Inclusion Criteria:

• Able to comprehend and sign an IRB approved Informed Cosent Form
• Male or female 18 years of age or older
• Female patients who are post menopausal (no menstrual period for a minimum of six months), surgically sterilized, or are using an oral or implanted contraceptive, double barrier birth control, or an IUD and have a negative serum pregnancy test upon entry into this study; or male patients willing to use contraception upon enrollment into this study
• Pathologic diagnosis of renal cell carcinoma by fine needle aspirate or tissue biopsy
• Prior nephrectomy

• Prior Therapy:

  1. Cohort 1 only: Previously received and failed one prior biotherapy, defined as IL-2 therapy or interferon-alpha (alone or in combination); Karnosky score of > or = 70%
  2. Cohort 2 only: No prior therapy except nephrectomy and fall within the Motzer intermediate group with one or two of the risk factors, as defined in teh Study Design section.
• Has bi-dimensionally measurable disease
• Has tumor tissue available for diagnostics (acceptable: biopsy, nephrectomy tissue, fine needle aspirate, or archived tissue that is formalin fixed and paraffin embedded). In cases when a fresh biopsy can be obtained, the biopsy should be divided into two; one half should be formalin fixed, and the other half frozen. Tumor samples must be received at the central laboratory prior to patient regisration.

  1. ANC > 1.5 x 109/L
  2. Platelet count > 100x 109/L

• Adequate renal function, as follows:

  1. Creatinine < or = 2.2mg/dL

• Adequate hepatic function, as follows:

  1. Alkaline phosphatase < or = 3x ULN
  2. AST < or = 3x ULN
  3. ALT < or = 3x ULN
  4. Total bilirubin < or = 1.5x ULN

Exclusion Criteria:

• Brain metastases
• Cohort 1 only: Hypercalcemia (calcium level outside the upper limit of normal; antihypercalcemic treatment is allowed)
• Cancer therapy within 30 days of ABX-EGF infusion (hormone therapy is allowed; steroid therapy is only allowed if it is replacement therapy)
• Use of any investigational drug within 30 days of ABX-EGF infusion
• Prior treatment with any anti-EGFr agents
• Left ventricular ejection fraction < 45%, as measured by MUGA Scan
• Myocardial infarction within one year prior to entering the study
• Has other cancer that has been active and required treatment within the past 5 years (prior renal cell carcinoma, basal cell carcinoma, or cervical carcinoma in situ are allowed)
• Pregnant or breast feeding female; male or female of childbearing potential (defined as: post menarche and is biologically capable of becoming pregnant) unwilling to use birth control (as defined in the inclusion criteria) during and for 1 month following treatment
• Known to be HIV positive
