AbstractIntegrase inhibitor is uniquely available as single tablet regimen (STR) in Korea. In this study, the durability until 96 weeks was compared between dolutegravir/abacavir/lamivudine (D/A/L) and elvitegravir/cobicistat/tenofovir/emtricitabine (E/T/E) in treatment naïve human immunodeficiency virus 1 (HIV-1) infected individuals. From 2014 to 2017, 153 and 234 subjects started D/A/L and E/T/E, respectively. During 96 weeks, 73 discontinued initial STR and the reason of discontinuation was typable in 44. The frequency of drug adverse event related discontinuation (AEDC) was higher in D/A/L (13.1% vs. 6.4%, P = 0.023) while most non-AE related discontinuations occurred in E/T/E (8/9), such as drug-drug interaction, meal requirement and virologic failure. AEDC occurred usually within 24 weeks (20/35) and D/A/L to E/T/E AEDC incidence rate ratio was 3.71 (95% confidence interval, 1.36-10.10) in this period. Regarding the durability, D/A/L and E/T/E revealed no significant difference at week 96 (P = 0.138) while durability of D/A/L was worse in the aspect of AEDC (P = 0.013).© 2020 The Korean Academy of Medical Sciences.
