Level of effort formality and documentation of quality risk management commensurate with level of risk Application of Quality System Concepts ICH Q10 · Pharmaceutical Quality Systems i. Consistency in global pharmaceutical environment iii. Transparency of systems, processes organizational management responsibility iv. · Often formulated with surfactants, chelating Often formulated with surfactants, chelating agents and emulsifiers to enhance effectiveness. · Verification: Similar to validation however data generated apply only to that specific cleaning event. Considerations for Process Capability, Reliability and Consistency · Goal is to operate at process capability that ensures that predefined acceptance limits are consistently met in a reproducible manner · Residue data is used to generate process limits · Acceptance limits should be scientifically justifiable, achievable and risk-based. During process development monitoring generates data for setting acceptance criteria for cleaning validation study ii.Challenges of Aseptic Manufacturing · No terminal sterilization in final container, containers must be filled and sealed in an extremely high quality environment · Parts of final product must be sterilized prior to aseptic assembly · After sterilization any manual or mechanical manipulation of components during assembly poses the risk of contamination Cleaning Validation Considerations for Control of contaminant carry over · Prior to sterile filtration, in-process controls used to ensure cleaning agents, product and process related residues are at a minimum. Investigating Non-conformances · An investigation is initiated if the acceptance criteria are not met for any of the pre-determined specifications required to evaluate the cleaning procedure. After qualification of the cleaning process monitoring provides the data for setting process limits Application of Continuous Process Improvements · Monitoring data provides important information for defining the cleaning process capability.

· 7.0 Documentation The interval between the end of production and the beginning of the cleaning procedure in CV protocols European Commission Annex 15: EU guide to GMP · Normally only cleaning procedures for product contact surfaces of the equipment need to be validated.
Considerations should be given to noncontact parts.
EU Regulatory Considerations for Cleaning Validation EU Guide to GMP · Sensitivity of analytical methods · Worst-case approach case approach · Number of runs: three consecutive applications · Use of surrogates-simulate the physicochemical properties · “Test until clean” not acceptable · The rationale for selecting limits of carryover of product residues, cleaning agents and microbial contamination should be logically based on the materials involved. Flow rate Equipment Design and Compatibility · Generate required equipment specifications based on existing needs e.g.
Application of ICH Guidelines · Provide a structured way to define product critical quality attributes, design space, the cleaning process and the control strategy · Utilizes continuous cleaning process verification/monitoring · Risk assessment highlights focus areas for demonstrating robustness Application of Quality System Concepts ICH Q8 · Pharmaceutical Development Quality by Design i. Real Time release (RTR) testing includes those in-process tests that directly impact the decision for batch release through evaluation of critical quality attributes iii. Control Strategy- controls from product and process understanding that assures process performance and product quality Application of Quality System Concepts ICH Q9 · Quality Risk Management Systematic process for assessment, control, communication and review of risks to quality over product life cycle i. piping and flow designs · Spray ball design and location · Proper equipment design and cleaning ability affects cleaning time, chemical use, disassembly required Selection of Cleaning Agent · Selection should be based on suitability to remove the product residues and for low toxicity the product residues and for low toxicity · Should be acceptable to the process and for use with pharmaceutical products · Acceptable limits for cleaning residues should be established using scientific rationale similar to limits for product residues · Review vendor specification sheets and descriptions, ingredients and percentage of constituents Cleaning Process Development - Design Space · The multidimensional combination and interaction of input Variables (e.g., material attributes) and process parameters that have been demonstrated to provide assurance of quality. sodium hydroxide, sodium per-carbonate, sodium hydrogen carbonate, sodium orthosilicate, sodium metasilicate, Developing Cycle Times for Cleaning Procedure · CIP- Cycle times determined by controlling the Cycle times determined by controlling the primary factors of cleaning efficacy e.g. · On line monitors and sensors for temperature, conductivity p H detergent supply flow rate pressure sensors Establishing Cleaning Cycle · Cycle developed must be validated for specified critical cleaning process parameters e.g. Sampling for positive and negative controls where applicable iv.
The intervals between use and cleaning as well as cleaning and reuse should be validated.
Cleaning intervals and methods should be determined.· Active ingredient · Decomposition products · Excipients · Particulates · Cleaning/Sanitizing agents · Bioburden · Endotoxin Assessment Criteria after Cleaning · Acceptance criteria for selected test markers include the following: 1. · The extent of validation is dependent upon the type of method employed, the capabilities of the method, the scientific and regulatory needs of the resulting data and the anticipated outcome of the testing. Analytical Test Method Specificity · Test Method 1. October 2000 In the pharmaceutical industry, Good Manufacturing Practices (GMPs) require that the cleaning of drug manufacturing equipment be validated.1 Many different validation techniques can demonstrate that the manufacturing equipment is cleaned and essentially free from residual active drug substances and all cleaning agents.Common analytical techniques in the validation process include HPLC, spectrophotometry (UV/Vis), and TOC.Time-frames for the storage of unclean equipment, prior to commencement of cleaning as well as time frames and conditions for the storage of cleaned equipment should be established.
