In this study, we assessed phenotypic susceptibility to dolutegravir and raltegravir in a large variety of HIV-1 ‘non-B’ subtypes (n = 72) issued from integrase inhibitor-naive clinical isolates. All samples were susceptible to both dolutegravir and raltegravir with median IC50 values of 1.22 nmol/l and 1.53 nmol/l, respectively; similar to that observed for the B subtype. Thus, despite the high prevalence of polymorphic substitutions in integrase in ‘non-B’ clinical isolates, phenotypic susceptibility to dolutegravir remained unchanged.
