Abstract
BACKGROUND AND AIMS No direct-acting antiviral is currently approved for acute HCV infection, delaying treatment. We investigated the effectiveness and safety of 8-week glecaprevir/pibrentasvir (G/P) in patients with acute HCV infection. APPROACH AND RESULTS This noninterventional, single-arm, retrospective chart review was designed to enroll adults/adolescents with acute HCV infection. Analyses were conducted on a full analysis set (FAS; all enrolled) and modified FAS (FAS excluding nonvirologic failures). The primary end point (modified FAS) was sustained virologic response at posttreatment week 12 (SVR12) with superiority to 92.6% threshold determined by historic chronic HCV G/P SVR12 rates. Secondary end points (FAS) included SVR12, on-treatment virologic failure, posttreatment relapse, and reinfection. Adverse events and safety laboratory values were assessed.Overall, 202 adults were enrolled; in the modified FAS, 150/151 (99.3%; 95% CI: 96.3-99.9) achieved SVR12, demonstrating superiority to efficacy threshold. In the FAS, the SVR12 rate was 74.3% and the on-treatment virologic failure rate was 0%. Relapse and reinfection rates after the final treatment visit (FAS) were 0.5% and 3%, respectively; 39 patients had missing SVR12 data. No on-treatment alanine aminotransferase elevations > 3 × upper limit of normal with total bilirubin > 2 × upper limit of normal were reported. All 53 patients with alanine aminotransferase Grade ≥ 2 at baseline improved to Grade 0/1 on treatment. No adverse eventss of hepatic decompensation/failure or leading to G/P discontinuation occurred. Two patients had serious adverse events unrelated to G/P. CONCLUSIONS Eight-week G/P therapy was effective and well-tolerated in patients with acute HCV infection. Data support further investigation of G/P in acute HCV to shorten care cascades, reduce transmission, and support HCV elimination.

SASLT guidelines: Update in treatment of hepatitis C virus infection, 2024. Saudi J Gastroenterol 2024; 30:S1-S42.

Abstract
ABSTRACT Hepatitis C virus (HCV) infection has been a major global health concern, with a significant impact on public health. In recent years, there have been remarkable advancements in our understanding of HCV and the development of novel therapeutic agents. The Saudi Society for the Study of Liver Disease and Transplantation formed a working group to develop HCV practice guidelines in Saudi Arabia. The methodology used to create these guidelines involved a comprehensive review of available evidence, local data, and major international practice guidelines regarding HCV management. This updated guideline encompasses critical aspects of HCV care, including screening and diagnosis, assessing the severity of liver disease, and treatment strategies. The aim of this updated guideline is to assist healthcare providers in the management of HCV in Saudi Arabia. It summarizes the latest local studies on HCV epidemiology, significant changes in virus prevalence, and the importance of universal screening, particularly among high-risk populations. Moreover, it discusses the promising potential for HCV elimination as a public health threat by 2030, driven by effective treatment and comprehensive prevention strategies. This guideline also highlights evolving recommendations for advancing disease management, including the treatment of HCV patients with decompensated cirrhosis, treatment of those who have previously failed treatment with the newer medications, management in the context of liver transplantation and hepatocellular carcinoma, and treatment for special populations.

Glecaprevir-pibrentasvir for 4 weeks among people with recent HCV infection: The TARGET3D study. JHEP Rep 2023; 5:100867. [PMID: 37771545 PMCID: PMC10522905 DOI: 10.1016/j.jhepr.2023.100867] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Accepted: 07/01/2023] [Indexed: 09/30/2023] Open
Abstract
Background & Aims Short duration treatment may aid HCV elimination among key populations. This study evaluated the efficacy of glecaprevir-pibrentasvir for 4 weeks among people with recent HCV infection. Methods In this single-arm multicentre international trial, adults with recent HCV (duration of infection <12 months) received glecaprevir-pibrentasvir 300 mg-120 mg daily for 4 weeks. Primary infection was defined as a first positive anti-HCV antibody and/or HCV RNA measurement within 6 months of enrolment and either acute clinical hepatitis within 12 months (symptomatic illness or alanine aminotransferase >10x the upper limit of normal) or antibody seroconversion within 18 months. Reinfection was defined as new positive HCV RNA within 6 months and prior clearance (spontaneous or treatment). The primary endpoint was sustained virological response at 12 weeks post-treatment (SVR12) in the intention-to-treat (ITT) and per-protocol (PP) populations. Results Twenty-three participants (96% men, 70% HIV, 57% ever injected drugs) received treatment, of whom 74% had genotype 1a infection and 35% recent reinfection. At baseline, median duration of infection was 17 weeks (IQR 11-29) and HCV RNA was 5.8 log10IU/ml (IQR 5.2-6.9). SVR12 was achieved by 78% (18/23; 95% CI 56-93%) and 82% (18/22; 95% CI 60-95%) of the ITT and PP populations, respectively, and in 100% (12/12; 95% CI 74-100%) of participants with baseline HCV RNA ≤6 log10. There were four cases of virological failure (relapse); three received retreatment with 12 weeks sofosbuvir-velpatasvir or grazoprevir-elbasvir (SVR, n = 2; loss to follow-up, n = 1). No serious adverse events were reported. Conclusion While most achieved SVR, the efficacy of a 4-week regimen of glecaprevir-pibrentasvir was lower than observed with longer treatment durations (≥6 weeks) among people with recent HCV. Trial Registration Clinicaltrials.gov Identifier: NCT02634008. Impact and implications Short duration treatment may aid HCV elimination among key populations. This investigator-initiated single-arm multicentre international pilot trial demonstrated that efficacy of glecaprevir-pibrentasvir for 4 weeks among people with recent HCV infection was sub-optimal (SVR12 78% ITT, 82% PP). Baseline HCV RNA appeared to impact response, with higher efficacy among participants with lower baseline HCV RNA (≤6 log10; SVR12 100% ITT, 12/12). While most achieved SVR, the efficacy of 4 weeks of glecaprevir-pibrentasvir was below that seen with longer treatment durations (≥6 weeks).
