Enanta to Present New Data for Core Inhibitor for Hepatitis B Virus and FXR Agonist EDP-305 for NASH at The International Liver Congress™ 2018
The abstract titled, “Discovery of a novel HBV core inhibitor EP-027367 with potent antiviral activity both in vitro and in a humanized mouse model” will be presented today at 17:45 CET in an oral presentation. EP-027367 is one of several core inhibitors Enanta is evaluating for hepatitis B virus. Core inhibitors, sometimes referred to as capsid assembly modulators, are a new class of HBV inhibitors that can disrupt the assembly and replication of the virus at multiple steps in the virus lifecycle. Data being presented today will demonstrate that in a chimeric mouse model with human liver cells, EP-027367 reduced hepatitis B virus DNA levels by up to 3.0 logs from baseline in HBV viral titers with 4 weeks of treatment and demonstrated a favorable tolerability and pharmacokinetic profile. EP-027367 has also demonstrated potent, pan-genotypic, anti-HBV activity capable of preventing the establishment of cccDNA in vitro.
There will also be three posters on EDP-305, Enanta’s FXR agonist currently in a Phase 2 study for NASH and a Phase 2 study for PBC. One poster will highlight new preclinical data demonstrating EDP-305 favorably regulates the expression of key fibrogenic genes in vitro and in vivo and a second will show EDP-305 has distinct transcriptional and post-transcriptional regulatory mechanisms for LDLR and SRB1 expression. A third poster will present data from our previously released phase 1 study highlighting the pharmacokinetics, pharmacodynamics and safety of EDP-305 in healthy and presumptive NAFLD subjects. The U.S. Food and Drug Administration has granted EDP-305 Fast Track designation for the treatment of NASH patients with liver fibrosis and Fast Track designation for the treatment of patients with PBC.
The full ILC 2018 scientific program as well as the abstracts can be found at http://ilc-congress.eu/. Further details will be available at the time of these presentations.

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, glecaprevir and paritaprevir, 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 regimens marketed as MAVYRET™ (U.S.) and MAVIRET™ (ex-U.S.) (glecaprevir/pibrentasvir) and VIEKIRA PAK® (paritaprevir/ritonavir/ombitasvir/dasabuvir) (U.S.) and VIEKIRAX® (paritaprevir/ritonavir/ombitasvir) (ex-U.S.).
Royalties 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).
