Cediranib Maleate in Treating Patients With Recurrent or Metastatic Kidney Cancer That Cannot Be Removed By Surgery

Inclusion Criteria

• Patients must have histologically or cytologically confirmed renal cell cancer that is locally recurrent or metastatic and is not considered curable by standard therapy
• Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as > 20 mm with conventional techniques or as > 10 mm with spiral computed tomography (CT) scan; bone lesions are not considered to be measurable; all radiology must be performed within 28 days prior to registration
• Previous therapy:
• Surgery: Previous surgery is permissible; patients must be >= 4 weeks since any major surgery
• Chemotherapy: No previous systemic chemotherapy
• Immunotherapy: No previous therapy permitted
• Gene/investigational therapy: No prior therapy is permitted
• Radiation: Patients may have had radiation therapy but must have recovered from acute toxic effects prior to registration; at least 4 weeks must have elapsed since last dose of radiation before registration (exceptions may be made for low-dose, non-myelosuppressive radiotherapy); if the sole site of measurable disease is in a radiation field, there must have been documented progression at that site for patient to be eligible
• Life expectancy of greater than 3 months
• Eastern Cooperative Oncology Group (ECOG) performance status = = 60%)
• Absolute neutrophil count >= 1.5 x10^9/L
• Platelets >= 100 x10^9/L
• Total bilirubin = = 60 mL/min/1.73 m^2
• AZD2171 has been shown to terminate fetal development in the rat, as expected for a process dependent on vascular endothelial growth factor (VEGF) signaling; for this reason, women of child-bearing potential must have a negative pregnancy test prior to study entry; women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; 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

Exclusion Criteria

• Patients who have had radiotherapy, or major surgery within 4 weeks prior to entering the study or those who have not recovered from adverse events of these therapies
• Patients may not be receiving any other investigational agents nor have participated in an investigational trial
• Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to AZD2171
• Mean corrected QT interval (QTc) > 470 msec (with Bazett's correction) in screening electrocardiogram or history of familial long QT syndrome
• Greater than +1 proteinuria on two consecutive dipsticks taken no less than 1 week apart
• Uncontrolled intercurrent illness including, but not limited to hypertension, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
• Pregnant women are excluded from this study because AZD2171 is a VEGF inhibitor with known abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with AZD2171, breastfeeding should be discontinued if the mother is treated with AZD2171
• Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with AZD2171; appropriate studies will be undertaken in patients receiving combination antiretroviral
