A first-in-class anticancer agent discovered in Thurston's laboratory at the University of Portsmouth in the 1990s has been commercially developed and clinically evaluated over the last two decades. SJG-136 was successful in Phase I clinical trials and is completing Phase II clinical trials for the treatment of ovarian cancer and leukaemia, where significant patient benefit is observed. Related molecules based on this parent compound are in drug programmes being undertaken by Seattle Genetics Inc. and Genentech Inc., leading to additional clinical trials. A spin-out company, Spirogen Ltd, was established in 2000 to commercialise the intellectual property generated from the underpinning research, and the company has recently been sold to AstraZeneca for $200m.
Researchers at the University of Sheffield developed a novel tailored therapy for some forms of breast cancer. This was the first example of the selective killing of a tumour using an inhibitor of a DNA repair enzyme (PARP) to induce synthetic lethality, heralding an era of personalised cancer therapy. The discovery was patent protected and development rights sold to Astra-Zeneca who undertook successful phase I and II clinical trials. Disclosure of the findings stimulated intense investment in research and development and has revolutionised approaches to cancer therapy. There are now eight PARP inhibitors in phase I to III clinical trials (92 currently listed involving several leading pharmaceutical companies and thousands of patients) targeting a wide range of tumour types.
Through their study of DNA polymerases from organisms of the domain archaea, researchers at Newcastle University and University College London identified the mechanism by which these organisms avoid potentially damaging mutations in their DNA. As a consequence of this work they invented a novel genetically-engineered DNA polymerase. This enzyme has been patented and is the world's only high-fidelity, proofreading DNA polymerase that efficiently reads through uracil in the polymerase chain reaction (PCR). PCR is a very widely used technique in biomedical research. An international bioscience company [Text removed for publication, EV d] signed a licensing agreement with Newcastle University in 2008 to market the enzyme, and total sales since 2008 exceed [Text removed for publication, EV d]. Further commercial exploitation has begun through licensing agreements with other major companies.
A novel test for prostate cancer was developed from research in mitochondrial genetics conducted at Newcastle University. The Prostate Core Mitomic Test was the first of its kind and is now commercially available in North America. It provides molecular evidence to confirm conventional pathology results showing that men identified as being at risk of prostate cancer are, at the time of examination, free of disease. This is an important patient benefit, as conventional pathology has a 30% chance of missing prostate cancer. The Mitomic test obviates the short-term need for a follow-up biopsy, which is an invasive and very uncomfortable procedure. It is also capable of identifying some men at high risk of having prostate cancer that conventional pathology would miss. The test was introduced to the American market in June 2011 and has generated a multi-million dollar investment and turnover.
High-throughput genotyping has revolutionised the genome-wide search for associations between genetic variants and disease. Professor Sir Edwin Southern of the University of Oxford's Biochemistry Department invented the highly cost-effective array-based method of analysing genetic variation based on hybridisation between probes and samples on glass slides or `chips'. The spin-out company Oxford Gene Technology (OGT) founded by Southern in 1995 licenses the patent to manufacturers of `single nucleotide polymorphism (SNP) chips', including Illumina and Agilent, a global business exceeding $500M per year. Southern has continued to refine and extend this technology to increase its speed, efficiency and cost-effectiveness. This revolutionary technology has widespread applications such as prediction of individual risk, development of new drugs, provision of personalised treatments, and increased cost-effectiveness of clinical trials. Licence revenues fund R&D within OGT, and endow charitable trusts supporting primary school science education in the UK and crop improvement in the developing world.
Impact on commerce: A patented technique for separating methylated and non-methylated DNA has been licensed and a kit brought to market, along with other commercial reagent licenses.
Impact on health and welfare: The demonstration that two mechanisms of epigenetic gene regulation, DNA methylation and histone acetylation, are linked, has led to trials of separate drugs known to affect each mechanism as a combined treatment for high-risk patients with myelodysplastic syndromes (MDS).
Beneficiaries: Companies have gained commercial benefit from licensing UoE IP to market products. High-risk MDS patients will benefit from improved treatment.
