Safety and Efficacy Study of ULTRASE® MT20 in Participants With Cystic Fibrosis (CF) and Exocrine Pancreatic Insufficiency (PI)

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the safety and efficacy of Ultrase® MT20 compared to placebo for the correction of fat and protein malabsorption in participants with cystic fibrosis (CF) and exocrine pancreatic insufficiency (EPI). This study is sponsored by Aptalis Pharma (formerly Axcan).

Detailed Description
-----------------
This is a Phase III, multicenter, randomized, double-blind, two-period cross-over, placebo-controlled study designed to compare the efficacy and safety of Ultrase® MT20 to placebo in participants with CF and pancreatic insufficiency. The study consists of a screening period (up to 11 days) and two treatment periods (6-7 days). During screening period participants will be treated with open-label Ultrase® MT18 or MT20. Each treatment period will be preceded by a stabilization period (4 days) and the two treatment periods are separated by a break period (3-6 days). A safety follow-up visit will be performed 7-10 days after discharge from the last treatment period.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percent Coefficient of Fat Absorption (CFA) | Percent (%) CFA was calculated as ([fat intake - fat excretion]/fat intake)*100, determined by the stools collected during the 72-hour period which could extend to 96 hours during both intervention periods. Mean CFA percent was calculated for 72-hour/96-hour period during Day 3 to Day 7 in the first and second intervention periods. | Day 3 to Day 7 in first intervention period and second intervention period | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percent Coefficient of Nitrogen Absorption (CNA) | Percent (%) CNA was calculated as [(nitrogen intake-nitrogen excretion)/nitrogen intake]*100, determined by the stools collected during the 72-hour period which could extend to 96 hours during both intervention periods. Nitrogen intake was calculated as protein intake/6.25. Mean percent CNA was calculated for 72-hour/96-hour period during Day 3 to Day 7 in the first and second intervention periods. | Day 3 to Day 7 in first intervention period and second intervention period |
