7. Any prior evidence of primary viral resistance based on the presence of any major resistance-associated mutation to backbone NRTI
8. History of prior virological failure,eg 2 consecutive HIV-1 RNA >50 c/ml -at or after week 32 following first ART initiation or confirmed rebound viraemia >200 copies/ml after having a VL of <50 copies/ml without resistance test or with significant mutations to any other ARV regimen (NOTE: Switch for toxicity or tolerability with wild type virus does not count as virological failure)
9. Dialysis or renal insufficiency (creatinine clearance < 50ml/min)
10. History of decompensated liver disease (AST or ALT≥5x the upper limit of normal (ULN) or ALT ≥ )3 x ULN and bilirubin ≥ 1.5 x ULN with > 35% direct bilirubin.
11. Unstable liver disease (as defined by the presence of ascities, encephalopathy, coagulopathy, hypoalbuminemia, esophagael or gastic varices, or persistent jaundice), know biliary abnormalities (with the exception of Gilbert’s syndrome or asymptomatic gallstones))
12. Subjects with severe hepatic impairment (Class C) as determined by Child-Pugh classification (see appendix 5)
13. If female, currently pregnant or breastfeeding
14. Opportunistic infection within 4 weeks prior to first dose of DTG
15. Clinical decision that a switch of antiretroviral therapy should be immediate
16. Screening blood result with any grade 3/4 toxicity according to Division of AIDS (DAIDS) grading scale, except: asymptomatic grade 3 glucose, amylase or lipid elevation or asymptomatic grade 4 triglyceride elevation (re-test allowed).
17. Any condition (including illicit drug use or alcohol abuse) or laboratory results which, in the investigator’s opinion, interfere with assessments or completion of the trial.
18. History or presence of allergy to the study drug or their components |
