A Clinical Trial Investigating the Short-term Relief of Symptoms of Acute Pharyngitis by Treatment With Three Different Doses of MYRAMISTIN™ Oromucosal Spray
- Registration Number
- NCT04470089
- Lead Sponsor
- Megainpharm GmbH
- Brief Summary
In this multi-center, randomized, placebo-controlled, double-blind stuy in which patients with acute pharyngitis will receive Myramistin™ / Placebo, which is provided as a spray. Patients will be randomised at Visit 1 on a 1:1:1:1 basis to one of the three MyramistinTM doses (0.005%, 0.01% and 0.02%) or placebo. The trial duration for an individual patient is 72 hours.
The primary objective is to evaluate the short-term efficacy of different MyramistinTM doses (0.005%, 0.01% and 0.02%) compared to placebo in the symptomatic treatment of acute pharyngitis.

- Primary Outcome Measures
Name Time Method Pain Intensity Differences 2 hours The primary endpoint is the Summed Pain Intensity Differences (SPID-2Pain), defined as Pain Intensity Differences (PID) summarized over the time course of 2 hours after first application on Day 1 (Baseline). The sum is calculated over the time-weighted differences from each measured time point to baseline after dosing using the 100mm Visual Analogue Scale (VAS) Sore Throat Pain Intensity Scale (STPIS).
- Secondary Outcome Measures
Name Time Method Time to Pain Relief 72+/-2 hours Time to 30% and 50% pain relief (30% and 50% reduction in STPIS) compared to baseline.
Tonsillo-Pharyngitis Assessment Scale 72+/-2 hours Change in Tonsillo-Pharyngitis Assessment (TPA) sum-score and single symptom scores from baseline to Visit 2 Variables (findings like e.g. oral temperature, oropharyngeal colour, size of tonsilles etc.) presented are rated using the values 0, 1, 2 or 3 (points). The points are added together to make a TPA that can range from 0 to 21 points. Pharyngitis is present if a total score of ≥6 is obtained.
Time to relief in Difficulty to Swallow 72+/-2 hours Time to 30% and 50% relief in difficulty in swallowing (30% and 50% reduction in DSS) compared to baseline.
Pain Intensity Differences 72+/-2 hours Pain Intensity Differences (PID) is summarized at different defined timepoints after first application on Day 1 (Baseline). The sum is calculated over the time-weighted differences from each measured time point to baseline after dosing using the 100mm VAS Sore Throat Pain Intensity Scale (STPIS).
Difficulty to Swallow Differences 72+/-2 hours SPID2-Swallow calculated analogously to the primary endpoint (including sensitivity analysis) using the Difficulty Swallowing Scale (DSS), furthermore it is calculated on different predefined timepoints.
Percentage of symptom free patients 72+/-2 hours * in throat pain at Visit 2 (STPIS=0)
* in difficulty in swallowing at Visit 2 (DSS=0)
* in throat pain and difficulty in swallowing at Visit 2 (STPIS=0 and DSS=0 - defined as complete
