NOCOSSafety, Tolerability, Pharmacokinetics and Pharmacodynamic Effects of Single and Repeated Escalating Doses of ODM-103: a Randomised, Double-blind, Placebo- and Entacapone-controlled Single Centre First-in-man Study in Healthy Volunteers.

The study is divided into two parts. Part one is a crossover study where healthy volunteers will receive two doses of ODM-103 and one dose of placebo. Part II of the study is a multiple ascending dose parallel group study where healthy volunteers will receive ODM-103 three times daily for seven days. Healthy volunteers taking part in Part II of the study will also receive levo/carbidopa and entacapone four times daily on day 1 and levo/carbidopa in addition to ODM-103 on day 9. The study will also look at the pharmacokinetic(how the body handles the drug) and pharmacodynamics (how the drug affects the body) of ODM-103.
