NCT02271503

Brief Summary

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.

You may qualify if:

  • Male or female subjects diagnosed with idiopathic PD with motor complications, who are currently being treated chronically with stable regimens of CD-LD.
  • Requiring at least 400 mg but not more than 1600 mg LD per day during the waking hours; and at least 100 mg but not more than 250 mg LD from IR CD-LD for the first morning dose.
  • Dosing frequency of IR CD-LD of at least 4 times daily excluding nighttime dosing.
  • Have an average of at least 2 hours per day "off" time during the waking hours and at least 1 hour "off" time per day, based on the PD diary collected for 3 consecutive days prior to Visit 1.

You may not qualify if:

  • Have used first morning dose of controlled-release (CR) CD-LD or Rytary for at least 4 weeks prior to Visit 1.
  • Female subjects who are currently breastfeeding or lactating.
  • Had prior functional neurosurgical treatment for PD (ablation or deep brain stimulation) or if such procedure(s) are planned or anticipated during the study period.
  • Allergic to study drugs
