简要总结
This prospective clinical trial will evaluate PET/CT and genomic liquid biopsy based biomarkers as predictors of clinical therapeutic response to immune-checkpoint inhibitor (ICI) therapy for patients with inoperable hepatocellular carcinoma (HCC). The primary objective of this diagnostic trial is to assess the accuracy of pre-treatment fluorine-18 (18F-) fluorocholine (FCH) PET/CT for predicting a lack of objective response (LOR) after 16 weeks of ICI therapy.
详细描述
This is a prospective open-label single-arm diagnostic clinical trial evaluating fluorine-18 fluorocholine (FCH) PET/CT and cell-free DNA mutation profiling (also referred to as genomic liquid biopsy) as diagnostic tools for predicting therapeutic response in advanced HCC patients receiving immune-checkpoint inhibitor (ICI) therapy. All enrolled subjects will undergo diagnostic testing with FCH PET/CT and genomic liquid biopsy before ICI treatment. A fluorine-18 fluorodeoxyglucose (FDG) PET/CT may also be performed before treatment and after 8 weeks if the pre-treatment FCH PET/CT shows low or heterogeneous tumor uptake. The accuracy of tumor biomarkers based on PET/CT and liquid biopsy for predicting therapeutic outcome and disease progression will be determined using objective clinical endpoints based on the radiographic classification of treatment response by RECIST v1.1 applied to CT or MRI performed after 16 weeks of treatment.

- •Under the care of a licensed medical oncologist
- •Life expectancy > 6 months
- •Deemed eligible for treatment with an immune checkpoint inhibitor agent based on the treating medical oncologist's assessment of previous treatment failure, clinical/performance/virology status, and liver/renal/hematologic function.

研究组 & 干预措施
Tested with Biomarkers
For this single arm study, all enrolled subjects will undergo diagnostic testing with FCH PET/CT and genomic liquid biopsy before treatment involving an immune checkpoint inhibitor agent. A fluorine-18 fluorodeoxyglucose (FDG) PET/CT may also be performed before treatment and after 8 weeks if the pre-treatment FCH PET/CT shows low or heterogeneous tumor uptake.
干预措施: Fluorine-18 fluorocholine (Combination Product)
结局指标

时间窗: 16 weeks
Lack of Objective Response defined after 16 weeks as meeting criteria for either Stable Disease or Progressive Disease based on RECIST v1.1
次要结局
- Disease Control(16 weeks)
- Objective Response(16 weeks)
