About Summit plc
Summit plc is a leading UK biotechnology company that discovers and develops proprietary new drugs. The Company's internal drug development programmes are underpinned by its advanced carbohydrate chemistry and zebrafish drug screening technology platforms, which it also provides on a collaborative or fee-for-service basis to the pharmaceutical industry.
Summit plc has a broad range of drug discovery programmes in the clinical, pre-clinical and discovery stages of development, which target serious diseases with a high unmet medical need. These therapeutic areas include neurological disorders, anti-infectives, ophthalmic diseases and oncology.
Summit plc's in-house drug development capabilities combine world-class expertise in both carbohydrate chemistry with high-volume, high-content screening using its proprietary zebrafish technologies. These whole organism screens have the potential to dramatically decrease the time and cost of drug discovery and development by delivering data that are highly predictive of the efficacy and toxicity of potential drug compounds in humans.
