NASH PRECLINICAL CRO SERVICES

The increase in the global prevalence of NASH (Non-Alcoholic Steatohepatitis) has turned into an epidemic, urgently requiring effective therapies. Physiogenex provides high quality NASH preclinical CRO services in order to help clients develop new treatments for NASH and liver fibrosis. We provide outstanding scientific expertise, unique in vivo NASH models and golden standards in NASH biomarkers, histology analysis and blinded NAS scoring.

As a pioneer preclinical CRO in the NASH and liver fibrosis field, we help our clients to move forward quickly with their drug candidates. We deliver original, diet-induced and benchmarked animal models of human NAFLD/NASH to evaluate novel drugs efficacy. Our very fast (3 to 8 weeks) NASH models allow to rapidly demonstrate the potency of our clients’ compounds. To further confirm the drug efficacy, diet-induced NASH models with concomitant obesity, insulin resistance and dyslipidaemia can be used.

In each NASH model, client drugs can be compared with clinical benchmarks: elafibranor, obeticholic acid and liraglutide.
