This is an exciting project that, with the international group’s extensive research and know-how in mind, has the potential to create an intriguing base for novel personalised treatments for atopic dermatitis (AD). The project moreover holds an innovation potential that may make it stand out in the emerging global bio-economy.
The prevalence of AD, an inflammatory skin disease resulting in itchy, red, swollen and cracked skin, is constantly increasing. Today, it affects 15-30 percent children and 2-10 percent adults worldwide, presenting a significant economic burden to healthcare systems.
There is no cure for AD, only soothing of the symptoms. In the majority of AD patients, the disease is a consequence of a blend of genetic defects of the skin barrier defects and abnormal immune responses influenced by environmental factors.
Until now, the models used to assess the interplay are not particularly predictive. The group behind this project aims to change this by using the latest advances in stem cell science, gene editing and tissue engineering to develop and validate innovative 3D in vitro models of skin – making the models similar to skin in AD patients by emulating full thickness skin of varying barrier integrity; faulty, partially repaired or intact, and immune response composition.
As part of the project, the group will also develop mathematical computer models to accurately address the predictive, prognostic and therapeutic outcome of personalised AD therapy – in order to address co-dependence of the quantitative and qualitative changes in skin barrier and activation of immune cells.
The 3D models will also be made available to test various novel therapeutic approaches for AD treatment in a patient specific manner.

Melanocyte stress response pathways and their role in the onset of vitiligo

Grant category: Research Grants in open competition
Year: 2016
Geography: USA
Vitiligo, an acquired skin disease in which pigment cells, melanocytes, are destroyed, affects 1-2% of people worldwide. The disease deprives the skin of photoprotection leaving it more susceptible to solar damage and compromised cutaneous immunity – and the disease impacts physical and mental health.
Vitiligo is thought to occur in genetically susceptible individuals after being exposed to environmental triggers. Some individuals develop contact vitiligo after direct exposure to certain chemicals. As disease progression in vitiligo is independent from initiating factors, this subset of individuals makes it possible to study vitiligo at large.
The hypothesis in this project is that melanocytes from healthy individuals can withstand exposure to triggers by initiating a stress response regimen that allows the cell to return to homeostasis. These pathways may be disrupted in individuals who develop vitiligo, leaving melanocytes stressed following challenge, causing them to be targeted for removal by the immune system.
In order to investigate this hypothesis, the project will investigate survival pathways in melanocytes cultured from biopsies taken from pigmented skin from individuals who have developed vitiligo.
Development and validation of scoring systems for outcome measures of vitiligo: an international cooperative initiative
Grantee: Professor, Dr Nanja van Geel, Department of Dermatology, Ghent University Hospital, Ghent
Amount: DKK 735,000
Grant category: Research Grants in open competition
Year: 2016
Geography: Belgium
Clinical trials for vitiligo – a skin disease that causes loss of skin color in blotches – lack uniformity in reported outcomes and the measurements hereof. This lack of uniformity hampers development of general treatment guidelines, as it limits appropriate interpretation and comparison of results. In particular, since vitiligo is without biomarkers, clinical measurement tools are crucial to assess disease extent.
A recently introduced scoring instrument, Vitiligo Extent Score (VES), will play a central role in this international project. The project team comprises researchers from Belgium, Netherlands, France, Italy, and the UK, and their aim is to create a worldwide consensus on measuring disease severity.
The VES was designed to be intuitive, fast and accurate, and the team has successfully performed an initial validation for estimating global disease extent. The aim of this project is to further develop and validate reliable and feasible instruments to assess vitiligo status in order to improve evidence-based therapeutic decisions and develop novel treatments.
Hereafter, the tool will be used for the development of other scoring methods including a patient-reported outcome measure, a physician global assessment, a vitiligo disease activity score, and a digital image analysis system for target lesions.

In March 2016, the IEC will hold a session at the Annual AAD in Washington, D.C. focusing on AD phenotyping – starting to use biomarkers to assess subgroups of AD, which may be relevant to the understanding of disease and treatment decision-making.
Development and validation of a physiologically-based pharmacokinetic model for dermal absorption
Grantee: Dr. Richard H. Guy, Professor of Pharmaceutical Sciences & Dr. M. Begona Delgado-Charro, Associate Professor of Pharmaceutics, University of Bath
Amount: DKK 3,564,000
Grant category: Research Grants in open competition
Year: 2016
Geography: United Kingdom
The project aims to develop a physiologically based pharmacokinetic model to predict the dermal absorption and disposition of drugs included in complex topical products.
A distinctive feature of the research is the integration of formulation-dependent information derived experimentally, and a deliberate strategy to facilitate the practical implementation of the model for a wide range of drugs.
The long-term goal is to develop a model, which will predict drug absorption and disposition from dermal products thereby facilitating their optimisation and, ultimately, the development of high-performance medicines.

The natural history of skin cancer formation: from normal skin to cancer
Grantee: Associate Professor Kiarash Khosrotehrani, University of Queensland
Amount: AUD 268,239
Grant category: Research Grants in open competition
Year: 2015
Geography: Australia
Associate Professor Kiarash Khosrotehrani from The University of Queensland leads a team that has hypothesized that upon UV irradiation and acquisitions of mutations, only epidermal cells that can rapidly proliferate are likely to give rise to pre-cancerous and cancerous lesions.
This hypothesis will be tested using multicolour lineage tracing to follow simultaneously multiple epidermal clones that will further be microdissected to establish their mutational profile. This study has the potential to fundamentally change our understanding of field cancerisation, cell of origin of squamous cell cancer establishing potentially new therapeutic targets.
Preventing Basal Cell Carcinoma formation by targeting the tumor environment
Grantee: Associate Professor Kiarash Khosrotehrani, University of Queensland
Amount: AUD 415,386
Grant category: Research Grants in open competition
Year: 2015
Geography: Australia
In this study, Associate Professor Kiarash Khosrotehrani of The University of Queensland in Australia proposes to better characterise the molecular nature of the factors provided by fibroblasts to support basal cell carcinoma (BCC) growth in vivo in order to find new targets for therapies that would prevent BCC development. He and his team will also show proof of principle demonstrating that targeting this process can actually prevent BCC development.
These findings have the potential to translate in effective prevention strategies, allowing field therapy of normal looking skin to avoid the development of new BCCs. Such finding will have strong health benefits in terms of morbidity associated with multiple surgeries, years of healthy life enjoyed by individuals and finally in terms of economic cost.
