Study treatmentBL-M07D1Participants receive BL-M07D1 + Pertuzumab with or without Taxane for the first cycle (3 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.

Primary Outcome Measures
NameTimeMethod
Pathological complete response (pCR) rateUp to approximately 48 months

Pathological complete response (pCR) rate will be investigated.

Secondary Outcome Measures
NameTimeMethod
Event-free survival (EFS)Up to approximately 48 months

Event-free survival (EFS) is defined as the time between the day the subject is randomized and the first occurrence of any event.

Invasive disease-free survival (IDFS)Up to approximately 48 months

Invasive disease-free survival (IDFS) is defined as the time interval from the date of radical surgery to the presence of ipsilateral or contralateral recurrence of invasive breast cancer, locoregional recurrence, distant recurrence, or death from any cause, whichever occurs first.

Overall Survival (OS)Up to approximately 48 months

Overall survival (OS) is defined as the time between the day the subject is randomized and the subject's death.

Treatment Emergent Adverse Event (TEAE)Up to approximately 48 months

TEAE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally emerging, or any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition during the treatment of BL-M07D1. The type, frequency and severity of TEAE will be evaluated during the treatment of BL-M07D1.
