About this study
Official title: A Single Center, Double-Blind, Randomized, Placebo-Controlled Study Evaluating the Efficacy of Bio-K+ Cl-1285® In the Nasal Decolonization of Methicillin Resistant Staphylococcus Aureus (MRSA) Carrier Patients
Trial Objectives:
Primary objective:
- To evaluate the efficacy of Bio-K+CL1285® in patients with Methicillin-Resistant S. aureus (MRSA) nasal colonization by comparing the MRSA decolonization following either Bio-K+CL1285® or placebo treatment.

Read the detailed description
Study Design:
Double-blind, randomized (1:1 randomization), placebo-controlled, single center Canadian study.
Patients will be randomly assigned to one of the two study products. A randomization schedule will be generated by the sponsor for each participating centre. This schedule will link patient identification numbers to one of the two study products allocated at random. The schedule will be prepared on a 1:1 randomization ratio.
The study products will be labelled with the patient identification number. Patients have to be randomized in the order in which they qualify from the screening phase for inclusion in the study.
Patients withdrawn from the study retain their patient number if already given. New patients must always be allotted a new identification number (PIN).
Study Duration:
The duration of patient participation in the study will be between 22 and 23 days. The overall duration of the study is expected to be approximately 10 months; with subject recruitment proposed to start in March 2009, the last follow-up visit is expected in May 2010. The actual overall study duration or subject recruitment period may vary.
Number of Sites (inside and outside of Canada):
One center in the province of Quebec will be involved in the study.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Bio-K+ CL1285 in people with MRSA Colonization, run by Bio-K Plus International Inc. at 1 site 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 13 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The record says: withdrawn, as of the sponsor's last update on 22 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
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?
Frequency of subjects with MRSA decolonization (time frame: 21 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 22 Jul 2022; AzTrials last refreshed its copy on 8 Nov 2026.
