Efficacy, Safety and Tolerability Study of ND0612 vs. Oral IR-LD/CD in Subjects With PD Experiencing Motor Fluctuations

This is a multi-center, randomized, double blind, active controlled clinical Study. Following a screening period, eligible subjects will be enrolled to an open-label oral IR LD/CD adjustment period; then an open-label ND0612 conversion period; then after optimization periods subjects will be randomized to receive either ND0612 or its matching Placebo with IR LD/CD. Subjects can continue to an optional open-label extension period for one year; To contact US site near you should go to: www.BouNDless-Study.com

This study is comprised of 6 periods: 1. a Screening Period; 2. an open-label oral IR-LD/CD Adjustment Period. 3. an open-label ND0612 Conversion Period. 4. a randomized, double-blind, double-dummy, active-controlled Maintenance Period. 5. an optional open-label Treatment Extension; and 6. a Safety Follow-up Period.
