Best Practices for an Effective Cleaning Validation Program

By the end of this course attendees will:

• Understand the importance and underlying principles of validation of cleaning procedures for manufacturing equipment
• Understand the FDA requirements and perspectives on cleaning validation and areas of regulatory concern during inspections and identify gaps in their own programs
• Be able to set up cleaning validation practices, procedures, protocols and reports that meet current FDA, WHO, PIC/S and EU regulations and align with current process validation principles including understanding of critical process parameters, sources and control of variability, process monitoring and control scheme
• Be able to develop and defend your own rigorous but pragmatic cleaning validation approach to avoid costly rejections by regulatory agencies, but also avoid unnecessary activities and overkill

2. Sequence, Duration, Interval, pattern, direction
3. Other Time Concepts- dirty hold time (DHT) and clean hold time (CHT)

Establish Scientifically Sound Contamination Limits

• Convert Qualitative risk to Quantitative risk: Health based contamination levels

1. Maximum Allowable Carryover (MAC) vs. Acceptable Daily Exposure (ADE)
2. Drug Activity-Minimum Therapeutic Dose, Largest Daily Dose
3. Toxic, Allergenic and other bioactive materials

• Purity(adulteration) based limits approach and calculations
• Residue Contamination Risk Matrix
• Critical Quality Attributes-Surface Acceptance Limit (SAL)
• Use of visual criteria for determining if equipment is clean
