HBV Serum Biomarkers Workshop

ICE-HBV is organizing an virtual and interactive workshop on HBV biomarkers endorsed by the International HBV Meeting. The event is aimed at scientists, clinicians, pharmaceutical and diagnostic industry representatives.  The workshop, chaired by Anna Kramvis and Peter Revill, is put together by the ICE-HBV serum biomarkers working group. Both classic and future biomarkers will be discussed. The workshop will lead to a consensus statement on promising serum biomarkers. 

The workshop will be divided in two sessions, held on Monday Oct 5 and Monday Oct 12, 2020, via Zoom. Both sessions will start at 12PM GMT, go for approximately 2.5 hours each, and will be recorded.

Free registration is open here.

Background & Objectives:

Functional cure, the loss of HBV surface antigen is the major goal of many HBV cure strategies, using direct acting antivirals and anti-HBV immune-stimulating responses. On the other hand, complete cure involves the elimination or inactivation of the covalently closed circular DNA (cccDNA) reservoir.  As new therapies are developed and tested, there is an urgent need for serum biomarkers that can:

  • accurately correlate with cccDNA expression in the liver,
  • predict HBsAg loss,
  • measure stimulation of host antiviral immune responses
  • screen HBV carriers in order to identify those at high risk of developing hepatocellular carcinoma

Although a number of alternative HBV serum biomarkers have been proposed, including HBV RNA and core related antigen, their clinical relevance, in all settings of chronic HBV infection, has yet to be resolved.

In this workshop, a range of experts will discuss the latest advances and identify knowledge gaps in our understanding of serum biomarkers.  They will discuss challenges that need to be overcome to ensure the utility of various biomarkers in the clinic and for screening new antiviral therapies. Presentations will be complemented by two in-depth discussion panels that will debate these challenges and propose a way forward.
