Brief summary: Background:

* Sorafenib and bevacizumab are anti-cancer drugs that work by targeting the blood vessels that allow tumors to grow. Using the two drugs together may more effectively block the formation of blood vessels that feed tumors.
* Sorafenib and bevacizumab both are approved by the Food and Drug Administration for use in other cancers but have not ovarian cancer. In a preliminary trial of this drug combination, however, tumors in 6 of 14 patients with ovarian cancer shrank.

Objectives:

* To determine the safety and activity of the combination of sorafenib and bevacizumab for treating patients with ovarian, fallopian and peritoneal cancer.
* To determine how sorafenib and bevacizumab may affect the cancer by measuring amounts of different proteins in small biopsy samples of tumor taken before starting treatment and after 6 weeks.

Eligibility:

* Females 18 years of age and older with ovarian, fallopian, or peritoneal cancer whose disease has not responded to standard treatment or for which no standard treatment is available.
* Patients must have not been previously treated with bevacizumab or must have had their disease worsen while taking bevacizumab-based therapy.

Design:

* Patients take 200 mg of sorafenib by mouth twice a day Monday through Friday each week and 5 mg/kg of bevacizumab through a vein every 2 weeks.
* Tumor biopsies and imaging scans (magnetic resonance imaging (MRI) and positron emission tomography (PET) are done before treatment, 3 days after beginning treatment, and 6 weeks into therapy.
* Computed tomography (CT) or other imaging tests are done every 8 weeks to evaluate response to treatment.
* History, physical examinations, blood and urine tests are done periodically during treatment for health checks and research purposes.
* About 74 patients are to be enrolled in the trial.

Detailed description: Background:

Sorafenib is an inhibitor of wild-type and mutant proto-oncogene BRaf (B-Raf) and proto-oncogene c-Raf (c-Raf) kinase isoforms in vitro, but it also inhibits mitogen-activated protein kinase (p38), proto-oncogene c-kit (c-kit), vascular endothelial growth factor receptor 2 (VEGFR-2) and platelet-derived growth factor (PDGFR)-Beta affecting tumor growth as well as possibly promoting apoptosis by events downstream of c-Raf.

Bevacizumab is a humanized immunoglobulin G 1 (IgG1) monoclonal antibody (MAb) that binds all biologically active isoforms of human vascular endothelial growth factor (vascular endothelial growth factor (VEGF), or VEGF-A) with high affinity (kd = 1.1nM).

Phase I trial of sorafenib and bevacizumab administered concurrently showed activity of the combination in patients with refractory ovarian cancer.

Objectives:

Determine the activity and tolerability of the combination bevacizumab and sorafenib in patients with refractory or recurrent epithelial ovarian, fallopian, or peritoneal cancer in patients who are bevacizumab-naive or bevacizumab-resistant.

Eligibility:

Adults with histologically documented refractory or recurrent epithelial ovarian, fallopian, or peritoneal cancer.

Patients must be off prior chemotherapy, radiation therapy, hormonal therapy, or biological therapy for at least 4 weeks.

Patients must have an Eastern Cooperative Oncology Group (ECOG) of 1 or less.

Patients must have disease that is amenable to biopsy.

Patients must have not been previously treated with bevacizumab or must have progressed on prior bevacizumab-based therapy.

Design:

Patients will be stratified on entrance to the trial based on their previous exposure to bevacizumab to either strata A (bevacizumab-naive patients) or strata B (patients previously treated with bevacizumab).

Patients will receive oral sorafenib 200 mg twice daily 5 out of 7 days each week and intravenous bevacizumab 5 mg/kg every two weeks.

Tumor biopsies will be obtained from patients before treatment and six weeks into therapy. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and fludeoxyglucose 18F-positron emission tomography (FDG-PET) will be obtained from patients before treatment, on day 3 of treatment, and six weeks into therapy.

Patients will be evaluated for response every 8 weeks using the Response Evaluation Criteria in Solid Tumors (RECIST) criteria.

Approximately 74 patients will be needed to achieve the objectives of the trial.

Eligibility criteria: * ELIGIBILITY CRITERIA:

Histopathologically documented recurrent/refractory epithelial ovarian cancer, primary peritoneal cancer or fallopian tube cancer from a previous biopsy verified by the Laboratory of Pathology, National Cancer Institute (NCI).

Patients must have a urine protein/creatinine ratio (UPC) less than 1.0 for enrollment.

