Biological Activity

Description Elafibranor is an agonist of the peroxisome proliferator-activated receptor-α(PPAR-alpha) and peroxisome proliferator-activated receptor-δ(PPAR-δ). It improves insulin sensitivity, glucose homeostasis, and lipid metabolism and reduces inflammation.
Targets
PPARα [1]
()
PPARδ [1]
()
In vitro GFT505 is a novel PPAR modulator that shows a preferential activity on PPAR-α and concomitant activity on PPAR-δ[2].
In vivo Elafibranor (GFT505) is a dual PPARα/δ agonist that has demonstrated efficacy in disease models of nonalcoholic fatty liver disease (NAFLD)/NASH and liver fibrosis. In the rat, GFT505 concentrated in the liver with limited extrahepatic exposure and underwent extensive enterohepatic cycling. Elafibranor confers liver protection by acting on several pathways involved in NASH pathogenesis, reducing steatosis, inflammation, and fibrosis. GFT505 improved liver dysfunction markers, decreased hepatic lipid accumulation, and inhibited proinflammatory (interleukin-1 beta, tumor necrosis factor alpha, and F4/80) and profibrotic (transforming growth factor beta, tissue inhibitor of metalloproteinase 2, collagen type I, alpha 1, and collagen type I, alpha 2) gene expression[1].

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

Elafibranor (code name GFT505) is a multimodal and pluripotent medication for treatment of atherogenic dyslipidemia for an overweight patient with or without diabetes. It is an oral treatment that acts on the 3 sub-types of PPAR (PPARa, PPARg, PPARd) with a preferential action on PPARa. As of February 2016, elafibranor has completed 8 clinical trials and a phase III is in progress.

Elafibranor (INN,[2] code name GFT505) is an experimental medication that is being studied and developed by Genfit for the treatment of cardiometabolic diseases including diabetesinsulin resistancedyslipidemia, and non-alcoholic fatty liver disease (NAFLD).[3][4][5]

Elafibranor is a dual PPARα/δ agonist.[6][7]

Elafibranor is an agonist of the peroxisome proliferator-activated receptor-α(PPAR-alpha) and peroxisome proliferator-activated receptor-δ(PPAR-δ). It improves insulin sensitivity, glucose homeostasis, and lipid metabolism and reduces inflammation

FT505 is an oral treatment that acts on the 3 sub-types of PPAR (PPARa, PPARg, PPARd) with a preferential action on PPARa. It has a sophisticated mechanism of action. It is able to differentially recruit cofactors to the nuclear receptor, which subsequently lead to differential regulation of genes and biological effect. Therefore, the ability to identify and profile the activity of selective nuclear receptor modulator (SNuRMs) is a powerful approach to select innovative drug candidates with improved efficacy and diminished side effects. These pluripotent and multimodal molecules have significant positive effects on obesity, insulin-resistance and diabetes, atherosclerosis, inflammation, and the lipid triad (increasing of HDL cholesterol, lowering of triglycerides and LDL cholesterol).

Clinical studies

Administered to over 800 patients and healthy volunteers to date, elafibranor has demonstrated:

  • beneficial properties for non-alcoholic steatohepatitis (NASH)[8]
  • improvement of insulin sensitivity and glucose homeostasis[9]

Phase 2b (GOLDEN) results were published online in Gastroenterology in February 2016[10] and will be fully available in the paper version in May 2016.

As of February 2016, elafibranor has completed 8 clinical trials and a phase III is in progress.[11]

Pre-clinical studies

Efficacy on histological NASH parameters (steatosis, inflammation, fibrosis) in animal disease models — anti-fibrotic activities.[12]

The absence of safety concern has been confirmed in a full toxicological package up to 2-year carcinogenicity studies and cardiac studies (in mice).[13]

The liver is one of the most important organs of the body, is one of the highest organ of risk. Many factors can lead to liver disease. For example, drinking too much can lead to cirrhosis, excessive medication can lead to liver damage and even obesity can lead to fatty liver. Thus, the pharmaceutical treatment of fatty liver diseases has become a hot spot of bio-pharmaceutical development.

French Genf biopharmaceutical company said recently that the US Food and Drug Administration has agreed to continue the development of peroxisome proliferator-activated receptor α / δ dual agonist GFT505, and begin Phase IIb study in the United States. GFT 505 is expected to rule early diagnosis of fatty liver, heart disease and its complications, prevention and treatment of diabetes-related lipid hyperlipidemia. French Food and Drug Administration approval to a detailed in-depth far for preclinical and clinical data were analyzed based. Experts expressed the Authority, GFT505 to ensure safe operation and research and can lead to liver cancer or liver cirrhosis related biomarkers all favorable. GFT505 structure as shown in formula III.
