Abstract
BACKGROUND Injection drug use (IDU) is a risk factor for hepatitis C virus (HCV) acquisition and occurs disproportionately among women who exchange sex (WES). However, little is known about HCV epidemiology in this population. We estimated HCV seroprevalence, identified correlates of HCV seropositivity, and characterized social networks by HCV serostatus and IDU history among WES in the Seattle, Washington, area. METHODS This was a secondary analysis of data from the 2016 National HIV Behavioral Surveillance survey in the Seattle, Washington area, a cross-sectional survey that used respondent-driven sampling (RDS) to enroll WES for money or drugs (N = 291). All participants were offered rapid HCV-antibody testing. We estimated HCV seropositivity and used log regression methods to estimate crude and adjusted prevalence ratios (PRs) for correlates of HCV seropositivity among WES. Using RDS recruitment chain data, we computed homophily indices to estimate the extent to which participants were likely to recruit another participant with the same HCV serostatus and IDU history. RESULTS In the study sample of WES in the Seattle, Washington area, 79% reported lifetime IDU and 60% were HCV seropositive. HCV seropositivity was strongly associated with ever injecting drugs (PRadj: 7.7 [3.3, 18.0]). The RDS homophily scores for HCV seropositivity (0.07) and ever injecting drugs (0.02) suggested that participants did not tend to recruit others with the same characteristics beyond what would be expected by chance. CONCLUSION Among this sample of WES in Seattle, Washington area, HCV seroprevalence was high and strongly associated with a history of IDU. The high burden of HCV among WES suggests this marginalized group would benefit from additional harm reduction services and targeted HCV treatment campaigns to reduce forward transmission. We saw little evidence of preferential recruitment among WES who were HCV seropositive or reported a history of IDU, suggesting the potential futility of peer-based referrals for HCV 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
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
Chronic hepatitis C virus (HCV) infection is a leading cause of cirrhosis worldwide and kills more Americans than 59 other infections, including HIV and tuberculosis, combined. While direct-acting antiviral (DAA) treatments are effective, limited uptake of therapy, particularly in high-risk groups, remains a substantial barrier to eliminating HCV. We developed a long-acting DAA system (LA-DAAS) capable of prolonged dosing and explored its cost-effectiveness. We designed a retrievable coil-shaped LA-DAAS compatible with nasogastric tube administration and the capacity to encapsulate and release gram levels of drugs while resident in the stomach. We formulated DAAs in drug-polymer pills and studied the release kinetics for 1 mo in vitro and in vivo in a swine model. The LA-DAAS was equipped with ethanol and temperature sensors linked via Bluetooth to a phone application to provide patient engagement. We then performed a cost-effectiveness analysis comparing LA-DAAS to DAA alone in various patient groups, including people who inject drugs. Tunable release kinetics of DAAs was enabled for 1 mo with drug-polymer pills in vitro, and the LA-DAAS safely and successfully provided at least month-long release of sofosbuvir in vivo. Temperature and alcohol sensors could interface with external sources for at least 1 mo. The LA-DAAS was cost-effective compared to DAA therapy alone in all groups considered (base case incremental cost-effectiveness ratio $39,800). We believe that the LA-DAA system can provide a cost-effective and patient-centric method for HCV treatment, including in high-risk populations who are currently undertreated.

Abstract
Exclusive HCV therapy clinical trials with genotype 6 patients in high prevalence areas have been sparse. We analysed the safety and efficacy of two generic, pangenotypic NS5A/NS5B combination oral DAA regimens, primarily in genotypes 3 and 6, in a real-world setting: (a) daclatasvir/sofosbuvir (DCV/SOF) ± ribavirin (RBV) and (b) Velpatasvir/sofosbuvir (VEL/SOF ± RBV). Between December 2015 and November 2017, data from 522 patients were analysed, 311 of whom were treated with DCV/SOF ± RBV for 12/24 weeks (genotype 3: n = 193, genotype 6: n = 89) and 211 were treated with VEL/SOF ± RBV for 12/24 weeks (genotype 3: n = 83, genotype 6: n = 77). Overall SVR rates were high for both DCV/SOF ± RBV (96.1%, n = 299/311) and VEL/SOF ± RBV (95.3%, n = 201/211), and there was a good adverse event profile. Treatment naïve status and inclusion of RBV (in advanced fibrosis/cirrhosis) were significant independent predictors of achieving SVR12, while type of DAA regimen was not predictive. In this large cohort of genotypes 3 (n = 276) and 6 (n = 166; n = 127 unique subtype of 6c-l), high SVR rates of 94.9% (n = 262/276) and 95.2% (n = 158/166), respectively, were noted. In conclusion, generic and pangenotypic DCV/SOF and VEL/SOF ± RBV regimens were highly effective and safe, in genotypes 3 and 6 chronic HCV in Myanmar. These efficacious pangenotypic regimens suggest that baseline genotype testing can be eliminated moving forward. While RBV may still be needed for those with advanced fibrosis/cirrhosis, in a global elimination strategy it would not be practical even if it does compromise SVR in a minority with difficult to treat characteristics.

