Liver Cancer and Immunotherapy in the Liquid Biopsy Era

Condition(s) studied

Investigational drug(s) / intervention(s)

Liquid Biopsy: 30mL blood sample: * 1 x 10mL CellSave tube specifically designed for the collection and preservation of CTCs for CellSearch® analysis * 1 EDTA tube for PBMCs isolation and circulating immune cells study (5mL), * 2 EDTA tubes and 1 dry tube (15mL) for the preparation of the biobank (serum, plasma and cell).

Study summary

The goal of this prospective clinical trial is to identify a predictive biomarker in patients with advanced HCC (stage B and C) using a combinatorial approach of the liquid biopsy.

The main questions it aims to answer are:

* Is multi-omic liquid biopsy approach able to identify a strong predictive biomarker of immunotherapy efficiency?
* Is there a correlation between tissue biopsy (PD-L1 tissue level of expression) and liquid biopsy (detection of CTC expressing PD-L1) in HCC patients?

Participants blood will be collected at several time points.

Eligibility

Primary outcome measure(s)

• Percentage of patients with CTCs-PD-L1+ by CellSearch® technique — At inclusion
  A CTC is being defined as: EpCAM(+)/PanCK(+)/Dapi(+)/CD45(-). The PD-L1 status will be observed only on these cells. CTC-PD-L1- = 0 vs CTC-PD-L1+ ≥1
