Tivozanib (see structure, AV-951) is an oral VEGF receptor tyrosine kinase inhibitor. It is undergoing clinical trial investigation for the treatment of renal cell carinomas. An oral quinoline urea derivative, tivozanib suppresses angiogenesis by being selectively inhibitory against vascular endothelial growth factor.
The positive results of this Phase 2 trial informed the design and
implementation of TIVO-1, a pivotal Phase 3 clinical study in advanced
RCC demonstrating tivozanib superiority over sorafenib in the primary
endpoint of PFS in the first-line setting, top-line data from which were
reported in January 2012.
“Current RCC therapies are associated with toxicities that can interfere with patients’ treatment regimens and impact treatment efficacy and activities of daily living,” said Dmitry A. Nosov, M.D., Ph.D., senior clinical researcher at the Blokhin Oncology Research Center, Moscow, Russian Federation, lead author of the Phase 2 study and TIVO-1 investigator.
“Despite recent progress in treating patients with RCC, patients and physicians would benefit from a new RCC treatment option that delivers both improved efficacy and a more tolerable safety profile. The combined tivozanib efficacy and safety data demonstrated in this Phase 2 study supports tivozanib as a potential advancement in the RCC treatment landscape.”
Based on the positive Phase 2 data and success of the TIVO-1 trial, AVEO and its collaborator Astellas Pharma Inc. are moving forward with plans for submitting the tivozanib NDA in RCC in the third quarter of 2012, with the MAA submission to follow.
“We believe that the efficacy and safety profile consistently demonstrated by tivozanib and recently validated in our Phase 3 TIVO-1 trial represent an important step forward in the treatment of patients who have advanced RCC,” said William Slichenmyer, M.D., Sc.M., chief medical officer, AVEO. “We are pleased with the opportunity to collaborate with tivozanib study investigators on publishing these positive Phase 2 data in the Journal of Clinical Oncology, and look forward to advancing our work with our global partners at Astellas to bring tivozanib to patients who can benefit from this therapy.”....
