Bevacizumab Plus Ixabepilone to Treat Patients With Advanced Kidney Cancer

Completed · Phase 2

Conditions studied: Renal Cell Carcinoma

In brief

Background: * Substantial preclinical antitumor synergy supports the exploration of the combination of antiangiogenic compounds (including sunitinib and bevacizumab) plus ixabepilone. In Vivo, synergistic activity between ixabepilone and bevacizumab has been demonstrated using the 151-B human renal carcinoma xenograft model and this synergy compares favorably with other antiangiogenic inhibitors (i.e. sunitinib). * Combination therapies of bevacizumab with chemotherapy demonstrated improved benefit compared with single-agent cytotoxics in multiple animal models and in humans. * Clinical activity of both compounds used as single agents has been demonstrated in a broad spectrum of solid tumors. Bevacizumab and ixabepilone, when used as a single agent, have demonstrated substantial activity in renal cell carcinoma. * Phase II studies with bevacizumab and ixabepilone suggest the absence of overlapping toxicities. * Development of a well-tolerated and active bevacizumab/ixabepilone combination has the potential to further improve the treatment of metastatic renal cell carcinoma (mRCC), and could represent a second-line option after sunitinib or sorafenib are no longer of benefit or are intolerable. Primary Objectives: * Determine the objective response rate of the combination of ixabepilone and bevacizumab in patients with relapsed or refractory mRCC. * Determine progression-free survival. * Characterize the toxicity of the combination of ixabepilone and bevacizumab in patients with mRCC. * Determine changes in biomarkers and evaluate correlation with clinical outcomes. Eligibility: * Pathologic confirmation of renal cell carcinoma (clear cell histology) by the Laboratory of Pathology, National Cancer Institute (NCI), or the Medical University of South Carolina. * Presence of metastatic renal carcinoma, after progression or intolerance to Vascular endothelial growth factor receptor (VEGFR) inhibitors (sunitinib and/or sorafenib). * Adequate organ and bone marrow function. Design: * Multi-center, open labeled phase II study * Following a Simon two-stage optimal design, a maximum of 58 patients with metastatic RCC will be accrued. * Ixabepilone will be administered daily as a one hour infusion on five successive days (daily x 5), every three weeks (one cycle equals 3 weeks or 21 days +/- 5 days). Following cycle 6, cycles will be spread out to 4 weeks or 28 days +/- 5 days. The starting dose will be a daily dose of 6 mg/m(2)/day, for a total per cycle dose of 30 mg/m(2). * In addition, 15 mg/kg bevacizumab will be administered intravenously on day 1 of each cycle. The first infusion of bevacizumab will be 90 minutes in duration, the second 60 minutes in duration, and in all subsequent cycles bevacizumab will be infused over 30 minutes if prior infusions are well tolerated.

You may not qualify if…

Subjects presenting with any of the following will not be included in the study:
Invasive procedures defined as follows:
Major surgical procedure, open biopsy or significant traumatic injury within 6 weeks prior to Day 1 therapy
Anticipation of need for major surgical procedures during the course of the study
Minor surgery, such as port-a-cath placement, and dental procedures, within 2 weeks.
(There will be no delay for percutaneous core biopsies or peripherally inserted central catheter (PICC)/internal jugular (IJ) line placement)
Cumulative radiation therapy to greater than 25% of the total bone marrow.
History of uncontrolled or labile hypertension, defined as blood pressure greater than 160/90 mm Hg (NCI CTCAE v.3.0 through 12/31/10 and version 4.0 beginning 1/1/11 grade greater than or equal to 2), on at least 2 repeated determinations on separate days within 15 days prior to study enrollment.
Any of the following within 6 months prior to study enrollment: myocardial infarction, severe/unstable angina pectoris, coronary/peripheral artery bypass graft, New York Heart Association (NYHA) class III or IV congestive heart failure; cerebrovascular accident or transient ischemic attack, grade greater than or equal to 2 peripheral neuropathy, peptic ulcer disease, erosive esophagitis or gastritis, infectious or inflammatory bowel disease, diverticulitis, or other thromboembolic event.
Symptomatic spinal cord compression.
Evidence of clinically significant bleeding diathesis or underlying coagulopathy.
Antiretroviral therapy for human immunodeficiency virus (HIV) disease.
Pregnant (positive pregnancy test) or nursing women. Both fertile men and women must agree to use adequate contraceptive measures during study therapy and for at least 6 months after the completion of bevacizumab therapy.
Other severe acute or chronic medical or psychiatric condition, or significant laboratory abnormality requiring further investigation that may cause undue risk for the subjects safety, 18 inhibit protocol participation, or interfere with interpretation of study results, and in the judgment of the investigator would make the subject inappropriate for entry into this study.
Prior therapy with bevacizumab
Prior therapy with ixabepilone.
Patients on anticoagulant therapy will be evaluated on a case by case basis for inclusion.
Serious or non-healing wound, ulcer or bone fracture
History of abdominal fistula, gastrointestinal perforation or intra-abdominal abscess within 6 months prior to day 1
Significant vascular disease (e.g., aortic aneurysm, requiring surgical repair or recent peripheral arterial thrombosis) within 6 months prior to Day 1
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 anticonvulsants are allowed). Treatment for brain metastases may include whole brain radiotherapy (WBRT), radiosurgery (RS; Gamma Knife, linear particle 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.
Patients with known hypersensitivity of Chinese hamster ovary cell products or other recombinant human antibodies
Patients receiving cytochrome P450 3A4 (CYP3A4) inhibitors in section 3.6 that cannot be discontinued.
