About this study

Official title: Efficacy of Secretin Assisted Dynamic MRCP in the Diagnosis and Follow up of Auto Immune Pancreatitis(AIP)

BACKGROUND:

Auto immune pancreatitis (AIP), a benign pancreatic disease has certain morphological forms which mimics pancreatic malignancy in radiological appearance. There is no singe diagnostic test which can accurately differentiate these two conditions. In the past, AIP accounted for up to 27% of Whipple resections performed for suspected adenocarcinoma.

AIMS:

To evaluate the efficacy of Secretin assisted Magnetic resonance cholangio pancreatography (MRCP) in differentiating AIP and pancreatic malignancy.

METHODS:

100 patients suspected with AIP will be consented to participate in the study to undergo secretin MRCP in addition to their other standard investigations. Patients will be categorized as those with AIP and with pancreatic malignancy based on these results and will be followed. Follow up will eventually give the true diagnosis when patients with pancreatic malignancy undergo pancreatic surgery and their pancreatic tissue is examined by histopathologist. AIP patients will undergo steroid trial which will give the true diagnosis. The preliminary diagnosis results based on standard investigations with and without inclusion of secretin MRCP will be compared to the true diagnosis.

Read the detailed description

A total of 100 patients with suspicion of Auto Immune Pancreatitis will be identified from the multidisciplinary pancreatic cancer clinic at Johns Hopkins and from the Pancreatitis clinic of the Division of Gastroenterology, Johns Hopkins Hospital.

After written, informed consent is obtained; preliminary screening will be done which includes medical history and physical examination including weight and vital signs. Serum immunoglobulin G4 (IgG4) levels will also be evaluated. If the patient meets exclusion/inclusion criteria, screening eligibility and signs informed consent, they will be included in the study.

Study investigators and/or their delegate will complete the patient demographic form, medical history form, baseline physical examination, baseline laboratory evaluation and concomitant medication evaluation as per the protocol. Any other investigational procedure such as endoscopic ultrasonography - fine-needle aspiration (EUS - FNA) or esophagogastroduodenoscopy (EGD) with papillary biopsy for IgG4 which assists in the differentiation between AIP and Pancreatic malignancy may be performed based on the treating physician's discretion.

Involvement of other organs by AIP and Pancreatic malignancy will be obtained based on the medical history, examination and imaging findings. The patients will be subjected to MRI and MRCP with the MRCP performed in two stages namely before injection of secretin and after intravenous injection of 0.4mcg/Kg of synthetic human secretin (CHIROSTIM, Human Secretin, CHIRHOCLIN Inc., Burtonsville, MD). All the subjects will be given 3 cups (approximately 500-600cc) of pineapple juice 5-10 minutes before the imaging procedure. Pineapple juice will act as a negative oral contrast which nulls the signal in stomach and duodenum, thereby suppressing gastrointestinal overlap over pancreas. MR Examination will be performed using 3.0 T magnet and it will include non contrast enhanced scanning followed by gadolinium enhanced scanning, performed during the arterial dominant, venous dominant and late phases. The secretin MRCP is performed through serial breath-hold T2-weighted sequences run during the first 8-12 min after the intravenous administration of secretin.

Based on the result from the above investigations, the patients will be categorized as those suspected with AIP and those suspected with Pancreatic malignancy. Patients with suspected malignancy will eventually undergo surgical resection of pancreas under their treating physician and the pancreatic tissue examination will provide the true diagnosis. Patients with suspected AIP will undergo a steroid trial for at least 3 months, at the end of which a repeat MRI, secretin MRCP will be performed and the diagnosis will be confirmed based on the response to steroid therapy.

What is being measured

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

  1. Evaluating the additive benefit of Secretin MRCP in differentiating focal AIP and Pancreatic malignancy

    Patients with suspected auto-immune pancreatitis (AIP)will undergo secretin assisted MRCP. The MRCP will be evaluated for post secretin changes in pancreatic dimensions, duodenal filling, pre and post contrast parenchymal signal intensities, ADC values, changes in pancreatic duct strictures due to secretin, extra pancreatic lesions.

    Measured: Participants will be followed during the interval between initial S MRCP and a repeat S MRCP after steroid treatment or a pancreatic surgery; an expected 4 weeks

Secondary outcomes (1)
  1. Efficacy of Secretin MRCP in monitoring therapeutic improvement in AIP patients on steroid trial

    The patients with suspected AIP based on secretin MRCP will undergo a steroid trial. The initial and follow up MRCP findings will be compared for changes in pancreatic parenchyma after injecting secretin, T1 signal intensities, ADC values, changes in pancreatic duct strictures,extra pancreatic lesions and duodenal filling.

    Measured: Participants will be followed up from initial S MRCP till resolution of pathology or till end of S MRCP follow-up studies; an expected 8 weeks

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 2 inclusion and 3 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: withdrawn, as of the sponsor's last update on 10 Jan 2019. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Evaluating the additive benefit of Secretin MRCP in differentiating focal AIP and Pancreatic malignancy (time frame: Participants will be followed during the interval between initial S MRCP and a repeat S MRCP after steroid treatment or a pancreatic surgery; an expected 4 weeks). 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 NCT01845467, which also lists 3 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 10 Jan 2019.
