A Randomized, Double-Blind, Dose Response-Control, Crossover Study to Evaluate the Safety and Efficacy of Two Doses of EUR-1008 (APT-1008) in Chronic Pancreatitis (CP) Participants With Exocrine Pancreatic Insufficiency (EPI)

Study Overview
=================
Brief Summary
-----------------
The primary efficacy objective of this study is to evaluate the difference in coefficient of fat absorption (CFA) of participants treated with high dose EUR-1008 (APT-1008) versus low dose of EUR-1008 (APT-1008) in the treatment of signs and symptoms of malabsorption in participants with EPI associated with CP. This study is sponsored by Aptalis Pharma (formerly Eurand).

Detailed Description
-----------------
After screening, eligible participants will start the placebo baseline ambulatory phase (4 days). On day 5, they will be hospitalized for three to five days, to undergo a baseline 72-hour CFA determination under a controlled diet and using a stool marker to indicate the beginning and end of the controlled diet period, while they continue receiving placebo treatment. At the end of the placebo baseline phase, participants will be randomized to a high dose followed by a low dose or to a low dose followed by a high dose EUR-1008 (APT-1008) dose sequence and proceed to the first crossover (treatment) phase. Each crossover (treatment) phase will consist of a stabilization period for six days at home, followed by a hospitalization of three to five days to undergo a 72-hour CFA determination using a controlled diet and using a stool marker to indicate the beginning and end of the controlled diet period. Participants will immediately proceed from the first crossover (treatment) phase to the second without a washout period or return-to-baseline period in between phases. Participants will be stabilized at home for 6 days. Any residual lipase from the prior treatment phase is likely to be a negligible influence on the subsequent CFA determination because participants will be taking the new dose level (high or low) for six days before the beginning of sample collection for a new CFA. This interval is more than enough time for the CFA to be reflective of only the new dose.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percent Coefficient of Fat Absorption (CFA) of Participants Treated With High Dose EUR-1008 and Low Dose EUR-1008 | Percent CFA was calculated as ([fat intake - fat excretion]/fat intake)*100, determined in the stools collected during the 72-hour CFA determination period. Mean percent CFA was calculated for the 3 to 5 days of hospital treatment in first and second intervention periods. | 3 to 5 days of hospital treatment in first and second intervention periods | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Placebo Baseline in Percent Coefficient of Fat Absorption (CFA) in High Dose EUR-1008 and Low Dose EUR-1008 During Hospital Treatment | Percent CFA was calculated as ([fat intake - fat excretion]/fat intake)*100, determined in the stools collected during the 72-hour CFA determination period. Mean percent CFA was calculated for 3 to 5 days of hospital treatment in first and second intervention periods. | Baseline, 3 to 5 days of hospital treatment in first and second intervention periods | 
| Change From Placebo Baseline in Percent Coefficient of Nitrogen Absorption (CNA) During Hospital Treatment | Percent CNA was calculated as [(nitrogen intake - nitrogen excretion)/nitrogen intake]*100 , determined in the stools collected during the 72-hour CNA determination period. Nitrogen intake was calculated as protein intake/6.2. Nitrogen excretion was measured as total fecal nitrogen. Mean percent CNA was calculated for 3 to 5 days of hospital treatment in first and second intervention periods. | Baseline, 3 to 5 days of hospital treatment in first and second intervention periods | 
| Change From Placebo Baseline in Weight at End of Each Treatment Period | Mean change from baseline in weight was calculated for end of treatment (6 days home treatment and 3-5 days hospital treatment) in first and second intervention periods. | Baseline, end of treatment (6 days home treatment and 3-5 days hospital treatment in first and second intervention periods) | 
| Change From Placebo Baseline in Body Mass Index (BMI) at End of Treatment | BMI was calculated by weight divided by height squared and measured as kilogram per square meter (kg/m^2). Mean change from baseline in BMI was calculated for end of treatment (6 days home treatment and 3-5 days hospital treatment) in first and second intervention periods. | Baseline, end of treatment (6 days home treatment and 3-5 days hospital treatment in first and second intervention periods) |
