Abstract Background The Simeprevir ObservatioNal Effectiveness across practice seTtings (SONET) study evaluated the real-world effectiveness of simeprevir-based treatment for hepatitis C virus (HCV) infection. Methods The SONET study was a phase 4, prospective, observational, United States–based study enrolling patients ≥18 years of age with chronic genotype 1 HCV infection. The primary endpoint was the proportion of patients who achieved sustained virologic response 12 weeks after the end of treatment (SVR12), defined as HCV ribonucleic acid undetectable ≥12 weeks after the end of all HCV treatments. Results Of 315 patients (intent-to-treat [ITT] population), 275 (87.3%) completed the study. Overall, 291 were treated with simeprevir + sofosbuvir, 17 with simeprevir + sofosbuvir + ribavirin, and 7 with simeprevir + peginterferon + ribavirin. The majority of patients were male (63.2%) and white (60.6%); median age was 58 years, 71.7% had genotype/subtype 1a, and 39.4% had cirrhosis. The SVR12 was achieved by 81.2% (255 of 314) of ITT patients (analysis excluded 1 patient who completed the study but was missing SVR12 data); 2 had viral breakthrough and 18 had viral relapse. The SVR12 was achieved by 92.4% (255 of 276) of patients in the modified ITT (mITT) population, which excluded patients who discontinued treatment for nonvirologic reasons before the SVR12 time point or were missing SVR12 assessment data. Among mITT patients, higher SVR12 rates were associated with factors including age ≥65 years, non-Hispanic/Latino ethnicity, and employment status, but not genotype/subtype nor presence of cirrhosis. Simeprevir-based treatment was well tolerated; no serious adverse events were considered related to simeprevir. Conclusions In the real-world setting, simeprevir + sofosbuvir treatment was common and 92% of mITT patients achieved SVR12. Simeprevir-based treatment was effective and well tolerated in this cohort, including patients with cirrhosis.

Background/Aims: Ledipasvir/sofosbuvir (LDV/SOF) shows high efficacy and safety in patients with genotype 1-hepatitis C virus (HCV). We aimed to investigate the efficacy and safety of LDV/SOF in real-world Mongolian patients.Methods: Between 2015 to 2019, 23 (0.5%) and 5,005 patients (99.5%) with genotype 1a and 1b HCV, respectively, were treated with a fixed-dose tablet containing 90 mg ledipasvir and 400 mg sofosbuvir for 12 weeks, and 81 patients (1.6%) with previous experience of interferon (IFN)-based treatment received additional 1,000 mg ribavirin. HCV RNA was measured at 4, 12, and 24 weeks after the first dose to determine rapid virologic response, end of treatment response (ETR), and sustained virologic response at 12 weeks after end of treatment (SVR12).Results: Most patients (n=5,008; 99.6%) achieved ETR and SVR12 without virologic relapse. Patients with genotype 1a showed low rates of ETR and SVR12 in only 16 patients (69.6%). There was no significant difference in SVR12 rate between patients regardless of IFN experience (n=81; 1.6%), cirrhosis (n=1,151; 22.9%), HCV RNA >6×10<sup>6</sup> IU/mL (n=866; 17.2%), or liver stiffness >9.6 kPa (n=1,721; 34.2%) (100.0%, 99.3%, 99.4%, and 99.4%, respectively). No severe adverse events (AEs) were reported, and there was no dose reduction or interruption due to AE. The most common AEs were headache (n=472; 9.4%), fatigue (n=306; 6.2%), abdominal discomfort (n=295; 5.9%), and skin rash (n=141; 2.8%).Conclusions: LDV/SOF showed high efficacy and safety for patients with genotype 1, especially 1b HCV, in Mongolia. The real-world data might be applicable to patients in other Asian-Pacific countries.

Background: In elderly individuals aged ≥65 years with hepatitis C virus (HCV) infection, efficacious and safe HCV therapy is complicated by frequent comorbidities and concomitant medications. The aim of this analysis was to evaluate the efficacy and safety of elbasvir/grazoprevir (EBR/GZR) in people aged ≥65 years. Methods: This is an integrated retrospective analysis of EBR/GZR administered for 12 weeks in participants with HCV genotype 1 or 4 infection enrolled in 12 Phase 2/3 clinical trials. The primary end point was sustained virologic response 12 weeks after completing therapy (SVR12; HCV RNA below the lower limit of quantification). Results: Most participants aged ≥65 years were receiving ≥1 concomitant medication (322/339; 95.0%) and had ≥1 comorbidity (334/339; 99%). SVR12 rates were 95.3% (323/339) in participants aged ≥65 years and 95.4% (2,041/2,139) in those aged <65 years. Rates of adverse events, drug-related adverse events, serious adverse events, and discontinuations were similar in participants aged ≥65 years and those aged <65 years. In participants aged ≥65 years, median estimated glomerular filtration rate was similar at baseline and at the end of treatment. Conclusion: The efficacy and safety of EBR/GZR were similar in participants with HCV infection aged ≥65 years and those aged <65 years.

