CAMBRIDGE, Mass., May 31, 2011 (BUSINESS WIRE) — AVEO Pharmaceuticals, Inc. (NASDAQ: AVEO) today announced it has entered into an exclusive license agreement with Centocor Ortho Biotech Inc. for the worldwide development and commercialization of AVEO’s internally-discovered antibodies targeting the RON (Recepteur d’Origine Nantais) receptor. The RON pathway is believed to be involved in several aspects of cancer development including regulation of tumor growth, survival and metastasis, and bone disruption. In preclinical studies, AVEO’s proprietary anti-RON antibodies have demonstrated strong anti-tumor activity.

AVEO is initially receiving $15 million. Under the terms of the license agreement, AVEO will receive the first half of this amount as an up-front payment from Centocor Ortho Biotech. Through a separate equity private placement and stock purchase agreement, the second half will be received through the sale of newly issued shares of AVEO common stock to an affiliate of Centocor Ortho Biotech, Johnson & Johnson Development Corporation. Under the license agreement, AVEO is eligible to receive up to $540 million in milestone payments based upon the achievement of specified development, regulatory and commercialization goals. Upon commercialization, AVEO will be entitled to a tiered, double-digit royalty on net sales worldwide. Centocor Ortho Biotech will be responsible for all clinical development, manufacturing, and commercialization activities and costs. Centocor Ortho Biotech will also fund certain research conducted by AVEO, including translational research studies using its Human Response Platform(TM) to identify biomarkers for patients most likely to benefit from treatment with RON-targeted antibodies.

“We are delighted to enter into this strategic alliance,” said Elan Ezickson, executive vice president and chief business officer of AVEO. “We believe that the RON pathway is a promising novel target for combating cancer growth and progression. This license agreement highlights the broad potential of our unique monoclonal antibody R&D capabilities and further supports AVEO’s strategy to maximize our proprietary cancer biology platform to build a sustainable cancer therapeutics company.”

RON, or MST1R, receptor tyrosine kinase is a member of the c-MET RTK family. Published research has shown that over-expression of RON has been observed in multiple solid tumor types including breast, colorectal, non-small cell lung, glioblastoma multiforme (GBM), prostate, pancreatic, ovarian and bladder cancers, and is associated with disease progression and metastasis.

AVEO’s research of RON biology has been aided by its novel, genetically defined, in vivo murine tumor models and related bioinformatics tools. In AVEO’s proprietary in vivo models, both wild-type RON and RON160 have been shown to potently drive tumor growth, with AVEO’s anti-RON antibodies demonstrating strong anti-tumor activity. AVEO has also utilized its unique bioinformatics tools for biomarker research and to generate a RON pathway gene index that quantifies the level of RON pathway activation. AVEO has used this index to identify human tumor cell lines with high RON pathway activity, and has demonstrated in preclinical models that the inhibition of RON function by anti-RON antibodies potently inhibited tumor cell growth and survival. These studies provided preclinical evidence of the potential benefits of RON inhibition and identified a genetic context in which RON inhibition may have therapeutic benefit.

About AVEO

AVEO Pharmaceuticals (NASDAQ: AVEO) is a cancer therapeutics company committed to discovering, developing and commercializing targeted therapies to impact patients’ lives. The company’s lead product candidate, tivozanib, is currently being investigated in a global, randomized Phase 3 clinical trial called TIVO-1 comparing tivozanib to sorafenib in patients with advanced renal cell carcinoma, as well as additional clinical studies in other solid tumor types. AVEO’s second most advanced product candidate, ficlatuzumab (AV-299), is a potent, functional anti-HGF/c-MET pathway antibody that is currently in Phase 2 clinical development. AVEO’s proprietary Human Response Platform(TM) is designed to offer the company a unique advantage in cancer drug development and has provided a discovery engine for multiple therapeutic targets. This approach has resulted in a promising pipeline of monoclonal antibodies against novel targets including HGF, ErbB3, RON, Notch and FGFR.
