CBC-backed Jadeite Medicines Announces Exclusive Licensing Agreement with Albireo Pharma to Develop and Promote Odevixibat in Japan

TOKYO,Oct. 12,2021 -- Jadeite Medicines Inc. ("Jadeite"),a biopharmaceutical company that is backed by Singapore's CBC Group ("CBC") and committed to addressing critical unmet medical needs for patients in Japan,today entered into an exclusive licensing agreement with Albireo Pharma,Inc. (Nasdaq: ALBO) for the development and commercialization of odevixibat in Japan for progressive familial intrahepatic cholestasis (PFIC),Alagille syndrome (ALGS) and biliary atresia.

Under the terms of the agreement,Albireo will receive an upfront payment of US$15 million and will be eligible to receive up to US$120 million in milestone payments,as well as double-digit royalties. Jadeite will be responsible for clinical development,regulatory approval and commercialization of odevixibat in Japan,where there is significant market opportunity. Jadeite is backed by CBC,which partners with the world's top entrepreneurs and scientists and leverages its unique "investor-operator" approach to empower global leading healthcare companies to widen access to affordable medical care,catalyze innovations and improve efficiency in fulfilling unmet medical needs worldwide.

"We are excited to partner with Albireo to accelerate delivery of odevixibat to children living with rare liver diseases,initially targeting PFIC,followed by potentially biliary atresia and Alagille syndrome,which all represent significant unmet medical needs in Japan," said Eiichi Takahashi,M.D.,Ph.D.,Chief Executive Officer of Jadeite Medicines. "This agreement reinforces Jadeite's commitment and vision to develop highly differentiated and innovative medicines to improve the health and quality of life of patients in Japan."

"This agreement exemplifies Albireo's commitment to providing global availability of Bylvay,particularly in areas like Japan where high prevalence translates to a sizable number of patients who currently have no approved treatment option. Jadeite's entrepreneurial,biotech approach makes them the right type of partner to successfully commercialize Bylvay in Japan," said Ron Cooper,President and Chief Executive Officer of Albireo. "The agreement allows for success of both companies,and we look forward to further collaboration with Jadeite."

Bylvay is the first drug approved in Europe for the treatment of all types of PFIC and in the U.S. for the treatment of pruritus in all types of PFIC. A potent,non-systemic ileal bile acid transport inhibitor (IBATi),Bylvay is administered as a once-daily capsule or opened and sprinkled onto soft foods. Bylvay is currently being evaluated in the ASSERT Phase 3 study for Alagille syndrome,the BOLD Phase 3 study for patients with biliary atresia and the ongoing PEDFIC 2 open-label trial for patients with PFIC.

"CBC remains steadfast in our commitment to widening access to medical care globally,and Jadeite is our cornerstone in Japan. The partnership with Albireo represents important progress toward that goal by expanding more treatment options,initially for children living with rare liver diseases in Japan," said Sean Cao,Managing Director of CBC Group. "By leveraging our extensive investor-operator experience in Asia,we will continue to partner with the world's top pharmaceutical companies and scientists and identify opportunities to broaden global reach for patients with unmet medical needs."

CBC,founded in 2014,is Asia's largest healthcare-dedicated investment firm,with US$4.6 billion AUM. Its portfolio has gained momentum in recent years by incubating cutting-edge biopharmaceutical companies in Asia and beyond. Jadeite is the first company to be incubated by CBC in Japan,following the success of its unique investor-operator approached in empowering Nasdaq-listed I-Mab Biopharma and Hong Kong-listed Everest Medicines.
