Overview
The study aims to analyze blood samples from patients with advanced hepatocellular carcinoma who are receiving systemic treatment with immunotherapy. The objective is to determine whether treatment exposure leads to changes in the transcriptomic patterns of peripheral blood mononuclear cells (PBMCs), if these changes are associated with treatment response, and whether certain pre-treatment transcriptomic signatures can predict response to treatment. As an exploratory objective, PBMCs derived from patients exposed to immune checkpoint inhibitors will be co-cultured with their paired tumor cells in organoid cultures. This aims to assess whether these preclinical 3D models correlate with clinical outcomes.
Detailed description
The primary pivotal objective of the study is to analyse the single cell transcriptome of peripheral blood mononuclear cells (PBMCs) in patients with HCC treated with immunotherapy to define if treatment exposure determines transcriptomic pattern changes and if some of these changes are associated with treatment response.
The secondary objective of the study is to investigate if some pre-treatment transcriptome signature of PBMCs is predictive of response and long-lasting response to treatment.
As an exploratory objective, the study investigators will analyse the interaction between patients' peripheral immune cells previously exposed to immune check-point inhibitors and their paired tumour cells in the organoid cultures.
Primary outcome measures
- Analysis of the single cell profiling of peripheral blood mononuclear cells in patients with HCC treated with immunotherapy pre-therapy (T0) and the 3 months post-therapy (T3) to define if a difference between the two time points exists. [Time frame: From enrollment untill 3 months after treatment start, (up to 120 days from study inclusion)]
Secondary outcome measures (2)
- Correlation between transcriptome signature at baseline and treatment outcomes. [Time frame: From enrollment to the time of best response to treatment, up to 24 months from enrollement]
- Correlation between baseline gene clusters and treatment responses [Time frame: From enrollment to the time of best response, up to 24 months from enrollment]
