Clinical Trial Summary

The objective of the study is to compare the bioavailability of a generic product of lisinopril with that of a reference product when administered to healthy volunteers under fasting condition. The test product is BF-Lisinopril Tablet 20mg (HK-63564) manufactured by Bright Future Pharmaceuticals Factory O/B Bright Future Pharmaceutical Laboratories Limited, and the reference product is Zestril Tab 20mg (HK-30515). The bioequivalence or bioinequivalence of the test and reference formulations will be assessed and concluded based on the plasma pharmacokinetic data of lisinopril, as well as WHO guidelines on registration requirements to establish interchangeability.

Description:

It is planned to enroll 16 to 30 healthy subjects, with an aim to obtain at least 12 evaluable subjects. The study design is a single-dose, two-treatment, two-period, two-sequence crossover with a washout period of one to two weeks. During each study session, the subjects will be administered a single dose of 20mg lisinopril (one BF-Lisinopril tablets 20mg or one Zestril Tab 20mg) after an overnight fast of approximately 10 hours. Venous blood samples will be collected at pre-dose (0h) and at 1,2,4,5,6,7,8,9,10,12,24 and 48 hours post-dose (13 time points). The plasma concentrations of lisinopril will be determined by a validated assay. The non-compartmental method will be used to analyze the plasma concentration-time data and calculate the main pharmacokinetic parameters such as Cmax, Tmax, AUC0-last, AUC0-inf, and T1/2. ANOVA will be calculated on logarithmically transformed Cmax, AUC0-last and AUC0-inf. The two one sided tests will be used to calculate the 90% confidence intervals for the mean difference in AUC0-last, AUC0-inf and Cmax and to assess the bioequivalence of the two products.
