Research at the University of Sheffield contributed to the development by GlaxoSmithKline (GSK) of a drug to treat Irritable Bowel Syndrome (IBS) that has transformed the lives of thousands of patients and generated significant revenue. The drug, alosetron, which blocks 5-HT3 receptors in the gastrointestinal tract, was approved by the Food and Drug Administration (US) (FDA) in 2000 and launched under the trade name Lotronex. It is currently the only drug on the market aimed specifically at the treatment of diarrheal IBS. Although GSK voluntarily withdrew the drug from the market following concerns over possible side effects, Lotronex was relaunched in 2004 following petition from IBS sufferers and user groups. The licence for Lotronex was sold in 2008 to Prometheus Laboratories, Inc. and annual sales of the drug now exceed $34 million. In 2011 Prometheus was bought by Nestle for an estimated $1.1billion. This case study has significant impact on commerce and health and welfare.
Imperial College research on the gut hormone, oxyntomodulin, showed it caused considerable weight loss in man. A powerful long acting analogue suitable for daily human administration (TKS1225) was developed. This was licensed by Imperial to a spinout, Thiakis Ltd, for successful human toxicity testing and then sold to Wyeth for $30 million initially and $120 million on meeting milestones. Wyeth Pharmaceuticals and the full legal agreement was subsequently acquired and developed by Pfizer in 2009.
Research led by Dr. Peter Richardson in the Department of Pharmacology led to the development of an A2A adenosine receptor antagonist (istradefylline) for the treatment of Parkinson's disease. In 2001, Dr Richardson founded the spin-out company Cambridge Biotechnology (CBT) to develop these drugs. A pH-sensitive adenosine A2A receptor agonist is now being developed for the treatment of neuropathic pain, with one product licensed for use in Japan in 2013 (Nouriast). Small-molecule leptin mimetics as potential anti-obesity drugs were also developed, initially by CBT and since 2009 by Astra Zeneca following acquisition of the research programme. CBT has undergone a number of high-value acquisitions, by Biovitrium, Proximagen, and most recently Upsher-Smith. It continues to operate as a wholly-owned subsidiary, employing 30-35 people from 2001 to the present.
Research conducted at the University of Bristol since the late 1990s has pioneered the development of over 60 chemical probes that are selective for individual ionotropic and metabotropic glutamate receptors. The development of these probes has led to numerous commercial impacts, including: the establishment of two companies, which both sold during the assessment period for a combined value of £85 million, and sales revenue for global providers of biochemicals. This research has also stimulated considerable industry investment in drug development.
Research by Professor Kevin Fone in the Neuroscience group has established and characterised rodent models of CNS disorders that have been instrumental in validating several 5-hydroxytryptamine (5-HT) receptors as therapeutic drug targets to treat learning and memory dysfunction in humans. Specifically, animal studies to validate the 5-HT6 receptor for cognitive impairment in Alzheimer's disease (AD), depression and schizophrenia have resulted in R&D investment in drug discovery programmes by several global pharmaceutical companies. Consequent advances in healthcare benefits (current and potential) are also summarised.
Original basic research on melatonin receptors undertaken at the Rowett Institute, University of Aberdeen, and funded by the Scottish Government, provided the opportunity for Servier pharmaceuticals to develop a new line of therapeutics for depression.
The company exploited Rowett know-how and invested in new research to develop a new line of compounds and to understand their structure-function relationships. This work enabled the development of melatonin analogues for clinical trials and ultimately led to the development of melatonin compounds for treatment of circadian related disorders.
One (S20098) was identified as having positive effects for disrupted circadian rhythms and beneficial outcomes for patients with depression. S20098 (also known as Agomelatine) was launched after EU authorization in 2009 as a novel anti-depressant drug called Valdoxan®. Today Valdoxan is an award winning anti-depressant drug recognised for its novel mechanism of action and few side effects. Valdoxan is the only anti-depressant drug to be brought to the market in the last 10 years. In summary, supported by investment from industry research undertaken at the University of Aberdeen contributed to the development of a novel antidepressant drug that provides a new clinical intervention with advantages over previously available antidepressants that will make a significant impact on the health and well-being of those afflicted by depression.
Research by the School of Pharmacy has underpinned the development of fluorescent ligand probes that have opened-up new pathways in drug discovery. These ligands have been commercialised through the formation of the spin-out company CellAura Technologies Ltd, and have been made globally available through a number of distributer agreements. Customers include pharmaceutical companies (e.g. Pfizer, AstraZeneca), drug discovery biotechs (e.g. Addex, Heptares) and drug discovery technology providers (e.g. CisBio). These ligands provide alternatives to the use of radio-ligands, giving more informative and safer solutions for industrial drug discovery. This has, for example, enabled: a new direction in G protein-coupled receptor research at Novartis Pharmaceuticals UK Ltd; validation of Promega Corporation's new drug-binding assay; and superior performance in the establishment of cell lines at inSCREENex GmbH.
