WILEX AG: Final Phase II data of Mesupron confirm impressive increase in overall survival of patients with pancreatic cancer

Munich, Germany, 3 May 2010. The biopharmaceutical company WILEX AG (ISIN DE0006614720 /Frankfurt Stock Exchange/Prime Standard) today announced that the clinical Phase II combination trial with the oral drug candidate MESUPRON® in pancreatic cancer patients has been completed successfully. Final analysis confirms preliminary data published in September 2009, for example with regard to improvement in tumour response and increase in overall survival.

The results will be published at the annual meeting of the American Society of Clinical Oncology (ASCO), which will take place from June 4 to 8, 2010 in Chicago, USA. ASCO is the most important worldwide clinical conference for oncology experts.

Prof Volker Heinemann, Medical Centre Grosshadern, University Munich, and Principal Investigator, said: “The results regarding tumour response and overall survival are impressive and signify important progress in the treatment of cancer patients with a urgently needed, innovative and well tolerated therapeutic approach. Doctors and patients eagerly await further developments with MESUPRON®.”

Information regarding MESUPRON® and the uPA programme

The aim of MESUPRON® is to inhibit the Urokinase Plasminogen Activator enzyme system (uPA), which plays a key role in the growth and spread of various malignant tumours. This was established on the basis of a meta analysis of 18 different European studies on the length of survival in relation to the uPA content in the tumour involving a total of more than 8,300 patients. The tumour-associated proteolytic factor uPA and its inhibitor PAI-1 are the only tumour biological factors which have provided the highest level of evidence (LOE1) in terms of their prognostic and predictive significance.

MESUPRON® is the first uPA inhibitor worldwide in clinical development and which has shown positive activity in cancer patients in a Phase II trial. MESUPRON® could have the potential to treat cancer like a chronic disease in a long-term therapy with low side effects.

Information on the trial

In the completed Phase II trial, patients with locally advanced, inoperable, non-metastatic pancreatic cancer were treated with MESUPRON® together with the chemotherapeutic Gemcitabine (Gemzar®, Eli Lilly and Company, USA). The study is a randomised, open label, three-arm trial. Patients were administered either Gemcitabine alone or in combination with a daily oral dose of 200 mg or 400 mg MESUPRON® respectively until progression. As previously demonstrated in the eight completed Phase I trials, MESUPRON® proved to be safe and well tolerated.

In addition to the pancreatic cancer trial the Company is conducting a Phase II trial in which HER2 receptor negative breast cancer patients are treated with MESUPRON® in combination with the chemotherapeutic agent Capecitabine (Xeloda®, Hoffmann La Roche AG, Switzerland).
