Dalteparin and Sunitinib Malate as First-Line Therapy in Treating Patients With Kidney Cancer That is Metastatic or Cannot Be Removed by Surgery

PRIMARY OBJECTIVES:

I. To determine the recommended dosing for the combination of sunitinib (sunitinib malate) and dalteparin in patients with metastatic renal cell carcinoma.

II. To evaluate safety and tolerability for the combination of sunitinib and dalteparin in patients with metastatic renal cell carcinoma.

III. To determine early signs of clinical activity of the combination of sunitinib and dalteparin in patients with metastatic renal cell carcinoma.

SECONDARY OBJECTIVES:

I. To determine the clinical response rate of sunitinib and dalteparin in patients with metastatic renal cell carcinoma.

II. To determine time-to-progression (TTP) and overall survival amongst patients with metastatic renal cell carcinoma receiving sunitinib and dalteparin.

III. To determine the effect of sunitinib alone and dalteparin alone compared to the combination of dalteparin plus sunitinib on plasma coagulation parameters.

IV. To determine the effect of sunitinib alone and dalteparin alone compared to the combination of dalteparin plus sunitinib on angiogenesis parameters in blood.

OUTLINE: This is a dose-escalation study of dalteparin.

Patients receive sunitinib malate orally (PO) once daily (QD) in weeks 1-4 and dalteparin subcutaneously (SC) QD in week 6 during course 1. In all subsequent courses, patients receive sunitinib malate PO QD in weeks 1-4 and dalteparin SC QD in weeks 1-6. Courses repeat every 6 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 4 weeks and then every 3 months for 3 years.

• Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
• Ability to understand and the willingness to sign a written informed consent document
• Except for Dalteparin that will be administered as a study drug, the patients should not take any other anticoagulants or antiplatelet agents during the study, including but not limited to nonsteroidal anti-inflammatory drugs (NSAID) (any dose of aspirin), warfarin or other anticoagulants

Exclusion Criteria:

• Patients may not be receiving any other investigational agents
• Patients with known central nervous system (CNS) metastases; patients should have a head CT/magnetic resonance imaging (MRI) within 4 weeks prior to treatment initiation; any imaging abnormality indicative of CNS metastases will exclude the patient from the study
