Summary
BTX 1503 contains the active pharmaceutical ingredient, cannabidiol in a topical liquid formulation, and is being developed for the treatment of acne vulgaris by Botanix Pharmaceuticals Limited. CBD is a member of a broader family of compounds known as cannabinoids, a class of compounds originally derived from the cannabis sativa plant. CBD is chemically synthesized under Good Manufacture Practices (GMP) for use in this study. The objective of this study is to assess safety and efficacy of various doses of BTX 1503 in subjects with moderate to severe acne vulgaris of the face. This will be a multi-center, randomized, double-blinded, vehicle-controlled, parallel group, dose-finding study in pediatrics, adolescents and adults (aged 12 to 40 years). Study participants will be enrolled at sites in Australia and United States of America. Not all sites will enrol paediatric participants. Participants will be randomised to one of five treatment arms: BTX 1503 5%, BID:BTX 1503 5%, QD:BTX 1503, 2.5% QD:Vehicle, BID:Vehicle QD) with 90 subjects in each BTX 1503 group and 45 subjects in each vehicle group for a total of 360 subjects. Participants will be provided with instructions for dose administration and will be asked to self-administer for 28 consecutive days. Safety and cutaneous tolerability will be assessed by the collection and review of AEs and application site review, laboratory parameters throughout the duration of the trial. Efficacy measurements will include change in inflammatory and non-inflammatory lesion counts from baseline. Photography of the face will be conducted for some participants.. Participants will remain in follow up until 84 days following the first application of investigational product, with outpatient visits at Days 1, 14, 28, 56 and 84.
