The Independent Data Monitoring Committee today informed WILEX that the Phase III interim analysis for futility was positive

MUNICH, Germany | December 13, 2007 | The Munich-based biopharmaceutical company WILEX AG (ISIN DE0006614720 / Frankfurt Stock Exchange / Prime Standard) announced that the Independent Data Monitoring Committee (IDMC) recommended on the basis of the interim analysis for futility for the Phase III ARISER trial to continue the study as planned. The analysis, which was performed after 100 patients relapsed, showed that the trial will probably deliver a significant result. Moreover the safety and tolerance of RENCAREX® had again been confirmed in a safety review by the IDMC in October 2007.

The IDMC evaluated the data with respect to the time between randomisation and relapse of 100 patients in comparision to time between randomisation and last computer tomography of all other patients randomised in the study at the time of analysis and which had not relapsed. No-one outside the independent Committee has had access to the data.

Dr. Paul Bevan, Head of Research and Development and member of the executive management board of WILEX, commented: “The positive result of the interim analysis for futility further supports our assumptions of the positive progress of the ARISER trial. Therefore, as well as continuing clinical development we will now accelerate the commercialisation of the product. “

About the ARISER study

The international, multicentre, randomised trial, called ARISER (Adjuvant Rencarex Immunotherapy trial to Study Efficacy in non-metastasized Renal cell carcinoma), examines the efficacy of the antibody RENCAREX® in comparison to placebo for the treatment of clear cell renal cell cancer patients after complete or partial surgical removal of the affected kidney in patients with no detectable metastases. This cancer belongs to one of the particularly aggressive indications. RENCAREX® aims to inhibit these malignant kidney tumours from further growth and recurrence and to help to destroy cancer cells and thereby prolong the disease-free survival of patients.

About the IDMC

The Independent Data Monitoring Committee (IDMC) consists of independent oncologists, urologists and a statistician and has the responsibility to check the data of the ARISER trial at regular intervals and recommends to WILEX, to modify, to discontinue or to continue the trial as planned. The members of the IDMC do not participate in the trial.
