Clinical Study for Topical Lupeol in Acne

Study Overview
=================
Brief Summary
-----------------
Double-blind, randomized,4-week small-scale clinical trial for lupeol in the treatment of inflammatory and non-inflammatory acne lesions in split face fashion

Detailed Description
-----------------
To investigate the clinical efficacy and tolerability of lupeol for the treatment of facial acne, we conducted a small-scale, randomized, double-blinded, split-face clinical trial over the course of 4 weeks. Fifteen of 16 enrolled patients completed the study, in which affected areas on half each patient's face were treated with 2% lupeol twice daily while the other side of the face was treated with a vehicle control. Clinical visits were scheduled at baseline and at 2 and 4 weeks. The primary outcome of the study was the percent change in inflammatory lesions (papules, pustules, and nodules) at 4 weeks. The secondary outcomes were the percent change in non-inflammatory lesions (open and closed comedones) and the change in the Leeds revised acne grading system score at 4 weeks. Adverse events (AEs) were defined as all unintended and harmful signs or symptoms; these were assessed by both patients' self-reporting and physicians' skin examination at each visit. Results were analyzed using intent to treat (ITT) groups. The per-protocol (PP) population consisted of the 15 patients who did not have any major protocol deviations. Last observation carried forward (LOCF) analysis was used to evaluate the primary and secondary outcomes. ** Randomization and blindness process ** At the time of initial presentation, an evaluation of acne severity was performed using both individual counts of inflammatory and non-inflammatory acne lesions and an assessment of the Leeds revised acne grading system score. Then, patients were randomly assigned to either left- or right-sided lupeol application, with the other side of the face assigned to vehicle-control application. A simple random allocation sequence was created using computer-based random number generators with a block size of 4. All dermatologists participating in outcome assessments, a physician assistant managing trial enrollment and administration, medical statisticians analyzing the data, and patients were blinded to the assignments. Randomization codes were strictly secured in a safe in the administration office of the clinical research center until data entry was complete. The integrity of the blinding was ensured by packaging the study- and control products in identical tubes and by requiring a third party (other than the investigator/evaluator) to dispense the medication. In addition, both topical agents were identical in color and odor.
