This protocol details a Phase 1, randomized, placebo-controlled, single-blind, dose escalation study to determine the safety, tolerability, and PK profile of SRT3025 in healthy male subjects. The study will be conducted in two parts. In Part 1A, 6 Cohorts of subjects will receive single escalating doses of SRT3025. In Part 1B, an additional one to two cohorts may be enrolled to investigate the effect of a moderate fat/calorie meal on single dose PK endpoints. In Part 2A, up to three cohorts may be enrolled to receive 14-day repeat doses of SRT3025 chosen from the Part 1A safety, tolerability, and PK data. In Part 2B, one to two additional cohorts may receive 14-day repeat doses of SRT3025 in combination with a moderate fat/calorie meal.
