equipment-dependent 设计空间与批量和设备有关设计空间与批量和设备有关Design space determined at the laboratory scale may not be relevant to the process at the commercial scale 实验或小试中取得的设计空间也许与商业实验或小试中取得的设计空间也许与商业生产工艺没有直接的关联生产工艺没有直接的关联 Therefore,design-space verification at the commercial scale becomes essential unless it is demonstrated that the design space is scale-independent.与生产批量有关的设计空间参数应在商业批生产过程中证实与生产批量有关的设计空间参数应在商业批生产过程中证实19Design Space 设计设计空空间间 Design spaImportant NoteFor generic drug/API applications:pDesign space is optionalpQbD can be implemented without a design space because product and process understanding can be established without a formal design space.pImplementation of QbD is strongly encouraged by FDA.For some complex drug substances or drug products,implementation of QbD is considered a required component of the application.20Important NoteFor generic drugControl Strategy控制策略控制策略ICH Q8 defines Control Strategy as:qA planned set of controls,derived from current product and process understanding that ensures process performance and product quality.基于在对产品和工艺的理解基础上制定的控制要点以确保工艺稳定基于在对产品和工艺的理解基础上制定的控制要点以确保工艺稳定和产品质量和产品质量The controls 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
