Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
* Subjects should have a definitive diagnosis of colonic CD or small bowel and colonic CD based on clinical, radiological, endoscopic and pathological findings.
* Subjects should have a CDAI score <150 at week 0
* Patients receiving the following treatment are eligible:

5 aminosalicylates, if the dose remained constant for 4 weeks before the screening visit and had been used continuously for 8 weeks before screening and the patient has previously flared whilst on the medication; Azathioprine/6MP, if the dose remained constant for 8 weeks prior to the screening visit and had been used continuously for 12 weeks before screening and the patient has previously flared whilst on the medication. Proprietary probiotic preparations must be stopped at least two weeks prior to starting the trial preparation.
* Concomitant use of any other immunosuppressant eg. Methotrexate, tacrolimus, cyclosporine, mycophenolate mofetil, must be at a stable dose of 8 weeks continuous use for 12 weeks prior to screening and the patient has previously flared whilst on the medication.
* Subjects must demonstrate their willingness to participate in the study and comply with the proceedings by signing a written informed consent.
* Men and women =18 to < 75 years of age of any race and gender
* Subjects must be free of any clinically significant disease, other than Crohn's disease, that would interfere with the study's evaluations.
* Subjects should understand and be able to adhere to the dosing and visit schedules; and agree to record symptom severity scores, medication times, concomitant medications and adverse events accurately and consistently in a daily diary.

Key exclusion criteria
Patients should not be enrolled into the study if they meet any of the following criteria:

Summary
Brief summary
The primary objective of the study is to compare the efficacy of the probiotic VSL#3 versus placebo, in addition to standard maintenance drugs, in maintaining remission in Crohn's disease (CD).

The secondary objectives are:

* To determine the time till flare of CD patients on VSL#3 compared to placebo.
* To assess whether concurrent therapy with VSL#3 leads to an improvement in the quality of life (QOL).
* To assess whether concurrent therapy with VSL#3 reduces the severity of a flare if it occurs.
