Study summary

This study evaluates the effect of different complementary foods on the gastrointestinal microbiota of exclusively human milk fed infants.

Read the detailed description

The introduction of solid foods plays a role in shaping the microbial communities of the gastrointestinal microbiota. This randomized, controlled, single-blinded trial will evaluate the effect of four infant foods (oatmeal cereal, carrot puree, prune puree, beef and gravy puree) on the gastrointestinal microbiota of exclusively human milk fed infants that have not previously consumed solid foods and who are developmentally ready for the introduction of solid foods.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 17, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
