Ph II Study of Wkly Topotecan + Bevacizumab in Plat. Resistant/Recurrent Gyn Cancers

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the clinical safety and toxicity of intravenous bevacizumab (Days 1 and 15 of a 28 day cycle) in combination with weekly topotecan (Days 1, 8, 15 of a 28 day cycle) in patients with platinum resistant recurrent ovarian, fallopian tube and primary peritoneal cancer.

Detailed Description
-----------------
This study is designed as a Phase 2 study. There are no published data on the toxicity of the combination of bevacizumab and topotecan therapy. Based on data combining bevacizumab with other chemotherapy agents in non-gynecologic solid tumors, it is not likely that the toxicity of the combination of the two drugs will be greater than the individual toxicities of each drug. The toxicities of each of these agents is quite different. Specifically the toxicity of this combination will be studied using the dose of bevacizumab used in previous phase II studies of ovarian cancer, e.g. an equivalent of 5 mg/kg weekly with treatments given at least every 3 weeks. In our study, since topotecan will be given weeks 1,2 and 3 of an every 4 week cycle, it is convenient to give bevacizumab 10 mg/kg IV every other week.

Dose was 4 mg/m2 administered IV.<br>* Other names: Hycamtin;Drug: Bevacizumab<br>* bevacizumab administered IV 10 mg/kg, days 1 and 15 of 28 day cycle.<br>* Other names: Avastin;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression Free Survival | Progression free survival(PFS)was measured by Response Evaluation Criteria in Solid Tumors (RECIST) criteria in patients with measurable disease. For patients with nonmeasurable disease, cancer antigen (CA-125) levels were used to determine response according to Rustin criteria. Progression-free survival was defined as number of months after beginning study treatment until progressive disease or death, respectively. | PFS and OS were defined as the number of months after commencing study treatment until progressive disease or death. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of Overall Survival | Overall survival was defined as the number of months after commencing study treatment to death. | PFS and OS were defined as the number of months after commencing study treatment until progressive disease or death. | 
| Objective Response Rate | RECIST criteria | Response | 
| Number or Participants With Toxicity |  | measured at each treatment cycle |
