About this study

The objectives of the study are to determine the impact of interferon-free treatment for the hepatitis C virus (HCV) on peripheral blood immune cell phenotype and soluble immune-related proteins in blood, while controlling for genetic polymorphisms known to impact HCV-related immune responses, and to determine the impact of the therapy on the emergence of drug-resistant HCV. The study design is informed by the researchers recent investigations of patients receiving HCV treatment. About 4% of patients who had not undergone liver transplantation experienced hepatic decompensating or another serious event. There were several cases of bacterial infection and two cases with elevated markers of autoimmune processes. These events suggest that treatment altered immune responses. About 25% of patients who had undergone liver transplantation experienced hepatic decompensating or another serious adverse event. The long term goal is to understand the pathophysiology of these complications and determine whether HCV treatment can cause an immune reconstitution syndrome in susceptible patients, while improving antimicrobial defenses in others

The objectives of the study are to determine the impact of interferon-free treatment for the hepatitis C virus (HCV) on peripheral blood immune cell phenotype and soluble immune-related proteins in blood, while controlling for genetic polymorphisms known to impact HCV-related immune responses, and to determine the impact of the therapy on the emergence of drug-resistant HCV. The study design is informed by the researchers' recent investigations of patients receiving HCV treatment. About 4% of patients who had not undergone liver transplantation experienced hepatic decompensation or another serious event. There were several cases of bacterial infection and two cases with elevated markers of autoimmune processes. These events suggest that treatment altered immune responses. About 25% of patients who had undergone liver transplantation experienced hepatic decompensation or another serious adverse event. The long term goal is to understand the pathophysiology of these complications and determine whether HCV treatment can cause an immune reconstitution syndrome in susceptible patients, while improving antimicrobial defenses in others The main questions/objectives to be addressed are (1) to determine the effect of HCV treatment on the profile of immune cells in blood as assessed by cytometry time of flight (CyTOF) multiparameter analysis, while controlling for genetic polymorphisms known to be associated with HCV-related immune responses and, (2) to determine the effect of treatment on factors/proteins in blood that may be related to immunity and inflammation.

Background: New treatments for HCV are significantly more effective than past treatments. They utilize direct acting antiviral drugs (DAA) and many do not include interferon. The goal of treatment is to achieve a sustained virological response (SVR). An SVR is indicated by the absence of detectable HCV RNA in blood 12 weeks after the end of treatment (EOT); this is called SVR12. The researchers recently investigated outcomes of 514 non-liver transplant (LT) patients and 43 LT patients who initiated treatment between Dec 2013 and June 2014. Several patients developed increased levels of markers of autoimmune processes and/or experienced a bacterial infection. Investigators at other institutions recently reported evidence that DAA treatment enhances immune cell activation. The combination of the investigators' observations and the observations of others indicates that a detailed investigation is needed to understand the events leading to increased immune cell activity and to determine the factors that may increase the risk of serious adverse events.

Questions about this trial

What is this clinical trial studying?

An observational study of Hepatitis C and HCV, run by Icahn School of Medicine at Mount Sinai at 1 site in United States.

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 11 inclusion and 0 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 18 Jan 2018. 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 United States. 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?

cytometry time of flight (CyTOF) (time frame: up to week 14). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 Jan 2018.
