Analysis of data expected in early 2019

TUCSON, Ariz.--(BUSINESS WIRE)-- Cancer Prevention Pharmaceuticals, Inc. (CPP), a private biotech company developing novel therapeutics to prevent cancer and other diseases, announced today the last patient has completed the study protocol in its pivotal Phase 3 trial of CPP-1X/sul for adults with familial adenomatous polyposis (FAP), a rare genetic disease that, if left untreated, progresses to colorectal cancer in nearly 100% of patients.

Analysis of the results from the randomized, double-blind trial are expected to be complete in early 2019, followed by potential submission of a New Drug Application (NDA) with the US Food and Drug Administration (FDA), which has granted CPP-1X/sul for the treatment of FAP fast track and orphan drug designation.

“This is a significant milestone in our development of CPP-1X/sul,” said CPP Chairman and CEO Jeff Jacob. “It has taken five years across multiple sites in the United States, Canada and Europe to complete the trial. We look forward to bringing to FAP patients a pharmaco-prevention therapeutic that, if approved, could change the treatment paradigm for their debilitating and life-threatening disease.”

FAP occurs in about 1 in 10,000 people. For most FAP patients, current medical practice recommends a lifetime of periodic monitoring as well as surgeries (FAP-related events). These FAP-related events include surgical removal of the colon, rectum, surgical pouch, duodenum and/or high-risk adenomas.

“Patients currently suffering from FAP have no effective treatments to delay or prevent progression of their disease,” said Carol A. Burke, MD, a gastroenterologist at the Cleveland Clinic and principal investigator for the FAP-310 clinical trial. “If the study results are favorable and CPP-1X/sul is approved by the FDA, clinicians will be able to offer their FAP patients a safe and effective drug treatment that may reduce or potentially avoid the need for complex endoscopic or surgical intervention.”

The FAP-310 clinical trial, which enrolled 171 patients at 17 research institutes in the United States, Canada and Europe, is the largest-ever FAP clinical trial and treated patients for longer than any other trial. It was designed to determine if CPP-1X (eflornithine) in combination with sulindac is superior to sulindac or eflornithine as single agents in delaying time to the first occurrence of any FAP-related event.

CPP has licensed North American development and commercialization rights for CPP-1X/sul to Mallinckrodt Pharmaceuticals, through its Sucampo AG subsidiary. CPP retains all rights elsewhere.
