Abstract:
Implementation of the ICH E2E Guideline is based on the Notification dated September 16, 2005 concerning pharmacovigilance planning. The E2E Guideline requires post-marketing safety measures, observational studies, and clinical trials to be performed according to the profile of a particular drug.
Development of specific pharmacovigilance plans has remained incomplete because of the limited available experience on which planning can be based.
Examples of safety measures taken, observational studies, and clinical trials conducted with the anticancer drug TS-1 are explained from the view point of the E2E Guideline.
Important risks identified after the market launch of TS-1 include a significant difference from similar drugs in adverse drug reaction profile, contraindication of concomitant medication with 5-FU-containing drugs due to interactions, and an increase in side effects resulting from renal disorders. Examples of missing information include lack of data on concomitant medication with other anticancer drugs and on the efficacy and safety of post-operative medication. Data on long-term medication were also lacking. How these issues were addressed will be explained.
Plans for post-marketing safety measures, observational studies, and clinical trials cannot be standardized; risks and other specific factors for each particular drug need to be taken into consideration.
