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.
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.
