Primary Outcome Measures
NameTimeMethod
Adverse events (AEs)Up to approximately 35 weeks

AEs were graded according to the National Cancer Institute's Common Toxicity Criteria for Adverse Events (CTCAE) version 5.0.

In general, AEs are graded according to the following: Grade 1 Mild AE Grade 2 Moderate AE Grade 3 Severe AE Grade 4 Life-threatening or disabling AE Grade 5 Death related to AE.

The type, grade and frequency of AEs will be reported.

Pathological Complete ResponseUp to approximately 27-30 weeks

pCR rate (ypT0/Tis ypN0) is defined as the percentage of participants without residual invasive tumor on hematoxylin and eosin evaluation of breast specimen and all sampled regional lymph nodes following completion of neoadjuvant systemic therapy by current AJCC staging criteria assessed by the local pathologist at the time of definitive surgery in all participants.

Secondary Outcome Measures
NameTimeMethod
Event-Free Survival (EFS) in all participantsUp to approximately 5 years

EFS is defined as the time from start of study treatment to any of the following events: progression of disease that precludes surgery, local or distant recurrence, second primary malignancy (breast or other cancers) or death due to any cause.

Objective Overall Response Rate (ORR)Up to approximately 25-30 weeks

ORR was defined as percentage of participants with best (confirmed) overall response (BOR) of either CR or PR. ORR was assessed by the investigator according to RECIST version 1.1 and is based on BOR, which is defined as best response recorded from start of study treatment until definitive surgery or disease progression.

Distant Disease-Free Survival(DDFS)Up to approximately 5 years

DDFS is defined as the time interval from the beginning of treatment ( such as surgery, radiotherapy or drug intervention ) to the first occurrence of distant metastasis or death from any cause.

Disease-free survival ( DFS )Up to approximately 5 years

DFS is defined as the time interval from the first day of disease-free ( i.e., the date of surgery ) to the first recording of related events, including postoperative disease recurrence and metastasis and death from any cause.
