Chris Cargill, President & CEO of Nxera Pharma, commented: “Our name change from Sosei Group to Nxera Pharma marks a pivotal moment in our Company’s journey. It follows the significant growth and development of the business, which has been accelerated through several key strategic acquisitions in recent years, including Heptares Therapeutics in 2015 and the Idorsia Pharmaceuticals Japan and Korea businesses in 2023. These acquisitions have transformed the business into an integrated, technology powered, commercial-stage biopharmaceutical company focused on accelerating the development of life-changing medicines for patients in Japan and globally, by investing in science and technology.

“The Company decided that now is the optimal time to unify the business under a new name and bold brand. The name ’Nxera’ derives from the words ‘Next’ and ‘Era’ and our new motto – ‘Our Life’s Work is Life Itself’ – expresses our determination to lead the next era of medicine, leveraging our industry leading NxWave™ platform to drive advancements in our core disease areas of neurology, GI and immunology, metabolic disorders and rare diseases, in pursuit of new medicines for patients.”

Shinichi Tamura, Chairman of Nxera Pharma, added: “When I founded Sosei in 1990, I had a clear vision to create Japan’s first global biotechnology champion. I am extremely proud of what we have achieved since then and truly excited about what we, as Nxera Pharma, can deliver in the future, to our patients, partners, employees and shareholders, as this vision becomes a reality.

“Our Company would not be where it is today without the dedication and effort of our truly international team, primarily in Japan and the UK, but also with key groups in South Korea and Switzerland. I would like to express my sincere gratitude to all the ambitious and highly talented people who have contributed to and shaped our journey, positioning Nxera Pharma at the forefront of the next generation of biopharmaceutical companies in Japan improving the health of patients globally.”
