SAN DIEGO, April 23, 2013 /PRNewswire/ -- Halozyme Therapeutics, Inc. (NASDAQ: HALO) today announced the initiation of a Phase 2 multicenter, randomized clinical trial evaluating PEGPH20, a proprietary, investigational drug, as a first-line therapy for patients with stage IV metastatic pancreatic cancer. Approximately 124 patients will participate in the study and receive gemcitabine and nab-paclitaxel either with or without PEGPH20. The primary outcome will be to measure progression-free survival between patients administered PEGPH20 to those who are not.
"Pancreatic cancer is an extremely difficult disease to treat, in part because of a hyaluronan-rich matrix which shields these tumors against chemotherapy," said Daniel D. Von Hoff, M.D., F.A.C.P., lead principal investigator of the study and Chief Scientific Officer for Scottsdale Healthcare's Virginia G. Piper Cancer Center Clinical Trials and Physician-In-Chief for the Translational Genomics Research Institute (TGen). "Ongoing translational studies indicate that PEGPH20 may deplete this matrix component from pancreatic tumors and alter the tumor environment in a way that renders these cancers more vulnerable to therapy."
In most patients presenting with metastatic pancreatic adenocarcinoma, survival rates are the lowest of any cancer. In 2013, it is estimated that almost 45,000 new cases of pancreatic cancer will be diagnosed. About one-in-78 people in the U.S. will develop the disease, affecting equal numbers of men and women. Its tendency to spread prior to diagnosis makes it the fourth deadliest cancer with a less than 6% five-year relative survival rate, with more than 38,000 people succumbing to the disease each year. 1-2"We are hopeful that these studies with PEGPH20 will improve patient outcomes for this insidious disease while advancing our general understanding of the unique tumor environment," said Gregory I. Frost, Ph.D., President and Chief Executive Officer, Halozyme. Halozyme recently completed enrollment of a single-arm Phase 1B trial in a similar patient population treated with PEGPH20 and gemcitabine. Two abstracts have been submitted and a discussion session from this study has been selected for the 2013 American Society of Clinical Oncology (ASCO) annual meeting May 31–June 4 in Chicago.
