Elafibranor, a dual peroxisome proliferator-activated receptor-α/δ agonist, was investigated in the phase II ELMWOOD trial (NCT05627362).<h3>Methods</h3>This 12-week, double-blind trial enrolled adults with PSC and alkaline phosphatase (ALP) ≥1.5× the upper limit of normal. The primary endpoint was elafibranor safety <em>vs</em>. placebo. Additional endpoints included relative mean change from baseline in ALP and enhanced liver fibrosis (ELF) score.<h3>Results</h3>A total of 68 participants (male: 54.4%; mean age: 46.3 years; inflammatory bowel disease: 55.9%) were randomized to elafibranor 80 mg (n = 22), elafibranor 120 mg (n = 23), or placebo (n = 23). At baseline, 70.6% were on ursodeoxycholic acid, 48.5% had ELF scores >9.8, and the mean ALP level was 369.5 U/L. At Week 12, rates of treatment-emergent adverse events (TEAEs) and TEAEs leading to discontinuation in participants on elafibranor 80 mg, 120 mg, and placebo were 68.2%, 78.3%, and 69.6%, and 4.5%, 4.3%, and 8.7%, respectively. Serious TEAEs occurred only in participants on placebo (4.3%). Participants on elafibranor 80 mg and 120 mg had reductions in ALP <em>vs.</em> placebo (least squares mean treatment difference [95% CI]: −35.3% [−49.2, −21.4] and −54.7% [−68.3, −41.0], respectively). ALP normalization occurred only in participants on elafibranor 80 mg (9.1%) and 120 mg (17.4%). The LS mean treatment differences (95% CI) in change from baseline in ELF scores in participants on elafibranor 80 mg and 120 mg <em>vs.</em> placebo were –0.19 (−0.52, +0.15) and –0.28 (−0.62, +0.06), respectively.<h3>Conclusions</h3>Elafibranor was well tolerated in people with PSC and associated with greater biochemical improvements over 12 weeks compared with placebo. A greater magnitude of response was observed with elafibranor 120 mg compared with 80 mg.<h3>Impact and implications</h3>For people with primary sclerosing cholangitis (PSC), there is a need for a well-tolerated and effective treatment that will enhance quality of life, prevent disease progression, and improve long-term outcomes. Here, we present results from the double-blind period of the phase II ELMWOOD trial in PSC, wherein elafibranor, a peroxisome proliferator-activated receptor-α/δ agonist, demonstrated a favorable safety profile, provided greater biochemical improvements over 12 weeks compared with placebo, and appeared to stabilize markers of fibrosis and improve pruritus. These findings support larger and longer term investigations of elafibranor to explore its therapeutic potential as a treatment for people with PSC.","PeriodicalId":15888,"journal":{"name":"Journal of Hepatology","volume":"35 1","pages":""},"PeriodicalIF":25.7,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143931168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional immunosuppressive regimens that target lymphocytes, such as calcineurin phosphatase inhibitors, corticosteroids, or lymphocyte-depleting antibodies, can only partially mitigate rejection while inducing severe adverse effects. This necessitates the search for novel immunotherapeutic targets.<h3>Methods</h3>We harnessed the power of single-cell RNA sequencing and spatial transcriptome in 24 rat transplanted liver and peripheral blood single nucleated cells (PBMCs) samples to derive gene expression signatures recapitulating 13 cell phenotypes. We used flow cytometry, multifactor assays and multiple recombinant assays to validate <em>in vitro</em> and <em>in vivo</em> the role of the target protein Resistin on human T-cell function, as well as the Resistin-CAP1 interaction. Gold nanoparticles were used to package <em>Retn</em> siRNA sequences to validate the role of <em>Retn</em> knockdown on acute rejection after liver transplantation.<h3>Results</h3>By distinguishing between donor and recipient cells, we delineate the dynamic landscape of immune cells during allograft rejection and their spatial distributions across donors and recipients. Our findings underscore the pivotal role of recipient derived intermediate monocytes in cellular rejection. Using CellChat ligand-receptor analysis, we identify the Resistin-CAP1 pathway as a key mechanism by which intermediate monocytes participate in T cell-mediated rejection reactions. We confirm that Resistin knockdown significantly alleviates acute rejection after rat liver transplantation, markedly extending the survival of recipients using innovative nanogold technology.