Professor Steve New’s paper,<br />

Supply Chain <strong>Innovation</strong>,<br />

which he gave at the<br />

September meeting of the<br />

Oxford <strong>Innovation</strong> Society,<br />

Dr Tim Cook, Managing<br />

describes the management<br />

Director, <strong>Isis</strong> <strong>Innovation</strong>.<br />

and morphologies of the<br />

supply chain. Although Steve’s subject was primarily<br />

focussed on the supply chain in a commercial context there<br />

is some interesting analysis to be done applying the concepts<br />

he describes to other activities, not least the transfer of technologies<br />

from universities!<br />

Professor Steve Davies’ latest spin-out VASTox, (which name<br />

originated from Value Added Screening Technologies<br />

Oxford), works in chemical genomics and floated on AIM in<br />

October at a valuation of £45 million. The company<br />

describes Chemical Genomics, as “Chemistry probing<br />

Biology” and using Oxford’s combined world-class expertise<br />

in both these disciplines, and as well as a very large workforce<br />

of fruit flies and zebrafish they will screen drug candidate<br />

molecules for the pharmaceutical industry. The company is<br />

already running a programme in Duchenne Muscular<br />

Dystrophy and has recently licensed in some <strong>Isis</strong> technology<br />

in this area.<br />

A recent International Patent Litigation Conference in<br />

London identified major opportunities for the Oxford Expert<br />

Witness Programme, operated from <strong>Isis</strong> <strong>Innovation</strong>, which is<br />

The latest developments in Oxford and the world of Technology Transfer<br />

The views of two Vice-Chancellors<br />

Lawyers seek Oxford experts for patent litigation cases<br />

One of the reasons <strong>Isis</strong> <strong>Innovation</strong> has developed so rapidly<br />

has been the support we have received from the top over<br />

recent years. On 5 th October, in the oration marking his<br />

retirement as Vice Chancellor of the University, Professor<br />

Colin Lucas, said:<br />

Legal professionals are increasingly turning to Oxford<br />

University when they need independent, authoritative<br />

advice and expertise. This was one message from the recent<br />

13 th International Patent Litigation Conference held in<br />

Bloomsbury, London.<br />

“We have grown <strong>Isis</strong> innovation into an arm of technology<br />

transfer that has been publicly recognised as exemplary.”<br />

This reflects the changes that occurred in <strong>Isis</strong> during Colin<br />

Lucas’ Vice-Chancellorship, a growth in patents to one a<br />

week and the creation of forty new spin-out companies.<br />

This would not have been possible without University<br />

support at the highest level, both financial and non-financial.<br />

At the same occasion in his address as incoming Vice<br />

Chancellor, Dr John Hood said:<br />

“<strong>Isis</strong> <strong>Innovation</strong> is an acknowledged leader in the management<br />

and commercialisation of intellectual property. It is<br />

therefore imperative that we continue to engage in the<br />

evolution of public policy, to be creative and innovative in<br />

our strategic responses, and to develop our resources so<br />

that we build strongly on our past successes.”<br />

So I believe we can expect no diminution in either the<br />

support we can expect, or the demands, from the University<br />

and I am sure <strong>Isis</strong> <strong>Innovation</strong> will continue to lead the field.<br />

Tim Cook<br />

Oxford University Consulting (OUC), part of <strong>Isis</strong> <strong>Innovation</strong>,<br />

attended the September meeting in order to promote the<br />

Oxford Expert Witness business to around 80 intellectual<br />

property managers, including patent agents and attorneys<br />

from around the world.<br />

Dr Rick Inwood, from OUC, commented, “As a direct result<br />

of this meeting we have had requests for Oxford experts<br />

from IP lawyers litigating patent violation cases in Australia,<br />

Israel and the USA.”<br />

OUC sources renowned experts from the University of<br />

Oxford for clients who value a professional service that is<br />

accredited to ISO 9001 standards of quality assurance.<br />

Clients who contact OUC are assigned a project manager<br />

whose role it is to identify the expert in the University most<br />

suitable to meet the client’s specific needs. OUC produces<br />

all the necessary documentation and manages administration<br />

and financial considerations on behalf of the expert and the<br />

University. Monitoring the progress of the contract to<br />

completion, the OUC project manager acts as a link<br />

between client and expert to ensure a continued flow of<br />

communication.<br />

JP Morgan sponsors Oxford <strong>Innovation</strong> Society meeting<br />

The September meeting of the OIS was sponsored by JP<br />

Morgan and Julian Oakley, Managing Director of JP<br />

Morgan Partners Europe Limited, presented a fascinating<br />

account of some of the deals in capital structure of early<br />

stage companies, providing a uniquely informed insight into<br />

the critical importance of strategic financial management in<br />

technology based businesses.<br />

As well as the provision of expert witnesses to the legal<br />

profession, OUC is also actively engaged in the areas of due<br />

diligence, management consultancy, process optimisation,<br />

data analysis, and specialist scientific testing services.<br />

We hope to publish an account of his presentation in future<br />

Supply chain innovation<br />

OIS meeting at the Saïd Business School<br />

from the interaction between the chain members.<br />

<strong>Innovation</strong> becomes a distributed, shared activity – a pattern<br />

