Eurand Announces Positive Phase III Clinical Study Results
MILAN, Italy and DAYTON, Ohio, April 04, 2007 /PRNewswire/ -- Eurand, a global specialty pharmaceutical company, today unveiled data from two phase III clinical trials on its lead product candidate, Zentase(TM), formerly EUR-1008, for the treatment of Exocrine Pancreatic Insufficiency (EPI). The US Food and Drug Administration (FDA) granted fast track status for Zentase for the treatment of EPI. The company intends to file for FDA approval during the second quarter of 2007 for this potentially first-in-class pancreatic enzyme replacement therapy.
Zentase is a zero-overfill, highly-stable, porcine-derived pancreatic enzyme replacement therapy used to treat EPI and was designed to meet FDA guidelines for pancreatic enzyme replacement products(1). According to the FDA, no currently marketed pancreatic enzyme product (PEP) has been shown to demonstrate consistent enzyme bioactivity that results in predictable safety and effectiveness(2). Many of the current enzyme products contain overfill to compensate for product instability during shelf life, which can lead to variability in dosing. As a highly-stable product, Zentase does not require overfill. Currently, there are no FDA approved PEPs for the treatment of EPI on the market in the US.
"We are excited to present the results of our phase III studies supporting Zentase for the full spectrum of cystic fibrosis patients suffering from EPI, including those needing limited supplementation to those with very aggressive enzyme deficiency," said Gearoid Faherty, Eurand Chairman and CEO.
Zentase met all primary and secondary endpoints in two phase III clinical trials. The studies were designed to determine whether the product candidate could alleviate serious malabsorption associated with EPI in both a pediatric (younger than 7 years) and an older patient population.
Study results showed a clinically and statistically significant increase in the coefficient of fat absorption (CFA) in patients treated with Zentase. The mean percentage of CFA in patients receiving Zentase was 88.3 percent versus 62.8 percent in patients receiving placebo (p<0.001). Treatment guidelines suggest that the CFA should be at least 85 percent in cystic fibrosis (CF) patients(3).
"The protocols for these trials were reviewed by the FDA and developed in collaboration with the Cystic Fibrosis Foundation (CFF). We want to thank the CFF for their support," added Faherty.
Phase III Pivotal Study Results
This randomized, double-blind, placebo-controlled, cross-over study evaluated CF patients with EPI aged seven years and older. Patients treated with Zentase showed a statistically significant increase in the coefficient of fat absorption and coefficient of nitrogen absorption (CNA) as compared to those receiving a placebo. They also had fewer symptoms associated with impaired absorption such as bloating, flatulence, pain and evidence of fat in stools.
Moreover, in all study patients, regardless of starting levels while taking placebo, Zentase returned CFA and CNA absorption levels to ranges considered normal in healthy patients. We believe this suggests Zentase can provide the level of enzyme supplementation required by cystic fibrosis patients with different levels of EPI.
"I believe the results of this successful trial demonstrated the efficacy and safety of Zentase," said James E. Heubi, MD, Professor and Associate Chair for Clinical Research of Pediatrics at Children's Hospital Medical Center in Cincinnati, OH. "During the study, the level of fat absorption achieved with Zentase was very high and close to levels seen in healthy patients, even without the use of proton pump inhibitors (PPIs). This high fat absorption, without relying on PPIs could significantly reduce the number of pills patients take each day."
Phase III Pediatric Supportive Study Results
This open label study in CF patients under the age of seven involved a seven-day dose stabilization period followed by a seven-day treatment period. The study evaluated the percentage of "responders," or those patients without excess fat in stools and without signs and symptoms of malabsorption after one and two weeks of treatment. Secondary endpoints included weight change, nutritional status, stool frequency and consistency, incidences of bloating, pain and flatulence as well as physician and parent or guardian judgment of clinical symptoms improvement.
In the study, malabsorption symptoms were significantly lower at the end of treatment than at screening, consistent with control of malabsorption symptoms with Zentase in the pivotal phase III trial.
EPI and Cystic Fibrosis
EPI is a deficiency of digestive enzymes normally produced by the pancreas. The deficiency leads to malnutrition, impaired growth in children and shortened life expectancy. EPI is commonly associated with cystic fibrosis and chronic pancreatitis.
Cystic Fibrosis affects about 30,000 individuals in the US and 100,000 worldwide. Approximately 90 percent of these individuals suffer from EPI. Treatment with PEPs helps replace enzymes lost through this disease. Other than enzyme replacement, Eurand is not aware of any other alternative therapy for EPI.
Zentase is a zero-overfill, highly-stable, porcine-derived pancreatic enzyme replacement therapy designed to treat EPI, a deficiency of digestive enzymes normally produced by the pancreas.
Zentase closely mimics the enzyme profile of normal human pancreatic secretions. Formulated with eight key enzymes and other co-enzymes and cofactors required for proper digestion, Zentase is highly stable and requires no product overfill. The product is being developed in multiple strengths as well as a pediatric formulation, which can be sprinkled on food for easier administration to young children.
The full results of the two phase III trials will be published in peer reviewed journals and presented at upcoming medical meetings in the United States and Europe.
