Uppsala, Sweden – August 6, 2014 – Orexo AB (publ) announces today that
Boehringer Ingelheim has decided to return the OX-MPI project to Orexo. The
project aims to develop products based on specific inhibition of prostaglandin
E2 (PGE2) in different disease conditions. Boehringer Ingelheim has since 2005
been responsible for all research and development within the OX-MPI project.

Orexo is evaluating the results from Boehringer Ingelheim and when this is
completed will make a final decision on the potential to continue the project
with a new external partner. The return of OX-MPI from Boehringer Ingelheim has
no direct impact on the financial position of Orexo. The OX‑MPI project is
associated with an intangible fixed asset of MSEK 62 from the acquisition of
Biolipox and this asset will be impaired if a final decision is taken to
discontinue the project.
