Brief summary
This is a Phase Ib/II, open-label, multi-center umbrella study evaluating the efficacy and safety of multiple targeted treatment in patients with refractory metastatic TNBC.The specific grouping of patients' depends on FUSCC 500+ gene panel testing and IHC subtype staining.
Detailed description
This is a Phase Ib/II, open-label, multi-center,umbrella study evaluating the efficacy and safety of multiple targeted treatment in patients with metastatic TNBC who had disease progression during or following standard treatment with chemotherapy(anthracyclines,taxanes,platinums, vinorelbine,capecitabine,and gemcitabine included).300-400 patients will be screened and eligible participants will enter different treatment arms according to their molecular subtype (IHC staining) and FUSCC 500+ gene panel testing results. These tests would be done on their rebiopsy tumor specimen. Specifically, as to TNBC molecular subtyping,FUSCC data identified the genomic aberrations that drive each TNBC subtype by applying an integrative analysis combining somatic mutation, copy number aberrations (CNAs) and gene expression profiles, which classified TNBC patients into four subtypes, namely luminal androgen receptor (LAR), immunomodulatory (IM), basal-like immune suppressed (BLIS), and mesenchymal-like (MES). Then, FUSCC conducted a IHC subtyping model to replace complex genomic sequencing, which have been validated in FUSCC cohort.FUSCC 500+ gene panel was developed combining public database(TCGA, METABRIC, 560WES, MSKCC-IMPACT ect.) and FUSCC private TNBC database.New treatment arms may be added and/or existing treatment arms may be closed during the course of the study on the basis of ongoing clinical efficacy and safety as well as the current treatments available.
Interventions
DRUGPyrotinib with Capecitabine
If patients were LAR subtype with HER2 gene activated mutation, she would receive pyrotinib(EGFR-TKI) 400mg qd and capecitabine 1000mg/m2 bid (d1-d14)
DRUGAR inhibitor combined with everolimus(B1) or CDK4/6 inhibitor(B2),or EZH2 inhibitor (B4)

Intervention model description
The refractory mTNBC participants will be classified into four subtypes based on immunohistochemistry tests namely luminal androgen receptor (LAR), immunomodulatory (IM), basal-like immune suppressed (BLIS), and mesenchymal (MES).Then according to gene sequencing outcomes, different subtypes would receive different targeted therapy (combined with chemotherapy in three treatment arms).
