  Purpose

This is a randomized, open-label, rater-blinded, multicenter, 3-treatment, 3 period, single-dose crossover study. Approximately 51 qualified immediate-release (IR) CD-LD-experienced advanced Parkinson's disease patients will be randomized to 1 of 3 dosing sequences.

Objectives:

  • Assess the pharmacodynamics and pharmacokinetics (PK) of IPX203 (carbidopa and levodopa) in subjects with advanced Parkinson's disease.
  • Characterize the safety of IPX203 in subjects with advanced Parkinson's disease.

Condition Intervention Phase

Primary Outcome Measures:
  • "Off" time per the Assessment of Subject's Motor State [ Time Frame: Up to 10 hours ]

Secondary Outcome Measures:
  • Duration of effect estimated using the timepoint at which an improvement of at least 4 points in the MDS-UPDRS Part III score from predose is first observed and continuing until the timepoint at which the improvement is no longer observed [ Time Frame: Up to 10 hours ]
  • Change from predose value in the number of finger-taps at each timepoint [ Time Frame: Up to 10 hours ]

Other Outcome Measures:
  • Number of Participants with Adverse Events [ Time Frame: Screening through end of study approximately 6 weeks per subject ]
  • Maximum concentration (Cmax) [ Time Frame: Up to 10 hours ]
  • Area under the curve (AUC) [ Time Frame: Up to 10 hours ]

Detailed Description:

IPX203 contains two different drugs called levodopa and carbidopa in one capsule.

  • levodopa turns into a material called 'dopamine' in your brain. The dopamine helps to improve the symptoms of your Parkinson's disease.
  • carbidopa belongs to a group of medicines called 'aromatic amino acid decarboxylase inhibitors'. It helps levodopa work more effectively by slowing the speed at which levodopa is broken down in your body.
