Effectiveness of ombitasvir/paritaprevir/ritonavir, dasabuvir for HCV in HIV/HCV coinfected subjects: a comprehensive analysis.

BACKGROUND: Data on the treatment of patients with hepatitis C virus (HCV)/human immunodeficiency virus (HIV) coinfection remains limited. A comprehensive analysis was performed to evaluate the efficacy and safety of ombitasvir (OBV)/paritaprevir (PTV)/ritonavir(r) ± dasabuvir (DSV) ± ribavirin (RBV) for treatment in HCV/HIV coinfected patients.

METHODS: We systematically searched and included studies that enrolled patients with HIV/HCV coinfection using the OBV/PTV/r ± DSV ± RBV regimens and reported sustained virological response after 12 weeks (SVR12) end-of-treatment. Heterogeneity of results was assessed and pooled SVR rates were computed with 95% confidence intervals (95%CI). Subgroup analysis and assessment of publication bias through Egger's test were further performed.

RESULTS: Ten studies containing 1358 coinfected patients were included in this study. The pooled estimate of SVR12 was 96.3% (95%CI: 95.1-97.4). Subgroup analysis showed that pooled SVR12 rate was 96.2% (95% CI: 94.8-97.4) for patients with genotype (GT) 1 and 98.8% (95% CI: 95.1-100.0) for those with GT4. The SVR12 rates for the treatment-naïve (TN) and treatment-experienced (TE) patients were 96.8% (95% CI, 94.8-98.5) and 98.9% (95% CI, 96.4-100.0), respectively. Pooled SVR12 rate was 97.8(95%CI: 94.6-99.8) for patients with cirrhosis and 96.7% (95%CI: 95.3-97.8) without cirrhosis. The pooled incidence of any adverse events (AEs) and serious adverse events (SAEs) was 73.9% (95%CI: 38.1-97.6) and 2.7% (95%CI: 0.0-9.5). Publication bias did not exist in this study.

CONCLUSIONS: The comprehensive analysis showed high efficacy for the OBV/PTV/r ± DSV ± RBV regimen in patients coinfected with HIV and HCV, regardless of genotypes, history of treatment and the presence or absence of cirrhosis.
