Davey S, Costello K, Russo M, Davies S, Lalani HS, Kesselheim AS, Rome BN. Changes in Use of Hepatitis C Direct-Acting Antivirals After Access Restrictions Were Eased by State Medicaid Programs. JAMA HEALTH FORUM 2024; 5:e240302. [PMID: 38578628 PMCID: PMC10998155 DOI: 10.1001/jamahealthforum.2024.0302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Accepted: 02/02/2024] [Indexed: 04/06/2024] Open
Abstract
Importance Direct-acting antivirals (DAAs) are safe and highly effective for curing hepatitis C virus (HCV) infection, but their high cost led certain state Medicaid programs to impose coverage restrictions. Since 2015, many of these restrictions have been lifted voluntarily in response to advocacy or because of litigation. Objective To estimate how the prescribing of DAAs to Medicaid patients changed after states eased access restrictions. Design, Setting, and Participants This modified difference-in-differences analysis of 39 state Medicaid programs included Medicaid beneficiaries who were prescribed a DAA from January 1, 2015, to December 31, 2019. DAA coverage restrictions were measured based on a series of cross-sectional assessments performed from 2014 through 2022 by the US National Viral Hepatitis Roundtable and the Center for Health Law and Policy Innovation. Exposure Calendar quarter when states eased or eliminated 3 types of DAA coverage restrictions: limiting treatment to patients with severe liver disease, restricting use among patients with active substance use, and requiring prescriptions to be written by or in consultation with specialists. States with none of these restrictions at baseline were excluded. Main Outcomes and Measures Quarterly number of HCV DAA treatment courses per 100 000 Medicaid beneficiaries. Results Of 39 states, 7 (18%) eliminated coverage restrictions, 25 (64%) eased restrictions, and 7 (18%) maintained the same restrictions from 2015 to 2019. During this period, the average quarterly use of DAAs increased from 669 to 3601 treatment courses per 100 000 Medicaid beneficiaries. After states eased or eliminated restrictions, the use of DAAs increased by 966 (95% CI, 409-1523) treatment courses per 100 000 Medicaid beneficiaries each quarter compared with states that did not ease or eliminate restrictions. Conclusions and Relevance The results of this study suggest that there was greater use of DAAs after states relaxed coverage restrictions related to liver disease severity, sobriety, or prescriber specialty. Further reductions or elimination of these rules may improve access to a highly effective public health intervention for patients with HCV.

Self-reported and measured adherence to hepatitis C direct-acting antiviral therapy and sustained virologic response among people who inject drugs: The HERO study. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024; 123:104288. [PMID: 38103458 DOI: 10.1016/j.drugpo.2023.104288] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 11/30/2023] [Accepted: 12/02/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND Objective adherence measures, such as electronic blister pack (BP), for direct-acting antivirals (DAAs) for hepatitis C virus (HCV) treatment have high accuracy, but their use is limited in real practice settings. We examined the association of self-reported adherence using a visual analogue scale (VAS) with objective BP adherence and sustained virologic response (SVR) among people who inject drugs. METHODS We conducted secondary analyses using a subset of participants (N = 493) from the per-protocol sample of the HERO study, a pragmatic randomized trial of HCV treatment interventions that used both VAS and BP to measure adherence to a 12-week sofosbuvir/velpatasvir DAA regimen. Multivariable mixed-effects regression models tested the association of self-report adherence level with longitudinal weekly objective adherence. Multivariable logistic regression tested the association of self-report adherence with SVR. RESULTS The average VAS and BP adherences were 95.1 % (SD = 8.9 %) and 76.0 % (16.0 %), respectively, and the proportion of the participants achieving SVR was 92.9 %. The estimated adjusted mean objective adherence was significantly different (-16 %; 95 % CI: -22 %, -11 %, p < .001) between participants with 100 % and <80 % VAS adherence. The likelihood of SVR was significantly lower for those with <80 % VAS adherence [adjusted OR = 0.07; 95 % CI: 0.02, 0.24; p < .001] compared to those with 100 %. CONCLUSION Self-reported adherence overestimated objective adherence. However, higher self-report adherence was significantly associated with higher objective adherence. Also, self-reported adherence ≥80 % was significantly associated with SVR. Thus, the self-report measure has utility as a monitoring tool for adherence during DAA treatment.

Abstract
OBJECTIVE Treatment for hepatitis C virus (HCV) infection is highly effective; however, people who inject drugs (PWID), the population most affected by HCV, may encounter barriers to treatment. We examined the cascade of care for HCV infection among young adult PWID in northern New Mexico, to help identify gaps and opportunities for HCV treatment intervention. METHODS Young adults (aged 18-29 y) who self-reported injection drug use in the past 90 days were tested for HCV antibodies (anti-HCV) and HCV RNA. We asked participants with detectable RNA to participate in an HCV education session, prior to a referral to a local health care provider for treatment follow-up, and to return for follow-up HCV testing quarterly for 1 year. We measured the cascade of care milestones ranging from the start of screening to achievement of sustained virologic response (SVR). RESULTS Among 238 participants, the median age was 26 years and 133 (55.9%) were men. Most (90.3%) identified as Hispanic. Of 109 RNA-positive participants included in the cascade of care assessment, 84 (77.1%) received their results, 82 (75.2%) participated in the HCV education session, 61 (56.0%) were linked to care through a medical appointment, 27 (24.8%) attended the HCV treatment appointment, 13 (11.9%) attended their follow-up appointment, 6 (5.5%) initiated treatment, 3 (2.8%) completed treatment, and 1 (0.9%) achieved SVR. CONCLUSIONS We observed a steeply declining level of engagement at each milestone step of the cascade of care after detection of HCV infection, resulting in a suboptimal level of HCV treatment and cure. Programs that can streamline testing and expand access to treatment from trusted health care providers are needed to improve the engagement of PWID in HCV treatment.

Abstract
In our Boston-based outpatient parenteral antibiotic therapy (OPAT) program between 2016 and 2021, we found that a low proportion of patients with active hepatitis C virus (HCV) were prescribed HCV treatment by their OPAT provider and few achieved sustained virologic response. Clinicians should consider concurrent HCV treatment during OPAT.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 113:103959.

Abstract
BACKGROUND & AIMS Directly observed therapy (DOT) maximizes adherence and minimizes treatment gaps. Peer case managers (PCM) have also shown promise as a component of integrated HCV treatment strategies. DOT and PCM-support have been underexplored, particularly in low- and middle-income countries (LMICs). The objective of this study was to evaluate predictors of sustained virologic response (SVR) among people who inject drugs (PWID) attending medication-assisted treatment (MAT) and needle and syringe programs (NSP) sites in Kenya. METHODS We recruited PWID accessing MAT and NSP in Nairobi and Coastal Kenya. PWID were treated with ledipasvir/sofosbuvir using DOT supported by PCMs. We used bivariate and multivariate logistic regression to examine the impact of sociodemographic, behavioral, and clinical factors on SVR. RESULTS Among 92 PWID who initiated HCV treatment, 79 (86%) were male with mean age of 36.3 years (SD=±6.5); 38 (41%) were HIV-positive, and 87 (95%) reported injecting drugs in the last 30 days. Just over half of participants were genotype 1a (55%), followed by genotype 4a (41%) and mixed 1a/4a (3%). Most participants, 85 (92%) completed treatment and 79 (86%) achieved SVR. While sociodemographic and behavioral factors including recent injection drug use were not significantly associated with achieving SVR, being fully adherent (p=0.042), number of doses taken (p=0.008) and treatment completion (p= 0.001) were associated with higher odds of achieving SVR. CONCLUSIONS DOT with PCM-support was an effective model for HCV treatment among PWID in this LMIC setting. Adherence was the most important driver of SVR suggesting DOT and PCM support can overcome other factors that might limit adherence. Further research is necessary to ascertain the effectiveness of other models of HCV care for PWID in LMICs given NSP and MAT access is variable, and DOT may not be sustainable with limited resources.

Abstract
Hepatitis C virus (HCV) is one of the leading causes of liver disease and is responsible for massive health and economic burden worldwide. The disease is asymptomatic in its early stages, but it can progress over time to fatal end-stage liver disease. Thus, the majority of individuals infected with HCV are unaware of their chronic condition. Recent treatment options for HCV can completely cure the infection but are costly. We developed a game model between a pharmaceutical company (PC) and a country striving to maximize its citizens' utility. First, the PC determines the price of HCV treatment; then, the country responds with corresponding screening and treatment strategies. We employed an analytical framework to calculate the utility of the players for each selected strategy. Calibrated to detailed HCV data from Israel, we found that the PC will gain higher revenue by offering a quantity discount rather than using standard fixed pricing per treatment, by indirectly forcing the country to conduct more screening than it desired. By contrast, risk-sharing agreements, in which the country pays only for successful treatments are beneficial for the country. Our findings underscore that policy makers worldwide should prudently consider recent offers by PCs to increase screening either directly, via covering HCV screening, or indirectly, by providing discounts following a predetermined volume of sales. More broadly, our approach is applicable in other healthcare settings where screening is essential to determine treatment strategies.

