About

The purpose of this study is to evaluate the clinical safety and effectiveness of Visco-ease dry mouth spray for the treatment of Radiotherapy Induced Xerostomia (RIX) in head and neck cancer patients. A parallel group double blind study design has been selected. The primary outcome is change in GRIX scores from baseline (visit 1) to end of treatment (visit 7). The primary outcome will be compared between Visco-ease and the placebo treatment.

Visco-ease
Experimental group
Description:
Visco-ease is a suspension of multilamellar vesicles comprising lipids in ratios which mimic the lipidic composition of endogenous extra-alveolar lamellar bodies. Visco-ease is suspended in physiological saline (0.9% NaCl) to provide a final dose concentration of 19.6 mg/mL. Visco-ease is a white to off-white turbid suspension. The device under evaluation in this clinical investigation is Visco-ease at a concentration of 19.6 mg/mL.
