Eligibility criteria:
Inclusion Criteria:

The subject must have participated on Protocol AV-951-09-301, and must meet either of the following bulleted criteria:

Demonstrated disease progression per RECIST during treatment with sorafenib, OR
Demonstrated clinical benefit [complete response (CR), partial response (PR), or stable disease (SD) per RECIST] and acceptable tolerability after treatment with tivozanib or sorafenib on protocol AV-951-09-301.
Eastern Cooperative Oncology Group performance status ≤ 2 and life expectancy ≥ 3 months.
If female and of childbearing potential, documentation of negative pregnancy test prior to enrollment.
Ability to give written informed consent

Exclusion Criteria:

Newly identified central nervous system (CNS) malignancies or documented progression of CNS metastases; subjects will be allowed only if the CNS metastases have been adequately treated with radiotherapy or surgery. For subjects receiving steroid therapy for allowed steroid maintenance therapy.

Duration since last dose on Protocol AV-951-09-301:

For subjects continuing tivozanib or sorafenib (subjects who demonstrated clinical benefit and acceptable tolerability during treatment with tivozanib or sorafenib on protocol AV-951-09-301): more than 2 weeks since last dose of tivozanib or sorafenib.
For subjects initiating tivozanib (ie demonstrated disease progression during treatment with sorafenib): more than 4 weeks since last dose of sorafenib. Subjects demonstrating disease progression due to CNS metastasis will be allowed up to 8 weeks since last dose of sorafenib in order to complete treatment for CNS metastasis.
Inadequate recovery from any prior surgical procedure or major surgical procedure within 4 weeks prior to administration of first dose of study drug.

Any of the following hematologic abnormalities:

Hemoglobin < 9.0 g/dL
Absolute neutrophil count < 1500 per mm3
Platelet count < 75,000 per mm3
Prothrombin time or Partial thromboplastin time >1.5 × upper limit of normal (ULN)

Any of the following serum chemistry abnormalities:

Total bilirubin > 1.5 × ULN (or > 2.5 × ULN for subjects with Gilbert's syndrome)
Aspartate aminotransferase or alanine aminotransferase > 2.5 × ULN (or > 5 × ULN for subjects with liver metastasis)
Alkaline phosphatase > 2.5 × ULN (or > 5 × ULN for subjects with liver or bone metastasis)
Creatinine > 2.0 × ULN
Proteinuria > 3+ by urinalysis or urine dipstick
If female, pregnant or lactating.
Sexually active pre-menopausal female subjects (and female partners of male subjects) must use adequate contraceptive measures, while on study and for at least 50 days after the last dose of study drug. Sexually active male subjects must use adequate contraceptive measures, while on study and for at least 90 days after the last dose of study drug. All fertile male and female subjects,and their partners,must agree to use a highly effective method of contraception. Effective birth control includes (a) Intrauterine device plus one barrier method; or (b) 2 barrier methods. Effective barrier methods are male or female condoms, diaphragms, and spermicides (creams or gels that contain a chemical to kill sperm). (Note: Oral, implantable, or injectable contraceptives may be affected by cytochrome P450 interactions, and are not considered effective for this study).

Unhealed wounds (including active peptic ulcers).
Serious/active infection or infection requiring parenteral antibiotics.
Life-threatening illness or organ system dysfunction compromising safety evaluation.
Psychiatric disorder, altered mental status precluding informed consent or necessary testing.
Inability to comply with protocol requirements.
Treatment with another anti-cancer therapy or participation in another interventional protocol (excluding AV-951-09-301).
