Effect of Probiotic Formula on Reducing the Risk for Antibiotic-associated Diarrhoea

January 21, 2016 updated by: Danisco
Antibiotic treatment disturbs the balance of the intestinal microbiota and predisposes to antibiotic associated diarrhea. Previous studies have shown that the risk of developing diarrhea during a course of antibiotics may be reduced by simultaneous consumption of probiotics. The aim of the present study is to assess the effect of a probiotic formula containing four strains on reducing the risk of antibiotic associated diarrhea.

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

The aim of the study is to assess the effect of a probiotic formula on reducing the risk of antibiotic-associated diarrhea (AAD). The study will be conducted as a two-arm, parallel groups, placebo-controlled, double-blind, randomized clinical trial, stratified by age, gender and number of days on antibiotics. The duration of patient participation in the study will be up to 7 weeks (up to 3 weeks supplementation, 4 weeks follow-up). The overall duration of the study is expected to be approximately 8 months. Adult males and females that are prescribed antibiotic therapy for minimum of 3 and a maximum of 14 days will be included in the study. The incidence of AAD will be evaluated as the primary end-point. The stool from patients presenting diarrhea will be tested for the presence of Clostridium difficile and if negative for C. difficile, also for the presence of other common pathogens causing diarrhea. The overall microbiota will be analyzed from fecal samples taken regularly during each phase of the study.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study
