General information about the trial
|
|||
Main objective of the trial |
To assess the therapeutic equivalence of Creon N 25000 with Creon® 25000 on coefficient of fat absorption (CFA) in adolescent and adult subjects with pancreatic exocrine insufficiency (PEI) due to cystic fibrosis (CF).
|
||
Protection of trial subjects |
All study investigators expressly agreed not to disclose the identity of the patients treated and to abide by the confidentiality rules as regards data and information to which they had access by participating in the study.
All the data related to the participating patients were recorded and treated according to the regulatory law of data protection.
All information obtained as a result of this study was considered confidential until the sponsor deemed it appropriate. The investigator could only inform on the study conduct and results to the sponsor, EC, and regulatory authorities.

Background therapy |

Evidence for comparator |
Creon capsules contain pancreatin which is released in the stomach. The particles mix with the chyme in the stomach and do not dissolve due to the pH-resistant enteric coating. Upon entering the duodenum the coating dissolves to release the enzymes for food digestion, dependent on the pH of the duodenum. The pH-sensitive enteric-coated minimicrospheres have been developed to improve the delivery of active enzymes to the small intestine. | ||

Dosage and administration details |
Creon N 2500 was administered during the course of the meals and snacks. The capsules should be swallowed intact, without crushing or chewing, with enough fluid during or after each meal or snack. In-between the two-treatment periods, there was a wash-out period of 3 to 14 days where the subjects were treated with their usual pancreatic enzyme supplementation in the usual dose.

End point description |
The primary objective was to show that Creon N and Creon R were equivalent with regard to the coefficient of fat absorption (CFA). To prove equivalence, the 95% confidence interval for the treatment difference had to lie entirely within the equivalence range (-8%, 8%)
