Additional Results of Global Primary Biliary Cirrhosis Study Group Analysis to be Presented at AASLD Annual Meeting

Data Support Strong Statistical Association of PBC Biochemical Endpoint with Clinical Outcomes

NEW YORK, Oct. 1, 2013 /PRNewswire/ — Intercept Pharmaceuticals, Inc. (NASDAQ: ICPT)(Intercept), a clinical stage biopharmaceutical company focused on the development and commercialization of novel therapeutics to treat chronic liver diseases such as primary biliary cirrhosis, today announced that two analyses by the Global Primary Biliary Cirrhosis (PBC) Study Group (also known as the PBC Supergroup) have been accepted for oral presentation at the 64th Annual Meeting of the American Association for the Study of Liver Diseases (AASLD), taking place November 1 — 5 in Washington, D.C.

Data from over 3,895 PBC patients collected and pooled by an independent group of 15 academic medical centers across eight countries have been analyzed by the Global PBC Study Group. These analyses are expected to further confirm that the surrogate biochemical endpoint used by Intercept in its ongoing Phase 3 POISE trial (i.e., alkaline phosphatase (ALP) < 1.67x upper limit of normal and normal bilirubin) is strongly predictive of adverse clinical outcomes in PBC patients.

“This international collaboration has assembled data from the largest group of PBC patients to have ever been evaluated since PBC was first described over 150 years ago,” commented Dr. Henk van Buuren, one of the principal investigators at Erasmus University Medical Centre. “The data show that abnormal biochemical values predict a higher risk of adverse clinical outcomes.  We believe that our results will facilitate the development of new drugs by clearly establishing meaningful biochemical goals for therapy and enable physicians to determine if a given treatment is effective. PBC is a rare disease and we are very grateful to our colleagues at the many participating institutions around the world for sharing their data.”

The two abstracts from the Global PBC Study Group can be accessed through the AASLD website, www.aasld.org.

Primary Biliary Cirrhosis and the Global PBC Study Group
PBC is an autoimmune chronic liver disease that typically affects women. The disease progresses in those patients who have an inadequate response to therapy and may require a liver transplant or die. Biochemical assessments of liver function, particularly by measuring plasma levels of ALP and bilirubin, are typically used by physicians to diagnose and manage PBC patients.  There is a log-linear relationship between ALP levels and transplant-free survival; higher levels are associated with a worse prognosis. Accordingly, the relationship between these biochemical assessments of liver function and adverse clinical outcomes is highly important in the selection of appropriate endpoints in therapeutic clinical trials.

Data from the Global PBC Study Group are being analyzed under the direction of Dr. Bettina Hansen, Dr. Henk van Buuren and colleagues at Erasmus University Medical Centre in Rotterdam, The Netherlands. Intercept is sponsoring this independent academic research program but is not involved in the data collection and analysis. In April 2013, the Global PBC Study Grouppresented an analysis of data from over 2,100 patients at the annual meeting of the European Association for the Study of the Liver (EASL).  These preliminary data demonstrated that the primary endpoint being used in Intercept’s Phase 3 POISE trial is highly statistically predictive of liver transplant-free survival in PBC patients.

About Intercept
Intercept is a biopharmaceutical company focused on the development and commercialization of novel therapeutics to treat orphan and more prevalent liver diseases utilizing its expertise in bile acid chemistry. The company’s lead product candidate, obeticholic acid (OCA), is a bile acid analog and first-in-class agonist of the farnesoid X receptor (FXR). OCA is initially being developed for the second line treatment of primary biliary cirrhosis (PBC) in patients with an inadequate response to, or who are unable to tolerate, ursodiol, the only approved therapy for this indication. OCA has received orphan drug designation in both the United States and Europe for the treatment of PBC. Intercept owns worldwide rights to OCA outside of Japan and China, where it has out-licensed the product candidate to Dainippon Sumitomo Pharma.
