ABSTRACT

Background & Aims: Bulevirtide is a first-in-class entry inhibitor antiviral treatment for chronic hepatitis D. The viral kinetics during bulevirtide therapy and the effect of combining bulevirtide with pegylated-interferon (Peg-IFN) are unknown. Methods: We used mathematical modelling to analyze the viral kinetics in two French observational cohorts of 183 patients receiving bulevirtide with or without Peg-IFN for 48 weeks. Results: The efficacy of bulevirtide in blocking cell infection was estimated to 90.3%, whereas Peg-IFN blocked viral production with an efficacy of 92.4%, albeit with large inter-individual variabilities. The addition of Peg-IFN to bulevirtide was associated with a more rapid virological decline, with a rate of virological response (>2 log of decline or undetectability) at week 48 of 86.9% (95% prediction interval [PI] = [79.7-95.0]), compared with 56.1% (95% PI = [46.4-66.7]) with bulevirtide only. The model was also used to predict the probability to achieve a cure of viral infection, with a rate of 8.8% (95% PI = [3.5-13.2]) with bulevirtide compared with 18.8% (95% PI = [11.6-29.0]) with bulevirtide + Peg-IFN. Mathematical modelling suggests that after 144 weeks of treatment, the rates of viral cure could be 42.1% (95% PI = [33.3-52.6]) with bulevirtide and 66.7% (95% PI = [56.5-76.8]) with bulevirtide + Peg-IFN. Conclusions: In this analysis of real-world data, Peg-IFN strongly enhanced the kinetics of viral decline in patients treated with bulevirtide. Randomized clinical trials are warranted to assess the virological and clinical benefit of this combination, and to identify predictors of poor response to treatment. Impact and implications: Bulevirtide has been approved for chronic HDV infection by regulatory agencies in Europe based on its good safety profile and rapid virological response after treatment initiation, but the optimal duration of treatment and the chance to achieve a sustained virological response remain unknown. The results presented in this study have a high impact for clinicians and investigators as they provide important knowledge on the long-term virological benefits of a combination of Peg-IFN and bulevirtide in patients with CHD. Clinical trials are now warranted to confirm those predictions.

ABSTRACT

Background & Aims: In France, bulevirtide (BLV) became available in September 2019 through an early access program to treat patients with HDV. The aim of this analysis was to evaluate the efficacy and safety of BLV in patients with HIV and HDV coinfection. Methods: Patients received BLV 2 mg ± pegylated interferon-α (pegIFNα) according to the physician's decision. The primary endpoint (per-protocol analysis) was the virological response rate at Week 48, defined as the proportion of patients with undetectable serum HDV RNA or a HDV RNA decline >2 log10 IU/ml from baseline. Results: The characteristics of the 38 patients were as follows: 28 male, mean age 47.7 years, and mean baseline HDV RNA viral load 5.7 ± 1.2 log10 IU/ml. Median HIV viral load and mean CD4 count were 32 (30-65) copies/ml and 566 ± 307/mm3, respectively. Eight patients stopped treatment before Week 48. At Week 48, 10 of 19 patients (52.6%) in the 2 mg BLV group and five of seven patients (71.4%) in the 2 mg BLV + pegIFNɑ group had reached virological response (no HDV RNA available in four patients). At Week 48, seven of 19 patients in the 2 mg BLV group and three of six patients in the 2 mg BLV + pegIFNɑ group had a combined response (virological response and normal alanine aminotransferase level). Conclusions: Adults living with HIV coinfected with HDV can be treated by BLV with a virological response in more than 50% of patients. The combination of BLV and pegIFNɑ showed a strong virological response. Impact and implications: Bulevirtide is the only EMA-approved drug for HDV treatment, and we showed that it can be used in adults living with HIV, with an overall good tolerability. Bulevirtide induces a virological response in more than 50% of patients, suggesting that bulevirtide should be considered as a first-line therapy in this specific population. Bulevirtide in combination with pegIFNα could be used in patients without pegIFNα contraindication. No specific drug-drug interaction is reported.

