Vaccine Treatment of Kidney Cancer

Stopped early · Phase 2

Conditions studied: Kidney Cancer

In brief

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.

You may not qualify if…

Patients will be excluded:
Who are not willing or able to be biopsied.
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 surgical procedures or local radiotherapy within the past 3 weeks as long as all toxicities have recovered to a grade 1 or less.
Have active systemic infections, coagulation disorder, or other major medical illnesses of the cardiovascular or respiratory symptoms or any known immunodeficiency disease (Immune competence will be defined as lymphocyte count greater than 500 (grade 3 toxicity in Common Toxicity Criteria (CTC) 3); white blood cell (WBC) 1000; and absence of opportunistic infections).
Who require systemic steroid therapy.
Who are pregnant (because of possible side effects on the fetus) or who are breastfeeding, or who are unwilling/unable to practice effective birth control.
Who are known to be positive for hepatitis BsAG, or human immunodeficiency virus (HIV) antibody, or hepatitis C antibody (unless antigen negative), (because of possible immune effects of these conditions).
Who have had a known allergic reaction to Incomplete Freund's Adjuvant (MONTANIDE ISA-51) or hypersensitivity to any agent used on this protocol.
Who have a fresh tumor specimen with no evidence of FGF-5 expression on a technically adequate RT-PCR assessment.
