Periodic Reporting for period 2 - BIOMAP (Biomarkers in Atopic Dermatitis and Psoriasis)
Reporting period: 2020-04-01 to 2021-03-31
Beyond their significant skin manifestations, both AD and Pso are associated with strongly increased risk of other conditions (so-called comorbidities); up to one-third of people with AD suffer from another allergic disease (food allergy, rhinitis, asthma) and around 20% of people with psoriasis are affected by psoriatic arthritis. Other problems such as inflammatory bowel disease, heart disease and mental health disorders are common to both AD and Pso. Despite significant progress in the clinical and scientific understanding of AD and Pso, at present, the precise mechanisms driving onset and course are poorly described, disease progression and/or the development of comorbidities are unpredictable, and the optimal type and time-point for intervention is as yet unknown.
The overarching remit of BIOMAP is to develop patient-focused understanding of AD and Pso, and to define factors influencing the heterogeneity and trajectory of the patient journey. We have created a consortium built on sharing of existing data from a wide variety of research studies, including detailed clinical evaluation, genetics, molecular analysis of tissues and microbes, and ethical and biomarker insights that can support the future of disease understanding and therapeutic development. More specifically, BIOMAP aims:
• To establish a pan-European BioResource for research into inflammatory skin diseases through alignment of clinical data with archived and newly obtained biological specimens for investigations into molecular mechanisms of disease.
• To build a Data Warehouse assimilating existing and incoming clinical, experimental and multi-omics data from large high-quality patient collections, disease registries, epidemiological cohorts and industry trials with immediate access for analysis through a Data Analysis Portal, enabling users to investigate interactions between clinical features and molecular pathways, and to define disease subtypes.
• To establish a collaborative network of clinicians, researchers and industry along with patient organisations and other major stakeholders (a European clinical research network) to work in a co-ordinated way to refine clinical definitions and to define relevant and patient-centred outcomes, harmonise longitudinal recruitment, deep clinical evaluation and high-quality bio-sampling to address gaps in the BioResource, and to optimise the translational potential of BIOMAP.
• To identify influential life events and environmental factors, and to generate predictive models and biomarkers of relevant disease outcomes (e.g. severity, progression, comorbidity development, therapy response) to guide patient management, and to direct therapy development and stratifiers for use in trials;
• To cross-reference findings from AD and Pso to look at similarities and differences that could be used to refine definitions of disease subtypes and/or inform selection of targets for therapy.
• The technical infrastructure for data collection, integration and analysis of all the data to be used in BIOMAP has been established (the BIOMAP Data and Analysis Portal) and has been populated with publicly available data. A robust and secure data management plan has been developed along with detailed guidelines and governance framework for data upload, storage and access. Legal documentation has been put in place to enable data sharing between the partners in full compliance with applicable regulatory guidelines, including the General Data Protection Regulation (“GDPR”). Novel tools and analysis methods to enable fast, efficient investigation of clinical and molecular data has been made available to all BIOMAP partners through a user-friendly interface.
• The pan-European bioresource is available to BIOMAP researchers with supplementary samples being collected at multiple European sites. The technical platform for managing access to and transport of, samples (the Virtual Biobank) has been finalised.
• The BIOMAP Glossary for harmonisation of clinical data has been published and has the potential to benefit future investigators, who may prospectively align their studies with the Glossary’s clinical variables, facilitating future comparative analyses beyond the BIOMAP consortium.
• Several research papers describing molecular signatures associated with AD and Pso activity as well as the microbe-host interplay in AD and Pso have been published.
• Novel techniques for identifying and analysing skin and blood cells at a single-cell level have been developed and deployed in patient samples for both AD and Pso patients.
• A first large-scale population-based analysis on factors modulating the skin microbiome has identified key environmental impacts; a first research paper has been published, and a second one is in preparation.
• Classification of AD and Pso disease subtypes using data on microbial populations present on the skin (the „skin microbiome”) is underway.
