  • * Non-menopausal or non-surgically sterilized female patients identified as non-pregnant and non-lactating and consented to contraception both during the trial and within 6 months after the last administration of the test drug
Exclusion Criteria
  • * Metastatic BC, bilateral BC, occult BC, inflammatory BC, or with other malignant tumors
  • * Known history of hypersensitivity to the study drugs
  • * Patients who need receive other anti-tumor treatments (except for OFS) during neoadjuvant therapy as judged by the investigators

  • * Patients who participated in a clinical trial of another drug within 4 weeks prior to randomization or underwent BC-free surgery within 4 weeks or had not fully recovered after BC-free surgery
  • * Other malignancy in the past 5 years, other than cured cervical carcinoma in situ, basal or squamous cell carcinoma of skin
  • * Patients who had basic gastrointestinal diseases (especially long-term history of diarrhea or/and constipation), inability to swallow, intestinal obstruction or other factors will affect drugs administration and absorption
  • * Presence of accompanying diseases that may pose serious risks to the safety of the patient or may affect the patient's ability to complete the study (including but not limited to severe diabetes mellitus, active infection, thyroid disorders, etc.) as judged by the investigator
