"This is an exciting time for Halozyme as we focus on advancing our PEGPH20 clinical program and Athena's experience and expertise make her a valuable addition to our team," stated Dr. Helen Torley, President and Chief Executive Officer. "The depth of Athena's medical expertise and her successful track record of advancing novel oncology treatments through the clinical development and regulatory processes make her ideally suited to take on this important role as we seek to execute our growth strategy in 2015 and beyond."

During Athena's career, she has participated in or led the clinical development and approvals of three oncology assets (Bosulif®, Sutent®, and Sprycel®).  Most recently, Dr. Countouriotis served as Chief Medical Officer at Ambit Biosciences (acquired by Daiichi Sankyo in November 2014) where she was responsible for clinical development, and regulatory affairs. In this capacity, Dr. Countouriotis provided leadership to the development and clinical operations strategies for quizartinib, currently in Phase 3 development for Acute Myeloid Leukemia, and served as a key contributor to the successful initial public offering in May 2013.

In this role, she led late-stage clinical development and the approvals for Bosulif in Chronic Myelogenous Leukemia (CML).

Prior to joining Pfizer, Dr. Countouriotis served as a clinical team director at Bristol-Myers Squibb supporting the development and approvals of Sprycel for the treatment of CML. She began her career at Cell Therapeutics, Inc.

"Halozyme is a leader in understanding the critical role that hyaluronan plays in the tumor microenvironment. I am encouraged by the strong non-clinical data and early stage clinical data with PEGPH20, and look forward to working closely with the team to maximize the potential of PEGPH20 for patients with multiple different solid tumors including pancreatic cancer and lung cancer," said Dr. Countouriotis.

Dr. Countouriotis received her M.D. from Tufts University School of Medicine and her bachelor's degree from the University of California, Los Angeles.  She received her initial training in pediatrics at the University of California, Los Angeles, and additional training in the pediatric hematology/oncology program at the Fred Hutchinson Cancer Research Center.
