EDP‐297: A novel, farnesoid X receptor agonist—Results of a phase I study in healthy subjects

Article

作者: Luo, Ed ; Oosterhaven, Jart ; van Marle, Sjoerd ; Marotta, Christine ; Ahmad, Alaa ; Adda, Nathalie

AbstractEDP‐297 is a farnesoid X receptor agonist under development for treating nonalcoholic steatohepatitis. The pharmacokinetic (PK), pharmacodynamic (PD), food effect, and safety were evaluated in a single ascending dose (SAD) and multiple ascending dose (MAD) phase I study. Healthy subjects received single EDP‐297 doses of 20–600 μg or once daily doses of 5–90 μg for 14 days. Safety, PKs, and PDs were assessed, including fibroblast growth factor 19 (FGF‐19) and 7‐α‐hydroxy‐4‐cholesten‐3‐one (C4). Among 82 subjects, EDP‐297 was generally well‐tolerated. Pruritus was observed in four subjects in the SAD phase and seven subjects in the MAD phase; four severe cases occurred at 90 μg in the MAD phase, including one that led to drug discontinuation. A grade 2 elevation in alanine aminotransferase occurred with 90 μg. Mean lipid values remained within normal range. Plasma exposures of EDP‐297 increased with SADs and MADs, with mean half‐life following multiple doses of 9–12.5 h. No food effect was observed. Mean FGF‐19 increased and C4 decreased up to 95% and 92%, respectively. EDP‐297 was generally well‐tolerated up to 60 μg MAD, with linear PKs suitable for once daily oral dosing, target engagement, and no food effect.

Further details will be available at the time of these presentations. About Enanta Pharmaceuticals, Inc. Enanta is using its robust, chemistry-driven approach and drug discovery capabilities to become a leader in the discovery and development of small molecule drugs for the treatment of viral infections and liver diseases. Enanta’s research and development programs include clinical candidates currently in development for the following disease targets: respiratory syncytial virus (RSV), SARS-CoV-2 (COVID-19) and hepatitis B virus (HBV). Enanta is also conducting research in human metapneumovirus (hMPV). Enanta’s research and development activities are funded by royalties from hepatitis C virus (HCV) products developed under its collaboration with AbbVie. Glecaprevir, a protease inhibitor discovered by Enanta, is part of one of the leading treatment regimens for curing chronic HCV infection and is sold by AbbVie in numerous countries under the tradenames MAVYRET® (U.S.) and MAVIRET® (ex-U.S.) (glecaprevir/pibrentasvir).

Safety threat forces Enanta to scrap HBV trials — sending discovery team back to drawing board

A Massachusetts biotech will discontinue the development of its oral drug intended to treat patients suffering from chronic hepatitis B infections, the company said Thursday. Enanta Pharmaceuticals will no longer develop EDP-721. The news comes after safety signals were seen in healthy participants in a Phase I trial after they were administered the drug, and despite a clean safety profile demonstrated in preclinical trials. “Patient safety is our top priority, and we have therefore decided to discontinue further development of this compound,” said CEO Jay Luly. “We are committed to developing a functional cure for chronic hepatitis B patients, and remain confident in EDP-514, our HBV core inhibitor, which has demonstrated safe and robust antiviral activity in Phase 1b studies of viremic and NUC-suppressed patients with chronic HBV infection.” Enanta will advance its HBV program after further discovery efforts, Luly said. Hepatitis B is a viral infection that can attack the liver and cause both acute and chronic disease. It is most typically transmitted from mother to child in birth and delivery, as well as through other bodily fluids. An estimated 290 million people around the world have chronic HBV infections. Enanta is currently developing candidates to target respiratory syncytial virus, HBV and Covid-19. Its R&D efforts are funded through royalties from its hepatitis C virus products developed alongside AbbVie. Early last month, the company offloaded in-house development of its two FXR agonist NASH drugs, EDP-305 and follow-up candidate EDP-297, and said it would move to an out-licensing strategy after the early data showed little chance of solo success for either drug. Baird analyst Brian Skorney called the decision “incrementally positive,” remarking that Enanta could focus its work on efforts in Covid-19, RSV and HBV, while avoiding the long, winding road that comes along with NASH. But the latest setback will send the company back to the drawing board again. “We believe that the multiple mechanisms in development for NASH today, which reflect the complex pathophysiology of this disease, make it likely that a combination approach with FXR agonists will ultimately provide the optimal treatment regimen for patients,” Luly said in a statement. Enanta did announce positive data from its Phase Ib study of EDP-514 to treat NUC-suppressed chronic HBV patients. The trial showed that it was safe and well-tolerated, and the data support a once-daily oral dosing regimen.

Enanta Axes Two Farnesoid X Receptor Agonists for NASH

Shares of Enanta Pharmaceuticals are falling this morning after the company announced plans to scrap the development of its two clinical stage farnesoid X receptor (FXR) agonists being developed as a potential treatment for non-alcoholic steatohepatitis (NASH). Instead of continuing to develop the two different assets, EDP-305 and EDP-297, the company intends to seek an out-licensing deal that will further advance the research it began. Enanta plans to maintain its focus and resources on therapies aimed at hepatitis B virus and infectious respiratory diseases, including respiratory syncytial virus (RSV) and SARS-CoV-2, the virus that causes COVID-19. This morning, the Watertown, Mass.-based company said it came to its decision following a preplanned examination from a Phase IIb study of EDP-305, a monotherapy FXR agonist treatment. Although its clinical data determined that a 1 mg dose of the experimental drug provided the best safety and efficacy results, the company decided to scrap the development of the program. And that likely means that the data was not strong enough for Enanta to continue to develop the asset on its own. Jay R. Luly, president and chief executive officer of Enanta Pharmaceuticals, believes that the company's FXR agonists will likely do well as part of a combination treatment for NASH, a growing health concern that currently affects about 16 million people in the United States. EDP-305 was being developed as a monotherapy and EDP-297 was being developed as a follow-on treatment. Luly said both of the FXR agonists are “well-positioned to be an important component of a combination therapy to bring a much-needed treatment to patients with NASH.” The treatment, however, will have to be developed by another company. Luly pointed to the complex pathophysiology of NASH and suggested that some other companies developing therapies for NASH could benefit from Enanta’s research. Enanta certainly isn’t the first company to fail to hit the mark in the NASH space. Nor is it the first company assessing an FXR agonist. Last year, Intercept Pharmaceuticals received a Complete Response Letter from the U.S. Food and Drug Administration for its experimental NASH treatment, obeticholic acid. Multiple companies have also struggled to achieve clinical success. NGM Biopharmaceuticals failed to hit the mark in a Phase IIb study assessing aldafermin, an engineered analog of the human hormone FGF19, earlier this year, while GENFIT ended its development of elafibranor for NASH following a trial failure last year. There are more than 200 different treatments in development for NASH, but none of them have succeeded in the clinic so far. NASH is a progressive liver disease caused by excessive fat accumulation in the liver, inducing chronic inflammation. That inflammation then results in progressive fibrosis, leading to cirrhosis, eventual liver failure, cancer, and death. Advanced fibrosis is associated with a substantially higher risk of liver-related morbidity and mortality in patients with NASH. The disease is projected to become the leading cause of liver transplants in the United States.