<h3>Conclusion</h3>These findings offer insights into the dynamic changes in the alloimmune microenvironment, pinpointing intermediate monocytes as potential diagnostic and immunotherapeutic targets during allograft rejection. This study holds significant importance in advancing non-invasive diagnostic technologies and immunotherapeutic strategies for allogeneic rejection.<h3>Impact and implications</h3>This study pioneers the application of spatial transcriptomics in liver transplantation, providing a comprehensive analysis of immune cell spatial distribution, complemented by Souporcell-based chimerism assessment. We demonstrate that intermediate monocytes play a pivotal role in T cell-mediated acute rejection via the Resistin-CAP1 signaling axis. Targeting this pathway using nanogold-siRNA technology effectively mitigates rejection and enhances graft survival. These findings contribute novel insights into the mechanisms of transplant rejection and present promising avenues for the development of targeted therapeutic and diagnostic strategies in liver transplantation.","PeriodicalId":15888,"journal":{"name":"Journal of Hepatology","volume":"25 1","pages":""},"PeriodicalIF":25.7,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to quantify the effect of genetic variants on changes in fibrosis severity per decade in MASLD.<h3>Methods</h3>This cross-sectional study included prospectively recruited adults with MASLD aged 18–70 who underwent magnetic resonance elastography (MRE) and genotyping for <em>PNPLA3, TM6SF2, MBOAT7, GCKR,</em> and <em>HSD17B13</em>. A genetic risk score (GRS) was calculated as the sum of established risk alleles in <em>PNPLA3</em> minus protective variants in <em>HSD17B13</em> (0=low risk, 1=high risk). We also estimated the polygenic risk score-hepatic fat content (PRS-HFC) and the adjusted version (PRS-5). The primary endpoint was the age-related change in liver stiffness measurement (LSM) on MRE by GRS. Findings were validated using an external cohort from Latin America.<h3>Results</h3>Among 570 participants, the median age was 57 [49–64] years, 56.8% were women, and 34.2% were Hispanic. Median MRE was 2.4 [2.1–3.0] kPa, and 51% had high GRS. High GRS was independently associated with increased LSM (β=0.28 kPa, 95%CI:0.12–0.44, p=0.001) per 10-year age increase, while the low GRS group showed no significant difference. Similar findings were observed using PRS-HFC and PRS-5. <em>PNPLA3</em> genotype alone also predicted higher LSM (C/G: β=0.32 kPa, 95%CI:0.02–0.61, p=0.034; G/G: β=0.87 kPa, 95%CI:0.52–1.22, p<0.0001) and G/G genotype was associated with significantly higher LSM by age 44, which was consistent in the validation population.<h3>Conclusion</h3>GRS, PRS-HFC, PRS-5, and <em>PNPLA3</em> genotypes alone are associated with greater fibrosis per decade, resulting in divergent disease trajectories starting in midlife. Assessing genetic risk in MASLD will identify high-risk patients who require more frequent monitoring.<h3>IMPACT AND IMPLICATIONS</h3>This study provides granular evidence that genetic predisposition, particularly the <em>PNPLA3</em> G/G genotype, significantly influences the trajectory of liver fibrosis in patients with metabolic dysfunction-associated steatotic liver disease (MASLD), with a more pronounced impact emerging after the fourth decade of life. These findings highlight the importance of incorporating genetic risk assessment into MASLD management, as it allows for the early identification of high-risk individuals who may benefit from more frequent monitoring and targeted interventions. Given the rising global burden of MASLD, clinicians, researchers, and policymakers should consider integrating genetic stratification into existing risk assessment frameworks to refine screening and surveillance strategies. By optimizing patient selection for non-invasive fibrosis assessment and potential therapeutic interventions, this approach could enhance precision medicine efforts and may improve long-term outcomes.","PeriodicalId":15888,"journal":{"name":"Journal of Hepatology","volume":"21 1","pages":""},"PeriodicalIF":25.7,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
