Comment

This is a very exciting time for HCV coinfection.

While both telaprevir and boceprevir plus pegIFN and ribavirin continue to be standard of care and dramatically improve response rates in genotype 1 infection, treatment involves complex daily regimens, careful management of interactions with ARVs and other medications and side effects are difficult.

Although ribavirin is likely to continue to be needed with other oral HCV drugs that are furthest in the pipeline, treatment may be able to be shortened to 12 weeks with some combinations. These are generally once-daily drugs with fewer side effects, in all-oral combinations with very high rates of viral efficacy.

While results look impressive and encouraging these were generally interim analyses at early time points, and that patients with decompensated cirrhosis were not included.

Close monitoring is needed to determine the risks of deferring treatment for patients with the lowest risk for liver decompensation.
