Primary objective* To assess the non-inferiority of darunavir/r + raltegravir compared to darunavir/r + tenofovir/emtricitabine as first-line treatment strategies in HIV-1 infected, antiretroviral naïve adults over at least 96 weeks (i.e. to assess…
Primary: Antiviral efficacy after 48 weeks of treatment. Secundary: Antiviral efficacy after 24 weeks, safety and tolerability, resistance development, PK, incidence of HIV-associated conditions, gender-, race-, and/or HIV-1 subtype on response to…
To determine the effect of chronic use of ginkgo biloba on the single-dose pharma-cokinetics (AUC0-inf, AUC0-12, Cmax, C12) of raltegravir 400mg in healthy volunteers.
Primary: To compare the pharmacokinetics of raltegravir 400 mg twice daily vs. ralte-gravir 800 mg once daily (QD) by intrasubject comparison. Secondary: To determine the efficacy of an antiretroviral regimen consisting of raltegravir 800mg QD,…
Primary objectiveTo determine the effect of steady state boceprevir on the pharmacokinetics (AUC0-12h, Cmax, C12h) of a single dose raltegravir.Secondary objectives:To determine the effect of a single dose raltegravir on the pharmacokinetics (AUC0-…
In vitro data indicate that raltegravir is not a substrate of UGT1A4 or UGT2B7, but there is no evidence that raltegravir itself does not influence metabolism of other agents mediated by either UGT1A4 or UGT2B7.
To assess non-inferiority of a regimen containing ritonavir-boosted elvitegravir versusraltegravir, each administered with a background regimen in HIV-1 infected,antiretroviral treatment-experienced adult subjects as determined by the proportion…
