This is a Phase 3, multi-center, prospective, randomized, placebo-controlled, delayed treatment, double-blind, study to evaluate the effectiveness, and safety of a single, oral dose of Solosec® containing 2 grams of secnidazole in female patients with trichomoniasis.

The study will consist of a primary study phase (Visit 1 (baseline) to Visit 2 (Day 6-12)) and a follow-up phase (Visit 2 to Visit 3 (7-12 days post Visit 2)). During the primary phase patients will be randomly assigned in a 1:1 ratio to either Solosec or placebo. Patients will return to the clinic for the "test of cure" (TOC) visit to be conducted on Days 6-12 (Visit 2).

To ensure all patients receive treatment and to maintain the double-blind, after completion of the primary phase, patients will receive the opposite treatment , (placebo patients will receive Solosec and vice versa). Patients with V2 cultures that are subsequently positive for T. vaginalis will return to the clinic for Visit 3 (V3) assessments and investigator assessment of need for additional therapy (an additional Visit 4 may be scheduled at the investigator's discretion if culture at V3 is positive).

Summary of results includes data reported during the primary phase of the study [Visit 1 (baseline) to Visit 2/TOC (Day 6-12)]

Inclusion Criteria:

• adult female or post-menarche adolescent girl ≥12 years of age in general good health

• Have a diagnosis of trichomoniasis at the screening visit as determined by one of the following:

  • positive T. vaginalis NAAT test within 30 days of screening for which treatment has not been initiated.
  • positive OSOM® rapid test.
  • positive wet mount assessment.

• Agree to abstain from vaginal intercourse until the final study visit

• Agree not to have any vaginal penetration or use of any vaginal products for the duration of the study

Exclusion Criteria:

• Are pregnant, lactating, or planning to become pregnant during the study.
• Are suspected clinically (or confirmed diagnostically) of having alternative causes of vaginal symptoms including symptomatic vulvovaginal candidiasis, chlamydia, gonorrhea, or an active genital herpes outbreak
• Are suspected clinically of having an acute urinary tract infection.
• Have active genital lesions, including primary syphilitic chancres and herpes simplex virus lesions, or other vaginal or vulvar conditions which could confound the interpretation of the clinical response, as determined by the Investigator (patients with genital warts may be enrolled).
• Have received systemic antibacterial therapy or topical antimicrobial/antifungal/ immunomodulatory therapies in the genital area (vagina, vulva and surrounding soft tissue), within 14 days prior to the Baseline Visit (Day 1).

All IPD that underlie results in a publication

After publication of the primary study results, the research team will prepare final research data files that may be shared with other investigators, upon request.

Requests for research data must be submitted to author CAM in writing, via a standard data request form, with a justification for how the data will be used. Author CAM and Lupin Pharmaceuticals will review all requests for research data obtained from this study. The mechanism by which the data will be made available to investigators will follow all NIH guidelines for data sharing as they evolve. At a minimum this would consist of a data use agreement that provides for commitments to use the data for research purposes only, secure the data with appropriate computer technology, obtain IRB approval, and destroy (or return) the data after analyses are complete.

Safety Population

Data includes AEs reported during the primary phase of study [Visit 1 (baseline) to TOC/Visit 2 (day 6-12)] for each study patient.

Adverse Event data reported for primary phase of study only. Subjects received either Solosec or Placebo (1:1) during primary phase of study.