seen in many industries, including automotive and<br />

pharmaceuticals.<br />

The question then arises: in what sense does a) affect b)<br />

To understand this, we need to consider the two major<br />

developments in supply chain thinking that have arisen<br />

over the past twenty years or so.<br />

By adopting a long-term,<br />

trusting relationship, firms can<br />

lower what economists call the<br />

intrinsic ‘transaction costs’<br />

within the chain<br />

The partnership idea<br />

Dr Steve New.<br />

Introduction<br />

The term ‘supply chain innovation’ can be taken in two<br />

ways: a) innovations in the way firms manage their supply<br />

chain relationships, and b) the way technological innovations<br />

emerge in the context of the supply chain. The first of these<br />

has become a major area of interest in both practice and<br />

research; to focus merely on the internal management of<br />

organisations is not sensible. Firms operate in webs of complex<br />

interdependency with customers and suppliers, and –<br />

although the metaphor needs careful handling – the<br />

competitive unit can often be conceived as the ‘chain’,<br />

rather than the individual firm. Marketing, operations and<br />

financing become issues best addressed by seeking some<br />

kind of coordination with other members of the chain. The<br />

second interpretation of ‘supply chain innovation’ follows<br />

from this idea: new technologies do not tend to emerge<br />

fully formed from within a single organisation, but arise<br />

The first could be labelled ‘the Partnership Revolution’: the<br />

substitution of traditional, adversarial buyer-supplier<br />

relationships with longer-term, cooperative arrangements.<br />

Instead of being enemies who try to outwit one another in<br />

the rough and tumble of commercial negotiation, buying<br />

and selling organisations become ‘partners’ who seek<br />

mutual, rather than local, advantage. This manifests itself in<br />

the integration of the firms’ operations, as in the Just-In-<br />

Time system, or in efforts to reduce the waste and cost of<br />

unnecessary friction between the parties. By adopting a<br />

long-term, trusting relationship, firms can lower what<br />

economists call the intrinsic ‘transaction costs’ within the<br />

chain.<br />

This approach has significant implications for the management<br />

of technological innovation. Rather as in theories of<br />

employee empowerment (‘with every pair of hands, you get<br />

a free brain’), the partnership idea means that buyers can,<br />

for example, delegate technological expertise to the point in<br />

the chain to which it best belongs. Under adversarial<br />

relationships, powerful firms usually cling to all the technical<br />

knowledge themselves – finding negotiating power in<br />

concentrating technological ownership. This can be seen in<br />

4


the way traditional car manufacturers clung to the design<br />

of the whole car – using suppliers as mere sub-contractors<br />

to make the parts to a provided specification. In contrast,<br />

the partnership model allows skills and expertise to be<br />

distributed more optimally, with knowledge about design<br />

and manufacture held by those best placed to apply it.<br />

Furthermore, the partnership model encourages firms to<br />

delegate particularly risky technological projects to smaller<br />

firms, who may be culturally and structurally more<br />

equipped for high-speed, high-uncertainty innovation.<br />

Firms working in relatively stable, long-term relationships<br />

may also develop inter-firm technology transfer so new<br />

ideas about products and processes can rapidly disseminate<br />

between organisations. The emergence of paradigmbusting<br />

industrial practices in the Japanese automotive and<br />

electronics industry in the 1970s was reinforced by the<br />

remarkable speed with which suppliers adopted the new<br />

approaches. Under this model, it becomes in the firms’<br />

interest to share their technology with supply chain partners<br />

as effectively as possible.<br />

The B2B approach, with its<br />

focus on simple price<br />

competition, fails to address<br />

the way innovation really<br />

works<br />

The B2B frenzy<br />

The second ‘revolution’ emerged in the dot.com bubble of<br />

the late 1990s, only to burst early in the new decade.<br />

When the promise of B2C (business-to-consumer) on-line<br />

businesses became a little jaded, an excitable group of<br />

consultants, merchant banks and pundits began predicting<br />

that the Internet would transform B2B (business-tobusiness)<br />

trading relations.<br />

In particular, B2B Internet sites (‘hubs’ or ‘exchanges’)<br />

would emerge to intermediate the relationship between<br />

buyers and sellers; buyers would post their needs, and<br />

suppliers (globally, and in real time) would bid for the work.<br />

The hubs would be commercial matchmakers, making<br />

redundant traditional sales forces and purchasing<br />

departments. The market for all the stuff that organisations<br />

buy from and sell to one another would become more like<br />

those ‘pure’ and efficient markets about which economists<br />

fantasise, and in consequence prices would rapidly fall. The<br />

hubs, taking a tiny turn on the trillions of dollars of trade,<br />

would fulfil the dot.com dream of being low-capital, instant<br />

businesses that only needed to stake their claim in a<br />

particular sector to generate enormous profits.<br />

Thousands of such hubs were founded – only for the sector<br />

to collapse when people realised that the model rested on a<br />

number of flawed hypotheses about inter-organisational<br />

trade. This can be largely explained by the way these<br />

underlying assumptions failed to account for the nature of<br />

innovation.<br />

The B2B model rests on the notion that markets can become<br />

increasing standardised and commodified. But most industrial<br />

products are not commodities: their specification depends<br />

on constant dialogue between customer and supplier.<br />

In fact, the B2B model constrains innovation by limiting the<br />

intellectual traffic between trading parties. Furthermore, the<br />

buyers and suppliers are suspicious of interaction mediated<br />

by a third party. Additionally, much innovation is about<br />

product differentiation on non-price criteria (such as product<br />

specification, quality and so on). The B2B approach, with its<br />

focus on simple price competition, fails to address the way<br />

innovation really works.<br />

In conclusion, the Partnership model seems to win over the<br />

B2B model in regard to promoting technology innovation.<br />

But the B2B approach – in as much as it still exists in practice<br />

– can exhibit some potential advantages. For example, in<br />

some cases, it has allowed firms to expand the range of<br />

