  Purpose

13C breath di-peptide tests are an effective non-invasive tool to detect pancreatic exocrine function in patients with Chronic Pancreatitis.


Condition Intervention Phase
Chronic Pancreatitis
Healthy Volunteers
Drug: benzoyl-L-tyrosyl-[1-13C]alanine (Bz-Tyr-Ala)
Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Crossover Assignment
Masking: Single Blind (Subject)
Primary Purpose: Diagnostic

Primary Outcome Measures:
  • To assess the pancreatic exocrine insufficiency using a 13C labeled di-peptide breath tests in patients with chronic pancreatitis(CP) and show correlation with secretin stimulated endoscopic Pancreatic Function Test (ePFT). [ Time Frame: 1 hour ] [ Designated as safety issue: Yes ]
    This breath test substrate is new and is hypothesized, based on preliminary studies, that it may be the answer to a much needed non-invasive pancreatic function test. At first stage, it will be compared to the current invasive gold standard: secretin induced ePFT.


Secondary Outcome Measures:
  • To assess the ability to differentiate between non patients with chronic pancreatitis and those without. [ Time Frame: 1 hour ] [ Designated as safety issue: Yes ]
    In order to establish the efficacy of this test, it is necessary to confirm that a difference is observed between healthy and non- healthy subjects


Enrollment: 33

Study Completion Date: March 2009
Primary Completion Date: February 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Di -petide breath tests and ePFT secretin induced
Di peptide breath tests will be performed on subjects with known chronic pancreatitis
Drug: benzoyl-L-tyrosyl-[1-13C]alanine (Bz-Tyr-Ala)
300 mg of powder form dissolved in one cup of tap water prior to breath test
Active Comparator: c13 di peptide breath tests
Healthy volunteers to compare breath tests results to subjects with chronic pancreatitis
Drug: benzoyl-L-tyrosyl-[1-13C]alanine (Bz-Tyr-Ala)
300 mg of 13 C di peptide in single dose powder form dissolved in one cup of tap water.

Detailed Description:

The aim of the study is to assess the pancreatic exocrine insufficiency using a 13C labeled di-peptide breath tests in patients with chronic pancreatitis(CP) and show correlation with secretin stimulated endoscopic Pancreatic Function Test (ePFT). Furthermore, a second purpose is to assess the ability to differentiate between non patients with chronic pancreatitis and those without. Approximately 30 subjects will be tested with both methods within two weeks of each other.
