Restrictions for reimbursement of interferon-free direct-acting antiviral drugs for HCV infection in Europe

Viral Hepatitis C: From Unraveling the Nature of Disease to Cure and Global Elimination

BACKGROUND

The discovery of the hepatitis C virus (HCV) and direct-acting antiviral (DAA) drugs is one of the major milestones in the last 3 decades of medicine. These discoveries encouraged the World Health Organization (WHO) to set an ambitious goal to eliminate HCV by 2030, meaning "a 90% reduction in new cases of chronic HCV, a 65% reduction in HCV deaths, and treatment of 80% of eligible people with HCV infections."

SUMMARY

This review summarizes the key achievements from the discovery of HCV to the development of effective treatment and global elimination strategies. A better understanding of HCV structure, enzymes, and lifecycle led to the introduction of new drug targets and the discovery of DAA. Massive public health interventions are required, such as screening, access to care, treatment, and post-care follow-up, to make the most of DAA's potential. Screening must be supported by fast, accessible, sensitive, specific HCV diagnostic tests and noninvasive methods to determine the stage of liver disease. Linkage to care and treatment access are critical components of a comprehensive HCV elimination program, and decentralization plays a key role in ensuring their effectiveness.

KEY MESSAGES

Effective and simple screening strategies, rapid diagnostic tools, linkage to health care, and accessible treatment are key elements to achieving the WHO's goal. Incorporating treatment as prevention strategies into elimination programs together with preventive education and harm reduction interventions can have a profound and lasting impact on reducing both the incidence and prevalence of HCV. However, WHO's goal can be challenging to implement because of the need for high financial resources and strong political commitment.

Hepatitis C virus reinfection incidence among gay and bisexual men with HIV in Australia from 2016 to 2020

BACKGROUND

There is some concern that hepatitis C virus (HCV) reinfection might impact HCV micro-elimination efforts among gay and bisexual men (GBM) with HIV. However, there is a limited understanding of reinfection incidence in the context of unrestricted government-funded HCV treatment. We aimed to estimate HCV reinfection incidence among GBM with HIV in Australia from 2016 to 2020.

METHODS

Data were from 39 clinics participating in ACCESS, a sentinel surveillance network for blood borne viruses and sexually transmissible infections across Australia. GBM with HIV who had evidence of treatment or spontaneous clearance with at least one positive HCV RNA test, a subsequent negative HCV RNA test, and at least one additional HCV RNA test between 1st January 2016 and 31st December 2020 were eligible for inclusion. A new HCV RNA positive test and/or detectable viral load was defined as a reinfection. Generalised linear modelling was used to examine trends in reinfection.

RESULTS

Among 12 213 GBM with HIV who had at least one HCV test, 540 were included in the reinfection incidence analysis, of whom 38 (7%) had evidence of reinfection during the observation period. Over 1124 person-years of follow-up, the overall rate of reinfection was 3.4/100PY (95% CI 2.5-4.6). HCV reinfection incidence declined on average 30% per calendar year (Incidence Rate Ratio 0.70, 95% CI 0.54-0.91).

CONCLUSION

HCV reinfection incidence has declined among GBM with HIV in Australia since government-funded unrestricted DAAs were made available. Ongoing HCV RNA testing following cure and prompt treatment for anyone newly diagnosed is warranted to sustain this.

Direct-acting antiviral therapies for hepatitis C infection: global registration, reimbursement, and restrictions

Direct-acting antivirals (DAAs) for hepatitis C virus (HCV) infection have delivered high response rates (>95%) and simplified the management of HCV treatment, permitting non-specialists to manage patients without advanced liver disease. We collected and reviewed global data on the registration and reimbursement (government subsidised) of HCV therapies, including restrictions on reimbursement. Primary data collection occurred between Nov 15, 2021, and July 24, 2023, through the assistance of a global network of 166 HCV experts. We retrieved data for 160 (77%) of 209 countries and juristrictions. By mid-2023, 145 (91%) countries had registered at least one of the following DAA therapies: sofosbuvir-velpatasvir, sofosbuvir-velpatasvir-voxilaprevir, glecaprevir-pibrentasvir, sofosbuvir-daclatasvir, or sofosbuvir. 109 (68%) countries reimbursed at least one DAA therapy. Among 102 low-income and middle-income countries (LMICs), 89 (87%) had registered at least one HCV DAA therapy and 53 (52%) reimbursed at least one DAA therapy. Among all countries with DAA therapy reimbursement (n=109), 66 (61%) required specialist prescribing, eight (7%) had retreatment restrictions, seven (6%) had an illicit drug use restriction, five (5%) had an alcohol use restriction, and three (3%) had liver disease restrictions. Global access to DAA reimbursement remains uneven, with LMICs having comparatively low reimbursement compared with high-income countries. To meet WHO goals for HCV elimination, efforts should be made to assist countries, particularly LMICs, to increase access to DAA reimbursement and remove reimbursement restrictions-especially prescriber-type restrictions-to ensure universal access.

Long-term trends in hepatitis C prevalence, treatment uptake and liver-related events in the Swiss HIV Cohort Study

BACKGROUND AND AIMS

Treatment for chronic hepatitis C virus (HCV) infections changed dramatically in the last decade. We assessed changes in the prevalence of replicating HCV infection, treatment uptake and liver-related morbidity and mortality in persons with HIV (PWH) and hepatitis C in the Swiss HIV cohort study.

METHODS

We included all cohort participants between 2002 and 2021. We assessed yearly prevalence of replicating HCV infection, overall and liver-related mortality, as well as the yearly incidence of liver-related events in persons with at least one documented positive HCV-RNA.

RESULTS

Of 14 652 participants under follow-up, 2294 had at least one positive HCV-RNA measurement. Of those, 1316 (57%) ever received an HCV treatment. Treatment uptake increased from 8.1% in 2002 to a maximum of 32.6% in 2016. Overall, prevalence of replicating HCV infection declined from 16.5% in 2004 to 1.3% in 2021. HCV prevalence declined from 63.2% to 7.1% in persons who inject drugs, and from 4.1% to 0.6% in men who have sex with men. Among the 2294 persons with replicating HCV infection, overall mortality declined from a maximum of 3.3 per 100 patient-years (PY) to 1.1 per 100 PY, and incidence of liver-related events decreased from 1.4/100 PY to 0.2/100 PY.

CONCLUSIONS

The introduction of DAA therapy was associated with a more than 10-fold reduction in prevalence of replicating HCV infection in PWH, approaching the estimates in the general population. Overall mortality and liver-related events declined substantially in persons living with HIV and hepatitis C.

Prevalence of chronic HCV infection in EU/EEA countries in 2019 using multiparameter evidence synthesis

Background

Epidemiological data are crucial to monitoring progress towards the 2030 Hepatitis C Virus (HCV) elimination targets. Our aim was to estimate the prevalence of chronic HCV infection (cHCV) in the European Union (EU)/European Economic Area (EEA) countries in 2019.

Methods

Multi-parameter evidence synthesis (MPES) was used to produce national estimates of cHCV defined as: π = πrecρrec + πexρex + πnonρnon; πrec, πex, and πnon represent cHCV prevalence among recent people who inject drugs (PWID), ex-PWID, and non-PWID, respectively, while ρrec, ρex, and ρnon represent the proportions of these groups in the population. Information sources included the European Centre for Disease Prevention and Control (ECDC) national operational contact points (NCPs) and prevalence database, the European Monitoring Centre for Drugs and Drug Addiction databases, and the published literature.

Findings

The cHCV prevalence in 29 of 30 EU/EEA countries in 2019 was 0.50% [95% Credible Interval (CrI): 0.46%, 0.55%]. The highest cHCV prevalence was observed in the eastern EU/EEA (0.88%; 95% CrI: 0.81%, 0.94%). At least 35.76% (95% CrI: 33.07%, 38.60%) of the overall cHCV prevalence in EU/EEA countries was associated with injecting drugs.

Interpretation

Using MPES and collaborating with ECDC NCPs, we estimated the prevalence of cHCV in the EU/EEA to be low. Some areas experience higher cHCV prevalence while a third of prevalent cHCV infections was attributed to PWID. Further efforts are needed to scale up prevention measures and the diagnosis and treatment of infected individuals, especially in the east of the EU/EEA and among PWID.

Global, regional, and country-level coverage of testing and treatment for HIV and hepatitis C infection among people who inject drugs: a systematic review

BACKGROUND

People who inject drugs are disproportionately affected by HIV and hepatitis C virus (HCV) infections, while there is little global data on HIV and HCV testing and treatment coverage of this population. We conducted a systematic review to evaluate country-level, regional, and global coverage of HIV and HCV testing and treatment among people who inject drugs.

METHODS

We did a systematic review, and searched bibliographic databases (MEDLINE, Embase, and PsycINFO) and grey literature for studies published between Jan 1, 2017, and April 30, 2022, that evaluated the proportion of people who inject drugs who received testing or treatment for HIV or HCV. For each country, we estimated the proportion of people who inject drugs tested for HIV antibodies in the past 12 months (recent), people who inject drugs ever tested for HCV antibodies and HCV RNA, people who inject drugs with HIV currently receiving antiretroviral therapy, and people who inject drugs with HCV ever receiving HCV antiviral treatment. Regional and global estimates, weighted by the population size of people who inject drugs, were generated where sufficient data were available. This study is registered with PROSPERO (CRD42020173974).

