The importance of the cynomolgus macaque’s origin in drug safety assessment

Cynomolgus macaques are the most commonly used non-human primate species for drug safety assessment. However, recent supply shortages  have brought increased attention to the genetic differences between cynomolgus macaques of varying geographic origins. It is important to examine the relevance of geographic origin for cynomolgus macaques used in regulatory toxicology studies.

Key learnings from ECHA's review of the EOGRTS (OECD Test Guideline 443)

The extended one-generation reproductive toxicity study (EOGRTS) per OECD Test Guideline 443 is a crucial test for evaluating potential reproductive and developmental effects of chemicals. Recently, the European Chemicals Agency (ECHA) conducted an extensive review of EOGRTS  studies to assess the effectiveness of this test guideline and provide recommendations for improvement. This blog post summarizes  key learnings from ECHA's review and the impacts on current and future EOGRTS study design.
