NovartisNovartis announced today that it has entered into a clinical trial agreement with Allergan plc to conduct a Phase IIb study, involving the combination of a Novartis FXR agonist and Allergan's cenicriviroc (CVC) for the treatment of non-alcoholic steatohepatitis (NASH). The financial details of this transaction are not disclosed.

NASH is the progressive form of non-alcoholic fatty liver disease (NAFLD), which is characterized by the accumulation of fat in the liver, inflammation and fibrosis (scarring), and can eventually lead to cirrhosis and liver failure. NASH is a major cause of liver disease worldwide and the leading cause of liver transplants for people under 50 in the US[1]. There are currently no approved treatments for NASH.

"Our clinical collaboration with Allergan expands our development programs for NASH, bringing together science and expertise to investigate a potential new combination therapy in an effort to make a positive change for people living with this condition," said Vas Narasimhan, Global Head, Drug Development and Chief Medical Officer, Novartis. "We believe that collaboration is key to developing the best possible treatments that are urgently needed for NASH patients."

CVC is a once-daily, oral, Phase III ready potent immunomodulator that blocks two chemokine receptors, CCR2 and CCR5, which are involved in inflammatory and fibrogenic pathways. In the Phase IIb CENTAUR study, CVC demonstrated a clinically meaningful improvement in fibrosis of at least one stage without worsening of NASH after one year of treatment, which is one of only two approvable Phase III endpoints. With its unique Mechanism of Action (MOA) and its favorable safety profile, CVC represents an ideal candidate to become the backbone of NASH multi-therapy treatment. CVC has been granted Fast Track designation by the US Food and Drug Administration (FDA) in patients with NASH and liver fibrosis.

Novartis is developing Farnesoid X receptor (FXR) agonists for the treatment of chronic liver diseases, including NASH. The most advanced investigational compound is a potent, non-bile acid FXR agonist, which recently received Fast Track designation from the FDA and is in a Phase II clinical trial. As part of this agreement, Novartis and Allergan will conduct a Phase IIb clinical trial to assess the safety, efficacy and tolerability of a combination therapy for NASH.

In December 2016, Novartis announced an exclusive option for a collaboration and license agreement with Conatus Pharmaceuticals Inc. to jointly develop emricasan for NASH. Emricasan is an investigational, first-in-class, oral, pan-caspase inhibitor and our agreement with Conatus has the potential to expand treatment options for people in various stages of NASH, including those with the advanced form of the disease, NASH cirrhosis. Both collaborations with Conatus and Allergan continue to support the growing Novartis portfolio to develop new therapies in chronic liver diseases, including NASH.

About Novartis FXR agonists
Novartis scientists began to develop leads for the FXR agonism program in 2007. Through this effort, several non-bile acid FXR agonists have been identified and pre-clinical data demonstrates that these compounds are very selective with differentiated biological profiles. FXR agonists have been shown to address three of the most important aspects of NASH progression by reducing fat, inflammation and fibrosis in the liver. First-in-human studies have continued to support their differentiated profiles and their potential for further development. Two Novartis FXR agonists are now in worldwide clinical studies in NASH patients and both have received Fast Track designation status from the FDA.

About Non-Alcoholic Steatohepatitis (NASH)
NASH is a chronic, progressive form of non-alcoholic fatty liver disease. It is a leading cause of liver disease worldwide and it is estimated to affect 3% to 5% of the US population alone[2]. As fat builds up in the liver, it triggers a vicious cycle of chronic inflammation and liver scarring called fibrosis. Over time, liver inflammation and fibrosis may progress to cirrhosis, which can lead to liver failure and, barring a transplant, death. NASH is expected to be the principal cause of liver transplantation in the US by 2020[3] and is currently the leading cause of liver transplants for people under 50 in the US[1].
