A Notice of Allowance is issued after the USPTO decides that a patent can be granted from a patent application. The majority of patent applications that receive a Notice of Allowance will issue as a U.S. patent once the issue fee is paid. However, a Notice of Allowance is not a guarantee of patent issuance.

"We are pleased by the progress we have made at the United States Patent and Trademark Office and the continued recognition of FOTIVDA to treat refractory advanced RCC in subjects who have received at least two prior anti-cancer therapies," said Michael Bailey, AVEO’s president and chief executive officer. "When issued, this patent is expected to provide a potential barrier for generic entry. It is part of our broader life cycle management strategy and is designed to extend the commercial opportunity of FOTIVDA, following a long development path and a relatively short exclusivity period since FOTIVDA’s approval by the U.S. Food and Drug Administration in March 2021."

If issued, AVEO plans to list this patent in the United States Food and Drug Administration’s Orange Book: Approved Drug Products with Therapeutic Equivalence Evaluations as it relates to FOTIVDA with an expiration date of November 5, 2039.

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 models.2 FOTIVDA was discovered by Kyowa Kirin.

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.3 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,4 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.
