Brief summary
This study is a prospective, single-center, open-label, umbrella-shaped phase II clinical study for patients with HR+/HER2- endocrine-resistant advanced breast cancer.
Detailed description
Seven precision treatment cohorts, which targeting NF1 mutation, gBRCA mutation,HER2 mutation, FDGFRb mutation PAM pathway mutations, CD8 and AR, as long as an epigenetic therapy cohort and a combined immunization cohort were initially set up based on gene expression profiles and molecular pathways. The main purpose is to screen valuable treatment cohorts and prepare for subsequent randomized controlled phase III clinical studies with larger sample size.
Interventions
MEK1/2 inhibitor
Multi-target tyrosine kinase inhibitor
PARP inhibitor
HER1 / HER2 receptor tyrosine kinase inhibitor
In Arm III, if the patient had not previously used capecitabine,she would receive pyrotinib and capecitabine, if the patients have previously used capecitabine, she would only used pyrotinib as a single agent.
PD-1 antibody
mTOR inhibitor
Albumin bound paclitaxel
EZH2 inhibitor
AR inhibitor
CDK4/6 inhibitor
anti-PD-L1/TGF-βRII bifunctional fusion protein
Fulvestrant
aromatase inhibitor
Bevacizumab

Eligibility
Inclusion criteria
* Females ≥18 years old; * Histologically confirmed HR + / HER2- invasive breast cancer (specific definition: immunohistochemical detection of ER\> 10% tumor cell positive is defined as ER positive, PR\> 10% tumor cell positive is defined as PR positive, ER and / or PR Positive is defined as HR positive; HER2 0-1 + or HER2 is ++ but negative followed by FISH detection, no amplification, defined as HER2 negative); * Locally advanced breast cancer (incapable of radical local treatment) or recurrent metastatic breast cancer; * Patients with HR+/HER2- advanced breast cancer who were previously treated with CDK4 / 6 inhibitor except for Arm 5E-5F; * Measurable disease according to Response Evaluation Criteria in Solid Tumors v1.1 (RECIST v1.1) * Has adequate bone marrow function: absolute neutrophil count \> 1.5x10ˆ9 /L; platelet count \> 75x10ˆ9 /L, hemoglobin \> 9g/dL; * Has adequate liver function: alanine aminotransferase (ALT) ≤1.5×upper limit of normal (ULN), aspartate aminotransferase (AST) ≤3×ULN, alkaline phosphatase (AKP) ≤3×ULN, total bilirubin (TBIL) ≤ 1.5×ULN. * Has adequate kidney function: serum creatinine ≤1×ULN.Endogenous creatinine clearance\> 50 ml / min (Cockcroft-Gault formula); * Did not receive radiation, molecular targeted therapy or surgery within 3 weeks before the study began, and has recovered from the acute toxicity of previous treatment (if surgery, the wound has completely healed); no peripheral neuropathy or first degree peripheral neurotoxicity ; * ECOG score ≤ 2 and life expectancy ≥ 3 months; * Participants voluntarily joined the study, has signed informed consent before any trial related activities are conducted, has good compliance and has agreed to follow-up.
Exclusion criteria
* Treatment with chemotherapy, radiotherapy, immunotherapy or surgery (outpatient clinic surgery excluded)within3 weeks prior to initiation of study treatment(bisphosphonates can be used for bone metastasis); * Symptomatic, untreated, or actively progressing CNS metastases(glucocorticoids or mannitol needed to control symptoms); * Significant cardiovascular disease(including congestive heart failure, angina pectoris, myocardial infarction or ventricular arrhythmia in the last 6 months); * Grade ≥ 1 adverse reactions that are ongoing due to previous treatment. Exceptions to this are hair loss or the investigator's opinion should not be ruled out. Such cases should be clearly documented in the investigator's notes; * Is pregnant or breast feeding; * Malignant tumors in the past five years (except cured skin basal cell carcinoma and cervical carcinoma in situ).
