HIV Research and Treatment

Doravirine is a novel HIV-1 NNRTI recently shown to be non-inferior to both darunavir/ritonavir and efavirenz in combination therapy with two NRTIs in treatment-naive patients. Doravirine has an in vitro resistance profile that is distinct from other NNRTIs and retains activity against viruses containing the most frequently transmitted NNRTI mutations.The aim of this study was to examine the prevalence of doravirine resistance-associated mutations in HIV-1-infected treatment-naive patients in Europe.From 2010 to 2016, 9764 treatment-naive patients were tested for NNRTI antiretroviral drug resistance by bulk sequencing in Greece, Italy and France. We studied the prevalence of doravirine resistance-associated mutations previously identified in vitro: V106A/M, V108I, Y188L, V190S, H221Y, F227C/L/V, M230I/L, L234I, P236L, Y318F and K103N/Y181C.Among 9764 sequences, 53.0% and 47.0% of patients had B and non-B subtypes, respectively. Overall, the presence of at least one doravirine resistance-associated mutation (n = 137; 1.4%) or the K103N/Y181C mutations (n = 5; 0.05%) was very rare. The most prevalent mutations were V108I (n = 62; 0.6%), Y188L (n = 18; 0.2%), H221Y (n = 18; 0.2%) and Y318F (n = 23; 0.2%). The frequency of doravirine resistance-associated mutations was similar between B and non-B subtypes. In comparison, the prevalence of rilpivirine, etravirine, nevirapine and efavirenz resistance was higher whatever algorithm was used (ANRS: 8.5%, 8.1%, 8.3% and 3.9%, respectively; Stanford: 9.9%, 10.0%, 7.5% and 9.4%, respectively).The prevalence of doravirine resistance-associated mutations is very low in antiretroviral-naive patients. These results are very reassuring for doravirine use in naive patients.