Abstract
Integrated care and cooperation between service providers optimize the HCV care continuum among people who inject drugs. Results suggest that people who inject drugs with HCV infection can be effectively linked and treated with direct-acting antivirals regimens in settings outside of hospital. Interventions that facilitate HCV care must be implemented at settings where people who inject drugs are already accessing services. The experts' reflections complement the findings of the literature review and inform public health practice by considering the heterogeneity of health systems and national regulatory frameworks. Higher quality studies investigating interventions addressing the entire care cascade from testing to cure and prevention of reinfections among highly vulnerable populations are urgently needed.

Abstract
Introduction: Hepatitis C (HCV) is viral disease with a global impact. Over the last 10 years, the treatment of this disease has evolved. Treatment guidelines have evolved to adopt new medications for HCV. These drugs have shown efficacy over 90% throughout the class as well as a better safety profile than the previous recommended pharmacotherapy. Dual-therapy DAAs emerged with FDA approval of Ledipasvir/Sofosbuvir (LDV/SOF) in 2014.Areas Covered: LDV/SOF is a dual-therapy option for chronic HCV patients (>6 months of infection) in select genotypes. This article reviews the studies relevant to the pharmacokinetic/pharmacodynamic properties of these drugs as well as its trials leading to approval.Expert opinion: LDV/SOF is included in the AASLD/IDSA guidelines for the treatment of HCV genotypes 1a and 1b with or without cirrhosis and genotype 4 without cirrhosis with an evidence and recommendation rating of IA. Genotype 4 with cirrhosis and genotypes 5 and 6 carry a Class IIa level B recommendation. The combination is not FDA approved for genotypes 2 and 3. Single-pill regimens, like LDV/SOF, are important to maintain the quality of life of children and other special populations infected with HCV by shortening treatment regimens, avoiding complex pill regimens, and eliminating injection therapies.

Abstract
BACKGROUND AND AIMS Limited data is available on the efficacy of direct acting anti-viral drugs on hepatitis C in drug users. The aim of this meta-analysis was to comprehensively analyze the efficacy and safety of LDV/SOF in drug users infected with the hepatitis C virus (HCV). METHODS The PubMed, Cochrane library, Embase and Web of Science databases were searched for articles published till April 2021 on HCV-positive drug users who were treated with ledipasvir/sofosbuvir (LDV/SOF). The primary endpoint was pooled sustained virological response at 12 weeks (SVR12) with 95% confidence interval (95% CI). Funnel plots and Egger's test were used to assess the publication bias. RESULTS A total of 12 studies and 711 subjects treated with LDV/SOF-based regimen for HCV were included, and the pooled SVR12 rate was 89.8% (95% CI 85.9-92.7). The pooled SVR12 rate of genotype 1 drug users was 92.4% (95% CI 88.6-95.0). Subgroup analysis showed that pooled SVR12 rates of patients treated with LDV/SOF and LDV/SOF ± RBV were 89.2% (95% CI 83.4-93.1), 90.4% (95% CI 83.6-94.5) respectively. In addition, the SVR12 rates were 88% (95% CI 70.7-95.7) for 8 weeks, 89.9% (95% CI 81.0-94.9) for 12 weeks and 82.2% (95% CI 24.9-98.5) for 24 weeks of treatment. CONCLUSION LDV/SOF is a safe and relatively effective treatment for hepatitis C in drug users.

Abstract
Hepatitis C virus (HCV) affects over 70 million people globally, with an estimated 399 000 HCV-related deaths in 2016. The World Health Organization (WHO) has set a goal to eliminate HCV by 2030. Despite the availability of direct-acting antivirals-highly effective and well-tolerated therapies for HCV-many patients infected with HCV in Germany have not initiated treatment, including a majority of those who are aware of their positive diagnosis. Barriers to screening, diagnosis, and treatment are major factors taking many countries off track for HCV elimination by 2030. Identifying country-specific barriers and challenges, particularly in at-risk populations such as people who inject drugs or men who have sex with men, has the potential to create tailored programs and strategies to increase access to screening or treatment and engage at-risk populations. This review aims to report the current steps toward HCV elimination in Germany, the country-specific barriers and challenges that will potentially prevent reaching the 2030 HCV elimination goal and describe good practice examples to overcome these barriers.

Promoting treatment for hepatitis C in people who inject drugs: A review of the barriers and opportunities. J Am Assoc Nurse Pract 2021; 32:563-568. [PMID: 31425374 DOI: 10.1097/jxx.0000000000000269] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/15/2022]
Abstract
BACKGROUND People who inject drugs (PWIDs) comprise a significant amount of the population who are also positive for hepatitis C virus (HCV) around the world. Even though there is evidence that patients who currently inject drugs do not display altered treatment adherence or medication effectiveness, health care providers are still hesitant to treat this patient population based on perceived threats and barriers. OBJECTIVES This literature review informs of the perceived barriers associated with PWID in receiving HCV treatment and supports recommendations to address these barriers. DATA SOURCES For this review, eight scholarly articles rated levels I A through II B using John Hopkins Evidence-Based Practicing ratings consisting of randomized controlled trials, systematic reviews, and meta-analyses were selected. Both qualitative and quantitative data contributed to identifying perceived barriers and suggested course of action that should be taken to increase HCV treatment uptake among PWID. CONCLUSIONS The three main perceived barriers are evidence of barriers to treatment in the PWID populations and include increased risk of reinfection, low adherence to treatment, and decreased response to treatment. Removal of these barriers by increasing education about HCV disease and treatment options to both patients and health care workers and changing current policy in health care settings to provide enhanced access to HCV treatment for PWID can promote an opportunity for successful treatment of these patients. IMPLICATIONS FOR PRACTICE There is a significant need for HCV treatment among PWID. Opportunities for successful treatment exist and should be adopted.

Abstract
The opioid epidemic in the United States, along with a lack of adequate harm reduction services, has contributed to a sharp rise in hepatitis C virus (HCV) infections. Despite considerable evidence of the effectiveness of HCV treatment in people who inject drugs (PWID), and recommendations from clinical guidelines to prioritize treatment in PWID, there are multiple barriers to broad uptake of HCV treatment. These barriers exist at the systems level, as well as at the level of medical providers and patients. Interventions to remove treatment barriers in the United States include harm reduction services, simplifying HCV testing algorithms, improved linkage to HCV care services, and application of new treatment models including colocating services at substance use disorder treatment programs. By following the lead of other countries who have addressed the barriers to HCV treatment, the United States has opportunities to do better in addressing the consequences of the opioid epidemic, including chronic HCV infection.

Evolution of Hepatitis C Virus Treatment During the Era of Sofosbuvir-Based Therapies: A Real-World Experience in France. Dig Dis Sci 2021; 66:881-898. [PMID: 32303953 DOI: 10.1007/s10620-020-06234-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2018] [Accepted: 03/24/2020] [Indexed: 12/09/2022]
Abstract
BACKGROUND Treatment of hepatitis C virus (HCV) has been dramatically improved with the introduction of direct-acting antiviral agents (DAAs). Universal access to pangenotypic DAAs was provided in France from 2017, expanding the type of patients treated. Real-world studies are important to confirm effectiveness and safety in clinical practice, particularly in vulnerable populations. AIMS To assess real-world effectiveness and safety of sofosbuvir-based therapy in adults with chronic HCV infection before and after universal access to DAAs in France. METHODS This multicenter, non-interventional, prospective study assessed the effectiveness, safety, patient-reported outcomes and adherence with sofosbuvir-based regimens from October 2015 to July 2016 (Period 1: sofosbuvir-based therapy excluding sofosbuvir/velpatasvir) and from October 2017 to July 2018 (Period 2: pangenotypic sofosbuvir/velpatasvir-based therapy). RESULTS Baseline data were documented for 1029 patients. Overall, 797 (77%) had sustained virologic response data available ≥ 9 weeks after treatment completion. Per protocol response was high (97%) irrespective of age, alcohol consumption, recreational drug use, or HIV/HCV coinfection. Adverse events occurred in approximately 25% of patients with the majority experiencing Grade 1 or 2 events. Sofosbuvir-based regimens improved health-related quality of life from baseline to end of treatment in patients with data at all timepoints. Overall, 99% of patients reported total or almost total adherence to therapy. CONCLUSIONS Sofosbuvir-based therapy, including pangenotypic sofosbuvir/velpatasvir, is effective for the treatment of HCV in real-world clinical practice. This is an important step towards HCV elimination.

