EUR-1008 (APT-1008) (Zenpep® [pancrelipase] 3,000 lipase units delayed release capsules) from open capsules mixed with a small amount of apple juice or apple sauce will be administered orally starting at the same dose as administered at the end of study PR-011 (NCT01100606), with dose increments of 3,000 lipase units. The dose will be adjusted based on participants' age and body weight. Total dose will not exceed 10,000 lipase units per kilogram (kg) of body weight per day unless clinically indicated. Total duration of study treatment will be up to 12 months.

TEAE was any event not present prior to exposure to study drug or any event already present that worsened in either intensity or frequency following exposure to test drug. Serious AE (SAE) was any event that resulted in death, immediately life threatening, hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, or a congenital anomaly/birth defect. Number of participants with TEAEs, SAEs, TEAE's relationship to study drug (unrelated, possible and probable) and on the basis of severity (mild [minimal/no treatment and did not interfere with daily activities], moderate [resulted in a low level of inconvenience or concern with the therapeutic measures and may have caused some interference with functioning] and severe [interrupted participant's usual daily activity, may have required systemic drug therapy or other treatment and were usually incapacitating]) with a frequency threshold of above 5% were reported.

Participant's ability to thrive was evaluated through growth percentiles for weight-for-age, length-for-age and weight-for-length recorded on Center for Disease Control and Prevention (CDC) growth charts during each treatment visit.
