Study of Bevacizumab/Doxil in Treatment of Platinum-Resistant/Refractory Ovarian Cancer (CA)

Phase 2
Completed
Conditions
Ovarian Cancer
Interventions
Registration Number
NCT00945139
Lead Sponsor
New Mexico Cancer Care Alliance
Brief Summary

The purpose of this research study is to test the safety, tolerability, and effectiveness of two chemotherapy drugs, pegylated liposomal doxorubicin (Doxil) and bevacizumab (Avastin). How Doxil is metabolized and excreted from the body will also be studied.

Detailed Description

Avastin:

Avastin is a humanized monoclonal antibody (a type of protein that is normally made by the immune system to help defend the body from infection and cancer). Avastin has been approved for the treatment of colorectal cancer and lung cancer. Avastin is investigational for the treatment of ovarian cancer and has not been approved by the United States Food and Drug Administration (FDA) for this use.

Avastin is thought to work by attaching to a protein called vascular endothelial growth factor (VEGF) to block its action. VEGF plays a role in the formation of both normal and abnormal blood vessels. It is present in normal tissues, but is produced in excess by most solid cancers (tumors). In cancer, VEGF helps blood vessels bring nutrients to tumor cells, allowing the tumor cells to grow. In laboratory studies with human cancer cells grown in animals, Avastin has been shown to prevent or slow the growth of different types of cancer cells by blocking the effects of VEGF.

Doxorubicin:

Doxorubicin is a type of antibiotic that is only used in cancer chemotherapy. It slows or stops the growth of cancer. Doxorubicin has been approved by the FDA to treat cancers of the head, neck, cervix, vagina, testes, prostate, uterus and Ewing's tumor.

Primary Outcome Measures
NameTimeMethod
Progression Free Survival (PFS) by GCIC CriteriaUp to 25 months

Using GCIC criteria, progression is defined as CA-125 levels greater than, or equal to, 2 times the upper limit of a reference range on 2 occasions and at least 1 week apart.

Progression Free Survival (PFS) by RECIST CriteriaUp to 25 months

Tumor response is evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST) (version 1.0). Target lesions are assessed by hysical exam and/or computerized tomography (CT): Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Stable Disease (SD), neither sufficient decrease in the sum of the longest diameter of target lesions to qualify for PR nor sufficient increase in the sum of the longest diameter of target lesions to qualify for Progressive Disease; Progressive Disease (PD), 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions

Secondary Outcome Measures
NameTimeMethod
Overall Survival4 years

The time from treatment initiation to death by any cause

Overall Response Rate (ORR) by RECIST3 years

ORR is the sum of the percentages of patients achieving complete and partial responses. Tumor response is evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST) (version 1.0)

Overall Response Rate (ORR) by GCIC Criteria3 years

A response according to GCIC criteria has occurred if there is at least a 50% reduction in CA 125 levels from a pretreatment sample. The response must be confirmed and maintained for at least 28 days. Patients can be evaluated according to CA-125 only if they have a pretreatment sample that is at least twice the upper limit of normal and within 2 weeks prior to starting treatment.

Clinical Benefit Rate (by RECIST)3 years

Clinical Benefit Rate (CBR) is the sum of the percentages of patients achieving complete response, partial response, and stable disease. Tumor response is evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST) (version 1.0). Target lesions are assessed by physical exam and/or computerized tomography (CT): Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Stable Disease (SD), neither sufficient decrease in the sum of the longest diameter of target lesions to qualify for PR nor sufficient increase in the sum of the longest diameter of target lesions to qualify for Progressive Disease; Progressive Disease (PD), 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions
