The manufacture of medicinal products in shared facilities can accidentally result in cross-contamination due to uncontrolled carry-over of active substances or other starting materials. Good Manufacturing Practice (GMP) requires a “toxicological evaluation” to establish threshold values for proper risk identification during cleaning validation.

SAXOCON provides you with everything you need to establish and document Permitted Daily Exposure (PDE) in accordance with regulatory requirements, including:

  • A review of available non-clinical and clinical data
  • Fill in critical data using QSAR and other in-silico models
  • Establishing PDE based on the methods and principles in the EMA guidelines for setting health-based exposure limits for use in risk identification when manufacturing various medicinal products in shared facilities (EMA/CHMP/CVMP/SWP/169430/2012)
  • Identifying major toxic hazards, such as substances with a sensitizing and/or genotoxic potential
  • Control of mutagenic impurities using the methods and principles described in ICH M7
