General information about the trial
|
|||
Main objective of the trial |
To determine the percentage of patients with poor response [residual cancer burden III (RCB-III) rate] in contrast to good response [residual cancer burden 0/I RCB-0/1] measured by the Symmans criteria [20] at surgery, in patients with stage II-III luminal breast cancer treated with neoadjuvant nab-paclitaxel.

Protection of trial subjects |
Not applicable. It was not necessary to applied extra measures for protection of the subjects out of the
good clinical practice environment.

Background therapy |
The use of chemotherapy in the neoadjuvant setting is a good treatment choice for either premenopausal ER positive patients, or patients with high Ki-67. nab-Paclitaxel is a novel formulation of paclitaxel that consists of nanometer-range particles of paclitaxel bound of human serum albumin. nab-Paclitaxel exploits the role of of albumin as the natural carrier of hidrofobic molecules in human to increase paclitaxel delivery to tumor cells, eliminating the need for solvents. nab-Paclitaxel (every three weeks) showed a significant higher ORR and longer TTP than standard paclitaxel (every three weeks) in a phase III study in metastatic breast cancer. Weekly nab-Paclitaxel also demonstrated a superior efficacy and safety than every three weeks docetaxel in a randomized phase II study. The nab-paclitaxel weekly dose of 150 mg/m2 appeared to be the most effective. This study proposes evaluating the activity and safety profile of weekly nab-paclitaxel administered at a dose of 150 mg/m2 (on days 1,8 and 15 every four weeks) for 4 cycles cycles as the neoadjuvant treatment of women with positive estrogen receptors and negative HER2, amenable to receive chemotherapy. Likewise, biomarkers will be investigated for the purpose of aiding and improving the understanding of the efficacy, safety and mechanism of action of nab-paclitaxel in these patients. | ||
