Summary
This study will evaluate the safety and side effects of two experimental vaccines in patients with kidney cancer and determine whether the vaccines "turn on" an immune response to the cancer. Each vaccine contains one of two peptides (pieces of proteins) from the fibroblast growth factor 5 (FGF-5) antigen, a protein produced by some cancer cells, and an oil-based liquid called Incomplete Freud's Adjuvant (Montanide ISA-51) that enhances the immune response to the vaccine. Patients 16 years of age and older who have kidney cancer that has spread beyond the kidney or whose primary kidney tumor has been removed within 6 months before entering the study and are at high risk for disease recurrence may be eligible for this study. Patients must have tissue type human leukocyte antigen serotype within HLA-A A serotype group (HLA-A2) or human leukocyte antigen serotype within HLA-A A serotype group (HLA-A3) (determined by a blood test for human leukocyte antigen (HLA) typing) and their tumors must produce the FGF-5 peptide. Candidates are screened with a physical examination, blood and urine tests, electrocardiogram (EKG), tumor biopsy (removal of a small sample of tumor for examination) in patients whose tumor is easily accessible, and scans (computed tomography (CT), bone scans) and x-rays if current scans are not available. Participants are divided into two groups according to their HLA type (HLA-A2 or HLA-A3) to receive the vaccine appropriate for their HLA type. They are then further divided into three groups: 1) Group 1 includes patients who do not need or are ineligible for treatment with interleukin-2 (IL-2), a protein made by certain infection-fighting white cells that helps fight tumors) and patients who have previously had IL-2 therapy; 2) Group 2 includes patients who require immediate treatment with IL-2; and 3) Group 3 includes patients whose cancer has been surgically removed but who are at risk for recurrence. Patients in Groups 1 and 3 receive two peptide injections four times a week every 3 weeks for up to a year, or until their tumor grows (or returns in patients in Group 3) or the side effects are too severe to continue. Tumors are evaluated with a physical examination and scans or x-rays every 12 weeks and blood tests are done every 3 weeks. Patients in Group 2 receive two peptide injections every day for 4 days, along with doses of IL-2 starting the day after the first peptide injection. The vaccines are given as injections under the skin of the thigh. IL-2 is infused through a vein over 15 minutes every 8 hours for up to 12 doses, depending on tolerance. The vaccine and IL-2 are repeated every 10 to 14 days, with tumor evaluations every 2 months. Patients stay in the hospital about 1 week during each treatment cycle to receive the IL-2. All patients undergo leukapheresis, a procedure for collecting large numbers of white blood cells. Blood is collected through a needle in an arm vein and flows through a cell separator machine, where the white cells are extracted. The rest of the blood is returned to the patient through the same needle or a needle in the other arm. The white cells are examined to evaluate how the vaccines change the action of immune cells. Some patients may undergo an additional biopsy of normal skin and tumor or lymph node to look at the effects of the vaccine on the immune cells in the tumor. Patients in Group 1 whose cancer grows and patients in Group C whose cancer returns may be offered IL-2 treatments as given to Group 2 patients, along with the peptide vaccine. If the disease responds to IL-2, the treatment may be repeated after 2 months.

Criteria
- INCLUSION CRITERIA

Patients will be screened for inclusion on this study while participating in the Surgery
Branch protocol 99-C-0128: Evaluation for the National Cancer Institute (NCI) Surgery
Branch Clinical Research Protocols

Patients with clear cell renal carcinoma must fall into one of the two following groups:

For cohort A and B, patients must have measurable metastatic renal cancer and fibroblast
growth factor 5 (FGF-5) tumor expression. For cohort C, patients are required to have had a
Stage III primary tumor (i.e. T3/T4 or N1/N2) excised within the last 6 months.

Patients must be greater than or equal to 16.

Expected survival must be greater than three months

Patients in cohorts A and B must have tumor sites safely accessible for biopsy or
indications for resection of a site of tumor (e.g. an indicated nephrectomy or symptomatic
metastasis) and have FGF-5 expression determined by RT-PCR (reverse transcription
polymerase chain reaction) and will only be eligible if it is detectable.

Must be human leukocyte antigen serotype within HLA-A A serotype group (HLA-A2+) or
HLA-A3+.

Serum creatinine of 2.0 mg/dl or less.

Bilirubin 1.6 mg/dl or less, except in patients with Gilbert's syndrome who must have a
total bilirubin less than 3.0 mg/dl.

White blood cell (WBC) 3000/mm or greater.

Platelet count 90,000mm^3 or greater.

Serum aspartate aminotransferase (AST)/alanine aminotransferase (ALT) less then three times
normal.

Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

Patients of both genders must be willing to practice effective birth control during this
trial and for three months after active treatment on this trial.

Patients who have received previous low dose interleukin-2 (IL-2) (less than 600,000 IU/kg
Food and Drug Administration (FDA) approved dosing regimen) will be eligible.

For cohort A for each human leukocyte antigen (HLA) type, if there are no clinical
responses to vaccine alone in the first 12 patients enrolled, subsequent patients must be
eligible to receive high-dose IL-2.

Patients must be able to understand and sign the informed consent document.

Eligibility for administration of IL-2.

Patients must meet the following criteria to be eligible to receive IL-2:

Patients may not have active major medical illnesses such as cardiac ischemia, myocardial
infarction, cardiac arrhythmias, obstructive or restrictive pulmonary disease.

Patients with recent prolonged history of cigarette smoking or symptoms of respiratory
dysfunction must have a normal pulmonary function test as evidenced by a forced expiratory
volume in 1 second (FEV1) greater than 60% predicted.

Patients with electrocardiogram (EKG) abnormalities, symptoms of cardiac ischemia or
arrhythmias or age greater than 50 years will have a normal stress cardiac test (stress
thallium, stress multi-gated acquisition scan (MUGA), dobutamine echocardiogram or other
stress test).

Patients must be willing to sign a durable power of attorney (DPA).

Serum creatinine of 2.0 mg/dl or less.

Total bilirubin 2.0 mg/dl or less, except in patients with Gilbert's syndrome who must have
a total bilirubin less than 3.0 mg/dl.

Patients will be excluded:

Who are undergoing or have undergone in the past 3 weeks any other form of therapy for
their cancer, or have undergone nitrosurea therapy within the past 6 weeks. All patients
toxicities must have recovered to a grade 1 or less. Patients may have undergone minor

or who are unwilling/unable to practice effective birth control.

Who are known to be positive for hepatitis BsAG, or human immunodeficiency virus (HIV)

or hypersensitivity to any agent used on this protocol.
