Rare Diseases PeculiaritiesDISADVANTAGE no or little evidence available small populations , scattered coding and classification poor no jurisdiction , or country with

sufficient data require collective data and case

finding for evidence not all rare diseases are the same in

terms of evidence: e.g. Cystic Fibrosis ≠ Progeria

orphan therapies fail the cost effectiveness threshold

ADVANTAGE Clarity in the extreme Phenotype:

– genotype atomise disease; – permit re-aggregation based on

pathways perturbed, not clinical presentation

New knowledge translation and the portal to Individualised medicine

Satisfaction for professionalsFrustration for patients

Anxiety for payors Slow translation from bench to bedside

Limited access to innovations Too few treatments compared to needs

Most patients feeling abandonned High cost of diagnostic tests and drugs

Not affordable Necessity to de-risk research

Cheaper R&D

INITIATIVES TO SPEED UP DATA SHARING

20

Page 21: Research Infrastructures  to boost R&D  in the field of rare Diseases

Rational

Research produces an enormous amount of data If shared, will facilitate the development of diagnostics and

treatments while ensuring efficient utilization of scarce resources

Resources include patient and family material (extracted DNA, cell lines, pathological samples), technical protocols, informatics infrastructure, and analysis tools

Datasets include phenotypes, genomic variants, other ‘omic’ data, natural histories, and clinical trial data…

21

Page 22: Research Infrastructures  to boost R&D  in the field of rare Diseases

Barriers to Data Sharing Technical and Financial issues

Storing terabytes…Securing dataProviding the logistics for sharing dataStatistical and algorithmic issues to combine datasets

Ethical and Legal issuesData across public and private networksPricacy protection at national level

Cultural issuesReluctance to share data from researchers/

Institutions/Regulatory bodies

22

A ClearingHouse of Data Standardsis in development at IRDiRC

Five main fields of application Standards in Genomics and other OMICS Standards in Phenotyping Standards in Outcome Measures for clinical trials Standards in Human Data Registration Open-access Data Repositories to store data

Rational

Make the most of remarkable advances in the molecular basis of human diseasesdissect the physiological pathwaysimprove diagnosisdevelop treatments

Make rare diseases visible in health information systems to gain insight into themto access real life data already collected

Improve coding of RD whichever coding system used Cross-reference coding systems: Orpha nomenclature, ICD10, MeSH, SnoMed-CT, MedDRA

Orphan Diseasome

http://research.cchmc.org/od/01/index.html

An Orphan Diseasome permits investigators to explore the orphan disease (OD) or rare disease relationships based on shared genes and shared enriched features (e.g., Gene Ontology Biological Process, Cellular Component, Pathways, Mammalian Phenotype).

The red nodes represent the orphan diseases and the green ones the related genes. A disease is connected to a gene if and only if a mutation which is responsible of the disease has been identified on this gene.

Page 31: Research Infrastructures  to boost R&D  in the field of rare Diseases

UMLS = Unified Medical Language System ICD = International Classification of Diseases

Since 1863 by WHO Used by most countries to code medical activity, mortality data

MeSH = Medical Subject Headings controlled vocabulary thesaurus used for indexing articles for PubMed by

National Library of Medicine (USA) SnoMed CT = Systematized Nomenclature of Medicine--Clinical Terms

clinical terminology by the International Health Terminology Standards Development Organisation (IHTSDO) in Denmark

Used in the USA and a few other countries MedDRA = Medical Dictionary for Regulatory Activities

medical terminology to classify adverse event information associated with the use of medical products

by the International Federation of Pharmaceutical Manufacturers and Associations (IFPMA)

Each terminology has a purpose–driven approach

Indexing health status of individual patients for health management (SnoMED) Detailed, focus on manifestations and complaintsAdapted to clinical habitsAnalytical approach

Indexing health status of individual patients for statistical purpose in public health (ICD)More agregated, interpreted phenotypic featuresAgregated conceptsUnambiguous to avoid blanks