J Manag Care Spec Pharm 2021; 27:263-267. [PMID: 33506724 PMCID: PMC10391126 DOI: 10.18553/jmcp.2021.27.2.263] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/05/2022]
Abstract
BACKGROUND: In 2019, the Utilization Review Accreditation Commission (URAC) required a new reporting measure for specialty pharmacies related to completion of therapy for hepatitis C virus (HCV). OBJECTIVE: To calculate HCV completion of therapy according to URAC criteria and compare it with a calculation with additional pharmacy proposed adjustments to assess its applicability. METHODS: This was an observational study of patients who received HCV treatment with a direct-acting antiviral (DAA) from 1 specialty pharmacy. All patients with prescription claims at a pharmacy who had a first fill for a DAA medication between the 2 measurement periods of January 1, 2018-December 31, 2018, and January 1, 2019-December 31, 2019, were included. Additional information was collected via a retrospective chart review and from the pharmacy's electronic medication system. The cumulative gap according to URAC was calculated from claims data by summing the number of days between the last days supply of 1 claim for the prescribed DAA and the subsequent claims. The pharmacy-proposed cumulative gap was calculated using additional information from patient chart notes in order to account for a true start date. RESULTS: A total of 1,485 patients were identified as having a first fill of a DAA between the 2 measurement periods. The HCV completion of therapy measure calculated per the URAC definition was 83.4% in 2018 and 86.5% in 2019. The only variable significantly associated with a > 15-day gap according to the URAC definition was if the first DAA order was delivered to the prescriber's office instead of the patient's home for 2018 (χ2 [1, N = 573] = 16.8, P < 0.001) and 2019 (χ2 [1, N = 836] = 12.6, P < 0.001). Using the pharmacy-proposed adjustment, the modified HCV completion rates for 2018 and 2019 were 88.9% and 89.9%, respectively. CONCLUSIONS: The accrediting body's definition of completion of therapy may report a falsely high rate of gaps in HCV therapy due to not accounting for the actual DAA start date. This information may prove beneficial for the accrediting body, as it reviews its initial definition of the HCV completion of therapy measure. DISCLOSURES: No outside funding supported this study. Levesque reports participation in AbbVie's speaker's bureau with regard to its immunology portfolio. The other authors have no possible financial or personal relationships with commercial entities to disclose that may have a direct or indirect interest in the matter of this study.

Abstract
BACKGROUND Treatment uptake for hepatitis C virus (HCV) infection in people who inject drugs (PWID) and patients on opioid substitution therapy (OST) is still low despite treatment guidelines that advocate the use of direct-acting antivirals (DAAs) in all patients. Our aim in this review was to investigate treatment outcomes among PWID and patients on OST in comparison to control cohorts. METHODS A search of Embase, Medline, PubMed, and Web of Science (from October 2010 to March 2018) was conducted to assess sustained virologic response (SVR), discontinuation rates, adherence, and HCV reinfection in PWID and patients on OST. RESULTS We identified 11 primary articles and 12 conference abstracts comprising 1702 patients on OST, 538 PWID, and 19 723 patients who served as controls. Among patients on OST, the pooled SVR was 90% (95% confidence interval [CI], 87% to 93%) and pooled treatment discontinuation rate was 7% (95% CI, 4% to 11%). Similarly, the pooled SVR was 88% (95% CI, 80% to 93%) in PWID and the pooled treatment discontinuation rate was 9% (95% CI, 5% to 15%). There was no significant difference regarding pooled rates of SVR, adherence, and discontinuation between patients on OST and controls as well as between PWID and controls. HCV reinfection rates among patients on OST ranged from 0.0 to 12.5 per 100 person-years. CONCLUSIONS HCV treatment outcomes in PWID and patients on OST are similar to those in patients without a history of injecting drugs, supporting current guideline recommendations to treat HCV in these patient populations.

Abstract
BACKGROUND Hepatitis C virus treatment in persons who use drugs (PWUD) is often withheld due to adherence and reinfection concerns. In this study, we report treatment outcomes, technology-based adherence data, and adherence predictors in PWUD and/or alcohol. METHODS INCLUD was a prospective, open-label study of ledipasvir/sofosbuvir for 12 weeks in PWUD aged 18-70 years. Participants were randomized to wireless (wirelessly observed therapy) or video-based directly observed therapy (vDOT). Drug use was assessed every 2 weeks. Sustained virologic response (SVR) was examined by intention-to-treat and as-treated. Factors associated with missing ≥1 dose(s) between visits were examined using generalized linear models. RESULTS Sixty participants received ≥1 ledipasvir/sofosbuvir dose (47 human immunodeficiency virus [HIV]/hepatitis C virus [HCV], 13 HCV only; 78% male; 22% black; 25% cirrhotic). Substance use occurred at 94% of person-visits: 60% marijuana, 56% alcohol, 37% methamphetamine, 22% opioids, 17% cocaine, and 20% injection drug use. The SVR by intention-to-treat was 86.7% (52 of 60) and as-treated was 94.5% (52 of 55). Confirmed failures included 1 relapse, 1 reinfection, and 1 unknown (suspected reinfection). Median total adherence was 96% (interquartile range [IQR], 85%-100%; range, 30%-101%), and between-visit adherence was 100% (IQR, 86%-100%; range, 0%-107%). The odds of missing ≥1 dose between visits increased with HIV coinfection (2.94; 95% confidence interval [CI], 1.37-6.32; P = .006), black race (4.09; 95% CI, 1.42-11.74; P = .009), methamphetamine use (2.51; 95% CI, 1.44-4.37; P = .0.001), and cocaine use (2.12; 95% CI, 1.08-4.18; P = .03) and decreased with marijuana use (0.34; 95% CI, 0.17-0.70; P = .003) and vDOT (0.43; 95% CI, 0.21-0.87; P = .02). CONCLUSIONS Persons who use drugs achieved high SVR rates with high, but variable, ledipasvir/sofosbuvir adherence using technology-based methods. These findings support efforts to expand HCV treatment in PWUD.

Abstract
BACKGROUND Direct-acting antivirals (DAAs) are recommended for the treatment of hepatitis C virus (HCV) infection in patients treated with methadone or buprenorphine.
AIM To assess HCV treatment rates in an Opioid Treatment Program (OTP).
METHODS This longitudinal study included 501 patients (81.4% men, median age: 45 years; interquartile range: 39-50 years) enrolled in an OTP between October 2015 and September 2017. Patients were followed until September 2019. Data on socio-demographics, substance use, HCV infection, human immunodeficiency virus (HIV) infection and laboratory parameters were collected at entry. We analyzed medical records to evaluate HCV treatment. Kaplan-Meier methods and Cox regression models were used to analyze the DAA treatment uptake and to identify treatment predictors.
RESULTS Prevalence of HCV and HIV infection was 70% and 34%, respectively. Among anti-HCV-positive (n = 336) patients, 47.2%, 41.3%, and 31.9% used alcohol, cannabis, and cocaine, respectively. HCV-RNA tests were positive in 233 (69.3%) patients. Twentyeight patients (8.3%) cleared the infection, and 59/308 (19.1%) had received interferon-based treatment regimens before 2015. Among 249 patients eligible, 111 (44.6%) received DAAs. Treatment rates significantly increased over time from 7.8/100 person-years (p-y) (95%CI: 5.0-12.3) in 2015 to 18.9/100 p-y (95%CI: 11.7-30.3) in 2019. In a multivariate analysis, patients with HIV co-infection were twice as likely to receive DAAs (HR = 1.94, 95%CI: 1.21-3.12) than patients with HCV mono-infection. Current drug use was an independent risk factor for not receiving treatment against infection (HR = 0.48, 95%CI: 0.29-0.80).
CONCLUSION HCV treatment is evolving in patients with HCV-HIV co-infection. Ongoing drug use while in an OTP might negatively impact the readiness to treat infection.

Abstract
Hepatitis C virus (HCV) infection is a silent killer that leads to rapid progression of liver cirrhosis and hepatocellular carcinoma (HCC). High prevalence of HCV infection has been reported in Taiwan, especially in high-risk populations including people who inject drugs (PWID) and patients requiring dialysis. Besides, certain populations merit special considerations due to suboptimal outcome, potential drug-drug interaction, or possible side effect. Therefore, in the second part of this 2-part consensus, the Taiwan Association for the Study of the Liver (TASL) proposes the treatment recommendations for the special population in order to serve as guidance to optimizing the outcome in the direct-acting antiviral (DAA) era. Special populations include patients with acute or recent HCV infection, previous DAA failure, chronic kidney disease, decompensated cirrhosis, HCC, liver and other solid organ transplantations, receiving an HCV viremic organ, hepatitis B virus (HBV) and HCV dual infection, HCV and human immunodeficiency virus (HIV) coinfection, active tuberculosis infection, PWID, bleeding disorders and hemoglobinopathies, children and adolescents, and pregnancy. Moreover, future perspectives regarding the management of hepatitis C are also discussed and summarized in this consensus statement.

