Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Comparing the fluorescence signatures from mouthwash samples of patients with laryngopharyngeal reflux (LPR) and healthy volunteers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators aim to test if the biosensing platform Pandra, developed by Rosa Biotech, may be suitable to distinguish patients with LPR symptoms, both with and without objective evidence of gastroesophageal reflux disease (GORD), vs healthy volunteers due to their expected inflammation and cell changes in the laryngo-pharyngeal region. The investigators intend to analyse 20 samples of mouthwash solutions from each of the following groups:

A. Patients with symptoms of LPR and objective evidence of GORD B. Patients with symptoms of LPR and no objective evidence of GORD C. Healthy volunteer group
