Announce Expected Initiation of an Investigator-Initiated, Randomized, Phase 2, Multicenter Trial of Ficlatuzumab and Cetuximab in HNSCC in 2H 2017
AVEO Announces Trial in Progress Poster Also Presented Highlighting Phase 3 TIVO-3 Study of Tivozanib in RCC
CAMBRIDGE, MA, USA I June 5, 2017 I AVEO Oncology (NASDAQ: AVEO) and Biodesix, Inc., co-development partners, today announced the presentation of results from two investigator-sponsored Phase 1 studies of ficlatuzumab at the 2017 American Society of Clinical Oncology (ASCO) Annual Meeting taking place in Chicago, Illinois. The first is a study of ficlatuzumab in combination with the EGFR inhibitor cetuximab in patients with cetuximab-resistant, metastatic head and neck squamous cell carcinoma (HNSCC), and the second is a study of ficlatuzumab in combination with high-dose cytarabine in patients with high risk relapsed or refractory acute myeloid leukemia (AML). Ficlatuzumab is a humanized IgG1 antibody that binds to the HGF ligand with high affinity and specificity to inhibit the biological activities of the HGF/c-Met pathway.
“HGF is an important pathway for resistance and proliferation in a number of cancer models, serving as a means to overcome EGFR inhibition in HNSCC, and as an adverse prognostic factor in AML,” said Michael Needle, chief medical officer of AVEO. “In a Phase 1 study in patients with cetuximab-resistant recurrent/metastatic HNSCC, the addition of ficlatuzumab to the EGFR-targeted antibody cetuximab resulted in a disease control rate of 67%, and prolonged progression free and overall survival compared to historical controls, in addition to being well tolerated. With continued, strong investigator support, we look forward to the expected initiation, in the second half of 2017, of a randomized, Phase 2, multicenter, investigator-initiated trial to confirm these findings. We also look forward to the completion of the ongoing investigator-sponsored study in AML, which has demonstrated early signs of tolerability and activity, including a 50% complete response rate in the relapsed/refractory setting.”
“Median PFS for cetuximab monotherapy in the naïve setting is only two months, as with the median PFS for nivolumab or single-agent chemotherapy in the platinum-refractory setting, suggesting an urgent need for new therapies,” said Julie E. Bauman, MD, MPH, Professor of Medicine, Chief, Division of Hematology/Oncology, Associate Director of Translational Research, University of Arizona Cancer Center. “Although a small cohort, the fact that we observed significant responses and PFS of 6 months in a refractory population in this study suggests important biologic activity.”
AVEO also announced that a Trials in Progress presentation highlighting the ongoing Phase 3, randomized, controlled, multi-center, open-label TIVO-3 study comparing tivozanib, the Company’s potent, selective, long half-life inhibitor of all three vascular endothelial growth factor (VEGF) receptors, to sorafenib in subjects with refractory advanced renal cell carcinoma.

Phase I study of the anti-HGF mononclonal antibody (mAb), ficlatuzumab, and cetuximab in cetuximab-resistant, recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC)
Presenter: Julie E. Bauman, MD, MPH, Chief, Division of Hematology and Oncology, Associate Director, Translational Research, University of Arizona Cancer Center
Abstract Number: 6038
Session: Head and Neck Cancer
Date and Time: Monday, June 5, 2017, 1:15-4:45 PM CT
In this phase I study, 12 patients with R/M HNSCC who had disease recurrence within 6 months of cetuximab radiation or progression within 6 months of cetuximab treatment in the recurrent metastatic setting were treated with a ficlatuzumab/cetuximab combination. The primary objective was to establish the recommended Phase 2 dose (RP2D) for ficlatuzumab, with the secondary objectives being to evaluate preliminary clinical efficacy of RP2D and to evaluate the relationship between preliminary efficacy and 1) baseline tumor p-Met expression and 2) serum Veristrat.
Cetuximab was administered every 2 weeks at 500 mg/m2, and ficlatuzumab dose tiers were 10 mg/kg (tier 1) or 20 mg/kg IV every 2 weeks (tier 2), with inter-patient escalation or de-escalation based on cumulative dose-limiting toxicities (DLT). RP2D was set at tier 2 if no DLTs were observed after 8 enrolled patients, with expansion continuing to 12 patients. Three patients were treated at dose tier 1 and 9 at dose tier 2. The RP2D is ficlatuzumab 20 mg/kg and cetuximab 500 mg/m2 every 2 weeks. The overall response rate was 17% (1 PR at tier 1; 1 at tier 2) and 50% of patients had stable disease, for a disease control rate of 67%. Median PFS and OS at RP2D were 6.0 mos (90% CI=2 mos-NR) and 8.2 mos (90% CI=2.7 mos-NR).
CyFi: A phase I study exploring the role of cMET pathway inhibition with ficlatuzumab (Fi) combined with high-dose cytarabine (Cy) in patients with high risk relapsed or refractory acute myeloid leukemia (AML)
Presenter: Charalambos (Babid) Andreadis, MD, Hematologic Malignancies and Blood and Marrow Transplantation Program, University of California, San Francisco
Abstract Number: 7040
Session: Hematologic Malignancies – Leukemia, Myelodyplastic Syndromes, and Allotransplant
Date and Time: Monday, June 5, 2017, 8:00-11:30 AM CT
In this ongoing study, the safety and tolerability of ficlatuzumab in combination with cytarabine was assessed in 9 patients with high risk relapsed or refractory acute myeloid leukemia. Ficlatuzumab was given in escalated dosing of 10, 15, or 20 mg/kg for 4 doses every 2 weeks, starting on day 0, and cytarabine was given at a fixed dose of 2g/m2 on days 2-7, using a 3×3 design. Dose-limiting toxicity (DLT) was defined based on toxicities attributable to the combination and unexpected with AML or high-dose cytarabine. Peripheral blood mononuclear cells and serum were collected at defined time points to assess HGF levels and activation of the c-Met pathway. The results showed no DLTs, and the combination has proven well tolerated. The most frequent grade 3-4 adverse events were febrile neutropenia (56%), ventricular tachycardia (22%), respiratory distress (11%), electrolyte disturbance (11%). There was 1 death from sepsis and multi-organ failure on day 23, during count recovery. Of the 8 evaluable patients, 4 achieved a CR (50%), all in the 2nd dose cohort. All patients had detectable circulating HGF levels at baseline and levels increased following exposure to Fi by an average of 193% (p value). Baseline levels or change from baseline were not associated with response.
