AVEO Announces Acceptance of CANbridge Investigational New Drug Application for CAN017 (AV-203) Trial in Esophageal Squamous Cell Cancer (ESCC) in China

AVEO Oncology (Nasdaq: AVEO) today announced that the China National Drug Administration (CNDA) has accepted CANBridge Life Sciences’ Investigational New Drug (IND) Application for a Phase Ib/III clinical trial of CAN017 (AV-203), AVEO’s clinical-stage ErbB3 (HER3) inhibitory antibody candidate, in esophageal squamous cell cancer (ESCC).

Under the terms of a March 2016 agreement, the acceptance of this IND triggers a $2 million milestone payment to AVEO from CANbridge Life Sciences. CANbridge licensed worldwide rights, excluding the United States, Canada, and Mexico, to AV-203 from AVEO and AVEO is eligible to receive up to $40 million in potential additional development and regulatory milestone payments and up to $90 million in potential commercial milestone payments, assuming the successful achievement of specified development, regulatory and commercialization objectives.

“CANbridge continues to make progress in advancing CAN017, and we look forward to the initiation of a Phase Ib/extension clinical trial in ESCC, a large unmet medical need globally with a particularly acute need in Asia,” said Michael Bailey, president and chief executive officer of AVEO. “Together with ficlatuzumab, our partnered oncology programs allow us to retain meaningful rights to a promising pipeline and advance it at little or no cost to AVEO, allowing us to focus resources on our tivozanib strategy, including U.S. registration for kidney cancer as well as combinations with immunotherapy.”

AVEO previously completed a Phase 1, open-label, dose-escalation study of AV-203 (CAN017) in patients with advanced solid tumors. In this study, AV-203 was found to be generally safe and well-tolerated, with an early signal of activity consistent with preclinical data showing the potential for heregulin or neuregulin, the only known ligand for ErbB3, to serve as a biomarker predictive of AV-203 anti-tumor activity.

AVEO will pay percentage of the milestone payment to Biogen Idec International GmbH as a sublicensing fee.

About AVEO

AVEO Pharmaceuticals, Inc. (the “Company”) is a biopharmaceutical company dedicated to advancing a broad portfolio of targeted medicines for oncology and other areas of unmet medical need. The Company’s strategy is to retain North American rights to its oncology portfolio while securing partners in development and commercialization outside of North America. The Company is seeking to develop and commercialize its lead candidate tivozanib in North America as a treatment for advanced renal cell carcinoma (“aRCC”). The Company has outlicensed tivozanib (FOTIVDA^®) for oncology in Europe and other territories outside of North America. Tivozanib is approved in the European Union, as well as Norway and Iceland, for the first-line treatment of adult patients with aRCC and for adult patients who are vascular endothelial growth factor receptor and mTOR pathway inhibitor-naïve following disease progression after one prior treatment with cytokine therapy for aRCC. The Company has entered into partnerships to fund the development and commercialization of AV-203 (CAN017) and ficlatuzumab, both clinical stage assets in oncology. The Company is currently seeking a partner to develop the AV-353 platform, a preclinical asset, worldwide for the potential treatment of pulmonary arterial hypertension. The Company previously partnered with Novartis International Pharmaceutical Ltd. (“Novartis”) to develop the AV-380 program in cachexia and other indications. Effective August 28, 2018, the Company expects to regain the rights to AV-380 and is considering a variety of options to continue the program’s development.
