Bevacizumab and Erlotinib Study in Advanced Ovarian Cancer
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).

- Objective Response (Complete Partial, Stable and Progression) [ Time Frame: 06.16.2005 to 10.05.2009 ] [ Designated as safety issue: No ]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 ] [ Designated as safety issue: No ]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)
- Progression Free Survival(PFS) [ Time Frame: June 2005 to October 5, 2009 ] [ Designated as safety issue: No ]PFS was defined as the time from the start of therapy to the time of the first documentation of progression(progression=20% increase in sum of longest diameters of target measurable lesions over smallest sum observed or baseline, progression of non-measurable disease in the opinion of treating physician, appearance of new lesion/site, Death due to disease), symptomatic deterioration (global deterioration of health status requiring discontinuation of treatment without objective evidence of progression), or death due to any cause;

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.
