Barcelona Liver Bioservices (BLB), CRO especially focused on the field of Hepatology, announced today the presentation of an original communication at The EASL Congress held in Vienna and organized by the European Association for the Study of Liver Diseases (EASL).

Poster #WED-524 “GTX-011 improves fibrosis and hepatic stellate cells phenotype in human precision cut liver slices” will be presented from 13:00 – 14:30h by Prof Dr Jordi Gracia-Sancho, co-founder and CSO of BLB. The study assesses the effects of GTX-011, a first-in-class drug with anti-inflammatory and anti-fibrotic properties mediated by the inhibition of the TGFβ pathway, in Precision-Cut Liver Slices (PCLS) from human liver tissues. PCLS represent a unique 3D ex vivo model that preserves the structure and cellular composition of the liver, constituting an intermediate step between pre-clinical and clinical research.

The results of this study revealed that treatment of human liver slices with GTX-011 promoted hepatic stellate cells (HSCs) de-activation and inhibition of pro-fibrogenic pathways. Furthermore, gene deconvolution analysis was performed combining our transcriptomic data with previously published single-cell RNAseq data, in order to better understand the changes in the phenotype of each liver cell type in response to treatment. This advanced bioinformatic analysis confirmed the effects of GTX-011 on HSCs, promoting their de-activation compared to vehicle-treated tissues.

Barcelona Liver Bioservices (BLB) announced today the presentation of an original communication at the annual meeting of the American Association for the Study of the Liver (AASLD), held as The Liver Meeting Digitial Experience.

Poster #1914 “GTX-011 improves portal hypertension, liver fibrosis and endothelial dysfunction in a rat model of non-alcoholic steatohepatitis” will be presented by Zoe Boyer, Senior Associate Scientist at BLB. The study, fruit of the collaboration between BLB and GAT Therapeutics, describes for the first time the effects of the novel non-steroidal modulator of 3C nuclear receptors GTX-011 in a pre-clinical model of NASH. Results of the study show that rats receiving GTX-011 exhibited significant improvement in portal hypertension, considered the most detrimental complication of advanced liver disease. Underlying mechanisms of this hemodynamic improvement included amelioration of liver sinusoidal endothelial cells (showing improved vasodilator and anti-inflammatory mediators), together with amelioration in the metabolic profile (reduced FFA and insulin resistance). Importantly, GTX-011 administration led to partial de-activation of hepatic stellate cells. “We are glad to describe in detail the benefits of this compound in a pre-clinical model of NASH that particularly recapitulates the main pathophysiological features and transcriptome de-regulations of the human disease”, stated Dr Gracia-Sancho, co-founder and CSO of BLB.
