INTRODUCTION
This guidance provides recommendations to applicants on submitting analytical procedures, validation data, and samples to support the documentation of the identity, strength, quality, purity, and potency of drug substances and drug products.
1.绪论
本指南旨在为申请者提供建议，以帮助其提交分析方法，方法验证资料和样品用于支持原料药和制剂的认定，剂量，质量，纯度和效力方面的文件。
This guidance is intended to assist applicants in assembling information, submitting samples, and presenting data to support analytical methodologies. The recommendations apply to drug substances and drug products covered in new drug applications (NDAs), abbreviated new drug applications (ANDAs), biologics license applications (BLAs), product license applications (PLAs), and supplements to these applications.
本指南旨在帮助申请者收集资料，递交样品并资料以支持分析方法。这些建议适用于NDA，ANDA，BLA，PLA及其它们的补充中所涉及的原料药和制剂。
The principles also apply to drug substances and drug products covered in Type II drug master files (DMFs). If a different approach is chosen, the applicant is encouraged to discuss the matter in advance with the center with product jurisdiction to prevent the expenditure of resources on preparing a submission that may later be determined to be unacceptable.
这些原则同样适用于二类DMF所涉及的原料药和制剂。如果使用了其它方法，鼓励申请者事先和FDA药品评审中心的官员进行讨论，以免出现这种情况，那就是花了人力物力所准备起来的递交资料后来发现是不可用的。
The principles of methods validation described in this guidance apply to all types of analytical procedures. However, the specific recommendations in this guidance may not be applicable to certain unique analytical procedures for products such as biological, biotechnological, botanical, or radiopharmaceutical drugs.
本指南中所述的分析方法验证的原则适用于各种类型的分析方法。但是，本指南中特定的建议可能不适用于有些产品所用的特殊分析方法，如生物药，生物技术药，植物药或放射性药物等。
For example, many bioassays are based on animal challenge models, 39
immunogenicity assessments, or other immunoassays that have unique features that should be considered when submitting analytical procedure and methods validation information.
比如说，许多生物分析是建立在动物挑战模式，免疫原性评估或其它有着独特特性的免疫分析基础上的，在递交分析方法和分析方法验证资料时需考虑这些独特的性质。
Furthermore, specific recommendations for biological and immunochemical tests that may be necessary for characterization and quality control of many drug substances and drug products are beyond the scope of this guidance document.
而且，许多原料药和制剂的界定和质量控制所需的生物和免疫化学检测并不在本指南的范围之内。
Although this guidance does not specifically address the submission of analytical procedures and validation data for raw materials, intermediates, excipients, container closure components, and other materials used in the production of drug substances and drug products, validated analytical procedures should be used to analyze these materials.
尽管本指南并不专门叙述原料，中间体，赋形剂，包装材料及原料药和制剂生产中所用的其它物料的分析方法及分析方法验证资料的递交，但是应该应用验证过的分析方法来分析检测这些物质。
For questions on appropriate validation approaches for analytical procedures or submission of information not addressed in this guidance, applicants should consult with the appropriate chemistry review staff at FDA.
对于本指南中未提及的关于分析方法验证和资料提交方面的问题，请向FDA相关的化学评审人员咨询。
This guidance, when finalized, will replace the FDA guidance for industry on Submitting Samples and Analytical Data for Methods Validation (February 1987).
本指南，一旦定稿，将取代FDA于1987年2月份发布的工业指南：分析方法验证所需提交的样品和分析资料。
II. BACKGROUND
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 product, including bioavailability of the drug product (21 CFR 314.50(d)(1) and 314.94(a)(9)(i)).
II. 背景
每个NDA和ANDA都必需包括必要的分析方法以确保原料药和制剂的认定，剂量，质量，纯度和效力，还包括制剂的生物利用度(21 CFR 314.50(d)(1) 和314.94(a)(9)(i))。
Data must be available to establish that the analytical procedures used in testing meet proper standards of accuracy and reliability (21 CFR 211.165(e) and 211.194(a)(2)).
必须要有资料来论证所用的分析方法是符合一定的准确度和可靠性标准的。
Methods validation is the process of demonstrating that analytical procedures are suitable for their intended use. The methods validation process for analytical procedures begins with the planned and systematic collection by the applicant of the validation data to support the analytical procedures.
分析方法验证是论证某一分析方法适用于其用途的过程。分析方法的验证过程是从申请者有计划地系统性收集验证资料以支持分析方法开始的。