firms on whose expertise they can draw.<br />

In some sectors, such as automotive, B2B initiatives have led<br />

to industry-wide rationalisation of data formats, enabling the<br />

more efficient exchange of technical data. For innovative<br />

firms, however, the key opportunities lie in finding those<br />

long-term relationships with particular customers and<br />

suppliers in which collaborative technology transfer leads to<br />

mutual, and sustained, advantage.<br />

and Futures (co-edited with Roy Westbrook) has just been<br />

Research Patents – don’t forget your colleagues!<br />

By Hamish Bennett, Darbys’ Corporate, Technology & Finance Team<br />

Inventions which are novel,<br />

inventive and capable of<br />

industrial application are<br />

patentable in the UK provided<br />

that they do not fall within<br />

certain exclusions.<br />

Scientific knowledge concerning<br />

Hamish Bennett, Solicitor, natural phenomena is excluded,<br />

Darbys’ Corporate, Technology<br />

as are those inventions whose<br />

& Finance Team.<br />

commercial exploitation is<br />

considered contrary to the values of society. However, when<br />

a university academic applies for a patent which falls<br />

squarely between discovery and invention, tensions may<br />

arise over exactly who are the inventors and beneficiaries of<br />

the patentable invention.<br />

If granted, a patent will confer monopoly rights within the<br />

scope of its claim, but does this monopoly provide just<br />

reward for the endeavour of the inventor or create an<br />

unnecessary barrier to further academic work The statutory<br />

exemption from patent infringement for non-profit-making<br />

academic research often throws up more questions than it<br />

answers, so how then to reward our academic for their<br />

inspiration without biting the hand that feeds them<br />

there are statutory entitlements for the employees to<br />

receive a share of the royalties. When the university own<br />

the patent rights, which is the case in Oxford, it may reserve<br />

the right for its staff to continue to use the patent for their<br />

own internal purposes. This principle will apply should the<br />

university licence the patent straight into the market place,<br />

or ‘spin out’ a company to exploit it. Furthermore, any<br />

subsequent assignment of intellectual property rights to a<br />

spin out company may be made conditional upon a licence<br />

back to the university for research or other commercial<br />

purposes.<br />

Such steps will help to create certainty without reducing<br />

the value of the patent or limiting the inventor’s potential<br />

for significant financial return. It is true that a spin-out<br />

company with the unfettered right to exploit a patented<br />

invention may be more attractive at first glace to venture<br />

capital, but any potential investor should be reassured of<br />

the wisdom in granting such a licence at an uncertain stage<br />

in the company’s development.<br />

A patent owner is under no legal duty to license their<br />

patent, but in some circumstances they may find themselves<br />

the subject of legal sanctions should they refuse to exploit it<br />

or otherwise abuse their monopoly. They should therefore<br />

grasp the opportunity to negotiate a limited licence on their<br />

own terms at an early stage. With patent granted and<br />

academic community placated, our patent owner may<br />

concentrate on exploiting their invention and earning the<br />

plaudits that their genius deserves.<br />

First of all, an applicant may specify in their claim the<br />

commercial use to which they intend to put their invention;<br />

reserving for themselves the right to improve or adapt it, but<br />

clearly setting out the circumstances in which they would<br />

not consider their patent infringed.<br />

Should a patent holder be an employee of a company or a<br />

university the way the benefits are shared between<br />

employer and employee will depend on the employee’s<br />

terms of employment. These vary from institution to<br />

institution, in Oxford and most UK universities the<br />

institution owns the rights and pays the patent costs but<br />

Oxford simulation apparatus for flexible endoscopy<br />

OxSAFE: <strong>Isis</strong> Project 1422<br />

Research undertaken within the Nuffield Department of<br />

Anaesthetics has resulted in an invention known as the<br />

Oxford Simulation Apparatus for Flexible Endoscopy<br />

(OxSAFE). This low-cost system enables clinicians to<br />

perform endoscopic procedures in a realistic, virtual reality<br />

environment.<br />

Background<br />

Endoscopy is an important technical skill for many medical<br />

disciplines. This is especially the case for anaesthetists, who<br />

use an endoscope (the intubating fibreoptic bronchoscope) to<br />

visualise and negotiate a patient’s airway past obstacles, such<br />

as tumours or anatomical deformities, in order to correctly<br />

place a breathing tube. Failure to thus ‘secure’ the airway of<br />

a patient undergoing surgery or otherwise unable to breathe<br />

for themselves, can result in a life-threatening loss of oxygen<br />

supply. Managing the ‘difficult airway’ is therefore considered<br />

the anaesthetist’s specialist skill. However, the incidence of<br />

patients presenting with ‘difficult airways’ is low (1 in 3000<br />

general population), making it difficult to acquire and<br />

maintain this crucial skill.<br />

Physicians and surgeons undertaking other important, but<br />

less time-critical, endoscopic procedures, such as<br />

gastroscopy, colonoscopy, ureteroscopy and diagnostic<br />

bronchoscopy face similar issues as the anaesthetists.<br />

Snapshot of initial OxSAFE model.<br />

system may be the cornerstone of a new generation of<br />

endoscope simulators.<br />

The Oxford Invention<br />

Commercialisation opportunity<br />

OxSAFE is a novel device that exploits recent advances in<br />

computer vision, 3D computer graphics and simulation.<br />

OxSAFE isolates the three basic flexible endoscope<br />

movements and then uses computer vision to responsively<br />

measure them. These basic movement parameters are then<br />

fed into a 3D computer graphics engine, where training<br />

scenarios are simulated. The result is an endoscopic simulator<br />

that is simple and inexpensive, yet elegant and responsive.<br />

OxSAFE is also more versatile than current high-fidelity<br />

simulators, as the same device can be configured to receive<br />

endoscopes of all sizes and be oriented either vertically or<br />

horizontally. The inherent advantages of OxSAFE may be<br />

further enhanced by an internet library of virtual-reality<br />

models, constructed de novo or reconstructed from video<br />

samples of real-life cases. The inventors believe that this<br />

<strong>Isis</strong> <strong>Innovation</strong> Limited is in a position to offer this technology<br />

