Targeted Antibody Bavituximab to Be Evaluated in Combination With Pemetrexed and Carboplatin for Front-Line Non-Small Cell Lung Cancer
TUSTIN, CA, USA and CHAPEL HILL, NC, USA | March 8, 2011 | Peregrine Pharmaceuticals, Inc. (NASDAQ:PPHM – News), a clinical-stage biopharmaceutical company developing first-in-class monoclonal antibodies for the treatment of cancer and viral infections, today announced the initiation of an investigator-sponsored trial (IST) for patients with chemotherapy naive stage IV non-squamous non-small cell lung cancer (NSCLC). This Phase Ib trial will treat up to 25 front-line NSCLC patients with Peregrine’s investigational monoclonal antibody bavituximab in combination with the chemotherapeutic agents pemetrexed and carboplatin.
"We are encouraged by the prior lung cancer data on bavituximab in combination with chemotherapy and look forward to evaluating the safety and potential efficacy of bavituximab in combination with pemetrexed and carboplatin as an additional therapeutic option in the front-line treatment setting," said Juneko E. Grilley-Olson, M.D., lead investigator of this trial and assistant professor of hematology and oncology at the University of North Carolina at Chapel Hill. "Chemotherapy has been shown to increase the exposure of phosphatidylserine (PS) on tumor blood vessel cells, upregulating the exposure of bavituximab’s PS target. We are eager to evaluate this new combination therapy regimen for the treatment of this deadly form of cancer."
In a prior Phase II trial treating 49 front-line NSCLC patients with bavituximab in combination with a different chemotherapeutic regimen, carboplatin and paclitaxel, overall tumor response rate (ORR) was 43% as measured by RECIST criteria and median progression-free survival (PFS) was 6.1 months. Currently, bavituximab is being evaluated in four randomized Phase II trials, including front-line NSCLC, second-line NSCLC, pancreatic cancer, and HCV and in two other investigator-sponsored trials in advanced liver cancer and HER2-negative metastatic breast cancer.
"This new IST is important as it augments our overall clinical experience in treating patients with bavituximab, especially as we conduct our two randomized Phase IIb trials in NSCLC," said Joseph S. Shan, vice president, clinical and regulatory affairs at Peregrine Pharmaceuticals. "We are excited to have Dr. Grilley-Olson and her team evaluate this therapeutic combination as an additional potential treatment combination for patients with metastatic lung cancer."
About the Phase Ib NSCLC Trial
In this Phase Ib single-arm, open-label trial, up to 25 patients with previously untreated locally advanced or metastatic non-squamous NSCLC will receive up to six 21-day cycles of the drugs pemetrexed and carboplatin with weekly bavituximab until progression or toxicity. The primary endpoint of the study is to determine the safety, dose-limiting toxicity (DLT) and recommended Phase II dose of bavituximab in combination with carboplatin and pemetrexed in advanced non-squamous NSCLC. Secondary endpoints include assessment of overall response rate (ORR) measured by RECIST criteria, progression-free survival (PFS) and overall survival (OS) and exploratory biomarkers.

About Lung Cancer
Lung cancer is the leading cause of cancer death. According to the American Cancer Society, lung cancer is the second most commonly diagnosed cancer, with approximately 219,440 new cases and 159,000 deaths each year in the U.S. NSCLC is the most common type of lung cancer, accounting for approximately 85-90% of lung cancer cases.
