Introduction
Treatment challenges highlight need for new management approach
 Treating hepatitis B virus (HBV) infection continues to be a
challenge for physicians due to
– Complications arising from chronic HBV (CHB)
– The increasing number of available therapeutic options
 Treatment guidelines recognize the importance of monitoring and
evaluation of treatment response; however, a standard
on-treatment management approach does not exist
 To establish a new treatment paradigm, we should ask
– Does long-term suppression of HBV replication achieve the goals of
treatment in CHB?
– Can the degree of on-treatment viral suppression predict outcomes?
– Does profound, early viral suppression at week 24 predict clinical
outcomes?
– Can a Roadmap concept help achieve the goals of treatment in CHB?

Presentation Objectives
 To explore the association between persistent viraemia and
hepatitis disease progression
 To assess the relationship between the degree of viral
suppression and clinical outcome
 To assess the role of early and effective viral load reduction and
the association with clinical outcomes*
 To review an on-treatment management strategy – the roadmap
concept – that may offer a valuable opportunity for enhanced
treatment response

Evidence for Association Between HBV DNA
and Clinical Outcomes
 Natural history studies demonstrate
– Lower HBV DNA levels are associated with better underlying
histology
– High HBV DNA may be an independent predictor for cirrhosis
and HCC
– Sustained suppression of HBV may reduce long-term risk of
cirrhosis and HCC
 Hypothesis needs to be proven prospectively

On-Treatment Roadmap
Concept
Potential Foundation for Building a CHB
Therapeutic Roadmap
On-treatnent early virological response monitoring
 Can help to identify suboptimal responders
 Provides opportunities to modify treatment to
enhance antiviral efficacy
 Can help support individualised treatment maps
 Has the potential to improve long-term outcomes
Response markers act as signposts
for clinical management
Additional
interventions
required
Chosen therapy
is effective and
well tolerated

HBV Roadmap Proposal: Monitoring
 Monitor every 3 months
 If patient achieves complete response by 48 weeks, follow
monitoring recommendation (6-monthly)
 If patient shows continuous decline up to 48 weeks, but still has
higher viral load than a complete responder, continue to monitor
every 3 months
 If patient shows an increase or ‘plateauing’ of viral level, they
should be treated based on roadmap recommendation for
inadequate or non-responder
 In patients with more advanced disease, more frequent
monitoring may be indicated
Keeffe et al 2007
35
Summary and Conclusions
Importance of early monitoring of virologic response to therapy
 Early and sustained viral suppression has been
associated with prevention of disease progression
 HBV DNA is a critical signpost in the on-treatment
management of CHB
 On-treatment management offers opportunities to
optimise treatment response
– Essential to identify suboptimal responses
– Modify management to enhance antiviral efficacy
– Potential to improve long-term outcomes

Conclusion from
Report of an International Workshop: Roadmap for Management
of Patients Receiving Oral Therapy for Chronic Hepatitis B
Early monitoring of the virologic response to therapy in chronic
hepatitis B treated with oral nucleos(t)ides is essential…
Use of this roadmap should permit improved individualized ontreatment management designed to enhance long-term patient
outcomes
