Efficacy and safety of etravirine (TMC125) in patients with highly resistant HIV-1: primary 24-week analysis.

Objective: TMC125-C223 is an open-label, partially blinded, randomized clinical trial to evaluate the efficacy and safety of two dosages of etravirine (TMC125), a non-nucleoside reverse transcriptase inhibitor (NNRTI) with activity against wild-type and NNRTI-resistant HIV-1.

Design: A total of 199 patients were randomly assigned 2: 2: 1 to twice-daily etravirine 400 mg, 800 mg and control groups, respectively. The primary endpoint was a change in viral load from baseline at week 24 in the intention-to-treat population.

Once-daily versus twice-daily lamivudine, in combination with zidovudine and efavirenz, for the treatment of antiretroviral-naive adults with HIV infection: a randomized equivalence trial.

A randomized, double-blind, double-dummy controlled, multicenter trial was conducted that involved 554 antiretroviral-naive human immunodeficiency virus-infected adults (plasma HIV type 1 [HIV-1] RNA level, >or=400 copies/mL; CD4(+) cell count, >100 cells/mm(3)) and compared a 300-mg once-daily (q.d.) regimen of lamivudine (3TC) versus a 150-mg twice-daily (b.
