Safety and Efficacy Study of NH004 Films for Relief of Sialorrhea Symptoms in Parkinson's Disease Patients (NH004-2)

September 22, 2015 updated by: NeuroHealing Pharmaceuticals Inc.

A Two-Phase, Double Blind, Placebo-Controlled, Randomized, Crossover Study of the Safety and Efficacy of Intra-Oral NH004 Films for the Short-Term Relief of Sialorrhea Symptoms in Parkinson's Disease Patients

The primary goal of the study is to evaluate the safety and potential efficacy of intra-oral dissolvable NH004 films to improve the short-term symptoms of sialorrhea (drooling) in Parkinson's disease (PD) patients.

Study Overview

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 up to 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.

  4. Patients who are receiving the following drugs: tricyclic antidepressants, Monoamine Oxidase Inhibitors (MAOI's), neuroleptics (antipsychotics), or anticholinergics.
  5. Patients who have taken any of the drugs mentioned in exclusion criteria number 4 within the last week.
  6. Patients with hypersensitivity to atropine or other anticholinergic drugs.
  7. Patients who have experienced adverse effects as a result of taking anticholinergic drugs.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Sialorrhea Visual Analogue Scale (VAS)
Time Frame: Before and 120 min after treatment administration
Saliva buccal assessment was evaluated by an VAS scale before, and 15, 30, 45, 60, 90, and 120 min after treatment administration. Subjects were asked to rate how much saliva they perceived in their buccal cavity on an unmarked 0 to 10 cm line, higher scores meaning greater perceived buccal saliva levels.
Before and 120 min after treatment administration

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage Change in Saliva Volume
Time Frame: Before and 75 minutes after treatment administration
Saliva volume was measured at baseline and 75 minutes after treatment administration. Volumes were measured by using cotton rolls placed near each Stenton duct and below the tongue for 5 minutes; cotton rolls were centrifuged and the volume of saliva determined.
Before and 75 minutes after treatment administration