ABSTRACT

BACKGROUND: In a phase 3 trial, bulevirtide monotherapy led to a virologic response in patients with chronic hepatitis D. Pegylated interferon (peginterferon) alfa-2a is recommended by guidelines as an off-label treatment for this disease. The role of combination therapy with bulevirtide and peginterferon alfa-2a, particularly with regard to finite treatment, is unclear. METHODS: In this phase 2b, open-label trial, we randomly assigned patients to receive peginterferon alfa-2a alone (180 µg per week) for 48 weeks; bulevirtide at a daily dose of 2 mg or 10 mg plus peginterferon alfa-2a (180 µg per week) for 48 weeks, followed by the same daily dose of bulevirtide for 48 weeks; or bulevirtide at a daily dose of 10 mg alone for 96 weeks. All the patients were followed for 48 weeks after the end of treatment. The primary end point was an undetectable level of hepatitis D virus (HDV) RNA at 24 weeks after the end of treatment. The primary comparison was between the 10-mg bulevirtide plus peginterferon alfa-2a group and the 10-mg bulevirtide monotherapy group. RESULTS: A total of 24 patients received peginterferon alfa-2a alone, 50 received 2 mg and 50 received 10 mg of bulevirtide plus peginterferon alfa-2a, and 50 received 10 mg of bulevirtide monotherapy. At 24 weeks after the end of treatment, HDV RNA was undetectable in 17% of the patients in the peginterferon alfa-2a group, in 32% of those in the 2-mg bulevirtide plus peginterferon alfa-2a group, in 46% of those in the 10-mg bulevirtide plus peginterferon alfa-2a group, and in 12% of those in the 10-mg bulevirtide group. For the primary comparison, the between-group difference was 34 percentage points (95% confidence interval, 15 to 50; P<0.001). At 48 weeks after the end of treatment, HDV RNA was undetectable in 25% of the patients in the peginterferon alfa-2a group, in 26% of those in the 2-mg bulevirtide plus peginterferon alfa-2a group, in 46% of those in the 10-mg bulevirtide plus peginterferon alfa-2a group, and in 12% of those in the 10-mg bulevirtide group. The most frequent adverse events were leukopenia, neutropenia, and thrombocytopenia. The majority of adverse events were of grade 1 or 2 in severity. CONCLUSIONS: The combination of 10-mg bulevirtide plus peginterferon alfa-2a was superior to bulevirtide monotherapy with regard to an undetectable HDV RNA level at 24 weeks after the end of treatment.

ABSTRACT

BACKGROUND AND AIMS: Although HCV cure after direct-acting antiviral (DAA) treatment is associated with hepatic and extrahepatic benefits, few studies have assessed the impact of HCV treatment in people with mental disorders (PWMDs). Using quasi-exhaustive national data from the French administrative health care databases (SNDS), we explored whether DAA treatment in PWMDs affected hospitalizations in both psychiatric and non-psychiatric settings. METHODS: All adult PWMDs identified in the SNDS with DAA treatment initiation between 2015 and 2018 and 12 months of data pre- and post-treatment were included. Individuals were algorithmically classified into one or several subgroups: "addictive disorders", "neurotic and mood disorders", "psychotic disorders" and "other psychiatric disorders". A longitudinal approach was used to compare the frequency and duration of hospitalizations one year before and one year after DAA treatment. RESULTS: In total, 17,203 individuals met the inclusion criteria. The number of patients with at least one hospitalization (any type) decreased by 28% after HCV cure. The mean numbers of hospitalizations in non-psychiatric units per patient per year were 1·2 during the pre-DAA period and 0·8 during the post-DAA period (p < 0·0001). Similarly, the number of hospitalizations in psychiatric wards decreased from 1·4 to 1·2 (p = 0.006). The duration of hospital stays decreased from 20·2 days to 16·7 days in non-psychiatric settings (p < 0·0001). These results were also homogeneous and significant across all subgroups. CONCLUSIONS: HCV cure significantly lowered the frequency and duration of hospitalizations during the year following treatment in all PWMDs subgroups, including the psychotic disorders subgroup. FUNDING: This study was funded by Gilead Sciences.

