Cascade of care for migrants tested Hepatitis C antibodies positive in France through a systematic screening programme: The PRECAVIR study

Migration of people from HCV endemic countries is a public health issue for the French healthcare system. The PRECAVIR study focused on migrant patients and provides a multidisciplinary, patient‐centred approach to treat chronic HCV‐infected migrants through a systematic screening programme. Between 2007 and 2017, 101 (2.98%) out of 3386 consecutive adult migrants attending two primary healthcare settings in Créteil, France, tested positive for HCV. The median age was 44.5 years old, and 55% were women. Patients were mainly from sub‐Saharan Africa, Eastern Europe and Asia. Seventy‐four patients were undocumented migrants, and 25 were asylum seekers. Eighty‐four (83%) patients were unaware of their serological status. All patients were offered referral to a specialist in the same setting. HCV RNA testing was performed in 88 (87%) of the patients who tested anti‐HCV positive. Forty‐nine (57%) were chronically infected, while 39 (43%) had an undetectable viral load. All patients were treatment‐naïve. More than half of patients had access to treatment. Before 2014, thirteen patients were treated with pegylated interferon and ribavirin, and an SVR was achieved in 8 (61.5%) of them. By 2017, 17 patients had begun oral, direct‐acting antiviral treatment. An SVR was achieved in 16 of 17 patients (93%). However, all patients not initially eligible for treatment were lost to follow‐up. This study showed the effectiveness of a coordinated care network when anti‐HCV testing, linkage to care and treatment are organized for a migrant population in the same setting as long as universal treatment makes a test and treat policy possible.     

The Hepatitis C virus treatment cascade at an urban postincarceration transitions clinic

Transitions clinics, which provide medical care to individuals who have been released from incarceration, reach a population at high risk for hepatitis C Virus (HCV) infection. We used the HCV treatment cascade to describe HCV care at an urban postincarceration transitions clinic, identifying gaps in care and determining reasons for lapses in care. In this retrospective cohort study, we reviewed electronic health records for all formerly incarcerated individuals receiving care at the Bronx Transitions Clinic. HCV treatment cascade measures included the following: detection of HCV antibodies, confirmation of chronic infection, specialist referral, specialist evaluation, initiation of treatment, completion of treatment and achievement of SVR. We recorded reasons for lapses in care. Of 451 patients accessing care, 317 (70%) were screened for HCV antibodies, and 106 (33%) tested positive. Of the 106 antibody‐positive patients, 93 (88%) were evaluated for HCV viremia and 84 (79%) were confirmed to have chronic HCV infection; 19% of the total sample had chronic HCV infection. Of these 84 with chronic HCV, 48 (57%) received specialist referral, 30 (36%) were evaluated, 8 (10%) initiated treatment, and 5 (6%) completed treatment and achieved SVR. Some treatment lapses occurred because patients were deemed unstable for treatment (12%) or were re‐incarcerated (5%). Chronic HCV infection was common among transitions clinic patients. Few were treated and cured. Patients lost contact with providers before consideration for antiviral therapy. Referral to specialty providers was a gap in care. Increasing HCV treatment in this population will likely require intensive delivery models.     

Sofosbuvir plus ribavirin in Japanese patients with chronic genotype 2 HCV infection: an open‐label,phase 3 trial

Genotype 2 hepatitis C virus (HCV) accounts for up to 30% of chronic HCV infections in Japan. The standard of care for patients with genotype 2 HCV – peginterferon and ribavirin for 24 weeks – is poorly tolerated, especially among older patients and those with advanced liver disease. We conducted a phase 3, open‐label study to assess the efficacy and safety of an all‐oral combination of the NS5B polymerase inhibitor sofosbuvir and ribavirin in patients with chronic genotype 2 HCV infection in Japan. We enrolled 90 treatment‐naïve and 63 previously treated patients at 20 sites in Japan. All patients received sofosbuvir 400 mg plus ribavirin (weight‐based dosing) for 12 weeks. The primary endpoint was sustained virologic response at 12 weeks after therapy (SVR12). Of the 153 patients enrolled and treated, 60% had HCV genotype 2a, 11% had cirrhosis, and 22% were over the aged 65 or older. Overall, 148 patients (97%) achieved SVR12. Of the 90 treatment‐naïve patients, 88 (98%) achieved SVR12, and of the 63 previously treated patients, 60 (95%) achieved SVR12. The rate of SVR12 was 94% in patients with cirrhosis and in those aged 65 and older. No patients discontinued study treatment due to adverse events. The most common adverse events were nasopharyngitis, anaemia and headache. Twelve weeks of sofosbuvir and ribavirin resulted in high rates of SVR12 in treatment‐naïve and previously treated patients with chronic genotype 2 HCV infection. The treatment was safe and well tolerated by patients, including the elderly and those with cirrhosis.     

