Trial Outcomes & Findings for Treatment Failure of Chlamydial Infection in Males and Females in Youth Correctional Facilities (NCT NCT00980148)
NCT ID: NCT00980148
Last Updated: 2015-03-18
Results Overview
The proportion of participants with testing by Gen-Probe Aptima Combo 2 that is positive for C. trachomatis and C. trachomatis OmpA (Major Outer Membrane Protein) genotyping reveals the baseline chlamydial strain and the repeat positive chlamydial strain to be the same genotype (i.e., concordant).

PRIMARY outcome
Timeframe: Study visit # 2 (Day 28 after therapy started)Population: The per protocol population is comprised of participants who completed therapy and whose failure status could be established at the day 28 visit. Participants were considered to have completed therapy if they took a single dose of azithromycin or at least 10 of the 14 doses of doxycycline.
The proportion of participants with testing by Gen-Probe Aptima Combo 2 that is positive for C. trachomatis and C. trachomatis OmpA (Major Outer Membrane Protein) genotyping reveals the baseline chlamydial strain and the repeat positive chlamydial strain to be the same genotype (i.e., concordant).

6/155 • Number of events 7 • Adverse events (AEs) that occur after study drug administration (Study Visit 1) and through the first follow-up visit (Study Visit 2, Day 28) were recorded. AEs were followed until resolution even if this extended beyond the study-reporting period.
Resolution of an AE is defined as the return to pretreatment status or stabilization of the condition with the expectation that it will remain chronic. In Sept 2010, the protocol was amended to streamline reportable AE's by limiting to GI related symptoms, vaginal irritation or itching, and dermatologic reactions.