ABSTRACT

BACKGROUND AND AIMS: No direct-acting antiviral is currently approved for acute HCV infection, delaying treatment. We investigated the effectiveness and safety of 8-week glecaprevir/pibrentasvir (G/P) in patients with acute HCV infection. APPROACH AND RESULTS: This noninterventional, single-arm, retrospective chart review was designed to enroll adults/adolescents with acute HCV infection. Analyses were conducted on a full analysis set (FAS; all enrolled) and modified FAS (FAS excluding nonvirologic failures). The primary end point (modified FAS) was sustained virologic response at posttreatment week 12 (SVR12) with superiority to 92.6% threshold determined by historic chronic HCV G/P SVR12 rates. Secondary end points (FAS) included SVR12, on-treatment virologic failure, posttreatment relapse, and reinfection. Adverse events and safety laboratory values were assessed.Overall, 202 adults were enrolled; in the modified FAS, 150/151 (99.3%; 95% CI: 96.3-99.9) achieved SVR12, demonstrating superiority to efficacy threshold. In the FAS, the SVR12 rate was 74.3% and the on-treatment virologic failure rate was 0%. Relapse and reinfection rates after the final treatment visit (FAS) were 0.5% and 3%, respectively; 39 patients had missing SVR12 data. No on-treatment alanine aminotransferase elevations > 3 × upper limit of normal with total bilirubin > 2 × upper limit of normal were reported. All 53 patients with alanine aminotransferase Grade ≥ 2 at baseline improved to Grade 0/1 on treatment. No adverse eventss of hepatic decompensation/failure or leading to G/P discontinuation occurred. Two patients had serious adverse events unrelated to G/P. CONCLUSIONS: Eight-week G/P therapy was effective and well-tolerated in patients with acute HCV infection. Data support further investigation of G/P in acute HCV to shorten care cascades, reduce transmission, and support HCV elimination.

ABSTRACT

BACKGROUND & AIMS: Despite its high prevalence in the western world metabolic dysfunction-associated steatotic liver disease (MASLD) does not benefit from targeted pharmacological therapy. We measured healthcare utilisation and identified factors associated with high-cost MASLD patients in France. METHODS: The prevalent population with MASLD (including non-alcoholic steatohepatitis) in the CONSTANCES cohort, a nationally representative sample of 200,000 adults aged between 18 and 69, was linked to the French centralised national claims database (SNDS). Study participants were identified by the fatty liver index (FLI) over the period 2015-2019. MASLD individuals were classified according as "high-cost" (above 90th percentile) or "non-high cost" (below 90th percentile). Factors significantly associated with high costs were identified using a multivariate logistic regression model. RESULTS: A total of 14,437 predominantly male (69%) participants with an average age of 53 ± SD 12 years were included. They mainly belonged to socially deprived population groups with co-morbidities such as diabetes, high blood pressure, mental health disorders and cardiovascular complications. The average expenditure was €1860 ± SD 4634 per year. High-cost MASLD cost €10,863 ± SD 10,859 per year. Conditions associated with high-cost were mental health disorders OR 1.79 (1.44-2.22), cardiovascular diseases OR 1.54 (1.21-1.95), metabolic comorbidities OR 1.50 (1.25-1.81), and respiratory disease OR 1.50 (1.11-2.00). The 10% high-cost participants accounted for 58% of the total national health care expenditures for MASLD. CONCLUSION: Our results emphasize the need for comprehensive management of the comorbid conditions which were the major cost drivers of MASLD.


Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease in European countries, affecting 4­50% of the European population. Confirmation of diagnosis requires liver biopsy which is an invasive procedure. We studied the healthcare costs of patients with MASLD in order to identify cost predictors and cost drivers. We found that patients cost on average €1860 per year. Conditions associated with high-cost were mental health disorders, cardiovascular diseases, metabolic comorbidities, and respiratory disease.

ABSTRACT

BACKGROUND & AIMS: Non-invasive scores have been proposed to identify patients with fibrotic, metabolic dysfunction-associated steatohepatitis (MASH), who are at the highest risk of progression to complications of cirrhosis and may benefit from pharmacologic treatments. However, data in patients with type 2 diabetes (T2DM) are lacking. The aim of this multicenter prospective study was to perform a head-to-head comparison of FAST (FibroScan-aspartate aminotransferase [AST]), MAST (MRI-AST), MEFIB (magnetic resonance elastography [MRE] plus FIB-4), and FNI (fibrotic NASH index) for detecting fibrotic MASH in patients with T2DM. METHODS: A total of 330 outpatients with T2DM and biopsy-proven metabolic dysfunction-associated steatotic liver disease (MASLD) from the QUID-NASH study (NCT03634098), who underwent FibroScan, MRI-proton density fat fraction and MRE at the time of liver biopsy were studied. The main outcome was fibrotic MASH, defined as NAS ≥4 (with at least one point for each parameter) and fibrosis stage ≥2 (centrally reviewed). RESULTS: All data for score comparisons were available for 245 patients (median age 59 years, 65% male, median BMI 31 kg/m2; fibrotic MASH in 39%). FAST and MAST had similar accuracy (AUROCs 0.81 vs. 0.79, p = 0.41) but outperformed FNI (0.74; p = 0.01) and MEFIB (0.68; p <0.0001). When using original cut-offs, MAST outperformed FAST, MEFIB and FNI when comparing the percentage of correctly classified patients, in whom liver biopsy would be avoided (69% vs. 48%, 46%, 39%, respectively; p <0.001). When using cut-offs specific to our population, FAST outperformed FNI and MAST (56% vs. 40%, and 38%, respectively; p <0.001). CONCLUSION: Our findings show that FAST, MAST, MEFIB and FNI are accurate non-invasive tools to identify patients with T2DM and fibrotic MASH in secondary/tertiary diabetes clinics. Cut-offs adapted to the T2DM population should be considered. IMPACT AND IMPLICATIONS: Among patients with type 2 diabetes (T2DM), identifying those with metabolic dysfunction-associated steatohepatitis and significant fibrosis, who are the most at risk of developing clinical liver-related outcomes and who may benefit from pharmacologic treatments, is an unmet need. In this prospective multicenter study, we compared four non-invasive scores, three based on imaging (MRI or ultrasound technologies) and one on laboratory blood tests, for this purpose, using original and study-specific cut-offs. Our findings show that FAST, MAST, MEFIB and FNI are accurate non-invasive tools to identify patients with T2DM and fibrotic MASH in secondary/tertiary diabetes clinics. Cut-offs adapted to the T2DM population should be considered. TRIAL REGISTRATION NUMBER: NCT03634098.

