Detailed Description

Sporadic and germline BRCA mutation associated triple-negative breast cancer share several pathological and molecular similarities which have led to the exploration of DNA damaging agents like platinum compounds in patients with triple-negative breast cancer. Recent studies demonstrate that addition of neoadjuvant carboplatin to doxorubicin/cyclophosphamide/taxane-based chemotherapy improves pathological complete response in patients with stage I-III triple-negative breast cancer but also increase toxicity.

A recent study reported encouraging pathological complete response rates with a non-anthracycline carboplatin plus docetaxel neoadjuvant chemotherapy regimen in a cohort of 49 triple negative breast cancer patients. This chemotherapy regimen of carboplatin plus docetaxel yielded an overall pathological complete response rate of 65% in unselected triple-negative breast cancer with pathological complete response rates of 61% in sporadic and 77% in germline BRCA-associated triple-negative breast cancer. The chemotherapy regimen of carboplatin/docetaxel is well tolerated and should be studied further and compared with regimens that add carboplatin to the standard anthracycline/taxane containing regimens.

This is the basis for the proposed randomized neoadjuvant phase II study to further estimate and compare pathological complete response rates of carboplatin plus docetaxel x 6 cycles to carboplatin plus paclitaxel x 4 cycles followed by doxorubicin plus cyclophosphamide x 4 cycles in stage I-III triple negative-breast cancer.

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

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.

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
Number of Participants With Pathological Complete Response
Time Frame: 20 weeks
To evaluate the pathological complete response rates with neoadjuvant chemotherapy regimens of carboplatin plus paclitaxel x 4 cycles followed by doxorubicin plus cyclophosphamide X 4 cycles and carboplatin plus docetaxel X 6 cycles in subjects with stage I-III triple-negative breast cancer. Pathological complete response is defined as no evidence of disease in the breast and axilla at the time of pathology review except for DCIS.
