The Effect of Probiotics on Symptoms of Infantile Colic

Phase 2

Withdrawn

• Conditions: Colic
• Interventions: Dietary Supplement: Probiotic Formulation; Dietary Supplement: Placebo

• Registration Number: NCT05198700
• Lead Sponsor: Lallemand Health Solutions

Brief Summary

The aim of this study is to evaluate the effects of a probiotic formulation on the daily crying patterns of infants. It is hypothesized that participants given the probiotic formulation will show a significant reduction in daily crying duration compared to participants receiving the placebo.

Detailed Description

Participants diagnosed with symptoms of infantile colic will be recruited to participate in this randomized, double-blind, placebo-controlled, two-arm parallel study. Eligible participants will be enrolled in this study for 6 weeks, and will undergo a 1-week run-in baseline period followed by a 4-week interventional period, then a 1-week follow-up period.

The study will consist of 7 visits (V0 to V6): 4 in-person visits that alternate with 3 phone calls.

Arm && Interventions

Group	Intervention	Description
Experimental Group	Probiotic Formulation	Participants in this group will be randomized to receive the probiotic formulation for 4 weeks.
Control Group	Placebo	Participants in this group will be randomized to receive the placebo for 4 weeks.

Primary Outcome Measures

Name	Time	Method
Symptoms of infantile colic	5 weeks	Comparison of the difference in the proportion of infants with reductions in mean daily crying duration by over 50 percent from baseline between the probiotic and placebo groups, as assessed by the baby's Daily Diary.

Secondary Outcome Measures

Name	Time	Method
Symptoms of infantile colic: Parental perception	5 weeks	Comparison of the difference in the perceived evolution of colic symptoms by parents of participants in the probiotic and placebo groups, as assessed by questions about the evolution of colic symptoms at visits 2 and 4.
Change in the mother's quality of life	5 weeks	Comparison of the changes in the overall score of the SF-36 from baseline (0 to 100; a higher score corresponds to a better quality of life), between mothers of participants in the probiotic and placebo groups.
Symptoms of infantile colic: Time to a 25 and 50 percent reduction in cry/fuss time	5 weeks	Comparison of the difference in time to reach a 25 percent and 50 percent improvement in cry/fuss time from baseline between the probiotic and placebo groups, as assessed by the baby's Daily Diary.
Fecal strain recovery of the probiotic	5 weeks	Presence of the probiotic strain in participants in the probiotic group, as determined by qPCR analysis of stool samples collected at baseline and at week 4.
Bowel movement frequency	5 weeks	Comparison of the changes in bowel movement frequency and consistency from baseline between the probiotic and placebo groups, as assessed by the Amsterdam Infant Stool Scale.
Fecal microbiome composition	5 weeks	Comparison of the differences in the composition of fecal microbiota and mycobiota between the probiotic and placebo groups, as determined by 16S sequencing of stool samples collected at baseline and at week 4.
Symptoms of infantile colic: Daily crying duration	5 weeks	Comparison of the average change from baseline in the mean daily crying duration between the probiotic and placebo groups, as assessed by the baby's Daily Diary.
Symptoms of infantile colic: Number of crying episodes	5 weeks	Comparison of the change in the number of crying episodes from baseline between the probiotic and placebo groups, as assessed by the baby's Daily Diary.
Symptoms of infantile colic: Sleep duration	5 weeks	Comparison of the difference in sleep duration from baseline between the probiotic and placebo groups, as assessed by the baby's Daily Diary.
