Efficacy and Safety of BB-12 Supplemented Strawberry Yogurt For Healthy Children on Antibiotics (PLAY ON)

February 18, 2025 updated by: Daniel Merenstein, Georgetown University
Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. One of the most common indications for probiotic treatment is the prevention of antibiotic-associated diarrhea (AAD). Unfortunately, many probiotic products used for AAD are not supported by rigorous independent research, and often results in non-evidence-based usage. The overarching objective is to move research forward for the most well-studied Bifidobacterium strain. The primary aim is to test the efficacy of high dose, BB-12-supplemented yogurt in preventing AAD, compared to yogurt without BB-12, in children receiving antibiotics. Other aims are to further assess the safety of yogurt supplemented with BB-12, and to carry out longitudinal community structure and gene expression analysis of fecal microbiota to evaluate the impact of high dose BB-12 in a pediatric population receiving antibiotics. The microbiota includes hundreds of species, and its disruption is hypothesized to be an important factor in the development of AAD.

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
Number of Participants Experiencing Diarrhea
Time Frame: 14 days
Diarrhea is clinically defined as three or more loose stools per day for two consecutive days. This will be a dichotomous (yes or no) outcome of diarrhea.
14 days
Adverse Events
Time Frame: Days 0-180
Number of reported adverse events over the duration of the study
Days 0-180

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
Pediatric Quality-of-life Score
Time Frame: 7 days

The PedsQL Measurement Measurement Model for the Pediatric Quality-of-Life Inventory.

Based on the PedsQL form filled out by participants, the scores were translated using the PedsQL form guidelines: 0=100, 1=75, 2=50,3=25,4=0. The raw scores of participants were averaged after translation. The lowest possible score is 0 and the highest possible score is 100. A higher score indicates a healthier lifestyle.
