About this study

The purpose of this study is to understand the immune response activated in the human gastrointestinal tract by Trichuris Suis Ova (TSO) in patients with ulcerative colitis.

Read the detailed description

The concept of helminthic therapy (using worms to treat diseases) is supported by experiments in mouse models as well as several clinical studies. TSO, which are purified eggs from the porcine whipworm Trichuris suis, are being investigated in clinical trials as a potential therapeutic agent for the treatment of active Crohn's disease, relapsing multiple sclerosis, peanut and tree nut allergy, and adults with autistic disorders.

The goal of this study is to understand the immune mechanisms activated in the human gastrointestinal tract by treatment with TSO, which may lead to improvements in the symptoms of ulcerative colitis (UC). TSO have been shown to have a clinical benefit on a subset of patients with UC in a previous randomized placebo-controlled trial (Summers et al. 2005). However, the mechanisms of action of TSO on the intestinal mucosa remain unclear.

We propose an exploratory 24-week mechanistic randomized double-blind placebo-controlled crossover study of TSO in patients with established and active UC to better characterize similarities and differences in the immune mechanisms of the intestinal mucosa in response to TSO. We hypothesize that treatment with TSO will lead to an anti-inflammatory immune response in some individuals with UC through an increase in intestinal mucus production and modulation of Th1, Th2, Th17, and T-regulatory effector lymphocyte populations.

Questions about this trial

What is this clinical trial studying?

A study testing Trichuris suis ova in people with Ulcerative Colitis, run by NYU Langone Health 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 8 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 1 Jul 2016. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Jun 2016). 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 From Baseline of Mucus Production at 12 Weeks and 24 Weeks as Assessed by Histopathology (time frame: Baseline, 12 weeks, 24 weeks). The study lists 4 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 1 Jul 2016.