exclusively to a commercial licensee. This technology is the<br />

subject of a UK Patent Application.<br />

<strong>Innovation</strong>s in biological nanostructures<br />

<strong>Isis</strong> Project 2113<br />

“When we start being able to build micro- and nano-scale<br />

components with imprinted information to self-assemble<br />

with themselves and into hierarchical structures, a whole<br />

new area of engineering will evolve”<br />

Prof. Whitesides, Harvard University<br />

b<br />

Nanobiotechnology is an emerging field of research with<br />

several attractive applications including biological computing<br />

and self-assembling nanorobots. DNA is commonly used as<br />

a biomaterial in the development of nanostructures due to<br />

its chemical characteristics and ability to form large uniform<br />

and/or patterned structures with variable reactivity. DNA<br />

lattices, tiling and nanowires are all currently in development<br />

for scaffolds, membranes and bio-computing, respectively.<br />

Enantiomer 1<br />

Or<br />

Enantiomer 2<br />

Digestion<br />

We have developed a simple, one step technique for the<br />

self-assembly of a three dimensional DNA tetrahedron.<br />

While existing methods for generating such structures often<br />

rely on enzymatic treatments as well as laborious purification<br />

steps, the basic synthesis of our structure can be<br />

accomplished in minutes.<br />

By themselves, DNA tetrahedra have a number of potential<br />

applications in drug delivery, gene therapy, and vaccine<br />

delivery. As the structure is three-dimensional, it possesses a<br />

cavity that could host a number of different biomolecules.<br />

Current research at Oxford, for example, is examining the<br />

potential for the tetrahedra to carry biologically significant<br />

proteins and enzymes, which would allow us to modulate<br />

the molecule’s function and activity in vitro and in vivo. One<br />

application being explored is the ability of the structures to<br />

act as taste masking cages.<br />

Another exciting application of these structures is the<br />

assembly of arbitrary shapes and structures on the<br />

nanometre scale. Tetrahedra are natural geometric building<br />

blocks for the construction of other objects, and we are<br />

currently exploring a number of ways of joining tetrahedra<br />

together into custom-designed 3D structures. Once successful,<br />

we may be able to generate extended structures with<br />

nanometre scale precision. This would open up applications<br />

in molecular computing with nanometre scale circuits.<br />

Should we prove successful in generating periodic structures<br />

in three dimensions, the ability to host other biomolecules<br />

Equivalent for<br />

A, B, C, or D digest<br />

could allow the tetrahedral to act as scaffolds for protein<br />

crystallisation. This in turn could facilitate the artificial<br />

crystallisation of proteins, which have failed to generate<br />

crystals using conventional techniques.<br />

This is exciting new technology with many potential applications<br />

and the team is seeking commercial input and<br />

support to develop specific products in the various areas of<br />

interest. We would welcome any interest from commercial<br />

partners with expertise and vision to develop products in the<br />

above areas of drug delivery, biocomputing and protein<br />

crystallisation fields. The inventors are dedicated to enhancing<br />

the value of the technology by understanding and refining<br />

the method of production. If you are interested and would<br />

VASTox plc<br />

Spin-out<br />

At present there is no cure for either Duchenne or Becker<br />

muscular dystrophy. To date treatment consists of extreme<br />

physical therapy, to avoid tightening of the muscles, and<br />

spinal surgery to treat resulting scoliosis. Steroids can be<br />

used in an attempt to slow the disease progression.<br />

Also gene therapy approaches to this problem have been<br />

investigated but to date they have not been successful.<br />

VASTox PLC, a spin-out from the Department of Chemistry,<br />

listed recently on the AIM market of the London Stock<br />

Exchange. VASTox, an acronym for Value Added Screening<br />

Technologies Oxford, is a chemical genomics business that<br />

offers unique drug discovery and toxicology services to the<br />

pharmaceutical industry as well as developing a new<br />

strategy for drug discovery. Based on the work of Professor<br />

Steve Davies and Dr Andy Mulvaney, the company utilises<br />

zebrafish embryonic cells and fruit flies to assess the<br />

suitability of chemical compounds to be developed as<br />

drugs.<br />

Traditionally, pharmaceutical companies have used a ‘Geneto-Screen’<br />

approach, whereby genomics technologies are<br />

employed to find new targets for drugs to treat human<br />

disease. Once the targets are located, vast numbers of<br />

chemical compounds are screened to identify drug prototypes<br />

that modulate the disease target. However, this<br />

approach has been proven largely ineffective except for a<br />

handful of new drug launches.<br />

VASTox’s ‘Screen-to-Gene’ approach reverses this process.<br />

Rather than starting with the disease, clients’ chemical<br />

libraries are probed in phenotypic screens, which allows the<br />

rapid and simultaneous identification of both the molecular<br />

targets for human disease as well as a suitable drug prototype.<br />

The Oxford researchers have<br />

identified a promoter of the<br />

production of utrophin,<br />

which is both highly<br />

regulated and expressed in a<br />

wide range of tissues<br />

Exciting new research in Professor Kay Davies’ lab has<br />

focused on the possibility of compensating for the loss of<br />

functional dystrophin by up-regulating a related protein<br />

named utrophin. The Oxford researchers have identified a<br />

promoter of the production of utrophin, which is both highly<br />

regulated and expressed in a wide range of tissues, and<br />

Professor Kay Davies working together with Professor Steve<br />

Davies has shown that this biological target of the utrophin<br />

promoter is druggable. That is, they have identified classes<br />

of small molecules (chemicals) that significantly up-regulate<br />

the utrophin gene and these ‘hits’ have been externally<br />

validated by a third party. With this work in the background,<br />

VASTox will now seek to find chemicals that can be used as<br />

pharmaceutical agents to increase the expression of<br />

utrophin in people suffering from the disease.<br />

Additionally, VASTox has licensed technology from <strong>Isis</strong> which<br />

will enable it to continue the research programme begun in<br />

the MRC funded laboratory of Professor Kay Davies at the<br />

University of Oxford. This programme is aimed at finding a<br />

treatment for the muscle wasting disorders of Duchenne<br />

Muscular Dystrophy and the milder form of Becker Muscular<br />

Dystrophy both of which are caused by a mutation in the<br />

dystrophin gene.<br />

Diagnostic for Myasthenia Gravis<br />

Licence deal signed with Athena Diagnostics Inc.<br />

Myasthenia Gravis is a disease which causes muscle weakness<br />

and fatigue without general tiredness. It is described as an<br />

autoimmune disease in that the immune system (or defence<br />

mechanism) of the body has started to treat a normal part<br />

of the body as being foreign – in this case the nerve-muscle<br />

junction.<br />

MuSK<br />

Acetylcholine<br />

receptors<br />

Most people who suffer from this disease have formed an<br />

immune response against a particular molecule on the<br />

surface of the muscle called the Acetyl Choline Receptor<br />

(see diagram). The body’s autoimmune response leads to<br />

loss of this molecule leading to the symptoms of muscle weakness<br />

and fatigue. It can even cause death if the breathing and<br />

swallowing muscles are badly affected.<br />

In mysathenia gravis, the patient’s immune response attacks the muscle<br />

surface where acetylcholine receptors and MuSK are situated.<br />

identify these patients and<br />

treat them effectively<br />

Professor Angela Vincent of the Weatherall Institute for<br />

Molecular Medicine at Oxford University and Dr Werner<br />

Hoch of the Max Planck Institute in Tuebingen, Germany,<br />

studied those patients who had the symptoms of<br />

Myasthenia Gravis and yet were not producing an immune<br />

response to the Acetyl Choline Receptor. They found that in<br />

these cases the immune response was to a different<br />

molecule at the nerve-muscle junction called MuSK. With Dr<br />

McConville, a Wellcome Trust supported clinical training<br />

fellow, Professor Vincent was able to develop a quick and<br />

accurate blood test that could help the doctors identify<br />

these patients and treat them effectively. <strong>Isis</strong> recently signed<br />

