WILEX AG announces discontinuation of collaboration between its subsidiary Heidelberg Pharma and Roche

Munich, 12 August 2015 - WILEX AG (ISIN DE000A11QVV0 / WL6 / FSE) was informed today that Roche is discontinuing its partnership with the WILEX subsidiary Heidelberg Pharma GmbH with respect to their collaboration in the field of antibody-targeted amanitin conjugates (ATACs). The licence agreement was signed in 2013 and expanded in October 2014.

Roche has recently increased the focus of its oncology research strategy on cancer immunotherapies and deprioritised other internal and external oncology research programmes accordingly. Affected by this deprioritisation are the collaborative research efforts with Heidelberg Pharma, which in recent years have progressed well, on schedule, and in a mutually satisfactory manner.

Updated financial outlook for 2015

As a consequence of the termination of existing collaborative efforts to develop and identify novel antibody-targeted amanitin conjugates (ATACs), WILEX AG revised today its financial outlook for the current financial year. Due to lower sales revenues WILEX's cash reach is reduced from the end of the second quarter 2016 to the first quarter of 2016.