Effectiveness of direct-acting antiviral therapy among Aboriginal and Torres Strait Islander peoples with HCV infection in Australia: A national real-world cohort (REACH-C)

Aboriginal and Torres Strait Islander peoples experience a disproportionate burden of hepatitis C virus (HCV) infection. This study assessed the effectiveness of direct-acting antiviral (DAA) therapy among Aboriginal peoples in the three years following universal access in Australia. REACH-C, a national multicentre prospective cohort study, evaluated HCV treatment outcomes from sequential DAA initiations across 33 health services between March 2016 and June 2019. DAA effectiveness was assessed by sustained virological response (SVR) in the total (full analysis set) and effectiveness (modified analysis set excluding those lost to follow-up) populations. Overall, 915 (10%) Aboriginal and 8095 (90%) non-Indigenous people commenced DAA therapy, of whom 30% and 16% reported current injecting drug use and 73% and 42% were treated in primary care, respectively. SVR in the total and effectiveness populations was 74% and 94% among Aboriginal people and 82% and 94% among non-Indigenous people, with loss to follow-up contributing to lower SVR in the total population analysis (22% Aboriginal, 13% non-Indigenous). Among Aboriginal people, returning for follow-up was positively associated with older age (aOR 1.20; 95% CI 1.04, 1.39) and SVR was negatively associated with cirrhosis (aOR 0.39; 95% CI 0.19, 0.80) and prior DAA treatment (aOR 0.14; 95% CI 0.04, 0.49). Factors reflecting higher vulnerability or inequity were not associated with returning for testing or SVR. DAA therapy was highly effective among Aboriginal peoples with HCV treated through primary and tertiary services. Tailored community-led interventions are necessary to optimize follow-up and engagement. Sustained DAA uptake and equitable access to care, treatment and prevention are required for HCV elimination.     

Randomized trial of interferon beta-1a with or without ribavirin in Asian patients with chronic hepatitis C

The standard of care for chronic hepatitis C virus (HCV) infection, pegylated interferon (IFN) alpha plus ribavirin, results in a sustained virologic response (SVR) in approximately 50%-60% of patients. IFN beta is a potential alternative to IFN alpha. The aim of this study was to investigate the efficiency and durability of IFN beta and its combination with ribavirin in the na?ve setting of chronic hepatitis C in Asian patients. In the initial randomized, double-blind phase, patients with chronic hepatitis C (n = 257) received 12 weeks of treatment with IFN beta-1a, 44 mug subcutaneously 3 times weekly, or a placebo. In the subsequent open-label phase, placebo nonresponders received 24 weeks of treatment with IFN beta-1a plus ribavirin, whereas patients receiving IFN beta-1a monotherapy received an additional 12 weeks of therapy. The primary outcome variable was SVR, which was defined as negative HCV RNA after weeks 24 and 48. A total of 34 of 128 patients (26.6%) receiving IFN beta-1a achieved an SVR versus 0 of 129 patients (0%) receiving the placebo (P < 0.001). In the IFN beta-1a/ribavirin group, 73 of 127 patients (57.5%) achieved an SVR [P < 0.001 versus IFN beta-1a; the adjusted odds ratio was 4.54 (95% confidence interval: 2.53, 8.13)]. In HCV genotype 1 patients, 37 of 80 patients (46.3%) treated with IFN beta-1a/ribavirin achieved an SVR versus 19 of 85 patients (22.4%) treated with IFN beta-1a (P = 0.001). Conclusion: IFN beta-1a produced a clear antiviral effect in Asian patients with chronic HCV infection. The addition of ribavirin to IFN beta-1a significantly increased the proportion of patients who achieved an SVR versus IFN beta-1a monotherapy.     

