Brief Summary:
Ascending oral single-dose study to evaluate the safety and pharmacokinetics of TVB- 2640 tablets in the Chinese healthy population.

Condition or disease Intervention/treatment Phase
Healthy Drug: TVB-2640 Drug: Placebo Phase 1

Detailed Description:
This study is designed as a single-center, randomized, single-blind, placebo-controlled, single-dose escalation trial. The dose groups are 25 mg, 50 mg and 75 mg respectively. The next dose should be tested only if the previous dose has demonstrated to be safe and tolerated, and each subject will receive either the experimental drug or a placebo only once.
