BOSTON — Aug. 7, 2018 — Albireo Pharma, Inc. (Nasdaq:ALBO), a clinical-stage orphan pediatric liver disease company developing novel bile acid modulators, today announced financial results and corporate highlights for the second quarter ended June 30, 2018.

“The first half of 2018 was defined for Albireo by initiation of our Phase 3 program for A4250 in progressive familial intrahepatic cholestasis (PFIC),” said Ron Cooper, President and Chief Executive Officer of Albireo. “Notably, A4250 also received rare pediatric disease designation from the FDA, making Albireo eligible to apply for a priority review voucher upon submission of a new drug application for A4250. At the same time, we secured U.S. and EU method of use patents for elobixibat in the treatment of NASH, shared important findings on cholestatic liver disease at two scientific meetings, continued to strengthen our understanding of the cholestatic liver disease population and made key board and management appointments for our company.”

Recent Highlights

Advanced A4250 Program

• Enrolled the first patient in thePEDFIC-1 study, held successful E.U. and U.S. investigators meetings and continued activating trial sites. Twelve sites were initiated in seven countries as of the end of July.PEDFIC-1 is a randomized, double-blind, placebo-controlled Phase 3 clinical trial of A4250 in patients ages 6 months to 18 years with PFIC (subtype 1 or 2) who have elevated serum bile acid (sBA) levels and pruritus. Data generated from this study are expected to support potential drug approval applications for A4250 in the U.S. and European Union Topline data currently are expected in late 2019 or early 2020.

• Reported data on a pharmacodynamic marker measured in the completed Phase 2 clinical trial of A4250 in children with cholestatic liver disease and pruritus at the European Association for the Study of the Liver (EASL) The International Liver Congress™. Treatment with A4250 decreased lysophospholipase autotaxin (ATX) levels in most patients, and there was a statistically significant correlation with a reduction in serum bile acids (sBA) (r=0.60; p=0.003). Pruritus intensity at baseline was significantly correlated with baseline levels of ATX (r=0.67; p=0.001).

• Presented data from two studies on cholestatic liver disease at the European Society for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Annual Meeting.

• Data from a qualitative study supporting the development of Albireo’s proprietary Patient Reported Outcome (PRO) and Observer Reported Outcome (ObsRO) tools that are being used to measure pruritus in thePEDFIC-1 study illustrated the significant impact that pediatric cholestatic liver diseases, such as PFIC, have on quality of life.

• Research from a systematic literature review of partial external biliary diversion (PEBD) surgery in patients with PFIC found that changes in sBA and bilirubin appear useful as biomarkers in predicting both early and long-term outcomes. sBA responder rate is the primary endpoint in Europe and a key secondary endpoint in the U.S. in thePEDFIC-1 study.

• Participated in a PRIority MEdicines (PRIME) programkick-off meeting at the European Medicines Agency (EMA) that included the rapporteur. PRIME provides enhanced early dialogue with EMA to facilitate accelerated assessment of therapies considered to be priority medicines.

• Received rare pediatric disease designation from the FDA for A4250 in PFIC, affirming Albireo’s eligibility to apply for a priority review voucher upon submission of a new drug application for A4250. A4250 has received orphan drug designation for PFIC in the U.S. and E.U.

• Continued progress in commercialization planning for A4250 with completed qualitative, quantitative and pricing comparison market research on PFIC and other cholestatic liver diseases.

Elobixibat

• Positive Phase 3 trial results from Albireo licensee EA Pharma Co, Ltd. were presented at Digestive Disease Week (DDW) during a Distinguished Abstract Plenary Session. Data from this study demonstrated that elobixibat, afirst-in-class IBAT inhibitor, resolved constipation in the short term, and improved bowel function and patient quality of life with long-term use in patients with chronic constipation in Japan. Elobixibat was well tolerated, with the most common side effects being mild gastrointestinal disorders. The data were published inThe Lancet Gastroenterology & Hepatology.

• Granted a patent for a method of using elobixibat to treat NASH in both the U.S. and Europe.

Corporate

• Elected Anne Klibanski, M.D., and Stephanie Okey, M.S., to Albireo’s Board of Directors

• Added Patrick Horn, M.D. as Chief Medical Officer and Jason G. Duncan, J.D., as General Counsel and Secretary to the leadership team.

• Presented at multiple investor conferences, including Jefferies 2018 Global Healthcare Conference and Deutsche Bank 43rd Annual Health Care Conference.

• Selected for inclusion in the Russell 2000^® Index as part of the annual reconstitution of the Russell stock indexes.