Reduced healthcare utilization following successful hepatitis C virus treatment in HIV‐co‐infected patients with mild liver disease

New direct‐acting antivirals (DAA) for hepatitis C virus (HCV) infection have achieved high cure rates in many patient groups previously considered difficult‐to‐treat, including those HIV/HCV co‐infected. The high price of these medications is likely to limit access to treatment, at least in the short term. Early treatment priority is likely to be given to those with advanced disease, but a more detailed understanding of the potential benefits in treating those with mild disease is needed. We hypothesized that successful HCV treatment within a co‐infected population with mild liver disease would lead to a reduction in the use and costs of healthcare services in the 5 years following treatment completion. We performed a retrospective cohort study of HIV/HCV‐co‐infected patients without evidence of fibrosis/cirrhosis who received a course of HCV therapy between 2004 and 2013. Detailed analysis of healthcare utilization up to 5 years following treatment for each patient using clinical and electronic records was used to estimate healthcare costs. Sixty‐three patients were investigated, of whom 48 of 63 (76.2%) achieved sustained virological response 12 weeks following completion of therapy (SVR12). Individuals achieving SVR12 incurred lower health utilization costs (£5000 per‐patient) compared to (£10 775 per‐patient) non‐SVR patients in the 5 years after treatment. Healthcare utilization rates and costs in the immediate 5 years following treatment were significantly higher in co‐infected patients with mild disease that failed to achieve SVR12. These data suggest additional value to achieving cure beyond the prevention of complications of disease.     

Factors associated with HCV antiviral treatment uptake among participants of a community‐based HCV programme for marginalized patients

While the majority of cases of hepatitis C virus (HCV) in developed countries occur among illicit drug users, HCV antiviral treatment uptake is poor in this population. Several studies have shown that patients can successfully be treated for HCV in the context of methadone maintenance programmes, but little evidence exists evaluating HCV treatment models for substance users where methadone maintenance is not indicated. This retrospective cohort study involved 129 persons participating in psycho‐educational support groups and integrated, interprofessional, community‐based health services focused on the treatment for HCV among marginalized populations with high rates of crack cocaine use and mental health comorbidities. We sought to identify the factors associated with antiviral treatment uptake. Group participation improved access to health care. While 19% had previously seen an HCV specialist prior to group initiation, 59% saw an HCV specialist during the group. Half of the participants were nonimmune to hepatitis A or B at baseline, and 80% of these patients received immunization through the programme. The programme treated 24 patients with pegylated interferon and ribavirin and achieved a sustained virologic response (SVR) rate of 91% for genotype 2 or 3 and 54% for genotype 1. Stable housing was independently associated with initiation of treatment, and there was a nonsignificant trend towards lower rates of treatment initiation among women. SVR rates for those who had used crack or injection drugs in the month prior to joining the programme did not differ significantly from those who had abstained.     

Treatment of hepatitis C in patients with haemophilia – the Israeli National Hemophilia Center experience

Summary.  Treatment with pegylated interferon (Peg-IFN) and ribavirin, now the standard of care, has been shown to achieve sustained viral response (SVR) in up to 60% of patients with hepatitis C (HCV). Studies of response to this combination in HCV-infected haemophilia patients are scarce. The aim of the study was to report the results and safety of interferon/ribavirin treatment in HCV and HCV-/HIV-infected patients at the Israeli National Hemophilia Center. A retrospective observational cohort study was conducted on haemophilia patients infected with HCV or HCV/HIV. Patients received combination of Peg-IFN and ribavirin. Few were still treated with standard interferon. The primary end-point was sustained viral response (SVR). The secondary end-point was safety, with emphasis on increased bleeding episodes. Some 18/43 (42%) HCV mono-infected haemophilia patients achieved SVR. Relapse occurred in 14 (33%), while 11 patients (25%) were non-responders. SVR was achieved among 17/37 (46%) naïve patients receiving Peg-IFN and ribavirin. Among patients with genotype-1, SVR was achieved in 12/36 (33%) and 11/30 (37%) in the whole group and Peg-IFN treated naïve patients, respectively. In HCV/HIV co-infected patients only 1 patient achieved SVR. Severe anaemia occurred in 14/50 (28%) patients, four received erythropoietin. None maintained stable haemoglobin levels. Two patients had significant bleeding episodes. In our cohort of haemophilia patients, SVR was achieved in a lower than expected rates. A relatively high relapse rate in the HCV mono-infected patients and a very high non-response rate in the HCV/HIV co-infected patients were observed as anticipated. Anaemia was a major side effect and the use of growth factors seemed unrevealing.     