Abstract
BACKGROUND & AIMS Adequate adherence to hepatitis C virus (HCV) treatment is believed to be a key component of treatment success because non-adherence can potentially result in treatment failure and the emergence of resistant viral variants. This analysis assessed factors associated with non-adherence to glecaprevir/pibrentasvir (G/P) therapy and the impact of non-adherence on sustained virological response at post-treatment week 12 (SVR12) rates in HCV genotype (GT) 1-6-infected patients. METHODS Adherence was calculated by pill counts at study visits during treatment, and defined as having a lowest treatment adherence of ≥80% and ≤120% at each study visit. Exploratory logistic regression modelling assessed predictors of non-adherence to G/P therapy. SVR12 rates by treatment adherence were assessed in the intent-to-treat (ITT) population and modified ITT (mITT) population, which excludes non-virological failures. RESULTS Overall, 97% (2024/2091) of patients were adherent to G/P therapy at all consecutive study visits. Alcohol use was the only baseline characteristic independently associated with non-adherence to G/P therapy (OR: 2.38; 95% CI: 1.13-5.01; P = .022). In the mITT population, overall SVR12 rates were high both in patients who were adherent to G/P therapy and those who were not (99% [1983/2008] and 95% [58/61] respectively; P = .047). Corresponding SVR12 rates in the ITT population were 98% (1983/2024) and 87% (58/67) respectively. CONCLUSIONS Most patients adhered to G/P therapy. SVR12 rates were high both in patients who were adherent to G/P treatment and those who were not. Patient education on treatment adherence should remain an important part of HCV treatment.

Abstract
Background Direct-acting antivirals (DAAs) offer high cure rates in people who inject drugs (PWID) with hepatitis C virus (HCV) infection. There are concerns regarding lower response rates among PWID in real life. We evaluated the outcome of DAA therapy in PWID in a real-world setting and the factors that affect it. Methods We performed a retrospective analysis of 174 PWID with chronic hepatitis C who started DAAs in a Greek liver clinic in collaboration with an addiction program. Patients who did not return for reassessment were considered as lost to follow up (LTFU). A logistic regression model was used to assess factors associated with a sustained virological response 12 weeks after treatment completion (SVR12) and LTFU. Results Patients' mean age was 48±9.2 years and 91/174 (52.3%) were attending opioid substitution treatment programs. Overall, 144/174 (82.8%) patients completed therapy and presented for SVR12 testing, 8/174 (4.6%) did not complete treatment and 22/174 (12.6%) were LTFU. Overall SVR12 was 79.9% (139/174). For those with an available SVR12 test the response rate reached 96.5% (139/144). Regression analysis did not indicate any significant association between patient characteristics and SVR12. Age <45 years and genotype 3 were independent predictors of LTFU. Parallel use was found to have a trend towards LTFU. Conclusions HCV treatment by hepatologists and addiction specialists is feasible, effective and safe in a real-world setting. However, as 12% of patients appear to be LTFU, more emphasis should be placed on interventions guaranteeing follow up for SVR testing and general care.

Abstract
BACKGROUND Recent approval and adoption of pangenotypic direct acting antivirals (DAAs) necessitated a revision of the 2015 World Health Organization guidelines for the management of persons with hepatitis C virus (HCV) infection. METHODS We searched MEDLINE, EMBASE, CENTRAL, and relevant conference proceedings to identify randomized and non-randomized trials, as well as prospective observational studies of DAAs. The proportions of persons with events were pooled for sustained virological response at 12 weeks post-treatment (SVR12), discontinuations due to adverse events (DAEs), serious adverse events (SAEs), and all-cause mortality. Analyses were stratified by HCV genotype and antiviral treatment experience, with subgroup analyses based on presence of cirrhosis and HIV-HCV coinfection. FINDINGS The evidence base consisted of 238 publications describing 142 studies. In the overall analysis, which included all persons irrespective of treatment experience or comorbidities, the pooled proportion achieving SVR12 exceeded 0.94 for all pangenotypic regimens across genotypes 1, 2, and 4. Some heterogeneity may have led to lower SVR rates in persons with genotype 3 infection. High SVR12 (>0.90) was observed in persons with genotype 1 infection with cirrhosis, though evidence varied and was limited for genotypes 2-4. Evidence was sparse for persons with HIV-HCV coinfection. All regimens were associated with small proportions of persons with DAEs, SAEs, or all-cause mortality. INTERPRETATION Based on this and other supporting evidence, the WHO issued updated guidelines with a conditional recommendation, based on moderate quality evidence, for the use of pangenotypic DAA regimens for persons with chronic HCV infection aged 18 years and older (July 2018). FUNDING This study was funded by the World Health Organization.

Abstract
BACKGROUND AND AIMS Direct-acting antivirals (DAAs) are highly effective in treating hepatitis C. However, there is concern that cure rates may be lower, and reinfection rates higher, among people who inject drugs. We conducted a systematic review of treatment outcomes achieved with DAAs in people who inject drugs (PWID). METHODS A search strategy was used to identify studies that reported sustained viral response (SVR), treatment discontinuation, adherence or reinfection in recent PWID and/or opioid substitution therapy (OST) recipients. Study quality was assessed using the Newcastle-Ottawa Scale. Meta-analysis of proportions was used to estimate pooled SVR and treatment discontinuation rates. The pooled relative risk of achieving SVR and pooled reinfection rate were calculated using generalized mixed effects linear models. RESULTS The search identified 8075 references; 26 were eligible for inclusion. The pooled SVR for recent PWID was 88% (95% CI, 83%-92%) and 91% (95% CI 88%-95%) for OST recipients. The relative risk of achieving SVR for recent PWID compared to non-recent PWID was 0.99 (95% CI, 0.94-1.06). The pooled treatment discontinuation was 2% (95% CI, 1%-4%) for both recent PWID and OST recipients. Amongst recent PWID, the pooled incidence of reinfection was 1.94 per 100 person years (95% CI, 0.87-4.32). In OST recipients, the incidence of reinfection was 0.55 per 100 person years (95% CI, 0.17-1.76). CONCLUSIONS Treatment outcomes were similar in recent PWID compared to non-PWID treated with DAAs. People who report recent injecting or OST recipients should not be excluded from hepatitis C treatment.

Abstract
Abstract
Background
This study investigated adherence and associated factors among people with recent injection drug use (IDU) or current opioid agonist therapy (OAT) and compared once-daily to twice-daily hepatitis C virus (HCV) direct-acting antiviral (DAA) therapy.
Methods
SIMPLIFY and D3FEAT are international, multicenter studies that recruited participants with recent IDU (previous 6 months; SIMPLIFY, D3FEAT) or current OAT (D3FEAT) between March 2016 and February 2017 in 8 countries. Participants received sofosbuvir/velpatasvir (once daily; SIMPLIFY) or paritaprevir/ritonavir/ombitasvir, dasabuvir (twice daily) ± ribavirin (D3FEAT) for 12 weeks administered in electronic blister packs. We evaluated overall adherence (proportion of prescribed doses taken) and nonadherence (<90% adherent) between dosing patterns.
Results
Of 190 participants, 184 (97%) completed treatment. Median adherence was 92%, with higher adherence among those receiving once-daily vs twice-daily therapy (94% vs 87%, P = .005). Overall, 40% of participants (n = 76) were nonadherent (<90% adherent). Recent stimulant injecting (odds ratio [OR], 2.48 [95% confidence interval {CI}, 1.28–4.82]), unstable housing (OR, 2.18 [95% CI, 1.01–4.70]), and twice-daily dosing (OR, 2.81 [95% CI, 1.47–5.36]) were associated with nonadherence. Adherence decreased during therapy. Sustained virologic response was high in nonadherent (89%) and adherent populations (95%, P = .174), with no difference in SVR between those who did and did not miss 7 consecutive doses (92% vs 93%, P = .897).
Conclusions
This study demonstrated high adherence to once- and twice-daily DAA therapy among people with recent IDU or currently receiving OAT. Nonadherence described did not impact treatment outcomes, suggesting forgiveness to nonadherence.

Abstract
A community-based public health facility in Sydney, Australia, the Kirketon Road Centre (KRC), provides health care to people who inject drugs (PWID), homeless and other marginalized people. Since March 2016, KRC has provided treatment for chronic hepatitis C virus (HCV) with direct-acting antivirals (DAAs). We aimed to evaluate treatment adherence amongst clients taking DAAs in a highly marginalized population. All clients who commenced DAA therapy prior to March 2018 at KRC were included in this observational cohort with a subset of clients attending daily or weekly for enhanced adherence support and dosing. Demographic, behavioural, clinical measures and medication dosing were recorded, and adherence was calculated as the proportion of doses taken during the expected treatment duration. Factors associated with adherence were examined using logistic regression. A total of 242 individuals commenced DAA therapy, of whom 79 (32%) received enhanced adherence support. Enhanced support was associated with homelessness, daily injecting, Aboriginality, mental health co-morbidity and poly-drug use (all P < .001). Overall adherence was 86%, and 92% of patients missed one or more doses (median 10, IQR 4-24). At least 90% adherence during planned duration was seen in 38%, but increased to 66% by continuing therapy beyond planned duration. Intention-to-treat SVR12 was 68% and 66% in the enhanced adherence support sub-population, with 29% lost to follow-up by SVR12 testing. There were only 2 (0.8%) documented virological failures. Per-protocol SVR12 was 99% and 96% in the enhanced adherence support sub-population. In conclusion, adherence support may benefit those with multiple markers of marginalization. Extension of therapy beyond planned duration is a pragmatic strategy to enhance completion. Strategies to improve follow-up, particularly post-treatment are required.