FINDINGS

512 documents reported data eligible for analyses, including 337 peer-reviewed articles, 27 conference abstracts or presentations, and 148 documents from grey literature or supplementary searches. Data of recent HIV antibody testing were available for 67 countries and ever having had HCV antibody testing were available for 49 countries. Globally, an estimated 48·8% of people who inject drugs were recently tested for HIV antibodies (95% uncertainty interval [UI] 43·3-54·2%; range 0·9-86·0%), and 47·1% had ever been tested for HCV antibodies (95% UI 43·4-51·0%; range 0·0-93·3%). HCV RNA testing data were available from three countries. Coverage of HIV antibody testing was high (>75%) in four countries and for HCV antibody testing in 15 countries. The estimated uptake of current HIV treatment (18 countries) ranged from 2·6% to 81·9%, and the estimated uptake of ever having HCV treatment (23 countries) ranged from 1·8% to 88·6% across countries. Uptake of HIV treatment was high in two countries, and of HCV treatment in one country.

INTERPRETATION

HIV and HCV testing and treatment uptake among people who inject drugs was highly variable, and suboptimal in most countries. Strategies to improve access to HIV and HCV care among people who inject drugs and the availability of public health surveillance are urgently required.

Real-world hepatitis C treatment outcomes and reinfections among people who inject drugs at a needle and syringe program in Stockholm, Sweden

BACKGROUND

People who inject drugs (PWID) represent a population with an increased prevalence of hepatitis C (HCV) infections. HCV treatment among PWID is essential to reach the WHO goal of eliminating HCV as a major public health threat by 2030. Despite better understanding of PWID subgroups and changes in risk behaviors over time, more knowledge about HCV treatment outcomes in different HCV prevalence populations and settings is warranted to enhance the continuum of care.

METHODS

All Stockholm Needle and Syringe Program (NSP) participants who initiated HCV treatment between October 2017 and June 2020 were HCV RNA tested at end of treatment and twelve weeks thereafter to confirm cure with a sustained virological response (SVR). All cured participants were prospectively followed from SVR to the last negative HCV RNA test or a subsequent reinfection, until October 31, 2021.

RESULTS

Overall, 409 NSP participants initiated HCV treatment, 162 at the NSP and 247 in another treatment setting. There were a total of 6.4% treatment dropouts (n = 26), 11.7% among participants treated at the NSP and 2.8% among those treated elsewhere (p < 0.001). Stimulant use (p < 0.05) and not being in an opioid agonist treatment program (p < 0.05) was associated with dropout. More participants treated outside the NSP were lost to follow-up between end of treatment and SVR (p < 0.05). During follow-up post-SVR, 43 reinfections occurred, corresponding to a reinfection rate of 9.3/100 PY (95% CI 7.0, 12.3). Factors associated with reinfection were younger age (p < 0.001), treatment while in prison (p < 0.01) and homelessness (p < 0.05).

DISCUSSION

In this high HCV prevalence NSP setting, with a majority of stimulant users, treatment success was high and the level of reinfections manageable. To reach HCV elimination, there is a need to target specific PWID subgroups for HCV treatment, in both harm reduction and adjacent healthcare settings frequented by PWID.

Patient-Reported Outcomes During and After Hepatitis C Virus Direct-Acting Antiviral Treatment Among People Who Inject Drugs

OBJECTIVES

People who inject drugs (PWID) are at a high risk of hepatitis C virus (HCV) infection. HCV cure is associated with improved patient-reported outcomes (PROs), but there are little data among PWID. This study aimed to assess the change in PROs during and after HCV direct-acting antiviral (DAA) treatment.

METHODS

This analysis used data from 2 clinical trials of DAA treatment in PWID. PROs assessed included health-related quality of life, social functioning, psychological distress, housing, and employment. Generalized estimating equations and group-based trajectory modeling were used to assess changes in PROs over time.

RESULTS

No significant changes in the 3-level version of EQ-5D scores, EQ visual analogue scale scores, social functioning, psychological distress, and housing were observed over the 108-week study period. There was a significant increase in the proportion of participants employed (18% [95% confidence interval (CI) 12%-23%] at baseline to 28% [95% CI 19%-36%] at the end of the study). Participants were more likely to be employed at 24 weeks and 108 weeks after commencing treatment. Having stable housing increased the odds of being employed (odds ratio 1.70; 95% CI 1.00-2.90). The group-based trajectory modeling demonstrated that most outcomes remained stable during and after DAA treatment.

CONCLUSIONS

Although no significant improvement was identified in health-related quality of life after HCV DAA treatment, there was a modest but significant increase in employment during study follow-up. The study findings support the need for multifaceted models of HCV care for PWID addressing a range of issues beyond HCV treatment to improve quality of life.

Reducing barriers to the hepatitis C care cascade in prison via point-of-care RNA testing: a qualitative exploration of men in prison using an integrated framework

BACKGROUND AND AIMS

Hepatitis C virus (HCV) is highly prevalent within the prison setting. Although HCV testing and treatment are available within prisons, system barriers can impede progress along the HCV care cascade for those who are incarcerated. The PIVOT intervention used a 'one-stop-shop' model (i.e. point-of-care HCV RNA testing, Fibroscan-based liver disease assessment and treatment) at a reception prison in New South Wales, Australia. This analysis sought to understand the role of point-of-care HCV RNA testing at intake in reducing barriers to the HCV care cascade within the male prison setting.

DESIGN AND SETTING

Qualitative analysis using semi-structured interviews in a reception prison in Australia.

PARTICIPANTS

Twenty-four men enrolled in the PIVOT study; all participants had undergone HCV point-of-care testing in the intervention arm.

MEASUREMENTS

Høj's Integrated Framework informed this analysis.

FINDINGS

Participants widely expressed the view that point-of-care HCV RNA testing on entry was beneficial for care engagement. Point-of-care testing was perceived as timely (compared with standard pathology) and reduced opportunities for adjudication by correctional officers due to fewer clinic visits for testing and results. Adoption of routine opt-out testing at prison intake was regarded as an important strategy for normalising HCV testing (and likely to increase pathways to treatment uptake) and fostered patient candidacy (i.e. self-perceived eligibility to access care).

CONCLUSION

Twenty-four men in prison in New South Wales, Australia, who underwent opt-out point-of-care HCV RNA testing on entry into prison, widely supported the programme as a means of overcoming barriers to HCV testing and treatment in the prison setting, as well as providing public health benefits through early detection of HCV infection among people entering into custody.

Evolution of liver fibrosis after interferon-based anti-hepatitis C virus therapy failure in 3,049 chronic hepatitis C patients without cirrhosis

BACKGROUND AND STUDY AIMS

Liver fibrosis is the underlying causeof hepatitis C virus (HCV)-related disease progression to endpoints such as cirrhosis, liver failure, and hepatocellular carcinoma. The aim of our study was to assess changes in hepatic fibrosis in patients with chronic HCV who had a fibrosis evaluation at two time points at least six months apart.

PATIENTS AND METHODS

This was a retrospective cohort study that included patients who had failed interferon therapy and received HCV retreatment with direct-acting antivirals (DAAs) at least six months later. Patients were evaluated previously for fibrosis according to liver biopsy and fibrosis biomarkers were evaluated before pegylated interferon and ribavirin (PEG/RBV) therapy. Fibrosis was re-evaluated with fibrosis-4 (FIB-4) scores before starting DAAs.

RESULTS

A total of 3,049 patients were included [age 43.47 ± 9.07 years, 55.20 % males] and baseline histopathology showed F1, F2, and F3 in 16.86 %, 46.21 %, and 36.93 %, respectively. The mean time interval between the last dose of previously failed IFN-therapy to the first dose of DAAs was 2.38 (±1.07) years. Overall, there was a significant increase in FIB-4 scores at retreatment times (from 11.71 ± 1.13 to 22.26 ± 1.68, p < 0.001). Patients with baseline FIB-4 < 1.45 (n = 1,569) and between 1.45 and 3.25 (n = 1,237) had significant increases in their FIB-4 at the retreatment time point [median difference; 0.41 (0.91) and 0.24 (1.5), p < 0.001, respectively], whereas patients with FIB-4 > 3.25 had significant reduction of their FIB-4 score at a retreatment timepoint [-0.98 (2.93), p ≤ 0.001].

CONCLUSION

Fibrosis progressed in most patients, even within six months for some patients, and this indicates retreatment of non-system vascular resistance patients even if they do not have significant fibrosis.

Treatment as prevention effect of direct-acting antivirals on primary hepatitis C virus incidence: Findings from a multinational cohort between 2010 and 2019

BACKGROUND

Broad direct-acting antiviral (DAA) access may reduce hepatitis C virus (HCV) incidence through a "treatment as prevention" (TasP) effect. We assessed changes in primary HCV incidence following DAA access among people living with HIV (PLHIV).

METHODS

We used pooled individual-level data from six cohorts from the International Collaboration on Hepatitis C Elimination in HIV Cohorts (InCHEHC). Follow-up started from the first recorded negative HCV antibody test date and ended at last negative antibody test or estimated infection date. Follow-up was restricted to 2010-2019. We used segmented Poisson regression to model trends across pre-, limited- (i.e., restrictions on access) and broad-DAA access periods.

