Two enteric coated microspheres in cystic fibrosis

Area of Science:

• Pediatric Gastroenterology
• Cystic Fibrosis Research
• Pharmacology

Background:

• Cystic fibrosis (CF) often leads to pancreatic insufficiency, requiring enzyme replacement therapy.
• Pancreatic enzyme preparations are crucial for managing malabsorption in CF patients.
• Enteric-coated microsphere formulations aim to improve enzyme delivery and efficacy.

Purpose of the Study:

• To compare the efficacy of two enteric-coated pancreatin microsphere preparations, Pancrease and Creon.
• To evaluate differences in fat absorption, nitrogen excretion, weight change, and symptom scores.
• To determine if Pancrease and Creon are bioequivalent on a capsule-for-capsule basis.

Main Methods:

• A randomized, single-blind, crossover study design was employed.
• Thirty-nine children with cystic fibrosis and pancreatic insufficiency participated.
• Key efficacy measures included coefficient of fat absorption, nitrogen excretion, weight change, and symptom scores over four-week treatment periods for each preparation.

Main Results:

• Data from 27 children were analyzed.
• No statistically significant differences were observed between Pancrease and Creon for any of the measured variables.
• Both preparations demonstrated comparable effects on fat absorption, nitrogen excretion, weight gain, and symptom management.

Conclusions:

• Pancrease and Creon exhibit comparable efficacy when administered on a capsule-for-capsule basis in children with cystic fibrosis.
• The findings suggest no significant clinical advantage of one preparation over the other.
• Further research may explore patient-reported outcomes or long-term efficacy.
