2016/2017 - New HCV two and three drug regimens on their way: what do they promise?

Summary for AASLD 2016 for Hepatitis C - New HCV two and three drug regimens on their way: what do they promise? And what do clinicians need to look out for under DAA combination therapy and beyond SVR?
Jurgen K. Rockstroh M.D., Professor of Medicine University of Bonn, Germany

Jules Levin Executive Director of National AIDS Treatment Advocacy Project (NATAP) recently added this complete summary of AASLD 2016 including links to each study cited in the article. Here is a summary of the topics and introduction with a few links of interest, click here to view the full text article.

Topic Summary
Risk of HBV reactivation after starting DAA therapy
Surveillance for hepatocellular carcinoma (HCC) and risk for HCC after achieving SVR following DAA therapy.
Intravenous drug users and patients on opioid substitution therapy
Patients in the prison setting
HIV/HCV coinfected patients
Patients with renal insufficiency or on hemodialysis
Patients older than 70 years
Patients receiving short treatment durations of 8 week
HCV three drug rescue combinations with licensed drugs
New dual DAA combinations
New three drug combinations


At present, besides the Abbvie 3-D regimen, mostly dual hepatitis C (HCV) direct acting antiviral (DAA) combinations which are coformulated as single tablet regimens have become the gold standard for first line treatment of all HCV genotypes. Despite SVR rates on average above 95% there are still attempts in the field to develop three drug combinations (so called triplets) or very potent new dual regimens which may allow shortening of treatment duration and may also add to the antiviral pangenotypic activity of all oral DAA combination therapy. Obviously, even with the currently licensed HCV drugs, three drug combinations may play a role in retreatment of the few patients which experience virological failure under dual DAA-based HCV therapy. Various studies at AASLD this year where devoted to effectiveness and safety of these new three DAA regimens in treatment naïve as well as treatment experienced patients including prior DAA-based treatment failure (1-7). In addition, data on the new and very potent Abbvie dual combination (Glecaprevir (ABT-493)/Pibrentasvir (ABT-530)), again in treatment-naïve, experienced- and prior DAA-failures, was presented (8-10). Another important topic was feedback on safety and effectiveness of various all oral DAA combinations from real-world cohorts including a whole variety of special populations including intravenous drug users, patients on opioid substitution therapy, patients in the prison setting, HIV coinfected, patients with renal insufficiency, patients older than 70 years, patients receiving short treatment durations of 8 week and much more (11-19). As more and more data arises from very diverse patient populations it appears as if no special or hard to treat patient group seems to exist any longer. In the end it really is more about getting access to therapy feasible for some of those more marginalized patient groups. A further important topic was around clinically relevant issues which clinicians who treat HCV need to be aware of, including risk for hepatitis B (HBV) reactivation after starting DAA therapy, as well as the risk for development of hepatocellular cancer (HCC) after achieving SVR (20-24). Although HCV remained to be a widely recognized topic throughout AASLD, it is becoming apparent that other topics in hepatology including NASH, alcoholic hepatitis, hepatitis B, HCC and primary biliary cholangitis are gaining importance and presentation space especially in the late-breaker session. A more intensified discussion on national HCV screening programs, HCV treatment uptake and linkage to care at AASLD would be desirable to politically underline the need to continue the fight to ensure global access of HCV therapies throughout the world.

AASLD 2016 Review - Watch Advances in Chronic Hepatitis C: Management and Treatment

After each conference this blog links to a series of education-related information on important findings related to ongoing challenges of managing and treating viral hepatitis. Listed below are three programs offering a review of key studies presented at the American Association for the Study of Liver Diseases 67th Annual Meeting 2016.

Internet symposium at ViralEd - Advances in Chronic Hepatitis C: Management and Treatment
The CME Internet Symposium: AASLD 2016 Expert Review will feature four HCV experts reviewing and discussing key presentations on chronic hepatitis C presented at AASLD 2016. The review and discussion will focus on HCV therapeutic options and developments, including: current treatment and management strategies, algorithms and recommendations; therapies in development; epidemiology; and diagnosis and clinical management of specific patient populations, including HCV/HIV co-infected and cirrhotic patients.
