FDA Approves Twyneo
FDA Approves Twyneo (tretinoin and benzoyl peroxide) for the Treatment of Acne Vulgaris
NESS ZIONA, Israel, July 27, 2021 (GLOBE NEWSWIRE) — Sol-Gel Technologies, Ltd. (NASDAQ: SLGL), a dermatology company focused on identifying, developing and commercializing branded and generic topical drug products for the treatment of skin diseases, today announced that the Food and Drug Administration (FDA) has approved its first proprietary drug product, Twyneo (tretinoin/benzoyl peroxide) cream, 0.1%/3%, indicated for the treatment of acne vulgaris in adults and pediatric patients nine years of age and older. Twyneo uses Sol-Gel’s patented technology to entrap tretinoin, a retinoid, and benzoyl peroxide within silica-based microcapsules to stabilize tretinoin from being degraded by benzoyl peroxide and to slowly release each of the active drug ingredients over time to provide a favorable efficacy and safety profile. Twyneo is patent protected until 2038. Sol-Gel has partnered with Galderma to commercialize Twyneo in the U.S. Sol-Gel expects to receive a regulatory milestone payment in conjunction with this approval and retains the option to regain U.S. commercialization rights five years following first commercialization in the U.S.
“The FDA approval of Twyneo underscores our ability to deliver innovative, proprietary drugs to the market,” stated Dr. Alon Seri-Levy, Co-Founder and Chief Executive Officer of Sol-Gel. “Based on the clinical data observed, we believe that Twyneo has the potential to change the treatment landscape for the tens of millions of patients suffering from acne vulgaris. With market leader, Galderma, handling the product launch of Twyneo, we are excited that Twyneo will soon be available to patients in the U.S.,” continued Dr. Seri-Levy. “We remain focused on obtaining FDA approval of Epsolay® (benzoyl peroxide), our other Galderma-partnered product – the approval of which has been delayed due to FDA’s COVID-19-related restrictions. We are also making progress on our innovative earlier stage programs for erlotinib, roflumilast and tapinarof with the intent of advancing them into the clinic,” he concluded.
“Galderma was founded forty years ago around a commitment to serve the dermatological needs of healthcare professionals and their patients,” said Baldo Scassellati Sforzolini, Global Head of Research & Development at Galderma. “Our heritage in acne dates back to our founding and we are excited to partner with Sol-Gel to bring yet another acne innovation to market for a condition that impacts up to 50 million Americans annually.1”
“Twyneo combines, for the first time, two of the most commonly used topical agents available for the treatment of acne into a single application. Due to stability issues, these products don’t play well together, and we were never able to recommend even consecutive co-application of the two agents. Sol-Gel’s technology has solved this problem,” said Hilary Baldwin, M.D., Clinical Associate Professor of Dermatology, Rutgers Robert Wood Johnson School of Medicine, Medical Director, The Acne Treatment and Research Center and Past President of the American Acne and Rosacea Society. “The approval of Twyneo offers patients efficacy with these two products in a single convenient application. I believe physicians will look forward to adding Twyneo to their acne treatments toolbox.”
The New Drug Application (NDA) for Twyneo was approved by the FDA on July 26, 2021. The NDA was supported by positive results from two Phase 3, randomized, double-blind, vehicle-controlled, multi-center studies (NCT03761784, and NCT03761810), in which Twyneo demonstrated efficacy and a favorable tolerability profile in subjects nine years of age and older with facial acne vulgaris. Twyneo is the first FDA-approved fixed-dose combination of tretinoin and benzoyl peroxide. For more information, visit www.sol-gel.com.
About Acne Vulgaris
Acne vulgaris is a common multifactorial skin disease that according to the American Academy of Dermatology affects up to 50 million people in the U.S. The disease occurs most frequently during childhood and adolescence (affecting 80% to 85% of all adolescents) but it may also appear in adults. Acne vulgaris 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 vulgaris 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.
Twyneo is a topical cream containing a fixed‑dose combination of tretinoin, 0.1%, and benzoyl peroxide, 3%, for the treatment of acne vulgaris in adults and pediatric patients nine years of age and older. Twyneo is the first acne treatment that contains a fixed‑dose combination of benzoyl peroxide and tretinoin. Tretinoin and benzoyl peroxide are widely prescribed separately for acne vulgaris; 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 formulation of Twyneo uses silica (silicon dioxide) core shell structures to separately micro-encapsulate tretinoin crystals and benzoyl peroxide crystals enabling inclusion of the two active ingredients in the cream.
Indications and Usage
Twyneo is a combination of tretinoin, a retinoid, and benzoyl peroxide indicated for the topical treatment of acne vulgaris in adults and pediatric patients 9 years of age and older.
IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS: History of serious hypersensitivity reaction to benzoyl peroxide or any component of Twyneo.
WARNINGS AND PRECAUTIONS
- Hypersensitivity: Severe hypersensitivity reactions, including anaphylaxis and angioedema, have been reported with use of benzoyl peroxide products.
- Skin Irritation: Pain, dryness, exfoliation, erythema, and irritation may occur with use of Twyneo. Avoid application of Twyneo to cuts, abrasions, eczematous or sunburned skin.
- Photosensitivity: Minimize unprotected exposure to sunlight and sunlamps. Use sunscreen and protective clothing when sun exposure cannot be avoided.
ADVERSE REACTIONS: The most common adverse reactions (incidence ≥ 1%) are pain, dryness, exfoliation, erythema, dermatitis, pruritus and irritation (all at the application site).
Epsolay is an investigational topical cream containing benzoyl peroxide, 5%, for the treatment of inflammatory lesions of rosacea, also known as papulopustular rosacea, in adults. If approved, Epsolay has the potential to be the first FDA-approved single-active benzoyl peroxide prescription drug product. The benzoyl peroxide in Epsolay is in a solid form that is incorporated into silica-based microcapsules. Epsolay is not approved by the FDA and the safety and efficacy have not been established.
