Summary of the impact
A discovery that a tomato extract could help with healthy blood flow has
been translated into a functional food ingredient now marketed globally
via the spin-out company Provexis plc. Fruitflow® — Provexis' lead product
— is the result of findings by researchers at the Rowett Institute of
Nutrition and Health, now part of the University of Aberdeen, that
biologically active constituents in tomatoes inhibit blood platelet
aggregation: a known cause of heart attack, stroke and venous thrombosis.
In 2009 Fruitflow® was the first food ingredient to meet the requirements
of the European Food Safety Agency for products with a specific health
claim. Provexis — the University of Aberdeen Rowett Institute spinout — is
listed on the AIM market — the London Stock Exchange's international
market for smaller growing companies — has seen values of £14 - £60
million and secured co-development agreements with major international
partners, including DSM, Unilever and Coca-Cola. This case study
demonstrates the direct translation of research to produce a functional
food ingredient of interest to global market players.
The claimed impact therefore relates to development of new product,
which has received the first ever novel health claim (Article 13.5) from
the European Food Safety Authority, and is being marketed as novel food
ingredient globally by a multinational company.
Underpinning research
Underpinning research leading to the spin-out Provexis plc was carried
out at the Rowett Institute of Nutrition and Health, now part of the
University of Aberdeen, between 1998 and 2001 by Professor Asim
Dutta-Roy's team in the Lipids and Cardiovascular Health Group. Financial
support was provided by the Scottish Environment Executive Rural Affairs
Department.
Dutta-Roy's research interests included the aetiology of atherosclerosis,
the influence of nutrition in cardiovascular disease development, and
platelet involvement in these diseases. He began a screening programme in
1998, examining the effects of a range of fruit and vegetables on platelet
function. This work expanded to include aqueous extracts of herbs and
botanicals [1,2] which revealed aqueous tomato has far higher
anti-platelet activity than other extracts [3,4].
Further research localised the anti-platelet activity, conducted the
first investigations of mode of action, tested stability under various
conditions, and initiated work to identify the compounds with
anti-platelet activity. This work established that the bioactives were low
molecular weight, water-soluble, and heat-stable. The presence of
adenosine and cytidine was confirmed in the bioactive fractions, however,
these compounds alone did not account for the full bioactivity of the
extract. Platelet function experiments of the biologically activation
fraction revealed that more than one mode of action was likely. The
presence of a range of compounds suggested that all have anti-platelet
activity but act on different parts of the platelet activation/aggregation
pathway. The chemical properties of the active compounds indicated their
potential suitability as therapeutic agents or as functional food
ingredients.
The World Health Organization (WHO) estimates that annually worldwide
more than 15 million people suffer a stroke and that total mortalities
from all cardiovascular disorders (CVD) exceed 17 million (the Atlas of
Heart Disease and Stroke). Diet and lifestyle linked conditions such as
stroke and coronary heart disease account for 5.5 million and 7.2 million
deaths, respectively. Recent data has indicated that other conditions such
as deep venous thrombosis (DVT) affect approximately 8 in 10,000 in the
world population.
Whilst CVD is global it is more pronounced in developed countries (60% of
total burden) where CVDs account for 18% of Disability Adjusted Life Years
(DALYs) and estimated to equate to 82 million DALYs by the year 2020. The
cost of managing this burden is significant with CVD medication estimated
by WHO to account for approximately 12% of total healthcare budgets.
Therefore there are considerable commercial and public health drivers to
rationalise the use of high cost medication by exploring complementary
foods containing bioactive supplements and functional ingredients which
could be good for health. A 2009 PricewaterhouseCoopers report estimated
the US market for heart health functional foods to be worth $5 billion and
to be growing at almost 7% per year.
In 1999, sufficient data was available to file a patent application, and
a commercialisation strategy was initiated. A human trial provided
valuable proof of concept data to support this but showed that drinking 1L
of fresh tomato juice did not lead to anti-platelet effects, confirming
that a concentrated extract was necessary before efficacy could be
observed. This was published in the journal Platelets [3]. By
2001, the body of evidence amassed was sufficient to secure funding for
commercialisation. Provexis Ltd was formed, and a work programme commenced
focusing initially on characterisation of the extract, followed by
development of a prototype industrial extract.
This was followed from 2003 by extensive successive human trials to
demonstrate the efficacy of the extract, mechanistic work and full
industrial scale-up [6]. This work programme enabled construction of a
product-specific dossier in substantiation of a health claim, submitted in
2008; which was sufficiently detailed and evidenced to allow a favourable
landmark judgement from the European Food Safety Agency (EFSA) in May 2009
— the first product-specific (Article 13.5) health claim to be approved.
