A Study on Efficacy of Feeding N1115 Probiotic Supplement to Young Children (N1115Baby)

July 22, 2018 updated by: Shijiazhuang Junlebao Dairy Co., Ltd.

A Randomized, Double-blinded, Parallel, Placebo-controlled Study to Investigate the Efficacy of Lb Paracasei [Junlebao Lp. N1115] as a Probiotic to Enhance Gut Development in Young Children

The aim of the study is to examine the intervening effects of N1115 Probiotic Supplement (containing Junlebao Lp. N1115) on gut development in young children at the age of 6 month to 3 years by the way of a randomised, double-blinded, parallel, placebo-controlled clinical trial, and to explore the change of intestinal microbiota composition and healthy condition after intervention.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

N1115 Probiotic Supplement contains Lactobacillus paracasei N1115 [Junlebao Lp. N1115], a lactobacillus bacteria strain isolated from traditional homemade yogurt in North China. In recent studys feeding Junlebao Lp. N1115 to C57BL/6 mice, the data suggest that Lp. N1115 enhances intestinal development in neonatal mice, and may confer benefits on the growth at early stage of life.

This study is to investigate if a N1115 Probiotic Supplement product containing Lp. N1115 will improve intestinal health in young children. This randomised, double-blinded, placebo-controlled trial includes two treatment groups which respectively need to recruit 30 volunteers born by cesarean section and aged from 6 months to 3 years. The study group receives N1115 Probiotic Supplement, while the control group receives placebo. The trial lasts for 8 weeks and include four time points of data collection. The stool consistency of children will be recorded everyday, the saliva and stool samples will be collected and analysed.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

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.

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.

Time Frame: 8 weeks

Compare the defecation condition of child both in intervention group and placebo group by the way of recording the questionnaire each day.

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.
