Primary Outcome Measures:
  • TV negative after treatment with either multi or single dose MTZ [ Time Frame: 4 weeks post treatment completion ]
    TV is assessed by nucleic acid amplification technique

Enrollment: 623
Actual Study Start Date: October 6, 2014
Study Completion Date: June 5, 2017
Primary Completion Date: June 5, 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: MTZ 2 g
Single dose MTZ
Drug: MTZ 2 g
MTZ 2 g
Other Name: Single dose MTZ
Experimental: MTZ 500 mg BID x 7 days
Multi dose MTZ
Drug: MTZ 500 mg BID x 7 days
MTZ 500 mg BID x 7days
Other Name: Multi-dose MTZ

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).
