Part I: General Strategies for Identification and Control of Impurities on 01 December
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: Selecting Analytical Procedures and Setting Acceptance Criteria of Impurities during Drug Substances Synthesis
- 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
Extractables and Leachables – What is expected from packaging Materials for Drug Products?
- Why should Extractables & Leachables be assessed?
- Regulatory requirements in the EU and US
- Compendial requirements and industry standards
- Safety qualification of Leachables and Extractables
How to avoid or address unexpected Impurities – Cleaning Procedures Pitfalls and particulate Matter Contamination
- 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
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
Safety Qualification of impurities - current Principles and Methods
- General approaches and regulatory framework for impurity qualification by safety threshold derivation
- Generic and substance specific safety thresholds
- Threshold of Toxicological Concern (TTC) - different scenarios
- Derivation of Permitted Daily Exposure (PDE) limits
- Acceptable exposure calculations based on TD50 and their limitations
- Approaches for data poor substances: (Q)SARs and read-across
- Route-to-route considerations for safety thresholds
- Analytical methods used for quantification of N-nitrosylated APIs in drug products
Case Study:
Conducting a Nitrosamine Risk Assessment - Evaluation through Case Studies
Conducting a Nitrosamine Risk Assessment - Evaluation through Case Studies
Several case studies will be presented and a risk assessment for different scenarios is shown 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
