AVEO Oncology Announces Immuno-Oncology Clinical Collaboration with AstraZeneca

Phase 1/2 Study will Evaluate Combination of IMFINZI® (durvalumab) and FOTIVDA® (tivozanib) in First-Line HCC

CAMBRIDGE, Mass.--()--AVEO Oncology (NASDAQ: AVEO) today announced that it has entered into a clinical collaboration with AstraZeneca to evaluate the safety and efficacy of AstraZeneca's IMFINZI® (durvalumab), a human monoclonal antibody directed against programmed death-ligand 1 (PD-L1), in combination with FOTIVDA® (tivozanib), AVEO’s oral, once-daily, potent and highly-selective vascular endothelial growth factor receptor tyrosine kinase inhibitor (VEGFR-TKI) in first-line hepatocellular carcinoma (HCC), or liver cancer, in a Phase 1/2 study.

AVEO will serve as the study sponsor, with study costs shared equally by both parties and clinical drug supplied by each respective company. The Phase 1 portion of the study is expected to commence in 2019.

“We are thrilled to collaborate with AstraZeneca to explore another tivozanib-immunotherapy combination and look forward to understanding the potential of combining tivozanib with durvalumab in liver cancer,” said Michael Bailey, president and chief executive officer of AVEO. “TKI-immunotherapy combinations have demonstrated important clinical potential across multiple tumor types, though toxicities associated with these combinations have limited their potential use. Our goal is to establish tivozanib as the TKI of choice for use with immunotherapies by demonstrating efficacy with reduced toxicity.”

About Tivozanib (FOTIVDA®)

Tivozanib (FOTIVDA®) is an oral, once-daily, vascular endothelial growth factor (VEGF) tyrosine kinase inhibitor (TKI) discovered by Kyowa Hakko Kirin and approved for the treatment of adult patients with advanced renal cell carcinoma (RCC) in the European Union plus Norway and Iceland. It is a potent, selective and long half-life inhibitor of all three VEGF receptors and is designed to optimize VEGF blockade while minimizing off-target toxicities, potentially resulting in improved efficacy and minimal dose modifications.1,2 Tivozanib has been shown to significantly reduce regulatory T-cell production in preclinical models3, and has demonstrated synergy in combination with nivolumab (anti PD-1) in a Phase 2 study in RCC. Tivozanib has been investigated in several tumors types, including renal cell, hepatocellular, colorectal and breast cancers.

About Durvalumab (IMFINZI®)

Durvalumab (IMFINZI®) is a human monoclonal antibody that binds to PD-L1 and blocks the interaction of PD-L1 with PD-1 and CD80, countering the tumor's immune-evading tactics and releasing the inhibition of immune responses. As part of a broad development program, durvalumab is being investigated as monotherapy and in combination with immuno-oncology (IO) agents, small molecules, and chemotherapies across a range of tumors and stages of disease.

About AVEO

AVEO Pharmaceuticals, Inc. (the “Company” or “AVEO”) 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 or metastatic renal cell carcinoma (“RCC”). The Company has outlicensed tivozanib (FOTIVDA®) for oncological indications 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 RCC 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 RCC. The Company has entered into partnerships for 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 and oncology. In addition, a new formulation of tivozanib is being explored in ocular conditions. The Company has recently regained the rights to its AV-380 program for the potential treatment of cachexia and is considering a variety of options to advance the program’s development.
