简要总结
The goal of this study is to determine efficacy and safety of AK104 combined with I-125 brachytherapy for recurrent or metastatic cervical cancer.
This is an open-label, single-center, observational study of AK104 with Iodine-125 brachytherapy in the treatment of recurrent or metastatic cervical cancer. 18 eligible patients will receive Iodine-125 brachytherapy (single implantation, half-life of 60 days, 99% of total dose given after 90 days), followed by AK104 treatment (6mg/kg Q2W) starting within 1 week of particle implantation, for a total of 6 cycles or until disease progression, intolerable toxicity, investigator decision, withdrawal of informed consent, death, or other reasons as specified in the protocol.
详细描述
Study Title AK104 combined with Iodine-125 brachytherapy in the Treatment of Recurrent or Metastatic Cervical Cancer
Study Objectives Primary Objective To explore the effectiveness of AK104 in combination with Iodine-125 brachytherapy in the treatment of recurrent or metastatic cervical cancer.
Secondary Objective To explore the safety of AK104 in combination with Iodine-125 brachytherapy in the treatment of recurrent or metastatic cervical cancer.
Study Endpoints Primary Endpoint Objective response rate (ORR) based on RECIST 1.1 evaluation.
Secondary Endpoints Disease control rate (DCR), progression-free survival (PFS), and 3-year overall survival rate (OS) based on RECIST 1.1 evaluation.

排除标准
- •Potential subjects who meet any of the following criteria should be excluded from the study:
- •History of using anti-PD-1 antibodies, anti-CTLA-4 antibodies, TCR-T, CAR-T, or other immunotherapy within the past 4 weeks before the first dose, or participation in other anti-tumor drug clinical trials within the past 4 weeks before the first dose, or planned use of attenuated live vaccines during the study period.
