Bioavailability of Pancreatic Enzymes in the Human Upper Intestine (Duodenum and Jejunum)

Overview

The overall purpose of this research is to demonstrate (or measure) the intestinal availability of lipase, amylase, and protease (enzymes the body has a shortage of) from PANCRECARB® when administered with a meal.

Detailed Description

Eligible patients for this placebo-controlled study had confirmed exocrine pancreatic insufficiency with a stool pancreatic elastase of <75 mcg/g. Patients who satisfied all inclusion criteria are prepared for endoscopic placement of three Liguory nasal biliary aspiration catheters: one 8.5 fr. catheter in the distal duodenum for aspiration, one 7.0 fr. catheter in the first portion of the duodenum for infusion of a PEG marker (4 mL/min) and one 7.0 fr. in the stomach for aspiration. Baseline samples are obtained from the gastric and distal duodenal ports and placed on ice. Subjects are then asked to swallow 5 capsules of a placebo (Phase I) or the test drug (PANCRECARB® (pancrelipase) – Phase II) with a standardized Lundh meal. Gastric samples are collected once an hour and duodenal samples are collected every 15 minutes for each phase (4 hours each). All collected samples were tested for the following parameters to demonstrate bioavailability of enzymes originating from PANCRECARB® (pancrelipase): lipase, amylase and protease activities, pH (bicarbonate), and protein fingerprinting by SDS-PAGE analysis.

Interventions

  • Drug: pancrelipase
    • The test drug (PANCRECARB® [pancrelipase] – Phase II) with a standardized Lundh meal. Gastric samples are collect once an hour and duodenal samples are collected every 15 minutes for each phase (4 hours each).
  • Drug: placebo
    • 5 capsules of a placebo drug (Phase I) with a standardized Lundh meal. Gastric samples are collect once an hour and duodenal samples are collected every 15 minutes for each phase (4 hours each).

Arms, Groups and Cohorts

  • Placebo Comparator: Phase I
    • All subject participate in Phase I
  • Active Comparator: Phase II
    • All subject participate in Phase II

Clinical Trial Outcome Measures

Primary Measures

  • Evidence of the bioavailability of lipase, amylase and protease in the upper intestine from exogenously administered PANCRECARB® (pancrelipase), when taken with a Lundh test meal.
    • Time Frame: 4 hours post administration of PANCRECARB® and or Placebo
