Changes in Cerebral Function in Treatment Naive HIV-1 Infected Subjects Commencing Either Boosted Atazanavir With Truvada or Boosted Darunavir With Maraviroc and Kivexa (CogUK)

15. oktober 2019 opdateret af: Imperial College London

A Randomised, Prospective Study, Assessing Changes in Cerebral Function in Treatment Naive HIV-1 Infected Subjects Commencing Either Boosted Atazanavir With Truvada or Boosted Darunavir With Maraviroc and Kivexa.

The purpose of this study is to compare two different combination anti-HIV therapies over 48 weeks and to assess if differences in improvement in the function of the brain are observed over this period.

The study will compare anti-HIV therapy combinations which are currently in use.

The patients will not have had any previous treatment for their HIV infection.

Detaljeret beskrivelse

Impairment in neurocognitive(NC) function in HIV-infected subjects in the current anti-retroviraltreatment (cART) era has been associated with poor compliance with cART, reduced quality-of-life and increased mortality. Reported factors associated with the development of NC function impairment in HIV disease and risks associated with progression of such impairment include degree of immune suppression related to HIV infection, other chronic viral infections (such as chronic hepatitis C co-infection), age and central nervous system (CNS) antiretroviral drug exposure.

One modifiable factor which may be associated with the evolution of NC function impairment is the direct effect of cART on the central-nervous-system (CNS). Certain antiretroviral drugs such as zidovudine, lamivudine, abacavir, nevirapine, efavirenz and indinavir are known to achieve optimal exposure in the cerebro-spinal-fluid (CSF) whereas other drugs, such as the majority of the HIV-1 protease inhibitors penetrate less effectively. Studies to date suggest different cART regimens may have differing effects on NC performance. In the EuroSIDA study, the use of nucleoside-reverse-transcriptase inhibitors was found to specifically protect against the development of HIV related brain disease. More recently, in a small prospective study, ALTAIR, different effect on cerebral function was reported in subjects randomised to commence three different cART regimens.

The investigators propose, in a prospective, randomised study to assess the effects of two different antiretroviral regimens on NC function in HIV infected subjects commencing antiretroviral therapy for the first time.

Tidsramme
Cognitive Function, Global Cognitive Score (Z-score)
Tidsramme: 24 weeks, 48 weeks

When commencing antiretroviral therapy (anti-HIV therapy) for the first time, improvements in the function of the brain are frequently observed. For example memory and concentration may improve. However, whether these improvements may differ between different anti-HIV therapies is largely unknown.

The purpose of this study is to compare two different combination anti-HIV therapies over 48 weeks and to assess if differences in improvement in the function of the brain are observed over this period.

Score increase means improved performance of cognitive function
