This study includes single agent/combination dose exploration study and the phase II study. The primary purpose of the dose exploration study is to determine the maximum tolerated dose(MTD)/recommended phase II dose(RP2D) of XZP-3287 and assess its safety and preliminary efficacy in solid tumor patients. The phase II study aims to explore the efficacy and safety profiles of XZP-3287 as a single- agent in hormone receptor(HR) positive, human epidermal growth factor receptor 2(HER2) negative advanced breast cancer.

Single agent and combination dose exploration study:AE evaluation
AEs as characterized by frequency and severity (as graded by National Cancer Institute Common Terminology Criteria for Adverse Events \[NCI CTCAE\] version 4.03 for single agent dose exploration study and CTCAE 5.0 for combination exploration study)
Up to 30 days after the end of treatment
The phase II study:Objective response rate (ORR) assessed by Independent Review Committee (IRC)
ORR is the percentage of participants with a best overall response (BOR) of complete response (CR) or partial response (PR) as defined by RECIST v1.1.
From baseline to the date of first documentation of progression or death , whichever came first, assessed approximately up to 2 years after the last entered participant
Progression free survival (PFS)
From baseline to the date of first documentation of progression or death, whichever came first, assessed approximately up to 2 years after the last entered participant
Overall survival (OS)
From baseline to the death from any cause, assessed approximately up to 2 years after the last entered participant
Duration of response (DoR)
From baseline to the date of first documentation of progression or death, whichever came first, assessed approximately up to 2 years after the last entered participant
Disease control rate (DCR)
From baseline to the date of first documentation of progression or death, whichever came first, assessed approximately up to 2 years after the last entered participant
Clinical benefit rate (CBR)
From baseline to the date of first documentation of progression or death, whichever came first, assessed approximately up to 2 years after the last entered participant
To determine the MTD and RP2D of XZP-3287
To determine the RP2D of XZP-3287 combined with endocrine therapy
To determine the efficacy and safety profiles of XZP-3287 as a single- agent in hormone receptor (HR) positive, human epidermal growth factor receptor 2 (HER2) negative advanced breast cancer
* 20-560 mg QD, oral * 240-480 mg BID, oral
XZP-3287: 360 mg BID, oral; Letrozole: 2.5 mg QD, oral; Anastrozole: 1 mg QD, oral; Fulvestrant: 500 mg intramuscular injection on C1D1, C1D15, the first day of each subsequent cycle (28 days a cycle)
