Creating a cohort to study viral RNAs as a new biomarker for hepatitis B cure.

Creation of a Cohort for the Quantitation and Characterization of Circulating Viral RNAs as a New Biomarker of Hepatitis B Functional Cure.

Observational Hospices Civils de Lyon · NCT03825458

This study is trying to see if measuring certain viral RNAs in blood samples can help find a new way to tell if people with hepatitis B are getting closer to a cure.

What this trial studies

This project, known as the CirB-RNA cohort, aims to establish a biological collection of samples and associated clinical data from patients with hepatitis B infection. The focus is on characterizing and quantifying circulating viral RNAs, which may serve as a new biomarker for achieving a functional cure of hepatitis B. Blood samples will be collected from eligible patients during their medical appointments to support this research. The study includes both adults and children over six years old who meet specific criteria related to hepatitis B.

Who should consider this trial

Good fit: Ideal candidates include adults and children over six years old with acute or chronic hepatitis B or those who have experienced HBsAg loss.

Not a fit: Patients currently participating in interventional trials for hepatitis B treatments may not benefit from this observational study.

Why it matters

Potential benefit: If successful, this study could lead to the identification of a new biomarker that helps in monitoring and achieving a functional cure for hepatitis B.

How similar studies have performed: While the approach of using circulating viral RNAs as biomarkers is innovative, similar studies have not been widely reported, making this a potentially novel investigation.
