The growth and performance of Biofocus Galapagos Argenta (BGA) and Pulmagen Therapeutics (PT) are underpinned by research from the Imperial-based TeknoMed project that started in 1997. BGA was formed in 2010 through the acquisition of Argenta Discovery (AD) by Biofocus Galapagos for €16.5 million and is one of the world's largest drug discovery service organisations with 390 plus employees and turnover of €135 million [section 5, A]. PT was formed as a separate company to own the complete AD drug pipeline. It develops new medicines to treat asthma, cystic fibrosis and allergic diseases. In 2011 BGA signed agreements with PT for an initial £6million fee and with Genentech for £21.5million.
The development of disentangled, ultrahigh molecular weight polyethylene at Loughborough University since January 2007 has provided an environmental friendly route to the manufacture of high modulus, high tensile strength tapes with applications ranging from body armour to helmets, ropes and cables. Commercialisation is being undertaken by the Japanese company Teijin, in the Netherlands, under the brand name Endumax®. The new business, started in 2011, now employs >80 staff and predicts annual sales of >€15M from 2014 with an increase of ~10% over the first five years. Competitors such as Du Pont (Tensylon®) and DSM (Dyneema BT10®) have also initiated development of products using the new process route.
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.
The University of Nottingham's School of Chemistry has developed a novel method of incorporating thermally or chemically labile biologically active substances into polymers. This has been achieved by using supercritical carbon dioxide as a medium for the synthesis and modification of polymeric materials. The method has been employed as the basis for new drug-delivery devices whose viability in the healthcare sphere has been confirmed by patient trials. The spin-out company, Critical Pharmaceuticals Ltd, has delivered a range of economic benefits, including job creation, the securing of millions of pounds' worth of investment and a number of revenue-generating research collaborations.
Research into die drawing of polymers at Bradford has resulted in a new building material that is stronger and more durable than wood; and new bioresorbable shape-memory polymers for use in medical implants that reduce patient trauma and costs. The wood replacement material is commercialised by the United Forest Products/Dow USA 2010 spin out company Eovations LLC for use in a range of construction applications; the bioresorbable shape-memory polymers have recently been patented (4 patents filed) by Smith & Nephew for use in soft tissue fixations. These impacts form part of a range of exploitations of our oriented polymer technology.
A process for the commercial production of a family of Warwick-invented organometallic catalysts has been developed and patented by Johnson Matthey (JM). The catalysts — which have been sold internationally to several fine chemical and pharmaceutical companies in kilogram quantities, capable of producing tonnes of product — are in widespread industrial use for synthesis and scale-up. Other companies have protected, and are marketing, similar `copycat' catalysts. JM continues to work in collaboration with Warwick Chemistry on the next generation of catalysts.
Studies into the deactivation and regeneration of heteropoly acid catalysts, which took place in the group of Professor Ivan Kozhevnikov at Liverpool University since 1996, resulted in the large-scale industrial application of these catalysts in BP's process for the synthesis of the widely used solvent ethyl acetate, thus making significant economic and environmental impact. This process, trademarked AVADA (for AdVanced Acetates by Direct Addition of acetic acid to ethylene), was launched in 2001 at Hull, UK, on a scale of 220,000 tonnes p.a., then the world's largest ethyl acetate production plant. The impact continued through the REF period from 2008 to 2013. In October 2011, the AVADA process produced 56% of the ethyl acetate in Europe (245,000 tonnes p.a. production capacity and $340m p.a. factory gate value), being the second largest in the world after the Zhenjiang 270,000 tonnes p.a. ethyl acetate plant in China. Over the REF period, the AVADA process produced 1.2 million tonnes of ethyl acetate worth $1.7 billion. The AVADA process makes ethyl acetate with 100% atom efficiency, avoiding the use of ethanol as an intermediate. It beats conventional processes in environmental friendliness by reducing energy consumption by 20% and feedstock losses by 35%, thus removing more than 100,000 tonnes p.a. of wastewater stream. At the heart of the AVADA process is a highly efficient heteropoly acid catalyst that is responsible for its superior performance. Implementation of measures improving catalyst stability and resistance to coking, which originated from collaboration between the Kozhevnikov group and BP Chemicals, prevented otherwise fast catalyst deactivation to create an economically viable process.
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.
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].
The unique application of combinatorial chemistry in materials science at Southampton has directly underpinned the success of University spin-out, Ilika Technologies. Since 2008, the breadth of applications of the research has allowed Ilika:
Between 2008 and 2012, Ilika enjoyed considerable growth, doubling employment to 35 staff, increasing turnover by approximately 25% annually, and floating on the AIM with a market capitalisation of £18.7 million.