No surgery, radiation therapy, chemotherapy, immunotherapy, biotherapy, or hormonal therapy (exception raloxifene for bone health) within four weeks (6 weeks for mitomycin C, carboplatin, or nitrosoureas);

No metabolically active complimentary or alternative therapy for at least 1 week, defined as any ingested or administered chemical substances including herbal medications, but not including acupuncture, hypnosis, meditation, or other non-chemical treatments.

No monoclonal antibody therapy for at least 6 weeks.

Patients must have recovered from any acute toxicity related to prior therapy, including surgery. Toxicity should be less than or equal to grade 1 (as defined by Common Terminology Criteria for Adverse Events (CTCAE v3) or returned to baseline. Peripheral neuropathy less than or equal to grade 2 will be allowed as this patient population has universally been treated with platinum-based chemotherapy with residual neuropathy being a common occurrence.

No other invasive malignancies within the past two years (with the exception of non-melanoma skin cancers, non-invasive bladder cancer, stage I endometrial cancer or cervical cancer synchronous to the ovarian cancer diagnosis and cured by surgical resection).

Patients who require hematopoietic growth factor support (e.g. epogen, darbepoetin), Non-steroidal anti-inflammatory drugs (NSAIDs), and other maintenance medications prior to study entry will be allowed to continue their supportive therapies.

Ability to tolerate orally administered medications.

Contraception is not a consideration as these patients have all had surgical removal of their reproductive organs. Pregnant women are excluded from this study because BAY 43-9006 and bevacizumab are agents with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with BAY 43-9006 and/or bevacizumab, breastfeeding should be discontinued if the mother is treated with BAY 43-9006 and/or bevacizumab.

There is no limit on the number of prior regimens with which a patient has been treated.

Patients who have been treated with bevacizumab previously are eligible for the trial if they have progressed while on bevacizumab-based therapy.

-Disease progression on bevacizumab therapy will be defined as documented increase in disease based on imaging while the patient is receiving bevacizumab or within three months of their last dose of bevacizumab.

Patients must be at least 6 weeks from their last dose of bevacizumab prior to being enrolled on study.

Patients who have a healed fistula greater than 28 days prior to enrollment are eligible (refer to section 3.2.15 for patients who have had prior bevacizumab)

EXCLUSION CRITERIA:

Moderate or massive hemoptysis or surgery within 28 days of enrollment.

Ongoing treatment with any other investigational agents.

Brain metastases

* Patients with central nervous system (CNS) metastases within the past 2 years are ineligible. Patients who have had CNS disease curatively treated and without recurrence for 2 years may be eligible. but any CNS disease that has not undergone curative therapy with radiation, gamma knife, and/or surgical therapy are ineligible.
* CNS imaging will not be mandated for all patients. However, if there is clinical suspicion of CNS involvement, a contrast computed tomography (CT) or magnetic resonance imaging (MRI) of the brain will be required.
* Patients with CNS metastases may not be on steroids for the purpose of CNS disease or edema control.
* Patients with CNS disease must be on an anti-seizure medication and that medication cannot be a CYPP4503A modulating agent.

Thrombotic or embolic events within the past 6 months such as a cerebrovascular accident (including transient ischemic attacks), pulmonary embolism, unstable angina, or myocardial infarction. Fully treated deep vein thrombosis no longer requiring anticoagulation will be allowed.

Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure (American Heart Association (AHA) Class II or worse), unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

-Patients with evidence of active infection will become eligible for reconsideration 7 days after completing antibiotic therapy.

Human immunodeficiency virus (HIV)-positive patients receiving combination anti-retroviral therapy are excluded from the study because of possible pharmacokinetic interactions with sorafenib, bevacizumab, and/or the combination.

Hypertension defined as systolic blood pressure greater than 150 mmHg or diastolic pressure greater than 90 mmHg despite optimal medical management.

Therapeutic anticoagulation with coumadin, heparins, or heparinoids.

Patients must not be taking the cytochrome p450 (CYP450) enzyme-inducing drugs phenytoin, carbamazepine, phenobarbital, St. John's wort, or rifampin.

For patients who have been previously treated with bevacizumab, any severe toxicity associated with bevacizumab while the patient was being treated with the agent will make the patient ineligible for the trial. This includes bevacizumab-induced hypertensive crisis, arterial thromboembolic events (including cardiac ischemia or cerebrovascular ischemia or other arterial thrombosis), nephrotic syndrome, gastrointestinal perforation, serious hemorrhage, and fistulas (unless the fistula completely resolved while the patient was still on bevacizumab or it has been surgically corrected).
