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


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
