Study Summary

The study is designed to meet regulatory requirement outside the US. The dosing regimen and assessments timepoints were dictated by immediate release (IR) guaifenesin (GGE) and do not match approved Mucinex labeling in the U.S. The purpose of this study is to determine whether Mucinex is effective and non-inferior as compared to placebo and immediate release guaifenesin in the treatment of symptoms of acute upper respiratory infections. This design was required based on EU regulatory guidance.

Primary Outcome

Participants completed diary cards twice a day that asked questions about their cough and phlegm status. The Daily Cough and Phlegm Diary Card consisted of eleven questions, eight core questions plus three questions that were answered dependent upon the response to core questions. The SUM8 consisted of the sum of the answers to the eight core questions. Each question was answered on a scale of 0-4, with 4 representing the greatest severity of symptoms. The SUM8 thus had a scale range of 0-32 wit