Abstract
It has been estimated by the World Health Organization (WHO) that over 71 million people were infected with the hepatitis C virus (HCV) in 2015. Since then, a number of highly effective direct-acting antiviral (DAA) regimens have been licensed for the treatment of chronic HCV infection: sofosbuvir/daclatasvir, sofosbuvir/ledipasvir, elbasvir/grazoprevir, sofosbuvir/velpatasvir, glecaprevir/pibrentasvir, and sofosbuvir/velpatasvir/voxilaprevir. With these treatment regimens, almost all chronic HCV-infected patients, even including prior DAA failures, can be treated effectively and safely. It is therefore likely that further development of DAAs will be limited. In this descriptive review we provide an overview of the clinical pharmacokinetic characteristics of currently available DAAs by describing their absorption, distribution, metabolism, and excretion. Potential drug-drug interactions with the DAAs are briefly discussed. Furthermore, we summarize what is known about the pharmacodynamics of the DAAs in terms of efficacy and safety. We briefly discuss the relationship between the pharmacokinetics of the DAAs and efficacy or toxicity in special populations, such as hard to cure patients and patients with liver cirrhosis, liver transplantation, renal impairment, hepatitis B virus or HIV co-infection, bleeding disorders, and children. The aim of this overview is to educate/update prescribers and pharmacists so that they are able to safely and effectively treat HCV-infected patients even in the presence of underlying co-infections or co-morbidities.

Abstract
Opioid use in the United States and in many parts of the world has reached epidemic proportions. This has led to excess mortality as well as significant changes in the epidemiology of liver disease. Herein, we review the impact of the opioid epidemic on liver disease, focusing on the multifaceted impact this epidemic has had on liver disease and liver transplantation. In particular, the opioid crisis has led to a significant shift in incident hepatitis C virus infection to younger populations and to women, leading to changes in screening recommendations. Less well characterized are the potential direct and indirect hepatotoxic effects of opioids, as well as the changes in the incidence of hepatitis B virus infection and alcohol abuse that are likely rising in this population as well. Finally, the opioid epidemic has led to a significant rise in the proportion of organ donors who died due to overdose. These donors have led to an overall increase in donor numbers, but also to new considerations about the better use of donors with perceived or actual risk of disease transmission, especially hepatitis C. Clearly, additional efforts are needed to combat the opioid epidemic. Moreover, better understanding of the epidemiology and underlying pathophysiology will help to identify and treat liver disease in this high-risk population.

Abstract
Direct-Acting Antiviral (DAA) treatments for hepatitis C have been widely promoted by health promotion professionals and medical clinicians as being 'side-effect free'. In this paper, we draw on data that troubles this approach. We used a mixed method design to collect data from people who inject drugs, and who were DAA treatment naïve, in New South Wales, Australia. We describe knowledge about and perceptions of DAA treatment. We found that concerns about side effects were commonplace - for example, one-third (37%) of participants who had not taken up treatment worried "a lot" about 'side effects' - and that these concerns were underpinned by a general distrust and suspicion of medical institutions and their technologies, including widespread negative associations linked to interferon treatment. In trying to make sense of this, we draw on the concept of counterpublic health and its recognition that the everyday health needs, knowledges and aspirations of subordinated citizens frequently contradict the normative frameworks governing public health interventions. We suggest that failing to engage with concerns about 'side effects' could hinder elimination efforts. Our analysis suggests that addressing the issue of 'side effects' within the 'public' discourse of DAAs will not dampen or damage elimination efforts, as some might fear, but rather it will legitimate the concerns of people who inject, decrease their suspicion of medical interventions, and better support the uptake of DAA treatments.

Abstract
BACKGROUND Direct-acting antiviral (DAA) treatment for hepatitis C virus (HCV) has been shown to be effective among PWID, but more real-world data on treatment outcomes is needed. The aim of this analysis was to assess the efficacy of DAA therapy, and the rate of reinfection and mortality among people attending an inner-city community health centre in Victoria, Canada. METHODS In this retrospective study, patients treated with DAA therapy between November 2014 and Dec 31, 2017 were included. Retrospective chart review was performed to assess recent injecting drug use (IDU, previous six months) or receipt of opioid agonist treatment (OAT). The primary endpoint was Sustained Virologic Response (SVR12). Secondary endpoints included HCV reinfection and mortality. RESULTS Of 270 patients who initiated DAA treatment (31% female), 20% (n=54) had HIV/HCV coinfection, 32% (n=84) had cirrhosis, 67% (n=181) had genotype 1, 6% (n=15) had genotype 2, 26% (n=69) had genotype 3. 46% (n=125) of patients were receiving OAT and 49% (n=132) reported recent IDU. 98% (n=265) completed treatment; two people stopped due to mental health, two people died, and one was non-adherent. 92% (249 of 270) achieved SVR12. 16 patients with End of Treatment (EOT) response did not have a SVR12; 7 were lost to follow-up; 2 people refused bloodwork; 2 people died; 1 had reinfection; and 4 had viral relapse. There was no difference in SVR12 by OAT (OAT, 93% vs. no OAT, 91%, P=0.435), recent injecting drug use (yes, 92% vs. no, 92%, P=0.904), or HIV status (HIV, 92% vs. no HIV, 94%, P=0.498). Eight cases of HCV reinfection were observed over 253 person-years of follow up (3.2 cases per 100 person-years; 95% CI 1.6-6.3). Twenty people died (6.3 per 100 person-years; 95% CI 3.9-10.3), including two during therapy (drug overdose, n=2) and 18 following therapy completion (drug overdose, n=7). CONCLUSION This study demonstrates that DAA treatment is effective among a marginalized population receiving care in an inner-city community health centre. The high mortality in this study highlights the importance of integrating HCV care within a framework addressing drug-related harms, preventing overdose mortality, addressing social inequalities, and improving the health of PWID.

Abstract
AIMS The advent of direct-acting antivirals for hepatitis C virus (HCV) and limited effectiveness of prevention have generated interest in "Treatment as Prevention" (TasP), in which those most likely to transmit HCV (i.e. people who inject drugs [PWID]) are treated to reduced secondary transmission. However, there are scant data regarding the feasibility of treating PWID at high risk for secondary transmission or the optimal approach to treatment delivery. METHODS We conducted a 2:1 randomized trial of modified directly-observed (mDOT) versus unobserved HCV treatment with ledipasvir-sofosbuvir daily for 8 weeks among PWID with 36 weeks of follow-up in San Francisco from 2015-2017. We evaluated recruitment-enrollment, treatment completion, end-of-treatment and 12-week response, and reinfection rate. RESULTS Of 83 individuals eligible for screening, 72 (87.6%) attended the screening visit, 33 were eligible, and 31 enrolled; mean age was 42 years, 81% were male, 74% white. All but one participant (in the mDOT arm) completed treatment and 89.4% of mDOT and 96.6% of unobserved arm visits were attended. HCV was undetectable for 96.8% (30/31) at end of treatment and 89.7% (26/29) 12 weeks later (1 relapse, 1 reinfection), with no differences by arm. Two additional reinfections were subsequently identified, for a reinfection rate of 16.3 (95% CI 5.3-50.5) per 100 person-years of observation. CONCLUSIONS It was feasible to recruit active PWID for HCV treatment and achieve high retention, viral response, and satisfaction with either mDOT or unobserved protocols, supporting treatment of PWID at risk of transmitting HCV to others. The reinfection rate suggests we successfully reached a high-risk population and that successful HCV TasP initiatives may aim to be sufficient in scope to significantly lower prevalence in the community.

Abstract
BACKGROUND Many people who inject drugs (PWID) are denied treatment for hepatitis C virus (HCV) infection, even if they are receiving opioid agonist therapy (OAT). Research suggests that HCV in PWID may be treated effectively, but optimal models of care for promoting adherence and sustained virologic response (SVR) have not been evaluated in the direct-acting antiviral (DAA) era. OBJECTIVE To determine whether directly observed therapy (DOT) and group treatment (GT) are more effective than self-administered individual treatment (SIT) in promoting adherence and achieving SVR among PWID receiving OAT. DESIGN Three-group, randomized controlled trial conducted from October 2013 to April 2017. (ClinicalTrials.gov: NCT01857245). SETTING Three OAT programs in Bronx, New York. PARTICIPANTS Persons aged 18 years and older with genotype 1 HCV infection who were willing to receive HCV therapy on site in the OAT program. Of 190 persons screened, 158 were randomly assigned to a study group and 150 initiated treatment: DOT (n = 51), GT (n = 48), and SIT (n = 51). INTERVENTION 2 intensive interventions (DOT and GT) and 1 control condition (SIT). MEASUREMENTS Primary: adherence, measured by using electronic blister packs. Secondary: HCV treatment completion and SVR 12 weeks after treatment completion. RESULTS Mean age was 51 years; 65% of participants had positive results on urine drug testing during the 6 months before treatment, and 75% reported ever injecting drugs. Overall adherence, estimated from mixed-effects models using the daily timeframe, was 78% (95% CI, 75% to 81%) and was greater among participants randomly assigned to DOT (86% [CI, 80% to 92%]) than those assigned to SIT (75% [CI, 70% to 81%]; difference, 11% [CI, 5% to 18%]; Bonferroni-corrected P = 0.001). No significant difference in adherence was observed between participants randomly assigned to GT (80% [CI, 74% to 86%]) and those assigned to SIT (difference, 4.7% [CI, -2% to 11%]; Bonferroni-corrected P = 0.29). The HCV treatment completion rate was 97%, with no differences among groups (P = 0.53). Overall SVR was 94% (CI, 89% to 97%); the SVR rate was 98% in the DOT group, 94% in the GT group, and 90% in the SIT group (P = 0.152). LIMITATION These findings may not be generalizable to PWID not enrolled in OAT programs. CONCLUSION All models of onsite HCV care delivered to PWID in OAT programs resulted in high SVR, despite ongoing drug use. Directly observed therapy was associated with greater adherence than SIT.

