Enanta Pharmaceuticals Announces Data Presentations at the 2018 NASH-TAG Conference

Dec. 21, 2017 12:30 UTC

WATERTOWN, Mass.--(BUSINESS WIRE)--Enanta Pharmaceuticals, Inc. (NASDAQ:ENTA), a chemistry-driven biotechnology company dedicated to creating and developing small molecule drugs for viral infections and liver diseases, today announced that two presentations on EDP-305, Enanta’s FXR agonist for non-alcoholic steatohepatitis (NASH) and primary biliary cholangitis (PBC), will be presented at the NASH-TAG conference January 4-6, 2018 in Park City, Utah.

Data will be presented from Enanta’s Phase 1 study of EDP-305 in healthy subjects and in subjects with presumptive non-alcoholic fatty liver disease (NAFLD). Top line results were first announced on October 23, 2017, and data from this trial studying the safety, pharmacokinetic, and pharmacodynamic properties of EDP-305 support further clinical evaluation of EDP-305 in NASH and PBC patients.

Also, new preclinical data to be presented will demonstrate that treatment with EDP-305 had a significant therapeutic effect on NASH progression in NASH mouse models, and resulted in decreased liver steatosis, hepatocyte ballooning, and total non-alcoholic fatty liver disease score (NAS).

The following data will be presented during the conference:

Poster Presentation:

  • Pharmacokinetics (PK), pharmacodynamics (PD), and safety/tolerability effects of EDP-305, a novel, once-daily, oral farnesoid X receptor (FXR) agonist in healthy subjects and in subjects with presumptive nonalcoholic fatty liver disease (NAFLD) Alaa Ahmad, Kristen Sanderson, Daniel Dickerson, Nathalie Adda, Enanta Pharmaceuticals, Inc., Watertown, MA USA

Oral Presentation:

  • EDP-305, a highly selective and potent farnesoid X receptor (FXR) agonist, reduces liver steatosis, ballooning, and non-alcoholic fatty liver disease activity score (NAS) in two murine models of non-alcoholic steatohepatitis (NASH) Li-Juan Jiang, Mary Chau, Yang Li and Yat Sun Or, Enanta Pharmaceuticals, Inc., Watertown, MA, USA

About Enanta’s EDP-305 Development Program
Enanta is developing EDP-305, its lead farnesoid X receptor agonist, for the treatment of patients with non-alcoholic steatohepatitis (NASH) and for patients with primary biliary cholangitis (PBC). Data from a Phase 1 clinical study demonstrated that EDP-305 was generally safe and well tolerated over a broad range of single and multiple doses, with pharmacokinetic (PK) data supporting once daily oral dosing. Results also support the ability to administer EDP-305 in future trials at doses that neither elicit clinically significant changes in lipids nor result in pruritus. EDP-305 has been granted Fast Track Designation by U.S. Food and Drug Administration for the treatment of patients with PBC and for NASH patients with liver fibrosis. Enanta plans to initiate a Phase 2 dose-ranging study in PBC patients by the end of 2017 and a Phase 2 dose-ranging study in NASH patients in early 2018.

About EDP-305, a Farnesoid X Receptor (FXR) Agonist
EDP-305 is a potent FXR agonist and Enanta’s lead product candidate being developed for the treatment of NASH and PBC. EDP-305 represents a new class of FXR agonists that has been designed to take advantage of increased binding interactions with the receptor. Further, this non-bile acid class contains steroidal and non-steroidal components, and does not contain the carboxylic acid group that can lead to the formation of taurine and glycine conjugates normally associated with bile acids, which may also be present in other classes of FXR agonists.

About NAFLD, NASH, and FXR
Non-alcoholic fatty liver disease (NAFLD) is the accumulation of excessive fat in the form of triglycerides in patients’ liver cells (steatosis) that is not caused by alcohol. NAFLD is widely considered to be the liver expression of metabolic disease associated with type 2 diabetes, insulin resistance, obesity, and hyperlipidemia. A subgroup of NAFLD patients has liver cell injury and inflammation in addition to excessive fat (steatohepatitis). Progression of this condition leads to non-alcoholic steatohepatitis (NASH). Patients with NASH can develop fibrosis and ultimately cirrhosis of the liver, potentially leading to hepatocellular carcinoma (HCC) or requiring a liver transplant. Farnesoid X receptor (FXR) is a nuclear receptor and a main regulator of bile acid levels in the liver and small intestine. It responds to bile acids by regulating gene transcription of key enzymes and transporters, many of which play important roles in lipid metabolism, insulin resistance, inflammation, and fibrosis.

About Enanta
Enanta Pharmaceuticals has used its robust, chemistry-driven approach and drug discovery capabilities to become a leader in the discovery of small molecule drugs for the treatment of viral infections and liver diseases. Two protease inhibitors, paritaprevir and glecaprevir, discovered and developed through Enanta’s collaboration with AbbVie, have now been approved in jurisdictions around the world as part of AbbVie’s direct-acting antiviral (DAA) regimens for the treatment of hepatitis C virus (HCV) infection, including the marketed regimens MAVYRET™(U.S.) /MAVIRET™ (ex-U.S.) (glecaprevir/pibrentasvir) and VIEKIRA PAK® (U.S.) (paritaprevir/ritonavir/ombitasvir/dasabuvir). Royalties and milestone payments from the AbbVie collaboration are helping to fund Enanta’s research and development efforts, which are currently focused on the following disease targets: non-alcoholic steatohepatitis (NASH)/ primary biliary cholangitis (PBC), respiratory syncytial virus (RSV) and hepatitis B virus (HBV).
