Summary
The purpose of this research study is to learn about the activity of oral Pancrecarb® (a
pancreatic enzyme preparation which contains proteins that help to digest food),
administered by mouth as a capsule filled with specially coated granules in patients taking
exogenous pancreatic enzyme therapy. Specific enzymes activities will be determined from
samples of stomach and intestinal fluids after a standard liquid meal.
Clinical Details
Official title: Intraduodenal Aspiration Study to Assess the Bioavailability of Oral Pancrecarb® Compared to Placebo Control in Patients With Pancreatic Insufficiency
Study design: Supportive Care, Open Label, Placebo Control, Single Group Assignment, Bio-availability Study
Primary outcome: Peak levels of three enzymes - lipase, amylase, and protease - each measured in U/ml will be outcomes
Detailed description:
Purpose:
The purpose of this study is to assess the bioavailability of oral Pancrecarb® (exogenous
pancreatic enzyme administered orally as a capsule filled with enteric coated granules)
compared to placebo control in patients with pancreatic insufficiency. Lipase, amylase and
protease activities will be determined from stomach and duodenal aspirates after standard
meal stimulation.
Participants:
Patients with pancreatic insufficiency will be recruited as the study population.
Procedures (methods):
Eligible subjects will undergo an initial screening phase and will provide a stool sample to
confirm pancreatic exocrine insufficiency based on a spot fecal elastase-1 of < 75 mcg/g
stool. Within one month after the screening phase, subjects meeting inclusion criteria will
be scheduled to arrive in the GCRC by 7pm. If the subject is a female of child bearing age,
a serum pregnancy test will be checked. At 6am the subject will be escorted to fluoroscopy
for placement of an oro-enteric tube. Once the tip of the tube has been positioned in the
duodenum, the subject will be escorted back to the GCRC. Prior to administration of the
capsules and liquid diet, baseline gastric and duodenal secretions will be aspirated via the
oro-enteric tube by the investigators. Subjects will then receive 5 capsules of placebo with
a standard liquid Lundh diet of 360 mL over a 10 minute period, administered to simulate a
fed state. Then duodenal and gastric secretions will be aspirated from the tube over a
3-hour period. At the end of the 3 hours, the subject will be allowed to rest for 60
minutes. The second phase will consist of 5 capsules of Pancrecarb®, again with a standard
liquid Lundh diet , and another 3-hour aspiration phase. After the second 3-hour aspiration
period, the balloon will be deflated and the tube will be removed. Subjects will be
observed for 30 minutes and then discharged.

Criteria:
Inclusion Criteria:
