A new intervention has been developed and trialled in patient groups characterised by mucus obstruction of the airways. Outcomes for these patient groups have improved, and health service decisions have been informed by the underpinning research. A spin-out business, Ockham Biotech Ltd., was created and has generated overseas investment.
A novel mucolytic application and inhaled route of administration for heparin has provided a simple and cost-effective therapeutic means of relieving the symptoms of mucus obstruction in diseases including CF and COPD, which cost the NHS ~£600m and £1bn, pa, respectively.
Sustained research by the University of Oxford's Mahidol Oxford Tropical Medicine Research Unit in Thailand (MORU) has been the driving force behind the current World Health Organization recommendations for the management of acute and chronic infection in patients with melioidosis. This research has motivated improvements in treatments and provided new strategies to identify at-risk populations, enabling clinicians to make early diagnoses. Melioidosis is a major cause of severe illness in parts of Southeast Asia and there are increasing numbers of cases in India, China, and Brazil.
Research at Hull into hypersensitivity of the airways has provided novel insights into the epidemiology and causes of cough, and its burden on patients. This was achieved by the development of novel methodologies that allow the rigorous and objective testing of new and existing drugs. Patients benefit through the online provision of a diagnostic tool, and Proctor & Gamble have successfully exploited the cloned cell receptors in their drug development programme resulting in a new range of pharmaceuticals for cough. The work has underpinned the standardisation of cough challenge methodology through incorporation in national and international healthcare guidelines leading to a widespread improvement in patient treatment.
In 1994, Professor Barnes and colleagues at Imperial College showed that nitric oxide (NO) concentrations were increased in the breath of asthmatic patients compared to non-asthmatic controls and were reduced after treatment with inhaled steroids. They subsequently demonstrated that exhaled NO (FENO) could be reliably measured in the clinic, was correlated with eosinophilic airway inflammation in asthma, was increased with airway inflammation and decreased when asthma was controlled. Exhaled NO has subsequently been shown by many investigators to be a useful non-invasive biomarker of airway inflammation in asthma and to improve clinical management in selected patients. They demonstrated that nasal NO is very low in patients with primary ciliary dyskinesia and is now recommended worldwide as a diagnostic test for this disease as it is a much easier method than previously available tests.
Research led by University of Oxford scientists has resulted in widespread use of the humanised therapeutic antibody, Campath (alemtuzumab), in patients with chronic lymphocytic leukaemia (CLL). Licensed by both the European and American regulatory authorities in 2004 for the treatment of CLL, Campath is used as first-line treatment for patients with aggressive forms of the disease and following relapse. It can induce long-term clinical remission even in cases resistant to other drugs. Campath has now been used in approximately 15,000 patients, and has generated revenues of approximately £750 million from the licensed treatment of CLL.
The University of Oxford's International Subarachnoid Aneurysm Trial (ISAT) changed clinical practice worldwide by showing that endovascular coiling is a more effective and safer treatment than neurosurgery following subarachnoid haemorrhage, with fewer complications and improved quality of life. Subarachnoid haemorrhages account for 1 in 14 strokes and are caused by bleeding in and around the brain; approximately 85% occur when cerebral aneurysms rupture. ISAT was the first trial to compare neurosurgery, or neuroradiological endovascular coiling in patients with ruptured cerebral aneurysms causing acute subarachnoid haemorrhage.
Research at UCL firmly established tacrolimus as the optimal calcineurin inhibitor to use in immunosuppressive regimens following liver transplantation. Compared to ciclosporin its use improved graft survival by 6% and patient survival by 7%. Assuming 550 liver transplants per year in the UK since 2008, we can estimate that, with 90% of patients treated with tacrolimus and 10% ciclosporin, tacrolimus-based immunosuppression has resulted in 165 grafts and 192 lives being saved during the period 2008-13.
Research at the University of Manchester (UoM) has led a step-change in respiratory care for airway disease from oral to novel inhaled therapies targeted at asthma and chronic obstructive pulmonary disease (COPD) patients worldwide. UoM researchers carried out >250 studies, partnered industry to deliver >15 new inhaled drug formulations to market and were the first to test novel CFC-free inhalers. UoM led the development of global guidelines that influence better diagnosis and management of airways diseases. Through leadership within the Montreal Protocol since 1995, UoM researchers coordinated the safe global transition to CFC-free inhalers for ~200m patients with asthma and COPD, whilst protecting the ozone layer and climate.
The epilepsy research group at the University of Liverpool (UoL) has undertaken a programme of work assessing treatment outcomes associated with antiepileptic drug treatment in patients with epilepsy. This includes two large pragmatic trials in patients with first seizures and newly diagnosed epilepsy, and cohort studies assessing malformations and cognitive development in children exposed to antiepileptic drugs in utero, and the work of the Cochrane Epilepsy Group.
This work has influenced prescribing in the UK and worldwide through the following impacts:
Heaney's research at Queen's University Belfast on difficult-to-treat asthma (or simply "difficult asthma"— DA) patients has led to changes in clinical management guidelines and a drive to co-ordinate and commission specialist services nationally for DA patients. It has also led to the establishment of a UK Multi-centre National Clinical Network and Patient Registry (Centres listed in Section 5). DA patients have persistent symptoms and frequent exacerbations despite being on high dose asthma therapy. DA patients (10% of the asthmatic population) have significant morbidity and carry a high risk of asthma death. Their clinical assessment has been optimised to ensure proper management of both their asthma and non-asthma related conditions.
