The duration of one treatment cycle is 21 days tpCR is defined as the absence of any residual invasive cancer on hematoxylin and eosin evaluation of the resected breast specimen and all sampled ipsilateral lymph nodes after completion of neoadjuvant therapy and surgery (that is, ypT0/is, ypN0, in accordance with the current American Joint Committee on Cancer \[AJCC\] staging system).The duration of one treatment cycle is 21 days.
- Secondary Outcome Measures
Name Time Method Clinical response Cycle 1-4. The duration of one treatment cycle is 21 days. Percentage of Participants With Complete Response, Partial Response, Stable Disease, or Progressive Disease During Cycles 1-4, According to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1. The duration of one treatment cycle is 21 days.
Percentage of Participants With Breast Pathologic Complete Response (bpCR) After completion of 4 cycles of neoadjuvant therapy The duration of one treatment cycle is 21 days. at the time of surgery bpCR is defined as the absence of any residual invasive cancer on the hematoxylin and eosin evaluation of the resected breast specimen after completion of neoadjuvant therapy and surgery (that is, ypT0/is, in accordance with current AJCC staging system).The duration of one treatment cycle is 21 days.
Event-free survival (EFS) From Baseline to EFS event or date last known to be alive and event-free (up to 5 years) EFS is defined as the time from randomization to the first documentation of one of the following events: Disease progression (before surgery) as determined by the investigator with use of RECIST v1.1 Any evidence of contralateral disease in situ was not identified as progressive disease; Disease recurrence (local, regional, distant, or contralateral) after surgery; Death from any cause.
Disease-free survival (DFS) From surgery to DFS event or date last known to be alive and event-free (up to 5 years) DFS was defined as the time from first date of no disease (i.e., date of surgery) to first documentation of one of the following events: Disease recurrence (local, regional, distant, or contralateral) after surgery. Any evidence of contralateral disease in situ was not identified as disease recurrence; Death from any cause.
Overall survival (OS) From Baseline to OS event or date last known to be alive (up to 5 years) OS was defined as the time from randomization to death from any cause.
