Programme

Part I: General Strategies for Investigation and Control of Impurities on 01 December
 
Impurities Analysis and Qualification of Impurities in Drug Substances and Drug Products – General Overview
  •  Impurity profiling in synthetic drug substances
  •  Qualification of impurities
  •  Degradation studies
  •  Identification of chiral impurities, polymorphic phases and new impurities
  •  Residual solvents
  •  Impurities in starting materials and intermediates
  •  Pharmacopoeial tests and acceptance criteria
  •  Drug product specifications and parametric release
Analytical Method Validation for Impurities Determination at Various Development Stages
  •  Quantification of impurities
  •  How to define an impurity profile (stress tests)
  •  Reference substances
  •  Validation of methods at various development stages
  •  Statistical approaches to method validation (LOD & LOQ)
Presentation and Workshop: Analytical Techniques for Determination and Qualification of Impurities in Starting Materials and Intermediates
  •  Purity analysis by HPLC, impurity profile
  •  Residual solvents by GC
  •  Inorganic impurities (heavy metals, sulphated ash)
  •  For chiral compounds in addition: enantiometric purity and proof of the absolute configuration
  • In the Workshop the participants will learn which activities are necessary to characterize drug substances taking into account the following aspects:
  •  Analytical procedures are necessary for the characterization
  •  Experiments necessary to check the downstream impurities in order to justify acceptance criteria for the respective impurities
  •  Other impurities have to be taken into account
  •  Experiments to be performed in order to get a stability-indicating analytical procedure
Leachables and Extractables
  •  Why should Extractables & Leachables be assessed?
  •  Regulatory requirements in the EU and US
  •  Compendial requirements and  industry standards
  •  Safety qualification of Leachables and Extractables
Unexpected Impurities: Approaches for Investigation and Determination
  •  Is there such a thing as ‘unexpected impurities” or is there a lack of process understanding?
  •  Valsartan – overview of events
  •  Source of contamination
  •  Mechanistic understanding
  •  Examination of risk within other Sartans – overview of how to conduct a risk assessment and to identify key factors
  •  Are there other Mutagenic Impurities related risks?

Part II: Nitrosamine Impurities on 02 December
 
European Pharmacopoeia Activities (Policy) on Mutagenic Impurities with Focus on Nitrosamines
  •  Ph. Eur. General policy on DNA reactive impurities
  •  Control of Nitrosamines in Ph. Eur.
  •  Changes in individual and general monographs following the Sartan case
  •  New general chapter on control of nitrosamines
Root Causes for Nitrosamine Impurities and Other Mutagenic Impurities – Practical Approaches to Assess the Risks
  •  Development of a systematic risk based approach
  •  Key factors and the development of a decision tree
    •  API
    •  Drug Product
    •  Packaging
ICH M7 Safety Risk Assessment and the Cohort of Concern – How to Deal with e.g. Nitrosamines
  •  Principles of cancer risk estimation in ICH M7
  •  Why was the cohort of concern excluded from ICH M7?
  •  Applicability to use ICH M7 based cancer risk assessment to the cohort of concern
  •  Nitrosamines, why are they in the cohort of concern?
  •  Major risk factors for sources of nitrosamines in drugs
  •  Way forward to handle cohort of concern within ICH M7
Workshop:
Conducting a Risk Assessment
In this Workshop the participants will work on several case studies and perform a risk assessment for different scenarios taking into account e.g. manufacturing equipment, dosage form of the drug product etc.

Nitrosamines and Other Genotoxic Impurities – Authorities' Expectations and Dossier Requirements
  •  The assessor’s approach: principles of toxicological assessment
  •  Structural alerts
  •  Limits and Permitted Daily Exposure
  •  The ALARP principle
  •  Examples of low daily dose drug substances
  •  Impurities derived from alkylating agents (mesilate, besilate, tosilate, diisothionate); examples
  •  Nitrosamines – the Valsartan case
  •  Potential mutagenicc residual solvents
  •  Impurities derived from metal catalysts
 
Part III: Elemental Impurities on 03 December

Risk-Based Approach for Elemental Impurities in the Supply Chain
  •  APIs, excipients, packaging materials impacting the purity profile
  •  Evaluation of supply chain processes
  •  Risk analysis as evaluation tool
  •  Audits and monitoring programs as important sources
  •  Testing strategies
Control Strategies for Elemental Impurities in Final Dosage Forms – Case Studies
  •  Utilisation of Data as part of an Integrated EI Risk Assessment Process
  •  Potential Sources of Elemental Impurities in the Finished Product
    • API
    • Equipment
    • Container-closure system
    • Excipients
  •  Conclusions
Workshop:
Conducting a Risk Assessment
