Background and Aims: Non-alcoholic steatohepatitis (NASH) is acknowledged as a severe disease that is associated with a significant burden on patients, payers, and society. However, limited evidence exists on the cost associated with NASH across different countries. This analysis aims to describe the cost associated with the routine care of patients with NASH in France, Germany, and the United States., Methods: Data was sourced from the Gesellschaft für Konsumforschung (now Ipsos) Disease Atlas Real- World Evidence program collected from July through November 2017 in France, Germany, and the United States. Country-level unit cost was estimated from national databases for diagnostic tests and procedures, prescription drugs, hospital stays, and outpatient visits in respective local currency based on 2017 values. These were combined to provide an estimate of the cost of management of confirmed NASH in this specific patient population and are presented as mean cost per patient per year for each country in local currency and as USD adjusted for purchasing power parity for comparison., Results: Annual mean ± standard deviation cost of non-alcoholic steatohepatitis ranged from purchasing power parity USD 1,049±2,461 in Germany to USD 1,723±2,988 in the United States. In all markets, the predominant contributor to cost is healthcare resource use represented by hospitalisation and outpatient visits., Conclusions: This study reveals that costs associated with NASH treatment and management vary across the three countries studied, in part due to differences in healthcare systems but also due to different approaches in managing this disease. Our analysis represents the costs for a specific cohort of patients and further studies are warranted to better understand the progressive impact of NASH on healthcare systems and society.

Background & Aims: EDP-305 is an oral farnesoid X receptor (FXR) agonist under development for the treatment of non-alcoholic steatohepatitis (NASH). Herein, we aimed to assess the efficacy, safety and tolerability of EDP-305 in patients with fibrotic NASH., Methods: In this double-blind phase II study, patients with fibrotic NASH (without cirrhosis), diagnosed by historical biopsy or phenotypically, were randomized to EDP-305 1 mg, EDP-305 2.5 mg, or placebo, for 12 weeks. The primary endpoint was mean change in alanine aminotransferase (ALT) from baseline to Week 12, and the key secondary endpoint was mean change in liver fat content from baseline to Week 12., Results: Between January 2018 and July 2019, 134 patients were randomized and 132 were evaluated. At Week 12, the least squares mean reductions from baseline in ALT for patients receiving 2.5 mg EDP-305 and 1 mg EDP-305 were -27.9 U/L (95% CI 0.03 to 24.9; p = 0.049) and -21.7 U/L (-5.8 to 18.3: p = 0.304), respectively, compared to -15.4 U/L for those receiving placebo. Absolute liver fat reduction was -7.1% (2.0-7.5; p = 0.0009) with 2.5 mg EDP-305, -3.3% with EDP-305 1 mg, and -2.4% with placebo. The most common (≥5%) adverse events were pruritus, nausea, vomiting, diarrhea, headache, and dizziness. Pruritus occurred in 50.9%, 9.1%, and 4.2% of patients in the 2.5 mg, 1 mg, and placebo groups, respectively, and led to study drug discontinuation in 20.8% of patients in the 2.5 mg group and 1.8% in the 1 mg group., Conclusions: EDP-305 reduced ALT levels and liver fat content, providing support for a longer-term trial assessing histological endpoints in patients with NASH.

Background & Aims: Increased de novo lipogenesis creates excess intrahepatic fat and lipotoxins, propagating liver damage in nonalcoholic steatohepatitis. TVB-2640, a fatty acid synthase inhibitor, was designed to reduce excess liver fat and directly inhibit inflammatory and fibrogenic pathways. We assessed the safety and efficacy of TVB-2640 in patients with nonalcoholic steatohepatitis in the United States., Methods: 3V2640-CLIN-005 (FASCINATE-1) was a randomized, placebo-controlled, single-blind study at 10 US sites. Adults with ≥8% liver fat, assessed by magnetic resonance imaging proton density fat fraction, and evidence of liver fibrosis by magnetic resonance elastography ≥2.5 kPa or liver biopsy were eligible. Ninety-nine patients were randomized to receive placebo or 25 mg or 50 mg of TVB-2640 (orally, once-daily for 12 weeks). The primary end points of this study were safety and relative change in liver fat after treatment., Results: Liver fat increased in the placebo cohort by 4.5% relative to baseline; in contrast TVB-2640 reduced liver fat by 9.6% in the 25-mg cohort (n = 30; least squares mean: -15.5%; 95% confidence interval, -31.3 to -0.23; P = .053), and 28.1% in the 50-mg cohort (n = 28; least squares mean: -28.0%; 95% confidence interval, -44.5 to -11.6; P = .001). Eleven percent of patients in the placebo group achieved a ≥30% relative reduction of liver fat compared to 23% in the 25-mg group, and 61% in the 50-mg group (P < .001). Secondary analyses showed improvements of metabolic, pro-inflammatory and fibrotic markers. TVB-2640 was well tolerated; adverse events were mostly mild and balanced among the groups., Conclusions: TVB-2640 significantly reduced liver fat and improved biochemical, inflammatory, and fibrotic biomarkers after 12 weeks, in a dose-dependent manner in patients with nonalcoholic steatohepatitis.

