Primary Outcome Measures:
  • Phase A (first 12 patients): subjective sialorrhea visual-analog scale. Phase B: sialorrhea visual-analog scale and objective saliva measurement (measured with a cotton roll). [ Time Frame: Phase A: every 15 minutes for 2 hours. Phase B: same as Phase A + one objective saliva measurement at a time point to be determined in the interim analysis. ] [ Designated as safety issue: No ]

Estimated Enrollment: 36
Study Start Date: March 2008
Estimated Study Completion Date: April 2009
Estimated Primary Completion Date: March 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Crossover Drug: Crossover of placebo, 0.3, 1 or 3 mg of tropicamide.
Mucoadhesive film containing placebo, 0.3, 1 or 3 mg of tropicamide.
Other Name: crossover

Detailed Description:

NH004 contains the anticholinergic agent tropicamide and is delivered in a convenient product form (intra-oral dissolvable thin films) designed for the management of sialorrhea. This study is a double blind, placebo-controlled, crossover study of the safety and potential efficacy of three doses of of NH004 films for the short-term relief of the symptoms of sialorrhea in Parkinson's disease patients.

A total of 36 Parkinson's disease patients will be enrolled in the study in two Phases. Phase A will include 12 patients and Phase B up to 24 patients. There will be an interim analysis after conclusion of Phase A. In both phases patients will be randomized into one of four groups. Each group will have a distinctive sequence for receiving intra-oral dissolvable films of 0.3 mg, 1 mg, 3 mg of NH004, or placebo during four visits.