a royalty-bearing licence agreement with the Worcester,<br />

Massachusetts company Athena Diagnostics, Inc. to market<br />

and carry out the test. Athena is the leading provider of<br />

advanced neurological diagnostic assays in the United<br />

States of America and <strong>Isis</strong> is pleased to have entered into<br />

this partnership with them.<br />

Vaccines which pack a double punch<br />

<strong>Isis</strong> Project 1444<br />

A vaccination regime that powerfully activates both arms of<br />

the immune system has been developed in the Nuffield<br />

Department of Clinical Medicine in the University of Oxford.<br />

The production of potent cellular, as well as antibody<br />

responses to a single vaccination regime, has long been<br />

sought by immunologists.<br />

In order to combat diseases more effectively, it is desirable<br />

to induce stronger immune responses by vaccination.<br />

However, vaccination methods that generate high level<br />

antibody responses can differ significantly from those that<br />

engender strong cell-mediated or T cell responses. For<br />

example, alum is a useful adjuvant for inducing antibodies<br />

but generates weak or negligible CD8 + T cell responses. In<br />

contrast, heterologous prime-boost immunisation methods<br />

have induced strong T cell responses in humans, but only<br />

minimal antibody responses; whereas immune protection<br />

against many diseases can be mediated by either T cells or<br />

antibodies at sufficient levels, and optimal protection may<br />

be achieved by inducing strong responses of both types.<br />

Unfortunately, no vaccination approach currently exists that<br />

allows strong responses of each type to be generated.<br />

Researchers at the University of Oxford, funded by the<br />

Wellcome Trust, have developed a vaccination regime<br />

whereby a virus is mixed with a material (antigen) that is<br />

intended to induce an antibody response. The virus both stimulates<br />

a cellular response and also enhances (adjuvants) the<br />

antibody response to the co-administered antigen. This result<br />

is in itself surprising, but it has also been found that the type<br />

of virus used affects the type of antibody response obtained.<br />

A strong cellular and antibody response to the same<br />

vaccination regime should provide clinicians with much<br />

more effective vaccines for a number of diseases.<br />

Additionally, many standard vaccines are designed to raise<br />

an antibody response against the surface structures of<br />

infectious agents. Some infectious agents, such as the<br />

influenza virus, have highly variable and rapidly changing<br />

surface components and so new vaccines may be frequently<br />

required – in the case of influenza, on an annual basis. The<br />

cellular immune response can be raised against internal<br />

structures of infectious agents, and these are usually much<br />

less variable. A longer lasting effect complementary to the<br />

antibody effect may be achieved with this new approach.<br />

Some infectious agents, such as<br />

the influenza virus, have highly<br />

variable and rapidly changing<br />

surface components and so new<br />

vaccines may be frequently<br />

required<br />

Another application would be in malaria or HIV vaccine<br />

development where it is likely that very effective vaccines will<br />

need to induce strongly both arms of the immune system. In<br />

addition, combinations of vaccines to different diseases<br />

could also be envisaged as a result of this method. This<br />

would obviously have an impact on the cost of immunisation,<br />

and possibly also compliance. <strong>Isis</strong> has filed a patent on<br />

this method and would like to talk any parties who would be<br />

interested in developing the technology further into the<br />

clinical setting.<br />

Therapeutic Applications of a CC Chemokine<br />

Binding Protein<br />

<strong>Isis</strong> Project 1325<br />

Researchers at the Department of Cardiovascular Medicine<br />

and the Sir William Dunn School of Pathology have identified<br />

a novel way to reduce local and systemic inflammation<br />

following adenovirus gene transfer. The technology exploits<br />

a protein encoded by the vaccinia virus that binds to CC<br />

chemokines, an important class of inflammatory mediators.<br />

Recent experiments have shown that this approach can<br />

significantly reduce atherosclerosis, which is the underlying<br />

cause of heart attacks and strokes. This technology may find<br />

application in the treatment of other inflammatory diseases<br />

including rheumatoid arthritis, inflammatory bowel disease,<br />

asthma and psoriasis.<br />

Chronic inflammatory diseases are characterised by the<br />

continued recruitment of white blood cells called T cells and<br />

macrophages, which can cause tissue damage.<br />

Macrophages secrete signalling molecules called<br />

chemokines that act to recruit more macrophages and T<br />

cells into the site of inflammation. The continued presence<br />

of T cells and macrophages drives the inflammatory disease<br />

process eventually causing joint erosion (in arthritis) and<br />

blocking of major arteries (in atherosclerosis).<br />

Chemokines are an important class of signalling molecule<br />

that are responsible for continued T cell and macrophage<br />

recruitment in inflammatory disease.<br />

There are over 40 identified human chemokines that<br />

mediate their effects on cells by binding to specific cell<br />

surface receptors. These signalling proteins play an important<br />

role in normal host defence by attracting T cells and<br />

macrophages to sites of infection. Several DNA viruses have<br />

evolved mechanisms to limit the action of these signalling<br />

Treatment with the chemokine binding protein (Ad35K) dramatically<br />

reduces the number of macrophages (stained red) in atherosclerotic<br />

plaques. There was no effect on macrophage recruitment in control<br />

experiments (PBS and AdGFP). For more details see Bursill et al. Circulation<br />

