About this study

Official title: Study to Assess Pancreatic Blood Flow at Rest and During Stimulation Using Magnetic Resonance Imaging (fMRI) in Patients With Chronic Pancreatitis

The purpose of this study is to assess pancreatic perfusion in patients with chronic pancreatitis at rest and after secretin stimulation and compare this to published data on pancreatic perfusion in normal subjects.

Read the detailed description

Pancreatic blood flow or perfusion is difficult to quantify due to the complex vascular supply to the organ and its retroperitoneal location, adjacent to the abdominal aorta. The pancreas is supplied by the superior gastroduodenal artery from the celiac plexus, branches from the hepatic and splenic arteries, which originate from the celiac plexus, and the inferior gastroduodenal artery, which originates from the superior mesenteric artery. Identifying changes in flow in all these vessels with good spatial and temporal resolution is challenging but important in understanding many of the chronic conditions of the pancreas.

Chronic pancreatitis (CP) is an inflammatory condition of the pancreas leading to irreversible damage to the tissue. It is increasing in incidence in all nations, and is related to rising alcohol consumption and improved diagnostic techniques. In Europe the incidence is approximately 6-7/100,000 population. 73-91% of patients affected are male with an average age of 49-60yrs. Patients affected by CP have a high morbidity, such as diabetes and chronic abdominal and/or post-prandial pain in 80-90%, which required frequent hospital admission, control-drug prescriptions and intervention by specialist hospital services. However the mechanisms of chronic and post-prandial pain for CP patients are not well understood, but tissue ischaemia, inflammation and neurological changes have been proposed. These mechanisms may be inter-related with pancreatic inflammation and neurochemical changes, such as an increase substance P, which can produce vasoconstriction, reducing pancreatic perfusion and worsening ischaemia of intra-pancreatic nerves(3). A greater understanding of the ischaemic and inflammatory mechanisms behind the pain in CP, would greatly enhance the development of treatment for this and other debilitating conditions.

There are a few studies of pancreatic tissue perfusion in humans, those studies which have assessed perfusion have used invasive techniques such as endoscopic or laparoscopic measurement and hydrogen gas clearance methods. Although these methods have demonstrated decreased resting blood flow and little response to secretin stimulation in CP patients compared to healthy controls, the techniques are highly invasive, time consuming and expensive and can cause the participant significant morbidity. This has led to several non-invasive techniques including infusion of oxygen-15 water and positron emission tomography (PET), contrast-material-enhanced trans-abdominal ultrasound (US) or contrast-enhanced dynamic computer tomography (CT). However these techniques involve infusion of an exogenous marker to detect the change in flow rate and often require a radiation exposure or are operator dependant and give poor spatial or temporal resolution, limiting the usefulness of the studies.

MRI is an attractive alternative for the assessment of pancreatic perfusion, providing good spatial and temporal resolution with no radiation exposure. Two methods can be used, Contrast-Enhanced (CE) MRI or Arterial Spin Labelling (ASL) techniques. ASL provides a tool for quantitative assessment of tissue perfusion without the need for contrast administration.

Contrast-enhanced MRI using gadodiamide has been used to explore the changes in pancreatic perfusion with secretin stimulation. This study in 10 healthy volunteers demonstrated that at rest there was a higher blood flow within the body and the tail of the pancreas, compared to the head. With secretin stimulation there was a significant increased perfusion in all regions of the pancreas. ASL techniques, do not require exogenous contrast agents, only two previous studies have measured pancreatic perfusion with ASL, one exploring pancreatic exocrine functions in type 1 diabetics. A recent study at the Nottingham Digestive Diseases Centre on pancreatic perfusion measurement using ASL at baseline and after intravenous secretin stimulation has standardised the MRI technique of measuring pancreatic perfusion.

There are no studies using MRI ASL to measure pancreatic perfusion in patients with chronic pancreatitis after secretin stimulation. This pilot study aims to test the feasibility of using MRI ASL to measure pancreatic perfusion in patients with chronic pancreatitis with a view to perfecting the technique. This will allow future studies comparing pancreatic perfusion in healthy adult controls to patients with chronic pancreatitis thus improving the investigators understanding of the pathophysiology of pain in patients with chronic pancreatitis.

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 1 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 18 Feb 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 Kingdom. 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact John Simpson (j.simpson@nottingham.ac.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Blood flow to pancreas as measured by arterial spin labelling MRI (time frame: 1.5 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02458118, which also lists 12 linked publications.

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 18 Feb 2016.
