“Today’s name change signals a new day for vascular targeted therapies and our commitment to integrate them into
the cancer treatment paradigm,” said William D. Schwieterman, M.D., President and Chief Executive Officer of Mateon. “Over the past
year, we redefined our clinical and regulatory strategies to position the company and our lead product candidate, CA4P, on what we
believe to be the shortest path towards approval in an indication with the highest probability of success.”
Since joining the company in May 2015, Dr. Schwieterman has built a world-class management and clinical
development team with deep expertise in drug development. Dr. Schwieterman concluded, “With our team and strategy now firmly in
place, we are ready to build upon the work of the past and are committed to realizing the full potential of combination vascular
targeted therapy in orphan oncology indications.”
OXiGENE was named for its founding technology of oxygen-mediated radiosensitizers. The new company name, Mateon
Therapeutics, is derived from the company’s location in San Mateo County, the birthplace of biotechnology.
About Mateon Therapeutics,
Inc.
Mateon Therapeutics, Inc. is a biopharmaceutical company seeking to realize the full potential of vascular
targeted therapy (VTT) in orphan oncology indications. VTT includes vascular disrupting agents (VDAs) such as the investigational
drugs that Mateon is developing, and anti-angiogenic agents (AAs), a number of which are FDA-approved and widely used in cancer
treatment. These two approaches have distinct yet complementary mechanisms of action.
At Mateon, we believe that we can significantly improve cancer therapy by employing these two complementary
approaches in combination. When utilized this way, VDAs disrupt existing blood vessels in the tumor leading to significant central
tumor cell death while AAs prevent the formation of new tumor blood vessels.
Mateon is committed to leveraging our intellectual property and the product development expertise of our highly
experienced management team to enable VTT to realize its true potential and to bring much-needed new therapies to cancer patients
worldwide.
