Resistance in Hepatitis C
Source: Clinical Implications of HCV Resistance: Laying the Foundation for Optimal Treatment Today and in the Future

Module

Join Stephane Chevaliez, PharmD, PhD; Paul J. Pockros, MD; and Stefan Zeuzem, MD, as they review and discuss key principles of HCV resistance with currently approved direct-acting antiviral agents, the latest resistance data on agents in development, and important considerations for potential future anti-HCV regimens. These expert faculty members also provide practical strategies for clinical challenges with the newly approved direct-acting agents through a case-based analysis.

Learning Objectives

Upon completion of this activity, participants should be able to:

  • Apply strategies to reduce the development/expansion of resistance to direct-acting antiviral agents when managing patients receiving treatment with approved direct-acting antiviral agents in combination with peginterferon/ribavirin
  • Integrate key principles regarding antiviral resistance when evaluating data on the direct-acting antiviral agents currently in development
  • Evaluate potential future strategies for HCV treatment based on resistance considerations, including the barrier to resistance and patterns of cross-resistance among classes of direct-acting antiviral agents

Topics covered include:

  • Introduction to Drug Resistance in Hepatitis C Virus
  • Key Resistance Principles for Currently Approved Direct-Acting Antiviral Agents
  • Considerations for Retreatment of Previous Peginterferon/Ribavirin Null Responders and Potential Consequences of Protease Inhibitor Resistance
  • Genotype and Resistance Testing
  • Case 1: Previous Null Responder
  • Case 2: Stopping Rules
  • Case 3: Boceprevir Resistance–Associated Variant
  • Future Regimens
  • Future Protease Inhibitors
  • Nucleos(t)ide Polymerase Inhibitors
  • Nonnucleos(t)ide Polymerase Inhibitors
  • NS5A Inhibitors
  • Cyclophilin Inhibitors
  • Summary: Important Considerations to Avoid Resistance-Associated Variants
  • Appendix: Principles of HCV Resistance

  • My Take on the Guidance From AASLD/IDSA for Managing Treatment-Experienced Patients With Genotype 3 HCV Infection and Cirrhosis

    Ira M. Jacobson MD - 11/5/2014    7 comments / Last Comment: 1/25/2015
    When treatment-experienced patients with genotype 3 HCV infection and evidence of advanced liver disease seek care, it’s important to treat them now, even if evidence defining the best regimen is limited.
  • Using Ledipasvir/Sofosbuvir in Cirrhotic, Treatment-Experienced GT1 Patients: 12 Weeks With Ribavirin or 24 Weeks Without?

    Ira M. Jacobson MD - 3/23/2015    
    Although new data suggest comparable efficacy of ledipasvir/sofosbuvir with ribavirin for 12 weeks vs 24 weeks without ribavirin in genotype 1 cirrhotic, treatment-experienced patients, I am not convinced that shortening treatment is the best approach.

    In the current era of HCV therapy, my evaluation of patients now includes more comprehensive screening for extrahepatic disease manifestations and cofactors.

    Coverage of treatment was recently denied for my 23-year-old patient interested in starting therapy to prevent mother-to-child HCV transmission.

    My take on how to manage genotype 3 HCV and how evolving therapeutic options will likely improve outcomes for treatment-experienced cirrhotic patients with genotype 3 HCV infection.
