Evaluation of new anti-infective drugs for the treatment of sexually transmitted chlamydial infections and related clinical syndromes. Infectious Diseases Society of America and the Food and Drug Administration.
This guideline addresses clinical trials of new antimicrobial agents in the treatment of uncomplicated genital infections caused by Chlamydia trachomatis and of syndromes resembling chlamydial infections. The most common clinical manifestations of chlamydial infection are urethritis in men and mucopurulent cervicitis in women. However, many chlamydial infections are not associated with inflammatory symptoms or signs. Culture is the diagnostic standard for defining the presence of C. trachomatis, although nonculture tests may be used in screening patients for enrollment in clinical trials. Susceptibility testing for C. trachomatis is laborious and difficult to standardize; only a few clinical isolates need to be tested in vitro. Prospective, randomized, double-blind, active-control comparative studies are recommended. Eradication of C. trachomatis defines both microbiological success and overall cure for chlamydial infection, but clinical and nonmicrobiological laboratory criteria are paramount in assessing the therapeutic response in nonchlamydial urethritis or cervicitis.
