A Randomized, Placebo-Controlled Trial of Abacavir Intensification in HIV-1–Infected Adults With Virologic Suppression on a Protease Inhibitor–Containing Regimen

HIV Clinical Trials, 01/17/2011

Hammer SM et al. – The strategy of intensification with abacavir in patients who are virologically suppressed on a stable antiretroviral regimen does not confer a clinical or virologic benefit. As antiretroviral regimens have become more potent since this trial was completed, it will be even more difficult to prove that late intensification of already virologically suppressed patients will add benefit. However, studies are warranted with drugs with new mechanisms of action to determine whether the level of persistent viremia below 50 copies/ mL can be further reduced and what influence this may have on latent HIV reservoirs.
