Witrynaobserved elemental impurities need to be calculated as a total daily amount based on the total daily dose of the drug. Daily amount of elemental impurity = (impurity conc.,(µg)/g)×(mass of drug µg/day) Compare the total daily amount of each elemental impurity with the established Permitted Daily Exposure value (PDE). Witryna• 3 of these impurities were tested and found to be Ames positive (class 2 MI) • As per ICH M7 8.1 option 4 purge factor calculations were carried out on all 10 impurities • Of the 10 impurities 9 were found to be purged to well below the TCC calculated for Osimertinib .
