldo Scassellati Sforzolini, Global Head of Research & Development at Galderma. “The potential to deliver two innovative products featuring Sol-Gel’s proprietary micro-encapsulation technology represents an important milestone for acne and rosacea patients and underscores Galderma’s position as the partner of choice in dermatology.”

About EPSOLAY

EPSOLAY is an investigational topical cream containing encapsulated benzoyl peroxide, 5%, for the treatment of inflammatory lesions of rosacea, also known as papulopustular rosacea, in adults. 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 silica-based shell is designed to release benzoyl peroxide slowly over time to provide a favorable efficacy and safety profile. 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 have not been established.

About Papulopustular Rosacea

Papulopustular rosacea is a chronic and recurrent inflammatory skin disorder that affects nearly 5 million Americans. Rosacea 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 inflammatory lesions (papules and pustules) 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, TWYNEO 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 micro-encapsulation 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 have 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.