Retrospective analysis of hepatitis C infected patients treated through an integrated care model

AIMTo determine if our health system’s integrated model reflects sustained virologic response (SVR) outcomes similar to those in clinical trial data, maximizes adherence, and averts drug interactions.METHODSSubjects with chronic hepatitis C had their medical records reviewed from November 1^st, 2014 through March 1^st, 2016. Patients eligible for treatment were entered into an integrated care model therapy algorithm. The primary outcome was SVR12 based on intention to treat (ITT) analysis. Inclusion criteria consisted of both treatment naïve and experienced patients over the age of 18 who were at least twelve weeks post-therapy completion with any genotype (GT) or METAVIR score. Secondary outcomes included adherence, adverse events, and number of drug interaction interventions.RESULTSAt the time of analysis, 133 patients had reached twelve weeks post therapy with ITT. In the ITT analysis 70 patients were GT 1a, 26 GT 1b, 23 could not be differentiated between GT 1a or 1b, 8 GT 2, 4 GT 3, and 2 patients with multiple genotypes. The ITT treatment regimens consisted of 97 sofosbuvir (SOF)/ledipasvir (LDV), 8 SOF/LDV and ribavirin (RBV), 7 SOF and Simeprevir (SMV), 6 3D and RBV, 1 3D, 11 SOF and RBV, and 1 SOF, peg interferon alpha, and RBV. The overall SVR12 rate was 93% in the ITT analysis with a total of 6 patients relapsing. In patients with cirrhosis, 89% obtained SVR12. All 33 patients who were previous treatment failures achieved SVR12. Drug-drug interactions were identified in 56.4% of our patient population, 69 of which required interventions made by the pharmacist. The most common side effects were fatigue (41.4%), headache (28.6%), nausea (18.1%), and diarrhea (8.3%). No serious adverse effects were reported.CONCLUSIONDean Health System’s integrated care model successfully managed patients being treated for hepatitis C virus (HCV). The integrated care model demonstrates high SVR rates amongst patients with different levels of fibrosis, genotypes, and HCV treatment history.     

Predicting sustained virological responses in chronic hepatitis C patients treated with peginterferon alfa-2a (40 KD)/ribavirin

BACKGROUND/AIMS: Prediction of sustained virological response (SVR) during treatment would allow clinicians to identify patients most likely to benefit from therapy. METHODS: Retrospective analysis of data from 1121 adults with chronic hepatitis C treated for 48 weeks with peginterferon alfa-2a (40 KD) 180 microg/week plus placebo or ribavirin (1000/1200 mg/day), or interferon alfa-2b 3 MIU three times/week plus ribavirin in a randomized, multinational, study. RESULTS: 67% of patients treated with peginterferon alfa-2a (40 KD)/ribavirin with early virological responses (HCV RNA negative or > or = 2 log10 decrease) at week 12 had SVRs at week 72 (HCV RNA < 50 IU/mL). The negative predictive value (NPV) was 97%. The probability of an SVR increased with the rapidity of HCV RNA suppression. The highest SVR rates were achieved in patients with rapid virological responses at week 4, but the corresponding NPV (74%) is too low for a decision criterion. In patients with early virological responses by week 12, the SVR rate was approximately 20% lower in those who received <80% compared with patients who received > or = 80% of the planned ribavirin dose. CONCLUSIONS: Early, sustained suppression of HCV replication portends an SVR. Cessation of treatment may be contemplated in patients without a > or = 2 log10 reduction in HCV RNA after 12 weeks.     