FINDINGS

Overall, 45,942 participants had at least one HCV antibody negative result and follow-up between 2010 and 2019. We observed 2042 incident HCV infections over 248,189 person-years (PY). Pooled incidence decreased from 0.91 per 100 PY in 2015 to 0.41 per 100 PY in 2019. Compared to the average pre-DAA period incidence (0.90 per 100 PY), average incidence was similar during the limited-DAA access period (Incidence rate ratio [IRR] = 0.98; 95%CI = 0.87, 1.11), and 52% lower during the broad-DAA access period (IRR = 0.48; 95%CI = 0.42, 0.52). The average annual decline in HCV incidence was 2% in the pre-DAA period; an additional 9% annual decline in incidence was observed during the limited-DAA access period (IRR = 0.91; 95%CI = 0.82, 1.00) and a further 20% decline in the broad-DAA access period (IRR = 0.80, 95%CI = 0.73, 0.89).

INTERPRETATION

Our findings suggest that broad DAA access has a TasP effect on primary HCV incidence among PLHIV. Based on the initial years of DAA availability, the countries in the InCHEHC collaboration are on track to meet the World Health Organization's 80% HCV incidence reduction target for PLHIV by 2030.

Interventions to enhance testing and linkage to treatment for hepatitis C infection for people who inject drugs: A systematic review and meta-analysis

BACKGROUND

With the advent of direct acting antiviral (DAA) therapies for the treatment of hepatitis C virus (HCV), the World Health Organization recommended a goal to eliminate HCV as a public health threat globally by 2030. With the majority of new and existing infections in high income countries occurring among people who inject drugs, achieving this goal will require the design and implementation of interventions which address the unique barriers to HCV care faced by this population.

METHODS

In this systematic review and meta-analysis, we searched bibliographic databases and conference abstracts to July 21, 2020 for studies assessing interventions to improve the following study outcomes: HCV antibody testing, HCV RNA testing, linkage to care, and treatment initiation. We included both randomised and non-randomised studies which included a comparator arm. We excluded studies which enrolled only paediatric populations (<18 years old) and studies where the intervention was conducted in a different healthcare setting than the control or comparator. This analysis was restricted to studies conducted among people who inject drugs. Data were extracted from the identified records and meta-analysis was used to pool the effect of interventions on study outcomes. This study was registered in PROSPERO (CRD42020178035).

FINDINGS

Of 15,342 unique records, 45 studies described the implementation of an intervention to improve HCV testing, linkage to care and treatment initiation among people who inject drugs. These included 27 randomised trials and 18 non-randomised studies with the risk of bias rated as "critical" for most non-randomised studies. Patient education and patient navigation to address patient-level barriers to HCV care were shown to improve antibody testing uptake and linkage to HCV care respectively although patient education did not improve antibody testing when restricted to randomised studies. Provider care coordination to address provider level barriers to HCV care was effective at improving antibody testing uptake. Three different interventions to address systems-level barriers to HCV care were effective across different stages of HCV care: point-of-care antibody testing (linkage to care); dried blood-spot testing (antibody testing uptake); and integrated care (linkage to care and treatment initiation).

INTERPRETATION

Multiple interventions are available that can address the barriers to HCV care for people who inject drugs at the patient-, provider-, and systems-level. The design of models of care to improve HCV testing and treatment among people who inject drugs must consider the unique barriers to care that this population faces. Further research, including high-quality randomised controlled trials, are needed to robustly assess the impact these interventions can have in varied populations and settings.

Perceptions of hepatitis C treatment and reinfection risk among HIV-positive men who have sex with men and engage in high risk behaviours for hepatitis C transmission: The CEASE qualitative study

BACKGROUND

Globally, treatment uptake for hepatitis C virus (HCV) infection among HIV-HCV coinfected men who have sex with men (MSM) has substantially increased since the advent of interferon-free direct-acting antivirals (DAA). However, HIV-positive MSM who engage in high risk behaviours are at an increased risk of HCV reinfection post-treatment. The aim of this study was to investigate perceptions of HCV diagnosis, treatment and reinfection risk among HCV-HIV coinfected MSM who engage in drug use and/or high risk sexual behavior in Sydney, Australia.

METHODS

Participants were recruited from the Control and Elimination within AuStralia of HEpatitis C from people living with HIV (CEASE) cohort (n=402) who reported engaging in drug use and/or high risk sexual behavior for transmission of HCV infection. Participants were interviewed about their perceptions of HCV diagnosis, treatment, and reinfection risk. Interview data were transcribed, coded, and analyzed thematically.

RESULTS

Of 33 participants interviewed (mean age 49 years), many participants were 'shocked' by their HCV diagnosis. Participants who believed they acquired HCV infection through sexual exposure felt it was important that their healthcare practitioner agreed with their perspective to mitigate stigmatizing experiences. Overall, participants expressed high satisfaction with their treatment experience due to long-standing therapeutic relationships with their HIV physician. Many participants expressed knowledge of how to prevent HCV reinfection from injection drug use, yet other than condom usage, most were unsure how to reduce high risk sexual activity with such discussions occurring less frequently with healthcare practitioners.

CONCLUSION

Findings indicate that MSM who engage in drug use and high risk sexual activity would benefit from additional education on reducing reinfection risk through sexual activity and services to reduce substance use, if requested.

Closing the hepatitis C treatment gap: United States strategies to improve retention in care

The hepatitis C virus (HCV) treatment landscape is shifting given the advent of direct-acting antivirals and a global call to action by the World Health Organization. Eliminating HCV is now an issue of healthcare delivery. Treatment is limited by the complexity of the HCV care continuum, expensive therapy and competing health burdens experienced by an underserved HCV population. The objective of this literature review was to assess strategies to improve retention in HCV care, with particular focus on those implemented in the United States. We identified barriers in HCV care retention and propose solutions to increase HCV treatment delivery. The following recommendations are herein described: improving the cohesion of health services through localized care and integrated case management, expanding the supply of non-specialist HCV treatment providers, leveraging patient navigators and care coordinators, improving adherence through directly observed therapy and reducing cost barriers through value-based payment and pharmaceutical subscription models.

The Payer License Agreement, or "Netflix model," for hepatitis C virus therapies enables universal treatment access, lowers costs and incentivizes innovation and competition

BACKGROUND AND AIMS

High unit prices of treatments limit access. For epidemics like that of hepatitis C virus (HCV), reduced treatment access increases prevalence and incidence, making the infectious disease increasingly difficult to manage. The objective of the current study was to construct and test an alternative pricing model, the Payer License Agreement (PLA), and determine whether it could improve outcomes, cut costs and incentivize innovation versus the current unit-based pricing model.

METHODS

We built and used computational models of hepatitis C disease progression, treatment, and pricing in historical and future scenarios and quantitatively analyzed their economic and epidemiological impact in three high-income countries.

RESULTS

This study had three key results regarding HCV treatment. First, if the PLA model had been implemented when interferon-free direct-acting antiviral (DAA) combinations launched, the number of patients treated and cured would have more than doubled in the first three years, while the liver-related deaths (LRDs) would have decreased by around 40%. Second, if the PLA model had been implemented beginning in 2018, the year that several Netflix-like payment models were under implementation, the number of treated and cured patients would nearly double, and the LRDs would decline by more than 55%. Third, implementing the PLA model would result in a decline in total payer costs of more than 25%, with an increase to pharmaceutical manufacturer revenues of 10%. These results were true across the three healthcare landscapes studied, the USA, the UK and Italy, and were robust against variations to critical model parameters through sensitivity analysis.

CONCLUSIONS AND RELEVANCE

These results suggest that implementation of the PLA model in high-income countries across a variety of health system contexts would improve patient outcomes at lower payer cost with more stable revenue for pharmaceutical manufacturers. Health policy-makers in high-income countries should consider the PLA model for application to more cost-effective management of HCV, and explore its application for other infectious diseases with curative therapies available now or soon.

Reaching people receiving opioid agonist therapy at community pharmacies with hepatitis C virus: an international randomised controlled trial

BACKGROUND

Conventional healthcare models struggle to engage those at risk of hepatitis C virus (HCV) infection. This international study evaluated point-of-care (PoC) HCV RNA diagnostic outreach and direct-acting antiviral (DAA) treatment for individuals receiving opioid agonist therapy (OAT) in community pharmacies.

AIMS

We assessed the effectiveness of a roving nurse-led pathway offering PoC HCV RNA testing to OAT clients in community pharmacies relative to conventional care.

METHODS

Pharmacies in Scotland, Wales, and Australia were randomised to provide PoC HCV RNA testing or conventional referral. Pharmacists directed OAT clients to on-site nurses (intervention) or local clinics (control). Infected participants were treated with DAAs, alongside OAT. Primary outcome was the number of participants with sustained virologic response at 12 weeks (SVR) and analysed using mixed effects logistic regression in the intention-to-treat (ITT) population.

RESULTS

Forty pharmacies were randomised. The ITT population contained 1410 OAT clients. In the conventional arm (n = 648), 62 (10%) agreed to testing, 17 (27%) were tested, 6 (35%) were positive and 5 (83%) initiated treatment. In the intervention arm (n = 762), 148 (19%) agreed to testing, 144 (97%) were tested, 23 (16%) were positive and 22 (96%) initiated treatment. SVR was obtained by 2 (40%; conventional) and 18 (82%; intervention). Intervention arm participants had higher odds of testing, OR 16.95 (7.07-40.64, p < 0.001); treatment, OR 4.29 (1.43-12.92, p = 0.010); and SVR, OR 8.64 (1.82-40.91, p = 0.007).

CONCLUSIONS

Nurse-led PoC diagnosis in pharmacies made HCV care more accessible for OAT clients relative to conventional care. However, strategies to improve testing uptake are required.

