A Study to Assess the Effect Probiotic Supplement on Immune Health in Teachers Prone to Upper Respiratory Tract Infection

June 19, 2025 updated by: Vedic Lifesciences Pvt. Ltd.

A Randomized, Double-blind, Placebo-controlled, Parallel Clinical Study to Assess the Effect of ProGenr8™ (Probiotic Supplement) on Immune Health in Teachers Prone to Upper Respiratory Tract Infection (URTI)

The present study is a randomized, placebo-controlled, double-blind, parallel-group clinical studydesigned to assess the effects of IP on immune health in teachers prone to URTI. Approximately 179individuals aged between 18 and 50 years will be screened. Considering a screen failure of 20%,approximately 144 individuals will be randomized in a ratio of 1:1 to receive either the active orplacebo. The study will have at least 100 completed participants i.e. 50 participants in each studyarm after accounting for a dropout/withdrawal rate of 30% at the end of the study. The interventionand follow-up duration for all the study participants will be 120 days.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
To Measure the effect of the 120 days' administration of IP on %population having one or more episodes of URTI during the study duration asassessed by Wisconsin Upper Respiratory Symptom Survey Questionnaire as compared to baseline and placebo.
Time Frame: Day 30,Day 90 & Day 120
The WURSS-21 includes nine items assessing the impact of the URTI episode on an individual's quality of life i.e., the ability to think clearly, sleep well, breathe easily, exercise, work inside and outside the home, accomplish daily activities, interact with others and live one's personal life. All the items will be scored on an 8-point Likert scale ranging from 0 which depicts "absent or no impairment" to 1 (very mild), 3 (mild) 5(moderate), and 7 (severe). Participants will be instructed to fill this questionnaire whenever they have a URTI episode on all days throughout the study. An average of all WURSS-21 QoL scores will be calculated for every episode and considered to analyze the change in QoL as compared to baseline and placebo.
Day 30,Day 90 & Day 120

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
To Measure the effect of IP in comparison to baseline and placebo on-Severity of the URTI episodes as assessed by Wisconsin Upper Respiratory Symptom Survey Questionnaire(WURSS-21)
Time Frame: From Date of Randomization upto 120 days
In WURSS-21 All the items will be scored on an 8-point Likert scale ranging from 0, which depicts "absent or no impairment", to 1 (very mild), 3 (mild), 5 (moderate), and 7 (severe).43 The global score of WURSS-21 (question no. 1-19) ranges from 0-133 per day. Higher scores represent higher severity
From Date of Randomization upto 120 days
To Measure the effect of IP in comparison to baseline and placebo on-Severity of the URTI episodes as assessed by Number of URTI episodes
Time Frame: From Date of Randomization upto 120 days
the number of URTI episodes (frequency) and proves to be beneficial in individuals suffering from frequent URTI episodes
From Date of Randomization upto 120 days
To Measure the effect of IP in comparison to baseline and placebo on -Body composition (Fat tissue, lean mass, fat free mass) as assessedby Dual Energy X-ray Absorptiometry -Gut microbiome analysis as assessed by Next Generation Sequencing
Time Frame: Day 0 and Day 120
Dual Energy X-ray Absorptiometry Scans can assess fat content and total body composition with a high degree of precision that is comparable to hydrostatic weighing The investigation of the gut microbiota in a culture-independent manner has been made possible by next-generation sequencing technology, which has provided insights into the intricate and little-understood interactions between the gut microbiome and its host
