RESUMO
OBJECTIVE: Our objective was to evaluate the prevalence of pre-existing neurological and/or psychiatric comorbidities (NPCs) and efficacy/safety outcomes for participants with versus without baseline NPCs in AMBER and EMERALD. METHODS: AMBER (treatment-naïve population) and EMERALD (virologically suppressed population) were phase III randomized studies of darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) 800/150/200/10 mg. The primary objective of this post hoc analysis was to assess virological response (HIV-1 RNA <50 copies/mL) at week 48 by intent-to-treat US Food and Drug Administration snapshot analysis comparing participants with and without baseline NPCs. RESULTS: Among participants in AMBER, 88/362 (24%) in the D/C/F/TAF arm and 99/363 (27%) in the control arm had baseline NPCs; in EMERALD, 294/763 (39%; D/C/F/TAF) and 166/378 (44%; control) participants had baseline NPCs. At baseline, psychiatric NPCs were more common than neurological NPCs in both studies; the most common of each type were depression and headache, respectively. High virological response rates were achieved with D/C/F/TAF across studies regardless of baseline NPCs at weeks 48 (range 86%-95%) and 96 (range 80%-91%). No participants in either study with a baseline NPC prematurely discontinued because of a study drug-related neurological or psychiatric adverse event. CONCLUSION: D/C/F/TAF may be a suitable treatment option for individuals with HIV-1 and NPCs.
