Trial Information

A Phase II Neoadjuvant Clinical Trial to Evaluate the Efficacy of Recombinant Humanized Monoclonal Anti-VEGF Antibody rhuMab VEGF (Bevacizumab) for Renal Cell Carcinoma

Bevacizumab is a drug that binds to and inhibits VEGF, a blood-vessel stimulating agent with
unusually high levels in kidney cancer. This drug may decrease the growth of kidney cancer.

Every two week study cycle, you will receive a dose of bevacizumab intravenously (through a
needle in your vein). The first bevacizumab dose will be given over 90 minutes as a
continuous IV infusion. If the first dose is tolerated without any side effects related to
the intravenous (IV) infusion, the second dose may be delivered over 60 minutes. If the 60
minute infusion is tolerated, all doses of bevacizumab after that may be given over 30
minutes. If you experience infusion-related side effects with the 60 minute infusion, all
doses after that will be given over 90 minutes. If you experience infusion-related side
effects with the 30 minute infusion, all doses after that will be given over 60 minutes.
Other drugs, including Tylenol and Benadryl, may be given before, during, and after the
therapy to help prevent or ease side effects. These drugs may be given either by mouth or
through an IV line.

During treatment, blood samples (about 1 1/2 tablespoons) will be taken once per 2 week
cycle. Urine samples will be taken at the beginning of each cycle. At around 56 days into
treatment, tumors will be measured using X-rays or other scans.

Treatment will be stopped after 56 days of therapy. In this first phase, you will receive 4
doses of bevacizumab.

If the cancer is stable or shrinks while on bevacizumab for the first 56 days, and you
tolerated the treatment well, you will undergo surgery to remove your kidney tumor. Surgery
will be scheduled at least 4 weeks after your last dose of bevacizumab. Approximately 4
weeks after surgery, you will undergo repeat CT scans. If your cancer is stable or
continuing to shrink, you will restart treatment with bevacizumab. You will continue to
have tumor measurements by scans around every 56 days (8 weeks) while receiving bevacizumab,
if your initial scans showed evidence of tumor presence. However, If your tumor grew
substantially during the operative period, i.e. between the first set of scans on or around
day 56 and the scans performed after surgery, you will be taken off the study, and other
treatments will be offered to you.

If the cancer grew while on bevacizumab for the first 56 days, you will undergo surgery to
remove your kidney tumor. Surgery will be scheduled at least 4 weeks after your last dose
of Bevacizumab. After surgery, you will not continue on bevacizumab. Once you recover from
surgery, your doctor may recommend a different drug therapy to treat your cancer.

In some circumstances, after the first 56 days of therapy with bevacizumab, your doctors may
decide that it is not possible or helpful for your kidney to be removed because of
progression of your cancer rendering such an operation either not feasible or inappropriate
for your care. In that case, your doctors may recommend a different drug therapy for your
cancer, and you will not continue on bevacizumab.

You may be taken off study if your disease progresses or intolerable side effects occur.

If you are taken off study, you will have repeat scans, a physical examination, blood
testing (about 2 tablespoons), urine testing, and an ECG. If you have elevated blood
pressure or excess protein in your urine, you will be asked to come back every 2 months for
repeat blood pressure testing and urine testing until these levels fall to a normal range,
for up to one year.

This is an investigational study. Avastin is commercially available and approved by the FDA
for metastatic colorectal cancer and small cell lung cancer. The drug is experimental and
authorized for research purposes only in renal cell carcinoma. Up to 50 participants will
take part in this study. All will be enrolled at M. D. Anderson.

Inclusion Criteria:

- Patients with histologically or cytologically confirmed clear cell metastatic RCC who
are eligible for cytoreductive nephrectomy.

