from Jules: This is a small study where patients received efavirenz or Reyataz/r or no AT along with triple HCV therapy including telaprevir, an HCV protease inhibitor. Hit the link above and you can see the telaprevir drug-drug interaction studies with ARTs and you'll see the interactions are too great with the other ARTs except for efavirenz and Reyataz/r so patients at this time can only take Reyataz/r or efavirenz along with telaprevir & peg/rbv. Soon a interaction study with raltegravir will be conducted but an interaction is not expected.
