Study of the Safety and Efficacy of Tropicamide Thin Films to Reduce Hypersalivation in Parkinson's Patients

Phase 2
Completed
Conditions
Sialorrhea (Excessive Drooling)
Interventions
Drug: NH004 Placebo
Registration Number
NCT01844648
Lead Sponsor
NeuroHealing Pharmaceuticals Inc.
Brief Summary

To study the safety and efficacy of tropicamide 1 mg intra-oral slow dissolving muco-adhesive thin films compared to placebo to reduce hypersalivation in PD patients manifesting sialorrhea complaints.

Detailed Description

This is a double-blind, placebo-controlled, randomized, crossover, multicentre study comparing intra-oral slow dissolving muco-adhesive thin films containing tropicamide 1 mg or Placebo. Patients will receive each treatment twice daily (1 h after breakfast and 1 h after lunch) for 1-week.

Patients will be evaluated for eligibility during the 14-day screening period. Those patients meeting all entry criteria at baseline will be randomized (1:1) to receive first tropicamide followed by placebo films or vice versa. Patients will return for regularly scheduled visits at Weeks 1 and 3 or at early discontinuation.

Primary Outcome Measures
NameTimeMethod
modified Teachers Drooling Scale (% responding)one week

The primary endpoint for this trial is the difference in responder rate between tropicamide and placebo. Responders will be defined as subjects whose mean sialorrhea score improved by at least 30% as compared to baseline in the 9-point modified Teachers Drooling Scale (mTDS).

Secondary Outcome Measures
NameTimeMethod
Visual Analg Scaleone week

Saliva buccal content as measured by a Visual Analog Scale (VAS) score, evaluated before and during 3 hours after treatments administration.

modified Teachers Drooling Scale (mean)one week

Difference in the mean sialorrhea scores between placebo and tropicamide in the 9-point modified Teachers Drooling Scale (mTDS).

Sialorrhea Clinical Scale for Parkinson's Disease (mean)one week

- Difference in the mean sialorrhea scores between placebo and tropicamide in the Sialorrhea Clinical Scale for Parkinson's Disease (SCS-PD).

UPDRS Part II sialorrhea item (mean)one week

Difference in the mean sialorrhea scores between placebo and tropicamide in the UPDRS Part II sialorrhea item (#6).