Background & Aims: Hepatitis C virus (HCV) infection is a common condition with endemic prevalence in some areas of the world. In Romania, the mean prevalence is about 3%. New treatments have become available on the market in recent years and new drugs are in the pipeline. A re-evaluation of HCV therapy was considered mandatory. The Romanian Society of Gastroenterology and Hepatology undertook this task for the practitioners of this country.Methodology: A group of recognized experts was created who screened the available literature and the major available guidelines. A list of items requiring attention was created and these were discussed and rated. Decisions were taken by consensus.Recommendations: We present here the second part of the Society’s recommendations for chronic HCV infection treatment. An agreement between experts was reached regarding the therapy of the special categories of patients infected with HCV, complications and monitoring of the therapy, follow-up of the patients who reached sustained virologic response and re-treatment of the patients with therapy failure.Conclusions: This Position Paper represents a guide for the assessment and the therapy of HCV infection. The recommendations are in concordance with other guidelines but are applied to real-life conditions in Romania. Abbreviations: CKD: Chronic kidney disease; DAAs: Direct-acting antivirals; DDIs: Drug-drug interactions; ESDL: End-stage liver disease; FCH: Fibrosing cholestatic hepatitis; GT: Genotype; HCV: Hepatitis C virus; HCC: Hepatocellular carcinoma; LT: Liver transplantation; MELD score: Mayo-Clinic End-Stage Liver Disease score; PDC: Premature discontinuation; PWID: Persons who inject drugs; RASs: Resistance associated substitutions; RBV: Ribavirin; RCT: Randomized controlled trial; SAE: Serious adverse events; SRGH: Romanian Society of Gastroenterology and Hepatology; SVR: Sustained virologic response.

AbstractClinical trials showed pangenotypic direct-acting antivirals’ (DAAs) excellent efficacy and safety when treating hepatitis C virus (HCV). Two pangenotypic regimens were examined, glecaprevir/pibrentasvir (GLE/PIB) and sofosbuvir/velpatasvir (SOF/VEL), in a real-world Taiwanese setting, including all HCV patients treated with GLE/PIB or SOF/VEL from August 2018 to April 2020. The primary endpoint was sustained virologic response 12 weeks after treatment cessation (SVR12), including adverse events (AEs). A total of 1,356 HCV patients received pangenotypic DAA treatment during the study: 742 and 614 received GLE/PIB and SOF/VEL, respectively. The rates of SVR12 for GLE/PIB and SOF/VEL were 710/718 (98.9%) and 581/584 (99.5%), respectively, by per-protocol analysis, and 710/742 (95.7%) and 581/614 (94.6%), respectively, by evaluable population analysis. Eleven (GLE/PIB: 8, SOF/VEL: 3) did not achieve SVR12. The most common AEs for GLE/PIB and SOF/VEL were pruritus (17.4% vs. 2.9%), abdominal discomfort (5.8% vs. 4.4%), dizziness (4.2% vs. 2%), and malaise (3.1% vs. 2.9%). Laboratory abnormalities were uncommon; only < 1% exhibited elevated total bilirubin or aminotransferase levels with both regimens. Five drug discontinuations occurred due to AEs (bilirubin elevation: 3; dermatological issues: 2). Pangenotypic DAAs GLE/PIB and SOF/VEL are effective and well tolerated, achieving high SVR12 rates for patients with all HCV genotypes.

Currently, hepatitis C virus (HCV) infection is considered a serious health-care problem all over the world. A good number of direct-acting antivirals (DAAs) against HCV infection are in clinical progress including NS3-4A protease inhibitors, RNA-dependent RNA polymerase inhibitors, and NS5A inhibitors as well as host targeted inhibitors. Two NS3-4A protease inhibitors (telaprevir and boceprevir) have been recently approved for the treatment of hepatitis C in combination with standard of care (pegylated interferon plus ribavirin). The new therapy has significantly improved sustained virologic response (SVR); however, the adverse effects associated with this therapy are still the main concern. In addition to the emergence of viral resistance, other targets must be continually developed. One such underdeveloped target is the helicase portion of the HCV NS3 protein. This review article summarizes our current understanding of HCV treatment, particularly with those of NS3 inhibitors.

