Kidney Cancer Clinical Trial
Sunitinib Malate in Treating Patients With Previously Untreated Metastatic Kidney Cancer
Summary
RATIONALE: Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor.
PURPOSE: This phase II trial is studying how well sunitinib malate it works in treating patients with previously untreated metastatic kidney cancer.
Full Description
PRIMARY OBJECTIVES:
I. To determine the feasibility of intermittent sunitinib therapy in patients with metastatic renal cell carcinoma (RCC).
SECONDARY OBJECTIVES:
I. To determine the clinical outcome (response rate and overall progression-free survival) in metastatic renal cell carcinoma patients treated with intermittent sunitinib therapy.
II. To evaluate the toxicity of intermittent sunitinib therapy in patients with metastatic renal cell carcinoma.
III. To assess the feasibility of detecting circulating tumor cells (CTCs) in RCC patients and investigate the association between the VEGF -634 genotype and the occurrence of hypertension in sunitinib-treated RCC patients.
OUTLINE:
Patients receive oral sunitinib malate once daily on days 1-28. Sunitinib dosing schedule may be changed to 14 days on followed by 7 days off, and repeated for a 6-week cycle, at the discretion of the treating physician for toxicity purposes. Cycles will be defined as 6 week intervals regardless of dosing interruptions. All patients will be treated for 4 cycles in the absence of unacceptable toxicity or RECIST-defined progressive disease.
Eligibility Criteria
Inclusion Criteria:
Histologically or cytologically-proven advanced RCC with a component of clear cell histology
Measurable disease per RECIST criteria
ECOG performance status 0-1
Prior nephrectomy is NOT required
Serum aspartate transaminase (AST; serum glutamic oxaloacetic transaminase [SGOT]) and serum alanine transaminase (ALT; serum glutamic pyruvic transaminase [SGPT]) ≤ 2.5 x laboratory upper limit of normal (ULN)
Total serum bilirubin ≤ 2.0 x ULN
Absolute neutrophil count (ANC) ≥ 1500/uL
Platelets ≥ 100,000/uL
Hemoglobin ≥ 8.0 g/dL (transfusion permitted)
Serum calcium ≤ 12.0 mg/dL
Serum creatinine ≤ 2.5 mg/dL
Patients with history of brain metastases can be enrolled at a minimum of 2 weeks following the completion of surgery, gamma knife or whole brain radiotherapy; repeat brain MRI not required for eligibility
Signed and dated informed consent document indicating that the patient (or legally acceptable representative) has been informed of all pertinent aspects of the trial prior to enrollment
Exclusion Criteria:
Prior systemic treatment for advanced RCC. Prior adjuvant therapy (any drug) is allowed if end of adjuvant therapy was more than 1 year prior to start of sunitinib on this protocol.
Any of the following within the 6 months prior to study drug administration: myocardial infarction, severe/unstable angina, severe peripheral vascular disease (claudication) or procedure on peripheral vasculature, coronary/peripheral artery bypass graft, New York Heart Association grade II or greater congestive heart failure, cerebrovascular accident or transient ischemic attack, clinically significant bleeding or pulmonary embolism
Hypertension that cannot be controlled by medications to < 160/90 mmHg
Known human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS)-related illness
Pregnancy or breastfeeding
Other severe acute or chronic medical or psychiatric conditions or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, and in the judgment of the investigator would make the patient inappropriate for entry into this study