Background & Aims: Nonalcoholic steatohepatitis (NASH) is associated with an increase in healthcare resource use and poor health-related quality of life (HRQoL). We assessed the humanistic and economic burden of NASH, disease management, and patient journey., Methods: We performed a cross-sectional analysis of data, collected from July through November 2017, from the Growth from Knowledge Disease Atlas Real-World Evidence program, reported by physicians in United States, France, and Germany. We extracted demographic and medical data from medical records. Some patients voluntarily completed a survey that provided information on disease history, treatment satisfaction, and patient-reported outcomes., Results: We analyzed data from 1216 patients (mean age, 54.9±12.3 years; 57.5% male; mean body mass index, 31.7±6.9); 64.6% had biopsy-confirmed NASH and comorbidities were recorded for 41.3%. Treatments included lifestyle modification (64.6%) or use of statins (25.0%), vitamin E (23.5%), or metformin (20.2%). Patients with biopsy-confirmed NASH reported more physician (4.5 vs 3.7) and outpatient visits (1.8 vs1.4) than patients with suspected NASH not confirmed by biopsy. Among the 299 patients who completed the survey, 47.8% reported various symptoms associated to their NASH. Symptomatic patients reported significantly lower HRQoL than patients without symptoms., Conclusions: In an analysis of data from 3 countries, we found NASH to be associated with regular use of medical resources; patients with symptoms of NASH had reduced HRQoL. The burden of NASH appears to be underestimated. Studies are needed to determine the burden of NASH by fibrosis stage and disease severity., (Copyright © 2021 The Authors. Published by Elsevier Inc.

Background: Since 1920, a decrease in serum cholesterol has been identified as a marker of severe pneumonia. We have assessed the performance of serum apolipoprotein-A1, the main transporter of HDL-cholesterol, to identify the early spread of coronavirus disease 2019 (Covid-19) in the general population and its diagnostic performance for the Covid-19., Methods: We compared the daily mean serum apolipoprotein-A1 during the first 34 weeks of 2020 in a population that is routinely followed for a risk of liver fibrosis risk in the USA (212,297 serum) and in France (20,652 serum) in relation to a local increase in confirmed cases, and in comparison to the same period in 2019 (266,976 and 28,452 serum, respectively). We prospectively assessed the sensitivity of this marker in an observational study of 136 consecutive hospitalized cases and retrospectively evaluated its specificity in 7,481 controls representing the general population., Results: The mean serum apolipoprotein-A1 levels in the survey populations began decreasing in January 2020, compared to the same period in 2019. This decrease was highly correlated with the daily increase in confirmed Covid-19 cases in the following 34 weeks, both in France and USA, including the June and mid-July recovery periods in France. Apolipoprotein-A1 at the 1.25 g/L cutoff had a sensitivity of 90.6% (95%CI84.2-95.1) and a specificity of 96.1% (95.7-96.6%) for the diagnosis of Covid-19. The area under the characteristics curve was 0.978 (0.957-0.988), and outperformed haptoglobin and liver function tests. The adjusted risk ratio of apolipoprotein-A1 for survival without transfer to intensive care unit was 5.61 (95%CI 1.02-31.0; P = 0.04)., Conclusion: Apolipoprotein-A1 could be a sentinel of the pandemic in existing routine surveillance of the general population.

