Clinical Trial Summary

It is an open-label, balanced, randomized, five-treatment, five-period, five-sequence, multiple oral dose, crossover comparative bioavailability study of different strengths of carbidopa/levodopa extended-release tablets with carbidopa and levodopa tablets in normal, healthy adult human subjects under fasting and fed conditions. The primary objective of the study is to compare the pharmacokinetic profiles between WD-1603 extended-release formulations and carbidopa and levodopa tablets 25mg/100mg following three times a day after oral administration in fasting and fed conditions in healthy subjects and to compare relative bioavailability between treatments.

Clinical Trial Description

Study WD-1603-1005 is to compare the fluctuation index between WD-1603 extended-release formulations and Carbidopa and Levodopa Tablets following three times a day oral administration and the food effect on the initial absorption of levodopa in the morning in healthy subjects. At least 15 subjects will be enrolled at the beginning of the study and the order of receiving the Treatment A, B, C, D & E for each subject during all the periods of the the study will be determined according to a randomization schedule. ;
