Remaining Issues

Remaining Issues

• Genotype 3 patients

• Ribavirin vs longer duration

• Drug-drug interactions (HIV patients, 3D regimens)

• Actual results in the real-life setting

• HCV resistance to DAAs in failing patients

• Implementation

27 12/12/2014

Conclusions

• HCV is the only curable chronic viral

• Greater understanding of the HCV lifecycle has provided a new toolbox of highly effective strategies • PEG-IFN-containing • PEG-IFN-free ++++

• Challenges remain in implementation

• Treatment recommendations will continue to evolve as more data becomes available
