美国FDA分析方法验证指南中英文对照（三）

VI. CONTENT AND FORMAT OF ANALYTICAL PROCEDURES FOR NDAs, 230ANDAs, BLAs, AND PLAs

Any analytical procedure submitted in an NDA, ANDA, BLA, or PLA should be described in sufficient detail to allow a competent analyst to reproduce the necessary conditions and obtain results comparable to the applicant=s. Aspects of the analytical procedure that require special attention should be described.

VI．　NDA，ANDA，BLA和PLA中分析方法的内容和格式

NDA，ANDA，BLA和PLA中所提交的任一分析方法都应当要有详细的描述，以使合格的分析人员能重现出所需的实验条件并获得和申请者相当的实验结果。应当要叙述分析方法中需要特殊注意的地方。

If the analytical procedure used is in the current revision of the USP/NF or other FDA recognized standard references (e.g., AOAC International Book Of Methods) and the referenced analytical procedure is not modified, a statement indicating the analytical procedure and reference may be provided rather than a description of the method (21 CFR 211.194).

如果所用的分析方法是USP/NF或其它FDA认可参考文献（如，<<AOAC国际方法汇编>>）中且所参考的分析方法未经过修改的话，则需提供该分析方法的参引，而不用提供该分析方法的描述（21 CFR 211.194）。

A description of analytical procedures from any other published sources should be provided, because the referenced sources may not be readily accessible to the reviewer.

对于从其它公开发表的文献上获得的分析方法，应当要对其进行叙述，因为评审官可能并不能很方便的获得这些文献。



A. Principle

A statement of the principle of the analytical procedure should be included. For example, separation is based on isocratic reversed phase HPLC with detection by UV.

A．基本方法

HPLC进行分离的，检测器为UV检测器。


B. Sampling

 　The number of samples (e.g., vials, tablets) selected, how they are used (i.e., as individual or composite samples), and the number of replicate analyses per sample should be described.

B．取样

需要叙述的有：所选样品的数目（比如，瓶，片等），它们是如何使用的（也就是，单独的或是混合样品），每个样品分析的重复次数。


C. Equipment and Equipment Parameters

A listing of all equipment (e.g., instrument type, detector, column type, dimensions) should be included, as well as a list of equipment parameters (e.g., flow rate, temperatures, run time, wavelength settings). A drawing representing the experimental configuration (e.g., illustrating positions for a spray pattern analytical procedure) should be provided, when appropriate.

C．仪器和仪器参数

需要叙述的有：仪器列表（比如，仪器类型，检测器，柱子类型，尺寸等）和仪器参数（比如，流速，温度，运行时间和设定波长等）。如果必要的话，还要提供实验结构示意图（比如，阐述喷洒式分析方法的位置）。


D. Reagents

A list of reagents and their grades (e.g., USP/NF, American Chemical Society (ACS) Analytical Reagent) should be included. If in-house or modified commercial reagents are used, directions for their preparation should be included. Unstable or potentially hazardous reagents should be identified, and storage conditions, directions for safe use, and usable shelf life for these reagents should be specified.

D．试剂

需要叙述的有：试剂列表及其相应的规格（比如：USP/NF，美国化学社（ACS）分析试剂）。如果使用的是自制试剂或更改过的商业试剂，则应当要有其制备方法。对于不稳定的或有潜在危险的试剂，应标明其储存条件，安全使用说明和使用周期。


E. System Suitability Testing

System suitability test parameters and acceptance criteria are based on the concept that the equipment, electronics, analytical operations, and samples to be analyzed constitute an integrated system. System suitability testing ensures that the system is working properly at the time of analysis. Appropriate system suitability criteria should be defined and included in the analytical procedure.

E．系统适应性实验

系统适应性实验参数和合格标准是建立基础是：仪器，电子元件，分析操作和待测样品是个不可分割的整体。系统适应性实验确保系统在样品分析的时候能很好地运行。在分析方法中应当要包括适当的系统适应性合格标准。

All chromatographic analytical procedures should include system suitability testing and criteria. Parameters typically used in system suitability evaluations are defined and discussed in the CDER reviewer guidance on Validation of Chromatographic Methods (November 1994).

所有的色谱分析方法都应当要有系统适应性实验及相应的合格标准。CDER评审官指南<<色谱分析方法的验证>>（1994年11月）对用于评估系统适应性的典型参数进行了定义和讨论。

System suitability testing is recommended as a component of any analytical procedure, not just those that involve chromatographic techniques. Regardless of the type of analytical procedure, testing should be used to confirm that the system will function correctly independent of the environmental conditions. For example, titration analytical procedures should always include the evaluation of a blank (commonly referred to as a blank titration).

