PRIMARY outcome

Timeframe: During 11 days post administration of a single oral dose of P218 to healthy volunteers

Population: In Part A, forty-two subjects received P218 at single doses of 10, 30, 100, 250, 500, 750 or 1000 mg and 14 subjects received placebo (two each per dose level). In Part B, four subjects received a single dose of 250 mg when fasted in Period 1 and fed in Period 2, four other subjects received 250 mg when fed in Period 1 and fasted in Period 2.
