Cleaning Validation & Cross Contamination Control for Pharmaceutical Products

Risk-based, toxicology-driven cleaning validation strategies to control cross-contamination and support regulatory inspections.

Bioexcel supports pharmaceutical manufacturers

Bioexcel supports pharmaceutical manufacturers in designing, justifying, and maintaining robust cleaning validation programs aligned with current regulatory expectations.

Our approach to cleaning validation is toxicology-driven and risk-based, ensuring scientifically justified acceptance limits, defensible worst-case selection, and documentation that stands up to regulatory inspections.

We help manufacturers manage cross-contamination risks in shared equipment and facilities while maintaining compliance with EMA guidance, EU GMP, and global regulatory standards.

WHAT WE SUPPORT

  • HBEL / PDE-based cleaning acceptance limits
  • Cross-contamination risk assessment
  • Worst-case product and equipment selection
  • Cleaning validation protocols and reports
  • Inspection and audit readiness

Cleaning Validation Services

HBEL / PDE-Based Acceptance Criteria

Derivation and justification of Health-Based Exposure Limits (HBEL) and Permitted Daily Exposure (PDE) values to establish: – Cleaning acceptance limits -Maximum Allowable Carryover (MACO) Crosscontaminatiocontrol strategies Aligned with EMA guidance and toxicological risk assessment principles.

Worst-Case Product & Equipment Selection

Scientific identification and justification of worst-case products and equipment based on: -Toxicologicalpotency – Solubility and cleanability – Batch size and equipment surface area Prepared to withstand regulatory and inspector scrutiny.

Cleaning Validation Protocols & Reports

Preparation and review of: – Cleaning validation protocols – Sampling strategies (swab and rinse) – Validation reports and conclusions

Documentation is structured to support inspections and audits.

Cross-Contamination Risk Assessment

Evaluation of manufacturing processes and equipment to assess: – Carryover risks – Cleaning effectiveness -Risk control and mitigation measures
Integrated with quality risk management principles.

Alignment & Documentation

Regulatory & Guidance Alignment

Cleaning validation services are aligned with: – EMA guidance on HBEL and cross-contamination – EU GMP requirements – ICH Q9 (Quality Risk Management) – Toxicological risk assessment best practices

Integration with Pharma Compliance Activities

Built for Inspections and Audits

Cleaning validation outputs integrate with: – PDE, OEL & CLP (Pharma) – Nitrosamine Risk Assessment -Extractables & Leachables (Pharma)
This ensures consistent toxicological justification across all pharma compliance activities.
