- Pharmacodynamics
Elafibranor inhibits bile acid synthesis.4 It was also shown to improve insulin sensitivity, glucose homeostasis, and lipid metabolism.1 In patients with PBC, elafibranor reduced the mean levels of alkaline phosphatase (ALP).4
An in vitro PPAR functional assay showed that both elafibranor and GFT1007 produced activation of PPARalpha (EC50 = 46 nM and 14 nM, respectively, and Emax = 56% and 61%, respectively, relative to reference agonists). The potency of elafibranor and GFT1007 for PPAR-alpha activation exceeded the respective potencies for PPAR-gamma and PPAR-delta activation by approximately 3- to 8-fold.4
- Mechanism of action
Proliferator-activated receptor (PPAR) is a nuclear receptor that regulates numerical cellular processes, including lipid metabolism and inflammation.1 Different subtypes of PPARs have different roles and functions, and two of these subtypes - PPAR-alpha (α) and PPAR-delta (δ) (also known as PPARβ) - have been identified as therapeutic targets for diabetes and lipid disorders.3 PPARα controls lipid flux in the liver and regulates plasma levels of triglycerides and high-density lipoprotein (HDL) cholesterol.1 PPARδ activation leads to fatty acid transport and oxidation, increased HDL levels, and improved glucose homeostasis.1 PPARα and PPARδ also mediate anti-inflammatory actions.1
While the exact mechanism of action has not been fully elucidated, elafibranor and its active metabolite (GFT1007) are dual α and β/δ agonists.2,4 The signalling pathway for PPARδ was reported to include Fibroblast Growth Factor 21 (FGF21)-dependent downregulation of CYP7A1, the key enzyme for the synthesis of bile acids from cholesterol.4
Target Actions Organism APeroxisome proliferator-activated receptor alpha agonistHumans APeroxisome proliferator-activated receptor delta agonistHumans APeroxisome proliferator-activated receptor gamma agonistHumans - Absorption
Following once-daily dosing, the steady state of elafibranor and its major active metabolite, GFT1007, was achieved within seven and fourteen days, respectively.4 The mean (SD) Cmax at steady state was 802 (443) ng/mL for elafibranor and 2058 (459) ng/mL for GFT1007.4 The mean (SD) AUC was 3758 (1749) ng x h/mL for elafibranor and 11985 (7149) ng x h/mL for GFT1007.4
Following once-daily dosing of 80 mg in patients with PBC, the median time to peak plasma concentrations (Tmax) of elafibranor and GFT1007 was 1.25 hours (range: 0.5-2 hours).4
When administered with a high-fat and high-calorie meal, Tmax was delayed by 30 minutes for elafibranor and by 1-hour for GFT1007 compared to in fasted conditions. Under fed condition, mean Cmax and AUC of elafibranor decreased by 50% and 15% respectively and mean Cmax of GFT1007 decreased by 30%, but the AUC was not affected compared to fasted conditions. The difference was not clinically meaningful.4
- Volume of distribution
The mean apparent volume of distribution (Vd/F) of elafibranor in healthy subjects was 4731 L, following a single dose of 80 mg under fasted conditions.4
- Protein binding
Elafibranor and GFT1007 were approximately 99.7% bound to plasma proteins, mostly to serum albumin.4
- Metabolism
Elafibranor is extensively metabolized to form a major active metabolite, GFT1007, the chemical structure of which has not yet been characterized. The mean systemic exposure (AUC) to GFT1007 was 3.2-fold higher than that of elafibranor at steady state. GFT3351, an acyl glucuronide conjugate, is a major inactive metabolite that consists of four stereoisomers. In vitro studies showed that elafibranor was metabolized by 15-ketoprostaglandin 13-Δ reductase (PTGR1), a cytosolic enzyme, to form GFT1007. Elafibranor was also metabolized by CYP2J2, UGT1A3, UGT1A4, and UGT2B7. GFT1007 was further metabolized by CYP2C8, UGT1A3, and UGT2B7.4
- Route of elimination
Following a single 120 mg oral dose (1.5 times the recommended dose) of 14C-radiolabelled elafibranor in healthy subjects, approximately 77.1% of the dose was recovered in feces, primarily as elafibranor (56.7% of the administered dose) and its major metabolite GFT1007 (6.08% of the administered dose). Approximately 19.3% was recovered in urine, primarily as glucuronide conjugate GFT3351 (11.8% of the administered dose). A negligible amount of unchanged elafibranor or GFT1007 was detectable in the urine. Biliary excretion of elafibranor in humans was suggested by the excretion of 60% of orally administered elafibranor in the bile of rats.4
- Half-life
Following a single 80 mg dose under fasted conditions, median elimination half-life was 70.2 hours (range 37.1 to 92.2 hours) for elafibranor, and 15.4 hours (range 9.39 to 21.7 hours) for major active metabolite GFT1007.4
- Clearance
The mean apparent total clearance (CL/F) of elafibranor was 50.0 L/h after a single 80 mg dose under fasted conditions.4

- Nuclear receptor that binds peroxisome proliferators such as hypolipidemic drugs and fatty acids. Once activated by a ligand, the nuclear receptor binds to DNA specific PPAR response elements (PPRE) and modulates the transcription of its target genes, such as acyl-CoA oxidase. It therefore controls the peroxisomal beta-oxidation pathway of fatty acids. Key regulator of adipocyte differentiation and glucose homeostasis. ARF6 acts as a key regulator of the tissue-specific adipocyte P2 (aP2) enhancer. Acts as a critical regulator of gut homeostasis by suppressing NF-kappa-B-mediated pro-inflammatory responses.

- General Function
- Binds water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs (Probable). Its main function is the regulation of the colloidal osmotic pressure of blood (Probable). Major zinc transporter in plasma, typically binds about 80% of all plasma zinc (PubMed:19021548). Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (By similarity). Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner (By similarity). The shared binding site between zinc and calcium at residue Asp-273 suggests a crosstalk between zinc and calcium transport in the blood (By similarity). The rank order of affinity is zinc > calcium > magnesium (By similarity). Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli from ferric transferrin, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli (PubMed:6234017). Does not prevent iron uptake by the bacterial siderophore aerobactin (PubMed:6234017)
