What is a PDE?

As defined by the EMA’s Guideline on setting health based exposure limits for use in risk identification in the manufacture of different medicinal products in shared facilities, “The PDE represents a substance-specific dose that is unlikely to cause an adverse effect if an individual is exposed at or below this dose every day for a lifetime.”

The PDE is then used in performing your facility’s risk assessment, according to ICH Q9, and used in the maximum allowable carryover (MACO) equation.

What can you expect in Affygility Solutions’ OEL Fastrac PDE reports?

  • Selection of the Point of Departure (PoD)

Don’t get fooled by cheap providers of PDE reports

At Affygility Solutions we see hundreds of different PDE reports each year. Often, when reviewing reports from cheap providers, we see many technical errors and tactics to fool you into thinking that you’re getting quality reports. These technical errors and tactics include:

  • Relying too heavily on animal data for the selection of the point of departure (PoD) and ignoring currently available human clinical data.
  • Performing a limited search strategy or not acquiring important primary sources of information.
  • Ignoring conflicting data.
  • Creating a different monograph for each salt form of the molecule; thus, requiring you to buy separate monographs.
  • Making statements that are not scientifically supported.
  • Relying on data from safety data sheets (SDS) of questionable credibility.
  • Attempting to disguise a PDE report as a comprehensive document by including a report cover, a table of contents, a glossary, redundant filler material, lengthy tables, and CVs in every report. In addition, some providers use large header and footer margins with logos and addresses to make a longer document. These items provide no value and are there to just give the false impression that it’s a lengthy and comprehensive report.
  • Not openly disclosing that their reports expire in 3-5 years; thus, requiring that you purchase a new report upon expiration.

Don’t settle for poor quality and cookie cutter PDE reports

Other toxicology providers sell cookie cutter monographs that are prepared by inexperienced and uncertified teams. In contrast, Affygility Solutions follows a quality-focused process when preparing PDE reports to ensure we deliver comprehensive and compliant monographs. With an increasing number of complex regulations in the pharmaceutical industry, Affygility Solutions’ experienced team of toxicologists routinely reviews new regulatory requirements and guidance to determine regulatory impacts. You can always count on Affygility Solutions to be at the forefront of developing regulatory requirements and trends.

Customers can be certain they’re receiving thorough and complete reports because Affygility Solutions has a 34-step quality assurance process to validate accuracy of all monographs. Affygility Solutions also uses proprietary software tools to alert us when new safety information becomes available that might impact the OEL or PDE calculations.

Affygility Solutions has a long history of providing and supporting toxicology services. This proven track record gives customers peace of mind they’re receiving quality monographs backed with exceptional support.
