DLA Piper advised IntraBio Inc. in connection with its entry into a definitive agreement to be acquired by Shionogi Inc., a subsidiary of Shionogi & Co., Ltd., in a transaction that includes US$2 billion in upfront cash consideration.
The proposed transaction is subject to customary closing conditions, including applicable regulatory approvals, and is anticipated to close in the fourth quarter of 2026.
IntraBio develops and commercializes therapies for neurodegenerative diseases. The acquisition would add AQNEURSA® (levacetylleucine), IntraBio’s approved treatment for certain manifestations of rare neurological diseases, to Shionogi’s portfolio and strengthen its rare disease capabilities.
The DLA Piper deal team was led by Partners Josh Seidenfeld, who leads the firm’s Northern California Corporate and Securities practice, Michael Patrone, and Philipp Tsukanov. They were supported by Rachel Myung, Matt Savoff, Kayleigh Nevin, Jason Parfet, and Ali Pontious (Corporate); Jason Veit (Employee Benefits and Executive Compensation); Lauren Murdza and Arthur Cohn (Life Sciences Licensing); Jae Kim and Christine Lentz (FDA); Victoria Lee and Marco Berrios (Intellectual Property); Georgia Jolink and Jessica Jackson (Labor and Employment); Neil Balmert and Kevin England (Tax); and Nicholas Klein (Global Trade and CFIUS).
