BOSTON — March 7, 2019 (GLOBE NEWSWIRE) — 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 year ended December 31, 2018, and provided a pipeline update.

“In 2018, Albireo successfully delivered according to plan,” said Ron Cooper, President and Chief Executive Officer of Albireo. “The year was highlighted by the start of the A4250 PEDFIC 1 Phase 3 study in PFIC and the approval of elobixibat in Japan for chronic constipation, which made elobixibat the first IBAT inhibitor approved in the world and validated our bile acid scientific platform.

“As positive as last year was, we anticipate 2019 will be truly transformative, with the potential for Phase 3 results in PFIC, initiation of a second rare pediatric cholestatic liver disease pivotal program, and a move into nonalcoholic steatohepatitis (NASH) with an elobixibat Phase 2 trial initiation. Our team is energized for the year ahead.”

Recent Highlights

·Achieved trial site activation target for the A4250 PEDFIC 1 Phase 3 pivotal study. We currently have 37 trial sites active in the U.S., Europe and ROW as of February 28, 2019, and we continue to expect topline trial results end of 2019 or early 2020.

·Received multiple key regulatory designations that support our development program across indications, including fast track designation from the U.S. Food and Drug Administration (FDA) for A4250 in the treatment of pruritus in PFIC, orphan drug designation from the FDA for A4250 in Alagille syndrome, and orphan designation from both the FDA and the European Commission for A4250 in biliary atresia.

·Announced the presentation of important findings in PFIC and other cholestatic liver diseases at NASPGHAN and AASLD, illustrating the unmet need in PFIC and the potential impact of A4250. Results presented at NASPGHAN demonstrate that lower serum bile acids and bilirubin after partial external biliary diversion (PEBD) surgery are associated with decreased aggregate need for liver transplant in PFIC patients. Findings presented by the NAPPED Consortium at AASLD The Liver Meeting demonstrate the association of native liver survival rates and serum bile acid levels.

·Presented at the William Blair Biotech Focus Day event “Bay Area Innovation” and the Jefferies 2018 London Healthcare Conference.

·Strengthened senior management team with the appointment of Simon Harford as Chief Financial Officer and Treasurer, Patrick Horn as Chief Medical Officer and Jason Duncan as General Counsel.

Pipeline Update

·Planning for PEDFIC 1 topline results end of 2019 or beginning of 2020.

·Planning a major step toward realizing the larger opportunity for A4250. Preparing to initiate a pivotal trial in biliary atresia with A4250 in the second half of 2019. Biliary atresia may be the largest of the rare pediatric liver diseases of primary initial interest for A4250. Have received orphan designations for A4250 in biliary atresia in U.S. and EU, and engaged regulators on trial design. We continue to see potential for A4250 beyond PFIC and biliary atresia, and are evaluating other indications.

·Planning a significant development effort in NASH. Preparing to initiate a Phase 2 trial with elobixibat in Q2 and continue to progress preclinical novel bile acid modulators for NASH, all of which are potential candidates for partnering in the future.

Financial Update for the Year Ended December 31, 2018

·Revenues were $12.7 million for the year ended December 31, 2018

·R&D expense was $31.7 million, up 144.3% compared to $13.0 million for the year ended December 31, 2017.

·G&A expense was $18.1 million, up 18.5% compared to $15.2 million in the same period of 2017.

·Net Loss was $46.1 million, or $(3.94) per share, compared to $24.4 million, or $(3.12) per share for the year ended December 31, 2017.

·The Company had cash and cash equivalents at December 31, 2018 of $163.9 million, compared to $53.2 million at December 31, 2017.

Financial Guidance

For the full year 2019, we anticipate total expenses, including R&D and G&A expenses, to be in the range of $75-$80 million. We expect our current cash balance to be sufficient to meet our operating needs into 2021.
