Cryoablation Combined With Tislelizumab Plus Lenvatinib In Previously Treated Gastric Cancer Liver Metastasis (CASTLE-09)
- Conditions
- Gastric Cancer Metastatic to Liver
- Interventions
- Registration Number
- NCT05893056
- Lead Sponsor
- Fudan University
- Brief Summary
The objective of this study is to evaluate the efficacy and safety of cryoablation combined with Tislelizumab plus Lenvatinib for patients with gastric cancer liver metastasis in the second-/third-Line setting.
- Detailed Description
Recent studies have suggested that local destruction of tumor tissue by cryoablation induced activation and maturation of dendritic cells and tumor-specific T cells by cross-presentation of tumor antigens. While pd-1 blocking antibody interferes with PD-1 mediated T-cell regulatory signaling. And combination of pd-1 blocking antibody plus lenvatinib showed increased ORR in many types of human cancers. Therefore, the objective of this study is to evaluate the efficacy and safety of cryoablation combined with Tislelizumab plus Lenvatinib in previously treated gastric cancer liver metastasis.

Group Intervention Description Cryoablation combined with Tislelizumab and lenvatinib Cryoablation Cryoablation treatment starts at day 0. Tislelizumab and Lenvatinib will be initiated on day 14 after cryoablation. Tislelizumab will be administered at 200 mg i.v. every 3 weeks until documented disease progression, development of unacceptable toxicity, participant request, or withdrawal of consent. Lenvatinib will be administered (bodyweight ≥ 60 kg, 12 mg; \< 60 kg, 8 mg) orally daily every 3 weeks until documented disease progression, development of unacceptable toxicity, participant request, or withdrawal of consent.

- Primary Outcome Measures
Name Time Method Objective Response Rate (ORR) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1 max 24 months ORR is defined as the percentage of participants who have a confirmed complete response (CR: disappearance of all target lesions) or partial response (PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters). Responses are according to RECIST 1.1 as assessed by investigator.
- Secondary Outcome Measures
Name Time Method Progression Free Survival (PFS) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1 max 24 months PFS is defined as the time from study treatment to disease progression or all-cause death as assessed by the investigator (whichever occurs first)
Duration of Response (DOR) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1 max 24 months DOR is defined as the time from first documented complete or partial response until disease progression, death from any cause, or censoring at date of last tumor assessment.
Overall survival (OS) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1 max 42 months OS is defined as the time from study treatment to the date of death of the subject, regardless of the cause of death
Number of participants with treatment-related adverse events as assessed by CTCAE v5.0 max 42 months An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants who experience at least one AE will be reported.
Disease control rate (DCR) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1 max 24 months DCR is defined as the proportion of patients with complete response (CR), partial response (PR) and stable disease (SD)