ABSTRACT Hypericin is a natural derivative of the common St. Johns wort plant, Hypericum perforatum. It has in vitro activity against several viruses, including bovine diarrhea virus, a pestivirus with structural similarities to hepatitis C virus (HCV). We conducted a phase I dose escalation study to determine the safety and antiviral activity of hypericin in patients with chronic HCV infection. The first 12 patients received an 8-week course of 0.05 mg of hypericin per kg of body weight orally once a day; 7 patients received an 8-week course of 0.10 mg/kg orally once a day. At the end of the 8-week period of treatment, no subject had a change of plasma HCV RNA level of more than 1.0 log10. Five of 12 subjects receiving the 0.05-mg/kg/day dosing schedule and 6 of 7 subjects receiving the 0.10-mg/kg/day dosing schedule developed phototoxic reactions. No other serious adverse events associated with hypericin use occurred. The pharmacokinetic data revealed a long elimination half-life (mean values of 36.1 and 33.8 h, respectively, for the doses of 0.05 and 0.1 mg/kg) and mean area under the curve determinations of 1.5 and 3.1 μg/ml × hr, respectively. In sum, hypericin given orally in doses of 0.05 and 0.10 mg/kg/d caused considerable phototoxicity and had no detectable anti-HCV activity in patients with chronic HCV infection.

Background: Although several regimens have been approved for the treatment of hepatitis C virus (HCV) infection, sofosbuvir-based regimens are not approved for the treatment of HCV infection in patients with severe renal impairment. Methods: This study was conducted on 51 hemodialysis patients infected with HCV. The patients received a constant dose of sofosbuvir/daclatasvir (SOF/DCV). Sustained virologic response (SVR) was evaluated 12 weeks after completion of treatment. The subjects were selected and treated with a combination of SOF/DCV. Eleven patients expired during the anti-HCV treatment due to causes not related to liver disease or antiviral therapy. Results: Finally, 40 patients finished the treatment, and 36 cases were evaluated for SVR. Among those tested for SVR, 35 (97.2%, 95% CI: 85.5 - 99.9%) achieved SVR and one (2.8%, 95% CI: 0.1 - 14.5%) relapsed. No patient reported severe adverse events. Conclusions: The combination of SOF/DCV showed great efficacy and safety in hemodialysis patients with severe renal impairment and chronic HCV infection.

Stage Renal Disease

Background: Hepatitis C virus (HCV) infection is common among patients on haemodialysis (HD) therapy and is an important cause of morbidity and mortality. In patients with chronic kidney disease (CKD), the risks for negative outcomes are significantly higher in HCV-infected patients than in those without HCV infection, including progression to cirrhosis, hepatocellular carcinoma and liver-related mortality. Ombitasvir (OBV), paritaprevir (PTV), ritonavir (r), and dasabuvir (DSV) are all hepatically metabolized and, therefore, require no dose adjustment in patients with any degree of renal impairment. Aims: We studied the safety and efficacy of OBV/PTV/r + DSV in a small group of HCV infected patients on haemodialysis therapy. Methods: Treatment course with ombitasvir/paritaprevir/ritonavir and dasabuvir; (3-DAA regimen of OBV/PTV/r+DSV±RBV) was analysed. Pre-treatment evaluation of HCV infection included HCV RNA, genotype, and liver fibrosis assed by transient fibroelastography (FibroScan). The stage 5 CKD was defined as an eGFR of &lt;15 mL/min/1.73 m2, respectively; those on haemodialysis were considered to have stage 5 CKD or end-stage renal disease (ESRD). Demographic data and concomitant medication were retrieved from patients’ records. The primary endpoint was sustained virologic response at post-treatment week 12 (SVR12). We collected data on on-treatment adverse events (AEs), serious AEs, and laboratory abnormalities. Results: Among 7 treated patients, 6 were male and 1 female, all were infected with genotype 1 (5 GT1b, 2 GT1a). Patient had compensated liver cirrhosis and six patients did not have liver cirrhosis, none were liver transplant recipients. All of seven patients completed 12 weeks of treatment and achieved SVR12. Concomitant medication had to be modified with the treatment initiation in 5 out of 7 patients. One of the patients presented with a significant decrease in haemoglobin level, white blood cell and platelet count during the treatment period. The most frequent adverse events were nausea, diarrhoea. Adverse events were primarily mild, and no patient discontinued treatment due to an AE. Conclusions: Treatment with OBV/PTV/r +DSV ± RBV was well-tolerated and resulted in high rates of SVR12 (100%) for patients with HCV GT1b/1a on haemodialysis.