Treatment Candidacy for Pharmacologic Therapies for NASH

Nonalcoholic steatohepatitis (NASH) has emerged as one of the important causes of cirrhosis and hepatocellular carcinoma, and over 50 therapeutic agents are in various phases of clinical development. Recently, obeticholic acid has achieved the interim histological endpoint of fibrosis improvement with no worsening of NASH in the phase 3 REGENERATE study, and now patients are being followed for long-term clinical outcomes. Several drugs are in Phase 3 trials with a goal to achieve conditional registration under the subpart H pathway by the United States Food and Drug Administration (FDA). It is thus timely to consider the current situation and the way ahead in the management of NASH. In this article, we review the natural history of nonalcoholic fatty liver disease, upcoming treatments for NASH and various assessments. Based on the current knowledge, we discuss what should be the target treatment population and whether noninvasive tests are ready to guide NASH treatments both for patient selection and evaluation of treatment response.

Interventions to enhance testing, linkage to care, and treatment initiation for hepatitis C virus infection: a systematic review and meta-analysis

BACKGROUND

Despite the goal set by WHO to eliminate hepatitis C virus (HCV) as a public health threat, uptake of HCV testing and treatment remains low. To achieve this target, evidence-based interventions are needed to address the barriers to care for people with, or at risk of, HCV infection. We aimed to assess the efficacy of interventions to improve HCV antibody testing, HCV RNA testing, linkage to HCV care, and treatment initiation.

METHODS

In this systematic review and meta-analysis, we searched MEDLINE (PubMed), Scopus, Web of Science, the Cochrane Central Register of Controlled Trials, and PsycINFO without language restrictions for reports published between database inception and July 21, 2020, assessing the following primary outcomes: HCV antibody testing; HCV RNA testing; linkage to HCV care; and direct-acting antiviral treatment initiation. We also searched key conference abstracts. We included randomised and non-randomised studies assessing non-pharmaceutical interventions that included a comparator or control group. Studies were excluded if they enrolled only paediatric populations (aged <18 years) or if they conducted the intervention in a different health-care setting to that of the control or comparator. Authors were contacted to clarify study details and to obtain additional population-level data. Data were extracted from the records identified into a pre-piloted and standardised data extraction form and a random-effects meta-analysis was used to pool the effects of the interventions on study outcomes. This study is registered in PROSPERO, CRD42020178035.

FINDINGS

Of 15 342 unique records identified, 142 were included, which reported on 148 unique studies (47 randomised controlled trials and 101 non-randomised studies). Medical chart reminders, provider education, and point-of-care antibody testing significantly improved at least three study outcomes compared with a comparator or control. Interventions that simplified HCV testing, including dried blood spot testing, point-of-care antibody testing, reflex RNA testing, and opt-out screening, significantly improved testing outcomes compared with a comparator or control. Enhanced patient and provider support through patient education, provider care coordination, and provider education also significantly improved testing outcomes compared with a comparator or control. Integrated care and patient navigation or care coordination significantly improved linkage to care and the uptake of direct-acting antiviral treatment compared with a comparator or control.

INTERPRETATION

Several interventions to improve HCV care that address several key barriers to HCV care were identified. New models of HCV care must be designed and implemented to address the barriers faced by the population of interest. Further high-quality research, including rigorously designed randomised studies, is still needed in key populations.

HCV Elimination in Central Europe with Particular Emphasis on Microelimination in Prisons

In 2016, the WHO announced a plan to eliminate viral hepatitis as a public health threat by 2030. In this narrative review, experts from Bulgaria, Croatia, the Czech Republic, Hungary, Latvia, Lithuania, Poland and Slovakia assessed the feasibility of achieving the WHO 2030 target for HCV infections in Central Europe. They focused mainly on HCV micro-elimination in prisons, where the highest incidence of HCV infections is usually observed, and the impact of the COVID-19 pandemic on the detection and treatment of HCV infections. According to the presented estimates, almost 400,000 people remain infected with HCV in the analyzed countries. Interferon-free therapies are available ad libitum, but the number of patients treated annually in the last two years has halved compared to 2017–2019, mainly due to the COVID-19 pandemic. None of the countries analyzed had implemented a national HCV screening program or a prison screening program. The main reason is a lack of will at governmental and prison levels. None of the countries analyzed see any chance of meeting the WHO targets for removing viral hepatitis from the public threat list by 2030, unless barriers such as a lack of political will and a lack of screening programs are removed quickly.

'Not just one box that you tick off' - Deconstructing the hepatitis C care cascade in the interferon-free direct acting antiviral era from the client perspective

BACKGROUND

To achieve hepatitis C viral (HCV) elimination targets set by the World Health Organisation, pillars of the HCV care cascade are often referenced to track progress. The aim of this qualitative study was to explore the limitations of the care cascade framework through the real-world accounts of 'HCV journeys' among people who inject drugs (PWID), with particular attention to the intersection of PWID agency and structural determinants in the healthcare system.

METHODS

An in-depth analysis was conducted on five case studies to better understand participant experiences 'behind the cascade pillars'. The five case studies were drawn from the ETHOS Engage cohort as exemplars of the real-world complexities of people's HCV cascade journeys. Inclusion criteria for the qualitative study were participant has voluntarily signed the informed consent form, aged ≥18 years, HCV antibody positive by self-report, clients of selected sites participating in the ETHOS Engage cohort, and sufficiently proficient in English to participate in an interview. Thirty-four semi-structured interviews were conducted with participants who had received or had not received HCV treatment to identify barriers and facilitators to HCV care.

RESULTS

Participants 'housed' at the 'HCV RNA diagnosed pillar' (n = 2; Will; Julie) reported withholding their HCV serostatus in certain healthcare settings for fear that disclosure would lead to discriminatory decision-making from their treating physician. among participants who had completed treatment (n = 3; Corey; John; Nora) two reported still being unsure of their HCV status >6 months post-treatment. Ongoing feelings of frustration and shame were expressed in this 'post-cure care pillar' due to a perceived lack of quality care from clinic services and continued uneasiness when discussing drug use and reinfection while receiving opioid agonist treatment (OAT). Both case 'categories' described often tenuous therapeutic relationships with their physicians and recommended task-shifting to nurses and trusted case workers for ongoing care.

CONCLUSION

The care cascade provides a linear, two dimensional snapshot of clinical targets. Our findings illuminate structural barriers not visible behind its 'static' pillars, presenting insights into experiences among PWID otherwise dismissed as 'disengaged' or 'lost to follow-up'.

Monitoring progress towards elimination of hepatitis B and C in the EU/EEA

This paper presents data on selected indicators to show progress towards elimination goals and targets for hepatitis B and hepatitis C in the 31 countries of the European Union (EU) and European Economic Area (EEA). A monitoring system was developed by the European Centre for Disease Prevention and Control, which combined newly collected data from EU/EEA countries along with relevant data from existing sources. Data for 2017 were collected from the EU/EEA countries via an online survey. All countries provided responses. In 2017, most countries reporting data had not reached prevention targets for childhood hepatitis B vaccination and for harm reduction services targeting people who inject drugs (PWID). Four of 12 countries had met the target for proportion of people living with chronic HBV diagnosed and seven of 16 met this target for hepatitis C. Data on diagnosed cases treated were lacking for hepatitis B. Of 12 countries reporting treatment data for hepatitis B, only Iceland met the target. This first collection of data across the EU/EEA highlighted major issues with data completeness and quality and in the indicators that were used, which impairs a clear overview of progress towards the elimination of hepatitis. The available data, whilst incomplete, suggest that as of 2017, the majority of the EU/EEA countries were far from meeting most of the 2020 targets, in particular those relating to harm reduction and diagnosis. It is critical to improve the data collected in order to develop more effective services for hepatitis prevention, diagnosis, and treatment that are needed in order to meet the 2030 elimination targets.

Does Hepatitis C Virus Treatment by Directly Acting Antivirals Obligate Shifting Patients with Type 2 Diabetes from Oral Hypoglycemic Drugs to Insulin Therapy?

PURPOSE

The aim of the present work was to investigate whether hepatitis C virus treatment by directly acting antivirals obligate shifting patients with type 2 diabetes from oral hypoglycemic drugs to insulin therapy.

METHODS

This was a prospective study including 92 treatment-naïve patients with chronic hepatitis C virus infection and type 2 diabetes who were eligible for treatment with directly acting antivirals (sofosbuvir + daclatasvir ± ribavirin). Patients in the study were divided into two groups; group 1 included 22 patients on insulin therapy and group 2 included 70 patients on oral antidiabetic medications. Patients were advised to keep on their anti-diabetic treatment.

RESULTS

All our patients achieved sustained virologic response with significantly lower HbA_1c 12 weeks after the end of therapy (p. values 0.001 for group 1 and group 2). There was no statistically significant difference in HbA_1c level post-treatment between both groups (p. value 0.352).

CONCLUSION

Achievement of sustained virologic response using interferon free, directly acting antivirals-based regimen was associated with significantly lower HbA_1c 12 weeks after the end of therapy. The type of treatment used for type 2 diabetes (oral drugs or insulin) did not affect improved glycemic control observed after achieving sustained virologic response.