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 In resource-constrained areas, generic direct-acting antivirals (DAAs) have considerably reduced the cost of hepatitis C virus (HCV) therapy while there remain significant costs related to the baseline and follow-up virologic assays. AIM The aim was to assess the efficacy and safety of HCV therapy in Myanmar with pan-genotypic generic DAA sofosbuvir/velpatasvir (SOF/VEL) and with and without the baseline genotype testing, while the duration of treatment and use of ribavirin (RBV) was dictated by cirrhosis and prior treatment failure. METHODS Between September 2016 and June 2017, data from the 359 participants who completed treatment with SOF/VEL (± RBV) for 12-24 weeks were analyzed. Two hundred one patients did not have the baseline HCV genotype tested. RESULTS Regimens included SOF/VEL for 12 weeks (n = 43), SOF/VEL/RBV for 12 weeks (n = 275), or SOF/VEL/RBV for 24 weeks (n = 41). The mean age was 52 years, 44% were men (n = 159), 41 (11.4%) had a history of previous DAA therapy, 7 (1.9%) had a history of hepatocellular carcinoma, and 55 (15.3%) had cirrhosis. Overall, the sustained viral response (SVR)12 rate was 98.6% (354/359) and with a good adverse event profile. SVR rates were similar to those with and without baseline genotype testing and also across all genotypes in those who had genotype tested. CONCLUSIONS In Myanmar, generic and pan-genotypic SOF/VEL ± RBV is a highly effective and safe treatment for HCV, regardless of the HCV genotype, and therefore, the requirement for the baseline genotype can be eliminated. Future strategies should include elimination of treatment and end of treatment HCV RNA testing to enhance treatment uptake and further reduce cost.

Abstract
People who inject drugs (PWID) are a key high-risk group for Hepatitis C Virus (HCV) infection due to the sharing of needles and drug-preparation equipment. However, only approximately 50% of PWID are currently screened for HCV in Switzerland. At present, screening of PWID occurs in general practice via venepuncture. Compared to venepuncture, screening via rapid antibody saliva and dried blood spot (DBS) tests is well adapted to PWID, who typically have difficult venous access. The cost-effectiveness of an increased access screening programme of PWID (increased screening using rapid antibody saliva tests and DBS tests [semi-quantitative viraemia and viral genotype]) was analysed through a decision tree screening model combined with the outputs of a Markov treatment model. Sensitivity and scenario analyses examined the uncertainty of results. At a willingness to pay (WTP) threshold of CHF 100 000 (USD 105 000) per quality-adjusted life year (QALY), the increased access screening programme was cost-effective compared to current screening, with a base case incremental cost-effectiveness ratio of CHF 7 940 (USD 8337) per QALY. The net monetary benefit was CHF 959 802 668 (USD 1 007 792 801) for the PWID population and CHF 94 469 (USD 99 192) per person. The increased access screening programme had a 97.0% probability of being cost-effective compared to the current screening method at the WTP threshold of CHF 100 000 (USD 105 000). The results showed an increased access screening programme that uses tests which are better suited to the PWID population to be more cost-effective, due to the increased uptake that rapid antibody saliva and DBS tests generate.

Abstract
BACKGROUND Data are sparse on treatment of chronic hepatitis C virus (HCV) in cancer patients. We evaluated the efficacy and safety of sofosbuvir-based therapy (SOFBT) in cancer patients. METHODS Patients treated with SOFBT at our center during 2014-2017 were included in a prospective observational study. Efficacy [sustained virologic response at 12 weeks after the end of treatment (SVR12)], cancer-related outcomes and adverse events (AEs) were assessed. RESULTS We included 153 patients. Most were men (109; 71%), white (92; 60%), non-cirrhotic (105; 69%), and with HCV genotype 1 (110; 72%). The most common cancers were hepatocellular carcinoma (HCC) (27; 18%) and multiple myeloma (14; 9%). The overall SVR12 rate was 91% (128/141). SVR12 was 100% in patients treated with ledipasvir/sofosbuvir for 8 weeks. Of the 32 patients initially excluded from cancer clinical trials because of HCV, 27 (84%) were granted cancer therapy access after starting SOFBT. Six patients with indolent non-Hodgkin's lymphoma (NHL) received SOFBT without cancer treatment. Two achieved complete remission, one had partial remission, and two had stable cancer. Within 6 months after SOFBT, 5% (6/121) of patients in remission or with stable cancer, had progression or recurrence (two with HCC and one each with esophageal cancer, cholangiocarcinoma, NHL, and tonsillar cancer). No de novo HCCs occurred. AEs were most commonly grade 1-2 (90%). CONCLUSIONS SOFBT in HCV-infected cancer patients is effective and safe, may permit access to investigational cancer therapy expanding treatment options, may induce remission of NHL, and may be used for 8 weeks.

