Japan Revises Regulations on Post-Marketing Surveillance

Introduction to Regulatory Changes 

According to the news (厚労省、全例調査の除外規定を事務連絡  Q&Aを一部改正 | 日刊薬業 – 医薬品産業の総合情報サイト (jiho.jp)) released by NIKKAN YAKUGYO on 07/19/2024, significant changes have been made regarding the requirement for All Case Surveillance (ACS) as a condition for drug approval, and ACS will no longer be uniformly required. Instead, exceptions are now permitted based on specific criteria. This revision is part of the ongoing efforts to address drug lag and streamline regulatory processes. In the above context, the amendments of the Q&A on the regulation of ACS are available. 

 

Key Amendments to the Q&A 

The revised guidelines clarify that insufficient Japanese patient data in clinical trials should not be the sole reason for requiring ACS as part of the approval conditions. Examples where ACS may be reconsidered include: 

  • Cases where, despite limited Japanese trial data, sufficient safety information is available from international trials, and there are no significant ethnic differences in safety concerns. 
  • Cases where similar drugs with the same mechanism of action have established safety records, and consistent safety data is available. 

 

Background and Implications  

This policy shift is rooted in the findings of the April 24 report from the “Study Group on Pharmaceutical Regulations to Strengthen Drug Development and Ensure Stable Supply.” The MHLW aims to improve the efficiency of the drug approval process while ensuring safety and effectiveness. Reducing unnecessary ACS requirements alleviates the regulatory burden on pharmaceutical companies, potentially accelerating the introduction of new drugs to the Japanese market. 

 

Conclusion  

These changes mark a significant step towards optimizing Japan’s pharmaceutical regulatory framework. Pharmaceutical companies in the Japanese market should carefully review these updates to understand the new regulatory expectations and align their post-marketing surveillance strategies accordingly.
