Phase I Study of Direct Coagulation Factor Xa Inhibitor SYHA136 Tablets in Chinese Healthy Volunteers
Single-center, Randomized, Double-blind, Placebo-controlled, Single Dose Ascending Trial of SYHA 136 Tablets in Healthy Subjects
The trial used single-center, randomized, double-blind, placebo-controlled, single-dose ascending study.
The trial planned to enroll fifty-six healthy volunteers. The subjects were allocated to eight dose groups, including 0.5 mg (3+1), 1 mg (3+1), 2.5 mg (6+2), 5 mg (6+2), 10 mg (6+2), 20 mg (6+2), 35 mg(6+2) and 50 mg (6+2). Each dose group was allocated test drugs and placebos according to the proportion of subjects in the brackets mentioned above.
