This study has been completed.
Information provided by (Responsible Party):
Warner Chilcott Identifier:
First received: April 28, 2010
Last updated: December 21, 2011
Last verified: December 2011
Evaluate the clinical efficacy and safety of WC2031 200 mg tablets taken orally once a day for 7 days versus Vibramycin (doxycycline) 100 mg capsules taken orally twice a day for 7 days, for the treatment of uncomplicated urogenital Chlamydia trachomatis infection. Primary efficacy endpoint is microbiological cure at Day 28. Safety assessments are adverse events, changes in vital signs and laboratory test results.

Condition Intervention Phase
Urogential Chlamydia Trachomatis Infection
Drug: Doxycyline Hyclate tablet
Drug: Vibramycin (doxycyline hyclate) capsule
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Safety and Efficacy of WC2031 Versus Vibramycin for the Treatment of Uncomplicated Urogenital Chlamydia Trachomatis Infection: A Randomized, Double-blind, Double-dummy, Active-controlled, Multicenter Study

Primary Outcome Measures:
  • Microbiological Cure Rate [ Time Frame: Day 28 ]
    Percentage of Subjects in mITT Population with Microbiological Cure defined as a negative result for C. trachomatis as determined by GP AC2 NAAT (Gen-Probe Aptima Combo 2 Nucleic Acid Amplification Test) at Day 28

Secondary Outcome Measures:
  • Microbiological Cure and Clinical Cure of C. Trachomatis, Day 28, Clinically Evaluable Population, Percentage Participants Cured [ Time Frame: End of Study (Day 28) ]
    Microbiological cure (defined as a negative result for urogenital C. trachomatis, determined by GP AC2 NAAT/Gen-Probe Aptima Combo 2 Nucleic Acid Amplification Test and clinical cure (for males defined as resolution of baseline signs/symptoms of dysuria, urethral pruritus and urethral discharge, and resolution of exam finding of urethral discharge; for females resolution of exam finding of endocervical discharge) at Day 28

  • Microbiological Cure C. Trachomatis and M. Genitalium, M. Genitalium Coinfected Population, Day 28, Percentage Participants Cured [ Time Frame: End of Study (Day 28) ]
    Percentage Subjects Cured of both M. genitalium and C. trachomatis M. genitalium co-infected population: microbiological cure for both at Day 28, defined as negative PCR (polymerase chain reaction) for M. genitalium and negative GP AC2 NAAT (Gen-Probe Aptima Combo 2 Nucleic Acid Amplification test) for C. trachomatis at Day 28

  • Microbiological Cure C. Trachomatis, N. Gonorrhoea Negative Population, Day 28, Percentage Participants Cured [ Time Frame: Day 28 ]
    Percentage Participants cured in N. gonorrhoea Negative Population: cured defined as both microbiological cure (negative result for urogenital C. trachomatis, determined by GP AC2 NAAT/Gen-Probe Aptima Combo 2 Nucleic Acid Amplification test) and clinical cure (males defined as resolution of baseline signs/symptoms of dysuria, urethral pruritis and urethral discharge, and resolution of exam finding of urethral discharge; females - resolution of exam finding of endocervical discharge) at Day 28
