Overview
Brief Summary
The purpose of this project is to determine if a new combination of drugs, erlotinib (Tarceva™) and bevacizumab is safe and effective for treating women diagnosed with ovarian cancer whose cancer has progressed while on prior standard chemotherapy treatment with a taxane (paclitaxel or docetaxel) and a platinum (cisplatin or carboplatin).
Detailed Description
Erlotinib and bevacizumab, novel biologics, offer a new regimen for the treatment of ovarian cancer in women who are refractory to standard drug regimens. Because bevacizumab is an anti-angiogenesis drug and erlotinib is an EGFR receptor inhibitor their combination would lead to the inhibition of multiple signal transduction pathways and the reversal of cancer progression in this difficult to treat population. The study seeks to determine the efficacy and safety of the EGFR receptor inhibitor, erlotinib plus the anti-angiogenesis VEGF ligand inhibitor bevacizumab in women with platinum and taxane refractory ovarian cancer. The study design is a non-randomized, open label, single center Phase II trial using a Simon two stage design. Eligible patients are women who have a histologically or pathologically confirmed diagnosis of epithelial carcinoma of the ovary or primary peritoneal carcinoma who have relapsed or are refractory to therapy after primary treatment of their disease. Patients will be treated with erlotinib 150 mg/day orally and bevacizumab 10mg/kg every two weeks plus or minus one day intravenously. Forty patients will be enrolled in the study. Initially 20 eligible patients will be accrued. If one or no confirmed response is observed, the trial will be closed and the agents considered inactive. Otherwise, 20 additional eligible patients will be accrued for a total of 40 patients. Eight or more responses out of 40 will be considered evidence warranting further study of the agents provided other factors, such as progression-free and overall survival, also appear favorable. Previous studies of this combination in non-small cell lung cancer, renal cell carcinoma and metastatic breast cancer have indicated a potential synergistic effect for these two agents. Preliminary data for the use of bevacizumab in advanced ovarian cancer indicates that this agent has single-agent activity. As a result, the researchers are interested in exploring the role of the combination of erlotinib and bevacizumab in advanced ovarian cancer.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Histologically or pathologically confirmed diagnosis of epithelial carcinoma of the ovary or primary peritoneal carcinoma.
- •Relapsed after prior therapy with taxane and platinum-based therapy, within 6 months of completing, or had a best response of stable disease during no more than two prior chemotherapy treatments with a platinum (either cisplatin or carboplatin) and a taxane (paclitaxel or docetaxel). These agents may have been administered concurrently or sequentially. Besides the primary chemotherapy, two additional chemotherapy regimens are allowed. Hormonal therapy is allowed and will not be counted as a chemotherapy regimen.
- •Up to one year of consolidation treatment with intraperitoneal and intravenous administered chemotherapy drugs to consolidate a clinical complete remission is allowed.
- •Patients must have elevated CA-125 or measurable disease.
- •For patients who do not have RECIST measurable disease, an elevated CA-125 (greater than two times the institutional upper limit of normal) will be required for enrollment.
- •Debulking surgery for relapsed disease is allowed but must be completed at least 28 days prior to the first day of study therapy. Patient must have recovered from all side effects of surgery including a completely healed surgical incision.
- •Patient must have a Zubrod performance status of 0-
- •Patient must have adequate hepatic function as defined by:
- •a serum bilirubin ≤1.5 x the institutional upper limit of normal (IULN),
- •SGOT or SGPT ≤2.5 x the institutional upper limit of normal obtained within 14 days prior to start of therapy
Exclusion Criteria
- •Subjects with mixed mullerian tumors and borderline ovarian tumors are excluded. Patients with a history of borderline ovarian tumors that have evolved into higher grade tumors will be eligible.
- •The patient must not have received chemotherapy, biologic therapy or any other investigational drug for any reason within 28 days prior to start of therapy and must have recovered from toxicities of prior therapy to grade 1 or less with the exception of alopecia.
- •Patient must not be pregnant or nursing because bevacizumab or erlotinib maybe harmful to the developing fetus and newborn. Women of reproductive potential must have a negative serum pregnancy test within 7 days prior to study consent. Post-menopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential. Patients of reproductive potential must agree to employ an effective barrier method of birth control throughout the study and for up to 3 months following discontinuation of study drug.
- •Patients should not have psychological, familial, sociological, or geographical conditions that do not permit medical follow-up or compliance with the study protocol.
- •Except for cancer-related abnormalities, patients should not have unstable or preexisting major medical conditions.
- •Patients should not have any medical life-threatening complications of their malignancies
- •Patients should not have a known severe and/or uncontrolled concurrent medical disease (e.g., uncontrolled diabetes, uncontrolled chronic renal or liver disease, active uncontrolled infection, or HIV)
- •Current, recent (within 4 weeks of the first infusion of this study), or planned participation in an experimental drug study.
- •Baseline blood pressure of \< or equal to 150/100 mmHg. Patients with a blood pressure reading above this level should be initiated on anti-hypertensive therapy and may be considered for protocol treatment when their blood pressure is adequately controlled.
- •New York Heart Association (NYHA) Grade II or greater congestive heart failure

Outcomes
Primary Outcomes
Objective Response (Complete Partial, Stable and Progression)
Time Frame: 06.16.2005 to 10.05.2009
Objective response was defined using standard RECIST criteria. CR(complete response)= disappearance of all target lesions PR(partial response)=30% decrease in the sum of the longest diameter of target lesions PD(progressive disease)=20% increase in the sum of the longest diameter of target lesions SD(stable disease)= small changes that do not meet above criteria
Median Response Duration (Weeks)
Time Frame: 1 week to 96 weeks
Response duration=time (in weeks) between date of measurable response and date of progression (progression=20% increase in the sum of longest diameters of target measurable lesions over smallest sum observed or baseline, progression of non-measurable disease in opinion of treating physician, any new lesion/site, death due to disease)if known or the date the subject went off protocol if they were still considered responders (ie do not qualify as progression) or are stable (Does not qualify for CR, PR, progression or Symptomatic Deterioration)
Secondary Outcomes
- Progression Free Survival(PFS)(June 2005 to October 5, 2009)
