3.2.1 Process Performance and Product Quality Monitoring System
Pharmaceutical companies should plan and execute a system for the monitoring of process performance and product quality to ensure a state of control is maintained. An effective monitoring system provides assurance of the continued capability of processes and controls to produce a product of desired quality and to identify areas for continual improvement. The process performance and product quality monitoring system should:
(a) Use quality risk management to establish the
control strategy. This can include parameters and attributes related to drug substance and drug product materials and components, facility and equipment operating conditions, in-process controls, finished product specifications, and the associated method sand frequency of monitoring and control. The control strategy should facilitate timely feedback / feedforward and appropriate corrective action and preventive action;
(b) Provide the tools for measurement and analysis
of parameters and attributes identified in the control strategy (e.g., data management and statistical tools);
(c) Analyse parameters and attributes identified in
the control strategy to verify continued operation within a state of control;
(d) Identify sources of variation affecting process
performance and product quality for potential continual improvement activities to reduce or control variation;
(e) Include feedback on product quality from both
internal and external sources, e.g., complaints, product rejections, non-conformances, recalls, deviations, audits and regulatory inspections and findings;
3.2.1工艺性能和产品质量监控系统 制药企业应规划和执行工艺性能和产品质量监控体系以确保控制状态得到了维持。有效的监控体系保证了持续性工艺性能和控制,以生产出需要的质量的产品和确定持续改进的范畴。工艺性能和产品质量监控体系应: (a)应用质量风险管理以建立控制策略,可以包
括原料药及药用物质和组份相关参数与属性,设施和设备运行条件,过程控制,成品质量标准,及监控和控制的相关方法与频率。控制策略应促进及时反馈/前馈及适宜的纠正措施和预防措施。
(b)提供控制策略中所确定参数与属性的衡量与分析工具,比如数据管理和统计工具 (c)分析控制策略中所确定参数与属性以证实后续操作受控
(d)确定影响工艺性能和产品质量的变量,持续改进活动会减少或控制这些变量
(e)包括产品质量的内外部反馈,如投诉,产品否决,不合格,召回,偏差,审计和官方检查与发现

(f) Provide knowledge to enhance process
understanding, enrich the design space (where established), and enable innovative approaches to process validation.
(f)提供知识以增强工艺理解,丰富设计空间(如建立的话),并实现工艺验证的创新方法

3.2.3变更管理体系
Innovation, continual improvement, the 革新,持续改进,工艺性能和产品质量监控及outputs of process performance and product quality monitoring and CAPA drive change. In order to evaluate, approve and implement these changes properly, a company should have an effective change management system. There is generally a difference in formality of change management processes prior to the initial regulatory submission and after submission, where changes to the regulatory filing might be required under regional requirements.
The change management system ensures continual improvement is undertaken in a timely and effective manner. It should provide a high degree of assurance there are no unintended consequences of the change.
The change management system should include the following, as appropriate for the stage of the lifecycle:
(a) Quality risk management should be
utilised to evaluate proposed changes. The level of effort and formality of the evaluation should be commensurate with the level of risk;
(b) Proposed changes should be
evaluated relative to the marketing authorisation, including design space, where established, and/or current product and process understanding. There should be an assessment to determine whether a change to the regulatory filing is required under regional requirements. As stated in ICH Q8, working within the design space is not
CAPA都会趋势变更。为了适宜地评估,批准和执行这些变更,公司应具有有效的变更管理体系。一般来说,注册文件递交前后的变更管理流程是有些区别的,需遵从区域法规的要求进行注册文件的变更。 变更管理体系确保持续改进得到了及时有效的执行,并高度保证变更不会引发不期望的后果。 变更管理体系应在生命周期的各个阶段包括如下: (a)运用质量风险管理评估计划的变更。评
估的努力程序与正式程序应与风险水平相当。
(b)应根据相关的上市许可,设计空间(如
建立的话),和/或现行产品和工艺理解对计划的变更进行评估。需通过评估确定是否需要根据区域要求进行注册文件的变更。如ICH Q8所述,设计空间内的变动不被认为是变更(从注册文件的角度来看)。但是从制药质量体系的立场来看,所有的变更均需根据公司的变更管理体系进行评估。
