Study Description
Brief Summary:
The overall goal of this project is to determine the influence of patient treatment and host factors on repeat Trichomonas vaginalis (TV) infections among HIV-negative women

Condition or disease Intervention/treatment Phase
Vaginitis Trichomonal or Due to Trichomonas Drug: MTZ 500 mg BID x 7 days Drug: MTZ 2 g Phase 3

Detailed Description:
This study is a phase III randomized clinical trial. HIV-negative women who test positive for TV at their routine gynecological exam at participating clinics will be referred to the nurse/study coordinator to screen for eligibility, provide a description of the study, and obtain written, informed consent (N=700). Subjects will undergo an audio computer assisted self- interview (ACASI), and will self-collect vaginal swabs for Trichomonas testing by InPouch and NAAT, Gram stain testing, and a future microbiome specimen. They will be randomized into one of two arms; metronidazole (MTZ) 2 g single dose (CDC recommended treatment regimen) or MTZ 500 mg BID 7-day dose (CDC alternative treatment regimen). All enrolled women will be scheduled for a follow-up visit at four weeks post treatment completion (window 3-13 weeks).
