Inclusion criteria
✓. Age ≥18 years old and ≤75 years old, female, voluntarily sign informed consent;
✓. The patient must have one of the following types of endometrial cancer: a) Newly diagnosed stage III disease (lesions assessed as measurable according to RECIST 1.1 after surgery or diagnostic biopsy), b) newly diagnosed stage IV disease (small lesions assessed as measurable or unmeasurable according to RECIST 1.1 after surgery or diagnostic biopsy, and truly unmeasurable lesions need to be excluded, (such as ascites, pleural effusion, etc.) c) recurrent diseases (small foci assessed as measurable or unmeasurable according to RECIST 1.1, truly unmeasurable foci, such as ascites, pleural effusion, etc.),
✓. There is little likelihood of cure with surgery/radiotherapy alone or in combination, or surgery or radiotherapy cannot be tolerated;
✓. Have not received first-line systemic anticancer therapy. Prior chemotherapy is permissible only for patients with recurrent disease if it is received under adjuvant conditions (as part of prior/adjuvant anticancer therapy) and the interval between the last dose of chemotherapy and the date of subsequent recurrence is at least 6 months;
✓. Subjects should meet the requirements of mismatch repair protein deficiency (dMMR) detected by the central laboratory of tumor specimen. Subjects should provide sufficient paraffin embedded (FFPE) specimens or sections (6 recommended, no less than 3) and be willing to undergo tumor tissue biopsies if needed for MMR status detection. The archived tissue must be a representative tumor specimen less than three years old, or an unstained continuous section of newly cut FFPE tumor tissue within six months, and the relevant pathological report of the above specimen must be provided. Fresh tissue specimens can be harvested by surgical excision and biopsy. Do not accept fine needle puncture and liquid based cytology (TCT) samples (i.e., samples that lack complete tissue structure and only provide cell suspension and/or cell smear); Decalcified bone metastatic tumor tissue specimens are not accepted;

7
Progression Free Survival
Timeframe: Tumor imaging assessments will be performed once every 6 (±7) days during the screening period, once every 6 (±7) days after initial dosing to 25 weeks, and once every 9 (±7) weeks，assessed up to 1 year，the screening period is 28 days
✓. Expected survival assessed by investigators ≥12 weeks;
✓. The physical status score of the American Eastern Cancer Consortium (ECOG) is required to be 0 \~1 points;
✓. Fertile female patients must have a negative serological pregnancy test within 7 days prior to the first dosing and be willing to use effective birth control/contraception to prevent pregnancy during the study period up to 6 months after the last dosing of the study. Postmenopausal women must have amenorrhea for at least 12 months before they are considered infertile.
Exclusion criteria
✕. Have endometrial leiomyosarcoma or other high-grade sarcoma, or endometrial stromal sarcoma.
✕. Pregnant and lactating women;
✕. Radical radiation therapy was received within 3 months before the first administration of the study drug. Note: Palliative radiotherapy for bone or superficial lesions is permitted, the course of treatment is according to local standards and has ended 14 days before the first dose. Radiotherapy that covers more than 30% of the bone marrow area within 28 days prior to initial dosing is not permitted; Received chemotherapy drugs for radiosensitization within 14 days prior to initial administration; Within 14 days prior to the first administration of the drug, have received the NMPA-approved Chinese patent medicine or treatment clearly with anti-tumor related functions, or the medical record clearly recorded in the anti-tumor purpose of Chinese herbal therapy;
✕. are participating in the treatment stage of other clinical studies, or plan to start this study treatment less than 14 days from the end of drug treatment of the previous clinical study;
✕. Have received live/attenuated vaccines and mRNA vaccines within 4 weeks prior to screening or plan to receive live/attenuated vaccines and mrna vaccines during the study period;
✕. Previously received immune checkpoint inhibitors (such as anti-PD-1 antibodies, anti-PD-L1 antibodies, anti-CTLA-4 antibodies, etc.) or immunocostimulatory factors (such as antibodies against ICOS, CD40, CD137, GITR, OX40 targets, etc.) and other treatments targeting tumor immune mechanisms;
✕. Before the first administration of antitumor therapy, there were still more than grade 1 aes (based on CTCAE v5.0) (except for alopecia, fatigue and other AE that could not be restored to grade 1 or less and would remain in a stable state for a long time as judged by researchers based on clinical conditions, and grade 2 peripheral neurotoxicity. Except for stable hypothyroidism after hormone replacement therapy); Those who had a history of ≥ grade 3 irAE or had discontinued immunotherapy for any grade of irAE;
✕. Active pia meningeal disease or poorly controlled brain metastases. Patients with suspected or confirmed BMS were admitted if they were asymptomatic, had stable disease on imaging findings ≥28 days prior to first administration of the study drug, and did not require treatment (such as radiation therapy, surgery, or corticosteroid therapy) to control symptoms of BMS for 28 days prior to first administration of the study drug.
