Pediatric MSC-AFP Sub-study for Crohn's Fistula

March 11, 2024 updated by: Michael C. Stephens, Mayo Clinic

A Phase I Study of Autologous Mesenchymal Stromal Cell Coated Fistula Plug in Patients With Fistulizing Crohn's Disease: Pediatric Sub-study

The purpose of this study is to determine the safety of using an autologous mesenchymal stromal cell (MSC) coated fistula plug in people with fistulizing Crohn's disease. Autologous means these cells to coat the plug come from the patient.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The investigators propose to study the safety of autologous mesenchymal stromal cell transfer using a biomatrix (the Gore Bio-A Fistula Plug) in a Phase I study using a single dose of 20 million cells. 5 patients (age 12 to 17 years) with Crohn's perianal fistulas will be enrolled.

Subjects will undergo standard adjuvant therapy including drainage of infection and placement of a draining seton. Six weeks post placement of the draining seton, the seton will be replaced with the MSC loaded Gore fistula plug as per current clinical practice. The subjects will be subsequently followed for fistula response and closure for 24 months. This is an autologous product derived from the patient and used only for the same patient.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

12 years to 17 years (Child)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of participants with treatment-related adverse events (safety and toxicity)
Time Frame: 2 months to approximately at 24 months
Participants will have a health assessment and blood work done at each study visit to monitor for adverse events.
2 months to approximately at 24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of participants with response to the treatment regarding cessation of drainage from the treated fistula.
Time Frame: 2 months to approximately at 24 months
Participants will have a clinical assessment of fistula drainage at each study visit.
2 months to approximately at 24 months
Number of participants with radiographic response to the treatment regarding the treated fistula.
Time Frame: Week 2, Week 8, and Week 24
Participants will have an assessment of healing radiographically by magnetic resonance imaging (MRI) at Week 2 visit, Week 8, and Week 24.
Week 2, Week 8, and Week 24
