The regimen of raltegravir (RAL), ritonavir-boosted darunavir (DAR/r), and etravirine (ETR) for HIV treatment-experienced patients in a non-clinical trial setting in the rural/semi-urban United States had not been evaluated.
A retrospective cohort analysis was performed of adult patients prescribed the regimen from 2008 to 2013 at a HIV clinic serving such a population.
In all, 51 patients met inclusion criteria including 15 with suppressed viral loads at regimen initiation. Of the 36 patients with detectable viral loads, 22 (61.1%) achieved a plasma HIV-1 RNA level < 50 copies/ml at 28 weeks and 17 maintained viral suppression at 56 weeks (50% of those surviving without death). Of 42 patients with long-term follow-up, mean of 216 ± 83 weeks following regimen initiation, 31 (73.8%) had viral suppression. Suppression was significantly more likely in those patients that maintained adherence.
In a non-urban clinic population from the United States with considerable treatment experience, the combination of RAL, DAR/r, and ETR was well tolerated and resulted in viral suppression in those that maintained adherence. Future prospective studies may better define the role of such a regimen in the context of revised recommendations for first-line medications in the HIV treatment naïve.
