The purposes of this study are:

1. To determine the dose limiting toxicity (DLT) and the maximum tolerated dose (MTD) weekly of topotecan in combination with standard dose gefitinib in patients with relapsed, platinum-resistant, ovarian, peritoneal or fallopian tube cancers that are epidermal growth factor receptor (EGF-R) positive (\>/= 1+).
2. To determine the response rate and response duration in this patient population treated with the maximum tolerated dose (MTD) of topotecan administered on a weekly schedule in combination with standard dose gefitinib, given by way of the mouth (PO) daily.

Gefitinib inhibits the activity of a molecule present on the cancer cell that plays a role in cancer cell growth. Topotecan is an FDA approved drug used to treat ovarian cancer that is still present after treatment with chemotherapy. It is also used to treat recurrent ovarian cancer (patients whose cancer returns after they have been cancer-free for a period of time).

Before treatment starts, you will have a complete physical exam, routine blood tests (about 2-3 teaspoons), a chest x-ray, and a CT scan or MRI. Women who are able to have children must have a negative blood pregnancy test.

There are 2 phases to this study. In the first phase, 3 different dose levels of topotecan are being studied. The dose of topotecan that you receive will depend on when you are enrolled. It will also depend on whether or not other participants had side effects from their treatment. Although the dose of topotecan will vary, the dose of gefitinib is the same for all participants. Up to 6 participants may be treated at each dose. The goal of this portion of the study is to find the highest safe dose of this drug combination. Up to 18 patients will be treated on this part of the study.

Once the highest safe dose of topotecan has been found, the second phase of the study will begin. In this phase, all participants will receive the same dose of topotecan and gefitinib. Up to 40 patients will be enrolled in this part of the study (but 6 will be from the 1st portion of the study.

Each treatment cycle is 28 days long. You will take one gefitinib tablet by mouth every day beginning on Day 1. In addition, you will be given topotecan through a catheter (tube) placed in a vein over 30 minutes on Days 1, 8, and 15.

Blood tests to check your kidney, liver, and bone marrow function and a complete checkup (physical examination, including a pelvic and rectal exam) will be done before each course of therapy and a month after treatment ends. About 2-3 teaspoons of blood will be collected for routine blood tests each time blood is drawn during this study. Follow up CT scans or MRI scans will be done after every 2 to 3 cycles to evaluate your response to treatment.

You will be taken off study if your disease gets worse or intolerable side effects occur. If you have a complete response to this therapy (no evidence of cancer) then treatment will continue for an additional 6 months and then stop. All treatment is given on an outpatient basis at UTMDACC.

You will be monitored for at least 30 days after your last dose of therapy. If you have side effects related to this treatment combination, you will be monitored longer (until the side effects have gone away).

This is an investigational study. Both gefitinib and topotecan are FDA approved and commercially available. However, their use together in this study is investigational. A total of up to 52 patients will take part in this study. All will be enrolled at UTMDACC.

Topotecan and Gefitinib (Iressa) for Ovarian, Peritoneal, or Fallopian Tube Cancer

A Phase I/II Study of Weekly Topotecan and Gefitinib (Iressa) in Patients With Platinum-Resistant Ovarian, Peritoneal, of Fallopian Tube Cancer

Dose-limiting toxicity defined as any Grade 4 hematological toxicity and any \> Grade 3 non-hematologic toxicity. The DLT (dose-limiting toxicity) is defined as any Grade 4 hematological toxicity and any \> Grade 3 non-hematologic toxicity.

Maximum tolerated dose is highest dose level in which 6 patients treated with at most 1 experiencing DLT.

Measurable disease defined as at least one lesion that can be accurately measured in at least one dimension. Complete Response (CR): disappearance of all target and non-target lesions and no evidence of new lesions. Partial Response (PR): At least 30% decrease in sum of longest dimensions (LD) of all target measurable lesions. Increasing Disease: At least a 20% increase in sum of LD of target lesions taking as reference smallest sum LD or appearance of new lesions within 8 weeks of study entry. Progression on existing non-target lesions, other than pleural effusions without cytological proof of neoplastic origin. Death due to disease without prior objective documentation of progression. Global deterioration in health status attributable to disease requiring a change in therapy without objective evidence of progression.
