ZENPEP® can help your patients with CF absorb the fats, proteins, and vitamins from their food that they need with every meal1,2
Primary Endpoint: Mean Difference in CFA and CNA1,2*
*A randomized, double-blind, placebo-controlled, 2-treatment, crossover study (ZENPEP Study 1) in patients with EPI due to CF aged 7 to 23 years. Patients were randomized to ZENPEP or placebo for 6 to 7 days, followed by crossover to the alternate treatment for 6 to 7 days. All patients consumed ≥100 g of fat per day. The primary efficacy endpoint was the mean difference in CFA between ZENPEP and placebo, which was measured from a 72-hour stool collection during both treatments. The use of enzymes other than ZENPEP and drugs affecting gastric pH or motility were not allowed during the trial.1,2
†One patient did not have fecal fat and nitrogen readings while on placebo.2
Majority of patients achieved a near-normal CFA with ZENPEP: 91% of patients had a CFA above 80%2,3
- Of these patients, 50% achieved a CFA above 90%
As the secondary endpoint of the clinical trial, ZENPEP showed a 22% improvement in mean CNA vs patients taking placebo (P<0.001; 95% CI, 16%-27%)
ZENPEP delivered relief for many EPI-related GI symptoms2‡
reduction in mild abdominal pain
reduction in stool frequency
fewer watery stools
reduction in moderate flatulence
reduction in soft stools
less oil and grease in stools
‡Percentages were derived from actual numbers in referenced data. P values were taken directly from reference.
CF=cystic fibrosis; CFA=coefficient of fat absorption; CI=confidence interval (the range in which we are 95% sure our mean value lies);
CNA=coefficient of nitrogen absorption; EPI=exocrine pancreatic insufficiency; GI=gastrointestinal.
Total Symptoms Index (TSI) score, which assessed overall improvement in the clinical symptoms of EPI, was significantly improved with ZENPEP vs placebo (P=0.015)4