The European Prevalence of Resistance Associated Substitutions among Direct Acting Antiviral Failures

Background: Approximately 71 million people are still in need of direct-acting antiviral agents (DAAs). To achieve the World Health Organization Hepatitis C elimination goals, insight into the prevalence and influence of resistance associated substitutions (RAS) is of importance. Collaboration is key since DAA failure is rare and real-life data are scattered. We have established a European collaboration, HepCare, to perform in-depth analysis regarding RAS prevalence, patterns, and multiclass occurrence. Methods: Data were extracted from the HepCare cohort of patients who previously failed DAA therapy. Geno—and subtypes were provided by submitters and mostly based on in-house assays. They were reassessed using the Comet HCV subtyping tool. We considered RAS to be relevant if they were associated with DAA failure in vivo previously reported in literature. Results: We analyzed 938 patients who failed DAA therapy from ten different European countries. There were 239 genotypes (GT) 1a, 380 GT1b, 19 GT2c, 205 GT3a, 14 GT4a, and 68 GT4d infections. Several unusual subtypes (n = 15) (GT1b/g/l, GT3b, GT4k/n/r/t) were present. RAS appeared in over 80% of failures and over a quarter had three or more RAS. Multiclass RAS varied over target region and genotype between 0–48%. RAS patterns such as the Q30R + L31M and Q30R + Y93H in GT1a, the L31V + Y93H and L31V + Y93H for GT1b, and A30K + L31M and A30K/V + Y93H for GT3a all occurred with a prevalence below 5%. Conclusion: RAS occur frequently after DAA failures and follow a specific genotype and drug related pattern. Interpretation of the influence of RAS on retreatment is challenging due to various patterns, patients’ characteristics, and previous treatment history. Moving towards HCV elimination, an ongoing resistance surveillance is essential to track the presence of RAS, RAS patterns and gather data for a re-treatment algorithm.

Hepatitis C reinfection in former and active injecting drug users in Belgium

BACKGROUND

There is currently no systematic screening for hepatitis C (HCV) reinfection in people who inject drugs (PWID) after treatment in Belgium. However, in a recent meta-analysis, the overall HCV reinfection rate was 5.9/100 person-years (PY) among PWID. Accordingly, this study was undertaken to investigate the reinfection rate in former and active PWID who achieved the end of treatment response after direct-acting antiviral (DAA) treatment in Belgium.

METHODS

This observational cross-sectional study recruited individuals with a history of injecting drug use who had achieved the end of treatment response to any DAA treatment between 2015 and 2020. Participants were offered a post-treatment HCV RNA test.

RESULTS

Eighty-five potential participants were eligible to participate and contacted, of whom 60 participants were enrolled in the study with a median age of 51.0 (IQR 44.3-56.0) years; it was reported that 23.3% continued to inject drugs intravenously after DAA treatment. Liver cirrhosis was present in 12.9%. The majority had genotype 1a (51.7%) or genotype 3 (15.0%) infection. We detected no reinfections in this study population. The total time patients were followed up for reinfection in the study was 78.5 PY (median 1.0 years IQR 0.4-2.0).

CONCLUSION

Reinfection after successful treatment with DAA initially appears to be very low in Belgian PWID. Therefore, efforts should be made to screen individuals with persistent risk behaviors for reinfection systematically. In addition, a national HCV registry should be established to accurately define the burden of HCV infection and reinfection in Belgium and support the elimination of viral hepatitis C in Europe.

On-site testing and case management to improve hepatitis C care in drug users: a prospective, longitudinal, multicenter study in the DAA era

Background

Screening and treatment of hepatitis C virus (HCV) infection in people who use drugs (PWUD) remains insufficient. Reducing the burden of HCV infection in PWUD requires interventions focusing on the different steps of the HCV care cascade.

Methods

We performed a prospective, multicenter study, evaluating the impact of an HCV care model on the HCV care cascade among PWUD attending an addiction care center in Belgium between 2015 and 2018. Interventions within the care model consisted of pre-test counseling, on-site HCV screening and case management services. A multiple logistic regression model was performed to identify the independent factors influencing the outcomes.

Results

During the study period, 441 PWUD were registered at the addiction care center, 90% (395/441) were contacted, 88% (349/395) were screened for HCV infection. PWUD were more likely to be screened if they had ever injected drugs (p < .001; AOR 6.411 95% CI 3.464–11.864). In 45% (157/349), the HCV antibody (Ab) test was positive, and in 27% (94/349) HCV RNA was positive. Within the Belgian reimbursement criteria (fibrosis stage ≥ F2), 44% (41/94) were treated. Specialist evaluation at the hospital was lower for PWUD receiving decentralized opioid agonist therapy (p = .005; AOR 0.430 95% CI 0.005–0.380), PWUD with unstable housing in the past 6 months before inclusion (p = .015; AOR 0.035 95% CI 0.002–0.517) or if they were recently incarcerated (p = .001; AOR 0.010 95% CI 0.001–0.164).

Conclusions

This HCV care model demonstrated high screening, linkage to care, and treatment initiation among PWUD in Belgium. Using the cascade of care to guide interventions is easy and necessary to monitor results. This population needs guidance, not only for screening and treatment initiation but also for the long-term follow-up since one in six had cirrhosis and could develop hepatocellular carcinoma. Further interventions are necessary to increase linkage to care and treatment initiation. Universal access to direct-acting antiviral therapy from 2019 will contribute to achieving HCV elimination in the PWUD population.

Hepatitis C virus infection and risk of liver-related and non-liver-related deaths: a population-based cohort study in Naples, southern Italy

Background

Hepatitis C virus (HCV) infection represents a global health issue with severe implications on morbidity and mortality. This study aimed to evaluate the impact of HCV infection on all-cause, liver-related, and non-liver-related mortality in a population living in an area with a high prevalence of HCV infection before the advent of Direct-Acting Antiviral (DAA) therapies, and to identify factors associated with cause-specific mortality among HCV-infected individuals.

Methods

We conducted a cohort study on 4492 individuals enrolled between 2003 and 2006 in a population-based seroprevalence survey on viral hepatitis infections in the province of Naples, southern Italy. Study participants provided serum for antibodies to HCV (anti-HCV) and HCV RNA testing. Information on vital status to December 2017 and cause of death were retrieved through record-linkage with the mortality database. Hazard ratios (HRs) for cause-specific mortality and 95% confidence intervals (CIs) were estimated using Fine-Grey regression models.

Results

Out of 626 deceased people, 20 (3.2%) died from non-natural causes, 56 (8.9%) from liver-related conditions, 550 (87.9%) from non-liver-related causes. Anti-HCV positive people were at higher risk of death from all causes (HR = 1.38, 95% CI: 1.12–1.70) and liver-related causes (HR = 5.90, 95% CI: 3.00–11.59) than anti-HCV negative ones. Individuals with chronic HCV infection reported an elevated risk of death due to liver-related conditions (HR = 6.61, 95% CI: 3.29–13.27) and to any cause (HR = 1.51, 95% CI: 1.18–1.94). The death risk of anti-HCV seropositive people with negative HCV RNA was similar to that of anti-HCV seronegative ones. Among anti-HCV positive people, liver-related mortality was associated with a high FIB-4 index score (HR = 39.96, 95% CI: 4.73–337.54).

Conclusions

These findings show the detrimental impact of HCV infection on all-cause mortality and, particularly, liver-related mortality. This effect emerged among individuals with chronic infection while those with cleared infection had the same risk of uninfected ones. These results underline the need to identify through screening all people with chronic HCV infection notably in areas with a high prevalence of HCV infection, and promptly provide them with DAAs treatment to achieve progressive HCV elimination and reduce HCV-related mortality.

Opportunities to enhance linkage to hepatitis C care among hospitalised people with recent drug dependence in New South Wales, Australia: A population-based linkage study

BACKGROUND

People who inject drugs are at greater risk of hepatitis C virus (HCV) infection and hospitalisation, yet admissions are not utilised for HCV treatment initiation. We aimed to assess the extent to which people with HCV notification, including those with evidence of recent drug dependence, are hospitalised while eligible for direct-acting antiviral (DAA) therapy, and treatment uptake according to hospitalisation in the DAA era.

METHODS

We conducted a longitudinal, population-based cohort study of people living with HCV in the DAA era (March 2016-December 2018) through analysis of linked databases in New South Wales, Australia. Kaplan Meier estimates were used to report HCV treatment uptake by frequency, length, and cause-specific hospitalisation.

RESULTS

Among 57,467 people, 14,938 (26%) had evidence of recent drug dependence, 50% (n=7,506) of whom were hospitalised while DAA eligible. Incidence of selected cause-specific hospitalisation was highest for mental health-related (15.84 per 100 person-years [PY]), drug-related (15.20 per 100PY), and injection-related infectious disease (9.15 per 100PY) hospitalisations, and lowest for alcohol use disorder (4.58 per 100PY) and liver-related (3.13 per 100PY). 65% (n=4,898) of those hospitalised had been admitted >2 times and 46% (n=3,437) were hospitalised >7 days. By the end of 2018, DAA therapy was lowest for those hospitalised >2 times, for >7 days, and those whose first admission was for injection-related infectious disease, mental health disorders, and drug-related complications.

CONCLUSIONS

Among people who have evidence of recent drug dependence, frequent hospitalisation-particularly mental health, drug, and alcohol admissions-presents an opportunity for engagement in HCV care.

