About

Background:

Vandetanib is a drug that attacks a group of proteins on the surface of many cells, especially blood vessel cells and tumor cells.
Tumors require the development of new blood vessels in order to grow and spread.
In laboratory experiments, vandetanib slowed the growth of certain tumors and regulated their blood vessel growth.
In early clinical trials, some patients' tumors did not grow for a period of time while they were receiving vandetanib.

Objectives:

To determine whether vandetanib can cause tumors to shrink or stabilize in some patients with ovarian cancer, fallopian tube cancer or primary peritoneal cancer.
To determine, by tumor biopsy, if features of the tumor change with vandetanib treatment may predict if the tumor will likely respond to vandetanib.

Eligibility:

Women 18 years of age and older with ovarian, fallopian tube or primary peritoneal cancer that does not respond to standard treatment.

Design:

Patients take vandetanib daily, by mouth in 28-day cycles until their disease worsens or they develop unacceptable side effects.
Tumor biopsies (surgical removal of a sample of tumor tissue) are done before starting vandetanib treatment and after 6 weeks of treatment.
Patients are followed in the clinic every 4 weeks during treatment for a physical examination, blood tests, and review of laboratory studies and side effects.
Patients have a computed tomography (CT) scan every 8 weeks to monitor tumor growth and magnetic resonance imaging (MRI) before starting vandetanib treatment, on the third day after taking vandetanib and 6 weeks into treatment.
Patients quality of life is assessed with regularly scheduled questionnaires.

Full description

Background:

Epithelial ovarian cancer requires neovascularization for growth and metastasis. Anti-angiogenesis agents have been shown to have promise in the treatment of recurrent disease. Expression of vascular endothelial growth factor 2 (VEGFR2) and epidermal growth factor receptor (EGFR) has been demonstrated in ovarian cancer specimens in stroma and tumor. Blocking autocrine and paracrine loops acting through these receptors may inhibit downstream phosphorylation targets in the mitogen activated protein kinase (MAPK) and AKT pathways, thereby influencing disease progression and patient outcome.
The multi-kinase inhibitor ZD6474 (vandetanib, AstraZeneca, Zactima) blocks angiogenesis by targeting VEGFR2, and shows in vitro activity against a number of other receptor tyrosine kinases including resonance energy transfer (RET), vascular endothelial growth factor 3 (VEGFR3) and EGFR.
Clinical efficacy of ZD6474 (vandetanib) in women with refractory or relapsed epithelial ovarian cancer is unknown, but preclinical data suggests potential value.
The maximum tolerated dose of ZD6474 (vandetanib) has been determined at 300mg/day, limited by the dose-responsive adverse effect of prolonged (Q wave, T wave)QT interval.

Objectives:

To assess the clinical activity (CR - complete response, PR - partial response, or disease stabilization) of the VEGFR2 inhibitor ZD6474 (vandetanib), 300mg/d, in women with ovarian, fallopian tube or primary peritoneal cancer.
To study target signal events: quantity and activation of VEGFR2, EGFR, AKT and extracellular signal-regulated kinases (ERK).

Eligibility:

Women with biopsy-proven epithelial ovarian, fallopian tube or primary peritoneal cancer that is relapsed and/or refractory to prior therapy.
Women must have measurable disease by NCI Response Evaluation Criteria in Solid Tumors (RECIST) criteria and a sentinel lesion adequate for core biopsy through percutaneous biopsy.
Women must have had no more than four prior treatment regimens.

Design:

Women will receive 300mg of ZD6474 (vandetanib) daily, orally in 28-day cycles until disease progression, excessive toxicity, or withdrawal from study.
Biopsy of tumor will be performed prior to starting ZD6474 (vandetanib) and after six weeks of treatment. The quantity of phosphorylated VEGFR2, EGFR, ERK and AKT in the biopsy tissue will be analyzed.
Clinical outcome and toxicity will be measured and correlated with target inhibition.
Women will also undergo serial imaging with dynamic contrast-enhanced MRI to estimate tumor blood flow.
Research blood samples will be taken to assess changes in circulating cytokine concentrations.
Quality of life will be assessed during treatment.

Inclusion criteria

All patients 18 years and older with biopsy-proven epithelial ovarian, fallopian tube or primary peritoneal cancer that is relapsed or refractory to prior standard platinum-and taxane based therapy will be eligible.
Histopathologic diagnosis must be confirmed in the Laboratory of Pathology (LP), NCI. A block of the primary or later access to recut slides is required. If this is unavailable, a recent resection of a metastatic site is required for entry.
All patients must have measurable disease by NCI RECIST criteria and a sentinel lesion adequate for core biopsy through percutaneous biopsy.
Patients must have a performance status of Eastern Cooperative Oncology Group (ECOG) = 0, 1, or 2.
Patients must have good end organ function:
white blood cells (WBC) greater than 3000/mm(3)
absolute neutrophil count (ANC) greater than 1000/mm(3)
platelets greater than 150,000/mm(3)
serum creatinine less than 1.5 mg/dl
liver function tests (AST and ALT) within 2.5 times the upper limit of normal (ULN)
bilirubin less than 1.5 mg/dl
potassium between 4.0 and ULN (supplementation allowed)
magnesium (Mg) and calcium (Ca) within normal limits (supplementation allowed)
Systolic blood pressure less than 160 mm Hg and diastolic blood pressure less than 100 mm Hg (therapy permitted)
Patients must be at least 4 weeks from previous therapy (chemotherapy, hormonal therapy, and radiation therapy, alternative therapy or investigational agents). Carboplatin, must not have been received for at least 6 weeks prior to enrollment.
Patients must have received no more than 4 prior regimens for the treatment of ovarian cancer.
Patients must have recovered from any toxicity related to prior cancer therapy to NCI grade 1, except for peripheral neuropathy, which must have recovered to grade 2 or better.
Women of childbearing age and potential must agree to use adequate barrier contraception (interaction with oral contraceptives is unknown) prior to study entry, during therapy and for 3 months after completion of therapy.

All eligible patients must be registered by contacting Central Registration personnel by fax at (301) 480-0757 between the hours of 8:30am and 5:00 pm, Monday through Friday.

Exclusion criteria

Evidence of severe or uncontrolled systemic disease or any concurrent condition which in the investigators opinion makes it undesirable for the patient to participate in the trial or which would jeopardize compliance with the protocol.
Evidence of central nervous system (CNS) involvement (patients with abnormal clinical exam or history will require a head CT or MRI.
History of cardiac disorders including:
Clinically significant cardiac event such as myocardial infarction, New York Heart Association (NYHA) classification of heart disease greater than or equal to 2 within 3 months of entry, or presence of cardiac disease that, in the opinion of the investigator,increases the risk of ventricular arrhythmia.
