Clinical Trials for People with Suboptimal Immune Reconstitution Despite HIV Suppression

Last updated 6/9/2017

Some individuals who initiate antiretroviral therapy (ART) experience limited recovery of CD4 T cell numbers despite suppression of HIV viral load to undetectable levels. The most common risk factors for this type of discordant response to ART are low CD4 T cell count at the time of starting and older age. Individuals in this situation still experience a benefit from ART in terms of a greatly reduced risk of opportunistic infections, illness and death, but their risk of these outcomes is higher than among people with greater CD4 T cell gains (for additional background see TAGline, Spring 2013). For this reason, a number of clinical trials are investigating approaches that might boost CD4 T cell recovery in individuals whose CD4 T cell counts remain relatively low despite viral load suppression. The purpose of this page is to provide a resource listing of these clinical trials, which will be updated on an ongoing basis.
