– Analysis of TEAEs in TIVO-3 Study Shows Longer Time to Onset and Fewer Dose Reductions for TEAEs for Tivozanib Compared to Sorafenib –
– Data to be Presented at the 2021 ASCO Annual Meeting –
BOSTON–(BUSINESS WIRE)–AVEO Oncology (Nasdaq: AVEO), a commercial and clinical development stage biopharmaceutical company, today announced the presentation of additional data from the Phase 3 TIVO-3 study comparing FOTIVDAÂ® (tivozanib) to sorafenib in relapsed or refractory advanced renal cell carcinoma (RCC) following two or more prior systemic therapies. The data, which includes updated durability of response (DOR) and overall survival (OS) results, as well as an analysis of treatment-emergent adverse events (TEAEs) across study arms, will be featured in two poster presentations at the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting being held June 4-8 in a virtual setting. FOTIVDA, AVEOâ€™s oral, next-generation vascular endothelial growth factor (VEGF) tyrosine kinase inhibitor (TKI), is approved by the U.S. Food and Drug Administration for the treatment of adults with relapsed or refractory advanced RCC following two or more prior systemic therapies.
â€œWith advances in RCC treatment, patients are living longer, increasing the need for proven, well tolerated options in the relapsed or refractory setting,â€ said Brian Rini, MD, Chief of Clinical Trials at Vanderbilt Ingram Cancer Center and principal investigator of the TIVO-3 trial. â€œThe TIVO-3 study is the first positive Phase 3 study in RCC patients who received two or more prior systemic therapies, and these long-term follow up results continue to demonstrate the depth and durability of responses to FOTIVDA, as well as a tolerability profile that is particularly important in the later-stage treatment setting.â€
â€œFOTIVDA has demonstrated a differentiated clinical profile, and we are very pleased with initial receptivity to this differentiation and to the importance of the unique dataset that the TIVO-3 study represents in the commercial setting,â€ said Michael Bailey, president and chief executive officer of AVEO. â€œWe were also pleased to see efficacy advantages relative to sorafenib were maintained or improved with longer follow-up. We look forward to continuing to elucidate FOTIVDAâ€™s potential in the clinic, particularly in the immunotherapy combination setting, with patient enrollment in the pivotal Phase 3 TiNivo-2 study of FOTIVDA in combination with OPDIVOÂ® (nivolumab) anticipated to commence mid-year and execution of the Phase 2 hepatocellular carcinoma DEDUCTIVE trial in combination with IMFINZIÂ® (durvalumab) ongoing.â€
TIVO-3 ASCO Data
TIVO-3 is a Phase 3, open-label study that enrolled patients with metastatic RCC whose disease progressed on two or more prior systemic regimens, one of which included a VEGFR TKI. Patients were stratified by International Metastatic RCC Database Consortium (IMDC) risk category (favorable, intermediate, or poor) and type of prior therapy (two prior VEGFR TKIs, VEGFR TKI plus checkpoint inhibitor, VEGFR TKI plus any other systemic agent) then randomized 1:1 to receive tivozanib or sorafenib. Results from the study were published in Lancet Oncology (December 2019). Additional analyses and long-term follow up results from the TIVO-3 study to be presented at the 2021 ASCO Annual Meeting include:
- Durability of Response and Updated Overall Survival. Tivozanib demonstrated clinically meaningful and statistically significant improvements in overall response rate (ORR) and DOR compared to sorafenib in 350 patients randomized 1:1 with highly relapsed or refractory RCC. As of a January 15, 2021 data cutoff date, the median DOR for patients treated with tivozanib was 20.3 months (95% CI, 9.8-29.9 months) compared to 9.0 months (95% CI, 3.7-16.6 months) for patients treated with sorafenib. The ORR for patients treated with tivozanib was 23% compared to 11% for patients treated with sorafenib. Furthermore, long-term OS relative to sorafenib continues to improve (hazard ratio (HR): 0.91 [95% CI, 0.716-1.165; p=0.47]). The OS HR assesses the relative risk of death for the entirety of the data set.
- Temporal Characteristics of Treatment-Emergent Adverse Events and Dose Modifications. Patients in the TIVO-3 study had longer duration of treatment exposure with tivozanib than sorafenib (11.9 cycles vs. 6.7 cycles), but fewer all-grade and grade â‰¥3 TEAEs. TEAEs were generally similar with tivozanib and sorafenib. Time to dose modifications was longer with tivozanib than sorafenib. Among those with the same TEAEs, dose reductions, interruptions, or discontinuations were required more frequently with sorafenib than tivozanib.

About FOTIVDAÂ® (tivozanib)
FOTIVDAÂ® (tivozanib) is an oral, next-generation vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor (TKI). It is a potent, selective inhibitor of VEGFRs 1, 2, and 3 with a long half-life designed to improve efficacy and tolerability. AVEO received U.S. Food and Drug Administration (FDA) approval for FOTIVDA on March 10, 2021 for the treatment of adult patients with relapsed or refractory advanced renal cell carcinoma (RCC) following two or more prior systemic therapies. FOTIVDA was approved in August 2017 in the European Union and other countries in the territory of its partner EUSA Pharma (UK) Limited for the treatment of adult patients with advanced RCC. FOTIVDA has been shown to significantly reduce regulatory T-cell production in preclinical models.1 FOTIVDA was discovered by Kyowa Kirin.
FOTIVDA is indicated for the treatment of adult patients with relapsed or refractory advanced renal cell carcinoma (RCC) following two or more prior systemic therapies.

About Advanced Renal Cell Carcinoma
According to the American Cancer Societyâ€™s 2021 statistics, renal cell carcinoma (RCC) is the most common type of kidney cancer, which is among the ten most common cancers in both men and women. Approximately 73,750 new cases of kidney cancer will be diagnosed annually and about 14,830 people will die from this disease. In patients with late-stage disease, the five-year survival rate is 13%. Agents that target the vascular endothelial growth factor (VEGF) pathway have shown significant antitumor activity in RCC.2 According to a 2019 publication, 50% of the approximately 10,000 patients who progress following two or more lines of therapy choose not to receive further treatment,3 which may be attributable to tolerability concerns and a lack of data to support evidence-based treatment decisions in this highly relapsed or refractory patient population.
