Full prescribing information available at www.FOTIVDA.com FOTIVDA® (tivozanib) FOTIVDA (tivozanib) is an oral, vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor indicated for the treatment of adult patients with relapsed or refractory (R/R) advanced renal cell carcinoma (RCC) following two or more prior systemic therapies. 5 FOTIVDA is the First Therapy Approved for Adults with R/R Advanced RCC Following Two or More Prior Systemic Therapies TIVO-3 is the First Phase 3 Study in RCC that Included a Predefined Population of Patients Who Received Prior Immunotherapy NCCN: Recommended for Subsequent Therapy* * NCCN Guidelines; Updated 3/23/2021; For patients who received 2 or more prior systemic therapies; NCCN makes no warranties of any kind whatsoever regarding their content, use or application and disclaims any responsibility for their application or use in any way.

FOTIVDA: A Uniquely Positioned VEGF-TKI • Potent, selective, long half-life inhibitor of all three VEGF receptors that is designed to optimize VEGF blockade while minimizing off-target toxicities • TIVO-3: Superior disease control (PFS, ORR & DoR) vs. sorafenib • Fewer dose reductions, interruptions and discontinuations due to AEs compared to sorafenib • Most frequent Grade 3/4 adverse event is hypertension • RCC monotherapy clinical trial safety data >1,000 patients • Ongoing development path in combination with immunotherapy and HIF2α • FOTIVDA significantly reduces Tregs potentially enhancing immuno-oncologic effect • Selective profile with low off-target toxicities beneficial in combination PFS = Progression Free Survival ORR = Over Response Rate DoR = Duration of Response

7 ASCO GU 2022 – 5 Year Efficacy Update* 3 Year 12% vs 2% 4 Year 8% vs 0% Five year follow-up data show FOTIVDA® (tivozanib) patients were up to 5X more likely to experience long-term PFS compared to Nexavar® (sorafenib) Long-term data from pivotal TIVO-3 study demonstrate durable disease control and a non-significant trend for overall survival favoring FOTIVDA® (tivozanib) (HR 0.89) * Exploratory Investigator-assessed PFS analysis upon extended follow-up was consistent with the independent review committee (IRC) PFS analysis, which was the primary endpoint for TIVO-3.

Eur Urol (2016) *Internal Awareness Trial and Usage (ATU) Survey (May 2020) Third-line Targeted Therapy in Metastatic Renal Cell Carcinoma: Results from the International Metastatic Renal Cell Carcinoma Database Consortium Background: The use of third-line targeted therapy (TTT) in metastatic renal cell carcinoma (mRCC) is not well characterized and varies due to the lack of robust data to guide treatment decisions. This study examined the use of third-line therapy in a large international population. In the 3rd line anything can go if the patient can tolerate the treatment. This is not a well-studied population and combos like Lenvima and Afinitor seem to have a good response but have high toxicity. Only half of patients are willing to be challenged with treatment and the other half go to hospice.” Academic ONC.* Only about 30% get to the 3rd line because of their performance status.

Cachexia, Sarcopenia and Muscle 2010 + AVEO data on file Cachexia is a muscle wasting disease commonly associated with cancer • ~50% of people with cancer will suffer from cachexia* • ~30% of all cancer patients die from cachexia* GDF15 is a key driver in cancer cachexia • GDF15 is elevated in cachexia • Expression of GDF15 induces cachexia • Inhibition of GDF15 reverses cachexia in animal models • Managing cachexia has the potential to improve OS + +
