Onxeo Strengthens Beleodaq® Patent Protection in the U.S. until 2027

PARIS & COPENHAGEN, Denmark--(BUSINESS WIRE)-- Regulatory News :

Onxeo SA (Paris:ONXEO) (NASDAQ OMX:ONXEO) (Euronext Paris, NASDAQ OMX Copenhagen
- ONXEO), an innovative company specialized in the development of drugs for
orphan oncology diseases, today announced that the U.S. Patent Office will grant
a new patent for Beleodaq® (Belinostat U.S. commercial name) on September 16th
2014.

In addition to the existing patent, covering the chemical structure of
Beleodaq®, this new patent also covers the formulation of the product,
strengthening and expanding significantly its industrial property protection
until October 2027 in the U.S.

Beleodaq® also benefits from the commercial exclusivity related to its orphan
status in the US.

Beleodaq® has obtained Marketing Authorization from the Food and Drug
Administration (FDA) for the treatment of patients with relapsed or refractory
peripheral T-cell lymphoma (R/R PTCL) in early July 2014. PTCL accounts for
around 10 to 15% of non-Hodgkin's lymphoma and its global incidence is estimated
at 12,000 cases each year.

“This new patent significantly increases the value of our product”, commented
Judith Greciet, CEO of Onxeo. “Indeed, it extends the period of market
exclusivity, and it will foster the initiation of other promising indications’
development with our U.S. partner Spectrum Pharmaceuticals”.
