Introduction: Current topical treatments for psoriasis offer limited efficacy and are associated with long-term adverse effects in a subset of patients, highlighting the need for new therapeutic options. Cannabidiol (CBD), a non-psychoactive cannabinoid derived from Cannabis sativa L., has shown potential in reversing psoriasis pathology through its action on skin receptors in preclinical studies. Given the promising properties of CBD, transdermal patches containing this compound represent a novel approach to psoriasis treatment. However, comprehensive data on their efficacy and safety remain scarce. Methods: We outline a randomized, double-blind, placebo-controlled trial to assess the efficacy and safety of CBD transdermal patches with minimal tetrahydrocannabinol (THC) in 60 patients with mild to moderate plaque-type psoriasis at a university hospital in Thailand (n=60). This study aims to evaluate the changes in the Local Psoriasis Severity Index (LPSI), itch score via a visual analog scale, and occurrence of adverse events on day 0, 30, 60, and 90 of the study. Additionally, we will examine the alteration in the skin, gut, and oral microbiome in a subset of participants to explore potential correlations with treatment outcomes. The primary outcome will focus on the difference in LPSI scores at the end of the study period, employing an intention-to-treat analysis. Multivariate logistic regression will be used to identify baseline clinical and microbiological predictors of ...
