This is a randomized, blinded, placebo and active-controlled, 4-period, crossover design thorough QT/QTc (TQT) study to evaluate the effect of ABBV-CLS-7262 on cardiac repolarization in healthy adult subjects.
This is a Phase 1, randomized, double-blind (except for moxifloxacin), placebo- and positive-controlled, single-site, 4-way crossover study to investigate the effects of single therapeutic and supratherapeutic IV doses of difelikefalin (CR845) on the QTc interval in healthy adult subjects. Subjects will be randomized to a treatment sequence consisting of 4 treatment periods with a minimum 5-day washout between treatments. Subjects will receive each of the study treatments over the course of the study. Randomized subjects will receive the assigned study treatment as a single dose in the fasted state in the morning on Day 1 of each treatment period.
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).
The study designed to determine the effect induced by WCK 2349 on the QT interval. The study will be conducted in two parts: 1) to determine the supratherapeutic dose; and 2) to assess the safety of high doses of single-dose administration of WCK 2349 on the QT interval.
This is a single-center, randomized, double-blind crossover study with four treatments, four periods and four sequences to investigate the effects of orally administered pomalidomide on QT interval. The study will be conducted in healthy male subjects. Pomalidomide (clinically indicated dose for multiple myeloma \[MM\] as per the United States Package Insert \[USPI\] of 4 mg and supratherapeutic dose of 20 mg) and placebo treatments will be double-blinded. Moxifloxacin (positive control) will be administered in an open-label fashion to determine the sensitivity of the assay. The core electrocardiogram (ECG) laboratory and ECG readers will be blinded to all study treatments and sequences.
The objective of this study is to evaluate the effect of repeat oral dosing of ASP1941 on electrocardiogram (ECG) measurements.
* Determine whether VI-0521 has an effect on the electrical activity of the heart in healthy subjects. * Find out how much VI-0521 is in the blood and any potential side effects on ECG's of healthy subjects after taking the study drugs.
