Background And Aims: Multiple direct-acting antiviral (DAA) regimens are available to treat HCV genotype 1 infection. However, comparative effectiveness from randomized controlled trials of DAA regimens is unavailable.
Approach And Results: We conducted a pragmatic randomized controlled trial (NCT02786537) to compare the effectiveness of DAAs for HCV genotype 1a or 1b on viral response, safety, tolerability, and medication nonadherence.
Background & Aims: Direct-acting antiviral (DAA) therapy is used in patients with HCV-related decompensated cirrhosis with the expectation of improving hepatic function. However, little is known about the long-term hepatic benefit of successful antiviral treatment.
Methods: Patients with advanced/decompensated cirrhosis (model for end-stage liver disease [MELD] ≥10), in whom NS5A-containing DAA therapy was initiated prior to September 2018, were included (from the HCV-TARGET cohort).
Recent studies have suggested a negative impact of hepatocellular carcinoma (HCC) on sustained virologic response (SVR) to hepatitis C virus (HCV) direct acting antivirals (DAAs). We compared the effectiveness of DAAs in patients with cirrhosis, with and without HCC, and in those with HCC partially treated or untreated (PT/UT-HCC) versus completely treated (CT-HCC). HCC status was based on imaging 6 months before or 2 months after start of DAA therapy.

- Researchers conducted a phase 3b trial to evaluate the safety and efficacy of glecaprevir/pibrentasvir (G/P) for patients with hepatitis C (HCV) who previously failed treatment with sofosbuvir and an NS5A inhibitor.
- The study included 177 patients, showing high sustained virologic response rates ranging from 86% to 97% across different treatment durations and combinations, with a low overall treatment failure rate.
- G/P was generally well tolerated, although adding ribavirin led to more adverse events without improving treatment success.
Background & Aims: We aimed to evaluate the safety and effectiveness of 12 or 24 weeks treatment with ledipasvir and sofosbuvir, with or without ribavirin, in treatment-experienced patients with hepatitis C virus (HCV) genotype 1 infection and cirrhosis in routine clinical practice. Patients were followed in a multi-center, prospective, observational cohort study (HCV-TARGET).
Methods: We collected data from 667 treatment-experienced adults with chronic genotype 1 HCV infection who began treatment with ledipasvir and sofosbuvir, with or without ribavirin, from 2011 through September 15, 2016, according to the regional standards of care, at academic (n = 39) and community (n = 18) centers in the United States, Canada, Germany, and Israel.
Unlabelled: Data outside of clinical trials with direct-acting antiviral regimens with or without ribavirin as treatment of chronic hepatitis C virus in solid organ transplant recipients are limited. Liver transplant (LT), kidney transplant (KT), and dual liver kidney (DLK) transplant recipients from the Hepatitis C Therapeutic Registry and Research Network database, a multicenter, longitudinal clinical care treatment cohort, treated with direct-acting antiviral regimens between January 1, 2014, and February 15, 2016, were included to assess safety and efficacy. Included were 443 posttransplant patients (KT = 60, LT = 347, DLK = 36); 42% had cirrhosis, and 54% had failed prior antiviral therapy.

We analyzed data from a multicenter, prospective, observational study to determine real-world sustained virologic responses 12 weeks after treatment (SVR12) with regimens containing ledipasvir and sofosbuvir and identify factors associated with treatment failure.
Methods: We collected data from 2099 participants in the HCV-TARGET study with complete virologic data (per-protocol population).
Objective: Due to a high efficacy in clinical trials, sofosbuvir (SOF) and ribavirin (RBV) for 12 or 16 weeks is recommended for treatment of patients with HCV genotype (GT) 2 infection. We investigated safety and effectiveness of these regimens for GT2 in HCV-TARGET participants.
Design: HCV-TARGET, an international, prospective observational study evaluates clinical practice data on novel antiviral therapies at 44 academic and 17 community medical centres in North America and Europe.
Background: Sofosbuvir (SOF) is active against all hepatitis C virus (HCV) genotypes, and SOF-based therapies lead to high rates of sustained virologic response (SVR). However, genotype 3 (GT3) HCV remains a challenge with lower SVR rates reported, particularly in patients with cirrhosis. This study reports the effectiveness and safety of SOF-based therapy in patients with GT3 HCV treated in clinical practice.

Methods: In 90 medical centres, patients with chronic HCV received pegylated interferon, ribavirin, and either telaprevir or boceprevir per local standard of care. Demographic, adverse event, clinical, and virological data were collected during treatment and follow-up.
