NCT01274598

Brief Summary

This is a phase I, open label clinical trial to evaluate the safety of Lactobacillus rhamnosus GG (LGG) in elderly subjects. Lactobacilli are part of the normal flora of the intestine. LGG is one of several strains of Lactobacilli that is used as a probiotic or microorganism administered to confer "health benefits". Our research is focused on studying the possible therapeutic effects of LGG. The study hypotheses are:

  • LGG administered twice daily will be safe and well tolerated in elderly subjects
  • LGG will colonize the stool of elderly subjects and will modify the diversity and richness of the microbiota in their nasopharyngeal and stool specimens

Outcome Measures

Primary Outcomes (1)

  • Occurrence of adverse events that are possibly or probably related to administration of LGG

    Adverse events will be detected during study visits with standardized questionnaires, medical history, vital signs, physical examinations, laboratory tests and review of subject diaries as well as between study visits on telephone calls based on responses to adverse event questionnaires.

    through day 56

Secondary Outcomes (1)

  • Changes in the richness and bacterial diversity of the nasopharyngeal and gut microbiota and presence of LGG in stool specimens by routine culture

    through day 56

Study Arms (1)

Lactobacillus Rhamnosus GG, ATCC 53103 (LGG)

EXPERIMENTAL

Lactobacillus rhamnosus GG ATCC 53103 1 x 10\^10 twice a day for 28 days

Biological: Lactobacillus Rhamnosus GG, ATCC 53103 (LGG)

Interventions

1x10\^10 CFU by mouth twice daily for 28 days
