AVEO Oncology Announces Results from Phase 1b Portion of DEDUCTIVE Study of Tivozanib (FOTIVDA®) in Combination with IMFINZI® (durvalumab) in Previously Untreated Metastatic Hepatocellular Carcinoma
AVEO Oncology (Nasdaq: AVEO) announced results from the Phase 1b portion of the DEDUCTIVE clinical trial for tivozanib (FOTIVDA®), combined with AstraZeneca's IMFINZI®, in advanced hepatocellular carcinoma (HCC). In seven patients, the combination exhibited a 29% partial response rate and a 71% disease control rate, with no dose-limiting toxicities reported. The Phase 2 portion is expected to enroll 30 additional subjects later this year. AVEO continues to pursue regulatory approval for tivozanib in relapsed or refractory renal cell carcinoma (RCC).
- 29% partial response rate and 71% disease control rate in Phase 1b trial.
- No dose-limiting toxicities observed, demonstrating tolerability.
- Ongoing Phase 2 trial expected to enroll an additional 30 patients.
- Limited sample size of seven patients may affect result reliability.
- Dependence on successful regulatory approval for RCC affects future growth.
AVEO Oncology (Nasdaq: AVEO) today announced the presentation of results from the Phase 1b portion of the Phase 1b/2 DEDUCTIVE clinical trial of tivozanib (FOTIVDA®), AVEO’s vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor (TKI) drug candidate, in combination with IMFINZI® (durvalumab), AstraZeneca’s (LSE/STO/Nasdaq: AZN) human monoclonal antibody directed against programmed death-ligand 1 (PD-L1), in patients with advanced or metastatic hepatocellular carcinoma (HCC). The results are being presented today in a poster session at the 2021 American Society of Clinical Oncology Gastrointestinal (ASCO GI) Cancers Symposium being held virtually.
A total of seven patients with advanced or metastatic HCC were enrolled in the Phase 1b portion of the study, which was designed to determine the recommended Phase 2 dose and assess preliminary safety and efficacy of the tivozanib/durvalumab combination. Patients received 1.0 mg of tivozanib for 21 days followed by 7 days off therapy combined with 1500 mg of durvalumab every 28 days. The combination was well tolerated, with no dose-limiting toxicities. The combination demonstrated a

“We believe that data observed in the Phase 1b portion of the DEDUCTIVE study continue to support tivozanib’s potential to serve as an attractive VEGFR TKI to use in the immunotherapy combination setting,” said Michael Bailey, president and chief executive officer of AVEO. “As we await a decision on our New Drug Application for single agent tivozanib in relapsed or refractory renal cell carcinoma (RCC), we remain focused on executing on our combination strategy, including in metastatic RCC and HCC.”
About Tivozanib (FOTIVDA®)
Tivozanib is an oral, once-daily, next-generation VEGFR TKI discovered by Kyowa Kirin Co. and approved as FOTIVDA® for the treatment of adult patients with advanced RCC in the European Union and other countries in the territory of the Company’s partner, EUSA Pharma (UK) Limited (EUSA territory). 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 adult patients with relapsed or refractory advanced 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 RCC.4 Tivozanib has been investigated in several tumor types, including renal cell, hepatocellular, colorectal, ovarian and breast cancers. Tivozanib is also being studied by partner Kyowa Kirin Co. in non-oncology indications.
