Bitop AG194 enrolled

Overview

The aim of this multicentre, actively controlled, randomized, open label, parallel group, prospective, comparator study is to collect data on the clinical effectiveness and tolerability of the medical device ERS09 compared to a well-established comparator spray in the symptomatic treatment of sore throat due to acute pharyngitis and dry cough.

The aim of this study is to collect data on the clinical effectiveness and tolerability of Ectoin® Mouth and Throat Spray Althaea Honey (ERS09) compared to the well-established comparator spray EMSER® Hals- und Rachenspray (both medical devices) in the symptomatic treatment of sore throat due to acute pharyngitis and dry cough. The principle mode of action of ectoine is based on the physical interaction of the compatible solute with water and the resulting stabilizing effects of the ectoine hydro complex on the epithelial tissue treated. Althaea has so-called mucilaginous effects, that means generally a shielding of the irritated mucus membranes by thin polysaccharide layers. Such mucilaginous polymer layers lead to rehydration, coating of peripheral sensory receptors, and therefore to a reduction of throat irritation and dry coughing. Honey acts predominantly as demulcent with its viscous liquid constitution based on mainly fructose and glucose. The combination of all three substances may result in a multi-modal treatment of the symptoms of sore throat and dry cough. Patients will be randomly assigned to one of the following treatment groups: * treatment with ERS09 * treatment with comparator (EMSER® Hals- und Rachenspray) Patients' symptoms will be documented by the physician in investigator questionnaires at visits 1, 2 and 3. At visit 1 the patients will receive a patient diary for daily documentation of their symptoms. In addition, patients and investigators will be asked to evaluate the overall effectiveness and tolerability of ERS09 spray at visit 3.
