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).
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
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
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.
- 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
- 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

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 0-1.
- 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
- Patient must have an adequate renal function as defined by:
- a serum creatinine ≤1.5 x the institutional upper limit of normal obtained
within 14 days prior to start of therapy and a urine protein:creatinine (UPC)
ratio of ≤ 1.0.
- Patients must be able to take oral medications
- Patients may not have ongoing problems with bowel obstruction or short bowel syndrome
characterized by grade 2 or greater diarrhea or malabsorptive disorders.
- Patients must have the following hematological criteria:
- Hemoglobin of >10gm/dL,
- White blood cell count >2500,
- Platelets >80,000
- Patients must be ≥ 18 years of age.
- 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
- 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.

conditions that do not permit medical follow-up or compliance with the study

participation in an experimental drug study.
- Baseline blood pressure of < or equal to 150/100 mmHg. Patients with a blood pressure
