Advanced Proteome Therapeutics and Heidelberg Pharma Progress Collaborative Program

VANCOUVER, BC and LADENBURG, GERMANY--(Marketwired - January 08, 2018) - Advanced Proteome Therapeutics Corporation (APC), a therapeutics discovery and development company, and Heidelberg Pharma announced today advances in their collaborative activities. The companies have agreed to test the combination of APC's proprietary site-selective protein modification technology and Heidelberg Pharma's proprietary ATAC technology in order to generate superior cancer therapeutics.

Since the inception of the partnership, activities have been centered on antibody-amanitin conjugates that are produced using controlled conjugation methods and possess high target-specific cytotoxic potency. The companies have successfully demonstrated the generation of ATACs using APC's proprietary protein modification technology.

"In a first step, we have succeeded in producing ADCs that are sufficiently cytotoxic to target-expressing cancer cell lines to proceed to the next level of in vivo testing. Results obtained from this collaboration will help us to increase the efficacy of our ATACs", commented Professor Andreas Pahl, CSO of Heidelberg Pharma.

"We are delighted that the partnership with Heidelberg Pharma has generated positive results and look forward to continuing our work together, to the benefit of both companies", commented Randal Chase, CEO of Advanced Proteome Therapeutics.

APC's technology aims at the coupling of a cytotoxic payload site-selectively to an antibody of interest without the necessity of genetically engineering such antibody. This may lead to more homogeneous products with certain additional advantages such as an increase in stability in the circulation, fewer side effects and facilitating further pre-clinical and clinical drug development.

About Advanced Proteome Therapeutics

Advanced Proteome Therapeutics Corporation (APC) (TSX VENTURE: APC) (FRANKFURT: 0E8) is developing a proprietary technology to directly target cancerous tumors and avoid destroying normal cells. This type of agent is capable of greater potency, higher specificity, and lower toxicity than other therapies that can also attack healthy cells. Advanced Proteome is working to streamline the process by which these agents are prepared, which to date, has been extremely cumbersome, limiting their potential. www.advancedproteome.com
