How do you handle OEL derivation for compounds with limited toxicology data?
For compounds with limited data, we employ a comprehensive approach: 1) Read-across analysis from structurally similar compounds, 2) Threshold of Toxicological Concern (TTC) methodologies, 3) Pharmacological activity-based estimation techniques, and 4) Expert professional judgment with conservative uncertainty factors - always providing clear documentation of data gaps and underlying assumptions.
What's your specialized approach for cytotoxic compounds with genotoxic potential?
For genotoxic compounds, we follow a structured tiered approach: 1) Apply TTC-based limits (1.5μg/day) when no threshold can be scientifically identified, 2) Use linear extrapolation from TD50 when relevant data exists, and 3) Consider threshold approaches when robust mechanistic data supports it. All recommendations include comprehensive ALARP (As Low As Reasonably Practicable) implementation guidance.
Can you reconcile differences between EMA HBEL and other OEL frameworks?
Yes, we specialize in creating harmonized approaches that fully meet EMA HBEL requirements for cross-contamination control while also satisfying OSHA and ACGIH expectations for occupational safety, often developing compound-specific 'control bands' that efficiently address both regulatory requirements.
How do you assess risk for novel modalities like cell therapies?
For ATMPs, we modify traditional approaches by: 1) Evaluating replicative capacity rather than classic toxicity endpoints, 2) Considering patient-specific risks (autologous vs allogeneic therapies), and 3) Developing facility controls based on biological containment principles (BSL levels) in addition to traditional chemical exposure paradigms.
What format are your toxicology reports provided in for regulatory submissions?
Our standard deliverables include both comprehensive technical reports (with full methodology and references) and submission-ready modules formatted per CTD requirements, including detailed uncertainty analysis and clear rationale for all derived values suitable for MHRA, FDA, and EMA review processes.
What does the Occupational Toxicology service include?
Our comprehensive service includes precise OEL/ADE derivation, professional OEB classification, facility-wide risk mapping using FMEA methodology, strategic cross-contamination control strategies, customized compound-specific SDS, thorough data gap analysis, and regulatory-ready toxicology summaries.
Which regulatory standards do you follow?
We align with all major regulatory frameworks including EMA HBEL (2014), ICH Q3D (2019), ISPE Risk-MaPP, OSHA 29 CFR 1910.1000, ACGIH TLVs, REACH Regulation, and NIOSH Hazardous Drug Guidelines for comprehensive compliance.
How do you handle novel modalities like ATMPs or ADCs?
We apply specialized, modified risk assessment methodologies specifically tailored to the unique properties and safety considerations of novel modalities like ATMPs, oligonucleotides, and ADCs, ensuring accurate and highly relevant safety evaluations.
What comprehensive deliverables can I expect?
You'll receive detailed OEL/ADE reports, professional OEB classifications, comprehensive FMEA risk matrices, strategic control strategy documents, customized SDS, thorough data gap analyses, and regulatory submission-ready toxicology summaries.
When should I utilize this service?
This service is ideal for new drug development programs, cross-contamination control in shared manufacturing facilities, precise OEL/ADE derivation for high-potency compounds, or ensuring complete compliance during regulatory audits and inspections.
