Abstract
A novel HIV-1 integrase mutation pattern, L74F V75I, which conferred resistance to first-generation integrase strand transfer inhibitors (INSTIs), was identified in a clinical case with virological failure under a raltegravir-based regimen. Addition of L74F V75I to N155H or G140S Q148H increased resistance levels to the second-generation INSTIs dolutegravir (>385- and 100-fold, respectively) and cabotegravir (153- and 197-fold, respectively). These findings are important for the development of an accurate system for interpretation of INSTI resistance and the rational design of next-generation INSTIs.Entities:
