Brief summary
A study evaluating the effects of food intake on the pharmacokinetic (PK) profiles of TGRX-678
Detailed description
This study is designed as single-center, single-dose, randomized, open-label and parallel-comparison to evaluate food effect on PK profile of TGRX-678 in healthy subjects. Safety and tolerability of the drug is also evaluated during study.
