Choose properly adjustment factors for ADE & PDE calculation

The EMA guideline calls for the creation of Health Based Exposure Limits (HBEL) to be used in analyzing the risks of remaining active substance infection through medicinal products. Basis and formation of Permitted Daily Exposure (PDE), also known as ADE PDE Calculation has thus become an essential part of the cleaning validation plan for pharmaceutical manufacturing facilities or Manufacturer Organizations (CMOs), in required to conform with various Regulatory or cGMP requirements.

The use of ADE PDE Calculation produced from a scientific and toxicological risk assessment of clinical and non-clinical data can be used to control or restrict the potential risk of pass. The ADE Calculation involves steps such as identifying risks through a structured and strategized literature search, identification of critical effects, establishment of (No-observed-effect level, no-observed-adverse-effect level) (NOEL/NOAEL) for critical effects, and application of adjustment factors such as bioavailability correction factors for a route to route analysis as per the European Medicines Agency (EMA), 2014, ICH Q3C, ISPE, and VICH GL18. Cleaning validation in manufacturing plants uses PDE/ADE measurements to establish the maximum acceptable carryover (MACO values). Most harmful substances, such as cytotoxic medicines, hormones, and steroids, have PDE/ADE values that aid in the selection of dedicated and separate equipment and facilities.

Cross contamination is a problem when different medicinal products are manufactured in shared facilities. As a result, the presence of such chemicals should be managed in keeping with the risk posed, which is related to safe levels for all populations. Even after a lifetime of exposure, the PDE value represents a dose that is unlikely to produce damage to one individual. The phrase ‘Acceptable Daily Exposure (ADE)’ is similar with this. Non-toxicologists (such as GMP inspectors) should be able to interpret and verify the calculated PDE values based on the expert logic.

Our Experience

Freyr toxicologists have developed and delivered over 1500 high-quality ADE PDE Calculation reports/monographs in line with EMA, ISPE, ASTM, and other country-specific guidelines over the years. PDE/ADE reports for oral, parenteral, inhalation, topical, and some of the more uncommon routes, such as ophthalmic and otic, have been created by Freyr toxicologists and have been subjected to critical verification during GMP inspections and critical reviews by our clients’ in-house toxicologists.
