Trial Outcomes & Findings for Evaluate Effectiveness of Epiduo® Gel in Reducing Antibiotic Sensitive & Resistant Strains of Propionibacterium (P)Acnes (NCT NCT00907101)

NCT ID: NCT00907101

Last Updated: 2022-08-01

Results Overview

Mean log10 values of P. acnes from swabbed skin samples Please note: Quantitative bacteriologic cultures were obtained from the facial skin (forehead) at screening, baseline, week 2 and week 4/early termination. Samples were obtained according to a modification of the technique of Williamson and Kligman. CFUs of P. acnes were counted at the dilution that contained between 10 and 100 CFUs. Total densities of P. acnes were calculated and reported as the average (of both plates) of the log10 CFUs per cm².

Timeframe: Week 4

Please note: Tolerability assessments were recorded separately from adverse events. Tolerability changes which may have required a temporary or permanent interruption of the subject's participation in the study (at his/her request or at the investigator's discretion), or concomitant treatment, was to be recorded in the AE form of the CRF. An entry was to be made on the AE form for all AEs.
