WILEX successfully completed Phase I study with the MEK inhibitor WX-554 

Munich, Germany, 17 June 2010. WILEX AG (ISIN DE0006614720 / WL6 /
Frankfurt Stock Exchange) successfully completed a Phase I dose escalation
study with the MEK inhibitor WX-554 demonstrating for the first time WX-554
activity in humans.

The trial aimed to determine safety, tolerance and the optimal biological
dose for the inhibition of the MEK system by WX-554. The study, which was
conducted in Germany, tested five increasing dose levels, each administered
once by a 15 min infusion of WX-554 in five healthy male volunteers.

In addition to safety and tolerance, the pharmacokinetic and
pharmacodynamic properties of the MEK inhibitor were also investigated. The
substance was safe and well tolerated in the 25 healthy volunteers. The MEK
signal transduction pathway was inhibited in a dose-dependent matter
reaching complete inhibition at 1 mg/kg body weight.

Dr. Paul Bevan, Head of Research and Development and member of the
Executive Management Board of WILEX AG, commented: 'We are delighted with
the positive results of WX-554 in this study. With it we have a further
product in our clinical pipeline which, due to its mechanism of action,
could be used in many oncological indications. We will now initiate the
further development of this promising agent with the clinical testing of an
oral formulation.'

About WX-554
The orally available, small-molecule MEK inhibitor is one of five oncology
preclinical programmes obtained under the strategic alliance agreed with
UCB in January 2009. Mitogen activated protein kinase (MEK) has been shown
to play a central role in signal transduction. MEK has been linked to a
multitude of biological processes such as cell division, cell
differentiation and cell death. The MEK signalling pathway is over
expressed in more than 30% of cancers, resulting in uncontrolled cell
growth and proliferation.

the Frankfurt Stock Exchange at the Regulated Market / Prime Standard.
WILEX's mission is to develop drugs with a low side effect profile and
targeted treatment of different types of cancer as well as diagnostic
agents for specific detection of tumours. The Company's product candidates
are based on antibodies and small molecules. WILEX has an attractive
product pipeline which includes both drug and diagnostic candidates: A
pivotal Phase III study with REDECTANE(R) has been completed and positive
data published. RENCAREX(R) is undergoing a Phase III registration trial.
Positive MESUPRON(R) Phase II data in the indication pancreatic cancer have
been published and another Phase II trial in breast cancer is ongoing. A
further oncology project (PI3K inhibitor WX-037) is in preclinical
development and three antibody programmes are in research. WILEX aims
within a few years to be able to finance its research and development
programmes from its operating cash flow. Website: http://www.WILEX.com,
