Summary of the impact
Diabetes research at University of Ulster (Ulster) addresses the unmet
need of industry for new and more effective commercially applicable
approaches for diabetes therapy. We have generated a new class of
innovative peptide therapeutics resulting in a strong portfolio of
intellectual property, significant international recognition, financial
investment and job creation, with commercialisation through Ulster's
technology transfer company, Innovation Ulster (IUL), and the Ulster
start-up company, Diabetica Ltd. Our substantial interactions with
industry have resulted in the licensing and further development of our
international patents on stable incretin peptides for diabetes and,
through our discovery of their positive effects on cognition, for
treatment of Alzheimer's disease. This work has provided industry with new
and commercially viable approaches to significantly improve the lives of
people with diabetes and related neurodegenerative disease.
Underpinning research
The Diabetes Research Group (DRG), located in the purpose built SAAD
Centre for Pharmacy & Diabetes at Ulster, has a strong track record of
preclinical drug discovery and development, involving basic laboratory
work, both in vitro and in vivo. The key researchers
involved in this case study are Professor PR Flatt, Professor FPM O'Harte,
Professor VA Gault and Dr N Irwin who were all employed full-time at
Ulster at the time that the research was carried out from 1998 onwards.
The exploitation of DRG research findings is supported by IUL which, in
conjunction with the Ulster start-up company Diabetica Ltd., oversees the
management of our IP portfolio, on-going liaison with industry as well as
commercialisation of research outputs. The results of this research have
also been published in top peer-reviewed journals.
There is a continuing and unmet need for new drugs to counter the
epidemic of type 2 diabetes, obesity and related complications. Our
research has focused on the development of novel peptide therapeutics
based on peptide hormones secreted from the gut in response to nutrient
ingestion, most notably glucagon-like peptide-1 (GLP-1), gastric
inhibitory polypeptide (GIP) and cholecystokinin (CCK). These hormones
play an important physiological role in the regulation of feeding, insulin
secretion and blood glucose control. In the late 1990s, we discovered that
N-terminal glycation of these hormones prevented their degradation and
enhanced bioactivity so that they could be used potentially for treatment
of obesity-related type 2 diabetes (for GIP see [1]). We went on to
develop a strong series of anti-diabetic N-terminally modified enzyme
resistant analogues of GIP, GLP-1 and CCK8 using amino acid substitutions
plus possible additional acylation or mini-PEGylation modifications to
further extend half-life and therapeutic utility [2-6]. Early IP space for
GLP-1 was taken by industry but by 2008 we had secured world-wide patents
for analogues of GIP and CCK-8 consisting of 3 patent families covering 14
granted patents in the USA, Canada and Europe. In generating GIP agonists,
we developed antagonists such as (Pro3)GIP which unexpectedly turned out
to represent an entirely unexpected and new potential class of
anti-diabetic agent, acting through weight loss and the alleviation of
obesity-related insulin resistance and beta cell rest [3,4]. Recently, we
discovered that these novel GIP and GLP-1 peptides cross the blood-brain
barrier, activate hippocampal G-protein coupled receptors and reverse
defects of cognition in high fat fed, obese-diabetic mice and in
transgenic animal models of Alzheimer's disease, making the above
mentioned peptide families strong candidates for the treatment of
neurodegenerative disease (for GLP-1 see [5], patents granted and
pending).

Details of the impact
Innovative research described in this Case Study has led to generation of
a strong portfolio of IP including the granting of 12 patents since 2008,
which themselves demonstrate that our scientific discoveries have hit the
impact target of fulfilling the minimum legislative criteria of being non-
obvious, novel and capable of being applied in trade/industry. Outcomes of
our scientific discoveries also include the attraction of venture capital
funding and other investment, formation of the start-up company Diabetica
Ltd and creation of 3 jobs together with substantial productive and
on-going interactions with industry (see Section 5). Our activities have
influenced drug discovery programmes and development of clinical product
pipelines in major pharmaceutical companies worldwide (see Section 5 for
Testimonials). We have also undertaken significant contract research with
[text removed for publication] on incretin mimetics
and GIP antagonists, employing 2 other post-doctoral scientists.