Abstract
OBJECTIVE To investigate the efficacy and safety of sofosbuvir (SOF) plus daclatasvir (DCV) or simeprevir (SMV) in a randomized, open-label, noninferiority trial of patients infected with hepatitis C virus genotype 1, who were previously unresponsive to pegylated interferon and ribavirin or were treatment naive. METHODS Patients were randomly assigned to receive SOF (400 mg once daily) plus DCV (60 mg once daily) or SMV (150 mg once daily) for 12 weeks. The analysis included all participants who received at least one dose of the study drugs. The primary endpoint was sustained virologic response 12 weeks after ending treatment (SVR12; hepatitis C virus RNA measured using COBAS TaqMan RT-PCR (lower limit of detection and quantification of 12 UI/mL)). This study was registered at ClinicalTrials.gov (NCT02624063). RESULTS A total of 125 of 127 enrolled and randomized patients started treatment (n = 65 SOF + DCV; n = 60 SOF + SMV). SVR12 was attained in 121 patients (96.8%): 65 (100%) receiving SOF + DCV (95% confidence interval (CI), 94.5 to 100) and 56 (93.3%) receiving SOF + SMV (95% CI, 83.8 to 98.2; absolute difference, 6.6%; 95% CI, -15.0 to 0). The most common adverse events were fatigue (n = 32, 25.6%), headache (n = 27, 21.6%), and mood swings (n = 24, 19.2%). No patients discontinued therapy. CONCLUSIONS The overall SVR rate was 96.9%; SOF + DCV (100%) was higher than that of SOF + SMV (93.3%). Despite no statistically significant intergroup difference in SVR12 rates, the noninferiority of SOF + SMV to SOF + DCV could not be established because the difference in efficacy was clinically relevant.

Absolute Insurer Denial of Direct-Acting Antiviral Therapy for Hepatitis C: A National Specialty Pharmacy Cohort Study. Open Forum Infect Dis 2018; 5:ofy076. [PMID: 29977955 PMCID: PMC6016397 DOI: 10.1093/ofid/ofy076] [Citation(s) in RCA: 66] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2017] [Accepted: 04/11/2018] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Despite the availability of new direct-acting antiviral (DAA) regimens, changes in DAA reimbursement criteria, and a public health focus on hepatitis C virus (HCV) elimination, it remains unclear if public and private insurers have increased access to these therapies over time. We evaluated changes in the incidence of absolute denial of DAA therapy over time and by insurance type. METHODS We conducted a prospective cohort study among patients who had a DAA prescription submitted from January 2016 to April 2017 to Diplomat Pharmacy, Inc., which provides HCV pharmacy services across the United States. The main outcome was absolute denial of DAA prescription, defined as lack of fill approval by the insurer. We calculated the incidence of absolute denial, overall and by insurance type (Medicaid, Medicare, commercial), for the 16-month study period and each quarter. RESULTS Among 9025 patients from 45 states prescribed a DAA regimen (4702 covered by Medicaid, 1821 Medicare, 2502 commercial insurance), 3200 (35.5%; 95% confidence interval, 34.5%-36.5%) were absolutely denied treatment. Absolute denial was more common among patients covered by commercial insurance (52.4%) than Medicaid (34.5%, P < .001) or Medicare (14.7%, P < .001). The incidence of absolute denial increased across each quarter of the study period, overall (27.7% in first quarter to 43.8% in last quarter; test for trend, P < .001) and for each insurance type (test for trend, P < .001 for each type). CONCLUSIONS Despite the availability of new DAA regimens and changes in restrictions of these therapies, absolute denials of DAA regimens by insurers have remained high and increased over time, regardless of insurance type.

Abstract
Purpose of Review Direct-acting antiviral regimens for chronic hepatitis C virus (HCV) became available in 2014, and these highly curative therapies have the potential to reduce HCV-associated morbidity and mortality, decrease transmission, and eliminate HCV infection as a public health problem. This review summarizes the recommendations by the National Academies of Sciences, Engineering, and Medicine for a US strategy for HCV elimination. Recent Findings To achieve proposed targets of reducing HCV incidence by 90% and decreasing HCV-related mortality by 60% by 2030, there is a critical need to improve HCV diagnosis and linkage to care; reduce HCV-related disease by antiviral treatment scale-up; reduce HCV incidence; and strengthen HCV surveillance to determine achievement of HCV elimination targets over time. Summary While HCV elimination is feasible, success of this national effort will require ongoing collaboration and critical resource investment by key stakeholders, including medical and public health communities, legislators, community organizers, and patient advocates.