Abstract
Background Treatments for Hepatitis C virus (HCV) infection have vastly improved over the past few decades with current regimens now offering pangenotypic activity with excellent cure rates reported in clinical trials, including in the HIV-HCV coinfected population. However, there is some concern that stringent inclusion and exclusion criteria in the trials may lead to results that are not achievable in real-world populations. Methods Our study evaluated a real-world HIV-HCV coinfected population and compared them to the eligibility criteria for trials of two of the most recent approved HCV agents; sofosbuvir/velpatasvir and glecaprevir/pibrentasvir. Results Our study included 219 HIV-HCV coinfected patients and found that 89% met exclusion criteria for the sofosbuvir/velpatasvir trial and 90% met exclusion criteria for the glecaprevir/pibrentasvir trial. The majority of patients met more than one exclusion criteria with the most frequent criteria for exclusion being a non-approved ART regimen (58 and 47% respectively), having a psychiatric disorder (52%), active alcohol or injection drug use (27%), having an HIV viral load > 50 copies/ml (15%), a CrCl < 60 ml/min (13%) and a history of decompensated cirrhosis (13%). Conclusion Although the newer Hepatitis C treatments are very effective, the real world HIV-HCV coinfected population often have comorbidities and other characteristics that make them ineligible for clinical trials, such that they are barriers to treatment. These barriers need to be recognized and addressed in order to optimize treatment outcomes in the HIV patient population.

Abstract
Background: Limited data exist evaluating the treatment outcomes with direct-acting antivirals (DAAs) in patients with drug use in the community setting. We aim to assess the treatment response of DAAs in this subset of patients with or without the opioid agonist therapy (OAT). Methods: All the hepatitis C virus (HCV) infected patients treated with DAAs were retrospectively analyzed. Patients were stratified into two groups by the presence or absence of abusing alcohol, cocaine and heroin. All the patients who were assigned to the abuser group had positive urine toxicology with one of the drugs during the DAA treatment. The primary assessment was the sustained virologic response (SVR12) at 12 weeks post-treatment (SVR12). Results: Among the 314 patients, 152, 128 and 58 were patients with drug use, non-drug use and receiving OAT. Among the patients with injectable or non-injectable drug use treatment, completion rate was 99% (151/152) and SVR12 was 93.4%. Among the patients with no drug use treatment, completion rate was 95% (122/128) and SVR12 was 88.3%. Among patients receiving OAT alone, SVR12 was 100%, and in patients with OAT + other drug use, SVR12 was 96.5%. None of the patients included in this study discontinued the treatment due to adverse events associated with treatment medications. Conclusions: In this community-based study, DAAs are safe, effective with high overall SVR12 in patients with active drug use (injectable and non-injectable) and OAT enrolled patients. These results support the removal of drug use as a barrier to DAA therapy.

Effectiveness of Ledipasvir/Sofosbuvir and Sofosbuvir/Velpatasvir in People Who Inject Drugs and/or Those in Opioid Agonist Therapy. Hepatol Commun 2019; 3:478-492. [PMID: 30976739 PMCID: PMC6442698 DOI: 10.1002/hep4.1307] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2018] [Accepted: 12/14/2018] [Indexed: 12/12/2022] Open
Abstract
We evaluated the effectiveness of ledipasvir/sofosbuvir (LDV/SOF) in treating hepatitis C virus (HCV) genotype 1 and SOF/velpatasvir (SOF/VEL) for all genotypes among people who inject drugs (PWID) and those not injecting drugs and who were on or off opioid agonist therapy (OAT). Study participants comprised a population-based cohort in British Columbia, Canada. The British Columbia Hepatitis Testers Cohort includes data on individuals tested for HCV from 1990 to 2016 that are integrated with medical visits, hospitalization, and prescription drug data. We classified study participants as off OAT/recent injection drug use (off-OAT/RIDU), off OAT/past IDU (off-OAT/PIDU), off OAT/no IDU (off-OAT/NIDU), on OAT/IDU (on-OAT/IDU), and on OAT/no IDU (on-OAT/NIDU). We assessed sustained virologic response (SVR) 10 weeks after HCV treatment among study groups treated with LDV/SOF or SOF/VEL until January 13, 2018. Analysis included 5,283 eligible participants: 390 off-OAT/RIDU, 598 off-OAT/PIDU, 3,515 off-OAT/NIDU, 609 on-OAT/IDU, and 171 on-OAT/NIDU. The majority were male patients (64%-74%) and aged ≥50 years (58%-85%). The SVRs for off-OAT/RIDU, off-OAT/PIDU, off-OAT/NIDU, on-OAT/IDU, and on-OAT/NIDU were 91% (355/390), 95% (570/598), 96% (3,360/3,515), 93% (567/609), and 95% (163/171), respectively. Among those with no SVR, 14 individuals died while on treatment or before SVR assessment, including 4 from illicit drug overdose. In the overall multivariable model, off-OAT/RIDU, on-OAT/IDU, male sex, cirrhosis, treatment duration <8 weeks, treatment duration 8 weeks, and treatment with SOF/VEL were associated with not achieving SVR. Conclusion: In this large real-world cohort, PWID and/or those on OAT achieved high SVRs, although slightly lower than people not injecting drugs. This finding also highlights the need for additional measures to prevent loss to follow-up and overdose-related deaths among PWID.

Effectiveness of Direct-Acting Antiviral Therapy in Patients With Human Immunodeficiency Virus-Hepatitis C Virus Coinfection in Routine Clinical Care: A Multicenter Study. Open Forum Infect Dis 2019; 6:ofz100. [PMID: 30949539 PMCID: PMC6441587 DOI: 10.1093/ofid/ofz100] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2018] [Accepted: 02/25/2019] [Indexed: 02/06/2023] Open
Abstract
Background Direct-acting antiviral (DAA) therapy have been shown to be highly successful in clinical trials and observational studies, but less is known about treatment success in patients with a high burden of comorbid conditions, including mental health and substance use disorders. We evaluated DAA effectiveness across a broad spectrum of patients with human immunodeficiency virus (HIV)-hepatitis C virus (HCV) coinfection in routine clinical care, including those with psychosocial comorbid conditions. Methods The primary end point was sustained virologic response (SVR), defined as HCV RNA not detected or <25 IU/mL ≥10 weeks after treatment. We calculated SVR rates and 95% confidence intervals (CIs) in a modified intent-to-treat analysis. We repeated this analysis after multiply imputing missing SVR values. Results Among 642 DAA-treated patients, 536 had SVR assessments. The median age was 55 years; 79% were men, 59% black, and 32% white. Cirrhosis (fibrosis-4 index>3.25) was present in 24%, and 17% were interferon treatment experienced; 96% had genotype 1 infection and 432 (81%) had received ledipasvir-sofosbuvir. SVR occurred in 96.5% (95% CI, 94.5%-97.9%). Patients who were black, treatment experienced, or cirrhotic all had SVR rates >95%. Patients with depression and/or anxiety, psychotic disorder, illicit drug use, or alcohol use disorder also had high SVR rates, ranging from 95.4% to 96.8%. The only factor associated with lower SVR rate was early discontinuation (77.8%; 95% CI, 52.4%-93.6%). Similar results were seen in multiply imputed data sets. Conclusions Our study represents a large multicenter examination of DAA therapy in HIV/HCV-coinfected patients. The broad treatment success we observed across this diverse group of patients with significant comorbid conditions is highly affirming and argues for widespread implementation of DAA therapy.

