A subgroup analysis of black patients with HIV enrolled in the 48-week, open-label SPIRIT (Switching PI to Rilpivirine In-combination with Truvada) trial showed that switching from an antiretroviral regimen consisting of a boosted PI and ritonavir (RTV) plus 2 nucleoside/nucleotide reverse-transcriptase inhibitors (PI+RTV+2NRTIs) to a simplified once-daily, single-tablet regimen of rilpivirine/emtricitabine/tenofovir DF (RPV/FTC/TDF) is safe and effective in this population. [157, 158]

Patients were randomized to undergo an immediate switch to RPV/FTC/TDF at baseline or to maintain their PI+RTV+2NRTIs regimen for 24 weeks and then switch to RPV/FTC/TDF for 24 weeks (delayed switch).

At 24 weeks, a subgroup analysis of black patients in the study showed that viral suppression rates (HIV-1 RNA < 50 copies/mL) were 95% in the RPV/FTC/TDF group and 91% in the group receiving PI+RTV+2NRTIs; ie, no significant difference existed. At 48 weeks, 89% of black patients in the immediate-switch group maintained viral suppression, compared with 95% of those in the delayed-switch group, which again was not considered a significant difference. [157, 158]

At 48 weeks, when all patients in the study were taken into account, there was no significant difference in viral suppression between the immediate-switch (89%) and delayed-switch (92%) groups; the rates of adverse events were similar in both groups as well. [157, 158] However, investigators noted significant improvement in lipid levels in patients who received the single-tablet RPV/FTC/TDF regimen. [158]
