Part I:
Impurities analysis and qualification 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
  • Inorganic impurities
Control of organic impurities in the European Pharmacopoeia
  • Ph. Eur. analytical techniques used for impurity control
  • Impurity control in general chapters and monographs: General monograph 2034, General chapter 5.10 - control of impurities, General chapter 2.2.46 - chromatographic separation techniques
  • Qualitative and quantitative control: System suitability tests, Methods of quantification, Limit test vs quantitative test
  • Response and correction factors
Practical aspects of method validation for impurity determination
  • Important ICH and FDA guidelines
  • Quantitation 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: enantiomeric puritymand proof of the absolute
  • configuration
In the Workshop the participants will learn which activities are necessary to characterise drug substances taking into account the following aspects:
  • analytical procedures are necessary for the characterisation
  • 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
Stress stability testing during development
  • Elucidation of impurities of the drug substance
  • Identification of possible degradation products
  • Check of the degradation pathways
  • Typical experiments
  • Test parameter
  • Storage conditions
  • Stress tests of multi-use products
  • Impact on excipients and packaging materials

Part II.
EDQM’s implementation strategy of ICH Q3D in the European Pharmacopoeia – an update
  • History of heavy metals tests
  • Implementation strategy of ICH Q3D in Ph. Eur.
  • Modifications of general chapters and general monographs
  • Specific metal tests in individual monographs
ICH Q3D on elemental impurities – requirements and implementation status in the USP general chapters and monographs

Analytical methods to determine elemental impurities
  • Principles and characteristics of the most common spectrometric techniques AAS, ICP-OES, ICP-MS
  • Compound methods (sample preparation plus spectrometric detection and quantification)
  • Special considerations for trace-elemental analysis
  • Application-based approach for choice of methodology
  • Analytical process (method development, validation strategy, routine testing)
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
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.
