The Pursuit of Better Medicines through Genetic Research

Terri Arledge, DVM

US Department Head

Drug Development Genetics

slide2

Genetic research goals and initiatives at GSK

  • Industry group addressing ethical, legal and regulatory issues with genetic research into drug response (pharmacogenetics)
  • Research sponsor’s perspectives on family consent and suggested points to be considered
slide3

Genetic Research Goals at GSK

  • Identify susceptibility genes for common diseases
  • Use results of genetic research to discover new medicines acting on new targets (e.g., new genes associated with human disease pathway)
  • Improve safety and efficacy of medicines by understanding the genetic basis for +/- drug response in individuals
  • Promote education and informed discussion about genetic research

Identification of Disease Susceptibility Genes

  • Susceptibility genes confer a risk of - but do not cause - disease
  • GSK Clinical Genetics Networks
  • Large, international studies among academic institutions, genome screening centers and genetic epidemiology centers
  • Protocols with well-characterized, standardized patient assessment criteria
  • Detailed family history, clinical information and DNA from affected and unaffected siblings and parents
  • Informed consent and information coding
  • Identify gene loci responsible for disease susceptibility
  • Examples -- Asthma, Depression, COPD, Early Onset Heart Disease, Osteoarthritis
slide6

Pharmacogenetic Research

  • Pharmacogenetics: How genetic differences among patients influence their responses to medicines
  • GSK’s Pharmacogenetic research in drug development trials
  • Participation is voluntary - separate consent for genetic research
  • Blood sample for DNA analysis and information coding
  • Correlate drug response with genotype information using pooled data

Pharmacogenetics Working Group

Mission: To advance the understanding and development of pharmacogenetics by openly addressing and disseminating information on non-competitive topics such as ethical, legal and regulatory issues.

Proposed Activities: Sponsor symposia, prepare publications, interface with US and European regulators and address elements of pharmacogenetic research protocols and consents

slide9

A Sponsor’s Perspectives on Family Consent

  • Distinction among types of research
  • Implications for Study Participants
  • Implications for the Feasibility of Research
slide10

Points to Consider regarding Family Consent

  • Scientific rationale for collecting family history data
  • Justification for the degree of detail
  • Degree of confidence that subject is a credible source of family history
  • Implementation of safeguards (data collection environment, access and release of data)
slide11

Recommendations regarding Family Consent

  • Responsibility for assessing family consent issues should remain with local investigators, ethics committees and research sponsors
  • Education and guidance materials - not prescriptive, sweeping measures - should be developed for use by researchers, ethics committees and sponsors
