Bioexcel provides specialized


Bioexcel provides specialized toxicological and exposure assessment services for pharmaceutical manufacturers to support regulatory compliance, patient safety, and worker protection.

Our services focus on the derivation, justification, and documentation of Permitted Daily Exposure (PDE), Occupational Exposure Limits (OEL), and classification and labelling under EU CLP Regulation (EC) No 1272/2008.

All assessments are science-based, risk-driven, and regulator-aligned, suitable for inspections, audits,and regulatory submissions.

WHAT WE SUPPORT

  • Permitted Daily Exposure (PDE) and HBEL derivation.
  • Occupational Exposure Limits (OEL)
  • EU CLP classification and labelling support
  • Toxicological Risk Assessment (TRA)
  • Exposure-based regulatory justifications

Pharma Toxicology & Exposure Services

Permitted Daily Exposure (PDE)

Derivation of PDE values based on toxicological data and regulatory guidance to support: Cleaning validation programs – Cross-contamination control – Shared manufacturing facilities.
PDE assessments are aligned with EMA guidance, ICH Q3C / Q3D, and toxicological risk assessment principles.

Occupational Exposure Limits (OEL)

Development of Occupational Exposure Limits to ensure worker health and safety during pharmaceutical manufacturing, handling, and packaging activities.
OEL assessments support: – EHS programs – Engineering and administrative controls – Safe handling and containment strategies

EU CLP Classification & Labelling

Support for substance and mixture classification and labelling under EU CLP Regulation (EC) No 1272/2008, including: – Hazard identification and classification – Labelling statements and hazard communication – Alignment with Safety Data Sheets (SDS)

Toxicological Risk Assessment (TRA)

Comprehensive Toxicological Risk Assessment to evaluate exposure scenarios, toxicological endpoints, and risk characterization in support of PDE, OEL, and CLP decisions.

Alignment & Documentation

Regulatory & Guidance Alignment

PDE, OEL, and CLP services are aligned with: – EMA and EU regulatory expectations – ICH Q3C and ICH Q3D -EU CLP Regulation (EC) No 1272/2008 – Occupational health and safety frameworks – Risk-based toxicological assessment principles

Integration with Other Pharma Compliance Activities

Built for Inspections and Audits

Outputs from PDE, OEL, and CLP assessments integrate with: – Cleaning Validation (Pharma) – Nitrosamine Risk Assessment – Extractables & Leachables (Pharma)
This ensures consistent toxicological justification across all pharma compliance activities.