Background: Effective antiviral treatment (direct-acting antiviral agents (DAAs)), the requirement for a fibrosis score to support DDA reimbursement and a screening strategy, such as the USA baby boomer campaign, should lead to an increased awareness of liver disease severity., Objective: To compare the awareness of liver disease severity between the USA and France, two countries with similar access to hepatitis C virus (HCV) and hepatitis B virus (HBV) treatments, similar rules for treatment reimbursement and similar availability of validated fibrosis tests, but with different policies, as France has no screening., Method: The global database of the FibroTest-ActiTest, including 1,085,657 subjects between 2002 and 2014, was retrospectively analysed. Awareness was defined as the test prescription rate and was compared between the USA and France, according to year of birth, gender and dates of DAA availability and screening campaign (2013-2014)., Results: In the USA 252,688 subjects were investigated for HCV, with a dramatic increase (138%) in the test rate in 2013-2014 (119,271) compared with 2011-2012 (50,031). In France 470,762 subjects were investigated (subjects with HCV and other disease) and the rates were stable. In USA 82.4% of subjects and in France 84.6% were classified as either the highest or lowest priority. The most striking difference was the higher test rate in women born between 1935 and 1944 in France 30,384/200,672 (15.1%) compared with the USA 8035/97,079 (8.3%) (OR=1.98 (95% CI 1.93 to 2.03) p<0.0001). This resulted in twice as many cases of cirrhosis being detected, 2.6% (5191/200,672 women) and 1.3% (1303/97,079), respectively, despite the same prevalence of cirrhosis in this age group (17.1% vs 16.2%) and without any clear explanation as to why they had not been included in the USA screening., Conclusions: This study highlighted in the USA the association between awareness of liver disease and both the HCV campaign and DAA availability. In comparison with France, there was a dramatically lower awareness of cirrhosis in the USA for women born between 1935 and 1944., (Published by the BMJ Publishing Group Limited.

Purpose of Review: Mipomersen has been approved by the US Food and Drug Administration as an orphan drug for patients with homozygous familial hypercholesterolemia (HoFH). In contrast, the European Medicines Agency advised negatively on the use of mipomersen. In this review, we discuss the efficacy and safety considerations for this discrepancy., Recent Findings: On the basis of the results of clinical trials with mipomersen, safety concerns have been raised regarding cardiovascular risk reduction and development of hepatic steatosis. In addition, (long-term) tolerability concerns have been raised predominantly regarding injection site reactions. A pooled analysis of cardiovascular events in phase III trials with mipomersen did not provide evidence for either a positive or negative effect on cardiovascular disease. Although long-term studies with mipomersen are eagerly awaited, hepatic fat content appears to stabilize after 6-12 months notwithstanding continued mipomersen administration., Summary: HoFH is a disease with an unmet medical need for new lipid-lowering therapies. On the basis of a mean 2.9 mmol/l LDL-cholesterol reduction, mipomersen is expected to reduce cardiovascular risk in HoFH. Available evidence suggests that the fat accumulation associated with this treatment differs from steatohepatitis, which is a progressive and damaging liver disease. No evidence is available suggesting that injection site reactions because of mipomersen treatment will result in safety issues.

Unlabelled: Nonalcoholic fatty liver disease is a common cause of chronic liver disease in the general population. Nonalcoholic steatohepatitis (NASH), the aggressive form of nonalcoholic fatty liver disease, is associated with an increased risk of liver-related mortality and cardiovascular disease. At present, a liver biopsy is the only generally acceptable method for the diagnosis of NASH and assessment of its progression toward cirrhosis. Although several treatments have shown evidence of efficacy in clinical trials of varying design, there are no approved treatments for NASH, and published trials are often too divergent to allow meaningful comparisons. There is thus a lack of established noninvasive, point-of-care diagnostics and approved treatment on one hand and a substantial population burden of disease on the other. These provide the rationale for developing consensus on key endpoints and clinical trial design for NASH., Conclusion: This article summarizes the consensus arrived at a meeting of the American Association for the Study of Liver Diseases on the key endpoints and specific trial design issues that are germane for development of diagnostic biomarkers and treatment trials for NASH., (Copyright © 2011 American Association for the Study of Liver Diseases.)
