Status:
Completed
Trial end date:
2008-08-01
Target enrollment:
0
Participant gender:
All
Summary
RATIONALE: Sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase II trial is studying how well sunitinib works in treating patients with brain metastases caused by kidney cancer or melanoma.
Phase:
Phase 2
Accepts Healthy Volunteers?

Criteria
DISEASE CHARACTERISTICS:

- Histologically confirmed melanoma or renal cell carcinoma

- Metastatic brain disease

- Must have assessable target intracranial lesion(s), defined as measurable disease ≥ 10
mm in longest diameter that is not appropriate for stereotactic radiosurgery or
surgical resection

- Lesions previously treated with radiosurgery AND not eligible for resection can
only be used as target lesions if there has been true tumor progression on
baseline scan (i.e., ≥ 20% increase in longest diameter of lesion) rather than
radionecrosis

- True progression must be confirmed by PET scan or other corroborating
imaging used to distinguish radionecrosis

- No leptomeningeal metastases or primary dural metastases

PATIENT CHARACTERISTICS:

- ECOG performance status (PS) 0-1 OR Karnofsky PS 60-100%

- Not pregnant or nursing

- Negative pregnancy test

- Fertile patients must use effective contraception

- Total leukocyte count ≥ 3,000/mm³

- ANC ≥ 1,500/mm³

- Platelet count ≥ 100,000/mm³

- Creatinine ≤ 2.0 times upper limit of normal (ULN)

- Bilirubin ≤ 1.5 times ULN

- Hemoglobin ≥ 9.0 g/dL

- Calcium ≤ 12.0 mg/dL

- AST and ALT ≤ 1.5 times ULN

- PT ≤ 1.5 times ULN

- No other malignancy within the past 5 years except adequately treated basal cell or
squamous cell skin cancer or carcinoma in situ of the cervix

- No uncontrolled medical illness including, but not limited to, any of the following:

- Hypertension (i.e., blood pressure > 150/100 mm Hg)

- Thyroid disease

- Severe valvular disease

- Severe pulmonary disease

- HIV/AIDS

- Severe psychiatric illness

- No cardiac dysrhythmia ≥ grade 2

- No prolonged QTc interval on baseline EKG

- No systemic hemorrhage ≥ grade 2 within the past 4 weeks

- No CNS hemorrhage ≥ grade 2

- Grade 1 (asymptomatic) CNS hemorrhage allowed at investigator's discretion

- None of the following within the past 6 months:

- Myocardial infarction

- Unstable angina

- Symptomatic congestive heart failure

- Stroke/transient ischemic attack

- Pulmonary embolism

- Ejection fraction ≥ 50% by baseline echocardiogram OR < 20% decrease in ejection
fraction from a prior study

PRIOR CONCURRENT THERAPY:

- No prior multi-targeted tyrosine kinase inhibitor therapy (e.g., sunitinib malate or
sorafenib)

- No coronary/peripheral arterial bypass surgery within the past 6 months

- More than 4 weeks since prior surgery and recovered

- More than 4 weeks since prior and no other concurrent experimental therapy or
cytotoxic chemotherapy

- More than 4 weeks since prior immunotherapy

- More than 2 weeks since prior stereotactic radiosurgery and recovered

- More than 7 days since prior and no concurrent drugs that interact with CYP3A4 family,
including enzyme-inducing antiepileptic drugs, warfarin, or Hypericum perforatum
extract (St. John's wort)
