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

ABSTRACT:

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.

Project description:The combination of ombitasvir (an NS5A inhibitor), paritaprevir (an NS3/4A inhibitor) coadministered with ritonavir (r), and dasabuvir (an NS5B nonnucleoside polymerase inhibitor), referred to as the 3D regimen, and the combination of ombitasvir-paritaprevir-r, referred to as the 2D regimen, have demonstrated high efficacy with and without ribavirin in hepatitis C virus (HCV)-infected subjects. These regimens have potential for coadministration with sofosbuvir (nucleoside NS5B inhibitor) in the treatment of HCV. This phase 1, drug-drug interaction, open-label, multiple-dose study enrolled 32 healthy subjects to receive the 3D or 2D regimen in combination with sofosbuvir. Doses of study drugs were as follows: ombitasvir-paritaprevir-r, 25/150/100 mg daily (QD); dasabuvir, 250 mg twice daily (BID); and sofosbuvir, 400 mg QD. Blood samples were collected on study days 7, 14, and 21 for evaluating drug interaction at steady state. The effect of the 3D and 2D regimens on the pharmacokinetics of sofosbuvir and its circulating metabolite GS-331007 and vice versa was assessed by a repeated-measures analysis. Exposures of the 3D and 2D regimens were similar (?20% change) during coadministration with sofosbuvir and during administration alone. Sofosbuvir exposures were 61% to 112% higher with the 3D regimen and 64% to 93% higher with the 2D regimen than with sofosbuvir alone. GS-331007 total exposures were 27% and 32% higher with the 3D and 2D regimens, respectively, than with sofosbuvir alone. Increases in sofosbuvir and GS-331007 exposures likely resulted from breast cancer resistance protein (BCRP) and/or P glycoprotein (P-gp) transporter inhibition by paritaprevir and ritonavir. No subjects discontinued the study due to study drug-related adverse events. No dose adjustment is recommended for 3D, 2D, or sofosbuvir in clinical trials exploring the safety and efficacy of the combination. (This study has been registered at ClinicalTrials.gov under registration no. NCT02356562 and NCT02292719.).

Project description:Acid-reducing agents (ARAs) and proton-pump inhibitors (PPIs) that increase gastric pH can alter the bioavailability of antiviral drugs, particularly relevant in patients with advanced liver disease caused by chronic hepatitis C virus (HCV) infection seeking therapy. Using integrated data from six phase 3 studies, we report the safety and efficacy of the 3-direct-acting antiviral (DAA) regimen containing ombitasvir (OBV, an NS5A inhibitor), ritonavir-boosted paritaprevir (PTV/r, an NS3/4A protease inhibitor), and dasabuvir (DSV, an NS5B polymerase inhibitor) with or without ribavirin (RBV) for HCV genotype 1 patients taking concomitant ARAs and PPIs.Treatment-naïve or peginterferon/RBV treatment-experienced patients with or without compensated cirrhosis received OBV/PTV/r and DSV with or without weight-based RBV. Rates of sustained virologic response (SVR), defined as HCV RNA below the lower limit of quantification, 12 weeks post-treatment (SVR12) and safety were evaluated in patients who were receiving concomitant ARAs.Among 2,053 patients enrolled and dosed with study drug, 410 (20%) were receiving concomitant ARAs; of these, 308 (15%) were taking concomitant PPIs. Rates of SVR12 were 95.9% (95% confidence interval (CI) 93.5-97.4%) among patients receiving an ARA, and 96.3% (95% CI 95.3-97.2%) in patients not receiving a concomitant ARA. Similarly, among patients receiving a PPI or not, SVR12 was achieved in 95.1% (95% CI 92.1-97.0%) and 96.4% (95% CI 95.5-97.2%), respectively. Response rates were high regardless of treatment regimen (with or without RBV), and among patients receiving a standard or high dose of PPIs. Regarding safety, adverse events and serious adverse events were more frequently reported in patients taking concomitant ARAs, though baseline population differences may have played a role.In phase 3 trials of OBV/PTV/r plus DSV and RBV in HCV genotype 1-infected patients, SVR12 rates were high regardless of ARA/PPI use or PPI dose. These data support the co-administration of this regimen with ARAs including PPIs.
