23、, but sponsors preparing INDs should consider the recommendations in this guidance. For INDs, sufficient information is required at each phase of an investigation to ensure proper identity, quality, purity, strength, and/or potency. The amount of information on analytical procedures and methods suit

24、ability will vary with the phase of the investigation7.For general guidance on analytical procedures and methods validation information to be submitted for phase one studies, sponsors should refer to the FDA guidance for industry on Content and Format of Investigational New Drug Applications (INDs)

25、for Phase 1 Studies of Drugs, Including Well-Characterized, Therapeutic, Biotechnology-Derived Products. General considerations for analytical procedures and methods validation before conduct of phase two and three studies are discussed in the FDA guidances for industry on INDs for Phase 2 and 3 Stu

26、dies of Drugs, Including Specified Therapeutic Biotechnology-Derived Products (February 1999) and IND Meetings for Human Drugs and Biologics, Chemistry, Manufacturing, and Controls Information.本指南并不讨论IND申报中的方法验证，但申请人在准备IND时应考虑本指南中的建议。对于IND，要求一个临床的各阶段都有充分的资料来确保适当的鉴别、质量、纯度、剂量和/或效价。分析方法适用性的资料数量会因临床阶段不同

27、而不同。一般来说，在一期临床提交的分析方法验证资料，需要参考FDA行业指南“药品一期临床研究IND申报资料内容和格式，包括特性明确、治疗用生物技术衍生产品”。在二期和三期临床研究之前的分析方法验证的一般考虑要点在FDA行业指南“药品的二期和三期临床研究IND”和“人用药和生物制品、CMC资料IND会议”中有讨论。This guidance does not address specific method validation recommendations for biological and immunochemical assays for characterization and qua

28、lity control of many drug substances and drug products. For example, some bioassays are based on animal challenge models, and immunogenicity assessments or other immunoassays have unique features that should be considered during development and validation.本指南并不讨论许多原料药和药品的质量控制和生物和免疫化学测定的定性中特定的方法验证建议。

29、例如，有些生物含量是基于动物挑战模式，免疫基因评估或其它免疫测试具有独特的性质，在研发和验证时需要考虑。Analytical methods required during product and process development activities are discussed in FDA guidance for industry on Process Validation: General Principles and Practices.在药品和工艺研发期间所需的分析方法已在FDA行业指南“工艺验证：一般原则和规范”中进行了讨论。In addition, a risk-base

30、d approach on the need for revalidation of existing analytical methods may need to be considered when the manufacturing process changes during the products life cycle. For questions on appropriate validation approaches for analytical procedures or submission of information not addressed in this guid

31、ance, you should consult with the appropriate FDA quality assessment staff.此外，在产品的生命周期中当生产工艺变更时，可能需要采用基于风险的方法考虑是否需要对现有分析方法进行再验证。对于本指南中未讨论的关于分析方法适当的验证方法或资料提交的问题，你应当向适当的FDA质量评估人员咨询。If you choose a different approach than those recommended in this guidance, we encourage you to discuss the matter with t

32、he appropriate FDA quality assessment staff before you submit your application.如果你选择了一个不同于本指南中的方法，我们鼓励你在提交申报资料前与适当的FDA质量评估人员就此事进行讨论。In general, FDAs guidance documents do not establish legally enforceable responsibilities. Instead, guidances describe the Agencys current thinking on a topic and shoul

33、d be viewed only as recommendations, unless specific regulatory or statutory requirements are cited. The use of the word should in Agency guidances means that something is suggested or recommended, but not required.一般来说，FDA的指南文件没有法律强制性。指南只是描述了当局目前对某个专题的考虑，除了其中引用的特定的法规或法律条款要求外，应当仅作为是建议来看待。在官方指南中用词“应”

34、表示建议或推荐某事，但并不是强制要求。II. BACKGROUND 背景Each NDA and ANDA must include the analytical procedures necessary to ensure the identity, strength, quality, purity, and potency of the drug substance and drug product8.Each BLA must include a full description of the manufacturing process, including analytical pr

35、ocedures that demonstrate the manufactured product meets prescribed standards of identity, quality, safety, purity, and potency9.Data must be available to establish that the analytical procedures used in testing meet proper standards of accuracy, sensitivity, specificity, and reproducibility and are

36、 suitable for their intended purpose10.每个NDA和ANDA都必须包括用以确保原料药和制剂鉴别、剂量、质量、纯度和效价的分析方法。每个BLA必须包括生产工艺的全面描述，包括用以证明所生产产品符合所述鉴别、质量、案例、纯度和效价标准的分析方法。必须有数据证明用于测试的分析方法符合适当的准确度、灵敏度、专属性和重复性标准，并适合于其既定用途。Analytical procedures verification or validation data should be submitted in the corresponding sections of the

