    February 27, 2012

Munich, Germany, 27 February 2012. WILEX AG (ISIN DE0006614720 / WL6 / FSE) today announced that the US Food and Drug Administration (FDA) approved the protocol amendment for the pivotal Phase III ARISER trial with RENCAREX® needed to cancel the interim analysis and perform the final analysis of disease free survival (DFS). Final DFS analysis and results are expected in Q4 2012; the study will continue as planned in order to assess overall survival

As announced in November 2011 the ARISER Independent Data Monitoring Committee had recommended cancelling the interim DFS analysis and performing the final DFS analysis instead. This recommendation was consistent with advice from the FDA and European regulatory authorities.

About RENCAREX® and the ARISER study
The drug candidate RENCAREX® is based on the antibody Girentuximab, which binds to the tumour-specific antigen CA IX an antigen that is overexpressed in clear cell renal cell carcinomas (ccRCC). The therapeutic antibody makes the tumour visible to the endogenous immune system and binds natural killer cells, which can destroy existing cancer cells. RENCAREX® should inhibit the further growth and recurrence of ccRCC a particularly aggressive type of cancer and kill cancer cells, thereby prolonging the disease-free survival of patients.
ARISER (Adjuvant RENCAREX Immunotherapy trial to Study Efficacy in non-metastasised Renal cell carcinoma) is an international, multicentre, randomised Phase III trial that examines the efficacy of the antibody RENCAREX® in comparison to placebo in the treatment of clear cell renal cell cancer patients following complete or partial surgical removal of the affected kidney in patients with no detectable metastases. The ARISER trial involves 864 patients, who received the study medication in once-weekly infusions over a period of 24 weeks. The last patient completed treatment in February 2009. Following the occurrence of the 100th relapse, an interim analysis for futility was carried out in late 2007. The IDMC recommended that the trial be continued because it will probably deliver a significant result.
WILEX has granted commercialisation rights for RENCAREX® for certain countries of Southern Europe to the Spanish pharmaceutical company Esteve and US commercialisation rights to the US-based company Prometheus.
