Abstract
Background GRAND PLAN is a prospective, open-label, phase 4 study. Based at a single center and with a single arm, GRAND PLAN evaluated the safety and efficacy of an 8-week course of glecaprevir/pibrentasvir (G/P) among active drug users with hepatitis C virus (HCV) infection in a population enriched for factors that may reduce treatment uptake and success, such as disengagement from health care and unstable housing. Methods Participants were ≥19 years old and actively using drugs and were confirmed viremic, noncirrhotic, and HCV treatment naive. All participants provided informed consent before any study procedures. They received G/P for 8 weeks within a multidisciplinary model of care, with daily, weekly, or monthly dispensing of medications to optimize adherence. Results We identified 117 eligible patients with a median age of 46 years (range, 22-75): 27% were female, 21.4% were Indigenous, 48.7% were unstably housed, and 95.7% were active drug users (94.9% fentanyl). One patient did not start treatment, and 4 underwent <1 week of treatment, leaving 112 completed treatments with 94.6% picking up medications weekly. HCV RNA was undetectable at the end of treatment in all 112 patients. One died of unknown causes shortly after treatment. A cure was demonstrated in 108 of 111 (97.3%) cases at the SVR12 time point (sustained virologic response at ≥12 weeks); the other 3 experienced virologic relapse. Considering the entire cohort, the intent-to-treat success rate was 92.3% (108/117). HCV reinfection was documented at SVR24 in 5 cases, 2 of which were successfully retreated. Conclusions GRAND PLAN demonstrates that administration of an 8-week course of G/P to inner-city residents with HCV infection leads to a cure >95%. With a short course of treatment, G/P is an attractive option for this population in helping us achieve the World Health Organization's HCV objectives by 2030.

Hepatitis C virus reinfection in people living with human immunodeficiency virus in Taiwan after achieving sustained virologic response with antiviral treatment: the RECUR study. Open Forum Infect Dis 2022; 9:ofac348. [PMID: 35928504 PMCID: PMC9345411 DOI: 10.1093/ofid/ofac348] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Accepted: 07/21/2022] [Indexed: 11/13/2022] Open
Abstract
Abstract
Background
Data on hepatitis C virus (HCV) reinfection in East Asian people living with human immunodeficiency virus (HIV) after treatment-induced sustained virologic response (SVR) are limited.
Methods
HIV/HCV-coinfected patients in Taiwan who achieved SVR12 with interferon (IFN) or direct-acting antivirals (DAAs) between 2005 and 2021 underwent HCV RNA measurements at SVR24 and then biannually. HCV reinfection was defined as the detection of different HCV strains beyond SVR12. HIV-negative, low-risk individuals with SVR12 served as reference patients. Crude reinfection rates and secular trends were assessed. Multivariate Cox regression analysis was performed to identify baseline factors associated with HCV reinfection.
Results
A total of 216 HIV-positive and 1589 reference patients were recruited with median follow-up durations of 3.0 and 6.0 years. During a total of 772 person-years of follow-up (PYFU), the HCV reinfection rate in HIV-positive patients was 4.02 per 100 PYFU (95% confidence interval [CI]: 2.85-5.65), while the HCV reinfection rate in reference patients was 0.14 per 100 PYFU (95% CI: 0.09-0.23) during 10862 PYFU. HIV-positive patients had a higher risk of HCV reinfection than reference patients (hazard ratio [HR]: 17.63; 95% CI: 7.10-43.80, p < 0.001). No baseline factors were predictive of HCV reinfection in HIV-positive patients. The incidence of HCV reinfection in HIV-positive patients increased after 2015 when DAAs were available in Taiwan.
Conclusions
The risk of HCV reinfection remains high in HIV/HCV-coinfected patients with treatment-induced SVR12. In addition to mass screening and treatment scale-up, strategies to reduce reinfection are needed for HCV microelimination in HIV-positive patients in Taiwan.
