Outcome Measures

Primary Outcomes (1)

  • Progression free survival(PFS)

    calculated from the first administration time of the study drug to the disease progress or death. If the patient does not have PD or death on the study deadline, or has received other anti-tumor treatment, the deadline shall be the last efficacy evaluation result before the deadline or the start date of other anti-tumor treatment (whichever occurs first)

    2 year

Secondary Outcomes (5)

  • Objective response rate (ORR)

    2 year

  • Disease control rate (DCR)

    2 year

  • Duration of remission (DoR)

    2 year

  • Total survival (OS)

    2 year

  • time to treatment failure(TTF)

Study Arms (1)

four-drug treatment group

EXPERIMENTAL

CDK4/6 inhibitor (Qilu): 125mg, oral Qd from the 1st to the 21st day of the 28 day cycle Trastuzumab (Hanquyou): on the first day of the 21 day cycle, the initial dose was 8mg/kg, and the intravenous infusion was 90 minutes; Every 3 weeks thereafter, the dose is 6mg/kg, and the intravenous infusion is 30\~90 minutes Pertuzumab: on the first day of the 21 day cycle, the initial dose was 840mg, intravenous infusion was 60 minutes, and then once every 3 weeks, the dose was 420mg, and the infusion time was 30-60 minutes. Letrozole selected by the doctor: 2.5mg, oral Q24H or exemestane from the 1st to the 21st day of the 21 day cycle: 25mg, oral Q24H from the 1st to the 21st day of the 21 day cycle. The efficacy is evaluated every 2 months (CR, PR, SD, PD).

Drug: CDK4/6 inhibitor (Qilu),Trastuzumab (Hanquyou)

Interventions

CDK4/6 inhibitor (Qilu) have got the cFDA approval and Trastuzumab (Hanquyou) have few data on combination use, this two drugs need clinical treatment data

Also known as: Pertuzumab,Letrozole,exemestane
four-drug treatment group
