Arm Description
Hormone receptor negative, HER2 positive participants will receive Pyrotinib in combination with Temozolomide until disease progression, unacceptable toxicity, withdrawal of consent or death, whichever occurs first.
Hormone receptor negative, HER2 negative participants will receive SHR1316 in combination with bevacizumab plus cisplatin or carboplatin until disease progression, unacceptable toxicity, withdrawal of consent or death, whichever occurs first.
Outcomes
Primary Outcome Measures
Overall Response Rate in the CNS
CNS ORR will be assessed by the investigator according to RANO-BM criteria. According to these criteria Complete Response (CR) will be defined as the disappearance of all CNS target lesions sustained for at least 4 weeks; no new lesions, no corticosteroids; stable or improved clinically. Partial Response (PR) will be defined as a decrease of at least 30% in the sum longest diameter (LD) of CNS target lesions, taking as reference the baseline sum LD, sustained for at least 4 weeks; no new lesions; no corticosteroids; stable or improved clinically.
Secondary Outcome Measures
Clinical Benefit Rate in the CNS
CNS clinical benefit rate (CBR) will be defined as the percentage of patients who experience a CR, PR or Stable Disease (SD) for at least 24 weeks.
Progression-free survival
PFS will be defined as the time from the first dose of treatment to death or disease progression.
Overall survival
OS will be defined as the time from the first dose of treatment to death for any cause.
First progression site
The first lesion to progress.
Safety as assessed by percentage of patients with any Adverse Event
Adverse event according to NCI-CTC AE 5.0

5. Study Description
Brief Summary
The study is being conducted to assess the effectiveness and safety of treatment options for breast cancer brain metastases based on molecular typing.
Detailed Description
This is a prospective, single-arm, single-center, two cohorts, Simon's two-stage design, phase II clinical trial in HER2-positive and triple-negative breast cancer brain metastases patients. Subjects will be divided into two cohorts by hormone receptor status and HER2 status. HER2+/HR- subjects will enter Cohort A to receive pyrotinib plus temozolomide; HER2-/HR- subjects will enter Cohort B to receive bevacizumab, SHR1316 combined with cisplatin/carboplatin. Subjects in both cohorts will be treated until disease progression, toxicity is intolerable, informed consent is withdrawn, and investigators determine that medication must be discontinued. Drug efficacy and safety data will be collected.
