About this study

Official title: Hepatitis C Virus Particles-bound Human Proteins : Identification in Clinical Samples and Implication in the Viral Life Cycle

The emergence of hepatocellular carcinoma (HCC) has prompted a search for a thorough understanding of the biology of one of its major causative agents, the hepatitis C virus (HCV). HCV particles acquire via budding and encapsidation cellular proteins. There is mounting evidence on several viral species that virion-bound proteins are prone to be involved either at the replication, budding/egress or entry/release steps of the viral cycle.

Identifying such targets may yield ideal candidates for gaining insight on the dependence of HCV upon a restricted subset of host proteins, therefore providing refined sets of genetically stable targets for therapy. This project's goals are to set up adequate conditions for robust and reproducible purification of HCV virions in clinical samples, followed by the identification of their HCV-bound host proteins and the characterization of their functions. Proteomics profiling of HCV particles purified from clinical samples will be overlaid with proteins identified and characterized in cell culture grown HCV particles during my post-doctoral training, using clinical biomarker discovery grade criteria. Targets identified in both samples sets will be subjected to in vitro investigations using HCV-replicating cells. Conventional biochemical and imaging methods will be used in order to: (i) ascertain their physical association with HCV virions; (ii) define the modalities of their interaction with HCV proteins; (iii) decipher the topology and subcellular localization of their association with HCV proteins and virions; (iv) quantitatively assess their functional involvement in particle budding, egress or secretion and infectivity. A candidate that yielded satisfactory results in these experiments will be disclosed and further investigated at the level of structural biology, in collaborative research programs.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Qualitative identification (unit used: Protein Prophet score) of a given virion-bound protein in purified virions preparations

    Protein prophet scores allow one to estimate the robustness of identification of a given protein in MS approaches.

    Measured: One to two years after mass spectrometry identification of the candidate

  2. Quantitative evaluation of its implication in viral morphogenesis (unit used: TCID50).

    TCID50 units are infectivity units routinely used in HCV research for viral infectivity quantification.

    Measured: One to two years after mass spectrometry identification of the candidate

  3. Quantitative evaluation of viral entry (unit used: HCV RNA /GUS mRNA copy ratios).

    HCV RNA /GUS mRNA copy ratios are derived from the 2^delta(delta Ct) method.

    Measured: One to two years after mass spectrometry identification of the candidate

Secondary outcomes (1)
  1. Comparison of clinical virions datasets with in vitro grown virions datasets

    Proteins identified from viral particles purified from clinical samples will be compared to proteins identified in viral particles from cells of human hepatocarcinoma (Huh7.5) infected with HCV and from which data are published.

    Measured: One to two years after mass spectrometry identification of the candidate

Questions about this trial

What is this clinical trial studying?

A study testing blood draw of 150ml, twice in people with Hepatitis C, run by Hospices Civils de Lyon at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Qualitative identification (unit used: Protein Prophet score) of a given virion-bound protein in purified virions preparations (time frame: One to two years after mass spectrometry identification of the candidate). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02795403, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Sep 2025.