Safety and efficacy of glecaprevir/pibrentasvir in patients with chronic hepatitis C genotypes 1-6 receiving opioid substitution therapy. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2019; 66:73-79. [PMID: 30735896 DOI: 10.1016/j.drugpo.2019.01.011] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2018] [Revised: 12/13/2018] [Accepted: 01/07/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND International guidelines recommend treatment of hepatitis C virus (HCV) infection in people who inject drugs (PWID), including those on opioid substitution therapy (OST). The pangenotypic combination of glecaprevir and pibrentasvir has shown high sustained virologic response at post-treatment Week 12 (SVR12) in clinical trials. Herein, we evaluate the safety and efficacy of glecaprevir/pibrentasvir in patients receiving OST. METHODS Pooled data from patients with HCV genotypes 1-6 who were treated with glecaprevir/pibrentasvir for 8, 12, or 16 weeks in eight Phase 2 and 3 trials were categorized by use of OST. Treatment completion, treatment adherence, SVR12, adverse events (AEs), and laboratory abnormalities were evaluated for patients receiving and not receiving OST. RESULTS Among 2256 patients, 157 (7%) were receiving OST. Compared with patients not receiving OST, OST patients were younger (mean age, 46.8 vs 52.8 years), male (69% vs 54%), white (93% vs 80%), HCV treatment-naïve (86% vs 72%), had HCV genotype 3 (60% vs 26%), and had a history of depression or bipolar disorder (43% vs 19%). Most patients completed (OST: 98% [n/N = 154/157]; non-OST: 99% [n/N = 2070/2099]) and were adherent (received ≥90% of study drug doses) to glecaprevir/pibrentasvir treatment (OST: 98% [n/N = 121/123]; non-OST: 99% [n/N = 1884/1905] among patients with available data). In the intention-to-treat population, SVR12 rates in OST and non-OST patients were 96.2% (n/N = 151/157; 95% CI 93.2-99.2) and 97.9% (n/N = 2055/2099; 95% CI 97.3-98.5), respectively. For OST patients, reasons for nonresponse included virologic relapse (<1%; n = 1), premature study drug discontinuation (<1%; n = 1), and loss to follow-up (3%; n = 4). AEs occurring in ≥10% of OST patients were headache, fatigue, and nausea. Drug-related serious AEs, AEs leading to study drug discontinuation, and Grade 3 or higher laboratory abnormalities were infrequent in both groups (<1%). No HCV reinfections occurred through post-treatment Week 12. CONCLUSION Glecaprevir/pibrentasvir is highly efficacious and well tolerated in HCV-infected patients receiving OST.

Abstract
Reinfection after direct-acting antiviral therapy may pose a challenge to hepatitis C virus elimination efforts. Reinfection risk is cited as a reason for not offering treatment to people who inject drugs. As treatment scale-up expands among populations with risks for reacquisition, acknowledgment that reinfection can and will occur is essential. Efforts to prevent and manage reinfection should be incorporated into individual- and population-level strategies. The risk of reinfection after successful treatment emphasises the need for education, harm reduction, and posttreatment surveillance. Reinfection must not be considered an impediment to treatment, if hepatitis C virus elimination is to be achieved.

Abstract
BACKGROUND Injection drug use is the primary mode of transmission for hepatitis C virus (HCV), and treatment guidelines recommend treating HCV-infected people who use drugs; however, concerns about adherence, effectiveness, and reinfection have impeded treatment uptake. METHODS Data were pooled from seven phase III trials that evaluated the efficacy and safety of 8 or 12 weeks of glecaprevir/pibrentasvir (G/P) in patients chronically infected with HCV genotypes 1-6. Patients had compensated liver disease, with or without cirrhosis, and were HCV treatment-naïve or -experienced with interferon or pegylated interferon ± ribavirin, or sofosbuvir plus ribavirin ± pegylated interferon. Patients were grouped into recent drug users (injection drug use ≤12 months before screening, positive urine drug screen [UDS], and/or drug-related adverse event), former drug users (>12 months before screening and negative UDS), or non-drug users. Assessments included sustained virologic response at 12 weeks posttreatment (SVR12), treatment adherence, and safety. RESULTS Among 1819 patients, 5%, 34%, and 61% were recent, former, and non-drug users, respectively. Treatment adherence and completion were high (≥96%) regardless of drug use status. SVR12 was achieved by 93% (n/N = 91/98), 97% (n/N = 591/610), and >99% (n/N = 1106/1111) of recent, former, and non-drug users, respectively (intention-to-treat analysis). The overall rates of virologic failure were ≤1.5% across all three subpopulations, with no HCV reinfections among recent drug users. Drug-related serious adverse events and adverse events leading to treatment discontinuation were experienced by ≤1% of patients. CONCLUSIONS G/P is a well-tolerated and efficacious pangenotypic regimen for chronic HCV-infected people with recent or active drug use.

Abstract
The burden of hepatitis C infection is considerable among people who inject drugs (PWID), with an estimated prevalence of 39%, representing an estimated 6.1 million people who have recently injected drugs living with hepatitis C infection. As such, PWID are a priority population for enhancing prevention, testing, linkage to care, treatment and follow-up care in order to meet World Health Organization (WHO) hepatitis C elimination goals by 2030. There are many barriers to enhancing hepatitis C prevention and care among PWID including poor global coverage of harm reduction services, restrictive drug policies and criminalization of drug use, poor access to health services, low hepatitis C testing, linkage to care and treatment, restrictions for accessing DAA therapy, and the lack of national strategies and government investment to support WHO elimination goals. On 5 September 2017, the International Network of Hepatitis in Substance Users (INHSU) held a roundtable panel of international experts to discuss remaining challenges and future priorities for action from a health systems perspective. The WHO health systems framework comprises six core components: service delivery, health workforce, health information systems, medical procurement, health systems financing, and leadership and governance. Communication has been proposed as a seventh key element which promotes the central role of affected community engagement. This review paper presents recommended strategies for eliminating hepatitis C as a major public health threat among PWID and outlines future priorities for action within a health systems framework.

Variation in hepatitis C virus treatment uptake between Canadian centres in the era of direct-acting antivirals. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2018; 65:41-49. [PMID: 30594080 DOI: 10.1016/j.drugpo.2018.08.012] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2018] [Revised: 08/07/2018] [Accepted: 08/14/2018] [Indexed: 12/25/2022]
Abstract
BACKGROUND Patients co-infected with HIV and hepatitis C virus (HCV) are a priority target for HCV treatment. The simplicity and efficacy of direct-acting antivirals (DAA) should help overcome patient, provider, and structural barriers to scaling up treatment. METHODS We estimated between-centre variation in DAA treatment uptake among 1734 patients enrolled at the 18 centres of the Canadian Co-Infection Cohort-a prospective cohort of adults co-infected with HIV and HCV. We then compared this variation to that observed during the interferon era. Time to treatment uptake was modeled using a Weibull time-to-event model adjusting for centre and patient characteristics thought to have an impact on treatment initiation in the DAA era. RESULTS At the time of administrative censoring (December 31, 2016), 981 cohort participants were eligible for second-generation DAA therapy (HCV RNA positive after November 21, 2013) of whom 278 initiated DAAs (16 patients per 100 person-years). Patients with low monthly income, Indigenous ethnicity, recent injection drug use, HCV genotype 3, or unknown HCV genotype were less likely to start treatment. After adjusting for patient characteristics, the estimated between-centre variance (σ2) was 0.29 (95% credible interval [CrI]: 0.09-0.89), considerably lower than during the interferon era (σ2 = 0.87, 95% CrI: 0.49-1.5). This between-centre variance was further reduced by the addition of centre-level effects for jurisdiction (σ2 = 0.15, 95% CrI: 0.02-0.60). CONCLUSION Much of the variation in treatment uptake between centres can now be attributed to regional differences. This suggests that after the introduction of DAAs, treatment barriers have shifted towards prescribing and reimbursement restrictions based on liver fibrosis, which vary by jurisdiction. The removal of these restrictions, however, will need to be paired with strategies to overcome patient-level barriers, which continue to prevent marginalized people and active substance users from accessing treatment.

Efficacy and Safety of Ombitasvir/Paritaprevir/Ritonavir and Dasabuvir With or Without Ribavirin in Patients With Chronic Hepatitis C Virus Genotype 1 Infection Receiving Opioid Substitution Therapy: A Post Hoc Analysis of 12 Clinical Trials. Open Forum Infect Dis 2018; 5:ofy248. [PMID: 30430131 PMCID: PMC6222025 DOI: 10.1093/ofid/ofy248] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2017] [Accepted: 09/25/2018] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND We evaluated the impact of opioid substitution therapy (OST) on the completion, adherence, efficacy, and safety of the 3-direct-acting antiviral regimen of ombitasvir, paritaprevir (identified by AbbVie and Enanta) co-dosed with ritonavir, and dasabuvir ± ribavirin among patients infected with hepatitis C virus (HCV) genotype (GT) 1, with or without compensated cirrhosis. METHODS Data were pooled from GT1-infected patients enrolled in 12 phase II/III/IIIb clinical trials and categorized by use of OST. Patients with ongoing drug use were excluded. HCV treatment completion, treatment adherence (≥90%), sustained virologic response at post-treatment week 12 (SVR12), and adverse events were assessed. RESULTS Of 4747 patients, 3% (n = 149) received OST. Among patients receiving OST vs those not receiving OST, 82% (n = 122) vs 52% (n = 2409) had GT1a infection; 76% (n = 113) vs 61% (n = 2792) were treatment naïve; and 17% (n = 25) vs 18% (n = 830) had cirrhosis, respectively. The proportion of patients completing HCV treatment did not differ between those receiving and not receiving OST (97% [n = 144] vs 98% [n = 4510], respectively), whereas adherence to treatment was reduced in patients receiving vs those not receiving OST (88% [n = 105] vs 97% [n = 4057], respectively). SVR12 was similar between patients receiving and not receiving OST (94% [n = 140] vs 96% [n = 4405], respectively; P = .273). Treatment was well tolerated. CONCLUSIONS Although treatment adherence was lower in patients receiving OST vs those not receiving OST, treatment completion and SVR12 were similar between groups. These data support the use of direct-acting antiviral therapies in patients receiving OST.

