Condition(s) targeted: Exocrine Pancreatic Insufficiency

Intervention: pancrelipase (Drug); placebo (Drug)

Phase: N/A

Status: Terminated

Sponsored by: Digestive Care, Inc.


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.

Clinical Details

Official title: 092206: Bioavailability of Pancreatic Enzymes in the Human Upper Intestine (Duodenum and Jejunum) From PANCRECARB® (Pancrelipase), Delayed Release Capsules, Buffered and Enteric-Coated Microspheres

Study design: Allocation: Non-Randomized, Endpoint Classification: Bio-availability Study, Intervention Model: Single Group Assignment, Masking: Open Label

Primary outcome: 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.

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.


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

pancreatic enzymes

- Current daily prescribed scheduled use of narcotics (patients requiring PRN use of

narcotics are not excluded)

- A medical condition which the investigator deems significant enough to interfere with

the ability of the subject to participate in the intubation study or interfering with assessment or enzyme bioavailability

- Stomach pH > 4

- Small bowel disease (i. e. celiac disease)