37、application in the ICH M2 eCTD: Electronic Common Technical Document Specification11.分析方法确认或验证数据应在ICH M2 eCTD“电子通用技术文件规范”申报资料中相应的部分提交。When an analytical procedure is approved/licensed as part of the NDA, ANDA, or BLA, it becomes the FDA-approved analytical procedure for the approved product. This an

38、alytical procedure may originate from FDA recognized sources (e.g., a compendial procedure from the United States Pharmacopeia/National Formulary (USP/NF) or a validated procedure you submitted that was determined to be acceptable by FDA. To apply an analytical method to a different drug product, ap

39、propriate validation or verification studies for compendial procedures with the matrix of the new product should be considered.如果分析方法作为NDA、ANDA或BLA的一部分被批准，则其成为FDA批准产品的批准的分析方法。该分析方法可以是来源于FDA认可的来源（例如，USP/NF药典方法）或一个你所提交的经过验证的方法，而被FDA认为是可以接受的。在不同药品中应用一个分析方法时，要考虑加入新药的基底后对药典方法进行适当的验证或确认研究。III. ANALYTICAL

40、METHODS DEVELOPMENT 分析方法研发An analytical procedure is developed to test a defined characteristic of the drug substance or drug product against established acceptance criteria for that characteristic. Early in the development of a new analytical procedure, the choice of analytical instrumentation and

41、methodology should be selected based on the intended purpose and scope of the analytical method. Parameters that may be evaluated during method development are specificity, linearity, limits of detection (LOD) and limits of quantitation (LOQ), range, accuracy, and precision.研发分析方法是为了测试原料药或药品的指定属性，以确

42、认其是否符合已建立的该属性可接受标准。在新分析方法的研发早期，应根据其应用目的和范围来选择所用的分析仪器和方法。在方法研发中需要进行评估的参数为专属性、线性、检测限（LOD）和定量限（LOQ）、范围、准确度和精密度。During early stages of method development, the robustness of methods should be evaluated because this characteristic can help you decide which method you will submit for approval. Analytical p

43、rocedures in the early stages of development are initially developed based on a combination of mechanistic understanding of the basic methodology and prior experience. Experimental data from early procedures can be used to guide further development. You should submit development data within the meth

44、od validation section if they support the validation of the method.在方法研发早期，应对方法的耐用性进行评估，因为该属性可以帮助你决定提交哪个方法去批准。研发早期的分析方法最早是基于对基础方法学的了解和之前的经验来建立的。早期程序的实验数据可以用于指导进一步的研发。如果这些研发数据支持方法的验证的话，你应该在方法验证部分提交研发数据。To fully understand the effect of changes in method parameters on an analytical procedure, you shou

45、ld adopt a systematic approach for a method robustness study (e.g., a design of experiments with method parameters). You should begin with an initial risk assessment and follow with multivariate experiments. Such approaches allow you to understand factorial parameter effects on method performance. E

46、valuation of a methods performance may include analyses of samples obtained from various stages of the manufacturing process from in-process to the finished product. Knowledge gained during these studies on the sources of method variation can help you assess the method performance.为了全面了解分析方法参数变更的影响，

47、你应该采用一个系统的方法进行方法耐用性研究（例如，设计一个方法参数实验）。开始你应采用风险评估，然后进行多变量实验。这样的方法能让你了解参数因子对方法性能的影响。对方法性能评估可以包括分析来自生产工艺中从中控到成品不同阶段的样品。从这些方法变化来源的研究中获得的知识可以帮助你评估方法的性能。IV. CONTENT OF ANALYTICAL PROCEDURES 分析方法的内容You should describe analytical procedures in sufficient detail to allow a competent analyst to reproduce the n

48、ecessary conditions and obtain results within the proposed acceptance criteria. You should also describe aspects of the analytical procedures that require special attention. An analytical procedure may be referenced from FDA-recognized sources (e.g., USP/NF, Association of Analytical Communities (AO

49、AC) International)12if the referenced analytical procedure is not modified beyond what is allowed in the published method. You should provide in detail procedures from other published sources. The following is a list of essential information you should include for an analytical procedure:你应该将分析方法叙述的

50、足够详细，使得有资质的化验员可以重现必要的条件，获得所拟可接受标准内的结果。你还应该描述分析方法所需的注意事项。分析方法可以引自FDA认可的来源（例如USP/NF，国际分析共同体协会（AOAC），只要被引用的分析方法未修订至超出所公布方法所允许的范围。你应该提供其它出版来源的详细方法。以下是一个分析方法中应该包括的基本信息清单：A. Principle/Scope 原理/范围A description of the basic principles of the analytical test/technology (i.e., separation, detection); target analyte(s) and sample(s) type (e.g., dru
