"The quality of the results generated to date in each of our three ongoing Phase II bavituximab cancer trials is very promising," said Steven W. King, president and CEO of Peregrine. "Our oral presentation today at ASCO exemplifies the heightened interest the bavituximab cancer program is receiving from both clinical researchers and potential partners, and we look forward to reporting on progress and additional results from all three of our Phase II bavituximab studies over the rest of the year."
About Phosphatidylserine (PS)-Targeting Therapies
The rapid and disorganized growth that is the hallmark of cancer results in the exposure of the lipid phosphatidylserine (PS) on the surface of tumor blood vessels. Since these phospholipids are typically not exposed on the surface of normal tissues, they represent a unique target for anti-cancer treatments. Bavituximab is a monoclonal antibody that binds specifically to these phospholipids exposed on the surface of the cells lining tumor blood vessels. Once bound, bavituximab alerts the body's immune system to attack the tumor blood vessels, inhibiting tumor growth and proliferation. In addition, a growing body of evidence supports the active role of PS in immune signaling, with recent research showing that exposed PS can have an immunosuppressive effect and dampen the body's normal response to cancer. By binding to and blocking PS, bavituximab is believed to boost the body's ability to combat cancer via this second immunostimulatory mechanism. Further information on the role of exposed PS in the tumor environment can be found in the Anti-PS Technical Backgrounder posted at
