Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Panzytrat® 25,000	Drug: Panzytrat® 25,000; Panzytrat® 25,000 capsule will be given orally daily at a stabilized dose, as per investigator's discretion, for 14 days. Stabilized dose for a participant will be the optimal dose determined during a qualification phase that precedes the first treatment period and will be based upon the participant's usual lipase and lipid intake. Total dose will not exceed 10,000 European Pharmacopoeia (Ph.Eur.) units lipase/kilogram (kg) body weight/day in either first treatment period or second treatment period.
Active Comparator: Kreon® 25,000	Drug: Kreon® 25,000; Kreon® 25,000 capsule will be given orally daily at a stabilized dose, as per investigator's discretion, for 14 days. Stabilized dose for a participant will be the optimal dose determined during a qualification phase that precedes the first treatment period and will be based upon the participant's usual lipase and lipid intake. Total dose will not exceed 10,000 Ph.Eur. units lipase/kg body weight/day in either first treatment period or second 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 in the stools which were collected over a 3-day period (Day 12 to morning of Day 15) during each treatment period. Least squares mean percent (%) CFA was calculated for Day 12 to Day 15 in first and second treatment periods. Percent CFA was based on log transformed data.	Day 12 up to Day 15 in first and second treatment periods

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean Daily Number of Stools	Mean daily number of stools of each participant was calculated from frequency of stools by the participant per day. Mean daily number of stools during the collection period (Day 12 to Day 15 in first and second treatment periods) for total participants was summarized.	Day 12 up to Day 15 in first and second treatment periods
Percentage of Stools With Normal Consistency	Normal consistency of stool was defined as formed hard, normal or soft stool and abnormal consistency was defined as loose and unformed, liquid stool and diarrhea. Percentage of stools with normal consistency of each participant was calculated as the number of stools with normal consistency relative to the total number of stools during the collection period. Mean percentage of stool with normal consistency during the collection period (Day 12 to Day 15 in first and second treatment periods) for total participants was summarized.	Day 12 up to Day 15 in first and second treatment periods
Total Weight of Stools	Mean total weight of stools was calculated for Day 12 to Day 15 in first and second treatment periods.	Day 12 up to Day 15 in first and second treatment periods
Mean Weight Per Stool Sample	Mean weight per stool sample was calculated for Day 12 to Day 15 in first and second treatment periods.	Day 12 up to Day 15 in first and second treatment periods
Relative Frequency of Days With Abdominal Symptoms	Abdominal symptoms included abdominal pain and flatulence. Symptoms were classified by severity as mild (no impairment of daily activities), moderate (slight impairment of daily activities), or severe (unable to perform daily activities). For each type of abdominal symptom, the relative frequency of days with the symptom for each participant in a treatment period was calculated as the number of days in which the symptom was reported divided by the total number of days in which the abdominal symptom case report form (CRF) was completed. Mean relative frequency of days with abdominal symptoms was calculated during each treatment period (Day 1 to Day 15).	Day 1 up to Day 15 in first and second treatment periods
Percentage of Participants With Abdominal Distension	Abdominal distension is a sense of increased abdominal pressure by the participant that involves an actual measurable change in the circumference of a participant's abdomen on physical examination. Percentage of participants with abdominal distension was calculated for each treatment period (Day 1 to Day 15).	Day 1 up to Day 15 in first and second treatment periods
Percent Coefficient of Fat Absorption (CFA) Based on Concomitant Use of Proton Pump Inhibitors (PPIs)	Percent CFA was calculated as ([fat intake - fat excretion]/fat intake)*100, determined in the stools which were collected over a 3-day period (Day 12 to morning of Day 15) during each treatment period. Least squares mean percent (%) CFA was calculated for Day 12 to Day 15 in first and second treatment periods. Percent CFA was based on log transformed data. Percent CFA was calculated separately for participants who used and did not use acid suppressing therapy (PPIs) during the study.	Day 12 up to Day 15 in first and second treatment periods
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) or Serious Adverse Events (SAEs)	An AE was defined as any untoward medical occurrence regardless of its causal relationship to study drug. A TEAE was defined as any event not present prior to exposure to study drug or any event already present that worsens in either intensity or frequency following exposure to test drug. A SAE was defined as any event that results in death, is immediately life threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, or is a congenital anomaly/birth defect or is assessed as medically important.	Baseline up to 30 days after last dose
Nutritional Status as Assessed by Body Weight	Mean body weight was calculated at end of treatment (within 3 days after Day 15 of first and second treatment periods).	Baseline, end of treatment (within 3 days after Day 15 of first and second treatment periods) or early discontinuation
Nutritional Status as Assessed by Body Mass Index (BMI)	Nutritional status of participants was assessed by determining their BMI. BMI was calculated by dividing body weight (kg) by square of height in meter (m). Mean BMI was calculated at end of treatment (within 3 days after Day 15 of first and second treatment periods).	Baseline, end of treatment (within 3 days after Day 15 of first and second treatment periods) or early discontinuation
Nutritional Status as Assessed by Electrolytes Level	Nutritional status of participants was assessed by determining their electrolytes (sodium, potassium and chloride) level. Mean electrolytes level was calculated at end of treatment (within 3 days after Day 15 of first and second treatment periods).	Baseline, end of treatment (within 3 days after Day 15 of first and second treatment periods) or early discontinuation
Nutritional Status as Assessed by Albumin, Serum Transferrin and Hemoglobin Level	Nutritional status of participants was assessed by determining their albumin, serum transferrin and hemoglobin level. Mean albumin, serum transferrin and hemoglobin level was calculated at end of treatment (within 3 days after Day 15 of first and second treatment periods).	Baseline, end of treatment (within 3 days after Day 15 of first and second treatment periods) or early discontinuation
Nutritional Status as Assessed by Hematocrit Level	Nutritional status of participants was assessed by determining their hematocrit level. Mean hematocrit level was calculated at end of treatment (within 3 days after Day 15 of first and second treatment periods).	Baseline, end of treatment (within 3 days after Day 15 of first and second treatment periods) or early discontinuation