建议系统适应性实验应成为所有分析方法的一部分，而不仅仅是色谱分析方法。无论是哪类分析方法，都要采用实验来证实该系统能不受环境条件的影响而正确地运行。比如说，滴定法一般来说需要进行空白实验。


F. Preparation of Standards

Procedures for the preparation of all standard solutions (e.g., stock, working standard solutions, internal standards) should be included.

F．标准品的制备

要有所有标准品溶液（比如，储备液，工作对照品溶液，内部对照品溶液）的配制方法。


G. Preparation of Samples

Sample preparation for individual tests should be clearly described. Specific details should be provided for unusual sample preparations (e.g., solid-phase extraction, derivatization).

G.操作过程

应当要按操作步骤对操作过程进行逐步叙述。叙述应当要适当包括如下信息：平衡时间，样品进样顺序和系统适应性或启动参数。需标明不常见的危险。


I. Calculations

Representative calculations, with a tabulation defining all symbols and numerical factors, and specific instructions for the calculation of degradation products and impurities should be included. Any mathematical transformations or formulas used in data analysis should be described in detail. These may include logarithmic transformations used to obtain a linear relationship from exponential data, or the use of multiple order regression analyses.

I．计算

应当要提供代表性计算公式，并要列表说明所有符号和数字系数，及计算降解产物和杂质的特殊使用说明。所有用于数据分析的数学转换或公式应详细描述。这些包括对数转换以获得指数数据的线性关系，或多元回归分析的使用。


J. Reporting of Results

J.结果报告


1. General

The format used to report results (e.g., percent label claim, weight/weight, weight/volume, parts per million (ppm)) including the specific number of significant figures to be reported should be provided.

1．通则

应该规定关键计算步骤中的数字单位（例如，‘标签’标示量的百分比，W/W，W/L，ppm等）


2. Impurities Analytical Procedures

The name and location/identifier (e.g., retention time (RT), relative retention time (RRT)) of impurities and the type of impurity (e.g., process, degradant, excipient degradant) should be included in the analytical procedures for impurities in the drug substance and drug product. The detection limit (DL) or quantitation limit (QL) should be stated, as appropriate. The DL or QL can be set using the drug substance's detection response.

2．杂质分析规程
在有关原料药和产品的杂质检测规程中，应当包括杂质的名称和检测位/标志（例如，保留时间RT，相对保留时间RRT），以及杂质的种类（比如工艺降解产物，赋形剂降解产物），如有可能，还应当指明检测限DL或定量限QL。也可以在原料药检测中设置DL和QL。

Reporting of organic impurities should cover (1) specified identified impurities by name, (2) specified unidentified impurities by location/identifier, (3) any unspecified impurities, and (4) total impurities. The total organic impurities for the drug product or drug substance is the sum of all impurities equal to or greater than their individual QL.

See recommendations regarding appropriate QLs in FDA impurities guidances (see references). Inorganic impurities and residual solvents should also be addressed.

有机杂质的报告中，应当包括：1、有记载的已经过确认的杂质的名称；2、有记载但未经过确认杂质的（检测）位/标志；3、所有的没有记载的杂质，以及；4、总杂质。总有机杂质是指所有达到或超过其自身定量限度的杂质的总量。在这里可以参考FDA杂质指南文章中有关判定定量限度的内容（看后面的参考）。无机杂质和溶剂的残留，也应该被提到。

For the drug product, drug substance process impurities may be excluded from reporting if an acceptable rationale is provided in the sections on analytical procedures and controls. Drug product impurities from the drug product manufacturing process, packaging, and labeling should be addressed.

对于产品以及原料药的工艺杂质也可以不包括在报告中，除非分析规程和控制环节中描叙了一个可以被接受的原则，那么，在产品制造和包装过程中（包括贴签）产生的杂质就要被提到。

The above reporting information may not be strictly applicable to all products (e.g., biological, biotechnological, botanical, radiopharmaceutical drugs), but any significant process and product-related impurities should be determined and reported.

并不是所有产品（比如，生物制剂、生物工艺制剂、植物制剂、放射制剂）的报告都必须严格按照以上谈到的内容来写，但是所有关键的工序以及产品相关的杂质都要有检测和报告。