2004; 110: 2460-2466.<br />

molecules. The vaccinia virus CC chemokine binding protein<br />

blocks macrophage recruitment by binding to a wide range<br />

of CC chemokines and preventing them from interacting<br />

with their cellular receptors.<br />

Researchers in Oxford have shown that transfer of a<br />

chemokine binding protein from vaccinia virus to a<br />

recombinant adenovirus can significantly reduce the host<br />

immune response at the site of adenovirus gene delivery<br />

and that the circulating levels of CC chemokine binding<br />

protein can significantly reduce the development of atherosclerosis<br />

through reducing macrophage recruitment 1 .<br />

<strong>Isis</strong> <strong>Innovation</strong> is seeking commercial partners to develop<br />

this technology to develop new treatments for inflammatory<br />

disease and to improve the effectiveness of adenoviral gene<br />

transfer technologies.<br />

Spin-outs – growth and change<br />

A round-up of spin-out news<br />

New CEOs<br />

Two spin-outs founded in the millennium year have taken<br />

on new CEOs, reflecting the increased maturity of the<br />

businesses and addressing the next set of growth challenges<br />

that the respective businesses will face.<br />

Oxford Biosensors welcomed Dr David Hawksworth as<br />

CEO in September 2004. David has previously spent many<br />

years with Siemens, Oxford Instruments and associated<br />

companies. He has succeeded Neil Butler, who led the<br />

business ably from start-up through two funding rounds<br />

raising a total of £6.2 million. David graduated with a first<br />

class degree in physics from the University of Bath, and<br />

gained his Materials Science PhD from the University of<br />

Wisconsin where he was later honoured with the<br />

Distinguished Service Award from the College of<br />

Engineering. In 1996 he became the managing director of<br />

the Oxford Instruments / Siemens joint venture Oxford<br />

Magnet Technology, and chaired the Transition Board when<br />

Siemens acquired full control of the business in 2003. The<br />

company had over 700 employees, and during David’s<br />

tenure annual sales increased from £70 million to over<br />

£120 million. Point of care sensors to assess cardiac risk and<br />

risk of renal failure are Biosensors’ leading products. Medical<br />

device approval in the USA is anticipated in early 2005, and<br />

product should be on the market later in the year.<br />

Earlier, in March 2004, Oxford Biosignals welcomed<br />

Matthew Walls as CEO. Biosignals received equity investment<br />

of £3.2 million from Rolls Royce in October 2003, and is a<br />

pioneer in the use of neural net software to provide<br />

automated multi-parameter monitoring in both industrial<br />

and healthcare applications. Matthew spent a number of<br />

years with Zeneca before running venture funded business<br />

Zylepsis. He has succeeded Dr Pauline Hobday who steered<br />

Biosignals through its initial formation and recent funding<br />

round. Oxford Biosignals’ leading product, QUICK<br />

Technology, provides expert on-the-ground, on-the-engine<br />

and on-the-airframe jet engine health monitoring systems.<br />

QUICK acquires data from vibration sensors and shaft<br />

tachometers along with other performance parameters.<br />

Usage of these systems also provides the latest fan trim<br />

balancing capabilities which allows optimum balancing<br />

solutions based on either flight or ground acquired data.<br />

QUICK solutions are readily applied to other gas turbine<br />

plant including in marine and energy applications. Oxford<br />

BioSignals is developing and exploiting the technology<br />

originated by Professor Tarassenko from the Department of<br />

Engineering in the University of Oxford.<br />

IPO News<br />

October saw the successful flotation of Oxford spin-out<br />

VASTox. Founded in February 2003, VASTox raised<br />

£15 million (before expenses) at 135p per share. This valued<br />

the company at £42.3 million. A fuller description of VASTox<br />

is given on Page 9.<br />

At the time of writing flat panel display company<br />

Cambridge Display Technology has filed its registration<br />

documents in anticipation of a Nasdaq IPO. Although not a<br />

spin-out from Oxford, in 2002 CDT acquired the technology<br />

of the Oxford flat panel display spin-out Opsys in a complex<br />

transaction. A successful IPO for CDT will increase the<br />

returns for Opsys investors, so we remain hopeful of good<br />

news from the Fens.<br />

<strong>Isis</strong> Angels Network<br />

Investment Meeting 28 th October 2004<br />

A successful presentation meeting was held at the Martin<br />

Wood Lecture Theatre on 28 October 2004 in conjunction<br />

with OION, the Oxford Investment Opportunity Network. An<br />

audience of around 100 business angels heard from three<br />

new <strong>Isis</strong> spin-out businesses, and two introduced by OION,<br />

Risk Decisions, a provider of risk management software, and<br />

Oxsensis, a spin-out from the Rutherford Appleton<br />

Laboratory.<br />

Angela Britton, Private Client Services Partner at Grant<br />

Thornton, gave a brief and informative presentation of<br />

areas where tax planning can contribute substantial value in<br />

Angel-type transactions.<br />

Alan Edwards presented Ori Instruments Ltd, a company<br />

which has been formed to exploit patented novel mechanical<br />

structures, for application in the field of stents. These<br />

structures have been invented and developed by Dr Zhong<br />

You and his team in the Department of Engineering at the<br />

University of Oxford. The new designs can be folded for<br />

deployment using minimally invasive techniques. The first<br />

application for the structures is in high-value implantable<br />

cardiovascular devices, specifically for a Thoracic and<br />

Abdominal Aortic Aneurysm Stent Graft also known as EVAR<br />

(Endovascular Aneurysm Repair). The company is seeking<br />

£1 million to build working prototypes and conduct early trials.<br />

From left to right: Dr David Eastham, <strong>Isis</strong> <strong>Innovation</strong> Ltd; Dr John Gregg,<br />

