Brief Summary:
The purpose of this study is to determine the safety, efficacy and pharmacokinetics following administration of CVT-301 in treatment of "off" episodes in Parkinson's Disease patients.

Condition or disease Intervention/treatment Phase
Idiopathic Parkinson's Disease Drug: CVT-301 Drug: Placebo Drug: Sinemet (carbidopa/levodopa) Phase 2

Detailed Description:
Treatment options for patients with motor response fluctuations are limited. Most commonly, "off" episodes are managed by adjusting the dose interval of their standard oral medications or by self-administration of unscheduled doses of oral Parkinson's medication. Due to the variability in levodopa absorption following oral dosing, resumption of motor function is unreliable and may be delayed for an hour or more. CVT-301 delivers levodopa using a simple inhaler, resulting in rapid increases in levodopa blood levels and is expected to result in rapid restoration in motor function for patients experiencing "off" episodes.
