The treatment period mainly includes:

1. Injection of Paclitaxel (Albumin-bound) at a dose of 260mg/m\^2 administered intravenously every 3 weeks as one treatment cycle, for 6 cycles.
2. Injection of Carboplatin (AUC=5) administered intravenously every 3 weeks as one treatment cycle, for 6 cycles.
3. Injection of Camrelizumab at a dose of 200mg administered intravenously every 3 weeks as one treatment cycle, for 6 cycles.
4. Radiation therapy: Not mandatory.

Maintainance therapy period mainly includes:

1. Injection of Camrelizumab at a dose of 200mg administered intravenously every 3 weeks as one treatment cycle until disease progression, intolerable toxicity, death, or up to a maximum of 2 years.
2. Oral administration of Fluzoparib capsules at a dose of 150mg, once in the morning and once in the evening until disease progression, intolerable toxicity, death, or up to a maximum of 2 years.

Treatment period mainly include:

1. Injection of Paclitaxel (Albumin-bound) at a dose of 260mg/m\^2 administered intravenously every 3 weeks as one treatment cycle, for a total of 6 cycles.

This study is an open-label Phase II randomized controlled trial designed to evaluate the safety and efficacy of camrelizumab plus fluzoparib maintenance therapy in patients with recurrent or metastatic TP-53 mutated Endometrial Cancer. The study will also explore the prevalence of homologous recombination reficiency in Chinese patients with TP-53 mutated endometrial cancer and its therapeutic significance.

The treatment of recurrent or metastatic endometrial carcinoma (R/M-EC) has entered the era of molecular marker oriented precision therapy. Meanwhile, several large multicenter Phase III RCT studies have been conducted, such as NRG-GY018, RUBY, DUO-E and AtTEnd, and suggested that chemotherapy combined with immunotherapy could significantly improve the prognosis of R/M-EC. Unfortunately, the efficacy of ICBs in Asian R/M-EC population is not obvious, with small size.

On the other hand, up to 63% of patients with R/M-EC have TP-53 gene mutations (TP53mut). And the efficacy of chemotherapy combined with immunotherapy in thse patients is controversial. In the RUBY study, TC combined with Dostarlimab reduced the risk of death in patients with TP53mut-R/M-EC by 59 percent. However, in the DUO-E study, chemotherapy combined with Durvalumab failed to improve serous -EC in 154 patients (approximately 92% TP53mut). Therefore, how to optimize the strategy of chemotherapy combined with immunotherapy in TP53mut-R/M-EC is urgently needed.

Considering TP53mut-EC patients with tumor local T-lymph Cell infiltration and PD-L1 expression were significantly higher than those of TP-53 gene wild type (TP53wt) patients. It was also suggested that ICB and PARPi had a good synergistic effect. The DUO-E study revealed the combination of Durvalumab and Olaparib maintenance therapy significantly improves the prognosis of serous EC.

Therefore, as an investigator-initiated open-label Phase II randomized controlled study, the study will include 117 patients with TP53mut-R/M-EC, and randomly divided 2:1 into experimental group and control group to evaluate the safety and efficacy of camrelizumab plus fluzoparib maintenance therapy in patients with recurrent or metastatic TP-53 mutated Endometrial Cancer. The study will also explore the prevalence of homologous recombination reficiency in Chinese patients with TP-53 mutated endometrial cancer and its therapeutic significance.
