Liprotamase Long‐term Safety and Support of Nutritional Status in Pancreatic‐insufficient Cystic Fibrosis

ABSTRACT Objectives: Patients with cystic fibrosis (CF) who have exocrine pancreatic insufficiency (EPI) require treatment with pancreatic enzyme replacement therapy (PERT) to maintain adequate nutrition and age‐appropriate growth and weight gain.

description ABSTRACT Objectives: Patients with cystic fibrosis (CF) who have exocrine pancreatic insufficiency (EPI) require treatment with pancreatic enzyme replacement therapy (PERT) to maintain adequate nutrition and age‐appropriate growth and weight gain. Liprotamase, a nonporcine, highly purified biotechnology‐derived PERT, has demonstrated significant efficacy in fat and protein malabsorption in patients with EPI compared to placebo. This study of liprotamase is the first ever long‐term trial of a PERT to evaluate safety and nutritional parameters. Methods: This phase III 12‐month open‐label trial assessed the safety, tolerability, and long‐term nutritional effects of liprotamase treatment in patients with CF and EPI 7 years and older. All of the patients were required to discontinue their long‐term use of porcine PERTs at the time of enrollment. Dosing started at 1 capsule of liprotamase (32,500 US Pharmacopoeia (USP) units crystallized cross‐linked lipase, 25,000 USP units crystallized protease, and 3,750 USP units amorphous amylase) per meal or snack; dose could be increased based on protocol‐defined parameters. Results: A total of 215 subjects were enrolled and 214 received at least 1 dose of liprotamase (mean 5.5 capsules per day). During the study period, height, weight, and body mass index z scores and lung function as measured by forced expiratory volume in 1 second were stable. There were no clinically meaningful changes in laboratory tests, including levels of fat‐soluble vitamins. Liprotamase was well tolerated without any significant safety concerns. Adverse events, primarily gastrointestinal, led to treatment discontinuation for 36 subjects (16.8%), most within the first 3 months. Conclusions: Treatment with a mean of 5.5 capsules of liprotamase per day, during meals and snacks, for up to 12 months was safe, well tolerated, and associated with age‐appropriate growth and weight gain or weight maintenance in subjects with CF‐related EPI.
