CAMBRIDGE, Mass., May 29, 2008 – AVEO Pharmaceuticals, Inc., a biotechnology company leveraging breakthrough discoveries in cancer biology to discover, develop and commercialize targeted oncology therapies, today announced that they have completed enrollment in their 200-patient Phase 2 clinical trial of AV-951 in patients with metastatic renal cell carcinoma (mRCC). 

“We are very pleased with the rapid rate at which we accrued patients for this trial,” said Tuan Ha-Ngoc, president and chief executive officer of AVEO.  “The positive Phase 1 data we presented last month at AACR, coupled with the high investigator and patient interest in this Phase 2 trial, suggests a significant market opportunity for a differentiated VEGF receptor inhibitor. Based on our promising, early data, we believe the unique triple VEGF receptor inhibition and tolerability positions AV-951 as a potential best-in-class anti-angiogenic agent. ” 

This placebo-controlled, randomized discontinuation trial is assessing the safety and efficacy of once-daily, oral AV-951 in metastatic renal cell carcinoma patients naïve to VEGF targeted therapy at more than 30 sites in Europe and India under a U.S. investigational new drug (IND) filing.  In this Phase 2 trial, all patients receive 16 weeks of AV-951, after which time patients are evaluated for response, stable disease or progressive disease. Those patients who experience a partial or complete response remain on therapy; those patients who experience stable disease are randomized to receive 12 weeks of AV-951 or placebo in a double-blind fashion.

The primary endpoints of this trial are objective response rate after 16 weeks of treatment, percentage of patients who are progression free at 12 weeks following randomization (i.e. 28 weeks after study entry), and safety.  For more information, please visit the NIH Clinical Trials web site at

About AV-951

AV-951 is a novel, highly potent and specific inhibitor of VEGF receptors 1, 2 and 3. Angiogenesis inhibition has demonstrated benefit for patients with a wide range of cancer types, including renal cell carcinoma, metastatic breast cancer, colorectal cancer, and non-small cell lung cancer.  Due to its specificity, AVEO believes AV-951 may be more readily combined with standard chemotherapy as well as other targeted therapies, potentially increasing the breadth of its clinical utility.  AVEO’s translational research effort, comprising its Human Response Platform (HRP™), offers an opportunity to exploit AV-951’s unique characteristics and will provide further insight into potential clinical settings, combinability with other anti-cancer agents, tumor subtypes and responsive patient populations.

In addition to the ongoing Phase 2 trial, AVEO recently initiated a Phase 1b trial in combination with temsirolimus, an approved mTOR inhibitor, in patients with mRCC.