Dual therapy with the nonstructural protein 5A inhibitor, daclatasvir, and the nonstructural protein 3 protease inhibitor, asunaprevir, in hepatitis C virus genotype 1b-infected null responders

Patients with chronic hepatitis C virus (HCV) infection and previous null response to pegylated interferon (Peg-IFN) and ribavirin (RBV) have limited therapeutic options. HCV genotype 1 is the most common worldwide and the most difficult to treat; genotype 1b is the most common subtype of genotype 1 outside North America. The enhanced antiviral activity achieved by combining two direct-acting antiviral (DAA) agents may improve clinical outcomes. This open-label, phase IIa study included 10 patients with chronic HCV genotype 1b infection and previous null response (<2 log(10) reduction in HCV RNA after 12 weeks) to Peg-IFN and RBV. Patients received dual DAA treatment for 24 weeks with the nonstructural protein 5A replication complex inhibitor, daclatasvir (60 mg once-daily), and the nonstructural protein 3 protease inhibitor, asunaprevir (initially 600 mg twice-daily, then subsequently reduced to 200 mg twice-daily). The primary efficacy endpoint was the proportion of patients with sustained virologic response (SVR) at 12 weeks post-treatment (SVR(12) ). Nine patients completed 24 weeks of treatment; 1 patient discontinued treatment after 2 weeks. In the 9 patients who completed the full course of treatment, HCV RNA was undetectable at week 8 and remained undetectable through the end of treatment; all 9 patients achieved SVR(12) and SVR(24) . HCV RNA also remained undetectable post-treatment in the patient who discontinued after 2 weeks. There was no viral breakthrough. Diarrhea and headache, generally mild, were the most common adverse events; transaminase elevations were reported in 3 patients, but did not result in discontinuation. CONCLUSIONS: Dual therapy with daclatasvir and asunaprevir, without Peg-IFN and RBV, can achieve high SVR rates in difficult-to-treat patients with HCV genotype 1b infection and previous null response to Peg-IFN and RBV.     

Hepatitis C virus testing,liver disease assessment and direct‐acting antiviral treatment uptake and outcomes in a service for people who are homeless in Sydney,Australia: The LiveRLife homelessness study

People who are homeless have increased hepatitis C virus (HCV) infection risk, and are less likely to access primary healthcare. We aimed to evaluate HCV RNA prevalence, liver disease burden, linkage to care and treatment uptake and outcomes among people attending a homelessness service in Sydney. Participants were enrolled in an observational cohort study with recruitment at a homelessness service over eight liver health campaign days. Finger‐stick whole‐blood samples for Xpert® HCV Viral Load and venepuncture blood samples were collected. Participants completed a self‐administered survey and received transient elastography and clinical assessment by a general practitioner or nurse. Clinical follow‐up was recommended 2‐12 weeks after enrolment. For participants initiating direct‐acting antiviral (DAA) therapy, medical records were audited retrospectively and treatment outcome data were collected. Among 202 participants (mean age, 48 years), 82% were male (n = 165), 39% (n = 78) reported ever injecting drugs, of whom 63% (n = 49) injected in the previous month. Overall, 23% (n = 47) had detectable HCV RNA and 6% (n=12) had cirrhosis. HCV RNA prevalence among participants with either injecting or incarceration history was 35% (37/105), compared to 4% (3/73) among participants without these risk factors. Among those with detectable HCV RNA, 23 (49%) commenced therapy, of whom 65% (n = 15) achieved sustained virological response, while the remainder had no available treatment outcome. No participant had documented virological failure. HCV DAA treatment uptake among people attending a homelessness service was encouraging, but innovative models of HCV care are required to improve linkage to care and treatment uptake among this highly marginalized population.     

Optimizing hepatitis C therapy in HIV/hepatitis C virus (HCV) coinfected patients: Analysis of HCV viral kinetics on treatment

INTRODUCTION:

Hepatitis C virus (HCV) infection is potentially curable, but the sustained virological response (SVR) has been shown to be lower in patients coinfected HIV. A single-centre experience treating individuals with HCV and HIV coinfection is reported.

