3 Integrase Inhibitors.....
 
 
  Raltegravir has been approved and on the market for a number of years and in now development in the phase 3 stage are 2 additional integrase inhibitors Gilead's elvitegravir and ViiV's dolutegravir both of which will be coformulated in a once daily one-pill per day. Dolutegravir will be coformulated with abacavir. Elvitegravir will be coformulated with tenofovir and boosted with the new Gilead booster cobicistat while dolutegravir is not boosted, and of course raltegravir is also unboosted. Below are the most recent studies reported for these 3 integrase inhibitors and as mentioned above raltegravir has been in the pharmacy for a number of years so the studies below include 4-5 years of raltegravir safety and antiviral activity. Dolutegravir has shown good activity in a number of patients with raltegravir resistance with more advanced data expected soon. Raltegravir is taken twice daily and is not coformulated. How will integrase inhibitors fit into the context of therapy decision making strategies for firstline initial therapy for treatment-naives and for subsequent treatment for 2nd and 3rd line therapy?
