Integrated Analyses of Safety Data needed!

Agenda

Integrated Safety Outputs (ISOs):

  • Regulatory purposes
  • Signal Detection
  • Presentations: Consistency and Clarity
  • Risk Management Plans (RMPs)

MedDRA:

    • Standardised MedDRA Queries (SMQs)
the issue
The Issue
  • Applications and regulatory documents only summarize the safety database
  • Statisticians today only analyse safety data acrosstrials, when:
    • Potential problems arise or
    • The application is for a product from a class with a known safety concern

Future

  • Health Authorities require more regular integrated safety analyses
purpose of integrated safety outputs
Purpose of Integrated Safety Outputs

Many regulatory documents require reporting of safety information:

  • IND Annual Report (FDA)
  • Annual Safety Report (EMEA)
  • Investigator’s Brochure
  • Risk Management Plans
  • DMC Data Packages
  • Investigational Medical Product Dossier (Risk/Benefit)
  • Integrated Safety Summary – CTD
integrated safety outputs
Integrated Safety Outputs
  • Regular Integrated Safety Reviews
    • To be produced at least annually
    • Pool or combine data across studies
    • Present data from several studies in a single display
  • Gain
    • Provide coordinated and routine review of integrated safety data
    • Assist with the compilation of regulatory documents reporting safety information/ DMC data/RMP updates etc.
considerations for pooling or combining data
Considerations for Pooling or Combining Data

Main goal

  • More precise estimates by increasing the safety database

In general, ISO produced by indication or formulation:

  • Backgound AE may differ according to patient population
  • Severity of disease may lead to different assessments of risk/benefit
  • The dose, formulation and duration of treatment may differ

Across indication/formulations beneficial:

  • Investigational product developed for related indications
  • Characterize a particular AE of interest
  • Investigate class effects
the ae profile may be related to
The AE profile may be related to…
  • Route of administration
  • Dose
  • Number of dosages
  • Duration of exposure
  • Time since dosing
  • Indication
  • Stage of disease treated
  • Concomitant medication/disease
  • Effect on target cell/organ e.g. B-lymphocytes
  • Demography
signal detection
Signal Detection
  • No systematic tools or methods in use within the industry
  • Need to account for all safety data, not just AE records
  • Monitor laboratory results for an increase in abnormalities
      • Currently done manually, more efficient and consistent with standard checks pre-defined and applied to all studies
  • Focus on three main areas (the most common reasons to terminate projects):
    • Hepatotoxicity (Liver)
    • Nephrotoxicity (Kidney)
    • Haematotoxicity (Blood)
operational issues
Operational Issues
  • Maintenance of treatment blind
    • Should not be an impediment to a full ongoing review of safety data?
  • Who should have access to data and results?
  • Should DMCs review un-blinded data?
  • False signals
    • Problem or proactive pharmacovigilance?
  • A policy for ’Integrated Safety Outputs’ should be prepared
risk management plans rmp
Risk Management Plans (RMP)

The overall purpose of a Risk Management Plan is to describe efforts in:

  • Identifying
  • Estimating
  • Evaluating
  • Communicating
  • Minimising

risks that may be associated with the product.

risk management plans
Risk Management Plans

EMEA:

  • Guideline on Risk Management Systems for Medicinal Products for human use
    • Effective date 20 November 2005

FDA:

  • Guidance for Industry: Good Pharmacovigilance Practices and Pharmacoepidemiological Assessment
      • Pre-marketing Guidance
      • Pharmacovigilance Guidance (postmarketing)
      • March 2005
risk management plans12
Risk Management Plans
  • Be product-specific
  • Balance assessment of risks and benefits
  • Monitor difference between clinical trials and ”real life”
  • Identify what is known at licensing
  • Identify what is not known
  • Clarify epidemiology of disease and known adverse effects
what we know and don t know
What we know and don’t know

Know:

  • Population treated
  • Time treated
  • Time to adverse events
  • Identify specific risk groups
  • Stratify analysis by dose, duration etc

Don’t know:

  • Interactions
  • Populations not studied: Children, elderly, pregnancy
  • Relevance of class effects
  • Long term effects
when do we need a risk management plan
When do we need aRisk Management Plan?

When initiating trials in

  • New active substances
  • New indications – incl extension to a different population
  • New routes/formulations
standardised meddra queries
Standardised MedDRA Queries
  • After the initial effort to implement and use MedDRA, the industry now focuses on data analysis with MedDRA
    • How to produce data summaries based on a more granular terminology
  • Standardised MedDRA Queries (SMQs):
    • Groupings of MedDRA terms that are related to a defined medical condition
    • Include terms related to signs, symptoms, diagnoses, syndromes, physical findings, laboratory test data
standardised meddra queries16
Standardised MedDRA Queries
  • Developed in a collaboration with CIOMS, industry and regulators

(Council for International Organizations of Medical Sciences, WHO and UNESCO in 1949)

  • Tested in industry and regulatory databases
  • Focus on significant safety issues
  • Currently, 16 in production and 70 in development
