Clinical Evaluation of MucoPEG™ for Xerostomia (CEMPEG)

The purpose of this study is to evaluate the effectiveness of the oral rinse comparing to MucoPEG™ and Biotene®.

This is a randomized open-label crossover study with 42 patients receiving treatment. Patients will be randomly assigned to receive either the MucoPEG™ or the Biotene® Dry Mouth Gentle Oral Rinse in the first period. Patients will use the assigned oral rinse two times a day for two weeks. Patients will switch to the other treatment after a wash-out period of one week.

Study Overview

• Status: Completed
• Conditions: Xerostomia; Dry Mouth
• Intervention / Treatment: Device: MucoPEG; Device: Biotene

Detailed Description

The purpose of this study is to compare MucoPEG™ and it temporal change to those of the Biotene® Dry Mouth Gentle Oral Rinse in patients with Xerostomia. The study will gather data on patient reported outcomes on the safety and performance of the product, mouth-feel qualities and any changes in dry mouth.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Visual Analogue Scale (VAS)	To demonstrate the effectiveness of MucoPEG is better than that of Biotene Dry Mouth Gentle Oral Rinse in relieving xerostomia. Effectiveness will be addressed using the Visual Analogue Scale (VAS). (VAS), where 0 is "Not Dry at All" and 10 is "Very Dry"	Prior to product use, first day of treatment period, after the last dose of the product used and on the final day of treatment period.
Dry Mouth Relief Questionnaires (DMRQ)	To demonstrate the effectiveness of MucoPEG is better than that of Biotene Dry Mouth Gentle Oral Rinse in relieving xerostomia. Effectiveness will be addressed using the Dry Mouth Relief Questionnaires (DMRQ).	2 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Product Use Questionnaire (PPUQ)	To demonstrate effectiveness of MucoPEG in treating symptoms of dry mouth to that of Biotene. Effectiveness will be assessed using dry mouth Product Use Questionnaire (PPUQ).	2 weeks
Product Performance and Attributes Questionnaire (PPAQ)	To demonstrate effectiveness of MucoPEG in treating symptoms of dry mouth to that of Biotene. Effectiveness will be assessed using dry mouth Product Performance and Attributes Questionnaire (PPAQ)	2 weeks
Number of participants with treatment-related adverse events as evaluated by the Principal Investigator	To evaluate the clinical safety of MucoPEG. Patient reported outcomes will be evaluated by the Principal Investigator.	2 weeks
Change in Xerostomia using the Dry Mouth Inventory (DMI) questionnaire.	To examine change in Xerostomia using the Dry Mouth Inventory (DMI). Using a scale from "Disagree (0)" to "Strongly agree (3)"	2 weeks
Visual Analogue Scale (VAS)	To assess the effectiveness of MucoPEG in relieving xerostomia. Effectiveness will be addressed using the Visual Analogue Scale (VAS). Where 0 is "Not Dry at All" and 10 is "Very Dry"	2 hours and 1 week of use
