Parkinson's Disease (PD) Clinical Trial
Official title:
Effect of Three Multiple-dose Regimens of BIA 9 1067 at Steady-state on the Levodopa Pharmacokinetics of a Single-dose of Immediate Release 100/25 mg Levodopa/Carbidopa and 100/25 mg Levodopa/Benserazide in Healthy Subjects
The purpose of this study is to determine the effect of BIA 9 1067 (5 mg, 15 mg and 50 mg) in steady-state conditions on the levodopa pharmacokinetics of a single dose of immediate-release levodopa/carbidopa 100/25 mg and of a single dose of immediate-release levodopa/benserazide 100/25 mg.
A single-centre, randomized, double-blind, gender-balanced, placebo-controlled study in 4 groups of 18 healthy subjects each. This study consisted of a once-daily administration of BIA 9 1067 (5 mg, 15 mg or 50 mg) or placebo for 18 days. Twelve (12) hours after the BIA 9 1067 dose, a single-dose of levodopa/carbidopa 100/25 mg was administered on Day 11 and a single-dose of levodopa/benserazide 100/25 mg was administered on Day 18. ;
Allocation: Randomized, Endpoint Classification: Pharmacokinetics Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment
