[PMID: 38880700 DOI: 10.1016/j.drugpo.2024.104469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 05/14/2024] [Accepted: 05/18/2024] [Indexed: 06/18/2024]
Abstract
INTRODUCTION The introduction of new direct-acting antivirals for hepatitis C virus (HCV) infection, has enabled the formulation of a HCV elimination strategy led by the World Health Organisation (WHO). Guidelines for elimination of HCV target a reduction in incidence, but this is difficult to measure and needs estimating. METHODS Serial cross-sectional bio-behavioural sero-surveys provide information on an individual's infection status and duration of exposure and how these change over time. These data can be used to estimate the rate of first infection through appropriate statistical models. This study utilised updated HCV seroprevalence information from the Unlinked Anonymous Monitoring survey, an annual survey of England, Wales and Northern Ireland monitoring the prevalence of blood borne viruses in people who inject drugs. Flexible parametric and semiparametric approaches, including fractional polynomials and splines, for estimating incidence rates by exposure time and survey year were implemented and compared. RESULTS Incidence rates were shown to peak in those recently initiating injecting drug use at approximately 0.20 infections per person-year followed by a rapid reduction in the subsequent few years of injecting to approximately 0.05 infections per person-year. There was evidence of a rise in incidence rates for recent initiates between 2011 and 2020 from 0.17 infections per person-year (95 % CI, 0.16-0.19) to 0.26 infections per person-year (0.23-0.30). In those injecting for longer durations, incidence rates were stable over time. CONCLUSIONS Fractional polynomials provided an adequate fit with relatively few parameters, but splines may be preferable to ensure flexibility, in particular, to detect short-term changes in the rate of first infection over time that may be a result of treatment effects. Although chronic HCV prevalence has declined with treatment scale up over 2016-2020, there is no evidence yet of a corresponding fall in the rate of first infection. Seroprevalence and risk behaviour data can be used to estimate and monitor HCV incidence, providing insight into progress towards WHO defined elimination of HCV.

Patients with severe mental illness and hepatitis C virus infection benefit from new pangenotypic direct-acting antivirals: Results of a literature review. GASTROENTEROLOGIA Y HEPATOLOGIA 2023; 46:382-396.

Abstract
INTRODUCTION Hepatitis C virus (HCV) infection is a global health problem that can results in cirrhosis, hepatocellular carcinoma and even death. HCV infection is 3-20-fold more prevalent among patients with versus without severe mental illness (SMI), such as major depressive disorder, personality disorder, bipolar disorder and schizophrenia. Treatment options for HCV were formerly based on pegylated interferon alpha, which is associated with neuropsychiatric adverse events, and this contributed to the exclusion of patients with SMI from HCV treatment, elimination programmes, and clinical trials. Moreover, the assumption of poor adherence, scant access to healthcare and the stigma and vulnerability of this population emerged as barriers and contributed to the low rates of treatment and efficacy. METHODS This paper reviews the literature published between December 2010 and December 2020 exploring the epidemiology of HCV in patients with SMI, and vice versa, the effect of HCV infection, barriers to the management of illness in these patients, and benefits of new therapeutic options with pangenotypic direct antiviral agents (DAAs). RESULTS The approval of DAAs has changed the paradigm of HCV infection treatment. DAAs have proven to be an equally efficacious and safe option that improves quality of life (QoL) in patients SMI. CONCLUSIONS Knowledge of the consequences of the HCV infection and the benefits of treatment with new pangenotypic DAAs among psychiatrists can increase screening, referral and treatment of HCV infection in patients with SMI.

Singlet oxygen and radical-mediated mechanisms in the oxidative cellular damage photosensitized by the protease inhibitor simeprevir. Free Radic Biol Med 2023; 194:42-51.

Abstract
Hepatitis C, a liver inflammation caused by the hepatitis C virus (HCV), is treated with antiviral drugs. In this context, simeprevir (SIM) is an NS3/4A protease inhibitor used in HCV genotypes 1 and 4. It is orally administered and achieves high virological cure rates. Among adverse reactions associated with SIM treatment, photosensitivity reactions have been reported. In the present work, it is clearly shown that SIM is markedly phototoxic, according to the in vitro NRU assay using BALB/c 3T3 mouse fibroblast. This result sheds light on the nature of the photosensitivity reactions induced by SIM in HCV patients, suggesting that porphyrin elevation in patients treated with SIM may not be the only mechanism responsible for SIM-associated photosensitivity. Moreover, lipid photoperoxidation and protein photooxidation assays, using human skin fibroblasts (FSK) and human serum albumin (HSA), respectively, reveal the capability of this drug to promote photodamage to cellular membranes. Also, DNA photo lesions induced by SIM are noticed through comet assay in FSK cells. Photochemical and photobiological studies on the mechanism of SIM-mediated photodamage to biomolecules indicate that the key transient species generated upon SIM irradiation is the triplet excited state. This species is efficiently quenched by oxygen giving rise to singlet oxygen, which is responsible for the oxidation of lipids and DNA (Type II mechanism). In the presence of HSA, the photobehavior is dominated by binding to site 3 of the protein, to give a stable SIM@HSA complex. Inside the complex, quenching of the triplet excited state is less efficient, which results in a longer triplet lifetime and in a decreased singlet oxygen formation. Hence, SIM-mediated photooxidation of the protein is better explained through a radical (Type I) mechanism.

AN ACAD BRAS CIENC 2021; 93:e20200632. [PMID: 34586319 DOI: 10.1590/0001-3765202120200632] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Accepted: 07/03/2020] [Indexed: 11/22/2022] Open
Abstract
Direct-acting antivirals have revolutionized the treatment of chronic hepatitis C. Sofosbuvir and simeprevir are prescribed worldwide. However, there is a scarcity of information regarding their genotoxicity. Therefore, the present study assessed the cytotoxic and genotoxic effects of sofosbuvir and simeprevir, alone and combined with ribavirin. HepG2 cells were analyzed using the in vitro cytokinesis-block micronucleus cytome assay. Cells were treated for 24 h with sofosbuvir (0.011-1.511 mM), simeprevir (0.156-5.0 µM), and their combinations with ribavirin (0.250-4.0 mM). No significant differences were observed in the nuclear division cytotoxicity index, reflecting the absence of cytotoxic effects associated to sofosbuvir. However, the highest concentration of simeprevir showed a significant difference for the nuclear division cytotoxicity index. Moreover, significant results were observed for nuclear division cytotoxicity index in two combinations of sofosbuvir plus ribavirin and only in the highest combination of simeprevir plus ribavirin. Additionally, our results showed that sofosbuvir did not increase the frequency of chromosomal damage, but simeprevir significantly increased the frequency of micronuclei at the highest concentrations. The combination index demonstrated that both sofosbuvir and simeprevir produced antagonism to the genotoxic effects of ribavirin. In conclusion, our results showed that simeprevir, but not sofosbuvir, has genotoxic effects in HepG2 cells.

Abstract
(1) Background: Treatment of hepatitis C virus (HCV) infections with direct-acting antivirals (DAA) has demonstrated high efficacy and an excellent safety profile. The cured patients showed a sustained virological response and improved liver function, but also a continued risk of hepatocellular carcinoma (HCC) during the 2-3 years of follow-up after treatment; (2) Methods: A total of 192 patients out of 209 of the primary AMBER study were analyzed five years after treatment with ombitasvir/paritaprevir/ritonavir with or without dasabuvir and with or without ribavirin. Results: We confirmed that HCV clearance after DAA treatment is stable regardless of baseline liver fibrosis. We found that sustained virologic response is associated with a gradual but significant reduction in liver stiffness over 5 years. Liver function improved during the first 2 years of follow-up and remained stable thereafter. The risk of death due to HCC as well as death due to HCV persists through 5 years of follow-up after successful DAA treatment. However, in non-cirrhotic patients, it appears to clear up 3 years after treatment; (3) Conclusions: Monitoring for more than 5 years after curing HCV infection is necessary to assess the long-term risk of possible development of HCC, especially in patients with cirrhosis of the liver.

Abstract
Objective The study aimed to assess the safety profile of Direct Acting Anti-Viral's (DAAs) among patients with chronic Hepatitis C Virus (HCV). Methods This multicenter, analytical cross-sectional study was conducted in six gastroenterology and Hepatology centers including Liver Center Faisalabad, Allama Iqbal Medical Institute and Liver Center DHQ Hospital Sialkot, Isra Hospital Hyderabad, Allied Hospital Faisalabad and Rehman Medical Institute Peshawar, between May 2018 and May 2019. The data regarding patient demographics, treatment plan and the frequency of Adverse Events (AEs), and their severity was collected using a pre-designed questionnaire and analyzed through SPSS version 20.0. Results A total of 511 HCV patients were enrolled, with an overall male majority. Around 66.3% patients experienced a total of 419 AEs, out of which 61 events were suspected from DAAs while remaining 317 events were associated with Ribavirin. Pyrexia (24.6%) and fatigue (14.8%) were the most commonly reported AEs among patients receiving DAAs. Factors such as Ribavirin-based treatments and the presence of Cirrhosis were more likely to promote AEs occurrence OR [95%CI] i.e. 5.2(2.3-9.1) and 1.9(1.1-3.1) respectively (p < 0.05). Conclusion It is concluded from the study results that DAAs have displayed promising outcomes due to the minimal and minor AEs reported.

Abstract
BACKGROUND/AIMS Hepatitis C virus (HCV) has been identified in tubular epithelial cells of infected patients; however, the presence of tubular dysfunction, which is a risk factor for chronic kidney disease (CKD), has never been examined in vivo. The present prospective longitudinal study aimed to estimate the prevalence of tubular dysfunction alone or with glomerular damage and its evolution after HCV clearance in cirrhotic patients. METHODS One hundred and thirty-five consecutive Child-Pugh A cirrhotic patients were evaluated before antiviral treatment and 6 months after the end of therapy. Tubular dysfunction was evaluated by urinary alpha1-microglobulin to creatinine ratio (α1-MCR), and glomerular damage was assessed by urinary albumin to creatinine ratio (ACR). RESULTS Almost all the patients (93.3%) showed a normal or mildly decreased e-GFR (KDIGO-G1/G2-categories). Tubular dysfunction was found in 23.7% (32/135) of patients, co-occurring with glomerular damage in 37.5% (12/32) of cases, while glomerular damage was found in 16.3% (22/135) of patients. In multiple logistic regression, glomerular damage and the concomitant presence of diabetes and hypertension were the only predictors significantly associated with tubular dysfunction. After HCV clearance, patients experienced a significant reduction of α1-MCR levels (21.0 vs 10.5 μg/mg, P = .009) and tubular dysfunction resolved in 57.1% of subjects. CONCLUSIONS Tubular dysfunction is an unrecognized feature of HCV-related kidney disease in cirrhotic patients and its presence should be primarily investigated in subjects with glomerular damage, diabetes and hypertension, despite normal e-GFR. Tubular dysfunction resolves in the majority of cases after HCV clearance; however, it may persist after antiviral treatment and further studies should evaluate its long-term impact on kidney function.

Abstract
Introduction The world over, hepatitis C virus (HCV) engenders the risk of developing chronic hepatitis, cirrhosis and hepatocellular carcinoma (HCC). It has many extrahepatic manifestations, among which diabetes and metabolic syndrome (MetS) has been increasingly recognized and has become an active research field. The current study aimed to ascertain the frequency of MetS in chronic hepatitis C patients and to curb its long-term adverse outcomes. Methods In our cross-sectional analysis, a total of 331 subjects diagnosed with chronic HCV were registered from June 2017 to November 2018 in two tertiary care hospitals of Karachi, Pakistan. Metabolic syndrome (MetS) was delineated following the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III). Categorical variables were compared by using the Chi-square test, and a significant P value was at the value of < 0.05. Results We found that adults of 40 - 49 years of age were the worst sufferers of hepatitis C. Out of the total 331 patients of hepatitis C, 97 (29.3%) cases were suffering from metabolic syndrome. Conclusion Prevalence of MetS is substantial among HCV-infected individuals Therefore estimation of MetS in individuals with HCV infection is imperative and patients should be educated for lifestyle modification, diet, and weight control. However, we cannot generalized the results of our study as it was done in some tertiary care centres, so additional surveys are warranted to know the actual prevalence of MetS in our entire population.

Abstract
Hepatitis virus infection is a major public health problem worldwide. Currently, Brazil has almost 700,000 cases. The Brazilian Unified Health System (SUS) provides therapeutic regimens for people infected with hepatitis C virus (HCV). We determined the clinical, laboratory, epidemiologic, and geospatial characteristics of patients infected with HCV treated with second-generation direct-action antivirals (DAAs) in a hospital reference center in São Paulo state, Brazil, using data from file records. A map was constructed using a geographic information system. From 2015 to 2018, 197 individuals received second-generation DAAs (mean age, 57.68 ± 1.36 years; interquartile range, 56.22–59.14 years; 58.9% male; 41.1% female). Genotypes 1a and 1b accounted for 75.7% of cases and the prevalent therapeutic regimen was sofosbuvir/simeprevir. Sustained viral response accounted for 98.9% and the METAVIR score F3/F4 for 50.8%. Increased alanine transferase was significantly correlated with an increase in α-fetoproteins (p = 0.01), and severe necro-inflammatory activity (p = 0.001). Associated comorbidities were found in 71.6%, mainly coronary artery and gastrointestinal disorders. The cumulative incidence in the region was 2.6 per 10,000 inhabitants. Our data highlight the role of reference hospitals in Brazil’s public health system in the treatment of HCV. Low incidence rates demonstrated the fragility of municipalities in the active search for patients.

Direct antiviral therapy for treatment of hepatitis C: A real-world study from Brazil. Ann Hepatol 2020; 18:849-854. [PMID: 31537509 DOI: 10.1016/j.aohep.2019.08.001] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2019] [Revised: 07/31/2019] [Accepted: 08/06/2019] [Indexed: 02/04/2023]
Abstract
INTRODUCTION AND OBJECTIVES Direct antiviral agents (DAAs) including sofosbuvir (SOF), daclatasvir (DCV), simeprevir (SIM) and ombitasvir, paritaprevir and dasabuvir were introduced 2015 in Brazil for treatment of hepatitis C virus (HCV) infection. The aims of this study were to assess effectiveness and safety of HCV treatment with DAA in real-life world in a highly admixed population from Brazil. MATERIALS AND METHODS All Brazilian reference centers for HCV treatment were invited to take part in a web-based registry, prospectively conducted by the Brazilian Society of Hepatology, to assess outcomes of HCV treatment in Brazil with DAAs. Data to be collected included demographics, disease severity and comorbidities, genotype (GT), viral load, DAA regimens, treatment side effects and sustained virological response (SVR). RESULTS 3939 patients (60% males, mean age 58±10 years) throughout the country were evaluated. Most had advanced fibrosis or cirrhosis, GT1 and were treated with SOF/DCV or SOF/SIM. Overall SVR rates were higher than 95%. Subjects with decompensated cirrhosis, GT2 and GT3 have lower SVR rates of 85%, 90% and 91%, respectively. Cirrhosis and decompensated cirrhosis in GT1 and male sex and decompensated cirrhosis in GT3 were significantly associated with no SVR. Adverse events (AD) and serious AD occurred in 18% and 5% of those subjects, respectively, but less than 1% of patients required treatment discontinuation. CONCLUSION SOF-based DAA regimens are effective and safe in the heterogeneous highly admixed Brazilian population and could remain an option for HCV treatment at least in low-income countries.

Abstract
OBJECTIVES To introduce and discuss the cost and effectiveness of using sofosbuvir, daclatasvir, and simeprevir antivirals, in combination or not with peginterferon alfa and ribavirin, for the treatment of hepatitis C, as based on real-world data. METHODS We analyzed the treatment and outcomes of 253 patients from a retrospective cohort held in a specialized assistance service in the municipality of Porto Alegre, Brazil. Regarding costs, we considered only the direct costs of the antiviral medications per unit (pills), according to the financial receipts of the public procurements. We calculated the total cost of treatment per individual and the cost per cure expressed in sustained virologic response (SVR). RESULTS Most patients (66.8%) were carriers of the genotype 1 of hepatitis, and 92.9% reached the SVR. The average cost of the treatment for genotype-1 patients was $5,862.31 USD per patient and $6,310.34 for the cure; for genotype-3 patients, on the other hand, the cost was $5,144.27 per patient and $5,974.76 for the cure. The drugs purchasing cost was around 40% less than was estimated for the process of incorporating them into the public health system. CONCLUSION The results indicated that good rates of effectiveness were achieved with different combinations of the medicines. The costs of the medicines were still deemed too high for the Brazilian reality, however. Therefore the results contribute to support the formulation and review of public policies based on strong evidence and on real-world data for the treatment of hepatitis C.

Abstract
Objective Toward the limited real-world data concerning the treatment response to brand direct-acting antiviral agents (DAAs) therapy, we proposed to evaluate the efficacy and safety of DAAs for the treatment of chronic hepatitis C virus (HCV) in mainland China. Methods In this retrospective, single-center, cohort study, all HCV-infected adult patients treated with brand DAA drugs covered by Tianjin local health insurance (Apr 2018–Sept 2019) and responding to other specific inclusion criteria were recruited. The five available DAA regimens included sofosbuvir + ribavirin (SOF + RBV), elbasvir/grazoprevir (EBR/GZR), ombitasvir/paritaprevir/ritonavir/dasabuvir (OBV/PTV/r/DSV) ± RBV, daclatasvir + asunaprevir (DCV + ASV), and SOF + DCV ± RBV. Demographic, virologic, clinical, and adverse effects data obtained during and after DAAs treatment were collected. We evaluated the rate of sustained virological response at 12 weeks post-treatment (SVR12), the incidence of adverse effects, and assessed the factors associated with SVR12. Results Four hundred ninety-four patients finished the treatment and completed the 12-week post-treatment follow-up. The overall SVR12 rate was estimated at 96.96%. SVR rates greater than 95% were achieved in most of the HCV genotypes with the exception of GT1a (0%), GT3a (93.33%), and GT3b (88.24%). SVR12 for patients treated with DCV + ASV, EBR/GZR, OBV/PTV/r/DSV ± RBV, SOF + DCV ± RBV, and SOF + RBV for 12 or 24 weeks was 86.67%, 100%, 98.11%, 97.56%, and 95.06%, respectively. Subjects with compensated cirrhosis (92.73%) and prior treatment experience (77.78%) had significantly lower SVR rates when compared to chronic hepatitis C (98.15%) and treatment-naive (97.69%) groups. In Tianjin, the available DAA regimens were generally well-tolerated, and not a single serious adverse event was reported. Conclusion In this large real-life single-center HCV cohort from China, oral DAAs were highly effective and well-tolerated. Further and larger-scale studies are needed to evaluate their clinical safety and efficacy.

REVISTA BRASILEIRA DE PSIQUIATRIA (SAO PAULO, BRAZIL : 1999) 2020; 42:72-76. [PMID: 31314868 PMCID: PMC6986477 DOI: 10.1590/1516-4446-2018-0336] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Accepted: 04/18/2019] [Indexed: 01/19/2023]
Abstract
OBJECTIVE Depression has been associated with hepatitis C, as well as with its treatment with proinflammatory cytokines (i.e., interferon). The new direct-acting antiviral agents (DAAs) have minimal adverse effects and high potency, with a direct inhibitory effect on non-structural viral proteins. We studied the incidence and associated factors of depression in a real-life prospective cohort of chronic hepatitis C patients treated with the new DAAs. METHODS The sample was recruited from a cohort of 91 patients with hepatitis C, of both sexes, with advanced level of fibrosis and no HIV coinfection, consecutively enrolled during a 6-month period for DAA treatment; those euthymic at baseline (n=54) were selected. All were evaluated through the depression module of the Patient Health Questionnaire (PHQ-9-DSM-IV), at three time points: baseline, 4 weeks, and end-of-treatment. RESULTS The cumulative incidence (95%CI) of major depression and any depressive disorder during DAA treatment was 13% (6.4-24.4) and 46.3% (33.7-59.4), respectively. No differences were observed between those patients with and without cirrhosis or ribavirin treatment (p > 0.05). Risk factors for incident major depression during DAA treatment included family depression (relative risk 9.1 [1.62-51.1]), substance use disorder (11.0 [1.7-73.5]), and baseline PHQ-9 score (2.1 [1.1-3.1]). CONCLUSIONS The findings of this study highlight the importance of screening for new depression among patients receiving new DAAs, and identify potential associated risk factors.

Abstract
Objective The influence of interferon (IFN)-free direct-acting antiviral (DAA) on hepatocellular carcinoma (HCC) recurrence remains unclear. Previous retrospective analyses revealed that the time interval between HCC curative treatment and IFN-free DAA induction is the critical factor affecting HCC recurrence. Thus, this study aimed to examine the influence of DAA therapy on HCC recurrence considering this interval. Methods Factors contributing to HCC recurrence were retrospectively analyzed using a landmark time analysis and time-dependent extended Cox proportional hazards model. Patients After screening 620 patients who were diagnosed with primary HCC from January 2001 to December 2016, 76 patients with early-stage (primary and solitary) disease who received curative treatment and were positive for serum hepatitis C virus RNA were included. Results HCC recurrence was observed in 8 of 17 (47.1%) patients who had received IFN-free DAA therapy and 45 of 59 (76.3%) who had not. No significant difference was seen between the IFN-free DAA (-) and IFN-free DAA (+) groups in the landmark time and time-dependent Cox proportional hazards model analyses. However, IFN-free DAA therapy tended to decrease the HCC recurrence rate after curative treatment for primary HCC in patients with chronic hepatitis. In addition, IFN-free DAA therapy tended to decrease the second HCC recurrence rate after treatment for the first HCC recurrence. Conclusion Our results, with a consideration of the time interval between HCC curative treatment and IFN-free DAA induction, showed that IFN-free DAA therapy was not associated with early-stage HCC recurrence after curative treatment.

Abstract
BACKGROUND According to current recommendations diagnosis and management of HCV infection need detection and quantification of nucleic acids. In the era of direct-acting antivirals (DAA) it is essential to develop an inexpensive and simple method replacing polymerase chain reaction. Since there is no available data on HCV core antigen (HCVcAg) versus HCV RNA kinetics in the early phase of treatment with DAA, we carried out this study to evaluate the possible application of HCVcAg quantitative measurement for management of HCV infection. METHODS 33 patients with HCV infection were enrolled and treated with either ombitasvir/paritaprevir/ritonavir ± dasabuvir ± ribavirin (OBV/PRV/r±DSV±RBV) or ledipasvir/sofosbuvir (LDV/SOF). Samples for quantitative HCV RNA and HCVcAg measurement were collected at the baseline, after 1, 7, 28 days and at the end of treatment, and then after 12 and 24 weeks of post-treatment follow-up. RESULTS There was positive correlation between HCVcAg and HCV RNA levels at the baseline and after 1 day of treatment. Mean HCVcAg concentration declined faster than HCV RNA levels during the treatment phase. At week 4 HCV RNA was undetectable in 24, whereas HCVcAg in 28 patients. At the end of treatment and after 12 weeks of follow-up all patients were undetectable for both HCV RNA and HCVcAg. CONCLUSIONS HCVcAg concentration and its early on-treatment testing can predict virological response. Simple testing procedures and significantly lower cost compared to HCV RNA testing support possible replacement of the viral load measurement in management of the majority of HCV-infected patients.

Abstract
BACKGROUND AND AIMS Limited data are available on the effectiveness and tolerability of direct-acting antivirals (DAAs) therapies in the real world for HCV-infected patients with comorbidities. This study aimed to describe the effectiveness of OBV/PTV/r ± DSV (3D/2D regimen) with or without ribavirin (RBV) in HCV or HCV/HIV co-infected patients with GT1/GT4 and CKD (IIIb-V stages), including those under hemodialysis and peritoneal dialysis in routine clinical practice in Spain in 2015. MATERIAL AND METHODS Non-interventional, retrospective, multicenter data collection study in 31 Spanish sites. Socio-demographic, clinical variables, study treatment characteristics, effectiveness and tolerability data were collected from medical records. RESULTS Data from 135 patients with a mean age (SD) of 58.3 (11.4) years were analyzed: 92.6% GT1 (81.6% GT1b and 17.6% GT1a) and 7.4% GT4, 14 (10.4%) HIV/HCV co-infected, 19.0% with fibrosis F3 and 28.1% F4 by FibroScan®, 52.6% were previously treated with pegIFN and RBV. 11.1%, 14.8% and 74.1% of patients had CKD stage IIIb, IV and V respectively. 68.9% of patients were on hemodialysis; 8.9% on peritoneal dialysis and 38.5% had history of renal transplant. A total of 125 (96.2%) of 135 patients were treated with 3D, 10 (7.4%) with 2D and 30.4% received RBV. The overall intention-to-treat (ITT) sustained virologic response at week 12 (SVR12) was 92.6% (125/135) and the overall modified-ITT (mITT) SVR12 was 99.2% (125/126). The SVR12 rates (ITT) per sub-groups were: HCV mono-infected (91.7%), HCV/HIV co-infected (100%), GT1 (92.0%), GT4 (100%), CKD stage IIIb (86.7%), stage IV (95%) and stage V (93%). Among the 10 non-SVR there was only 1 virologic failure (0.7%); 4 patients had missing data due lost to follow up (3.0%) and 5 patients discontinued 3D/2D regimen (3.7%): 4 due to severe adverse events (including 3 deaths) and 1 patient´s decision. CONCLUSIONS These results have shown that 3D/2D regimens are effective and tolerable in patients with advanced CKD including those in dialysis with GT 1 or 4 chronic HCV mono-infection and HIV/HCV coinfection in a real-life cohort. The overall SVR12 rates were 92.6% (ITT) and 99.2% (mITT) without clinically relevant changes in eGFR until 12 weeks post-treatment. These results are consistent with those reported in clinical trials.

Abstract
U.S. guidelines recommend that patients coinfected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) be prioritized for HCV treatment with direct-acting antiviral agents (DAAs), but the high cost of DAAs may contribute to disparities in treatment uptake and outcomes. We evaluated DAA initiation and effectiveness in HIV/HCV-coinfected patients in a U.S.-based healthcare system during October 2014-December 2017. Of 462 HIV/HCV-coinfected patients, 276 initiated DAAs (70% cumulative proportion treated over three years). Lower likelihood of DAA initiation was observed among patients with Medicare (government-sponsored insurance) versus commercial insurance (adjusted rate ratio [aRR] = 0.62, 95% CI = 0.46-0.84), patients with drug abuse diagnoses (aRR = 0.72, 95% CI = 0.54-0.97), patients with CD4 cell count <200 cells/µl versus ≥500 (aRR = 0.45, 95% CI = 0.23-0.91), and patients without prior HCV treatment (aRR = 0.68, 95% CI = 0.48-0.97). There were no significant differences in DAA initiation by age, gender, race/ethnicity, socioeconomic status, HIV transmission risk, alcohol use, smoking, fibrosis level, HIV RNA levels, antiretroviral therapy use, hepatitis B infection, or number of outpatient visits. Ninety-five percent of patients achieved sustained virologic response (SVR). We found little evidence of sociodemographic disparities in DAA initiation among HIV/HCV-coinfected patients, and SVR rates were high. Efforts are needed to increase DAA uptake among coinfected Medicare enrollees, patients with drug abuse diagnoses, patients with low CD4 cell count, and patients receiving first-time HCV treatment.

Abstract
BACKGROUND AND AIMS According to clinical trials, the treatment of patients with chronic hepatitis C (CHC) with second-generation direct acting antiviral agents (DAAs) is highly efficient and well tolerated. The goal of this study was to investigate the effectiveness and safety of various combinations of these drugs during their first 2 years of use in the real-world practice of French general hospitals. METHODS Data from patients treated with all-oral DAAs in 24 French non-academic hospital centers from March 1, 2014 to January 1, 2016, were prospectively recorded. The sustained virological response 12-24 weeks after treatment (SVR 12-24) was estimated and severe adverse events (SAE) were evaluated and their predictive factors were determined using logistic regression. RESULTS Data from 1123 patients were analyzed. The population was 69% genotype (G) 1, 13% G3, 11.5% G4, 5% G2, 49% with cirrhosis and 55% treatment-experienced. The treatment regimens were sofosbuvir/ledipasvir (38%), sofosbuvir/daclatasvir (32%), sofosbuvir/simeprevir (17%), ombitasvir+paritaprevir+ritonavir (5%) (with dasabuvir 3.5%), and sofosbuvir/ribavirin (8%). Ribavirin was given to 24% of patients. The SVR 12-24 was 91.0% (95% CI: 89.2-92.5%). Sofosbuvir-ribavirin was less effective than other regimens. The independent predictors of SVR 12-24 by logistic regression were body weight, albumin, previous hepatocellular carcinoma and treatment regimen (sofosbuvir/ribavirin vs. others). Sixty-four severe adverse events (SAE) were observed in 59 [5.6%] patients, and were independently predicted by cirrhosis and baseline hemoglobin. Serum creatinine increased during treatment (mean 8.5%, [P<10-5]), satisfying criteria for acute kidney injury in 62 patients (7.3%). Patient-reported overall tolerance was excellent, and patient-reported fatigue decreased during and after treatment. CONCLUSIONS Second generation DAAs combinations are as effective and well tolerated in a « real-world » population as in clinical trials. Further studies are needed on renal tolerance.

Abstract
Novel direct-acting antivirals (DAAs) are now the standard of care for the management of hepatitis C virus (HCV) infection. Branded DAAs are associated with high sustained virological response at 12 weeks post-completion of therapy (SVR12), but are costly. We aimed to assess the efficacy of generic oral DAAs in a real-life clinical scenario. Consecutive patients with known HCV infection who were treated with generic-oral DAA regimens (May 2015 to January 2017) were included. Demographic details, prior therapy and SVR12 were documented. Four hundred and ninety patients (mean age: 38.9 ± 12.7 years) were treated with generic DAAs in the study time period. Their clinical presentations included chronic hepatitis (CHC) in 339 (69.2%) of cases, compensated cirrhosis in 120 (24.48%) cases and decompensated cirrhosis in 31 (6.32%) cases. Genotype 3 was most common (n = 372, 75.9%) followed by genotype 1 (n = 97, 19.8%). Treatment naïve and treatment-experienced (defined as having previous treatment with peginterferon and ribavirin) were 432 (88.2%) and 58 (11.8%), respectively. Generic DAA treatment regimens included sofosbuvir in combination with ribavirin (n = 175), daclatasvir alone (n = 149), ribavirin and peginterferon (n = 80), ledipasvir alone (n = 43), daclatasvir and ribavirin (n = 37), and ledipasvir and ribavirin (n = 6). Overall SVR12 was 95.9% (470/490) for all treatment regimens. SVR12 for treatment naïve and experienced patients was 97.0% (419/432) and 87.9% (51/58), respectively, P = .005. High SVR12 was observed with various regimens, irrespective of genotype and underlying liver disease status. There were no differences in SVR12 with 12 or 24 weeks therapy. No major adverse event occurred requiring treatment stoppage. Generic oral DAAs are associated with high SVR rates in patients with HCV infection in a real-life clinical scenario.

Abstract
BACKGROUND Ribavirin (RBV) is an antiviral agent and the primary component for chronic hepatitis C (CHC) therapy. Hemolytic anemia is limitation for RBV treatment. Inosine triphosphatase (ITPA) activity has been associated with severity of RBV-induced anemia. However, changes in ITPA activity during CHC therapy are unknown. The aim of this study was to measure the time-dependent change in ITPA activity over the RBV treatment. METHODS Forty-two patients with CHC were evaluated for ITPA activity over the course of RBV treatment. RESULTS The median value of ITPA activity at start of RBV treatment was 134.2 μmol/h/g hemoglobin (Hb; range, 26.3-251.0 μmol/h/g Hb). The ITPA activity values at 4, 8, and 12 weeks during RBV treatment were 143.2, 202.2, and 225.7 μmol/h/g Hb, respectively, and these ITPA values were significantly elevated compared with the start of treatment (p < 0.001). In patients with ITPA variants, patients with anemia (Hb < 10 g/dL) had greater elevated ITPA activities compared with patients without anemia at 12 weeks. CONCLUSION Our findings indicate that ITPA activities are elevated with RBV therapy, and this elevation may be a risk of anemia in late therapeutic phase in patients that began with low ITPA activity.

Abstract
PURPOSE Introduction of the direct-acting antivirals (DAAs) for treatment of chronic hepatitis C (CHC) infection has been challenging in all health systems. In Sweden, a national protocol for managed introduction was developed. It was optional, but all county councils agreed to implement and follow it. The purpose of this study was to study (a) cure rates among all patients initiated on treatment in 2014-2015, (b) prescribers' adherence to the drug recommendations and treatment eligibility criteria in the protocol, and (c) introduction rate in the six Swedish healthcare regions. METHOD A cross-sectional study where national data from the Prescribed Drug Register and the quality register InfCare Hepatitis defined the study population, and clinical data from the Patient Register and InfCare Hepatitis were used to monitor outcomes. Descriptive statistics were used. RESULTS A total of 3447 patients were initiated on treatment during 2014-2015. The overall cure rate, based on data from 85% of the cohort, was 96%, with variation between genotypes. Adherence to drug recommendations increased over time and varied between 43.2 and 94.2%. Adherence to the treatment eligibility criteria was initially 80% and increased to 87% when treatment restrictions were widened. The introduction rate differed initially between the regions and reached stable levels 15-18 months after the launch of the first DAA. CONCLUSION The estimated overall cure rate was 96%, with some variations between genotypes. A high level of adherence to the introduction protocol as well as similar introduction rates in the health care regions indicate that the introduction protocol, alongside with other measures taken, contributed considerably to a rapid uptake and equal distribution of DAAs in Sweden.

Abstract
OBJECTIVE Yimitasvir phosphate, an inhibitor of nonstructural protein 5A (NS5A) replication complex of hepatitis C virus (HCV), was evaluated in a double-blind, placebo-controlled, parallel, multiple-dose study. METHODS Twenty-four patients with chronic HCV genotype 1 infection were randomized to receive a 7-day course of yimitasvir phosphate at daily doses of 30, 100 or 200 mg or placebo. Antiviral efficacy, resistance profile, pharmacokinetics (PK), safety and tolerability were assessed. KEY FINDINGS The maximal reduction in HCV RNA from baseline was 5.17 log10 IU/ml. However, most patients experienced viral rebound on or before day 3 after yimitasvir treatment was initiated. The PK profile revealed median peak plasma concentrations at 4-12 h postdose and a mean terminal half-life of 14.47-17.09 h, the basis for daily dosing. Steady drug state was achieved following 5 days of daily dosing. The accumulation rate was low (1.29-1.73). There were no significant alterations in vital signs and laboratory findings among all participants. CONCLUSIONS This study shows that yimitasvir phosphate was well tolerated, and the PK profile supported daily dosing regimens. A 1-week (7-day) treatment course led to a quick and significant reduction in HCV RNA level in this cohort with HCV GT-1 infection.

OBJECTIVE To explore the effectiveness and safety of ombitasvir/paritaprevir/ritonavir and dasabuvir (OBV/PTV/r+DSV) for 12 weeks without ribavirin in adults with chronic HCV genotype 1b infection and compensated cirrhosis. METHODS Observational study of a prospective cohort of adult patients with HCV genotype 1b infection and compensated cirrhosis who received 12 weeks of OBV/PTV/r and DSV without ribavirin. Effectiveness was assessed by recording the percentage of patients achieving sustained virological response at week 12 post-treatment (SVR12). Safety outcomes were based on the incidence of adverse events. RESULTS Seventy-eight patients were included. The SVR12 rate was 96.1% (95%CI 89.2-99.2). Adverse events were recorded in 78.0% of patients. Of these, 97.7% were grade 1/2. One patient discontinued treatment prematurely owing to adverse events. Eighty-six interactions were detected in 43 patients (55.1%). Overall, 81.4% of interactions required close monitoring, alteration of drug dosage, or timing of administration. In 7.0% of cases, the interactions arose from contraindications that required the suspension of the concomitant drug. In 11.6% of cases, medicinal plants or foods were withdrawn. CONCLUSIONS The simplified regimen of OBV/PTV/r+DSV administered for 12 weeks is effective and safe in patients with chronic HCV genotype 1b infection and compensated cirrhosis. No adverse reactions related to drug-drug interactions were recorded.

A different perspective on sofosbuvir-ledipasvir treatment of patients with HCV genotype 1b cirrhosis: The ital-c network study. J Viral Hepat 2018; 25:56-62.

Abstract
The effectiveness of a 12-week course of sofosbuvir-ledipasvir in treatment-experienced HCV genotype 1b-infected patients with cirrhosis is still under debate. Our primary endpoint was to compare the sustained virological response at post-treatment week 12 (SVR12) of sofosbuvir-ledipasvir in combination with ribavirin for 12 weeks, and sofosbuvir-ledipasvir alone for 24 weeks. This was a prospective observational study that enrolled 424 (195 naive, 229 experienced; 164 treated for 12 weeks with Ribavirin and 260 with sofosbuvir-ledipasvir alone for 24 weeks) consecutive HCV genotype 1b-infected patients with cirrhosis. The SVR12 rates were 93.9% and 99.2% in patients treated for 12 and 24 weeks, respectively (P = .002). The baseline characteristics of patients treated for 12 weeks were significantly different from those treated for 24 weeks as regards their younger age (P = .002), prevalence of Child-Pugh class A (P = .002), lower MELD scores (P = .001) and smaller number of nonresponders (P = .04). The shorter treatment was significantly associated with a lower SVR12 in univariate and multivariate analyses (P = .007 and P = .008, respectively). The SVR rate was unaffected by age, gender, BMI, Child-Pugh class, MELD score or previous antiviral treatment. Patients receiving ribavirin experienced more episodes of ascites and headache but less recurrence of hepatocellular carcinoma (HCC), and were prescribed more diuretics and cardiopulmonary drugs. No patient discontinued treatment. The therapeutic regimen of sofosbuvir-ledipasvir plus ribavirin administered for 12 weeks was less effective than sofosbuvir-ledipasvir alone given for 24 weeks. At odds with European guidelines, the recommended 12-week treatment with sofosbuvir-ledipasvir alone might be suboptimal for this setting of patients.

Abstract
INTRODUCTION Chronic Hepatitis C Virus (HCV) infection is common and can cause liver disease and death. Persons born from 1945 through 1965 ("Baby Boomers") have relatively high prevalence of chronic HCV infection, prompting recommendations that all Baby Boomers be screened for HCV. If chronic HCV is confirmed, evaluation for antiviral treatment should be performed. Direct-acting antivirals can cure more than 90% of people with chronic HCV. This sequence of services can be referred to as the HCV "cascade of cure" (CoC). The Tennessee (TN) Department of Health (TDH) and a health insurer with presence in TN aimed to determine the proportion of Baby Boomers who access HCV screening services and appropriately navigate the HCV CoC in TN. METHODS TDH surveillance data and insurance claim records were queried to identify the cohort of Baby Boomers eligible for HCV testing. Billing codes and pharmacy records from 2013 through 2015 were used to determine whether HCV screening and other HCV-related services were provided. The proportion of individuals accessing HCV screening and other steps along the HCV CoC was determined. Multivariable analyses were performed to identify factors associated with HCV screening and treatment. RESULTS Among 501,388 insured Tennessean Baby Boomers, 7% were screened for HCV. Of the 40,019 who received any HCV-related service, 86% were screened with an HCV antibody test, 20% had a confirmatory HCV PCR, 9% were evaluated for treatment, and 4% were prescribed antivirals. Hispanics were more likely to be screened and treated for HCV than non-Hispanic whites. HCV screening was more likely to occur in the Nashville-Davidson region than in other regions of TN, but there were regional variations in HCV treatment. CONCLUSIONS Many insured Tennessean Baby Boomers do not access HCV screening services, despite national recommendations. Demographic and regional differences in uptake along the HCV CoC should inform public health interventions aimed at mitigating the effects of chronic HCV.

Abstract
INTRODUCTION The seroprevalence of hepatitis C virus (HCV) infection tends to be higher in the elderly than in younger populations. Meanwhile, age per sec is an unfavorable determinant that has an impact on liver-related outcomes. Geriatric chronic hepatitis C (CHC) patients would be viewed as a special population and have an urgent need for viral eradication. Areas covered: The antivirals for CHC have evolved from interferon (IFN)-based therapyto interferon-free DAAs. The treatment strategy, in terms of its clinical efficacy and drug safety, in the elderly is presented. Expert opinion: In the previous IFN era, the sustained virological response (SVR) rate of the elderly was lower. More unfavorable safety concerns attributing to the underlying liver disease severity and extra-hepatic presentations further compromised the treatment efficacy. In the IFN-free DAA era, data showing similar SVR rates and safety profiles between the elderly and their counterparts have been demonstrated. Notably, aging is an unfavorable factor for fibrosis regression and HCC development even after HCV eradication. The extent of the improvement of extra-hepatic manifestations in the elderly with SVR is also unclear. The long-term benefits of viral eradication by DAAs in the elderly await further explorations.

Micro-costing analysis of guideline-based treatment by direct-acting agents: the real-life case of hepatitis C management in Brazil. BMC Gastroenterol 2017; 17:119. [PMID: 29169329 PMCID: PMC5701370 DOI: 10.1186/s12876-017-0676-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2017] [Accepted: 11/15/2017] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Eradication of hepatitis C virus (HCV) using direct-acting agents (DAA) has been associated with a financial burden to health authorities worldwide. We aimed to evaluate the guideline-based treatment costs by DAAs from the perspective of the Brazilian Ministry of Health (BMoH). METHODS The activity based costing method was used to estimate the cost for monitoring/treatment of genotype-1 (GT1) HCV patients by the following strategies: peg-interferon (PEG-IFN)/ribavirin (RBV) for 48 weeks, PEG-IFN/RBV plus boceprevir (BOC) or telaprevir (TEL) for 48 weeks, and sofosbuvir (SOF) plus daclastavir (DCV) or simeprevir (SIM) for 12 weeks. Costs were reported in United States Dollars without (US$) and with adjustment for purchasing power parity (PPP$). Drug costs were collected at the National Database of Health Prices and an overview of the literature was performed to assess effectiveness of SOF/DCV and SOF/SIM regimens in real-world cohorts. RESULTS Treatment costs of GT1-HCV patients were PPP$ 43,176.28 (US$ 24,020.16) for PEG-IFN/RBV, PPP$ 71,196.03 (US$ 39,578.23) for PEG-IFN/RBV/BOC and PPP$ 86,250.33 (US$ 47,946.92) for PEG-IFN/RBV/TEL. Treatment by all-oral interferon-free regimens were the less expensive approach: PPP$ 19,761.72 (US$ 10,985.90) for SOF/DCV and PPP$ 21,590.91 (US$ 12,002.75) for SOF/SIM. The overview reported HCV eradication in up to 98% for SOF/DCV and 96% for SOF/SIM. CONCLUSION Strategies with all oral interferon-free might lead to lower costs for management of GT1-HCV patients compared to IFN-based regimens in Brazil. This occurred mainly because of high discounts over international DAA prices due to negotiation between BMoH and pharmaceutical industries.

Abstract
BACKGROUND AND OBJECTIVES Hepatitis C virus infection is common in patients with CKD and leads to accelerated progression to ESRD. Sofosbuvir is a potent direct-acting antiviral therapy against hepatitis C virus; however, there are concerns about its safety in patients with CKD. The objective of our study was to determine the safety and efficacy of sofosbuvir in patients with CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We studied a retrospective observational cohort of patients with CKD defined by eGFR<60 ml/min per 1.73 m2, ≥30 mg albuminuria per 1 g creatinine, or ≥200 mg proteinuria per 1 g creatinine who received sofosbuvir-based therapy in a large health care system. Regression models were constructed to predict likelihood of sustained virologic response, detect adverse events, and examine changes in eGFR from baseline to follow-up. RESULTS Ninety-eight patients with CKD (42% stage 1 or 2 CKD and 58% stage 3 CKD) were included. Mean age was 62 years old, 78% were men, and 65% were white. Additionally, 49% of patients had diabetes, 38% of patients had cirrhosis, and 33% of patients had prior solid organ transplant. Overall sustained virologic response was 81% and varied by regimen used and viral genotype. Average baseline eGFR was equivalent to average on-treatment eGFR, but seven patients experienced a rise in creatinine ≥1.5 times baseline while taking sofosbuvir; all but one recovered. In patients with eGFR<60 ml/min per 1.73 m2 at baseline (stage 3 CKD), regression models showed that hepatitis C cure was associated with a 9.3 (95% confidence interval, 0.44 to 18) ml/min per 1.73 m2 improvement in eGFR during the 6-month post-treatment follow-up period. Adverse events were common (81%), but serious adverse events (17%) and treatment discontinuations (8%) were uncommon. CONCLUSIONS Sofosbuvir-based direct-acting antiviral therapy is safe and effective in a cohort of patients with CKD infected with hepatitis C.

