Beleodaq® (belinostat)

• Grant of US conditional marketing authorization of Beleodaq® for the treatment of patients with relapsed or refractory peripheral T-cell lymphoma (PTCL). This approval has triggered a $25 million milestone payment from American partner Spectrum Pharmaceuticals, to be received by year-end by the company.

Governance

Now that the merger process is fully completed, Mr. Per Samuelsson and Dr. Bo Jesper Hansen are leaving the Board as of November 7th. Dr Hansen has brought to the Board's attention a newly emerged potential conflict of interest, which requires his stepping down in line with good governance practices; Mr. Per Samuelsson has asked to be relieved from the Board to allow more time to other assignments.

In parallel, the company board of Directors will evolve to add new expertise, especially to reinforce its scientific skills in line with its ambition to become a global leader in Orphan Oncology.

Perspectives and clinical challenges

Validive®: Based on the positive phase II results, the company will initiate the preparation of a phase III trial to evaluate Validive® efficacy. Thanks to its fast track status in the US, discussions with FDA will be eased and the company plans to submit this new study in the course of 2015.

Beleodaq®: Following the conditional marketing authorization in 2nd line PTCL, a phase III trial will be initiated together with Spectrum Pharmaceuticals to confirm Beleodaq® efficacy and safety in PTCL 1st line, both in the US and Europe. Other indications are also reviewed by the company and Spectrum Pharmaceuticals to further develop Beleodaq®’s potential.

Livatag®: As planned, the fifth DSMB will be held Q4 2014, to evaluate the tolerance of Livatag® in nearly 35% of planned patients randomized. As of now, DMSB has each time unanimously recommended continuing the study without modification, based on positive assessment of Livatag® safety data.

“The first months of Onxeo are marked by very successful and crucial achievements on key products. Beleodaq® has been registered and launched on the U.S. market, Validive® phase II has shown positive results allowing its passage into phase III. Next critical steps in the coming months will be to design the most effective development plans for these two products”. declares Judith Greciet, CEO of Onxeo

“With a reinforced cash position, a strengthen team thanks to the merger with Topotarget and enlarged promising pipeline, Onxeo has reinforced during the course of the past months its postion to become a major player in Orphan oncology ”, she continues.
