About MISSION Therapeutics

Founded in 2011, MISSION Therapeutics builds on the research of Professor Steve Jackson FRS, who holds the Frederick James Quick Chair of Biology at the University of Cambridge, by exploiting the new and extensive research emerging on the ubiquitin pathways that control cellular responses to DNA damage.

MISSION has established a broad platform of technologies for the discovery and preclinical development of first-in-class modulators of ubiquitin pathway enzymes involved in cancer and other diseases. The Company is developing drugs to inhibit the proliferation of tumour cells, exploiting certain properties of specific DUBs, such as their oncogene status or association with synthetic lethality, the latter now a clinically-proven mechanism for selectively killing tumour cells.

The Company has received £27 million in venture capital from a blue chip syndicate comprising institutional (Sofinnova Partners, Imperial Innovations) and corporate (SR One, Roche Venture Fund and Pfizer) investors and is based at the Babraham Research Campus, south of Cambridge.
