   • Myocardial infarction, severe angina, or unstable angina within 6 months prior to administration of first dose of study drug.
   • History of serious ventricular arrhythmia (ie, ventricular tachycardia or ventricular fibrillation)
   • Cardiac arrhythmias requiring anti-arrhythmic medications (except for atrial fibrillation that is well controlled with anti-arrhythmic medication)
   • Coronary or peripheral artery bypass graft within 6 months of screening
7. Non-healing wound, bone fracture, or skin ulcer.
8. Active peptic ulcer disease, inflammatory bowel disease, ulcerative colitis, or other gastrointestinal condition with increased risk of perforation; history of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 4 weeks prior to administration of first dose of study drug
9. Serious/active infection or infection requiring parenteral antibiotics.
10. Inadequate recovery from any prior surgical procedure or major surgical procedure within 4 weeks prior to administration of first dose of study drug.

11. Significant thromboembolic or vascular disorders within 6 months prior to administration of first dose of study drug, including but not limited to:

    • Deep vein thrombosis
    • Pulmonary embolism
    • Cerebrovascular accident (CVA) or transient ischemic attack (TIA)

13. Currently active second primary malignancy, including hematologic malignancies (leukemia, lymphoma, multiple myeloma, etc.), other than non-melanoma skin cancers, non-metastatic prostate cancer, in situ cervical cancer, and ductal or lobular carcinoma in situ of the breast. Subjects are not considered to have a currently active malignancy if they have completed anti-cancer therapy and have been disease free for >2 years.
14. Pregnant or lactating females.
15. History of genetic or acquired immune suppression disease such as HIV; subjects on immune suppressive therapy for organ transplant.
16. Life-threatening illness or organ system dysfunction compromising safety evaluation.
17. Requirement for hemodialysis or peritoneal dialysis.
18. Inability to swallow pills, malabsorption syndrome or gastrointestinal disease that severely affects the absorption of tivozanib, major resection of the stomach or small bowel, or gastric bypass procedure.
19. Psychiatric disorder or altered mental status precluding informed consent or protocol-related testing.

20. Sexually active pre-menopausal female subjects (and female partners of male subjects) must use adequate contraceptive measures, while on study and for 30 days after the last dose of study drug. All fertile male and female subjects must agree to use a highly effective method of contraception (including their partner). Effective birth control includes:
