Primary Objective: To evaluate if low BRCA1 protein expression has a preferential effect on response when metastatic breast cancer patients are treated with DNA damaging chemotherapy agent, compared to historical controls

Secondary Objective: To evaluate if low BRCA1 protein expression has a preferential effect on tumor progression when metastatic breast cancer patients are treated with DNA damaging chemotherapy agent, compared to historical controls

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

DNA is constantly subject to damage from exposures including drugs (including chemotherapy), sunlight and aging. Certain genes in the human body help repair this damage (i.e. BRCA1 and other genes). The purpose of this study is to find out if BRCA1 protein expression has a role in response to chemotherapy drugs.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Overall Response Rate for Metastatic Breast Cancer Patients With Low BRCA1 Protein Expression in Their Tumor, Treated With Pegylated Liposomal Doxorubicin
Time Frame: Start of treatment and repeat imaging done at 9 weeks (± 7 days)
Evaluating if low BRCA1 protein expression has a preferential effect on response when metastatic breast cancer patients are treated with DNA damaging chemotherapy agent, compared to historical controls. Response rate is defined as the percentage of evaluable patients who achieve complete response (CR) or partial response (PR) as measured by RECIST 1.1 on CT or PET/CT as the best overall response.
Start of treatment and repeat imaging done at 9 weeks (± 7 days)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Progression Free Survival for Patients With Breast Cancer With Low BRCA1 Protein Expression Treated With Pegylated Liposomal Doxorubicin
Time Frame: Start of Treatment until the date of first documented progression or date of death, assessed up to an expected average of 100 weeks
Evaluating if low BRCA1 protein expression has a preferential effect on tumor progression when metastatic breast cancer patients are treated with DNA damaging chemotherapy agent, compared to historical controls. Progression free survival will be measured as the times from the start of pegylated liposomal doxorubicin to the time the patient is first recorded as having disease progression or dies. If a patient does not progress or die while being followed via tumor assessment, progression-free survival will be censored at the time of last disease assessment. The median progression free survival will be calculated in patients with low BRCA1 protein expression and intact BRCA1 protein expression. Median progression free survival will be estimated by Kaplan-Meier methodology
Start of Treatment until the date of first documented progression or date of death, assessed up to an expected average of 100 weeks
