Brief summary: The purpose of this study is to test the safety and tolerability of tivozanib (AV-951) and Torisel™ given in combination for renal cell cancer. The study will also assess the effects of the combination of tivozanib (AV-951) and Torisel™ on the tumor. Tivozanib (AV-951) is a VEGF-receptor tyrosine kinase inhibitor, and may stop the growth of tumor cells by blocking blood flow to the tumor. Temsirolimus is an mTOR inhibitor which is approved for the treatment of advanced renal cell carcinoma.

Detailed description: This is a Phase 1b, open-label, dose-finding study of tivozanib (AV-951) in combination with temsirolimus to include approximately 36 subjects with metastatic renal cell carcinoma (mRCC). This study is designed to evaluate the safety, tolerability, dose-limiting toxicities (DLT), maximum tolerated dose (MTD), pharmacokinetic, pharmacogenomic, and antineoplastic activity of tivozanib (AV-951) when administered in combination with temsirolimus. Tivozanib (AV-951) will be administered once daily for 3 weeks beginning on Day 1 of Cycle 1, followed by 1 week off (1 cycle = 4 weeks). Temsirolimus will be administered intravenously once weekly starting on Day 8 of Cycle 1.

Eligibility criteria: Inclusion Criteria:

* ≥ 18-year-old males or females
* Histologically confirmed renal cell carcinoma with a clear cell component
* Documented progressive disease
* Measurable disease by RECIST criteria
* No more than 1 prior VEGF receptor targeted therapy; no prior treatment with temsirolimus or other drugs targeting the mTOR pathway
* Karnofsky performance status \> 70%; life expectancy ≥ 3 months
* Ability to give written informed consent

Exclusion Criteria:

  * Active clinically symptomatic left ventricular failure
  * Active hypertension (diastolic blood pressure \> 100 mmHg). Subjects with a history of hypertension must have been on stable doses of anti-hypertensive drugs for ≥ 4 weeks
  * Uncontrolled hypertension: Blood pressure \>140/90 mmHg on 2 or more antihypertensive medications
  * Myocardial infarction within 3 months prior to administration of first dose of study drug

* Ongoing hemoptysis or history of clinically significant bleeding
* Cerebrovascular accident within 12 months of study entry, or peripheral vascular disease with claudication on walking less than 1 block
* Deep venous thrombosis or pulmonary embolus within 6 months of study entry and/or ongoing need for full-dose oral or parenteral anticoagulation
* Subjects with a "currently active" second primary malignancy other than non-melanoma skin cancers. Subjects are not considered to have a "currently active" malignancy if they have completed anti-cancer therapy and are considered by their physician to be \< 30% risk of relapse.
* Pregnant or lactating women
* Known concomitant genetic or acquired immune suppression disease such as HIV

Prohibited medications:

  * At least 2 weeks since prior local radiation therapy (ie, involving \<25% of bone marrow) at the time of study entry
  * At least 4 weeks since prior radiation therapy involving ≥ 25% of bone marrow
* Treatment with CYP3A4 inducers or inhibitors during the study
