• Status: Completed
• Trial end date: 2001-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study was to determine the effect of 0.5% amlexanox oral rinse compared to a vehicle control on mucositis-related ulceration and erythema (objective score)and on mucositis-related oral pain (subjective score).

A secondary objective was to evaluate the safety of 0.5% amlexanox oral rinse by determining the frequency of treatment-emergent drug-related adverse events or clinical laboratory abnormalities.
