Acceptable ARV : FTC/TDF + EFV or RAL or RPV
LDV/SOF 90mg/400 mg : 1 pill qd

Objective

  • Primary endpoint : SVR12 (HCV RNA < 12 IU/ml) by intention to treat, with 2-sided 95% CI

Baseline characteristics and outcome

Adverse events , n (%)

  • Serious adverse events : 1 (pneumonia)
  • No discontinuation due to adverse event
  • Common adverse events, mostly grade 1 :
    • Nasal congestion 16%)
    • Myalgia (14%)
    • Headache (10%)
    • Fatigue (10%)
    • Diarrhea (8%)
    • Nausea (6 %)
    • Constipation (6%)
    • Urinary tract infection (6%)
  • Grade 4 events : 4 (pneumonia, decrease neutrophil count, elevated AST, CK elevation)
  • No significant changes in serum creatinine or eGFR

Summary

  • In this open- label, uncontrolled, non randomised study, LDV/SOF single tablet regimen was associated with high rates of SVR in patients with HCV genotype 1 and HIV co-infection, similar to that observed inpatients monoinfected with HCV genotype 1
  • Most adverse events were mild (grade 1-2) and clinically manageable
  • Limitations
    • Low sample size
    • Exclusion of cirrhosis
    • Restriction in antiretroviral regimen (exclusion of PI and NNRTI)
    • Exclusion of patients with low CD4 cell counts