Is elimination of HCV in 2030 realistic in Central Europe

According to the recent data presented by Central-European HCV experts, the estimated prevalence of HCV is between 0.2% and 1.7% in certain countries in this region. There are no financial limitations to access to treatment in most countries. Patients in these countries have access to at least one pangenotypic regimen. The most common barriers to the elimination of HCV in Central Europe are a lack of established national screening programmes and limited political commitment to the elimination of HCV. Covid-19 has significantly affected the number of patients who have been diagnosed and treated, thus, delaying the potential elimination of HCV. These data suggest that the elimination of HCV elimination projected by WHO before 2030 will not be possible in the Central Europe.

Reinfection Following Successful Direct-acting Antiviral Therapy for Hepatitis C Virus Infection Among People Who Inject Drugs

BACKGROUND

The aim of this analysis was to calculate the incidence of hepatitis C virus (HCV) reinfection and associated factors among 2 clinical trials of HCV direct-acting antiviral treatment in people with recent injecting drug use or currently receiving opioid agonist therapy (OAT).

METHODS

Participants who achieved an end-of-treatment response in 2 clinical trials of people with recent injecting drug use or currently receiving OAT (SIMPLIFY and D3FEAT) enrolled between March 2016 and February 2017 in 8 countries were assessed for HCV reinfection, confirmed by viral sequencing. Incidence was calculated using person-time of observation and associated factors were assessed using Cox proportional hazard models.

RESULTS

Seventy-three percent of the population at risk of reinfection (n = 177; median age, 48 years; 73% male) reported ongoing injecting drug use. Total follow-up time at risk was 254 person-years (median, 1.8 years; range, 0.2-2.8 years). Eight cases of reinfection were confirmed for an incidence of 3.1/100 person-years (95% confidence interval [CI], 1.6-6.3) overall and 17.9/100 person-years (95% CI, 5.8-55.6) among those who reported sharing needles/syringes. Younger age and needle/syringe sharing were associated with HCV reinfection.

CONCLUSIONS

These data demonstrate the need for ongoing monitoring and improved strategies to prevent HCV reinfection following successful treatment among people with ongoing injecting drug use to achieve HCV elimination.

Identification and treatment of viral hepatitis C in persons who use drugs: a prospective, multicenter outreach study in Flanders, Belgium

BACKGROUND

Targeted screening for hepatitis C viral (HCV) infection is not yet widely executed in Belgium. When performed in people who use drugs (PWUD), it is mainly focused on those receiving opiate agonist therapy (OAT). We wanted to reach out to a population of difficult to reach PWUD not on centralized OAT, using non-invasive screening as a bridge to re-integration in medical care supported by facilitated referral to a specialist.

METHODS

This was a prospective, multicenter cohort study in PWUD not enrolled in a centralized OAT program in a community-based facility in Limburg or OAT program in a community-based facility in Antwerp, Belgium, from October 2018 until October 2019. Two study teams recruited participants using an outreach method at 18 different locations. Participants were tested for HCV antibodies (Ab) by finger prick, and risk factors were assessed through a face-to-face questionnaire. Univariate analyses were used to assess the association between HCV Ab and each risk factor separately. A generalized linear mixed model was used to investigate the association between the different risk factors and HCV.

RESULTS

In total, 425 PWUD were reached with a mean age of 41.6 ± 10.8, and 78.8% (335/425) were men. HCV Ab prevalence was 14.8% (63/425). Fifty-six (88.9%) PWUD were referred, of whom 37 (66.1%) were linked to care and tested for HCV RNA. Twenty-nine (78.4%) had a chronic HCV infection. Treatment was initiated in 17 (58.6%) patients. The adjusted odds for HCV Ab were highest in those with unstable housing 6 months before inclusion (p < .001, AOR 8.2 CI 95% 3.2-23.3) and in those who had ever shared paraphernalia for intravenous drug use (p < .001, AOR 6.2 CI 95% 2.5-16.0).

CONCLUSIONS

An important part tested positive for HCV. Treatment could be started in more than half of the chronically infected referred and tested positive for HCV-RNA. Micro-elimination is necessary to achieve the World Health Organization goals by 2030. However, it remains crucial to screen and link a broader group of PWUD to care than to focus solely on those who inject drugs.

Viral hepatitis C pandemic: Challenges and threats to its elimination

Under the WHO plan, the global elimination of the HCV pandemic is scheduled for 2030. The burden of HCV infection in developed countries is largely borne by people who inject drugs (PWID): new infections and reinfections are related to their risky behaviour. Although safe and sensitive hepatitis C diagnostic tools and directly acting antiviral medication are widely used, major challenges to disease elimination still remain in developed countries, where the WHO plan is in progress. The challenge is in the involvement and engagement of infected PWID. There is a strong need to change our uptake and treatment strategies to address all patients from the risk groups, connect them with the healthcare system and cure them with the vision to eliminate this HCV pandemic.

Hepatitis C treatment in a co-located mental health and alcohol and drug service using a nurse-led model of care

Hepatitis C virus (HCV) is more prevalent among people with experience of severe mental illness compared to the general population, due in part to higher levels of injecting drug use. Delivering HCV care through mental health services may reduce barriers to care and improve outcomes. A nurse-led HCV program was established in a co-located mental health and addiction service in Melbourne, Australia. People with a history of injecting drug use, including current use, were referred for HCV testing by nurses, with support provided on-site from a general practitioner and remotely from infectious disease and hepatology specialists. A nurse practitioner, general practitioner or specialists were able to prescribe HCV treatment. One-hundred and thirty people were referred to the nurse-led service, among whom 112 (86%) were engaged in care. Of those 112, 84 (75%) were found to have detectable HCV RNA, 70 (83%) commenced treatment; 28 (40%) prescriptions were nurse initiated, 19 (27%) were general practitioner initiated and 20 (29%) were prescribed from hospital clinics or elsewhere. All people with an SVR result (48/70) achieved HCV cure (intention to treat SVR 69%, per-protocol SVR 100%). Treatment commencement was highest among people prescribed opioid agonist therapy (28/29, 96%) compared to those who were not (18/26, 69%). In conclusion, a nurse-led, HCV service for people with severe mental illness including pathways to specialist support when needed can achieve high treatment uptake and cure. Further implementation work is required to improve treatment uptake, particularly among people not prescribed opioid agonist therapy, and to improve follow-up for SVR testing.

Cost-Utility of All-Oral Direct-Acting Antiviral Regimens for the Treatment of Genotype 1 Chronic Hepatitis C Virus-Infected Patients in Hong Kong

BACKGROUND

Direct-acting antivirals (DAAs) are entering the hepatitis C virus (HCV) treatment landscape in Hong Kong, prompting the need for cost-effectiveness evaluations of these interventions to enable optimal use of healthcare resources.

AIMS

This study aimed to compare the cost-effectiveness of DAAs to standard-of-care pegylated interferon plus ribavirin (RBV) in treatment-naïve patients without significant liver fibrosis and to compare different DAAs in patients who are treatment-experienced and/or have advanced liver disease.

METHODS

A Markov model was constructed to evaluate cost-effectiveness over a lifetime time horizon from the payer perspective. The target population was treatment-naïve and treatment-experienced HCV genotype 1 patients, stratified by degree of liver fibrosis. The model consists of 16 health states encompassing METAVIR fibrosis score (F0-F4), treatment success or failure, decompensated cirrhosis, hepatocellular carcinoma, liver transplant, and liver-related death. The proportions of patients achieving sustained virologic response were obtained from clinical trials. Other inputs were obtained from published and local data. The primary outcome was incremental cost-utility ratio for each DAA versus pegylated interferon + ribavirin and among different DAAs.

RESULTS

In treatment-naïve F0-2 HCV patients, all DAAs were cost-effective in genotype 1a and daclatasvir + asunaprevir, elbasvir/grazoprevir, ledipasvir/sofosbuvir, and glecaprevir/pibrentasvir were cost-effective compared to pegylated interferon + ribavirin in genotype 1b. In genotypes 1a and 1b, treatment-experienced patients, and F3-4 patients, elbasvir/grazoprevir was the least costly DAA and economically dominant over most other DAAs.

CONCLUSIONS

DAAs can be a cost-effective option for the treatment of genotype 1 HCV patients in Hong Kong, and elbasvir/grazoprevir is cost-effective.

Allocating treatment resources for hepatitis C in the UK: a constrained optimization modelling approach

Background and objective: Although the treatment of chronic hepatitis C (CHC) has significantly evolved with the introduction of direct-acting antivirals, the treatment uptake rates have been low especially among marginalized groups in the UK, such as people who inject drug (PWID) and men who have sex with men (MSM). Cutting health inequality is a major focus of healthcare agencies. This study aims to identify the optimal allocation of treatment budget for chronic hepatitis CHC among populations and treatments in the UK so that liver-related mortality in patients with CHC is minimized, given the constraint of treatment budget and equity issue. Methods: A constrained optimization modelling of resource allocation for the treatment of CHC was developed in Excel from the perspective of the UK National Health System over a lifetime horizon. The model was designated with the objective function of minimizing liver-related deaths by varying the decision variables, representing the number of patients receiving each treatment (elbasvir-grazoprevir, ombitasvir-paritaprevir-ritonavir-dasabuvir, sofosbuvir-ledipasvir, and pegylated interferon-ribavirin) in each population (the general population, PWID, and MSM). Two main constraints were formulated including treatment budget and the issue of equity. The model was populated with UK local data applying linear programming and underwent internal and external validation. Scenario analyses were performed to assess the robustness of model results. Results: Within the constraints of no additional funding over original spending in status quo and the consideration of the issue of equity among populations, the optimal allocation from the constrained optimization modelling (treating 13,122 PWID, 160 MSM, and 904 general patients with ombitasvir-paritaprevir-ritonavir-dasabuvir) was found to treat 2,430 more patients (relative change: 20.7%) and avert 78 liver-related deaths (relative change: 0.3%) compared with the current allocation. The number of patients receiving treatment increased 4,928 (relative change: 60.1%) among PWID and 42 (relative change: 35.8%) among MSM. Conclusion: The current allocation of treatment budget for CHC is not optimal in the UK. More patients would be treated, and more liver-related deaths would be avoided using a new allocation from a constrained optimization modelling without incurring additional spending and considering the issue of equity.

