WILEX subsidiary Heidelberg Pharma signs license agreement for the
development of Antibody Targeted Amanitin Conjugates (ATACs) with Roche

Munich, Germany, 02 September 2013 - WILEX AG (ISIN DE0006614720 / WL6 /
FSE) today announced that its subsidiary Heidelberg Pharma GmbH, Ladenburg,
Germany, signed a license agreement with Roche (SIX: RO, ROG; OTCQX: RHHBY)
covering the development of a novel class of antibody drug conjugates
(ADCs) based on Heidelberg Pharma's patented technology to couple
α-Amanitin to antibodies. The license agreement covers initial joint
research to apply this technology to multiple Roche antibodies towards the
identification of development candidates with favourable efficacy/safety

Heidelberg Pharma will receive regular payments for granting access to its
technology and providing research services. Roche will subsequently have
the opportunity to exercise options for licenses to develop and market
selected Antibody Targeted Amanitin Conjugates (ATACs). Heidelberg Pharma
will manufacture these substances and receive customary upfront payments,
milestone payments and royalties for each development candidate selected
by Roche.

α-Amanitin is a bicyclic peptide naturally occurring in the green Death Cap
mushroom. It potently inhibits the biosynthesis of RNA, a mechanism which
is critical for the survival of cells. Accordingly, ATACs exhibit
comparable activity against proliferating and resting tumour cells. This
proliferation independent activity differentiates ATACs from other ADCs,
which preferentially target proliferating tumour cells. As an additional
advantage ATACs could offer a substantial capability to overcome the
resistance mechanisms which might limit the efficacy of other antibody drug
conjugates. The ATACs tested so far have shown strong anti-tumour activity
in several preclinical tumour models.

Dr Jan Schmidt-Brand, Managing Director of Heidelberg Pharma GmbH and Chief
Financial Officer of WILEX AG, commented: 'We are delighted about the
opportunity to collaborate with a company as renowned as Roche. This
cooperation is an important external validation of our technology. We will
use this cooperation to jointly explore and technically expand the
applicability of our technology to selected antibodies.'

Dr Klaus Bosslet, heading Roche Discovery Oncology in Penzberg, Germany,
added: 'We look forward to collaborating with Heidelberg Pharma to elect
and develop the most promising ATACs. Ultimately, these ATACs may provide
novel treatment options for cancer patients, whose tumours do not respond
to available cancer therapeutics.'
