First posted: 2013-06-10
Enrollment: 22
Sex: ALL
Minimum age (years): 18

Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: CROSSOVER
Primary purpose: TREATMENT

Brief summary: This study seeks to compare 4 known QT prolonging drugs versus placebo to determine their effects on electrophysiological and other clinical parameters. The underlying purpose is to determine if depolarization and repolarization effects caused by drugs with differing ionic channel mechanisms can be distinguished from one another, and to gauge the sensitivity and specificity of novel signal analyses for detection of depolarization and repolarization changes. Secondarily, to evaluate the exposure response relationship and drug induced effects on the heart rate biomarker relationship.

Detailed description: This will be a randomized, double blind, 5 way crossover research study in healthy male and female subjects, 18 to 35 years of age, to compare 4 known QT prolonging drugs versus placebo to determine their effects on electrophysiological and other clinical parameters. To maintain the study blind, subjects will be blindfolded during study drug administration. The cardiologists at the central ECG laboratory (Spaulding Clinical Research, LLC) will be blinded to treatment, time, and study day/subject identifiers.
