Design outcomes

Primary

MeasureTime frame
Secondary Objective: None;Main Objective: To assess the effect of Caphosol® oral rinse on clinical outcomes of selected oral symptom burden (oral mucositis/stomatitis (aphthous-like), oral pain, taste change (dysgeusia), difficulty swallowing (dysphagia), difficulty oral intake, and dry mouth) associated with incidence of grade = 1 oral adverse events and the anticancer therapy cessation in patients treated with selected targeted anticancer therapy in selected tumors.;Primary end point(s): Assess the severity of patient-reported oral adverse events as determined by the change in the VHNSS2.0 score 3 times a week, from onset of oral mucositis, stomatitis (aphthous-like), oral pain, taste change (dysgeusia), difficulty swallowing (dysphagia), difficulty oral intake, or dry mouth during the active oral rinse period with Caphosol® oral rinse versus NaCl 0.9% oral rinse, 4 times daily, 2 minutes with 30 ml solution
