Official title

A Phase 1, Randomized, Double-blinded, Four-period Crossover, Thorough QT/QTC (TQT) Clinical Trial to Evaluate the Effect of Zoliflodacin on Cardiac Repolarization in Healthy Male and Female Subjects

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The Phase I Thorough QT/QTc (TQT) study will be performed in a single center, the Vince \& Associates Clinical Research, Inc., clinical trials unit (CTU), in 72 healthy male or female subjects, aged 18 to 45 years inclusive, to evaluate the effect of zoliflodacin on the corrected QT interval of the electrocardiogram (ECG) using Fridericia's Formula (QTcF) and other ECG parameters; the correlation of the drug concentrations (and pharmacokinetic (PK) profile) with time-matched, placebo-corrected, baseline-adjusted difference in QTcF interval (delta delta QTcF); and the PK and safety profiles of the new zoliflodacin formulation. Each subject will receive one dose of each of four treatments: zoliflodacin 2 g orally, zoliflodacin 4 g orally, placebo for zoliflodacin 4 g orally, and moxifloxacin 400 mg orally. The study will last approximately 12 weeks with a subject participation duration of up to 55 days. The primary hypothesis to be tested is that following administration of zoliflodacin 2 g and 4 g, the upper bound of the one-sided 95% confidence interval (CI) of treatment effect on delta delta QTcF is \> / = 10 msec for at least one of the ECG assessments, against the alternative hypothesis that all mean effects are \< 10 msec. The primary objective is to evaluate the effect of zoliflodacin on the corrected QT interval of the ECG using Fridericia's formula (QTcF).