METHODS:

Twenty-one patients who received standard doses of pegylated interferon with weight-based dosing of ribavirin (mean 14.3 mg/kg) were retrospectively reviewed. Qualitative HCV polymerase chain reaction (PCR) was performed prospectively every four weeks if the patient remained HCV PCR positive. All patients with HCV genotype 1 were treated for 48 weeks. Patients with genotype 2 or 3 were treated for 24 weeks and 32 weeks to 36 weeks if their HCV RNA level was undetectable after four weeks (RVR4) or eight weeks (RVR8) of therapy, respectively. If RVR8 was not achieved, the treatment was continued for 48 weeks.

RESULTS:

There were no dropouts or dose reductions within the first 12 weeks of treatment. SVR status was available for 20 patients and adequate serum for viral kinetics analyses was available for 17 patients. Eighty per cent of the patients achieved SVR (50% genotype 1; 100% genotypes 2 and 3). The week 8 viral load remained elevated for all genotype 1 nonresponders.

DISCUSSION:

High effectiveness rates were seen, particularly in patients with HCV genotype 2 and 3 who were treated for shorter durations. HCV viral loads after eight weeks of therapy helped distinguish patients with HCV genotype 1 who would respond to therapy.     

Long-term follow-up of patients with chronic hepatitis C with sustained virologic response to interferon

Background and aimThe durability of the sustained virologic response (SVR) in patients with chronic hepatitis C after treatment and the ideal follow-up time for these patients remains undefined. The objective of the study was to evaluate the durability of the virologic response in patients with chronic hepatitis C followed up for at least 12 months after SVR at HCFMRP-USP.Methods: The study was conducted on 174 patients with chronic hepatitis C treated with different antiviral regimens who had achieved SVR. Qualitative serum HCV-RNA was determined by the commercial kit (COBAS AMPLICOR HCV, v2.0).ResultsThere was predominance of male (73%) with a mean age of 45.6 ± 10 years. Liver cirrhosis was present in 16.1% of the study subjects. Mean follow-up time after SVR was 47 months (12-156 months). Twenty-two patients received monotherapy with interferon; 94 received interferon plus ribavirin, and 58 received pegylated interferon plus ribavirin. A total of 134 patients (77.0%) received one treatment course, 29 (16.7%) received two courses, and 11 (6.3%) received three courses. The distribution of HCV genotypes was: genotype 1 (40.2%), genotype 3 (40.8%) and genotype 2 (10.3%). Genotype was undetermined in 8.7% of cases. None of the 174 patients had recurrence of HCV infection. Two cirrhotic patients developed hepatocellular carcinoma (HCC) during follow-up.ConclusionsAmong patients with SVR there was no recurrence of HCV infection or evidence of liver disease progression in any patient followed up for a mean of 47 months after SVR, except for patients with advanced hepatic disease before treatment, who may develop HCC despite SVR. Therefore, one can assume that SVR is associated with long term good prognosis.     

Defining the hepatitis C cure cascade in an Urban health system using the electronic health record

Hepatitis C virus (HCV) infection is a public health threat. The electronic health record (EHR) can be used to monitor patients along the HCV cure cascade and highlight opportunities for interventions to improve cascade outcomes. We developed an HCV patient registry using data from Grady Health System's (GHS) EHR and performed a cross‐sectional analysis of 72 745 GHS patients who received anti‐HCV testing from 2004 to 2016. We created a testing cascade: (1) anti‐HCV reactive, (2) HCV RNA tested and (3) HCV RNA detectable; and a cure cascade: (1) HCV RNA detectable, (2) engaged in care, (3) treatment prescribed, (4) sustained virologic response (SVR) tested and (5) SVR documented. A total of 9893 (14%) had reactive anti‐HCV tests of 72 745 patients tested, 5109 (52%) of these had HCV RNA tested, and 4224 (43%) were HCV RNA detectable. A total of 2738 (65%) of 4224 with detectable RNA were engaged in care, 909 (22%) were prescribed antiviral therapy, and 354 (8%) achieved SVR. Factors associated with HCV treatment included cirrhosis, tobacco use, depression, diabetes, obesity, alcohol use, male gender, black race and Medicare insurance. Uninsured patients were significantly less likely to be prescribed HCV treatment. In conclusion, using EHR data, we identified high anti‐HCV prevalence and noted gaps in HCV RNA testing, linkage to care and treatment. The EHR can be used to evaluate the effectiveness of targeted interventions to overcome these gaps.     

