Biomedical devices that need to be implanted into the body typically experience the so-called foreign-body reaction: proteins adhere to the surface of the devices, leading to rapid loss of function and, eventually, to a requirement for replacing the device. Between October 2006 and September 2011, The University of Reading, in collaboration with the UK SME BioInteractions Ltd., developed and evaluated a range of new polymers for coating implantable biomedical devices, especially coronary stents and catheters. The result was a coating system that can deliver a drug controllably over a pre-defined period, leading to the commercial biomaterials platforms AdaptTM and AssistTM. This work resulted in capital investment by Biointeractions Ltd and a substantial increase in their research staffing.
Research by the School of Pharmacy played a key role in the 2008 regulatory approval of Janssen Pharmaceutica's HIV drug Intelence®. As a poorly soluble drug, Intelence® required specialist formulation and was the first formulation of its type to be approved by the FDA and EMA. Intelence® offers significantly improved clinical outcomes due to its efficacy in patients with HIV resistance. Global Intelence® sales in 2012 were $349M, with additional not-for-profit supplies to resource-limited countries. As a result of this landmark regulatory approval formulation development strategies at Janssen were adapted enabling a further poorly soluble drug to reach the market. Telaprevir, a second-generation Hepatitis C treatment (marketed as Incivek®, Incivo® & Telavic®), gained global regulatory approval in 2011. 2012 sales exceeded $1bn in the US alone.
Innovative formulation science to create and develop the commercially successful PowderHale® technology was undertaken within the Department of Pharmacy & Pharmacology at the University of Bath, and subsequently by Vectura. This has directly provided the basis for novel, potentially life-saving treatments for chronic obstructive pulmonary disease (COPD). Seebri® Breezhaler® and Ultibro® Breezhaler® are once-daily, maintenance bronchodilators for the relief of various symptoms due to airways obstruction caused by COPD. Seebri® Breezhaler® was approved in the EU and Japan at the end of 2012 and has now been launched by Novartis. Ultibro® Breezhaler® a first-in-class combination bronchodilator was approved in Japan and the EU in September 2013. Under the terms of the licence agreement with Novartis concerning these products, Vectura has already received $52.5M with an additional >$100M anticipated upon achievement of regulatory and commercialisation targets. These medicines are major advances to treat and manage a disease that, according to the WHO, affects an estimated 210 million people worldwide and was the third leading cause of death in the developed world in 2012.
Research at the University of Sheffield developed pharmacokinetic tools that enable prediction of drug absorption, distribution, metabolism and excretion, and potential drug-drug interactions. In 2001 the University created a spinout company, Simcyp Ltd, to commercialise the technology. The impacts are:
Labelled compounds form an essential part of drug discovery and development within the pharmaceutical industry. Novel iridium catalysts, developed by Kerr at WestCHEM since 2008, have introduced a step-change in the ability to label pharmaceutical candidate compounds with radioactive (tritium) or non-radioactive (deuterium) isotopes.
The catalysts are applicable to specific types of compounds that comprise approximately one-third of all drug candidates. Advantages of the catalysts include greater efficacy (less catalyst needed and higher yield of labelled product, giving cost savings), greater speed (efficiency savings), and a significant decrease in radioactive waste compared with previous methods (environmental and safety benefits).
Even since 2008, their adoption within the pharmaceutical industry has been extremely rapid; e.g., the multinational pharmaceutical company AstraZeneca now applies the Kerr methodology to 90% of their relevant candidate compounds. Additional impact has been achieved by Strem Chemicals who have been manufacturing and marketing the catalysts worldwide since October 2012. Even in that very short period, multiple sales have been made on three continents providing economic benefit to the company.
A new, more structured way of assessing the various harms done to individuals, families, communities and wider society by a range of legal and illegal drugs was first articulated by Professor David Nutt and colleagues at the University of Bristol. The "rational scale" they developed in the light of their research has stimulated extensive policy debate and informed drug classification in the UK and overseas. The research underpinning the scale has been disseminated through numerous public lectures and discussions and has stimulated worldwide media coverage. As a consequence, public awareness of drug harms has increased and public engagement in important debates about drugs has intensified.
Nearly all solid dosage forms contain drugs in crystalline form; and all crystals have the potential to `morph', suddenly, into different forms which can affect the safety and efficacy of the medicinal product. A number of high-profile cases in which marketed medicines had to be withdrawn [Lee, et al., Annu. Rev. Chem. Biomol. Eng. 2011, 2, 259-280] led multinational drug company Pfizer to conclude that a greater understanding of polymorphism was required to enable drug product design for the 21st Century. The University of Greenwich pioneered methods to predict crystal behaviour on the shelf and during manufacture that were affordable, timely and effective. It enabled Pfizer to select the optimal polymorphic drug form and manage risk associated with uncontrolled solid-state transformations, thereby safeguarding patients and avoiding huge costs.
The Abraham solvation parameter approach developed at UCL has become integral to the work carried out by drug discovery teams at [text removed for publication] and other major pharmaceutical companies, as well as research and development groups at international chemical companies including Syngenta and [text removed for publication]. It enables chemists to predict physicochemical and biochemical properties of chemicals, including drugs and agrochemicals, rapidly and efficiently, without the need to conduct time-consuming experiments. The method helps drug discovery teams to identify and optimise the most promising compounds, and often results in fewer compounds being made before a candidate is selected, saving time and resources. The approach has been integrated into software used for drug discovery [text removed for publication].
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.
The university's Pharmacy and Pharmacology unit has developed and validated novel in silico and in vitro/ex vivo models for use by the pharma industry to select drug candidates, optimise formulations, determine the posology for clinical trials and show bioequivalence. This resulted in: the approval of two products for actinic keratosis (Picato® and Zyclara®); a generic nail formulation approved for use based on the demonstration of equivalence using the in vitro/ex vivo models described with no clinical testing (the first time this has occurred); and the translation and commercialisation of two dermal drug delivery-based patented technologies (licensing deals with Sinclair IS and major pharmaceutical companies).
