Brief Summary:
The HIV epidemic represents one of the greatest health challenges worldwide, with important social and economic implications for public health. Although combination antiretroviral therapy (TAR) is effective in controlling infection and delaying disease onset, as well as improving the quality of life of infected persons, the relevant medical needs caused by HIV-1 infection are not yet fully met by TAR. The main obstacle to curing HIV is the establishment and maintenance of the viral reservoir. Therefore, we believe that this clinical trial will provide knowledge, for the first time, of the increase of antiretroviral drug levels in lymphatic tissue achieved by simultaneous administration of antiretroviral drugs at higher than usual doses, and their effect on persistent viral replication in intestinal lymphatic tissue and, as a consequence, on the latent cellular reservoir of HIV.
Detailed Description:
Data on the penetration of antiretrovirals into the tissues of long-term treated HIV patients are very limited. Previous pharmacokinetic studies indicate that tissue concentrations of the drug are much lower than those observed in plasma of HIV-infected patients or healthy volunteers. In addition, another study has reported that intracellular levels of antiretrovirals are much lower in lymphoid tissues than in peripheral blood after 6 months of TAR initiation, and these levels correlated inversely with ongoing viral replication.
In the line of research that we are raising, a previous study has reported a decrease in intracellular HIV RNA in lymphoid tissue when dolutegravir was administered at higher than usual doses. This is an important advance and new studies should be implemented with a design that allows to potentiate this strategy and significantly decrease the size of the viral reservoir in tissues.
If the hypothesis of the project, which consists mainly in the reduction or elimination of the HIV reservoir, is demonstrated, there would be very important consequences in the area of functional cure of HIV and/or reduction of chronic persistent inflammation, which could generate changes in conventional treatment schemes with great scalability. In addition, it is possible that by decreasing levels of persistent viral replication, an improvement in levels of immune activation and inflammation may also be observed, which would contribute positively to the overall health of the patient. Oral antiretroviral medication is proposed in order to compound a three-drug antiretroviral regimen. The three antiretroviral drugs have been chosen because they are the only ones that allow administration at higher doses without causing increased toxicity: dolutegravir 50 mg/12 h, maraviroc 300 mg/12 h and lamivudine 300 mg/12 h.