Concordance between self-reported and current hepatitis C virus infection status in a sample of people who inject drugs in Sydney and Canberra, Australia

INTRODUCTION

Awareness of hepatitis C virus (HCV) status among people who inject drugs is critical to ensure linkage to care and reduce transmission risk. Testing pathways, confusion about results and possible reinfection raise potential for discordance between perceived and actual HCV status among people who inject drugs. We evaluated self-reported and serologically confirmed HCV status concordance among a sample of Australian people who inject drugs.

METHODS

Data were collected in May-June 2018 from participants in Canberra and Sydney, Australia, who had injected drugs at least monthly in the past 6 months. Participants completed a structured interview assessing self-reported HCV status and provided a dried blood spot sample for HCV RNA testing.

RESULTS

Of 103 participants, 95% self-reported ever receiving antibody testing, 58% of whom reported having received RNA testing. Seventy-three percent of participants reported never having been told that they had HCV, 18% reported current infection and 9% did not know their current status. According to dried blood spot RNA testing, 20% were currently infected. Over a quarter of the sample (28%, n = 29) did not accurately report their HCV status, half of whom were unaware of a current infection.

DISCUSSION AND CONCLUSIONS

With over one-quarter of the sample in our study not accurately reporting their current HCV status, our findings reinforce the importance of regular testing for active infection, and the need for improved health literacy on HCV antibody and RNA test results, HCV status post-treatment and reinfection risk.

Directly Acting Antiviral-Based Treatment for HCV-Infected Persons Who Inject Drugs: A Multicenter Real-Life Study

BACKGROUND

We aimed to evaluate the factors associated with a virological response in a cohort of Hepatitis C virus (HCV)-infected people who inject drugs (PWID) treated with direct acting antivirals (DAAs).

METHODS

We conducted a multicenter retrospective cohort study enrolling HCV-infected PWID treated with DAAs. The primary outcome evaluated was the sustained virological response (SVR12) rate.

RESULTS

Five hundred and twenty HCV-infected PWID treated with all-oral DAA-based regimens were enrolled; a total of 168 (32.3%) patients presented genotype 1a, 109 (21.0%) genotype 1b, and 174 (33.5%) genotype 3; a total 152 of the 520 subjects (29.2%) were cirrhotics; a total 118 (22.7%) and 373 (71.7%) were treated with DAA regimens of second and third generation, respectively; a total 169 (33.6%) patients were receiving an opioid agonist at the start of antiviral therapy. Only 11 subjects (2.1%) did not show an SVR12. A significant correlation was found between treatment with opioid substitution therapy (p < 0.001), Human Immunodeficiency Virus (HIV) coinfection (p = 0.002), and treatment with first- or second-generation regimens (p = 0.0015) and HCV failure. Upon multivariate analysis, treatment with a first- or second-generation DAA was the only factor independently associated with failure (OR 10.4, 95% CI: 1.43 to 76.1, p = 0.02).

CONCLUSIONS

Treatment with DAAs led to a high SVR12 rate (97.9%) in a large cohort of HCV-infected PWID. The only predictor of viral failure found in our analysis was treatment with first- and second-generation DAA.

Loss to follow-up in the hepatitis C care cascade: A substantial problem but opportunity for micro-elimination

Since the advent of direct-acting antivirals, elimination of hepatitis C viral (HCV) infections seems within reach. However, studies on the HCV cascade of care show suboptimal progression through each step for all patient groups. Loss to follow-up (LTFU) is a major issue and is a barrier to HCV elimination. This review summarizes the scale of the LTFU problem and proposes a micro-elimination approach. Retrieving LTFU patients and re-engaging them with care again has shown to be feasible in the Netherlands. Micro-elimination through retrieval can contribute to reaching the World Health Organization's viral hepatitis elimination targets by 2030.

Contemporary Epidemiology of Chronic Liver Disease and Cirrhosis

BACKGROUND & AIMS

Accurate estimates for the contemporary burden of chronic liver disease (CLD) are vital for setting clinical, research, and policy priorities. We aimed to review the incidence, prevalence, and mortality of CLD and its resulting complications, including cirrhosis and hepatocellular carcinoma (HCC).

METHODS

We reviewed the published literature on the incidence, prevalence, trends of various etiologies of CLD and its resulting complications. In addition, we provided updated data from the Centers for Disease Control and Global Burden of Disease Study on the morbidity and mortality of CLD, cirrhosis, and hepatocellular carcinoma (HCC). Lastly, we assessed the strengths and weaknesses of available sources of data in hopes of providing important context to these national estimates of cirrhosis burden.

RESULTS

An estimated 1.5 billion persons have CLD worldwide and the age-standardized incidence of CLD and cirrhosis is 20.7/100,000, a 13% increase since 2000. Similarly, cirrhosis prevalence and mortality has increased in recent years in the United States. The epidemiology of CLD is shifting, reflecting implementation of large-scale hepatitis B vaccination and hepatitis C treatment programs, the increasing prevalence of the metabolic syndrome, and increasing alcohol misuse.

CONCLUSIONS

The global burden of CLD and cirrhosis is substantial. Although vaccination, screening, and antiviral treatment campaigns for hepatitis B and C have reduced the CLD burden in some parts of the world, concomitant increases in injection drug use, alcohol misuse, and metabolic syndrome threaten these trends. Ongoing efforts to address CLD-related morbidity and mortality require accurate contemporary estimates of epidemiology and outcomes.

Applying a diffusion of innovations framework to the scale-up of direct-acting antiviral therapies for hepatitis C virus infection: Identified challenges for widespread implementation

BACKGROUND AND AIMS

Interferon-free, direct-acting antivirals (DAAs) for hepatitis C virus (HCV) offer much promise to achieve World Health Organization targets by 2030. However, impediments at the practitioner and health-system level will continue to obstruct the scale-up of DAAs worldwide unless identified and acted upon. Applying a diffusion of innovations framework, the aim of this study was to identify structural factors impacting practitioner experiences of managing HCV treatment.

METHODS

In-depth, semi-structured, telephone interviews took place between September 2018 and April 2019 to investigate barriers and facilitators for engaging in HCV management and DAA therapy amongst general practitioners (GPs) who prescribe opioid agonist therapy and drug and alcohol specialists in Australia. Interviews were transcribed verbatim, de-identified, and coded, and data were analysed with iterative categorisation and thematic analysis using Everett Rogers's diffusion of innovation framework.

RESULTS

amongst 30 participants (12 GPs, 18 drug and alcohol specialists), several structural factors were reported to impede practitioner efforts to deliver optimal HCV care. Two primary themes were explored: contextual factors for the diffusion of DAA therapies, including attempts by participants to shift clinic culture and respond to siloed health structures, and adopter factors. Some participants chose to 'rock the boat' by circumventing clinic protocol and HCV guidelines to treat more clients, effectively shifting adopter categories to become greater advocates in HCV care. Also, while a role for GPs as the 'new adopters' in HCV management was discussed, many participants expressed uncertainty as to how much GPs should become involved in the diffusion of DAA therapies more widely.

CONCLUSIONS

Reducing the global burden of HCV infection will not be possible without the widespread delivery of HCV treatment amongst practitioners. Practitioners and health workers require leadership and resources from health authorities so that the individual and population-level benefits of DAA therapy are realised.

Hospital discharges of hepatocellular carcinoma and non-alcohol related cirrhosis in the EU/EEA and United Kingdom: a descriptive analysis of 2004-2015 data

BACKGROUND

Viral hepatitis is a leading cause of mortality globally, comparable to that of HIV and TB. Most hepatitis deaths are related to liver cirrhosis and hepatocellular carcinoma (HCC) associated with chronic hepatitis B and C infections. To examine the progress towards the elimination goals set in the global health sector strategy for viral hepatitis, we aimed to assess the impact of mortality-indicative morbidity.

METHODS

We retrieved inpatients and day cases hospital discharges data from the Eurostat hospital activities database, and analysed ICD-10 and ICD-9 specific codes related to primary HCC and non-alcohol related cirrhosis registered by European Union/European Economic Area (EU/EEA) countries and United Kingdom (UK) for 2004 to 2015.

RESULTS

In 2015, 20 countries (45.7% of total EU/EEA/UK population) reported 13,236 (Range 0-6294) day cases and 36,012 (4-9097) inpatients discharges of HCC. Romania, Croatia, Luxembourg and UK reported increasing day cases discharge rates between 2004 and 2015; while HCC inpatients discharge rates increased overall during this period. There were 13,865 (0-5918) day cases and 56,176 (3-29,118) inpatients discharges reported for cirrhosis across the 20 countries in 2015. Over the 12 years, day cases discharge rates for cirrhosis increased in Romania, Croatia and UK. Though higher than for day cases, cirrhosis inpatients discharge rates remained stable.

