Fallopian Tube Cancer, Ovarian Cancer, Primary Peritoneal Cancer
Conditions
Brief summary
The primary objective is to determine whether LY573636-sodium (hereafter referred to as LY573636) is effective in treating platinum-resistant ovarian cancer. Patients will receive an intravenous infusion of study drug once every 28 days. Computed tomography (CT) scans and CA-125 tests will be done before the first dose and then after every other treatment.
Interventions
LY573636 dose is dependent on participant's height, weight, and gender and is adjusted to target a specific maximum concentration (Cmax) based on participant laboratory parameters. LY573636 is administered every 28 days until disease progression or other criteria for participant discontinuation are met.

| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With Complete Response and Partial Response (Objective Response Rate) | Baseline to measured progressive disease up to 12.68 months | Objective response is complete response (CR) + partial response (PR), as classified by the investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST) guidelines. CR is disappearance of all target and non-target lesions; PR is ≥30% decrease in sum of longest diameter of target lesions. Objective response rate is calculated as a total number of participants with CR or PR divided by the total number of participants treated multiplied by 100. |

| Progression Free Survival | Baseline to measured progressive disease or death due to any cause up to 21.26 months | Defined as the time from date of first dose to the first observation of progression of disease (PD) or death due to any cause. PD was determined using Response Evaluation Criteria In Solid Tumors (RECIST) criteria. PD is ≥20% increase in sum of longest diameter of target lesions and/or a new lesion. |
| Percentage of Participants With Complete Response, Partial Response, and Stable Disease (Clinical Benefit Rate) | Baseline to measured progressive disease up to 21.26 months | Clinical Benefit Rate is complete response (CR) + partial response (PR) + stable disease (SD) as classified by the investigator according to the Response Evaluation Criteria In Solid Tumors (RECIST) guidelines. CR is disappearance of all target and non-target lesions; PR is ≥30% decrease in sum of longest diameter of target lesions. SD is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease. Clinical benefit rate is calculated as a total number of participants with CR or PR or SD divided by the total number of participants treated multiplied by 100. |
