Magnetic Resonance Imaging in Paediatric Constipation (MAGIC2) (MAGIC2)

August 30, 2023 updated by: Nottingham University Hospitals NHS Trust

A Multicentre Pragmatic Clinical Investigation to Assess the Efficacy of TransiCap MRI Marker Device in Magnetic Resonance Imaging in Paediatric Constipation (MAGIC2)

Constipation in children is a common problem. Managing these children is difficult, partly because they do not respond to laxatives and partly because their bowel problem cannot be defined. A "gut transit time" test can add information to help choose the best therapy but this is often not carried out because of the unsuitable radiation dose involved in the current methods such as X-ray. A new Magnetic Resonance Imaging (MRI) method to measure gut transit time using inert mini-capsules, the size of small pine nuts, has recently been developed and successfully trialled during a feasibility study.

This main multicentre study will trial the mini-capsules in 436 paediatric constipation patients.

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

A fully powered, multi-centre, open label, pragmatic Randomised Controlled Trial (RCT) to test the use of the TransiCap MRI visible capsules to inform treatment selection and whether this leads to a change in rate of "treatment success" at 12 months after diagnosis.

Two study arms will include 436 young patients that present at secondary or tertiary care with constipation.

All participants will receive the TransiCap MRI Visible Capsules and the MRI scans at presentation, but only the participants in the intervention arm will have the results of their scan shared with the standard care team immediately. The intervention arm will therefore receive treatment which is informed by the TransiCap MRI transit time test. The participants in the control arm will instead receive standard care not informed by theTransiCap MRI visible capsules.

The results of the scans will be shared with the standard care team after the patient's follow up of 12 months is complete. All participants will receive the TransiCap MRI visible capsules and the MRI scans

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

7 years to 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Inclusion Criteria:

Children aged 7 - 18 years old Able to give assent/consent or have a parent/carer able to give informed consent Willing to allow his or her General Practitioner and consultant, if appropriate, to be notified of participation in the clinical investigation.

Children diagnosed with clinical diagnosis of constipation

Exclusion Criteria:

The participant may not enter the clinical investigation if ANY of the following apply:

Female participants who are pregnant, lactating or planning pregnancy during the course of the clinical investigation. This will be self-reported.

Any history of gastrointestinal surgery that could affect gastrointestinal function, such as colectomy or small bowel resection.

  2. Antispasmodic Buscopan (hyoscine butylbromide, also known as scopolamine butylbromide) Participants who have participated in another research clinical investigation involving an investigational product in the past 12 weeks.

4 or more bowel movements in one week and no episodes of bowel incontinence in one week (if these are reported in the participant's medical notes. Absence of this information should not warrant exclusion)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Intervention
The intervention will consist of young patients with constipation presenting at secondary and tertiary care with intractable constipation. They will undergo the MRI gastrointestinal transit test (TransiCap). Their results will be shared with the patients after both MRI scans are preformed and results calculated. Their treatment selection will therefore be informed by the TransiCap results.
Device: TransiCap
The TransiCap device consists of small, completely inert mini-capsules that, once ingested, can be imaged inside the gastrointestinal tract using MRI, thereby creating a new MRI alternative to the radiopaque marker X-ray test to measure gut transit. The MRI mini- capsules are visualised in the gut using a single fat, water, in-phase and out-of-phase scan.
Experimental: Control
The control arm will consist of young patients with constipation presenting at secondary and tertiary care with intractable constipation. They will undergo the MRI gastrointestinal transit test (TransiCap). The patients will undergo 2 MRI scans but their results will be shared with the patients after 12 months has elapsed. They will receive standard care treatment not informed by the TransiCap results.
