Significance and Use4.1 Appl
42、ication of the approach described within this guideapplies risk-based concepts and principles introduced in ICHQ9. As stated in ICH Q9, the level of effort, formality anddocumentation for cleaning should also be commensurate withthe level of risk.4.2 Application of the approach described within this
43、 guideapplies many of the science-based, risk-based, and statisticalconcepts and principles introduced in the FDAs Guidance forIndustry Process Validation: General Principles and Practices(3).4.3 This guide supports, and is consistent with, elementsfrom ICH Q8, ICH Q9, ICH Q10, and ICH Q11.4.4 Key C
44、onceptsThis guide applies the following keyconcepts: (1) quality risk management, (2) science-basedapproach, (3) statistics-based approach, (4) processunderstanding, and (5) continued improvement as described inthe ICH Q series.5. Science-Based, Risk-Based, and Statistics-BasedCleaning Process Devel
45、opment and Validation5.1 Science-based approaches should be applied throughoutthe cleaning process development and validation process.5.2 Quality risk management should be applied throughoutthe cleaning process development and validation process.5.3 Appropriate statistical analysis should be applied
46、throughout the cleaning process development and validationprocess.6. Risk Assessment6.1 Under ICH Q9, risk assessment is broken into threestages: risk identification, risk analysis, and risk evaluation.6.2 Risk can be defined as: risk = f (probability of occur-rence of harm and the severity of that
47、harm).6.3 For the purposes of cleaning, risk can be further definedas a function of the severity of the hazards of process residues,likelihood and level of process residues, and detectability ofprocess residues.6.4 For a reliable assessment of risk, scientific means (forexample, risk management tool
48、s) should be used to identify thehazard presented by a process residue (for example, API,degradation products, intermediates, cleaning agent,bioburden/endotoxin, and so forth), the ability of a cleaningprocess to remove process residues to levels that areacceptable, and the ability to detect and qua
49、ntify the presenceof process residues after cleaning.6.5 Risk IdentificationRisk identification should encom-pass the identification of process residue hazards, equipmentdesign hazards, and procedural hazards.6.5.1 Process Residue Hazard Identification:6.5.1.1 The hazard presented by a potential process residuemay be determined from a toxicological review performed bya qualified toxicologist or qualified pharmacologist. For anAPI, this involves a thorough review of all relevant toxicologi-cal data available for the process residue
