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:

Official Title

A Multicenter, Randomized, Active-controlled, Double-blind, Double-dummy, Parallel Group Study of the Efficacy, Safety, and Tolerability of Continuous SC ND0612 Infusion vs. Oral IR-LD/CD in Subjects With PD Experiencing Motor Fluctuations


This is a phase III multi-center, randomized, active-controlled, double-blind, double-dummy, parallel group clinical trial, investigating the efficacy, safety, and tolerability of continuous subcutaneous ND0612 infusion in comparison to oral IR-LD/CD in subjects with Parkinson's disease experiencing motor fluctuations.

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.