The award set a benchmark for other companies to follow and demonstrated
that the science led approach adopted by the small company could compete
successfully with the intellectual inputs of major global players. This
remains a definitive standard for the industry — since then very few other
companies have successfully gained similar approval.
The tomato extract developed by Provexis Ltd was given the trade name
Fruitflow® and is an established functional food ingredient, marketed
globally after European launch in November 2010 at the Health Ingredients
Europe Conference (Madrid). There the product won the `Most Innovative
Health Ingredient' award as well as best innovation in the `Heart Health'
category. Products containing Fruitflow® are already sold in a number of
major global markets.

Details of the impact
The original research and novel IP provided the springboard for the
establishment of a spinout company, founded jointly with the research
partner in 2001. Initial funding was provided by Angle plc, Rising Stars
Growth Fund and North West Equity Fund. In 2005 the company floated on the
LSE AIM market and its workforce increased in size to 13. Further funding
rounds in 2008 and 2010 enabled new projects to be initiated.
Over the development timeline of this product (2001-2010), Provexis has
had exclusive collaboration agreements with Unilever (12-month exclusivity
agreement 2006, long term development agreement 2007-2009); The Coca-Cola
Company (2007-2009), and non-exclusive development programmes with Nestlé
and Cargill. Provexis plc's share price doubled between January and April
2012. The company now employs over 20 specialist staff at its business
operations site in Windsor, its manufacturing plant in Nelson, Lancashire
and until recently (April 2013) maintained research laboratories at the
Rowett Institute in Aberdeen.
An alliance agreement was announced with DSM Nutritional Products in June
2010, to commercialise the Fruitflow® heart-health technology. The
Alliance gave DSM exclusive global rights to Fruitflow® — a basis for
collaboration between the partners and the development of Fruitflow® in
all major global markets. The Alliance partners have now worked to develop
a powder concentrate of the Fruitflow ® technology, which is being readied
for tablet and capsule use. Under the terms of the alliance, DSM is
responsible for manufacturing, marketing, and selling via its global sales
force, while Provexis remains responsible for contributing the scientific
expertise necessary for successful commercialisation. In 2010 it was given
awards for the "Most Innovative Health Ingredient" and the "Best
Innovation in the Heart Health" category at the Health Ingredients
European Conference (Madrid). In 2011 it was awarded the Nutraward for
"Best New Ingredient" at the USA trade launch at the Nutracon conference
(Anaheim, California).
Fruitflow® is currently incorporated into eight marketed products
worldwide including Europe, North America and Asia. In the UK it is
available in Sirco®, a fruit juice drink, which is sold through a series
of outlets and supermarkets including, Sainsbury's, Waitrose, Ocado,
Amazon, Holland & Barrett and EH Booth Supermarkets. In the USA it is
available, for example, in products produced by Swanson Health Products
USA and Relaxzen, USA, and in China by Bankom Ltd as Fruitflow®.
Provexis had moved to increase its footprint in the functional food
sector by taking over a company specialising in functional ingredients for
sports nutrition, Science in Sport (SIS) (www.scienceinsport.com).
It has signed a new 5-year deal to continue as Official Supplier of Sports
Drinks and Sports Nutrition of the GB Rowing Team for Senior, Adaptive and
Top Development rowers providing a range of nutritional products for
hydration, energy and recovery.
In January 2013 SIS launched REGO+ Fruitflow ®, the first product of its
kind designed to help endurance athletes improve recovery time after
intense exercise (http://www.scienceinsport.com/sis-products/sis-rego-range/sis-rego-plus-fruitflow-gels/).
The companies have since demerged into two separate entities, with
continuing marketing of the Fruitflow based products.
Building on the original work by Professor Dutta-Roy's team, new research
has generated novel intellectual property covering different therapeutic
areas, as well as different compositions, with several further patents
obtained. Several applications have now gone to grant in territories
worldwide, underlining the novel and innovative qualities of both the
original and subsequent research in particular in the cardiovascular and
inflammation areas.
Furthermore, in April 2011, EFSA issued a set of draft guidelines
(http://www.efsa.europa.eu/en/consultations/call/nda110426a.pdf)
to inform applicants of acceptable categories of health claim, as well as
biomarkers/methods of analysis which would be accepted in dossiers. Health
claims related to platelet function are included as an accepted category
in these draft guidelines, currently open for public consultation. The
approval of the Provexis health claim submission (the only submission of
this type) was key to the inclusion of this category in the draft
guidelines. This will be of benefit to the food industry for future
submissions http://ec.europa.eu/food/food/labellingnutrition/claims/community_register/authorised_health_claims_en.htm#art135).
Claimed impact as defined by REF: This work has therefore had impact
on commerce through creation of a new spin-out business with leverage of
significant external commercial investment, successful creation and
manufacture of a new product and creation of other commercial activity,
contracts, and business performance.
