This is a single-center Ib / II study of triple targeted drug combination (endocrine therapy,novel HER2-targeted small molecule inhibitor pyrotinib and CDK4/6 inhibitor dalpiciclib(SHR6390) ) as a first or second line of therapy in patients with relapsed/metastatic hormone receptor positive and HER2-positive breast cancer.


This is a single-center, single arm, open-label, run-in phase Ib / roll-over phase II study of endocrine therapy in combination with novel human epidermal growth factor receptor-2(HER2)-targeted tyrosine kinase Inhibitor pyrotinib and cyclin-dependent kinase 4/6(CDK4/6) Inhibitor dalpiciclib(SHR6390) in subjects with hormone receptor(HR)+/HER2+ relapsed or metastatic breast cancer. The study will enroll natural postmenopausal women, or women who have undergone bilateral oophorectomy.The phase Ib part of the study will determine safety and tolerability of the combination of endocrine therapy, pyrotinib and dalpiciclib to define that appropriate dose of dalpiciclib for phase II.Data from phase Ib showed the triplet of pyrotinib, dalpiciclib, andendocrine therapy had an acceptable safety profile and encouraging efficacy, potentially offering a chemotherapy-sparing treatment option for patients with HER2-positive/HR-positive MBC.Once the recommended regimen has been identified, subjects with the selected tumor type will be enrolled into expansion cohorts for the purpose of assessing efficacy and safety of the combination treatment.

Inclusion Criteria

Subjects voluntarily joined the study, signed informed consent, and had good compliance
Postmenopausal or premenopausal perimenopausal female patients aged ≥ 18 years and ≤ 75 years old,Meet one of the following
Previous bilateral oophorectomy, or age ≥ 60 years; or Age <60, natural postmenopausal state (defined as regular months for at least 12 consecutive months After spontaneous cessation and no other pathological or physiological reasons),E2 and FSH in menopause Post-level; or
HER2 positivity is defined by standard of 3+ staining by immunohistochemical staining (IHC) or positive for in situ hybridization (ISH)
Pre-menopausal or perimenopausal female patients can also be included, but must be willing to receive treatment with LHRH agonists
Patients with HR+/HER2+ recurrent or metastatic breast cancer confirmed by
Local recurrence needs to be confirmed by the physician that is unresectable
Estrogen receptor(ER) or Progesterone receptor(PR) positive is defined as the percentage of cells positive for ER or PR expression ≥ 1%
Prior treatment
Previously received no more than 1 prior lines of systemic treatment with trastuzumab regimen for repetitive metastatic diabetes [including anti-HER2 ADC, subsequent meaning is the same]
At least one extracranial measurable lesion according to Response Evaluation Criteria
in Solid Tumors (RECIST) criteria version 1.1
The first-line treatment fails with the trastuzumab-containing regimen, or the trastuzumab-containing regimen recurs during the adjuvant treatment or relapses within 1 year after the adjuvant treatment ends, the follow-up treatment will be included as the second-line anti-HER2 treatment
The early stage includes trastuzumab-containing regimen treatment, or trastuzumab-containing regimen that relapses more than 1 year after the end of adjuvant treatment, and subsequent treatment is included as the first-line anti-HER2 treatment
Adequate function of major organs meets the following requirements (no blood components and cell growth factors have been used within 14 days before randomization)
Have not received anti-HER2 TKI treatment before or received but did not prove
that the treatment failed
Past endocrine therapy has not proven resistance to aromatase inhibitors (definition of resistance: recurrence during or within 1 year after treatment with adjuvant aromatase inhibitors, received aromatase inhibitors in the recurrence and metastasis stage and disease progression), follow-up Letrozole is selected for endocrine therapy. Past endocrine therapy has aromatase inhibitor resistance, and follow-up endocrine therapy is fulvestrant

Meningeal metastasis or active brain parenchymal metastasis. Patients with clinically stable brain parenchymal metastases can be included, including asymptomatic brain metastases that have not received local treatment; or patients who have previously received central nervous system metastasis therapy (radiotherapy or surgery), if imaging confirms that stability has been maintained for at least 4 weeks , and have stopped symptomatic treatment (including hormones and mannitol, etc.) for more than 2 weeks

Have undergone major surgical procedures or significant trauma within 4 weeks prior to randomization, or are expected to undergo major surgery
Pregnant women, lactating female, or women of childbearing age who are unwilling to take effective contraceptive measures
Have a history of allergies to the drug components of this regimen
Patients with active HBV and HCV infection; stable hepatitis B after drug treatment (HBV virus copy number is higher than the upper limit of reference value) and cured hepatitis C patients (HCV virus copy number exceeds the lower limit of detection method)
History of immunodeficiency, including HIV positive, or other acquired or congenital immunodeficiency disease, history of organ transplantation
Female patients who are pregnancy, lactation or women who are of childbearing potential tested positive in baseline pregnancy test
Childbearing female who refuse to accept any contraception practice
Determined by the physician, any serious coexisting disease might be harmful to the patient's safety or avoid the patients from accomplishing the treatment(e.g serious hypertension, diabetes, thyroid dysfunction,active infection etc.)