- Patients must have measurable disease, defined as a lesion that can be accurately
measured in at least one dimension (longest diameter to be recorded) and measures
greater than or equal to 20 mm with conventional techniques or greater than or equal
to 10 mm with spiral CT scan. This does not include primary tumors, which will be

- ECOG performance status less than or equal to 1

- Female patients of childbearing potential (i.e. premenopausal, no hysterectomy) must
have a normal plasma beta human chorionic gonadotropin (bHCG) within 24 hours prior
to enrolling in the study due to the possible teratogenic effect. Patients with an
elevated bHCG will undergo appropriate evaluation to rule out pregnancy (i.e.
referral to Gyn service, pelvic ultrasound) and if pregnancy is ruled out and
elevated bHCG is determined to be of tumor origin, patients will be permitted to
proceed on study.

- Patients of child fathering or childbearing potential must agree to practice a form
of medically acceptable birth control while on study, i.e. condoms.

- Patients must give written informed consent prior to initiation of therapy, in
keeping with the policies of the institution. Patients with a history of major
psychiatric illness must be judged able to fully understand the investigational
nature of the study and the risks associated with the therapy. The only approved
consent is attached to this protocol.

- Patients must have ability to comply with study and/or follow-up procedures.

- Patients must have adequate organ and marrow function within 14 days as defined
below: absolute neutrophil count >/=1,500/micro platelets >/= 75,000/micro Hgb > 9.0
g/dL (may be transfused or receive epoetin alfa permitted) total bilirubin mg/dL albumin > 3.0 g/dL serum creatinine metastases present.

Exclusion Criteria:

- Patients must not have organ allografts.

- Patients must not have had major surgical procedure, open biopsy, or significant
traumatic injury within 28 days prior to Day 0, or anticipation of need for major
surgical procedure during the course of the study (other than defined by protocol);
or fine needle aspirations or core biopsies within 7 days prior to Day 0.

- No prior malignancy is allowed, except for non-melanoma skin cancer, in situ
carcinoma of any site, or other cancers for which the patient has been adequately
treated and disease free for 5 years.

- Patients must not have received any systemic anticancer therapy. Radiation therapy is
allowed if >/= 2 weeks from study drug administration.

- Patients must not be scheduled to receive another experimental drug while on this
study. Patients are permitted to be on concomitant bisphosphonates and megestrol

- Patients must not have a primary brain tumor (excluding meningiomas other benign
lesions), any brain metastases, leptomeningeal disease, seizure disorders not
controlled with standard medical therapy, or history of stroke within the past 5

- History of serious systemic disease, including myocardial infarction or unstable
angina within the last 12 months, history of hypertensive crisis or hypertensive
encephalopathy, uncontrolled hypertension (blood pressure of >140/90 mmHg on
medication), New York Heart Association (NYHA) Grade II or greater congestive heart
failure, unstable symptomatic arrhythmia requiring medication (subjects with chronic
atrial arrhythmia, i.e., atrial fibrillation or paroxysmal supraventricular
tachycardia are eligible), significant vascular disease or symptomatic peripheral
vascular disease.

- Patients must not have history of other diseases, metabolic dysfunction, physical
examination finding, or clinical laboratory finding giving reasonable suspicion of a
disease or condition that contraindicates the use of an investigational drug or that
might affect the interpretation of the results of the study or render the subject at
high risk from treatment complications.

- Patients receiving any concomitant systemic therapy for renal cell cancer are
excluded, but patients taking bisphosphonates and megestrol acetate are not excluded.

- Patients must not require total parenteral nutrition with lipids.

- Patients must not have significant proteinuria at baseline. Patients who are
unexpectedly discovered to have greater than or equal to 1+ proteinuria on routine
urinalysis at baseline should undergo a 24 hour urine collection, which must be an
adequate collection and must demonstrate less than or equal to 1g of protein/24 hr to
allow participation in the study.

- Patients must not have a serious, nonhealing wound, ulcer, or bone fracture.

- Pregnancy (positive pregnancy test) or lactation.

- History of abdominal fistula, gastrointestinal perforation, or intra-abdominal
abscess within 6 months prior to study enrollment.