CONCLUSIONS

The hospital burden of HCC and cirrhosis is high, with considerable inpatient load including sustained increasing trends in HCC discharge rates. Further interpretation in light of local health system contexts, and more robust harmonised data are needed to better understand the impact of the viral hepatitis epidemic in the region.

The Hep-CORE policy score: A European hepatitis C national policy implementation ranking based on patient organization data

BACKGROUND

New hepatitis C virus (HCV) treatments spurred the World Health Organization (WHO) in 2016 to adopt a strategy to eliminate HCV as a public health threat by 2030. To achieve this, key policies must be implemented. In the absence of monitoring mechanisms, this study aims to assess the extent of policy implementation from the perspective of liver patient groups.

METHODS

Thirty liver patient organisations, each representing a country, were surveyed in October 2018 to assess implementation of HCV policies in practice. Respondents received two sets of questions based on: 1) WHO recommendations; and 2) validated data sources verifying an existing policy in their country. Academic experts selected key variables from each set for inclusion into policy scores. The similarity scores were calculated for each set with a multiple joint correspondence analysis. Proxy reference countries were included as the baseline to contextualize results. We extracted scores for each country and standardized them from 0 to 10 (best).

RESULTS

Twenty-five countries responded. For the score based on WHO recommendations, Bulgaria had the lowest score whereas five countries (Cyprus, Netherlands, Portugal, Slovenia, and Sweden) had the highest scores. For the verified policy score, a two-dimensional solution was identified; first dimension scores pertained to whether verified policies were in place and second dimension scores pertained to the proportion of verified policies in-place that were implemented. Spain, UK, and Sweden had high scores for both dimensions.

CONCLUSIONS

Patient groups reported that the European region is not on track to meet WHO 2030 HCV goals. More action should be taken to implement and monitor HCV policies.

Decentralized, Community-Based Hepatitis C Point-of-Care Testing and Direct-Acting Antiviral Treatment for People Who Inject Drugs and the General Population in Myanmar: Protocol for a Feasibility Study

Background

The advent of direct-acting antivirals (DAAs) and point-of-care (POC) testing platforms for hepatitis C allow for the decentralization of care to primary care settings. In many countries, access to DAAs is generally limited to tertiary hospitals, with limited published research documenting decentralized models of care in low-and middle-income settings.

Objective

This study aims to assess the feasibility, acceptability, effectiveness, and cost-effectiveness of decentralized community-based POC testing and DAA therapy for hepatitis C among people who inject drugs and the general population in Yangon, Myanmar.

Methods

Rapid diagnostic tests for anti-hepatitis C antibodies were carried out on-site and, if reactive, were followed by POC GeneXpert hepatitis C RNA polymerase chain reaction tests. External laboratory blood tests to exclude other major health issues were undertaken. Results were given to participants at their next appointment, with the participants commencing DAA therapy that day if a specialist review was not required. Standard clinical data were collected, and the participants completed behavioral questionnaires. The primary outcome measures are the proportion of participants receiving GeneXpert hepatitis C RNA test, the proportion of participants commencing DAA therapy, the proportion of participants completing DAA therapy, and the proportion of participants achieving sustained virological response 12 weeks after completing DAA therapy.

Results

Recruitment was completed on September 30, 2019. Monitoring visits and treatment outcome visits are scheduled to continue until June 2020.

Conclusions

This feasibility study in Myanmar contributes to the evidence gap for community-based hepatitis C care in low- and middle-income settings. Evidence from this study will inform the scale-up of hepatitis C treatment programs in Myanmar and globally.

Eliminating Structural Barriers: The Impact of Unrestricted Access on Hepatitis C Treatment Uptake Among People Living With Human Immunodeficiency Virus

BACKGROUND

High costs of direct-acting antivirals (DAAs) have led health-care insurers to limit access worldwide. Using a natural experiment, we evaluated the impact of removing fibrosis stage restrictions on hepatitis C (HCV) treatment initiation rates among people living with human immunodeficiency virus (HIV), and then examined who was left to be treated.

METHODS

Using data from the Canadian HIV-HCV Coinfection Cohort, we applied a difference-in-differences approach. Changes in treatment initiation rates following the removal of fibrosis stage restrictions were assessed using a negative binomial regression with generalized estimating equations. The policy change was then specifically assessed among people who inject drugs (PWID). We then identified the characteristics of participants who remained to be treated using a modified Poisson regression.

RESULTS

Between 2010-2018, there were a total of 585 HCV initiations among 1130 eligible participants. After removing fibrosis stage restrictions, DAA initiations increased by 1.8-fold (95% confidence interval [CI] 1.3-2.4) controlling for time-invariant differences and secular trends. Among PWID the impact appeared even stronger, with an adjusted incidence rate ratio of 3.6 (95% CI 1.8-7.4). However, this increased treatment uptake was not sustained. At 1 year following universal access, treatment rates declined to 0.8 (95% CI .5-1.1). Marginalized participants (PWID and those of indigenous ethnicity) and those disengaged from care were more likely to remain HCV RNA positive.

CONCLUSIONS

After the removal of fibrosis restrictions, HCV treatment initiations nearly doubled immediately, but this treatment rate was not sustained. To meet the World Health Organization elimination targets, the minimization of structural barriers and adoption of tailored interventions are needed to engage and treat all vulnerable populations.

Cost-effectiveness of second-generation direct-acting antiviral agents in chronic HCV infection: a systematic literature review

BACKGROUND

Our objectives were to review the economic modelling methods and cost-effectiveness of second-generation direct-acting antiviral agents for the treatment of chronic HCV infection.

METHODS

A systematic literature search was performed in February 2017 using Scopus and OVID to review relevant publications between 2011 to present. Two independent reviewers screened potential papers.

RESULTS

The database search resulted in a total of 1,536 articles; after deduplication, title/abstract and full text screening, 67 studies were included for qualitative analysis. The vast majority of studies were conducted in high-income countries (n=59) and used Markov-based modelling techniques (n=60). Most of the analyses utilized long-term time horizons; 58 studies calculated lifetime costs and outcomes. The examined treatments were heterogenic among the studies; seven analyses did not directly evaluate treatments (just with screening or genotype testing). The examined treatments (n=60) were either dominant (23%), or cost-effective at base case (57%) or in given subgroups (18%). Only one (2%) study reported that the assessed treatment was not cost-effective with the given setting and price.

CONCLUSIONS

Despite their high initial therapeutic costs, second-generation direct-acting antiviral agents were found to be cost-effective to treat chronic HCV infection. Studies were predominantly conducted in higher income countries, although we have limited information on cost-effectiveness in low- and middle-income countries, where assessment of cost-effectiveness is even more essential due to more limited health-care resources and potentially higher public health burden due to unsafe medical interventions.

Price of a hepatitis C cure: Cost of production and current prices for direct-acting antivirals in 50 countries

Objectives

Seven years after the introduction of direct-acting antivirals (DAAs) for the treatment of hepatitis C, high prices remain a barrier for treatment programs worldwide. This study seeks to describe current prices for originator DAAs in 50 countries and evaluate the relationship between prices and GDP per capita.

Methods

Data on prices of sofosbuvir, daclatasvir, sofosbuvir/ledipasvir, sofosbuvir/velpatasvir, and glecaprevir/pibrentasvir were collected from national databases for 50 countries. Cost-based generic prices were estimated using an established algorithm, which accounts for costs of the active pharmaceutical ingredient (API), excipients, conversion costs of API to finished pharmaceutical product, taxes assuming manufacture in India, and a 10% profit margin. Correlation between current market prices and GDP per capita was assessed by Spearman rank-order correlation.

Results

Median originator prices per standard course were US$40,502 for sofosbuvir, US$26,928 for daclatasvir, US$46,812 for sofosbuvir/ledipasvir, US$34,381 for sofosbuvir/velpatasvir, and US$30,710 for glecaprevir/pibrentasvir (G/P). The estimated cost-based generic prices for a 12-week course were US$28 for sofosbuvir, US$31 for ledipasvir, US$58 for velpatasvir, US$4 for daclatasvir. For fixed-dose combinations, estimated cost-based prices were US$58 for sofosbuvir/ledipasvir, US$85 for sofosbuvir/velpatasvir, and US$31 for sofosbuvir/daclatasvir (API cost data were insufficient to calculate an estimate for G/P). Cumulative originator sales of WHO-recommended DAAs reached US$82 billion by the end of 2019. Across the 50 countries, there was no correlation between GDP per capita and DAA price, nor between estimated viraemic population and DAA price. Sub-analyses within World Bank income groups found a significant negative correlation between price and GDP per capita for all DAAs within the high-income countries group.

Conclusions

Prices of DAAs vary widely across countries. The lack of correlation between DAA price and GDP per capita and viraemic population suggests that prices for DAAs are not adjusted based on country income level or potential patient population. Among high-income countries, DAA prices fall as income levels rise, possibly due to greater negotiating power of wealthier countries. DAA prices in most countries remain many times higher than estimated cost-based generic prices.

Progress Toward Hepatitis C Virus Elimination: Therapy and Implementation

The World Health Organization has called for the elimination of hepatitis C virus (HCV) as a public health threat by 2030. Highly effective direct-acting antiviral agents provide the therapeutic tools required for elimination. In the absence of a vaccine, HCV elimination will require enhanced primary prevention and an increase in the proportions of people diagnosed and treated. Given that globally only 20% of people with chronic HCV are diagnosed, and around 5% have initiated HCV treatment, the task ahead is enormous. But, global public health needs optimism, and countries currently on track for HCV elimination provide a pathway forward.
