Trial overview
The available study investigates SACCHAROMYCES CEREVISIAE TYPE D EXTRACT as a nasal spray in a pressurized container for people with acute rhinitis, rhinopharyngitis, and rhinosinusitis that do not require antibiotic therapy.[1]
The study compares the active spray with placebo, which is a look-alike treatment used for comparison.[1]
The trial is designed to see whether the spray can improve nasal and common cold-like symptoms over a short treatment period.[1]
Who can participate
The study includes female and male adults and paediatric participants over 6 years old.[1]
People in the trial must have one of the target conditions: acute rhinitis, rhinopharyngitis, or rhinosinusitis, and their illness must not need antibiotics.[1]
This means the study focuses on patients with upper airway symptoms that are being managed without antibiotic treatment.[1]
Study design and phase
This is a Phase 3 study, which means it is a later-stage clinical trial used to test how well a treatment works in a larger group of patients.[1]
The trial is prospective, controlled, randomized, double blind, two-arm, parallel-group, and multicentre.[1]
Prospective means the study follows people forward in time after they join the trial.[1]
Randomized means participants are assigned by chance to one of the study groups.[1]
Double blind means neither the participants nor the study team know who is receiving the study spray or placebo during the trial.[1]
Parallel-group means the two groups are treated at the same time so their results can be compared.[1]
Multicentre means the study is carried out in more than one study site.[1]
The brief study summary states that the spray was planned to be applied three times daily into each nostril for 7 days, compared with placebo.[1]
What is being measured
The main outcome is the change in nasal symptoms from the start of the study to Day 4, measured in the treatment group and the placebo group.[1]
The symptoms being tracked include nasal obstruction, rhinorrhea, thick mucus, sneezing, and cough.[1]
These symptoms are rated with the Common Cold Symptoms Severity Questionnaire (CCSS), which is a tool used to score how severe the symptoms are.[1]
The CCSS is assessed at Baseline (Day 1), Day 2, Day 3, Day 4, and Day 8, so the study can follow how symptoms change over time.[1]
Status and study size
The trial status is Authorised, showing that the study has been approved to proceed.[1]
The planned enrollment is 248 participants, which is the number of people the study aims to include.[1]
Because the study compares SACCHAROMYCES CEREVISIAE TYPE D EXTRACT with placebo in a defined patient group, it is focused on whether the spray improves symptoms better than no active treatment.[1]
