Porcine derived enzymes are used for pancreatic enzyme replacement therapy in patients with cystic fibrosis (CF). Liprotamase is a biotechnology-derived enzyme replacement without enteric coating. This is an open-label, assessor blind, parallel group, multicenter, international trial to evaluate the noninferiority of liprotamase and pancrelipase in CF patients aged ≥7 years with pancreatic insufficiency. Subjects were randomized to liprotamase or pancrelipase, dose-matched to pre-study lipase doses. The lower bound of the 95% confidence interval (CI) for noninferiority was -15% for treatment difference in change from baseline coefficient of fat absorption (CFA).
