Abstract:

AIM: To evaluate the bioequivalence and safety of the test formulation of daclatasvir hydrochloride tablets and the reference formulation of daclatasvir hydrochloride tablets (DAKLINZATM) in healthy Chinese subjects. METHODS: A single-dose, randomized, open-label, two-cycle, double-crossover design was used, and 60 healthy subjects were enrolled. The subjects were randomly divided into two groups, with 30 subjects in the fasting group and 30 subjects in the fed group. In the first cycle, one tablet (60 mg) of the test or reference formulation was taken orally as a single dose, and cross-administration was conducted on the 8th day. RESULTS: The main pharmacokinetic parameters of the test and reference formulations of daclatasvir hydrochloride tablets in the fasting group were as follows: Cmax (1 102.690±311.345) and (1 174.800±361.642) ng/mL; AUC0-t (13 517.051±3 576.349) and (13 503.448±4 022.914) h·ng·mL?1; AUC0-∞ (13 672.052±3 626.297) and (13 669.602±4 059.563) h·ng·mL?1. The main pharmacokinetic parameters of the test and reference formulations of daclatasvir hydrochloride tablets in the fed group were as follows: Cmax (791.733±230.334) and (872.000±303.921) ng/mL; AUC0-t (10 974.708±3 213.564) and (11 217.253±4 060.319) h·ng·mL?1; AUC0-∞ (11 140.018±3 261.934) and (11 396.162±4 143.077) h·ng·mL?1. The 90% confidence intervals for the geometric mean ratios of the main pharmacokinetic parameters (Cmax, AUC0-t and AUC0-∞) of daclatasvir in plasma after oral administration of 60 mg of the test and reference formulations of daclatasvir hydrochloride tablets under fasting and fed conditions fell within the 80.00%–125.00% equivalence interval. There were no serious adverse events in both groups. CONCLUSION: The test and reference formulations of daclatasvir hydrochloride tablets were determined to be bioequivalent and safe under fasting or fed conditions.