Direct acting antiviral-based treatment of hepatitis C virus infection among people who inject drugs in Georgia: A prospective cohort study. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2018; 62:104-111. [PMID: 30384026 DOI: 10.1016/j.drugpo.2018.07.016] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2018] [Revised: 07/28/2018] [Accepted: 07/28/2018] [Indexed: 12/15/2022]
Abstract
BACKGROUND People who inject drugs (PWID) are often excluded from HCV treatment programs due to concerns about their ability to adhere to care. Georgia has a high prevalence of HCV infection (5.4% of chronic cases in general population) with an epidemic concentrated among PWID. We evaluated adherence to care and sustained virologic response (SVR) among PWID in Georgia. METHODS In this observational study, participants with recent injecting drug use (previous 6 months) and chronic HCV attending a needle- and syringe-program were included. Participants received sofosbuvir and ribavirin +/- pegylated interferon, with peer-based support during treatment. The primary endpoint was undetectable HCV RNA 12 weeks post-treatment (SVR12). Factors associated with SVR were assessed using logistic regression. RESULTS Among 244 participants [HCV genotype (GT) 3, 52%; GT2, 25%; GT1, 19%; mixed GT, 4%]; 55% had cirrhosis. Overall, 24% were receiving OST and 50% injected drugs in the previous month. 98% (239 of 244) completed treatment, with 88% (210 of 239) having never delayed a medical appointment and 79% (189 of 239) never missing a dose of medication. Overall, SVR was 84.8% (207 of 244). SVR was 88.5% (207 of 234) among participants who attended 12-week follow up appointment for HCV RNA testing. In multivariate analyses, SVR was significantly associated with adherence (no missed doses) to treatment [vs. missed doses; adjusted OR (aOR) 2.77; 95% confidence interval (95%CI), 1.01-7.51), and genotype (vs. GT1; GT2, aOR 0.27; 95%CI 0.06-1.21; GT3, aOR 1.09; 95%CI 0.27-4.50; and mixed GT, aOR 0.14; 95%CI 0.02-0.97). CONCLUSION In this real-life study in a middle-income country, PWID treated for HCV and receiving a simple peer-support intervention demonstrated an excellent treatment response and good adherence, not associated with injecting drug use during treatment and OST at treatment initiation.

Adherence to sofosbuvir and velpatasvir among people with chronic HCV infection and recent injection drug use: The SIMPLIFY study. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2018; 62:14-23. [PMID: 30352330 DOI: 10.1016/j.drugpo.2018.08.013] [Citation(s) in RCA: 54] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2018] [Revised: 08/10/2018] [Accepted: 08/10/2018] [Indexed: 12/18/2022]
Abstract
BACKGROUND This study investigated treatment adherence among people with recent injecting drug use in a study of sofosbuvir/velpatasvir therapy for HCV infection. METHODS SIMPLIFY is an international open-label, single-arm multicentre study that recruited participants with recent injecting drug use (previous six months) and chronic HCV genotype (G) 1-6 infection between March and October 2016 in seven countries (19 sites). Participants received sofosbuvir/velpatasvir once-daily for 12 weeks administered in a one-week electronic blister pack (records the time and date of each dose) for 12 weeks. We evaluated non-adherence (<90% adherent) as measured by electronic blister-pack assessed using logistic regression and generalised estimating equations (continuous) with detailed analyses of dosing dynamics. RESULTS Among 103 participants, 97% (n = 100) completed treatment. Median adherence to therapy was 94%. Overall, 32% (n = 33) were considered non-adherent (<90% adherence). Adherence significantly decreased over the course of therapy. Recent stimulant injecting (cocaine and/or amphetamines) at treatment initiation and during treatment was independently associated with non-adherence. Inconsistent dose timing (standard deviation of daily dose timing of ≥240 min) was also independently associated with non-adherence to therapy. Factors associated with inconsistent dose timing included lower levels of education and recent stimulant injecting. SVR was similar among adherent and non-adherent populations (94% vs. 94%, P = 0.944). CONCLUSION This study demonstrated high adherence to once-daily sofosbuvir/velpatasvir therapy among a population of people with recent injecting drug use. Recent stimulant injecting prior to and during DAA therapy and inconsistent dose-timing during treatment was associated with non-adherence. However, there was no impact of non-adherence on response to therapy, suggesting that adherence is not a significant barrier to successful DAA therapy in people with recent injecting drug use.

Abstract
BACKGROUND There are concerns around poorer response to direct-acting antiviral (DAA) therapy for hepatitis C virus infection among people who use drugs. This systematic review assessed DAA treatment outcomes among people with recent drug use and those receiving opioid substitution therapy. METHODS Bibliographic databases and conference presentations were searched for observational studies and clinical trials assessing DAA treatment completion, sustained virological response (SVR), and loss to follow-up among people with recent drug use (injecting or non-injecting) and those receiving opioid substitution therapy. Meta-analysis was used to pool estimates and meta-regression to explore heterogeneity. FINDINGS 38 eligible studies, with 3634 participants, were included. The definition of recent drug use varied across studies, with drug use in the past 6 months and at the initiation of or during DAA therapy most commonly used. Among individuals with recent injecting or non-injecting drug use (21 studies; 1408 participants), treatment completion was 97·5% (95% CI 96·6-98·3) and SVR was 87·7% (95% CI 84·2-91·3). Among individuals receiving opioid substitution therapy (36 studies; 2987 participants), treatment completion was 97·4% (95% CI 96·5-98·3) and SVR was 90·7% (95% CI 88·5-93·0). Among individuals with recent injecting drug use (eight studies; 670 participants), treatment completion was 96·9% (95% CI 95·6-98·2) and SVR was 87·4% (95% CI 82·0-92·8). In meta-regression analysis, clinical trials (vs observational studies; adjusted odd ratio 2·18, 95% CI 1·27-3·75; p=0·006) and higher mean or median age (1·07, 1·02-1·12; p=0·008) were significantly associated with higher SVR. Clinical trials (0·45, 0·22-0·94; p=0·033) and older age (0·94, 0·88-0·99; p=0·034) were also significantly associated with a lower proportion of participants lost to follow-up. INTERPRETATION Response to DAA therapy was favourable among people with recent drug use (including those who inject) and those receiving opioid substitution therapy, supporting broadening access in these populations.

Evaluation of pharmaceutical intervention in direct-acting antiviral agents for hepatitis C virus infected patients in an ambulatory setting: a retrospective analysis. J Pharm Health Care Sci 2018; 4:17. [PMID: 30026959 PMCID: PMC6048910 DOI: 10.1186/s40780-018-0113-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2018] [Accepted: 06/06/2018] [Indexed: 01/17/2023] Open
Abstract
Background Direct-acting antivirals (DAAs) are known to improve tolerability and have higher efficacy and shorter treatment durations compared with conventional interferon (IFN)-based treatments for hepatitis C virus (HCV) infection. Management of drug interactions and maintenance of patient adherence are important to achieve adequate therapeutic effects, sustained virological response (SVR). In order to maximize the benefits of oral DAA therapy, we established an ambulatory care pharmacy practice, a model of integrated collaboration between physicians and pharmacists, for patients receiving IFN-free DAA therapy. In this study, we evaluated pharmaceutical intervention for patients visiting the ambulatory care pharmacy practice. Methods HCV-infected outpatients who visited our ambulatory care pharmacy practice between September 2014 and May 2017 were eligible for inclusion in the study. When IFN-free DAAs were first prescribed, the physicians recommended all patients to visit the ambulatory care pharmacy practice after their clinical examination. Subsequently, at the second visit or later, the patients visited the pharmacy service before the physician's examination. The primary endpoint was SVR, defined as HCV RNA below the lower limit of quantification after the completion of treatment. We also evaluated the adherence rate to DAAs, suggestions to the physicians by the pharmacists, and questions from the patients. All data were obtained retrospectively using an electronic medical record system. Results Among the 401 study subjects, 386 patients completed the IFN-free DAA therapy. A total of 365 patients have reached 12 or 24 weeks after completing the treatment. The overall SVR rate was 98.1% (358/365). The proportion of patients with adherence ≥90% was 99.3% (398/401). Two-hundred and sixty-seven (84%) among 318 suggestions of prescription made by the pharmacists mainly to manage the adverse events were accepted by the physicians. The pharmacists received and answered 1072 questions on DAA therapy from the patients. Conclusions This study indicates that the pharmaceutical intervention may contribute to enhanced adherence to DAAs and higher SVR rates in comparison with previous reports. This study also demonstrates that collaboration between physicians and pharmacists in an ambulatory setting provides favorable outcomes for patients receiving IFN-free DAAs.
