Why USP<1207>Needs Revision
为何要修订USP<1207>
Evolving Risks and Modern Manufacturing Demands不断演变的风险与现代化生产需求
- Outpaced by Global Standards:<1207>lags behind EU Annex 1 and industry best practices in lifecycle integration and process control. 落后于全球标准：<1207>在生命周期整合和过程控制方面落后于欧盟附录1及行业最佳实践。
- Gaps in Guidance:Lacks clarity on MALL for polymers,surrogate testing,and sub-ambient CCl assessments."指南中的空白：缺乏关于在聚合物材料的最大允许泄漏限值(MALL)、替代物测试以及低温容器密封完整性(CCI)评估的清晰指导。
- Limited Practical Utility:Fails to support complex therapies or biologics that block defect pathways during testing.实用价值有限：无法为复杂疗法或生物制剂提供支持，这些制剂在测试过程中会“自己堵漏”。
