EUR-1008 (APT-1008) microtablets (5000 lipase units) or minitablets (10000, 15000 or 20000 lipase units) contained in a capsule will be given orally daily in first double-blind intervention period; at a dose based on investigator's discretion as achieved during dose titration and stabilization period (6 to 9 days). The capsules could be opened and sprinkled on acidic food and half of the established dose was used with snacks. Treatment duration for first double-blind intervention period will be 2 days home treatment and 3 to 5 days hospital treatment.

Placebo matched to EUR-1008 (APT-1008) microtablets or minitablets contained in a capsule will be given orally daily in second double-blind intervention period; at a dose based on investigator's discretion as achieved during dose titration and stabilization period (6 to 9 days). Treatment duration for second double-blind intervention period will be 2 days home treatment and 3 to 5 days hospital treatment.
