Item 8.01 Other Events.

On April 12, 2023, the Company provided the following updated overview of its business: The Company is a biopharmaceutical company focused on the identification, acquisition, development and commercialization of novel therapies for debilitating rare and orphan diseases. The Company focuses on diseases for which the unmet medical need is high and the biology for treatment is clear. The Company’s product, LIVMARLI® (maralixibat) oral solution (“Livmarli”), a novel, orally administered, minimally-absorbed ileal bile acid transporter (“IBAT”) inhibitor, is approved for the treatment of cholestatic pruritus in patients with Alagille syndrome (“ALGS”) one year of age and older in the United States and for the treatment of cholestatic pruritus in patients with ALGS two months and older in Europe. The Company believes the prevalent patient population in the United States is approximately 2,000 to 2,500 pediatric ALGS patients, which, based on the Company’s current expectations and beliefs, represents a greater than $500.0 million market opportunity. ALGS is estimated to impact one out of every 30,000 births globally. The Company markets and commercialize Livmarli in the United States and certain countries in Europe through its specialized and focused commercial team. The Company has also entered into license and distribution agreements with several rare disease companies for the commercialization of Livmarli in additional countries. The Company is also developing Livmarli for progressive familial intrahepatic cholestasis (“PFIC”) and biliary atresia. Livmarli has been granted breakthrough therapy designation by the U.S. Food and Drug Administration (“FDA”) for ALGS and PFIC type 2. The Company has submitted positive data from its Phase 3 study of Livmarli in patients with PFIC in a supplemental New Drug Application to the FDA seeking approval for the treatment of cholestatic pruritus in patients with PFIC. The Company also expects to report topline data from its EMBARK Phase 2b clinical trial in biliary atresia in the second h
