The purpose of this study is to assess the safety and tolerability of ascending single oral doses of GAP-134 in healthy subjects, to provide the initial pharmacokinetic profile of the oral formulation of GAP-134 in healthy subjects, and to evaluate the effect on the pharmacokinetic profile of a high-fat meal of 450 mg of GAP-134 administered to healthy subjects.
Safety and tolerability will be evaluated from reported AEs, scheduled physical examinations, vital sign measurements, cardiac rhythm monitoring, 12 lead ECGs, and clinical laboratory test results. [ Time Frame: 2 months ]
Secondary Outcome Measures :
