  • Final results from two research studies presented at IAS 2015 yesterday demonstrated clear scientific evidence on the benefits of early initiation of antiretroviral therapy (ART). Building on early results of HPTN 052 released in May 2011 that then showed a 96 percent reduction in HIV transmission, the study results presented yesterday provide conclusive evidence that ART should be provided to all HIV-positive people as soon as they are diagnosed for the benefit of both themselves and their sexual partners.

    Jens Lundgren of the University of Copenhagen presented the initial results of the Strategic Timing of AntiRetroviral Treatment (START) study, a randomized trial looking at whether starting ART in people with CD4+ cell counts above 500 cells/mm3, rather than waiting for CD4+ cell counts to drop below 350 cells/mm3, reduces the occurrence of serious morbidity and mortality. START was recently unblinded by the international Data & Safety Monitoring Board (DSMB) 18 months early due to data that showed very clear benefits of immediate treatment versus delayed treatment. Previous studies and guidance from the World Health Organization (WHO) suggested that ART should not be given to patients unless they had symptomatic HIV and/or CD4+ counts that were below 350 cells/mm3. The interim results from START show that ART is safe and effective for all HIV-infected persons regardless of CD4+ count.