ABSTRACT

Background and Aims: The liver cancer risk test (LCR1-LCR2) is a multianalyte blood test combining proteins involved in liver cell repair (apolipoprotein A1, haptoglobin), hepatocellular carcinoma (HCC) risk factors (gender, age, gamma glutamyl transpeptidase), a marker of fibrosis (alpha2-macroglobulin), and alpha-fetoprotein, a specific marker of HCC. The aim was to externally validate LCR1-LCR2 in hepatitis B. Methods: Preincluded patients were from the Hepather cohort, a multicenter, multiethnic prospective study in 6071 patients. The coprimary study outcome was the negative predictive value of LCR1-LCR2 at 5 years for the occurrence of HCC and survival without HCC according to the predetermined LCR1-LCR2 cutoffs, adjusted for risk covariables and for chronic hepatitis B treatment and quantified using time-dependent Cox proportional hazards models. A post hoc analysis compared the number of patients needed to screen one cancer by LCR1-LCR2 and PAGE-B. Results: A total of 3520 patients, 191 (5.4%) with cirrhosis, with at least 1 year of follow-up were included. A total of 76 HCCs occurred over a median (interquartile range) of 6.0 years (4.8-7.3) of follow-up. Among the 3367 patients with low-risk LCR1-LCR2, the 5-year negative predictive value was 99.3% (95% confidence interval = 99.0-99.6), with a significant Cox hazard ratio (6.4, 3.1-13.0; P < .001) obtained after adjustment for exposure to antivirals, age, gender, geographical origin, HBe-Ag status, alcohol consumption, and type-2 diabetes. LCR1-LCR2 outperformed PAGE-B for number of patients needed to screen mean (95% CI), 8.5 (3.2-8.1) vs 26.3 (17.5-38.5; P < .0001), respectively. Conclusion: The performance of LCR1-LCR2 to identify patients with chronic hepatitis B at very low risk of HCC at 5 years was externally validated. ClinicalTrials.gov: NCT01953458.

ABSTRACT

BACKGROUND & AIMS: Predictors of response to treatment with peginterferon plus ribavirin are well established. In these post-hoc analyses of the REALIZE study, we sought to identify predictors of response for telaprevir-based triple therapy. METHODS: Patients from the REALIZE study with baseline data for all predictors evaluated (including baseline disease characteristics and demographics, prior treatment response and baseline laboratory assessments) were included in the post-hoc analyses (n = 465). Univariate and multivariate analyses were used to evaluate factors predicting treatment outcomes. RESULTS: Sustained viral response (SVR) rates were 86% in prior relapsers, 63% in prior partial responders and 32% in prior null-responders. In the final multivariate analysis, baseline factors predicting SVR were prior response to treatment [Odds ratio (OR) = 2.80; 95% confidence interval (CI), 2.13-3.69], low-density lipoprotein (LDL) (≥2.6 mmol/L) (OR = 2.11; 95% CI, 1.52-2.93), HCV genotype (OR = 0.58; 95% CI, 0.36-0.93), and maximum alanine amino transferase and aspartate amino transferase (OR = 0.62; 95% CI, 0.40-0.97). CONCLUSIONS: Prior response to peginterferon plus ribavirin treatment and LDL levels are the main independent predictive markers of response with telaprevir-based triple therapy