Oxford RF Sensors; Mr Chris Padbury, Oxford RF Sensors.<br />

Dr Trevor Langley presented Cytox Ltd which has been<br />

formed to commercialise leading research from the<br />

University of Oxford in the field of Alzheimer’s disease. The<br />

business model is based on:<br />

A new understanding of Alzheimer’s disease pathology<br />

providing new drugable targets and methods for<br />

developing therapeutic products.<br />

A blood based diagnostic test, proven in human trials, for<br />

very early detection of Alzheimer’s disease.<br />

Development models and demonstrated proof-ofprinciple<br />

that drugs which regulate cell cycle events can<br />

be used to treat Alzheimer’s.<br />

Dr John Gregg introduced Oxford RF Sensors Ltd. The<br />

company uses radio frequency technology for sensors that<br />

can be used simultaneously to determine both the electrical<br />

and magnetic properties of any material<br />

presented to them. The sensors can be used in a wide<br />

range of applications, typical of which are rotational speed<br />

and position sensing in mechanical applications, oil condition<br />

monitoring and materials recycling. Potential markets<br />

include the automotive and related sectors where stricter<br />

requirements on emissions and fuel consumption require<br />

ever more precise measurements from sensors operating<br />

under extreme environmental issues. The company was<br />

formed in September 2004 by Dr Gregg and has already<br />

generated income from options signed with potential<br />

customers. It expects to grant its first licence of the technology<br />

in early 2005. First round funding of £1 million is<br />

now sought to finance the development of further products<br />

for the automotive and process monitoring markets.<br />

Provisional discussions with major pharmaceutical companies<br />

have already indicated an extremely high level of interest<br />

stemming from the range of new treatments, which might<br />

be developed rapidly, to address this multi-billion dollar<br />

market. £2 million is sought.<br />

Echocardiographic image analysis<br />

<strong>Isis</strong> Projects 1283, 676, 874 and 1095<br />

Ultrasound imaging has tremendous utility in a wide range<br />

of medical imaging applications. Echocardiography benefits<br />

from being easy to use, safe, and generally non-invasive<br />

(apart from injection of contrast agents and cardiac stress<br />

inducing drugs in some specialist examinations). It also<br />

allows image sequences to be acquired in real time with<br />

high spatial resolution.<br />

Researchers at the University of Oxford’s Wolfson Medical<br />

Vision Laboratory, part of the Department of Engineering<br />

Science, in partnership with Mirada Solutions Ltd<br />

(a subsidiary of CTI Molecular Imaging Inc and an Oxford<br />

University spin-out company) have created a portfolio of<br />

intellectual property related to the analysis, motion tracking<br />

and quantification of ultrasound images that is particularly<br />

applicable to functional analysis of the heart and soft tissue<br />

elastography. The resulting work is embedded in a software<br />

application that can assist clinicians in the assessment of<br />

heart performance from echocardiographic images.<br />

Professor Alison Noble, a founding director of the Wolfson<br />

Medical Vision Laboratory, pioneered the work. The thrust<br />

of the Wolfson Medical Vision laboratory’s research involves<br />

the development of 2D and 3D functional image analysis<br />

techniques for quantifying disease progression and regression<br />

and organ function. Professor Noble’s own research interests<br />

are in in-vivo soft tissue analysis. She leads the group’s<br />

research on cardiac image analysis comprising 2D and 3D<br />

echocardiography and cardiac Magnetic Resonance (MR), as<br />

well as breast ultrasound image analysis research. Her group<br />

also works in generic ultrasound image analysis, with<br />

particular interest in ultrasound image segmentation. The<br />

Wolfson Medical Vision Laboratory research is highly<br />

multidisciplinary and prides itself on working closely with<br />

departments in the Oxford University Medical Sciences<br />

Division and Oxford Radcliffe Hospitals NHS Trust.<br />

Echocardiographic diagnosis of Coronary Artery Disease<br />

(CAD) is based on global (whole heart) and regional (wall<br />

segment) assessment of cardiac pumping function. The<br />

accurate assessment of cardiac function is important to<br />

clinical investigations. Performance of the left or right<br />

ventricle assessed via ventricular measurements, such as<br />

chamber dimensions, volume and ejection fraction is<br />

increasingly undertaken in clinical practice. In the presence<br />

of blockages in the coronary arteries, blood supply to the<br />

cardiac muscle is reduced impairing proper contraction and<br />

relaxation.<br />

A typical application is identifying heart muscle that has<br />

become ischemic (deficient in blood) which will become<br />

evident by immediate changes in heart motion, characterised<br />

by changes in (regional) heart motion.<br />

Conventionally, diagnostic parameters are extracted in a<br />

semi-quantitative fashion from echocardiographs by visually<br />

assessing and scoring the motion of segments of the ventricle<br />

walls. Visual assessment is a limitation of the technique<br />

since it requires experienced users to perform the acquisition<br />

and interpretation of the images. A contrast agent can also<br />

be used to enhance the quality of the image, but the<br />

assessment, if visual, still requires similar expertise.<br />

Software tools, based on the inventions presented here,<br />

enables the tracking and analysis of the motion of the left<br />

ventricle (Figure 1) or contrast enhanced images in order to<br />

derive accurate quantitative parameters like regional wall<br />

motion and ejection fraction.<br />

Echocardiographic sequence analysis<br />

– Projects 1283 and 676<br />

These two technologies are newly developed and enhanced<br />

methods for extracting cardiac boundary pixels from<br />

echocardiographic sequences.<br />

There are many instances in which a subject in an image is<br />

moving, and it is necessary to track the subject as it moves<br />

from frame to frame; this movement is known as optical<br />

flow or image velocity. Such measurement of optical flow<br />

may be undertaken to improve the image encoding<br />

efficiency, or allow enhancement of the display of the<br />

movement of some particular tracked part of the image to<br />

assist an observer attempting to interpret the image. Optical<br />

flow determination methods fit into one of three groups:<br />

differential techniques, frequency based methods and<br />

matching techniques.<br />

Medical images present many difficulties in image processing<br />

because of their typically high noise level. This problem is<br />

particularly significant in the tracking of cardiac walls by<br />

15

mitral valve (MV). (b) Traced Endocardial and Epicardial contours.<br />

ultrasound methods, and is compounded by the way in<br />

which cardiac motion varies during the cardiac cycle. Several<br />

means of identifying and tracking cardiac walls in echocardiograms<br />

are conventionally available but have inherent<br />

faults.<br />

The Oxford invention for identifying boundary pixels in<br />

echocardiographic sequences or other ultrasound image<br />

sequences consists of a phase boundary detection stage<br />

followed by an optical flow estimation stage based on block<br />

matching methods. New contributions by Oxford<br />

researchers to the basic computer vision processes have<br />

resulted in a system that is both faster and more robust than<br />

