MAP-1: Markers in Acute Pancreatitis-1
Study Details
Study Description
Brief Summary
Prospective, multi-national, multi-centre observational diagnostic study of novel microRNA and protein biomarkers in peripheral blood and/or urine to detect and predict the severity of drug-associated acute pancreatitis (AP), with comparison of the same biomarkers in patients with acute pancreatitis from other causes, chronic pancreatitis, pancreatic cancer, diabetes mellitus and healthy volunteers.

Detailed Description
The MAP-1 study is designed to validate microRNA and/or pancreatic digestive enzyme biomarkers for the detection and severity assessment of drug-associated AP, for application to the assessment of adverse reactions to drugs in development or drugs already developed for other indications. The study will also assess the clinical utility of these biomarkers in AP from other causes, but is not designed to determine whether the biomarkers could be used in place of amylase and/or lipase in the standard clinical diagnosis of AP or to distinguish between the many differential diagnoses of AP. Selection is in progress of the microRNAs and pancreatic digestive enzyme biomarkers to be validated in this study, this selection being made from prospectively biobank samples obtained in a separate observational study that has separate ethical approval.
The pre-selected microRNAs and pancreatic digestive enzymes will be measured in the blood and urine of patients on admission to hospital with drug-associated acute pancreatitis (Group 1, 75 participants in receipt of one or more drugs on a defined list of drugs associated with acute pancreatitis) or other cause acute pancreatitis (Group 2, 250 participants not in receipt of any of the defined drugs). The same biomarkers will also be measured in blood and urine samples from contrast groups of patients with chronic pancreatitis (Group 3, 25 participants), pancreas cancer (Group 4, 25 participants), type I or II diabetes mellitus (Group 5, 25 participants) and healthy volunteers (Group 6, 100 participants). All participants will be at least 18 years old. MicroRNAs will be measured by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) and pancreatic enzymes by mass spectrometry.

Outcome Measures
Primary Outcome Measures
- MicroRNA panel [Day of admission]
Scale of change from normal (healthy volunteer values) of a panel of microRNAs measured in blood and urine samples from patients with mild, moderate or severe drug-associated AP during the first 24 hours of admission, confirming specificity by comparison with results from patients with other pancreatic diseases
Secondary Outcome Measures
- Pancreatic enzyme biomarker [Day of admission]
Scale of change from normal (healthy volunteer values) of a selected pancreatic enzyme biomarker in blood and/or urine taken from patients with mild, moderate or severe drug-associated AP during the first 24 hours of admission, confirming specificity by comparison with results from patients with other pancreatic diseases
- MicroRNA panel [Days 4 and 14 after admission]
Scale of change of circulating microRNAs measured in blood samples on Day 4 (+/- 1 day) and Day 14 (+/- 2 days) after admission to assess progression of AP
- Severity of AP [Within 90 days of admission]
Determination of AP severity will be made according to the Revised Atlanta Classification
- Patient reported outcome [Days 4 and 14]
Application of the PAtieNt-rePoRted OutcoMe scale in acute pancreatItis - an international proSpEctive cohort study (PAN-PROMISE) scale
- Progress of MAP-1 [Two years]
Progress of recruitment of patients into MAP-1
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Drug-associated AP: patients ≥18 years old undergoing drug treatment that has a defined risk of AP prior to and at the onset of AP and admitted to recruiting hospitals with a diagnosis of AP established by two of: (i) typical continuous upper abdominal pain (in this study for up to 2 days in duration prior to admission); (ii) amylase and/or lipase 3 or more times the upper limit of normal; (iii) characteristic findings on abdominal imaging (if undertaken urgently by computerised tomography scan (CT) or magnetic resonance imaging (MRI); and who undergo their first study blood sampling within 24 hours of admission to hospital.
-
Other cause AP: patients ≥18 years old not undergoing drug treatment that has a defined risk of AP and admitted to recruiting hospitals with a diagnosis of AP established by two of: (i) typical continuous upper abdominal pain (in this study for up to 2 days in duration prior to admission); (ii) amylase and/or lipase 3 or more times the upper limit of normal; (iii) characteristic findings on abdominal imaging (if undertaken urgently by CT or MRI) and undergo their first study blood sampling within 24 hours of hospital admission.
-
