Details and patient eligibility

About

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.

Full description

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)]
