ABSTRACT
ICH-E2E guideline was published on November 18, 2004. In Japan, it has been notified on September 16, 2005 as “Pharmacovigilance Planning”. Then, in parallel with the system development of PMDA is advanced, Ministry of Health, Labour and Welfare revised the notification, it was announced the “Risk Management Plan Guideline” on April 2012. Based on this Guideline, Marketing Authorization Holder creates a whole plan of post-marketing safety measures. This plan is the Japanese RMP (J-RMP). “Risk Management Plan Guideline” are created by the reference to REMS in US and EU-RMP, and modified in consideration of the real situation in Japan. Then, GVP Ordinance and GPSP Ordinance were revised on March 11, 2013. As the result, since October 2014, implementation and creation of the RMP was mandated. At the end of November 2014, 65 RMPs has already been published on Website of PMDA. J-RMP has been positioned as an important system for strengthening of post-marketing safety measures. Published versions of J-RMPs are summarized in compact an overall picture of the post-marketing safety measuresfor respective new drugs. It is also including planned time-line of post-marketing surveillance or post-marketing clinical study. By all stakeholders get a better understanding, it is expected thatthe J-RMP is steadily perform.
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.<br> Development of specific pharmacovigilance plans has remained incomplete because of the limited available experience on which planning can be based.<br> 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.<br> 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.<br> 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.
