Clinical Trial Summary

A single-center, randomized, double-blinded, placebo parallel controlled phase 1 study to evaluate the safety and pharmacokinetics/pharmacodynamics of multiple (6 days) ascending dose (20mg QD, 40mg QD, 20mg Bid) administrationof Anaprazole in healthy Chinese subjects. 36 subjects, 12 subjects for each dose group. In each dose group, 10 subjects take anaprazole, 2 subjects take placebo.
