title: The danish protease inhibitor study: a randomized study comparing the virological efficacy of 3 protease inhibitor-containing regimens for the treatment of human immunodeficiency virus type 1 infection.
abstract: The Danish Protease Inhibitor (PI) Study has enrolled 318 human immunodeficiency virus (HIV)-infected, PI-naive patients for the purpose of comparing 3 PI-containing regimens for the treatment of HIV infection. The regimens include 2 nucleoside analogues in combination with indinavir (Idr), ritonavir (Rtv), or Rtv and saquinavir (Rtv/Sqv). Similar percentages of patients in the 3 study arms achieved reduced levels (</=20 copies/mL) of HIV RNA. In the area under the curve minus baseline analyses, a better response was found in the Rtv/Sqv arm than in the Rtv arm. No difference was found when comparing Rtv/Sqv with Idr and Rtv with Idr. Patients in the 3 arms had comparable increases in CD4 cell counts. At 72 weeks of follow-up, there was no statistical difference between arms for the primary study end point (</=20 HIV RNA copies/mL); however, some of the additional analyses indicated an advantage for the Rtv/Sqv arm, especially when compared with the Rtv arm.
