Munich, Germany / Vancouver, Canada, 14 June 2016 – WILEX AG (ISIN DE000A11QVV0 / WL6 / FSE) and the Advanced Proteome Therapeutics Corporation, (TSX:V APC) today announced that Heidelberg Pharma GmbH, a subsidiary of WILEX AG, entered into a partnership with the Canadian APC to create a new generation of antibody-drug conjugates (ADCs).

The companies will test combining APC’s proprietary site-specific protein modification technology and Heidelberg Pharma’s proprietary ATAC technology in order to generate a cancer therapeutic with enhanced characteristics that can also serve as a prototype for a new generation of antibody-drug conjugates (ADCs).

“We are delighted to work with APC on the next generation of cancer therapies using APC´s approach which might broaden the scope of coupling methods for our ATAC technology”, commented Andreas Pahl, CSO of WILEX AG and Heidelberg Pharma GmbH.

Allen Krantz, Founder and CEO of APC added: “The application of our site-specific technology to Heidelberg Pharma’s novel payload has the potential to result in examples of more homogeneous and more effective ADCs than have been available to date, while giving rise to a new type of antibody-drug conjugate with substantial appeal to the industry.”

Demonstrable success in the milestone-driven research, using a combination of both technologies, provides a basis for the companies to work towards taking an eligible therapeutic product candidate into clinical studies.

Heidelberg Pharma’s aim and expertise is in making the compound Amanitin available as a new cancer therapy. Amanitin has a unique biological mode of action which could be used as the basis for developing highly effective, innovative drugs. Selective treatment of tumours using cytotoxic payloads like Amanitin via specific antibody-drug conjugates could enable much more effective therapy than existing drugs. Heidelberg Pharma is building a pipeline of ATAC product development candidates alone or with partners.
