Clinical Trial Summary

This study are (1) to assess the relative bioavailability (BA) of a single oral dose of either 5 mg of Levamlodipine Maleate Tablets from CSPC or 10 mg of Amlodipine Besylate Tablet (NORVASC®) from Pfizer Inc. under fasting condition in male and female healthy subjects; and (2) to evaluate food effect on the PK profile of Levamlodipine Maleate Tablets from CSPC.

Description:

This study consists of 2 parts: Part 1 will be a randomized, open-label, single-dose, two-way crossover study to assess the relative BA of levamlodipine maleate tablets from CSPC (Test) versus Amlodipine Besylate Tablet NORVASC® from Pfizer Inc. (Reference) after a single oral administration under fasted conditions in male and female healthy subjects. Approximately 32 healthy subjects will be enrolled in the US to obtain 27 completed subjects. Part 2 will be a single-arm, open-label, single-dose phase to assess food effect on the PK profile of levamlodipine maleate tablets from CSPC. Subjects who have completed Part 1 will be rolled over to Part 2 after a wash-out period for at least 14-days since the last dosing. Subjects will receive a single oral administration of study drug under a high-fat / high-calorie meal that should derive approximately 150, 250 and 500-600 calories from protein, carbohydrate and fat, respectively.