Significance and Reach: Commercial earnings across 4 companies from international sales in the period estimated at over [text removed for publication], mainly since 2010. Commercial significance includes the first commercially-available technique for separating methylated and non-methylated DNA.
The incidence of MDS is estimated at 3-4 cases diagnosed annually per 100,000 of the population in Europe (an estimated 26,000 individuals) and up to 20,000 new diagnoses per year in the USA. Incidence increases with age — up to 15 new cases annually per 100,000 in individuals aged over 70 years. MDS occurrence is increasing as the age of the population increases, so the significance of new therapies is high.
Attribution: All research was led by Adrian Bird at UoE. Reik (Babraham Institute) contributed to development of one of the licensed antibodies.
This case study describes both economic and healthcare benefits that have resulted from a new DNA (gene) sequencing technique known as SOLiD sequencing. Through the 1990s until the present, Cosstick (University of Liverpool since 1984) has both developed the synthesis and studied the properties of chemically modified DNA in which a single oxygen atom is replaced by sulfur; we have termed this a 3'-phosphorothiolate (3'-sp) modification. Chemically prepared DNA containing the 3'-sp modification is a key enabling component of the Applied Biosystems SOLiD DNA sequencing instrument which is able to produce extremely rapid, cost-effective and exceptionally accurate DNA sequence information. The impact of this very powerful sequencing technology extends beyond economic benefits as it has many healthcare applications which have impacted medical practice.
Newcastle research selected the DNA repair enzyme poly(ADP-ribose) polymerase (PARP) as a promising target for cancer therapy. The first-in-class PARP inhibitor, rucaparib, was developed at Newcastle, in collaboration with Cancer Research UK and Agouron Pharmaceuticals, and subsequently became the first PARP inhibitor to be used to treat a cancer patient in a clinical trial. Currently, at least 8 PARP inhibitors are being developed and major pharmaceutical companies have to date invested around $385 million in clinical trials, and over 7,000 patients worldwide have been treated with PARP inhibitors in trials since 2008, demonstrating the importance of basic and translational research in universities to drug discovery by pharmaceutical companies.
Hagan Bayley's research on nanopore sensing for DNA sequencing at the University of Oxford led to the formation of the spin-out company Oxford Nanopore Technologies Ltd (ONT) in 2005. Since 2008, ONT has raised £ 97.8M to support research and product development. This level of investment arises as a direct result of the pioneering technology ONT has developed, based on research in the UOA, which has the potential to revolutionise DNA sequencing and other single molecule analyses. ONT currently employs 145 people, nearly six times as many as in 2008, and was recently valued at $ 2 billion. Evidence from ONT was used in a 2009 House of Lords report on genomic medicine, demonstrating ONT's position at the forefront of this new technology.
The Caldecott/Jeggo/O'Driscoll laboratories have identified human genetic diseases that are caused by defects in genes involved in DNA strand-break repair. Many of these diseases are associated with neurological pathologies such as cerebellar ataxia (resulting in poor balance, movement control, and patients often being wheelchair bound), microcephaly (smaller-than-normal head circumference), and developmental delay. The Caldecott/Jeggo/O'Driscoll laboratories have engaged in identifying/diagnosing patients with such diseases as a service to clinicians/clinical geneticists in the UK National Health Service (NHS) and worldwide. Since 2008, these laboratories have identified the underlying genetic defect in more than 150 patients with a range of hereditary DNA damage-related disorders. In particular, these laboratories have diagnosed patients with genetic defects in the DNA damage response genes Lig4, NHEJ1-XLF, DCLRE1C-Artemis, PRKDC-DNA-PKcs, PCNT, ORC1, ATRIP, ATR, and TDP2. These diagnoses benefit both the clinical geneticist and the patient; identifying not only the cause of the patient's disease but also enabling better disease management. For example, if not first diagnosed, standard chemotherapeutic regimes can be fatal in cancer patients who harbour homozygous TDP2 mutations, and standard conditioning regimes used during bone-marrow transplantation can be fatal in LIG4 Syndrome patients. These diagnoses can therefore translate into increased patient survival.
