- BACKGROUND: Nonnucleoside reverse transcriptase inhibitors (NNRTIs) are recommended as part of first-line treatment for HIV-1 in Africa. However, NNRTI-based regimens are more prone to resistance development than protease inhibitors (PIs) in a context in which drug interruptions are frequent. The aim of this study was to compare the efficacy and tolerability of NNRTIs with PIs in HIV-1-infected patients in Guinea-Bissau.METHODS: This open-label randomized, 2-arm superiority trial compared the use of 2 NRTIs plus either one NNRTI (efavirenz or nevirapine) or one PI (lopinavir/ritonavir) in treatment-naive HIV-1-infected adults in the Bissau HIV Cohort (ClinicalTrials.gov, NCT0019235). The primary endpoint was HIV-1 RNA <400 copies per milliliter after 12 months of treatment.RESULTS: Between May 5, 2011, and April 26, 2013, 400 patients were included in the study. In an intention-to-treat analysis, the proportions of patients with viral suppression were similar in the NNRTI [65/197 (33.0%)] and PI [68/203 (33.5%)] arms (P = 0.92). No PI resistance was detected, but high-level NNRTI resistance was seen in 17/30 (56.7%) of NNRTI vs. 3/26 (11.5%) of PI-treated patients, P < 0.01. After 1 year of follow-up, 65 patients died (16.3%) and 93 were lost to follow-up (23.3%). There was no difference in mortality (hazard ratio 0.84, 95% confidence interval: 0.51 to 1.36) or frequency of clinical adverse events between treatment arms [NNRTI: 73/197 (37.1%); and PI: 69/203 (34.0%); P = 0.52].CONCLUSIONS: In patients at an HIV clinic in Guinea-Bissau, treatment with PIs led to less development of resistance compared with NNRTIs but was not superior in terms of viral suppression, CD4 cell increment, mortality, or severe adverse events.
