Identifying deubiquitylating enzymes (DUBs) as targets for treating of platinum-resistant ovarian cancer

Novel therapies tailored for treatment of platinum-resistant ovarian cancer is an area of clear unmet need. Ovarian cancer is responsible for more deaths per year than any other cancer of the female reproductive system and developing drug resistance remains the main limitation of current chemotherapies. We propose an innovative approach to identifying novel drug targets for drug-resistant ovarian cancer that would exploit the very changes in the tumour that have led to the resistance. We propose to do this by screening all known human deubiquitylases (DUBs) – a novel, druggable class of enzymes – to identify innovative targets whose inhibition would selectively kill or re-sensitise drug-resistant ovarian tumours. The best validated targets will then enter the MISSION Therapeutics Ltd pipeline for further drug discovery efforts with a view to new, innovative and effective chemotherapies entering the clinic.
