About this study

Official title: A Double-blind, Randomized, Placebo Controlled, Multicenter Study of the Efficacy and Safety of BIO-K*+ CL-1285* in the Prevention of Antibiotic-associated Diarrhea in Adult Patients Exposed to Nosocomial Infection.

The purpose of this study is to evaluate the efficacy and safety of Bio-K + CL1285 versus placebo in the prevention of antibiotic-associated diarrhea in hospitalized adult patients.

Read the detailed description

Antibiotic-associated diarrhea (AAD) is one of the most frequent adverse events following antibiotherapy and is the leading cause of diarrhea in hospitalized patients. Ten to 25% of AAD are caused by the bacteria Clostridium difficile.

A recent unicenter study conducted at Maisonneuve-Rosemont hospital demonstrated the preventive role of Bio-K + CL1285 in antibiotic-associated diarrhea and Clostridium difficile-associated diarrhea. Its preventive role is thought to be mainly through restoration of the gastrointestinal flora affected in part by the antibiotherapy.

A wide body of literature reveals clinical use of probiotics, but few well controlled prospective studies conducted on large numbers of subjects have been performed.

In light of the positive preliminary results obtained in a limited number of patients with AAD and of the paucity of well controlled clinical trials, we now wish to undertake a randomized, double blind, multicentre study to evaluate the efficacy and safety of Bio-K + CL1285 prophylaxis vs. placebo in the prevention of antibiotic-associated diarrhea in hospitalized adult patients. As secondary objectives, we also intend to evaluate the incidence of Clostridium difficile-associated diarrhea and to demonstrate that BIO-K + CL1285 agent will not only improve the clinical outcomes but also reduce health care expenditures.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Incidence of Antibiotic-associated Diarrhea.

    Presence of at least one diarrhea episode within 24 hours.

    Measured: Up to 40 days

Secondary outcomes (3)
  1. Positive Results for Clostridium Difficile (C. Difficile) Toxin A or B in Antibiotic Associated Diarrhea Patients.

    Testing for CDAD was performed at the discretion of the treating physician and according to the protocol in place at the study centers. CDAD was defined as an episode of diarrhea and positive results for C. difficile Toxin A or B.

    Measured: Up to 40 days

  2. Health Outcome Evaluation Will Look at the Direct Medical Costs and Clinical Outcomes of Alternative Strategies in the Prevention of Antibiotic-associated Diarrhea in Hospitalized Adult Patients

    Measured: Up to 40 days

  3. Safety Profile of BIO-K+CL1285® Versus Placebo in Patients on Antibiotics

    Safety was assessed by the incidence of treatment-emerged adverse events, which were reported according to MedDRA 10.1

    Measured: Up to 40 days

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Lactobacillus acidophilus CL1285 and Lactobacillus casei in people with Diarrhea and Clostridium Infections, run by Bio-K Plus International Inc. at 8 sites in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 Aug 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Incidence of Antibiotic-associated Diarrhea. (time frame: Up to 40 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Aug 2014.
