    On July 27, 2021, Sol-Gel Technologies announced that the US FDA has approved its innovative combination therapy Twyneo cream for the treatment of acne vulgaris (acne vulgaris) in adults and children aged 9 years and older
    Twyneo is a fixed-dose compound topical cream containing 0.
    1% tretinoin and 3% benzoyl peroxide.
    Clinical trials have proved that it has significant efficacy and good safety characteristics

    The press release pointed out that this is also the first fixed-dose combination of these two drugs approved by the FDA


    Acne vulgaris is a common multifactorial skin disease that most commonly occurs in children and adolescents, affecting 80%-85% of adolescents, but it may also occur in adults
    Skin lesions appear in areas where a large number of oil glands in the patient’s body, such as the face, chest, neck, and back, are inflammatory (papules, pustules, nodules) or non-inflammatory (acne) lesions

    Acne can have a profound impact on the quality of life of patients

    In addition to the major risk of permanent facial scars, it may also cause psychological stress, social fear, and decreased self-esteem


    Tretinoin and benzoyl peroxide are widely used in the treatment of acne vulgaris, respectively.
    If the effects of the two drugs can be used at the same time, the curative effect on patients will be stronger

    However, because benzoyl peroxide can cause the degradation of tretinoin molecules, its combination therapy may reduce the efficacy of tretinoin

    In order to solve this problem, Twyneo uses Sol-Gel's microencapsulation technology to encapsulate tretinoin and benzoyl peroxide in silica microcapsules.
    This structure can stabilize tretinoin and benzoyl peroxide.
    It is degraded by benzoyl peroxide and can slowly release the respective active pharmaceutical ingredients over time, resulting in good efficacy and safety characteristics

    The approval is based on the positive results of two randomized, double-blind, excipient-controlled, multi-center Phase 3 clinical trials
    Test data show that Twyneo has significant efficacy and well tolerated characteristics in patients with facial acne vulgaris 9 years and older
