Brief 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.
Detailed 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.
Interventions
In Part 1, this group of subjects were treated with a single dose of 5 mg levamlodipine maleate tablets (Test Product), then crossed over to receive a single dose of 10 mg Amlodipine Besylate Tablet NORVASC® (Reference Product) under fasted conditions. After a wash-out period for 14-days, all subjects were rolled over to Part 2 where they received a single dose of 5 mg levamlodipine maleate tablets under a high-fat/high-calorie meal to assess food effect.