Page 34: Research Infrastructures  to boost R&D  in the field of rare Diseases

Purpose–driven approach (2) Indexing health status of individual patients for clinical

research purpose (HPO / PhenoDB / Elements of morphology)Highly detailed to fit with the research questionsSpecific terminologies developed for disease-specific

patient registries Indexing health status of individual patients for retrieving

possible diagnoses (LDDB,POSSUM,Orphanet)Agregated concepts Requires a judgement of clinicians about phenomic

expressions that are relevantUnambiguous to avoid blanks

Phenotype terminology project• Aims:

– Map commonly used clinical terminologies

(Orphanet, LDDB, HPO, Elements of morphology,

PhenoDB, UMLS, SNOMED-CT, MESH, MedDRA):

• automatic map, expert validation, detection and

correction of inconsistencies

– Find common terms in the terminologies

– Produce a core terminology

• Common denominator allowing to share/exchange

phenotypic data between databases

• Mapped to every single terminology

Page 38: Research Infrastructures  to boost R&D  in the field of rare Diseases

Mapping Terminologies

• Orphanet: 1357 terms (Orphanet database, version 2008)

• LDDB: 1348 dysmorphological terms (Installation CD)

• Elements of Morphology: 423 terms (retrieved manually from

publication AJMG, January 2009)

• HPO: 9895 terms (download bioportal, obo format, 30/08/12)

• PhenoDB: 2846 terms (given in obo format, 02/05/2012)

• UMLS: (version 2012AA) (integrating MeSH, MedDra, SNOMED

CT)

Page 39: Research Infrastructures  to boost R&D  in the field of rare Diseases

Tools• OnaGUI (INSERM U729):

ontology alignment tool• Work with file in owl format• I-Sub algorithm: detect

syntaxic similarity• Graphical interface to check

automatic mappings and manually add ones

• Metamap (National Library of Medicine): a tool to map biomedical text to the UMLS Metathesaurus

• Perl scripts: format conversion, launching Metamap, comparison of results…

Page 40: Research Infrastructures  to boost R&D  in the field of rare Diseases

Comparison of mappings and deduction

• Perl script to compare all the mappings and infer mappings of non-Orphanet terminologiesEg: Orphanet ID XX mapped to YY in HPO and ZZ in LDDB -> deduction: YY and ZZ should probably map

• Retrieve HPO mappings versus UMLS, MeSH

• First figures:

available, and HPO/Stedman’s Medical Dictionary, if not List of terms, mapping to HPO, PhenoDB, Elements of

Morphology will be available at http://ichpt.org by January 2015.

All tools will map to this terminology to allow interoperability among resources

Workshop on Terminologies for RD – Paris, 12 September 2012

Many terminologies in use to describe phenomes - No interoperability

FROM A TERMINOLOGY TO AN ONTOLOGY

COMPUTERS ARE NOT SMART

45

Page 46: Research Infrastructures  to boost R&D  in the field of rare Diseases

Why ontologies are needed ?

Ontologies are representations of the knowledge in a way which is directly understandable by computers

Ontologies allow reasoning Ontologies define the objects AND the relationship

between the objectsDuchenne muscular dystrophy (disease) Is a neuromuscular

disease (group of diseases) Schistosomias (disease) Is a cause of anemia (manifestation)

Rational: Make optimal use of molecules already known

Drug Repositioning or Repurposing is a strategy used to generate new or additional value for a drug, by targeting diseases other than those for which it was originally intended Address unmet medical needs Reduce time to market due to provided information on Unbiased clinical safety and efficacy data Add value to exiting porfolio Increase drug pipeline Decrease R&D failure risks Decrease development costs Creates new revenue potential

Conclusion

Open access to dataWe now leave in an open worldIt is an opportunity in researchEvidence that open-access to data is beneficial, especially

for the data producer !Orphadata is accessed by 3000 researchers/ month

Agreed standards to make data interoperable Responsibility of Institutions and of individual

researchers
