Clinical Trial Summary

This study assesses the efficacy and safety of Viokase® 16 for the correction of steatorrhea (malabsorption of dietary fats) in patients with a history of exocrine pancreatic insufficiency (EPI) due to chronic pancreatitis (CP) or pancreatectomy. This study is sponsored by Aptalis Pharma (formerly Axcan).

Description:

This study is a Phase III, multicenter, randomized, double-blind, parallel, placebo-controlled study, to assess the efficacy and safety of Viokase® 16 for the correction of steatorrhea in patients with EPI due to CP or pancreatectomy. The study will include the following phases: screening phase (up to 10 days), wash-out phase (6 to 7 days), randomization phase (up to 10 days), and treatment phase (6 to 7 days).

In screening phase, patients will undergo screening procedures prior to entry into the study.

In wash-out phase, stool collection will be performed to allow determination of the baseline CFA.

In randomization phase, patients who qualify for the Treatment Phase (that is, patients who have a CFA% below 80%) will be randomized in the study.

In the treatment phase, patients will be randomized in a 2:1 ratio (Viokase® 16 or Placebo). In treatment phase, stool collection period will be performed to allow determination of the CFA% that will serve to assess the efficacy of Viokase® 16 for the correction of steatorrhea. Follow-up procedures will be scheduled 7 to 10 days after discharge. Patients who do not show abnormal findings, adverse events or concomitant medications during the treatment phase will be assessed via follow-up telephone call. Patients who show abnormal findings (physical examination, vital signs, clinical laboratory tests, adverse events, concomitant medications) during the treatment phase will complete a follow-up visit.

Exclusion Criteria:

• Patients with a known hypersensitivity and/or contraindication to any of the study medications, to their excipients, components or to Federal Food, Drug, and Cosmetic (FD and C) Blue No. 2 dye marker

• Patients with acute pancreatitis or with an acute exacerbation of CP at screening or within the last 2 weeks before screening

• Patients with any active or recurrent malignant pancreatic tumor

• Patients with a history of significant bowel resection

• Patients with a dysmotility disorder

• Patients with insufficient body mass (body mass index less than 18)

• Patient not willing to be off therapeutic doses for at least 7 days prior to study entry and throughout the course of the study, medications or products that could interfere with fecal fat excretion

• Patients who do not limit alcohol intake to less than or equal to 1 drink per day during screening and randomization phases and patients who do not refrain from drinking during inpatient periods of the study

• Patients who have been treated with the following drugs within 7 days prior to screening: H2-receptor antagonists, gastrointestinal anticholinergics and antispasmodics

• Patients known to have a significant medical and/or mental disease that would compromise the patient's welfare or confound the study results

• Patients with a history of fibrosing colonopathy, cirrhosis of the liver, or portal hypertension

• Patients who have a condition known to increase fecal fat loss including celiac disease, biliary cancer, biliary stricture, cholelithiasis, Crohn's disease, pancreatic cancer, radiation enteritis, tropical sprue, whipple's disease, lactose intolerance, pseudomembranous colitis

• Female patients who are pregnant or breastfeeding

• Patients who have received an investigational drug within 30 days prior to entering the screening phase of the study

• Patients with aspartate aminotransferase (AST) or alanine aminotransferase (ALT) levels greater than 3 times the upper limit of normal values or elevated uric acid levels greater than 1.5 times the upper limit of normal values

• Patients with causes for EPI other than CP and partial/total pancreas resection, example, cystic fibrosis, primary sclerosing cholangitis, hemochromatosis, isolated enzyme deficiency, deficiency in activation of enzymes in the small intestine etc

• Patients with a history or clinical evidence of any relevant cardio- or cerebrovascular, renal, endocrine, neurologic, infectious, other gastrointestinal, hematological, oncological or psychiatric disease or emotional problems, which, in the opinion of the investigator, would pose a significant risk for the patient, invalidate the giving of informed consent or limit the ability of the patients to comply with study requirements or interfere otherwise with the conduct of the study and the same applies for immunocompromised patients and/or neutropenic patients

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percent Coefficient of Fat Absorption (CFA)	Percent CFA was calculated as ([fat intake - fat excretion]/fat intake)*100, determined in the stools which was collected from Day 1 to Day 4 or Day 5 during the inpatient period of treatment phase. Mean percent (%) CFA was calculated for Day 1 to Day 4 or Day 5 in inpatient period of treatment phase.	Day 1 up to Day 4 or Day 5 in inpatient period of treatment phase	No
Secondary	Mean Daily Number of Stools	Mean daily number of stools of each patient was calculated from frequency of stools by the patient per day. Mean daily number of stools during the collection period (Day 1 to Day 4 or Day 5 in inpatient period of treatment phase) for total patients was summarized.	Day 1 up to Day 4 or Day 5 in inpatient period of treatment phase	No
Secondary	Percentage of Stools Categorized as Per Consistency	Stool consistency was categorized as hard, formed/normal, soft and watery. Percentage of stools of a specific consistency for each patient was calculated as: (total number of stools of specific consistency during the completed days of the inpatient period/ total number of stools during the completed days of the inpatient period)*100. Mean percentage of stool categorized as per consistency for total patients was summarized.	Day 1 up to Day 4 or Day 5 in inpatient period of treatment phase	No
