  · Onxeo acquires first-in-class, signal-interfering DNA molecule based on one
of the most promising new approaches in cancer treatment
  · Acquisition expands Company’s R&D pipeline and opens new opportunities in
orphan oncology indications
  · Further development of Validive® to be conducted in partnership
PARIS & COPENHAGEN, Denmark--(BUSINESS WIRE (http://www.businesswire.com/))--
Regulatory News:

Onxeo S.A. (Paris:ONXEO) (NASDAQ OMX:ONXEO), an innovative company specializing
in the development of orphan oncology therapeutics, today announced that it has
reached an agreement to acquire DNA Therapeutics, a privately-held, clinical
-stage biopharmaceutical company, for its signal-interfering DNA (siDNA) repair
technology, which is directed at overcoming cancer resistance mechanisms, and
includes lead product candidate DT01. The acquisition, which is subject to
customary closing conditions, is expected to close by the end of March 2016.

The acquisition of DNA Therapeutics continues to demonstrate Onxeo’s commitment
to developing novel orphan oncology drugs that position the Company at the
forefront of scientific research for rare cancers with high, unmet medical
needs, and have the potential to generate significant value for the Company and
its stakeholders by opening other indications and markets.

Under the terms of the agreement, Onxeo is acquiring DNA Therapeutics for an
upfront payment of €1.7 million in common shares at deal closing. Additional
payment will come in the form of milestones including €1 million in cash or in
ONXEO shares, at ONXEO’s sole discretion, upon successful initiation of a Phase
II trial in a selected indication as well as royalty payments on future
commercial sales, up to €25 million per indication developed and approved.

In conjunction with the transaction, in parallel with the contribution in kind,
a large part of DNA Therapeutics’ historical shareholders have agreed to invest
€1 million in cash in Onxeo shares, showing their full support to Onxeo to take
over the development of the siDNA technology.

The signal-interfering DNA (siDNA) innovation
Through DNA Therapeutics, Onxeo is acquiring a first-in-class clinical signal
-interfering DNA (siDNA) molecule breaking the cycle of tumor DNA repair while
sparing healthy cells. The siDNA technology offers a potential new treatment
option for patients suffering from various types of cancer.

A first-in-human Phase 1/2a trial performed in metastatic melanoma demonstrated
that siDNA molecules showed good tolerance and safety when administered intra
-tumorally and subcutaneously around the tumors. Onxeo now plans to initate the
development of this first-in-class product by the systemic route, and to assess
their safety and tolerance in monotherapy and in combination with other DNA
-damaging agents in various solid tumors. This clinical development will be
implemented after first optimizing the manufacturing process, set to start as
soon as the deal closes.

Judith Greciet, CEO of Onxeo, commented: “The acquisition of DNA Therapeutics
and its siDNA technology represents a significant milestone for Onxeo. We are
excited about this opportunity, which, based on its differentiated mechanism of
action to fight cancer, will be significant in strengthening the level of
innovation in our orphan oncology portfolio and instrumental in delivering value
for our shareholders. The development of new agents specifically targeting DNA
repair while sparing healthy tissues is imperative in the treatment of many
solid tumors. Based on preclinical findings, we plan to evaluate the product in
orphan oncology indications where a systemic application is suitable and for
which there is significant unmet need, for example triple-negative breast cancer
and platinum-resistant ovarian cancer”.

Update on Validive® further steps
Over the course of 2015, Onxeo has continued to advance the clinical development
of Validive® and notably its validation by the US and European regulatory
agencies. Despite recognition from both agencies of Validive®’s interest and
value to patients, these discussions have confirmed that two Phase 3 clinical
trials will be required for registration in the US, which makes the further
clinical program significantly longer and more costly than expected. Therefore,
the Company has decided it is in the best interest of its shareholders to move
forward with this Phase 3 program only with the support of a partner. While
actively seeking for such collaboration, Onxeo will continue to promote the
scientific value of Validive® through presentations at meetings.

“Validive® remains a key asset in our orphan oncology pipeline. We have
successfully developed the product to date and it is ready to enter Phase 3 as
soon as we find the appropriate partner,” commented Judith Greciet. “We are
particularly excited about the acquisition of DNA Therapeutics and its first-in
-class product-candidate which largely complements our core expertise and
scientific ambitions. We believe it will be a tremendous addition to our
pipeline, creating sound opportunity for short-to-long term milestones, adding
value for our shareholders and bringing potentially new treatment options to
patients with rare cancers.”

About DNA repair
Biological responses to DNA damage and approaches to prevent the repair
mechanisms allowing cancer cells to escape treatments have been identified as
one of the most promising new avenues in cancer treatment. Most therapies
against cancer induce DNA damage to tumor cells. DNA damage can also occur
spontaneously in certain types of genetically unstable cancers. Yet cancer cells
have the ability to recognize DNA damage and activate multiple DNA repair
pathways or proteins to survive damages. These DNA repair processes contribute
to cancer aggressiveness and resistance.

About the signal-interfering DNA (siDNA) technology
The siDNA technology developed by DNA Therapeutics, and acquired by Onxeo,
breaks the cycle of cancer DNA repair activities by interfering at the core of
DNA damage and interfering with multiple repair pathways, while sparing healthy
cells. The technology, known as Dbait, was invented by Marie Dutreix, Research
Director at The French National Centre for Scientific Research (CNRS), and Jian
-Sheng Sun, Professor at The French National Museum of Natural History (Museum
National d'Histoire Naturelle) in Paris, and further developed in Dr. Dutreix’s
lab at Institut Curie. DNA Therapeutics was formed as a spin-out of the Institut
Curie and three other French academic institutions.

The siDNA molecule is a short double-stranded DNA molecule that acts as a decoy,
providing a false DNA break signal to attract DNA repair proteins which prevents
the recruitment of repair enzymes to the site of actual DNA damage. Cancer cells
do not have the ability to stop division in the face of DNA damage; they will
continue dividing with the damaged DNA and therefore die. Healthy cells, on the
other hand, will halt cell division until the compound is no longer present and
damaged DNA can be repaired.

In a variety of preclinical animal models, the siDNA molecule demonstrated an
increase in the efficacy of radiotherapy1, radiofrequency ablation2, and
chemotherapy3, and has not lead to toxicity with repeated cycles of treatment,
making it a promising candidate for both monotherapy and combination therapy. A
first-in-human Phase 1/2a trial, “DNA Repair Inhibitor & Irradiation on
Melanoma” (DRIIM; NCT01469455), in patients with metastatic melanoma
demonstrated the safety of local administration of the product. Additionally, no
maximum-tolerated dose (MTD) was identified and the product showed excellent
tumor response correlated with systemic exposure.
