Bioequivalence Study of SAL001 and FORSTEO in Healthy Chinese Adults

Shenzhen Salubris Pharmaceuticals Co., Ltd.64 enrolled

Overview

This is a single-center, randomized, open label, single-dose, the original drug controlled, crossover design, two sequence, two periods, Phase Ⅰclinical study. 64 qualified subjects will be randomly assigned to two administration sequences (sequence A and sequence B) at the ratio of 1∶1, with 32 subjects in each sequence. Each period will be given subcutaneous injection once, and the washout period will be 72 hours, and each subject will be given subcutaneous injection twice. Sequence A: the test drug (SAL001) is injected in the first period, and the reference drug (FORSTEO) is injected in the second period. Sequence B: the reference drug (FORSTEO) is injected in the first period, and the test drug (SAL001) is injected in the second period. If the geometric mean ratio (GMR) 90% confidence interval of the major pharmacokinetic indexes (AUC0-t, Cmax) for SAL001 and FORSTEO is between 80.00% and 125.00%, the two drugs are considered to be bioequivalent.
