Brief Summary

Chlamydia is a common infection among youth and can be given from one person to another during sex. Many people who have chlamydia have no signs of infection at all, but can pass the infection to anyone they have sex with. If not treated, chlamydia can lead to serious health problems. This study will look at how well medicines given for chlamydia infection work. The study requires 306 evaluable subjects, chlamydia-positive, males and non-pregnant females, ages 12-21, living in long-term, gender-segregated youth correctional facilities. Participants will be assigned to receive either doxycycline (2 times per day, by mouth, for 7 days) or azithromycin (1 single dose by mouth). Study procedures will include collection of at least 3 urine samples to test for chlamydia. Study visits will occur during initial enrollment in the study, day 28 after starting treatment, and day 67. Participants will be involved in study related procedures for up to 67 days.

Outcome Measures

Primary Outcomes (1)

  • Assess Microbiological Failure of Recommended Azithromycin and Doxycycline Regimens in Uncomplicated Chlamydia Trachomatis Infection in a Setting Where Repeat Exposure to Chlamydia-infected Persons Can be Minimized.

    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).

    Study visit # 2 (Day 28 after therapy started)

Secondary Outcomes (1)

  • Demographical Characteristics and Clinical Parameters to Predict Treatment Outcome.
