Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of ODM-103 in Healthy Volunteers

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the safety and tolerability of escalating doses of ODM-103 when given to healthy male volunteers.

Detailed Description
-----------------
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.
