Inventiva announces the publication in Biomedicine & Pharmacotherapy of the results from a preclinical study showing improvement of portal hypertension with lanifibranor treatment

Core Viewpoint - Inventiva announced the publication of preclinical study results indicating that lanifibranor may reduce Portal Hypertension (PH), a significant complication of chronic liver diseases, including MASH and cirrhosis [1][5][6]. Group 1: Study Overview - The study was a collaboration with Ghent University Hospital and evaluated lanifibranor's effects on PH independent of hepatic conditions [2]. - Two distinct mouse models were used: Partial Portal Vein Ligation (PPVL) and common Bile Duct Ligation (cBDL) [3]. Group 2: Results from PPVL Model - In the PPVL model, lanifibranor reduced portal pressure by 28% at 10 mg/kg (p=0.03) and 39% at 30 mg/kg (p=0.001) in a dose-dependent manner [3]. - Improvements were linked to vascular changes in the splanchnic compartment, including reduced blood flow in the superior mesenteric artery (p=0.07) and decreased endothelial cell staining [3]. Group 3: Results from cBDL Model - In the cBDL model, lanifibranor also reduced portal pressure and spleen weight while improving fibrosis [4]. - The treatment decreased dysfunction in Liver Sinusoidal Endothelial Cells (LSEC) and hepatic angiogenesis associated with fibrotic PH [4]. Group 4: Implications for Treatment - The study suggests that lanifibranor could be a therapeutic option for patients with clinically significant PH, addressing both intra-hepatic and extra-hepatic conditions [5][6]. - Prof. Sven Francque highlighted the potential of lanifibranor in managing complications related to portal hypertension in chronic liver diseases [6]. Group 5: About Lanifibranor - Lanifibranor is an orally available small molecule that activates all three PPAR isoforms, designed to induce anti-fibrotic, anti-inflammatory, and beneficial vascular changes [8]. - It is the only pan-PPAR agonist in clinical development for MASH, with Breakthrough Therapy and Fast Track designations from the FDA [8]. Group 6: About Inventiva - Inventiva is focused on developing oral small molecule therapies for MASH and other diseases with significant unmet medical needs [9]. - The company is currently evaluating lanifibranor in the NATiV3 pivotal Phase 3 clinical trial for MASH treatment [9].
