Brief Summary:
This is a single-center, single-arm phase Ib / II clinical trial, which was included with two phase. The main purpose of the phase Ib part was to determine the dose-limiting toxicity ( DLT ), maximum tolerated dose ( MTD ), and recommended dose ( RP2D ) of Fluzoparib combined with Dalpiciclib in patients with locally advanced or metastatic sarcoma. The phase II part is mainly to observe the efficacy and safety of Fluzoparib combined with Dalpiciclib.

Condition or disease Intervention/treatment Phase
Sarcoma Drug: Fluzoparib+ Dalpiciclib Phase 2

Detailed Description:
The overall prognosis for patients with soft tissue sarcoma is not ideal, with a median survival rate of only about 20 months for patients diagnosed with metastasis. Soft tissue sarcomas (more than 50%) are deficient in HRR due to the presence of BRCA mutations in the tumor. When patients with BRCA1/2 gene mutation are treated with PARP inhibitors, a damage to DNA single strand breaks can be observed, and cannot be repaired promptly, resulting in tumor cell death. In addition, selective inhibition of CDK4/6 was found to inhibit the growth of sarcoma cells and induce their apoptosis. For example, inhibition of CDK4 decrease the proliferation of osteosarcoma cells and promote their apoptosis in vitro, and targeted CDK6 inhibition can inhibit the proliferation, invasion and migration of Ewing's sarcoma cells. Therefore, in this study, Dalpicicli, a CDK4/6 inhibitor, and Fluzoparib, a PARP inhibitor, were used in the treatment of advanced and metastatic soft tissue sarcoma, so as to explore the efficacy and safety of the combined regimen.

Primary Outcome Measures :
  1. Recommended Phase II dose (RP2D) [ Time Frame: from 4 weeks to 20 weeks after the first dose of Fluzoparib and Dalpiciclib combination therapy ]
    Determination of Recommended Phase II dose (RP2D) of Escalating Dose of Fluzoparib with Dalpiciclib.

  2. dose limiting toxicity (DLT). [ Time Frame: from 4 weeks to 20 weeks after the first dose of Fluzoparib and Dalpiciclib combination therapy ]
    Observe the incidence of dose limiting toxicity (DLT).

  3. maximize toxicity dose(MTD) [ Time Frame: from 4 weeks to 20 weeks after the first dose of Fluzoparib and Dalpiciclib combination therapy ]
    Determination of maximize toxicity dose(MTD)

  4. Objective Response Rate(ORR) as Assessed by the Investigator according to RECIST v1.1 [ Time Frame: up to approximately 2 Years ]
    Objective Response Rate(CR+PR), defined as best overall response (complete or partial response) across all assessment time points, determined using RECIST v1.1 criteria.

Secondary Outcome Measures :
  1. Disease control rate(DCR) [ Time Frame: Up to approximately 2 Years ]
    Disease control rate(DCR) is defined DCR=CR+PR+SD/CR+PR+SD+PD, which reflects the ratio of patients whose tumors shrank or remained stable for a certain period of time.

  2. Duration of remisson(DoR) [ Time Frame: Up to approximately 2 Years ]
    Duration of remisson(DoR) is defined as the time interval from the beginning of the response ( when CR or PR is first determined ) to progression or death ( whichever occurs first ).

  3. Progression free surviral(PFS) [ Time Frame: Up to approximately 2 Years ]
    Progression Free Survival is defined as from the date of first administration to the date of disease progression or death, no matter which is earlier.

  4. Overall survial(OS) [ Time Frame: Up to approximately 2 Years ]
    Overall survial(OS) is defined as from the date of first administration to the date of death.

  5. Incidence of Adverse Events [safety and tolerability] [ Time Frame: From the first administration to 30 days after the last administration ]
    Adverse events defined according to Common Terminology for Adverse Events (CTCAE) v5.0