Sofosbuvir and ledipasvir improve patient‐reported outcomes in patients co‐infected with hepatitis C and human immunodeficiency virus

A fixed‐dose combination of ledipasvir and sofosbuvir (LDV/SOF) has been approved for treatment of HCV patients. We assessed the effect of LDV/SOF on patient‐reported outcomes (PROs) in HIV–HCV‐co‐infected patients. Patient‐reported outcomes data from HIV–HCV‐co‐infected patients who were treated with LDV/SOF for 12 weeks were collected as a part of a clinical trial (ION‐4). Historical controls were HIV–HCV‐co‐infected patients treated with SOF and ribavirin (RBV) in PHOTON‐1. We included 335 HIV–HCV‐co‐infected patients (SVR‐12 in HCV genotype 1 was 96%) who received LDV/SOF, while 223 patients (SVR‐12 in HCV genotype 1 was 76.3%) received SOF/RBV. During treatment, patients receiving LDV/SOF showed improvement in all of their PRO scores (+6.0% in activity/energy of CLDQ‐HCV, +5.0% in fatigue score of FACIT‐F, +6.8% in physical component of SF‐36; all P < 0.0001) while those receiving SOF+RBV showed moderate decline in some of their PRO scores (?4.8% in physical functioning of SF‐36, ?4.4% in fatigue score of FACIT‐F, both P < 0.001). Patients who achieved sustained virologic response with LDV/SOF also showed improvement of PROs (average +5.1%) while those treated with SOF/RBV showed less or no improvement (average +1.4%). In a multivariate analysis, in addition to depression and fatigue, receiving SOF+RBV (vs LDV/SOF) was independently associated with more PRO impairment during treatment (beta ?6.1 to ?12.1%, P < 0.001). Hence, HIV–HCV patients treated with LDV/SOF show significant improvement of their health‐related quality of life and other patient‐reported outcomes during treatment and after treatment cessation.     

Open‐label study of faldaprevir plus peginterferon and ribavirin in hepatitis C virus genotype 1‐infected patients who failed placebo plus peginterferon and ribavirin

Faldaprevir, a hepatitis C virus (HCV) NS3/4A protease inhibitor, was evaluated in HCV genotype 1‐infected patients who failed peginterferon and ribavirin (PegIFN/RBV) treatment during one of three prior faldaprevir trials. Patients who received placebo plus PegIFN/RBV and had virological failure during a prior trial were enrolled and treated in two cohorts: prior relapsers (n = 43) and prior nonresponders (null responders, partial responders and patients with breakthrough; n = 75). Both cohorts received faldaprevir 240 mg once daily plus PegIFN/RBV for 24 weeks. Prior relapsers with early treatment success (ETS; HCV RNA <25 IU/mL detectable or undetectable at week 4 and <25 IU/mL undetectable at week 8) stopped treatment at week 24. Others received PegIFN/RBV through week 48. The primary efficacy endpoint was sustained virological response (HCV RNA <25 IU/mL undetectable) 12 weeks post treatment (SVR12). More prior nonresponders than prior relapsers had baseline HCV RNA ≥800 000 IU/mL (80% vs 58%) and a non‐CC IL28B genotype (91% vs 70%). Rates of SVR12 (95% CI) were 95.3% (89.1, 100.0) among prior relapsers and 54.7% (43.4, 65.9) among prior nonresponders; corresponding ETS rates were 97.7% and 65.3%. Adverse events led to faldaprevir discontinuations in 3% of patients. The most common Division of AIDS Grade ≥2 adverse events were anaemia (13%), nausea (10%) and hyperbilirubinaemia (9%). In conclusion, faldaprevir plus PegIFN/RBV achieved clinically meaningful SVR12 rates in patients who failed PegIFN/RBV in a prior trial, with response rates higher among prior relapsers than among prior nonresponders. The adverse event profile was consistent with the known safety profile of faldaprevir.
