On March 31, 2020 AVEO Oncology (NASDAQ: AVEO) reported that it has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for tivozanib, the Company’s vascular endothelial growth factor receptor tyrosine kinase inhibitor (VEGFR-TKI), as a treatment for relapsed or refractory renal cell carcinoma (RCC) (Press release, AVEO, MAR 31, 2020, View Source [SID1234556051]).

"NDA submission is a distinguishing milestone for any development stage biotechnology company, and our tivozanib NDA is an important step in our goal of providing an effective and more tolerable therapeutic option to patients with relapsed or refractory RCC," said Michael Bailey, president and chief executive officer. "The TIVO-3 study provides valuable insight into the potential sequencing of therapy following earlier TKI and immunotherapy treatment, an area of significant need for kidney cancer patients whose disease has relapsed or become refractory to multiple lines of therapy. All of us at AVEO offer our continued gratitude to the patients, caregivers, and investigators who participated in our clinical trials. We look forward to working closely with the FDA during their review process and remain hopeful that the study’s overall survival (OS) hazard ratio (HR) will continue to favor tivozanib at the time of the final readout, expected by June 2020."
The NDA submission is based on the pivotal active comparator-controlled Phase 3 study, TIVO-3, comparing tivozanib to sorafenib in 3rd and 4th line RCC patients. The application is supported by three additional trials, including an active comparator-controlled supportive Phase 3 study, TIVO-1, comparing tivozanib to sorafenib, and two Phase 2 studies, Study 902, the open-label, crossover clinical study of tivozanib for patients who progressed on sorafenib in TIVO-1, as well as placebo-controlled Study 201 in first line RCC patients.
A final OS analysis of the TIVO-3 study will be conducted in the second quarter based on a May 1, 2020 data cutoff date. AVEO expects to report results from the final OS analysis by June 2020. The FDA and the Company agreed that if, during the review, the final analysis yields an OS HR above 1.00, the Company will withdraw its NDA.
About Tivozanib (FOTIVDA)
Tivozanib (FOTIVDA) is an oral, once-daily, vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor (TKI) discovered by Kyowa Kirin and approved for the treatment of adult patients with advanced renal cell carcinoma (RCC) in the European Union, the United Kingdom, Norway, New Zealand 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 is being studied in the TIVO-3 trial, which is supporting a regulatory submission of tivozanib in the U.S. seeking marketing approval as a treatment for relapsed/refractory RCC. 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 RCC4. Tivozanib has been investigated in several tumor types, including renal cell, hepatocellular, colorectal, ovarian and breast cancers.
