New drug successfully halts fibrosis in animal model of liver disease
Date:8/7/2012

A study published in the online journal Hepatology reports a potential new NADPH oxidase (NOX) inhibitor therapy for liver fibrosis, a scarring process associated with chronic liver disease that can lead to loss of liver function.

"While numerous studies have now demonstrated that advanced liver fibrosis in patients and in experimental rodent models is reversible, there is currently no effective therapy for patients," said principal investigator David A. Brenner, MD, vice chancellor for Health Sciences and dean of the School of Medicine at the University of California, San Diego. "This new study provides important validation of the role of NOX in liver fibrosis, and suggests that a NOX inhibitor could provide an effective treatment for this devastating disease."

Most chronic liver diseases are associated with progressive fibrosis, which is triggered by the loss of liver cells and the activation of inadequate wound healing pathways. In addition, oxidative stress which results from an inappropriate balance between the production and clearance of highly reactive molecules involved in cell signaling called reactive oxidative species (ROS) leads to aberrant tissue repair in the liver.

When the liver is injured for example, through hepatitis or alcohol abuse HSCs are activated to become myofibroblasts, cells which play a crucial role in wound healing and the body's response to inflammation by recruiting immune cells called macrophages to the injury site. This process, triggered by intracellular signalling pathways involving NOX, can result in an abundance of scarring and eventually result in the loss of organ function.

By inhibiting NOX, the researchers theorized that myofibroblast activation and macrophage recruitment could be interrupted, preventing further fibrosis and potentially allowing regression of established fibrosis.

They assessed the effectiveness of treatment with GKT137831 a NOX1/4 inhibitor developed by Genkyotex SA of Geneva, Switzerland in mouse models, and found that treatment with this NOX inhibitor suppressed ROS production, as well as NOX and fibrotic gene expression.

"These data highlight the excellent pharmacological properties of GKT137831 and the broad potential for its use in fibrotic diseases,'' said Patrick Page, chief development officer at Genkyotex and contributor to the study.

According to Brenner, the next steps include a clinical trial with this drug in patients with liver fibrosis.
