NCT05128175

Brief 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.

Outcome Measures

Primary Outcomes (2)

  • Cmax of the pharmacokinetics of WD-1603 extended-release formulations and carbidopa and levodopa tablets 25mg/100mg from the morning of day 1 to the morning of day 2.

    To evaluate Cmax (Maximum Plasma Concentration) of the pharmacokinetics of 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.

    24 hours-from morning of Day 1 to morning of Day 2

  • The duration (hours) for the levodopa concentrations ≥ 50% of Cmax between WD-1603 extended-release formulations and carbidopa and levodopa tablets following three times a day orally administration in healthy subjects.

    To compare the duration (hours) for the levodopa concentrations ≥ 50% of Cmax, where maximum measured plasma concentration after 1st dose or 2nd or 3rd dose for each dose interval.

    24 hours-from morning of Day 1 to morning of Day 2

Interventions

For fasting conditions in the morning, a single oral dose will be administered to each subject under fasting conditions before 5 minutes of serving a standardized vegetarian breakfast as per the randomization schedule; for fasting conditions in the afternoon and evening, a single oral dose will be administered to each subject under fasting condition before 5 minutes of serving standardized vegetarian lunch and dinner as per randomization schedule. For fed condition, single oral dose will be administered to each subject after 30 minutes of serving standardized vegetarian breakfast, lunch and dinner as per randomization schedule. Dosing interval between two subsequent dosing should be 5 hours in each period. There will be one tablet for A, B, C, D and E.