Our IP on GIP agonists was licensed by IUL/Diabetica Ltd. to Amylin
Pharmaceuticals Ltd (now BMS) in March 2006, [text removed for
publication]. This includes 2 patent families covering GIP analogues as
treatments of diabetes, obesity and related metabolic disease, with 11
granted patents, including 4 in USA and Canada since 2008. As testimony to
our impact in this field, GIP agonists are now pipeline products of Ipsen,
Eli Lilly, and Amylin (now BMS) targeted for full clinical development as
evidenced by their more recent IP filings. Highly positive results of late
preclinical work on N- terminally modified GIP agonists have been
published recently by Amylin (BMS) scientists (Tatarkiewicz et al,
Diabetes Obes Metab. 2013 Jul 16, doi: 10.1111/dom.12181; see Section 5).
We have executed separate evaluation licenses for our IP on GIP
antagonists for the treatment of obesity-insulin resistance, to [text
removed for publication]. Our ground-breaking research has also driven
industry to make their own IP filings and undertake related drug
development on GIP receptor antagonists, including Ipsen, Amylin, Sanofi
Aventis and Zealand Pharma. Further, Zealand has recently announced a
partnership with Lilly to optimise new peptide candidates for diabetes. As
clear evidence of impact, our IP has been cited against their patent
filings, being included in numerous International search reports as `prior
art'. Further, we have now partnered with the field leader, [text removed for publication], to develop receptor-specific
peptidergic therapeutic GIP antagonists through a Research Collaboration
Agreement executed on 21/09/12.
We were also early leaders in the development of GLP-1 therapeutics,
where our innovative approach and published work informed the field of the
significant potential of the GLP-1 receptor as an important drug target.
Indeed, GLP-1 mimetics now represent a major success story in diabetes
therapy. Furthermore, our subsequent discovery and patent filing of stable
GLP-1 and GIP therapeutics for neurodegenerative disease has resulted in 6
granted EU patents since 2012 with a further 7 pending in Europe, USA,
Canada and Japan. This IP is being further co-developed under a Research
Collaboration and License agreement with [text removed for publication] executed on 8/3/12. In addition, [text removed for
publication] has also contributed [text removed for publication] awarded
by Alzheimer Society for a clinical trial of liraglutide (stable GLP-1
mimetic) in patients with Alzheimer's disease, which is currently
recruiting for patients. As a result of our research, other pharmaceutical
companies with GLP-1 agonists in their pipeline, [text removed for
publication] are also now exploring stable GLP-1 for treatment of
neurodegenerative disease.
Inherently drug development is a lengthy and perilous process, with low
success rate. In this context, the achievements described above plus our
significant contract research with industry on the development of GLP-1
and GIP mimetics are significant indicators of impact. More recently, we
have focussed attention on preclinical development of stable CCK-8
therapeutics for obesity and associated metabolic disease [6], with 7
granted EU patents, plus 2 further patents granted in USA and Canada since
2008. Our data have been replicated independently by a commercial CRO and
we have engaged with more than 30 potential industry partners and executed
2 contractual agreements ([text removed for publication]) to progress
commercial development.
A significant contribution to this case study stems from the formation
and subsequent commercialisation efforts of Diabetica Ltd. which was
founded in September 2004 as University start-up Company. This Company was
registered in Northern Ireland under number NI051793, as a vehicle to work
alongside IUL to help commercialise technology generated by DRG. Initial
investment of near £1m was from IUL and the venture capital company Seroba
Bioventures, with subsequent employment of 3 personnel and turnover of
over £600,000 from 2004 to 2011. Academic founder members of Diabetica Ltd
(Professors PR Flatt, FPM O'Harte and NH McClenaghan (employed at Ulster
since 1998)) were winners of the prestigious inaugural Academic Enterprise
Awards (ACES) Europe for Life Sciences presented in Stockholm, December
2008. Diabetica Ltd. and IUL continue to work together in exploitation of
research conducted and interactions with industry.
Our work in the area of novel peptide therapeutics for diabetes and
interactions with industry has been recognised internationally also by
prestigious personal awards. Professor PR Flatt was elected Member Royal
Irish Academy (2006) and awarded Dorothy Hodgkin Lecture of Diabetes UK
(2007). Other prizes include Biochemistry Society Medal (Professor PR
Flatt, 2005), Endocrine Society Nordisk Medal (Professor FPM O'Harte,
2006) and European Association for the Study of Diabetes (EASD) Rising
Star (Professor VA Gault, 2009). Professor PR Flatt was also member of the
influential international working group of Juvenile Diabetes Research
Foundation Ltd (JDRF) formulating the 2013 roadmap for the direction of
future UK research funding in type 1 diabetes.
