THOROUGH QT/QTc STUDY TO EVALUATE THE EFFECTS OF ECOPIPAM (EBS-101) ON CARDIAC REPOLARIZATION
- Detailed Description
This is a single-center, randomized, partially double-blind (open-label moxifloxacin), placebo- and positive-controlled, 4-way crossover study in healthy subjects. Following a 28 day screening period, eligible subjects will enter the clinical research unit (CRU) on Day -1. A total of 32 subjects will be randomized in a 1:1:1:1 ratio to 1 of 4 treatment sequences (8 subjects per treatment sequence). Subjects will receive the assigned study drug as a single oral dose in the morning on Day 1 of each treatment period (Day 1 \[Period 1\], Day 8 \[Period 2\], Day 15 \[Period 3\], and Day 22 \[Period 4\]) after an overnight fast. Subjects will have serially matched blood samples (for determination of plasma concentrations) and 12-lead ECGs collected at predose and up to 48 hours after each dose for C QTc analysis. Subjects will be discharged from the CRU 96 hours after the last dose of the study drug (Day 26). A follow-up telephone call will occur 5 ±2 days after discharge (Day 31 ±2).
