|Official Title:||Efficacy and Safety of Ultrase® MT20 in Improving the Coefficient of Fat Absorption (CFA%) in Children With Cystic Fibrosis (CF) and Pancreatic Insufficiency (PI)|
- Percent Coefficient of Fat Absorption (CFA) [ Time Frame: Day 3 to Day 5 or Day 6 during washout phase and treatment phase ]Percent CFA was calculated as ([fat intake - fat excretion]/fat intake)*100, determined by the stools collected during the 72-hour period in either washout phase or treatment phase. Mean percent CFA was calculated for Day 3 to Day 5 or Day 6 of the respective phase.
- Percent Coefficient of Nitrogen Absorption (CNA) [ Time Frame: Day 3 to Day 5 or Day 6 during washout phase and treatment phase ]Percent CNA was calculated as [(nitrogen intake-nitrogen excretion)/nitrogen intake]*100, determined by the stools collected during the 72- hour period in either washout phase or treatment phase. Nitrogen intake was calculated as protein intake/6.25. Nitrogen excretion was measured as total fecal nitrogen. Mean percent CNA was calculated for Day 3 to Day 5 or Day 6 of the respective phase.

|Experimental: Ultrase® MT20||
Drug: Ultrase® MT20
Ultrase® MT20 capsules will be administered orally with each meal during Day 1 to 15 in screening phase at a dose based on investigator's discretion. During Day 12 to 15, participants will receive high-fat diet and Ultrase® MT20 dose will be adjusted depending on symptoms of steatorrhea. This will be followed by a washout phase of 6 to 7 days, in which participants will receive only high-fat diet; then stabilized dose of Ultrase® MT20 capsule (as identified during screening phase) will be administered orally for 7 to 11 days during treatment phase. The stabilized dose should not to exceed 2500 lipase units per kilogram body weight per meal (lipase units/kg/meal).
This is a Phase III, multicenter, open-label study, which will quantify the improvement of nutrient absorption when participants are receiving Ultrase® MT20. The improvement will be demonstrated by comparing the CFA percent (%) and CNA% obtained during a washout of enzyme with the CFA% and CNA% obtained during a period of treatment with Ultrase® MT20. The study is also designed to obtain safety data in CF children suffering also from PI taking Ultrase® MT20. The total duration for the participation of children in this study will be approximately up to 38 days and will include 3 phases: screening phase, the washout phase and treatment phase.
Screening phase: this phase will last 15 days and all participants will take Ultrase® MT20 as per investigator's discretion during this period. During the last 4 days, participants will be stabilized on a high fat diet and with Ultrase® MT20. The individual 'stabilized dose' of Ultrase® MT20 capsules will be determined for each participant based on the average number of capsules of Ultrase® MT20 taken during last 4 days.
Washout phase: this phase will last 6 to 7 days. The participants will continue the high-fat diet but will refrain from taking Ultrase® MT20 or any other enzymes. A 72-hour stool collection will be performed and all food consumed by the participants will be recorded to assess the CFA% and CNA%.
Treatment phase: this phase will last 7 to 11 days. The participants will continue the high-fat diet and will take the 'stabilized dose' of Ultrase® MT20 established during screening. Another 72-hour stool collection will be performed and all food consumed by the participants will be recorded to assess the CFA% and CNA%.
