Study design
The Metabolic Effects of Different Classes of Antiretrovirals Study (MEDICLAS) is a multicentre and multinational two-arm clinical trial based in Helsinki, Amsterdam, den Haag, Haarlem, Leiden, Rotterdam, Barcelona, and London. The principal aim of the trial was to investigate the effect of different combinations of antiretroviral therapy, Lopinavir (400mg/day) or Ritonavir (100mg/day) and Zidovudine (300mg/day) or Lamivudine (150mg/day) versus Lopinavir (533mg/day) or Ritonavir (133mg/day) and Nevirapine (200mg/day) on metabolic and vascular changes in HIV-infected men. Individuals were eligible for inclusion if they were aged between 18 and 70 years with an indication to initiate a combination antiretroviral therapy. The study was approved by the ethics committees of all participating centres. Written informed consent was obtained from all participants before study entry.
