A Study of the Clinical Efficacy and Safety of 20% Cassia Alata Extract Against Tinea Versicolor

Overview

The goal of this clinical trial is to establish the efficacy of Cassia alata extract as a cream form in treating tinea versicolor (liver spots/shifting clouds). The main questions the study aims to answer are:• Does the use of this extract help resolve tinea versicolor better than no treatment? Does the use of this cream have significant side effects i.e, is it safe? Participants will be asked to treat a designated area while leaving additional areas untreated. 1-2 finger tip units of cream will be applied to the treatment site twice daily at least 8 hours apart. Participants will attend the trial clinic every 4 weeks for 12 weeks.

Tinea (pityriasis) versicolor is a common superficial fungal infection. A variety of topical antifungals are used in its treatment. In Jamaica, many people use crushed leaves of the Cassia alata plant (Senna alata) as a traditional remedy. Rare investigators have described its activity against the causative fungus, Malassezia spp. Aim: We wish to confirm the efficacy of the extract, devise dosing regimen, document potential side effects Study Design/Methodology: A single-arm arm no-treatment self-controlled trial pilot study evaluating the clinical efficacy and safety profile of 20% Cassia alata cream against tinea versicolor. Therapeutic efficacy reported as clinical and microbiological resolution of tinea versicolor in treated area will be assessed and compared with non-treated areas. Side effects and ease of use will be evaluated for and reported. Assessment will occur at baseline, 1 week, 4 weeks, 8 weeks and 12 weeks. Demographics will be tabulated and categorical variables generated. Associations of the presence/absence of these variables within both groups will be evaluated for using chi-squared tests. Results will be analyzed using SPSS version 26. Location: Dermatology Division (Room 13 Dept of Pathology) at University Hospital of the West Indies. Data Storage: Unique study ID, locked room and password protected computer belonging to the principal investigator. Only approved study investigators will have access. Time frame: 24 months months Confidentiality Statement: This study requires approval by the Ethics Committee, will require an informed consent and will comply with ethical rules governing research using human subjects, patient confidentiality and non-coercion as detailed within the proposal.
