news: * On June 11, 2015, Aveo Oncology announced that it has received written feedback from the FDA regarding a potential pivotal study for tivozanib in the treatment of NRP-1 low colorectal cancer (CRC). Aveo recently presented results from the BATON-CRC study, a 265 patient randomized trial exploring the combination of mFOLFOX6 and tivozanib or bevacizumab as first-line treatment in patients with advanced metastatic CRC, at the 2015 American Association for Cancer Research (AACR) Tumor Angiogenesis and Vascular Normalization Conference. Among the predefined biomarkers explored in this study, neuropilin-1 (NRP-1), a signaling protein known to bind to VEGF-A in serum, was found to be a potential prognostic marker for angiogenesis inhibitor activity and may be predictive of tivozanib activity relative to bevacizumab. Results from this study and the Company’s ongoing assay development efforts were presented to the FDA. Updated analyses from the Company’s assay development efforts, which are similar to those presented at the AACR conference, will be presented at the upcoming European Society of Medical Oncology 17th World Congress on Gastrointestinal Cancer taking place July 1-4, 2015 in Barcelona Spain. In response to questions from Aveo regarding a proposed pivotal phase 3 trial of tivozanib in CRC, the FDA suggested that the Company continue work on the development of its biomarker assay to address variability between assays presented, and that, at present, “insufficient data exists to determine the appropriateness of this [NRP-1 low] subgroup” for the proposed phase 3 study. This feedback is consistent with the Company’s current clinical strategy and discussions with cancer research cooperative groups. As such, Aveo plans to evaluate options to confirm the activity of tivozanib and FOLFOX in NRP-1 low CRC through a prospectively defined, randomized Phase 2 study, while continuing to work on the development of a commercially viable assay.
