Tivantinib and Bevacizumab in Treating Patients With Solid Tumors That Are Metastatic or Cannot Be Removed by Surgery

Study Overview
=================
Brief Summary
-----------------
This phase I trial studies the side effects of and best dose of tivantinib when given together with bevacizumab in treating patients with solid tumors that have spread to other areas of the body or cannot be removed by surgery. Tivantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as bevacizumab, may block tumor growth in different ways by targeting certain cells. Bevacizumab may also stop the growth of cancer by blocking blood flow to the tumor. Giving tivantinib together with bevacizumab may work better in treating tumor cells.

Detailed Description
-----------------
PRIMARY OBJECTIVES: I. Determine the recommended phase II dose (RP2D) of the vascular endothelial growth factor (VEGF) monoclonal antibody, bevacizumab in combination with the allosteric met proto-oncogene (MET) inhibitor, tivantinib, in patients with advanced solid tumors. SECONDARY OBJECTIVES: I. Describe the dose-limiting toxicity (DLT) and other toxicities associated with bevacizumab in combination with tivantinib as assessed by Common Terminology Criteria for Adverse Events (CTCAE) version (v) 4.0. II. Document anti-tumor activity of bevacizumab in combination with tivantinib in patients with advanced solid tumors. III. Determine the pharmacokinetics of tivantinib when administered in combination with bevacizumab in patients with advanced solid tumors. IV. Perform cytochrome P450 family 2, subfamily C, polypeptide 19 (CYP2C19) genotyping on all subjects and correlate with pharmacokinetics and toxicity. V. Assess the effect of bevacizumab plus tivantinib on plasma components of the hepatocellular growth factor (HGF)-MET signaling pathway (HGF, HGF activator [HGFA]) and VEGF signaling pathway (VEGF A, B, C, D and placental growth factor [PIGF]). VI. Assess tissue (tumor and skin) protein biomarkers before and after study treatment including MET, phospho-MET^tyrosine (Tyr)1349 and phosphor-focal adhesion kinase (FAK)^Tyr861. VII. Assess early therapy response by quantitative biomarker imaging fludeoxyglucose F 18 (F-18 FDG) positron emission tomography (PET) and magnetic imaging resonance (MRI) on a smaller sample (n up to 15) of subjects willing to participate in the imaging assessment through UPCI 12-096. OUTLINE: This is a dose-escalation study of tivantinib. Patients receive bevacizumab intravenously (IV) over 30-90 minutes on days -15, 1, and 15 (day -15 of course 1 only) and tivantinib orally (PO) twice daily (BID) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 4 weeks.

abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of tivantinib administration Negative urine or serum pregnancy test within 7 days of start of protocol therapy (for female patients who have not undergone bilateral oophorectomy or hysterectomy) Patients must have the ability to understand and the willingness to sign a written informed consent document Patients must have available archival tumor tissue (formalin-fixed, paraffin-embedded) for submission of blocks or unstained slides Exclusion Criteria: Patients who have had chemotherapy, monoclonal antibody therapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to start of study drugs or those who have adverse events not resolved to a grade 1 or neuropathy not resolved to =< grade 2 due to agents administered more than 4 weeks earlier Major hemorrhagic or thrombotic event within 3 months of start of protocol therapy Major surgery within 6 weeks or non-healing wounds Patients who have received kinase inhibitor therapy within 2 weeks of start of protocol therapy Patients who are receiving any other investigational agents Known central nervous system (CNS) disease except for treated brain metastasis; treated brain metastases are defined as having no ongoing requirement for steroids and no evidence of progression or hemorrhage after treatment for at least 3 months, as ascertained by clinical examination and brain imaging (magnetic resonance imaging [MRI] or computed tomography [CT]); (stable dose of non-enzyme-inducing anticonvulsants are allowed); treatment for brain metastases may include whole brain radiotherapy (WBRT), radiosurgery (RS; Gamma Knife, linear accelerator [LINAC], or equivalent) or a combination as deemed appropriate by the treating physician; patients with CNS metastases treated by neurosurgical resection or brain biopsy performed within 3 months prior to day 1 will be excluded History of allergic reactions attributed to compounds of similar chemical or biologic composition to tivantinib or bevacizumab, or to Chinese hamster ovary cells Tivantinib is metabolized by CYP2C19, and to a lesser extent cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4); the metabolism and consequently overall pharmacokinetics of tivantinib could be altered by inhibitors and/or inducers or other substrates of CYP2C19 and CYP3A4; while inhibitors/inducers of these cytochrome P450 isoenzymes are not specifically excluded, investigators should be aware that tivantinib exposure may be altered by the concomitant administration of these drugs; as part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, psychiatric illness/social situations that would limit compliance with study requirements Patients with clinically significant cardiovascular disease, including any of the following, are excluded: Inadequately controlled hypertension (HTN) (systolic blood pressure [SBP] > 160 mmHg and/or diastolic blood pressure [DBP] > 90 mmHg despite antihypertensive medication) History of cerebrovascular accident (CVA) within 6 months of start of protocol therapy Myocardial infarction or unstable angina within 6 months of start of protocol therapy New York Heart Association grade II or greater congestive heart failure Serious and inadequately controlled cardiac arrhythmia Significant vascular disease (e.g. significant aortic aneurysm, history of aortic dissection) Clinically significant peripheral vascular disease Untreated deep venous thrombosis (DVT) or pulmonary embolism (PE) or DVT/PE which has been treated with therapeutic anticoagulation for less than 6 weeks History of hemoptysis in excess of 2.5 mL (1/2 teaspoon ) within 8 weeks prior to first dose of study drug Pregnant women are excluded from this study, and breastfeeding should be discontinued if the mother is treated with tivantinib;
