35、heFIG. 1 Life Cycle for the Validation of Analytical Method for PAT ApplicationsE2898 143validation of analytical methods for PAT applications. Prerequisites for validation are the identification of the measurementrequirements and development of a method to meet those requirements.4.2 The method ris
36、k assessment also takes into account the stage in the product life cycle at which the measurements are beingmade and how the resulting data will be used. The integration of these considerations in the risk assessment facilitates thedetermination of the level of validation necessary to ensure that th
37、e method is fit for purpose.4.3 Changes may occur during the product life cycle necessitating identification of changes to the measurement requirementsand method update and revalidation. Procedures should be established to evaluate the continued suitability of the process analyticalmethod.4.4 Additi
38、onal informative examples can be found in Practices D3764, D6122, E1655, E1790, E2056, E2617and, E2617andE2656 that address validation of methods and models. Other useful standards include ASME BPE2009, ISO 14971, ISO 15839,and USP Acoustic Emission .5. Significance and Use5.1 Guidance documents for
39、 the validation of off-line, laboratory-based analytical methods frequently have requirements thatcannot be satisfied when applied to at-line, on-line, and in-line analytical methods for PAT applications. This guide providesguidance for the validation of at-line, on-line, or in-line analytical metho
40、ds for PAT applications.Additionally, this guidance shouldbe used in conjunction with Guide E2629 when the PAT measurement is an integral part of a process control system.5.2 The documentation required for validation necessary to demonstrate that the analytical method is fit for purpose for theinten
41、ded application at the stage of the product life cycle may be determined by assessing the risks to quality. The documentationrequirements for validation is determined by risk assessment and will depend on the intended use. For example, a process analyticalmethod used during the development stage for
42、 research purposes may have little or no requirements for documenting validationcompared to a method that is being used during the commercial manufacturing stage of the product life cycle to support qualitydecisions about the product. Similarly, the documentation requirements for validation of a met
43、hod that is being used during themanufacturing stage of the product life cycle to support the quality decision about the product may differ from those listed in ICHQ2(R1). These differences in documentation requirements for validation will depend on the level of criticality of the risk of theapplica
44、tion.6. Procedure6.1 Inputs to Validation:6.1.1 There are a number of inputs to the risk assessment process such as establishing the measurement need, determining theintended purpose, establishing the measurement system, and developing the process analytical method.6.1.2 Defining the Intended Purpos
45、e of the ApplicationThis includes the design intent of the application and the level of therisk associated with the use of the specific application. This is defined well in the ICH Quality Implementation Working GroupPoints to Consider (R2). While the ICH guide discusses levels of as they apply to m
46、odeling, the same principle applies to thevalidation of analytical methods for PAT applications.6.1.2.1 Low-Impact ApplicationsThese are applications that are typically used to support product and process development.This level would include activities of low risk such as gathering information on a
47、process, method feasibility, process andformulation optimization, and other similar activities.6.1.2.2 Medium-Impact ApplicationsIncluded in this category are applications that assure quality, but are not measurement ofproduct quality. Examples of this may include many development measurements that
48、are used to establish design space and otherin process measurements of CQAs that may have another release test for the attribute. Other examples may include measurementsthat can be used for control, but the data is not used specifically for release.6.1.2.3 High Impact ApplicationsThese are applicati
49、ons that fall into the Real Time Release Testing (RTRT) category. Thisis the application that incorporates the measurement to insure product quality by control of the process or is a substitute for aspecification test such as product assay or is replacement for dissolution.6.1.3 Establishing the PAT Measurement SystemMeasurement system qualification is out of scope for this guide and isreferenced here as an input. The extent of the hardware and software qualifications is linked to the purpose of the application. Referto Guide E2500,ASME BP
