This is a phase 1, single-center, randomized, double-blind, placebo-controlled, single-dose escalation study to evaluate the safety, tolerability, and pharmacokinetics profiles of TG-1000 in healthy volunteers, and to evaluate the food effect on pharmacokinetics of single oral dose of TG-1000 in healthy volunteers. The study will be divided into two parts.
Part A is designed as randomized, double-blind, placebo-controlled, sequential, single ascending oral dose to evaluate the safety, tolerability, and PK profiles of TG-1000 in healthy volunteers.
Part B is designed as randomized, open-label, two treatment (fasted vs. fed), two-period, two-sequence crossover to compare the effects of food on the PK of single oral dose of TG-1000 in healthy subjects.