Abstract
BACKGROUND To evaluate the effectiveness and safety of ledipasvir/sofosbuvir (LDV/SOF)±ribavirin (RBV) regimen in a real-world setting. METHODS Patients received a fixed-dose combination tablet containing LDV and SOF with or without RBV, for 8, 12 or 24 weeks. Patients were assessed at baseline, end of treatment, and 12 weeks after the end of treatment. The primary effectiveness endpoint was sustained virologic response 12 weeks after the end of treatment (SVR12). RESULTS Of the 86 patients, aged 20-80 years, 82.6% were HCV genotype 1b-infected and 50.0% were cirrhotic. More than half (52.3%) had previously followed pegylated interferon-containing (PEG-IFN) treatment regimens, and 38.5% were null-responders. SVR12 was achieved by 94.2% of patients. All non-responders were cirrhotic: two demonstrated virologic breakthrough and the remaining three relapsed. All patients treated with an 8-week regimen achieved SVR12 despite having high viral load at baseline (HCV RNA of >1 million IU/mL in 8/10 patients, including one with a viral load of >6 million IU/mL). Adverse events were generally mild and transient. Most frequently, fatigue (22.1%), headache (15.1%), and arthralgia (7.0%) were observed. Laboratory abnormalities included anemia and hyperbilirubinemia. CONCLUSIONS Treatment with LDV/SOF±RBV is an effective and safe option for patients with HCV, including those with advanced liver disease or a history of non-response to PEG-IFN-based therapy.

Abstract
BACKGROUND Direct-acting antiviral (DAA)-based treatment of hepatitis C virus (HCV) has been associated with high sustained virological response (SVR) rates and good tolerability in randomized clinical trials. This study was performed to assess the safety and effectiveness of DAAs in both HCV mono-infected and HIV/HCV co-infected patients. METHODS All consecutive HCV-infected patients, including HIV/HCV co-infected patients, receiving DAA-based treatment from February 2015 to September 2016 at the study clinic were included. Clinical, virological, and biochemical data were retrieved. The primary end-point was the SVR12 (HCV RNA undetectable 12 weeks after the end of treatment) is commonly used worldwide. The secondary end-point was the safety profile of DAAs during the treatment period. RESULTS A total of 382 patients were included; 62 were HIV/HCV co-infected. Cirrhosis was found in 256 patients (67.4%). SVR12 was achieved in 365/382 (95.5%) individuals (58/62 HIV/HCV co-infected, 93.5%) in the intention-to-treat (ITT) analysis. A platelet count <90×109/l (odds ratio (OR) 4.12, 95% confidence interval (CI) 1.5-11.3, p=0.006), HCV genotype 3 infection (OR 5.49, 95% CI 1.9-15.7, p=0.002), liver stiffness >20kPa (OR 3.05, 95% CI 1.03-8.96, p=0.04), and Model for End-Stage Liver Disease (MELD) score >10 (OR 5.27, 95% CI 1.16-23.8, p=0.03) were associated with lower SVR rates. On multivariate analysis, only genotype 3 infection remained a negative predictor of SVR (OR 21.6, 95% CI 3.81-123, p=0.001). Treatment discontinuation was observed in 10 subjects. Severe adverse events (SAEs) occurred in 17 patients (4.5%). CONCLUSIONS High SVR12 rates were observed in both HCV mono-infected and HIV/HCV co-infected individuals. Overall, DAA-based treatment was safe and there were no differences in terms of SAEs and treatment discontinuation between the two groups.

Abstract
BACKGROUND An estimated 170 million individuals worldwide are infected with the hepatitis C virus (HCV). Although treatment options using a combination of pegylated interferon and ribavirin (P-IFN/RBV) are available, sustained clearance of the virus is only achieved in approximately 40% of individuals infected with HCV genotype 1. Recent advances in the treatment of HCV using directly acting antiviral agents have been achieved; however, treatment can be very expensive and is associated with substantial side effects. The development of a new treatment modality is needed. One possible modality could be specific immunotherapy. Terap C is a therapeutic vaccine candidate composed of pIDKE2, a plasmid expressing HCV structural antigens, with a recombinant HCV core protein, Co.120. OBJECTIVE To assess the safety and efficacy of concomitant therapy with the candidate vaccine, Terap C, IFN α-2b and ribavirin in untreated individuals with HCV genotype 1 infection. METHODS This was a Phase II randomized, placebo-controlled, double-blind clinical trial evaluating the safety and efficacy of Terap C concomitant with IFN α-2b/RBV in 92 treatment-naïve patients with HCV genotype 1 infection. The study was conducted at the Gastroenterology Institute in Havana, Cuba. Patients were randomly assigned to 1 of 5 groups. The control group (Group 1) received IFN α-2b/RBV and placebo for 48 weeks. Groups 2 and 3 were administered Terap C 6 and 9 times, respectively, in addition to standard IFN α-2b/RBV treatment. In groups 4 and 5, Terap C was introduced 12 weeks after the initiation of IFN α-2b/RBV and administered 6 and 9 times, respectively, concomitant with IFN α-2b/RBV. RESULTS All patients showed some adverse events. Out of 3615 adverse events, only 18.8% were considered to be probably associated with administration of Terap C. Most events (47.4%) were considered to be improbably associated with of administration Terap C. Only 33.8% were considered possibly temporarily associated with Terap C, and can be explained by the use of conventional IFN α-2b + RBV or by HCV itself. The most common adverse events (≥65%) observed were pain at the injection site, headache, asthenia, psychiatric disturbances, fever, and gastrointestinal symptoms. Regarding sustained virological response, a 20% superiority was observed in the patients who received concomitant Terap C treatments from the beginning of the study compared with those who started after Week 12. CONCLUSIONS Vaccination with Terap C in patients with chronic HCV infection was safe and well tolerated. Clinical trial protocol code: IG/VHI/HC/0701; Public Register Code: RPCEC00000074.
