Clinical Trial Summary

The purpose of this study is to evaluate the effect of EVP-6124 at therapeutic and supratherapeutic concentrations on cardiac repolarization in healthy subjects.

Description:

Subjects will be randomized to six treatment sequences of 10 subjects each. Subjects will be admitted to the clinic on Day -1 before dosing. Each of the EVP-6124 and placebo treatment periods (blinded) will include a 10-day/9-night confinement to the Clinical Pharmacology Unit (CPU) with study drugs being administered on Day 1 and Day 2. The moxifloxacin treatment period (open-label) will include a 3-day/2-night confinement to the CPU with moxifloxacin administration on Day 1.

The study will include 2 washout periods in which each washout starts from the time of the last dose of the preceding treatment period to the first dose of the next treatment period. The washouts following the EVP-6124 or placebo treatments will be 30 days while the washout following the moxifloxacin treatment will be 7 days. Follow-up visit (5 to 10 days following discharge from the CPU).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change-from-baseline in individual corrected QTc (?QTcI) for EVP-6124 vs. placebo	Change-from-baseline in Fridericia's correction QTc (?QTcF) and change-from-baseline in Bazett's correction QTc (?QTcB) will be secondary variables.; The placebo-corrected baseline-adjusted QTc (??QTc), calculated as differences between time-matched mean change-from-baseline QTc values obtained on Day 1 (low dose) and on Day 2 (high dose) of the EVP-6124 treatment relative to the corresponding QTc values obtained on Day 1 and Day 2 of the placebo treatment, will be evaluated to quantify the effect of EVP-6124 on cardiac repolarization.	Day 1: predose to 20 hours postdose; Day 2 predose to 168 hours postdose	Yes
Secondary	Change-from-baseline in individual corrected QTc (?QTcI) for positive control vs. placebo	The placebo-corrected baseline-adjusted QTc (??QTc), calculated as differences between time-matched mean change-from-baseline QTc values obtained on Day 1 of the moxifloxacin treatment relative to QTc values obtained on Day 1 of the placebo treatment, will be evaluated to establish assay sensitivity.	Day 1: predose to 20 hours postdose	No
Secondary	Safety and tolerability of EVP-6124 at low dose and high doses	All AEs (adverse experiences) spontaneously reported by subjects and/or observed by investigator and evaluation of physical examinations, prior and concomitant medications, clinical laboratory tests, ECGs, and vital signs measurements.	Day -1 through follow-up (5 to 10 days after discharge)	Yes
