Trial Outcomes & Findings for Neoadjuvant Study of Two Platinum Regimens in Triple Negative Breast Cancer (NCT NCT02413320)

NCT ID: NCT02413320

Last Updated: 2021-05-10

Results Overview

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.
