Details and patient eligibility

About

The purpose of the clinical study is to evaluate efficacy of regular daily, 12 weeks, consumption of EpiCor syrup containing EpiCor and vitamin C in non-vaccinated children 1-6 years old on preventing episodes of the common cold and flu as well as on the severity of symptoms of the common cold and flu in case of their occurrence. Additionally, the study aims to assess the effect of EpiCor on the use of prescription drugs and changes of a selected biochemical marker. This is a double-blind, randomized, controlled multi-center clinical trial.

Full description

This is a double-blind, randomized, controlled multi-center clinical trial aiming to evaluate the effects of daily consumption of EpiCor with vitamin C, primarily on the incidence and, secondary, on the duration and severity of the common cold and influenza in children, compared to the effects of daily consumption of vitamin C alone. Healthy children aged 1-6 years old are included in the study after parents have provided informed consent for study participation. Children are divided in 3 age groups (1-2 year old, 3-4 years old, 5-6 years old) and randomized in one of the two groups (intervention or control) at a 1:1 ratio. Children eligible for participation are included in the study for 12 weeks. During this period, they visit the investigational center 3 times. During visit 1 (day 0) caregivers get familiarized with the purpose, course and procedures of the trial, provide written informed consent upon which investigator assesses child's suitability for participation and, for eligible children, a study participant number is provided and a randomization number is assigned; in addition, the investigator collects demographic information, data on vital signs, medical history, collects a sample for determination of salivary secretory immunoglobulin A (sIgA), provides caregivers with a Study Dairy and clear instructions regarding completion, consumption, storage and return of unused syrup, taking medication and other food supplements during the study, monitoring adverse events and measures to be taken in the event of serious adverse events, determines the daily dose of syrup to be taken based on child's age, supplies the caregiver with enough syrup and sets a date for next visit. Between visits, children take a prescribed dose of syrup once daily. Six weeks (visit 2) and 12 weeks (visit 3) after the first visit, children and caregivers visit the investigational center again. During these 2 visits, the investigator collects data on vital signs, reviews concomitant medication and the taking of other food supplements, collects sample for determination of salivary SIgA, reviews the Study Dairy, supplies the caregiver with new syrup and provides the same clear instructions as in visit 1. Caregivers are asked to complete the Study Dairy on daily basis and, each time a caregiver marks that a symptom is present, the Investigator receives a notification and reviews the symptoms and consequently confirms the episode of a common cold/flu. The Canadian Acute Respiratory Illness and Flu Scale (CARIFS) is used to assess the severity of symptoms of the common cold and flu in participating children and, in case of occurrence of cold/flu symptoms, caregivers are asked to complete the form twice a day for the first seven days, once on day 10 and once on day 14.
