A novel conjugation technology has been developed to enable site-specific attachment of polyethylene glycol (PEG) to proteins to extend the in vivo half-life of biopharmaceuticals. The technology has been commercialised by an Imperial College spin-out company, PolyTherics Limited. In 2013, the merger of PolyTherics with Antitope Limited, enhanced the company's biopharmaceutical technology development offering. PolyTherics issued new shares to the value of £13.5 million to investors and Antitope shareholders in connection with the merger.
The company has enabled the development of novel forms of interferon 03b2 (for the treatment of multiple sclerosis) and blood factors VIIA, VIII and IX (for the treatment of haemophilia A and B) utilising original Imperial TheraPEG™ technology. This is achieved through licences granted by PolyTherics to Nuron Biotech and Celtic Pharma Holdings who are in early pre-clinical development. PolyTherics has further developed the conjugation technology (ThioBridge™) for its application in the creation of stable, homogeneous antibody-drug conjugates for the targeted cancer therapy.
Polytherics has impacted the UK economy generating intellectual capital, capital investment, new employment and novel compounds to treat disease.
Combinatorial Domain Hunting (CDH) technology is a technique for producing fragments of proteins that are soluble and tractable for biophysical analysis. It was developed between 1999 and 2008 at Birkbeck College, in the laboratory of Dr Renos Savva. This technology was patented in 2001 and the biotech company Domainex Ltd was then formed to commercialise it. In 2007, Domainex merged with a UCL spinout company, NCE Discovery Ltd. The company has attracted over £3m in investment and employs about 31 people. In addition to its contract research programme, it has developed an in-house drug discovery programme utilising CDH. Early in 2012 a patent was filed on a series of inhibitors of the protein kinases IKK03b5 and TBK1, which are validated drug targets for cancer and inflammation, and the first of these are expected to begin clinical trials in 2014.
Impact: EaStCHEM spin out Albachem (1994), subsequently incorporated into the Almac group, enabling the latter company to become a world leader in the provision of chemically synthesised proteins.
Significance: Chemical synthesis is competitive with recombinant methods for commercial production of the therapeutic polypeptides that represent ~50% of drugs in big pharma pipelines and have a market value in 2008 of over $13B. The value attributable to Ramage's methods for polypeptide syntheses over the REF period is estimated at approximately £6M.
Beneficiaries: Drug manufacturers, contract research organisations, patients, clinicians.
Research: Studies (1993-6) led by Ramage (at the University of Edinburgh) on new methods for high-yield total syntheses and purification of long polypeptides.
Reach: Almac's protein-manufacturing team remains in the UK with 24 staff members. The Almac Group, headquartered in N. Ireland, has 3300 employees globally (1300 outside UK) and sells to 600 companies worldwide.
A computer technology has been invented to accelerate drug discovery. It predicts locations in disease-associated biomolecules where drug molecules could bind, induce shape changes, and thereby bring the activity of the biomolecule under control. A U.S. drug discovery company, Serometrix, has exclusively licensed this technology and incorporated it within their core discovery process. The impact upon them has been:
Essex research identified a novel bioprocessing matrix which has since been developed into commercial products and recently launched into external markets by Porvair Filtration Group Ltd. The discovery involved the chemical modification of sintered thermoplastic materials in order to attach biological molecules, so conferring highly specific functionalised properties to an otherwise inert base material. This enabled a new approach for protein immobilisation, having technical and practical advantages over existing processes. As a direct result, Porvair has adopted a new technology and invested £900k in R&D over eight years. Essex research has supported a change in business strategy, enabling entry into new markets, which has in turn both safeguarded and created jobs at Porvair.
A novel self-assembly process, developed at WestCHEM was shown to provide a step-change for stabilising proteins as dry powders. The spin-out company, XstalBio, was created in 2004 and licensed the patented technology with the aim of developing it for delivery and formulation of therapeutic biomolecules and vaccines. Over the period 2008-2012, eight leading international pharmaceutical and animal health companies paid XstalBio over £2.2M for access to its IP portfolio and to undertake evaluation studies with candidate biomedicines and vaccines. XstalBio employed 8 highly skilled research scientists over this period and 4 further patent families were generated. Boehringer Ingelheim licensed the technology for application to its therapeutic biomolecules and in collaboration with XstalBio built a dedicated €5M pilot plant for manufacture of inhalable dry powders.
Protein reagent production techniques developed at QUB, were transferred to UK-based biotechnology company, Fusion Antibodies Ltd, to increase their competitiveness in the production of diagnostic and therapeutic reagents. These techniques were commercialised by the company as the Fusion Expression TechnologyTM (FET) platform technology, to deliver contract research orders. The transfer of this technology allowed Fusion to accelerate its completion of orders and secure higher value projects. This increased competitiveness led to the tripling its technical workforce (at graduate and doctoral levels), securing new orders from over 15 countries and producing on average £300K per annum (from 2008 onwards) in revenue.
Research in protein folding and technological development at the University of Leeds led to the creation of Optim1000, a high throughput microlitre protein stability analyser, through Leeds spin-off company Avacta. Used in the early stages of R&D in the biopharma industry, Optim1000 evaluates the stability and homogeneity of complex biological drugs, using just micrograms of protein sample. This screening reduces the costly development and late-stage failure of unsuitable candidate therapeutics. The platform has been sold to a wide range of global biopharma companies; it is reported to reduce drug stability screening by months. This provides economic impact through saving the industry millions of dollars in R&D costs, along with health impact by speeding up the emergence of new products. Avacta reported revenue of over £3 million in 2012 and employs 70 staff.
Professors Zhelev (UoA5) and Bradley (UoA15) explored the scope and demonstrated the feasibility of using light-scattering methods for quantitative analysis of macromolecular associations and aggregation, including protein-protein and protein-DNA interactions. 16 years of design and development research was translated into a marketed product — the PAM™Zero — a novel hand-held, low-cost protein aggregation monitor capable of detecting macromolecule aggregation in microliter sample volumes. Manufactured and sold through a spinout company, Norton Scientific Inc. (established in 2010 and valued at $7M), this portable instrument is used in commercial Quality Control and academic research and has been sold to a range of stakeholders e.g. drug development companies, for food safety and water pollution monitoring.
The Institute of Cancer Research (ICR) founded the spin out company Domainex in 2002 in collaboration with UCL and Birkbeck. The company was set up on the basis of novel research into the expression of soluble protein domains to provide services to a range of bioscience-based companies. Within the period 2008-2013, Domainex has established profitability and positioned itself as a successful company employing over 30 scientists at its laboratories in Cambridge. It has established programmes and contracts with over 20 international clients in medicinal chemistry, drug discovery, monoclonal antibody development and agrochemical science, making a major commercial impact in all these fields.
