• First three patients enrolled in dose escalation trial using delayed-release enteric capsules
  • Topline data expected in 1H 2021

NEW YORK, NY, USA I August 13, 2020 I AzurRx BioPharma, Inc. (NASDAQ:AZRX) (“AzurRx” or the “Company”), a company specializing in the development of non-systemic, recombinant therapies for gastrointestinal diseases, today announced that is has enrolled the first three patients in its Phase 2b OPTION 2 clinical trial to investigate MS1819 in cystic fibrosis (CF) patients with exocrine pancreatic insufficiency (EPI). The trial will enroll approximately 30 CF patients with top line data from the study anticipated in 1H 2021.

The Phase 2b multi-center study is designed to investigate the safety, tolerability, and efficacy of MS1819 (2.2 gram and 4.4 gram doses in enteric capsules) in a head-to-head comparison against the current porcine enzyme replacement therapy (PERT) standard of care.  The primary efficacy endpoint is the coefficient of fat absorption (CFA), with secondary endpoints of stool weight, signs and symptoms of malabsorption and coefficient of nitrogen absorption (CNA).

“Enrolling the first patient in our Phase 2b OPTION 2 trial is an important milestone and we appreciate the support from our clinical trial specialists and centers. We are optimistic that our delayed-release delivery of MS1819 will achieve our primary and secondary efficacy endpoints in this study,” said Dr. James Pennington, Chief Medical Officer of AzurRx. “We anticipate data from this trial will inform the optimal dose for our pivotal Phase 3 study, and look forward to top line results in the first quarter of next year.”

James Sapirstein, Chief Executive Officer of AzurRx, added, “We are very pleased to announce that patient dosing in the OPTION 2 trial has begun in the U.S. This represents an important milestone in the clinical development of MS1819 as an EPI monotherapy for patients with cystic fibrosis. Despite the challenges posed by the COVID-19 pandemic, the AzurRx team has been able to successfully activate new clinical trial sites and work with investigators to safely admit patients into the trial.”

Phase 2 OPTION 2 Trial Design
The Phase 2b OPTION 2 multi-center trial is designed to investigate the safety, tolerability and efficacy of MS1819 (2.2 and 4.4 gram doses in enteric capsules) in a head-to-head comparison versus the current standard of care, porcine pancreatic enzyme replacement therapy pills. The OPTION 2 trial will be an open-label, crossover study, conducted in 15 sites in the U.S. and Europe. A total of 30 CF patients 18 years or older will be enrolled.  MS1819 will be administered in enteric capsules to provide gastric protection and allow optimal delivery of enzyme to the duodenum.  Patients will first be randomized into two cohorts: to either the MS1819 arm, where they receive a 2.2 gram daily oral dose of MS1819 for three weeks; or to the PERT arm, where they receive their pre-study dose of PERT pills for three weeks. After three weeks, stools will be collected for analysis of coefficient of fat absorption. Patients will then be crossed over for another three weeks of the alternative treatment. After three weeks of cross-over therapy, stools will again be collected for analysis of CFA. A parallel group of patients will be randomized and studied in the same fashion, using a 4.4 gram daily dose of MS1819.  All patients will be followed for an additional two weeks after completing both crossover treatments for post study safety observation. Patients will be assessed using descriptive methods for efficacy, comparing CFA between MS1819 and PERT arms, and for safety.

About MS1819
MS1819 is a recombinant lipase enzyme for the treatment of exocrine pancreatic insufficiency associated with cystic fibrosis and chronic pancreatitis. MS1819, supplied as an oral non-systemic biologic capsule, is derived from the Yarrowia lipolytica yeast lipase and breaks up fat molecules in the digestive tract of EPI patients so that they can be absorbed as nutrients. Unlike the standard of care, the MS1819 synthetic lipase does not contain any animal products.

About Exocrine Pancreatic Insufficiency
EPI is a condition characterized by deficiency of the exocrine pancreatic enzymes, resulting in a patient’s inability to digest food properly, or maldigestion. The deficiency in this enzyme can be responsible for greasy diarrhea, fecal urge and weight loss.

There are more than 30,000 patients in the U.S. with EPI caused by cystic fibrosis according to the Cystic Fibrosis Foundation and approximately 90,000 patients in the U.S with EPI caused by chronic pancreatitis according to the National Pancreas Foundation. Patients are currently treated with porcine pancreatic enzyme replacement pills.
