Background: Neuropsychiatric adverse events (AEs) are a common problem with efavirenz treatment.
 
Methods: In the double-blinded, placebo controlled SENSE trial, 157 treatment-naïve patients with HIV RNA >5000 copies/mL were randomised to ETR 400mg once daily (n=79) or EFV 600mg once daily (n=78), plus two investigator-selected NRTIs (TDF/FTC, ABC/3TC or ZDV/3TC). The primary endpoint was the percentage of patients with Grade 1-4 drug-related treatment-emergent neuropsychiatric AEs at Week 12.
 
Results: The patients were 81% male and 85% Caucasian, with median age 36 years, baseline CD4 count 302 cells/uL and HIV RNA 4.8 log10 copies/mL, well balanced between the arms.
 
In the Intent to Treat analysis, Grade 1-4 drug-related neuropsychiatric (NPS) AEs were reported in 13/79 patients (16.5%) in the ETR arm versus 36/78 (46.2%) in the EFV arm (p< 0.001).
 
Grade 2-4 drug-related NPS AE's were reported in 4/79 (5.1%) in the ETR arm versus 13/78 (16.7%) in the EFV arm (p=0.019). Consistent results were seen for the Per Protocol analysis.
 
Using the HIV-Patient Symptoms Profile questionnaire, patients in the ETR arm also reported better neuropsychiatric tolerability than patients in the EFV arm.
 
The reduction in HIV RNA to Week 12 was -2.9 log10 in both treatment arms. The median rise in CD4 count was +146 cells/uL in the ETR arm and +121 cells/uL in the EFV arm. Eighteen patients discontinued the trial by Week 12 (10 in ETR arm, 8 in EFV arm). There were fewer Grade 2-4 elevations in total cholesterol and LDL cholesterol in the ETR arm (3 and 6 patients) versus the EFV arm (18 and 13 patients).
 
Conclusions: After 12 weeks, first-line treatment with ETR 400mg once daily +2NRTIs led to significantly fewer neuropsychiatric adverse events and an improved lipid profile, compared with EFV+2NRTIs. The virologic and immunologic efficacy profiles were similar in the two arms.
