Brief summary: This is a Phase III, multicenter, open-label study, that will evaluate the improvement of nutrient absorption when participants will receive Ultrase® MT20. This study is sponsored by Aptalis (formerly Axcan). This study is performed in children from 7 to 11 years old.

Detailed description: 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%.

Eligibility criteria: Inclusion Criteria:

* After a full explanation of the study, participants or their legally authorized representative must have signed the informed consent or assent form along with a parental form
* Participants must have a confirmed diagnosis of CF based on one or more clinical features consistent with the CF phenotype, and one of the following:

  * A genotype with two identifiable mutations consistent with CF
  * A sweat chloride test greater that 60 millimole per liter (mmol/L) by quantitative pilocarpine iontophoresis
* Participants must have PI as demonstrated by a fecal elastase-1 (FE-1) concentration less than 100 microgram per gram (mcg/g) of stools (ScheBo test) and requiring pancreatic enzyme supplementation
* Participants must be clinically stable according to the physician's judgment by:

  * Medical and medication history
  * Baseline physical examination including vital signs and laboratory analyses
* Participants must be 7 to 11 years of age
* Participants must have an adequate nutritional status based on body mass index (BMI) greater than or equal to fifth percentile
* Participants must be on an optimal clinical dose of pancreatic enzymes (Ultrase® MT12 , MT18 or MT20 or other pancreatic enzyme preparations) prior to entry in the study and must tolerate this medication in the opinion of the investigator
* Participants must be able to be able to swallow capsules and eat a high-fat diet calculated as 2 gram fat per kilogram (g fat/kg) of body weight per day
* Participants must be, in the opinion of the investigator, able and willing to complete the study
* Female participants should be premenarcheal. Otherwise, a female participant of childbearing potential (WOCBP) must not be pregnant and must have practiced an acceptable method of contraception for at least 1 month prior to the study entry

Exclusion Criteria:

* Participants with a known contraindication, sensitivity or hypersensitivity to Ultrase® MT20 or any porcine protein
* Participants with a known allergy to the food, drug and cosmetic (FD\&C) Blue No. 2 dye indicator (stool marker)
* Participants who are not willing to stop the prohibited medications or products at study entry and throughout the study
* Participants who use narcotics chronically and bowel stimulants and/or laxatives on a regular basis
* Participants with acute pancreatitis or acute exacerbation of chronic pancreatic disease
* Participants with an acute pulmonary infection
* Participants with a history of bowel resection
* Participants suffering from any dysmotility disorders
* Participants with chronic or severe abdominal pain
* Participants receiving enteral tube feeding and not willing to stop during the course of the study
* Participants with a significant medical disease that would compromise their welfare or confound the study results
* Participants with a history of or a current diagnosis of clinically significant portal hypertension
* Participants who have a condition known to increase fecal fat loss including celiac's disease, biliary cancer, biliary stricture, cholelithiasis, Crohn's disease, ulcerative colitis, pancreas cancer, radiation enteritis, tropical sprue, Whipple's disease, lactose intolerance, pseudomembranous colitis
* Participants with a current diagnosis or a history of complete distal intestinal obstruction syndrome (DIOS) in the past 6 months; or, participants who had 2 or more episodes of DIOS in the past year
* Participants with poorly controlled diabetes according to the investigator's opinion
* Female participants who are pregnant or lactating
* Participants who received an investigational drug within 30 days prior to entry into the study
