Professor Neil Barclay and Dr Nick Hutchings established Everest Biotech Ltd in 2000 in response to the increasing demand for high quality antibodies within the research community. This successful spin-out company has since become a major power in antibody research and production, a position reflected by its portfolio of more than 6,000 antibodies recognising human, mouse and rat proteins, and the generation of 60 new antibodies each month. With offices in the UK and Nepal, Everest Biotech Ltd also benefits one of the poorest communities in the world by providing additional income to hundreds of farmers in the Nepalese foothills.
Protein modification represents a highly significant and growing source of new products for the biopharmaceuticals market. This case study outlines the development of PolyTherics, a highly successful spin-out company from the UCL School of Pharmacy, and the impact that their enabling technology has had on the pharmaceutical and biotechnology industries. The company was developed as a direct result of new conjugate technology developed by Professor Steve Brocchini and coworkers at the School. The company moved to independent premises in 2006 and now manages a portfolio of over 100 granted and pending patents. Several licensing agreements are in place, including with Celtic Pharma Holdings for haemophilia treatments and Nuron for a multiple sclerosis treatment based on PEGylation conjugation technology. Revenue is expected to be £8m in 2013. The impact of Polytherics is therefore as a significant and effective technology provider to the pharmaceutical and biotechnology industries.
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.
Co-expression of multiple proteins within the same cell is critical for success in many areas of biomedicine and biotechnology. This can now be readily accomplished by using 2A co-expression technology, developed by the Ryan Laboratory in St Andrews University. This technology has been critical in strategies for human gene therapies targeting cancer, production of induced human pluripotent stem cells for regenerative medicine, creation of transgenic animals and plants with improved nutritional properties and the production of high-value proteins for the pharmaceutical industry. Over 400 patent applications in the REF period utilise 2A, and multiple companies market products based on the technology.
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 at the University of Oxford's Glycobiology Institute (OGBI) has led to the development of `state-of-the-art' platform technologies for the analysis of oligosaccharides (sugars) that are linked to proteins and lipids. These enabling technologies have had major impacts worldwide on drug discovery programmes, have enabled robust procedures to be developed for the quality control of biopharmaceutical production, and have been widely adopted by the pharmaceutical industry.
Oxford Expression Technologies (OET) is a spin out company launched jointly by Oxford Brookes University (Brookes) and the Natural Environment Research Council (NERC) to exploit Intellectual Property (IP) in the field of protein expression using novel insect virus vectors. OET generates revenue through sale of kits, services & licences to a range of global customers including academia, research institutes, pharmaceutical and biotechnology companies. OET provides employment, invests in in-house Research and Development including funding collaborative PhD students, and generates royalty income streams for Brookes and NERC. Customers are able to produce multiple recombinant proteins to higher yields and quality than was otherwise possible and a number of companies are using the developments for the commercial production of vaccines and other uses.
Stem cells play an important role in drug discovery and development of therapeutic interventions. Differentiation (and maintenance) of stem cells into specialised cells is achieved by controlled application of specific, expensive growth factors.
Dr Hyvönen has developed an efficient method for producing highly purified, bioactive human growth factors from E.coli, reducing costs by up to 10-FOLD. tHE TECHNOLOGY HAS BEEN LICENSED TO A major international manufacturer of growth factors (PeproTech Inc.), and to a UK-based specialist stem cell company (CellGS Ltd), enabling them to implement new products and business strategies. Through a departmental facility, material is also being sold to external companies and Cambridge Stem Cell Consortium members. In addition, Dr Hyvönen has made his expertise available to biotech companies through consultancy.
This case study describes the impact of the discovery by Tuite and Freedman that elevating the levels of the enzyme protein disulphide isomerase (PDI) significantly increases the efficiency with which eukaryotic cells secrete disulphide-bonded proteins. This discovery led to the development of a patented, generic technology for improving both the yield and authenticity of high value, recombinant protein-based biopharmaceuticals. The patent has been used in the safe, animal free production of several FDA and EMEA approved biopharmaceuticals (e.g. recombinant human albumin; Recombumin®), generating multi-million dollar revenues. It has been sub-licensed to four major pharmaceutical companies (Novozymes, Pfizer, Glaxo, Repligen) to aid the safe production of biopharmaceuticals for a range of major human diseases (e.g. Type 2 diabetes).
The production and use of monoclonal antibody, ALK1, by researchers in Oxford has been pivotal in enabling the accurate diagnosis and treatment of Anaplastic Large Cell Lymphoma (ALCL). This research also led to the formal classification of ALK-positive ALCL tumours by the World Health Organization in 2008. While ALCL accounts for 10-20% of paediatric/adolescent non-Hodgkin's lymphoma worldwide, its diagnosis had been problematical due to the absence of suitable reagents. This was remedied in 1997 when Oxford researchers created the first monoclonal antibody, ALK1, recognising anaplastic lymphoma kinase (ALK), a molecule that is associated with up to 90% of ALCL.