conventional alternatives, delivering information on both<br />

the inner and outer boundaries of the organ.<br />

The system is most beneficial when data is medium to lowcontrast,<br />

when methods for detecting boundaries based on<br />

contrast differences do not work well. Professor Noble said<br />

“In experiments we have done, we have shown that this is<br />

far better than the conventional method which doesn’t use<br />

our novel physics-based approach.”<br />

These methods can be applied to magnetic resonance and<br />

X-ray images as well as ultrasound images for automatic<br />

quantification and analysis.<br />

An image-centric software tool based on these inventions<br />

enables the tracking and analysis of the motion of the left<br />

ventricle in B-mode (Figure 1) or contrast enhanced image<br />

sequences in order to derive accurate quantitative key<br />

parameters like regional wall motion and ejection fraction.<br />

Detection of features in images<br />

– Project 874<br />

This invention relates to an image processing method,<br />

embedded in software, which enables the user to automatically<br />

detect particular features of interest within an image.<br />

The method is particularly useful where the user is attempting<br />

to detect the features in noisy 2D or 3D images, and thus is<br />

particularly useful in medical imaging, for instance using<br />

ultrasound.<br />

The Oxford invention<br />

overcomes the problem by<br />

detecting image features based<br />

on the shape of the intensity<br />

profile of the feature, rather<br />

than just its intensity<br />

Conventional methods for enhancing such noisy images<br />

have relied on examining the intensity of the image, for<br />

instance by smoothing the intensity to reduce noise or by<br />

setting a detection threshold based on amplitude.<br />

However, these conventional thresholding techniques suffer<br />

from the difficulty of setting a suitable global threshold for<br />

the image that will reduce noise yet retain all the features of<br />

interest.<br />

Reproduced from the Quamus ® software package (an<br />

The Oxford invention overcomes the problem by detecting<br />

image features based on the shape of the intensity profile of<br />

the feature, rather than just its intensity. This is achieved by<br />

an intensity independent comparison of the intensity profile<br />

across the image with a shape model of features of interest.<br />

Subsequent image processing is further improved using a<br />

feature labelling process to describe the feature’s properties.<br />

The label can include such information as feature orientation,<br />

or velocity of features in image sequences. By setting the<br />

shape model appropriately the invention is adaptable to the<br />

detection of any features corresponding to a step change in<br />

intensity, such as accurate identification of ventricular walls<br />

in echocardiograms.<br />

By applying the same force and distortion to the tissue<br />

during the scan, change in shape during the scan can be<br />

prevented. A mechanical sweep probe, or constraining the<br />

target object and scanning through a window rather than<br />

making direct contact with the skin will achieve this, but the<br />

scan geometry is limited in both cases limiting their usefulness<br />

in clinical diagnosis.<br />

The Oxford development constructs a scan that would have<br />

been produced if there had been no contact between the<br />

skin and the probe. Using an elastic model specified a priori<br />

the method corrects the deformation applied by the probe,<br />

providing more accurate reconstruction and improved<br />

compounding performance.<br />

Improved Ultrasound Imaging<br />

– Project 1095<br />

To create an ultrasound image the ultrasound probe must be<br />

placed in contact with the skin. This contact force, although<br />

small, is sufficient to distort the skin and soft<br />

tissues beneath. Correction of this contact deformation is<br />

important when the tissue geometry must be known<br />

accurately such as in image guided surgery and in 3D ultrasound<br />

where several 2D images are acquired at different<br />

positions in a volume of tissue. The tissue will only be<br />

accurately reconstructed if its shape is the same in each scan.<br />

Combining or compounding these scans makes an assumption<br />

of constant tissue shape, but if the tissue has been distorted<br />

differently in each scan direct compounding of the<br />

data sets leads to a blurred image.<br />

Unusually, the inventions presented here exist in an implemented<br />

software form (Figure 2), the result of collaboration<br />

between Oxford University and Mirada Solutions. This work<br />

is covered in four patent applications and <strong>Isis</strong> <strong>Innovation</strong> is<br />

currently seeking partners to exploit this technology.<br />

Brain connectivity mapping<br />

<strong>Isis</strong> Project 1341<br />

A new and simple method that allows the creation of a<br />

dataset by mapping MRI brain scans of individuals with<br />

brain disorders has been developed and can be used to<br />

determine a pattern of connectivity for certain conditions<br />

such as schizophrenia enabling a better, more accurate<br />

diagnosis of the condition and therefore an improvement in<br />

treatment targeting accuracy and outcome.<br />

The unique connectivity pattern of a brain region<br />

determines the type of information available to it, and<br />

hence influences its function. Defining these patterns<br />

enhances our knowledge of human brain architecture and<br />

function. Non-invasive in vivo definition of brain<br />

connectivity patterns complements functional imaging<br />

and provides new understanding of disorders associated<br />

with developmental or regional alterations of brain<br />

connectivity. There are extensions to this approach to<br />

clinically important issues. As an example, brain<br />

connectivity problems are important in developmental<br />

and acquired brain disorders.<br />

Researchers working within the University of Oxford Clinical<br />

Neurology Department have developed a technique that is<br />

able to provide non-invasive identification of boundaries<br />

between major nuclei in a patient undergoing surgery,<br />

thereby improving both targeting accuracy and outcomes.<br />

The invention relates to mapping the connectivity of the<br />

brain’s nervous system in a human and uses imaging data<br />

derived from magnetic resonance imaging. New computer<br />

methods derive the anatomical connectivity patterns and<br />

analyse the structure of the nervous system.<br />

Testing the hypothesis that changes in fronto-thalamic<br />

circuitry i.e. thalamic dysfunction is a factor in schizophrenia,<br />

becomes a reality using this methodology. Impairments in<br />

cortico-cortical connectivity are found in individuals with<br />

learning disabilities.<br />

The new method allows a quantitative approach to the<br />

differences so that actual variations in learning abilities and<br />

performance can be determined. At present localisation in<br />

stereotactic neurosurgery or deep brain stimulation of<br />

specific thalamic nuclei in movement disorders remains<br />

difficult. This approach to grey matter segmentation has the<br />

potential to improve targeting accuracy and outcomes.<br />

Thalamus – connectivity pattern dataset.<br />

The invention relates to<br />

mapping the connectivity of<br />

the brain’s nervous system in a<br />

human, and uses imaging data<br />

derived from magnetic<br />

resonance imaging. New<br />

computer methods derive the<br />

anatomical connectivity<br />

patterns, and analyse the<br />

structure of the nervous system<br />
