BOSTON--(BUSINESS WIRE) March 10, 2021 -- AVEO Oncology (Nasdaq: AVEO) today announced that the U.S. Food and Drug Administration (FDA) has approved Fotivda (tivozanib) for the treatment of adults with relapsed or refractory advanced renal cell carcinoma (RCC) who have received two or more prior systemic therapies. Fotivda is an oral, next-generation vascular endothelial growth factor (VEGF) tyrosine kinase inhibitor (TKI).

“Today’s approval of Fotivda provides a new tool for treating patients with kidney cancer who have relapsed or become refractory to two or more prior systemic therapies,” said Brian Rini, MD, Chief of Clinical Trials at Vanderbilt Ingram Cancer Center and principal investigator of the TIVO-3 trial. “With advances in RCC treatment, patients are living longer, increasing the need for proven, well tolerated treatment options in the relapsed or refractory setting. The TIVO-3 study is the first positive Phase 3 study in RCC patients who received two or more prior systemic therapies, and also the first Phase 3 RCC study to include a predefined population of patients who have received prior immunotherapy, the current standard of care in earlier-line treatment. With this approval, I believe Fotivda represents an attractive intervention, and expect it to play a meaningful role in the evolving RCC treatment landscape.”

“We believe in Fotivda’s potential to provide a differentiated treatment option for the growing number of individuals in the U.S. with relapsed or refractory RCC, and today marks the culmination of many years of hard work and determination of many individuals to bring this therapy to patients,” said Michael Bailey, president and chief executive officer of AVEO. “With today’s approval, AVEO begins its journey as a commercial-stage company, a noteworthy accomplishment in our industry. On behalf of the entire AVEO team, I would like to thank all the patients, their families, and caregivers whose tireless efforts made this day possible.”

“Relapsed or refractory RCC is a devastating disease for which patient outcomes can be limited due to the tradeoff between tolerability and efficacy,” said Dena Battle, president of KCCure. “The FDA approval of Fotivda represents an exciting, meaningful advancement by providing a new treatment option for this patient population.”

AVEO plans to make Fotivda available to patients in the U.S. by March 31, 2021.

The approval of Fotivda is based on AVEO’s pivotal Phase 3 study, TIVO-3, comparing Fotivda to sorafenib in relapsed or refractory advanced RCC following two or more prior systemic therapies. The application is also supported by three additional trials in RCC and includes safety data from over 1,000 clinical trial subjects.

Patients (n=350) enrolled in the TIVO-3 study were randomized 1:1 to receive either Fotivda or sorafenib. The main efficacy outcome measure was progression-free survival (PFS), assessed by a blinded independent radiology review committee. Other efficacy endpoints were overall survival (OS) and objective response rate (ORR).

Median PFS was 5.6 months (95% CI: 4.8, 7.3) in the Fotivda arm (n=175) compared with 3.9 months (95% CI: 3.7, 5.6) for those treated with sorafenib (HR 0.73; 95% CI: 0.56, 0.95; p=0.016). Median OS was 16.4 (95% CI: 13.4, 21.9) and 19.2 months (95% CI: 14.9, 24.2), for the Fotivda and sorafenib arms, respectively (HR 0.97; 95% CI: 0.75, 1.24). The ORR was 18% (95% CI: 12%, 24%) for the Fotivda arm and 8% (95% CI: 4%, 13%) for the sorafenib arm.

The most common (≥20%) adverse reactions were fatigue, hypertension, diarrhea, decreased appetite, nausea, dysphonia, hypothyroidism, cough, and stomatitis. The most common grade 3 or 4 laboratory abnormalities (≥5%) were decreased sodium, increased lipase, and decreased phosphate.

The recommended tivozanib dose is 1.34 mg once daily with or without food for 21 days every 28 days on treatment followed by 7 days off treatment (28 day cycle) until disease progression or unacceptable toxicity.

About Fotivda (tivozanib)

Fotivda (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 models1. Fotivda was discovered by Kyowa Kirin.

INDICATIONS

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.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Hypertension and Hypertensive Crisis: Control blood pressure prior to initiating Fotivda. Monitor for hypertension and treat as needed. For persistent hypertension despite use of anti-hypertensive medications, reduce the Fotivda dose.

Cardiac Failure: Monitor for signs or symptoms of cardiac failure throughout treatment with Fotivda.

Cardiac Ischemia and Arterial Thromboembolic Events: Closely monitor patients who are at increased risk for these events. Permanently discontinue Fotivda for severe arterial thromboembolic events, such as myocardial infarction and stroke.

Venous Thromboembolic Events: Closely monitor patients who are at increased risk for these events. Permanently discontinue Fotivda for severe venous thromboembolic events.

Hemorrhagic Events: Closely monitor patients who are at risk for or who have a history of bleeding.

Proteinuria: Monitor throughout treatment with Fotivda. For moderate to severe proteinuria, reduce the dose or temporarily interrupt treatment with Fotivda.

Thyroid Dysfunction: Monitor before initiation and throughout treatment with Fotivda.

Risk of Impaired Wound Healing: Withhold Fotivda for at least 24 days before elective surgery. Do not administer for at least 2 weeks following major surgery and adequate wound healing. The safety of resumption of Fotivda after resolution of wound healing complications has not been established.

Reversible Posterior Leukoencephalopathy Syndrome (RPLS): Discontinue Fotivda if signs or symptoms of RPLS occur.

Embryo-Fetal Toxicity: Can cause fetal harm. Advise patients of the potential risk to a fetus and to use effective contraception.

Allergic Reactions to Tartrazine: The 0.89 mg capsule of Fotivda contains FD&C Yellow No.5 (tartrazine) which may cause allergic-type reactions (including bronchial asthma) in certain susceptible patients.

ADVERSE REACTIONS

The most common (≥20%) adverse reactions were fatigue, hypertension, diarrhea, decreased appetite, nausea, dysphonia, hypothyroidism, cough, and stomatitis, and the most common Grade 3 or 4 laboratory abnormalities (≥5%) were sodium decreased, lipase increased, and phosphate decreased.

DRUG INTERACTIONS

Strong CYP3A4 Inducers: Avoid coadministration of Fotivda with strong CYP3A4 inducers.

USE IN SPECIFIC POPULATIONS

Lactation: Advise not to breastfeed.
Females and Males of Reproductive Potential: Can impair fertility.

About Advanced Renal Cell Carcinoma

According to the American Cancer Society’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.
