About this study

Official title: An Open-Label Pilot Study of Fundamental Modification of the Gut Microbiota in the Treatment of Refractory Crohn's Disease

The purpose of this study is to determine the effect of a novel gut microbiota-targeted therapeutic regimen (bowel lavage and antibiotics with or without an antifungal) in the management of active Crohn's Disease (CD) or indeterminate colitis (IBDU) that is refractory to conventional, immunosuppressive therapy. In addition, the study will determine the effect of PEG lavage alone on fecal calprotectin and gut microbiota in patients who are undergoing a PEG lavage for clinical care.

Read the detailed description

Investigators will evaluate the efficacy of a novel treatment regimen, employing non-immunosuppressive medications, in the management of refractory CD or IBDU. Refractory patients include those patients who have experienced loss of responsiveness (LOR) or primary nonresponse to an immunomodulator or a biologic. Investigators will treat participants with a combination of gut microbiota-targeted therapies to restore a healthy gut microbiome composition. Investigators believe that this strategy will both treat the gut inflammation associated with inflammatory bowel disease (IBD) as well as salvage response to immune suppressive therapies.

Investigators will also evaluate the effect of PEG lavage alone on fecal calprotectin and gut microbiota. Participants in this arm, will be undergoing a PEG lavage in preparation for a endoscopy for clinical care. They will be asked to provide stool samples, prior to and after their PEG lavage. Participants will not be receiving any investigational treatments.

What is being measured

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

  1. Change in FCP in Group 2 Participants

    Change in fecal calprotectin between stool samples collected at baseline and day 12 after procedure in Group 2 participants.

    Measured: change from baseline to day 12

  2. Change in Disease Activity by Pediatric Crohn's Disease Activity Index

    The primary endpoint will be the change in disease activity, as measured by Pediatric Crohn's Disease Activity Index (PCDAI) score, between the enrollment visit and Day 15. All participants who withdraw for any reason prior to day 15 will be considered treatment failures. The Pediatric Crohn's Disease Activity Index is a clinical score which takes into account general well being, degree of abdominal pain, number of liquid stools per day, abdominal physical examination, and Crohn's disease complications.

    Measured: Baseline, Day 15

  3. Change in Disease Activity by Fecal Calprotectin (FCP)

    The second primary outcome measure will be the change in disease activity, as measured by fecal calprotectin, between the enrollment visit and day 15. The fecal calprotectin is a stool test which measures intestinal inflammation.

    Measured: Baseline, Day 15

Secondary outcomes (2)
  1. Change in C-reactive Protein (CRP)

    A secondary outcome measure will be the change in C-reactive protein between the enrollment visit and day 15. The C-reactive protein is a blood test which measures systemic inflammation.

    Measured: Baseline, Day 15

  2. Safety and Tolerability of the Treatment Regimen Based on Medication Side Effects and/or Adverse Events

    Measured: 105 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Vancomycin, Neomycin and Ciprofloxacin in people with Crohn Disease, run by Children's Hospital of Philadelphia at 1 site in United States.

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 12 inclusion and 14 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 9 Feb 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 United States. 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?

Yes. Results are posted in the registry (first posted 9 Feb 2022). 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?

Change in FCP in Group 2 Participants (time frame: change from baseline to day 12). The study lists 3 primary outcomes in all. 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 9 Feb 2022.
