Registration Number
NCT04540692
Lead Sponsor
Latin American Cooperative Oncology Group
Brief Summary

Phase III randomized clinical trial evaluating the sequencing of anthracyclines and taxanes in neoadjuvant therapy for locally advanced HER2-negative breast cancer.

Detailed Description

Multicenter, phase III, open-label, randomized clinical trial, which will include 494 patients randomized to two neoadjuvant chemotherapy arms. The treatment protocol will be the same in both groups, only the regimens sequences will be evaluated: starting with anthracycline versus taxane, with or without carboplatin for patients with triple negative subtype. The chemotherapy regimen will follow the institution's routine, which includes the use of CA in the anthracyclical phase and, in the taxane phase, the use of docetaxel every 21 days or weekly paclitaxel. The rest of the treatment (surgery, radiotherapy, hormone therapy) will not be part of the study and will be carried out according to institutional guidelines.
