Alanyl-glutamine for CDI

Study Purpose

This is a randomized, double-blind, placebo-controlled trial to determine the optimal dose and safety of oral alanyl-glutamine between 4, 24, and 44 g doses administered for 10 days with standard therapy among first time incident cases of uncomplicated C. difficile infection (CDI) in hospitalized persons aged 65 or older. Our hypothesis is that alanyl-glutamine supplementation will decrease recurrence and mortality from CDI and these outcomes will be associated with improvement of inflammatory markers and restoration of intestinal microbiota function.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT04305769
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
