AVEO Pharmaceuticals Novel Oncology Research Platform and Clinical Pipeline to Be Featured at AACR.

Data to be Featured in Five Oral Presentations and Seven Poster Sessions

CAMBRIDGE, Mass. -- AVEO Pharmaceuticals, Inc., a biopharmaceutical company focused on the discovery and development of novel, targeted cancer medicines, announced today that it will present a total of 12 oral and poster presentations at the American Association for Cancer Research (AACR) Annual Meeting on April 14-18, 2007, in Los Angeles, California.

"We are very excited to share with the cancer community the pioneering oncology research platform AVEO has developed, which we believe may significantly enhance the probability of success and the efficacy of the next generation of targeted cancer therapies," said Tuan Ha-Ngoc, president and CEO of AVEO Pharmaceuticals. "AVEO is focusing on translating this groundbreaking science into new drugs that may have a significant impact on cancer patient care and more importantly, patient response and outcomes."

These presentations focus on several applications of AVEO's breakthrough Human Response Prediction[TM] Platform of in vivo inducible mouse models.

About AVEO

AVEO is a private biopharmaceutical company focused on the discovery and development of novel, targeted cancer therapeutics. The company utilizes its proprietary, genetically-defined cancer models for the identification and validation of novel cancer targets, and has begun to build an impressive portfolio of drug discovery and development programs around these high-value targets. AVEO also uses its Human Response Prediction[TM] Platform to identify genetic profiles that correspond with patient responsiveness. AVEO expects to commence Phase 2 clinical studies by mid-2007 for AV-951, its oral, second-generation VEGF receptor inhibitor and most advanced clinical program. AV-412, AVEO's EGFR/HER2 inhibitor, is currently in Phase I clinical trials. AV-299, a novel anti-HGF mAb, is currently being manufactured by XOMA under a supply agreement in anticipation of entering the clinic in early 2008. AVEO is located in Cambridge, Massachusetts.
