Regulatory Analytical Procedure A regulatory analytical procedure is the analytical procedure used to evaluate a defined characteristic of the drug substance
27、 or drug product. The analytical procedures in the U.S. Pharmacopeia/National Formulary (USP/NF)are those legally recognized under section 501(b) of the Food, Drug, and Cosmetic Act (the Act) as the regulatory analytical procedures for compendial items. For purposes of determining compliance with th
28、e Act, the regulatory analytical procedure is used.III分析方法的类型A. 法定分析方法法定分析方法是被用来评估原料药或制剂的特定性质的。USP/NF中的分析方法是法定的用于药典项目检测的分析方法。为了确认符合法规,需使用法定分析方法。B.

Types of Standards A reference standard (i.e., primary standard) may be obtained from the USP/NF or other official sources (e.g., CBER, 21 CFR 610.20). If there are questions on whether a source of a standard would be considered by FDA to be an offic
35、ialsource, applicants should contact the appropriate chemistry review staff. When there is no official source, a reference standardshould be of the highest possible purity and be fully characterized.IV 标准品A标准品的类型可以从USP/NF处或其它官方(比如说,CBER,21CFR 610.20)获得标准品 (也就是一级对照品)。如果不能确定一标准品的来源是否会被FDA认为是官方来源,申请者应当
36、要向适当的化学评审人员咨询。如果没有官方来源,则被用来作标准品的物质应当要有尽可能高的纯度,并得到充分界定。4/ working standard (i.e., in-house or secondary standard) is a standard that is qualified against and used instead of the reference standard.工作对照品 (也就是内部标准品或二级标准品)是根据一级对照品标定的,并用来代替一级对照品的。B.

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 evalua
71、tion 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.

96、的安慰剂还是分解了的安慰剂都不会影响活性成分的定量分析。ICHQ2A和ICHQ2B几乎对所有的验证参数都进行了论述。下面论述的是那些还需要更详细地进行论述的方面。a. RobustnessRobustness, a measure of the analytical procedures capability to remain unaffected by small but deliberate variations, is described in ICH Q2A and Q2B. Such testing should be performed during development of
97、 the analytical procedure and the data discussed and/or submitted. In cases where an effect is observed, representative instrument output (e.g., chromatograms) should be submitted.a.耐用性ICHQ2A和ICHQ2B对耐用性是有论述的,它衡量的是分析方法在细微的变化下不受影响的能力。该实验应当是在分析方法开发过程中进行的,对实验结果进行讨论和/或递交。如果观察到有影响,需提供代表性仪器输出(如色谱图)。b. Stre
98、ss StudiesDegradation information obtained from stress studies (e.g., products of acid and base hydrolysis, thermal degradation, photolysis, oxidation) for the drug substance and forthe active ingredient in the drug product should be provided to demonstrate the sp10/ of the assay and analytical proc
99、edures for impurities. The stress studies should demonstrate that impurities and degradants from the active ingredient and drug product excipients do not interfere with the quantitation of the active ingredient. Stress studies are described in various FDA guidances relating to the stability of drug
100、products (see references). The design of the stress studies and the results should be submitted to the stability section of the application. Representative instrument output (e.g., chromatograms) and/or other appropriate data (e.g., degradation information obtained from stress studies) should be sub
101、mitted in the sections on analytical procedures and controls.b.强降解实验FDA很多关于药品稳定性的指导原则都对强降解实验进行了论述。在申请的稳定性一章中应当要提供的资料有:强降解实验设计和实验结果。而代表性仪器输出(如:色谱图)和/或其它资料(强降解实验中所得的降解信息)应当要提供在分析方法和控制一章中。c. Instrument Output/Raw Datai. Organic ImpuritiesRepresentative data should be submitted to support an assessment
102、of the organic impurities. Representative data for residual solvents are generally not needed. Instrument output and the raw numerical values (e.g., peak area) with appropriate identificationand labeling (e.g., RT for chromatographic peaks, chemical shift (d) and coupling constant (J) for NMR) shoul
103、d be provided. The impurity profile should be assessed at the quantitation limit and the instrument output provided. Additional information should be provided to confirm that the impurity profile is adequately characterized. For example, a representative chromatogram using detection at a low wavelen
104、gth, such as 205 nm, and double the proposed total run time could be submitted to support the specificity of the analytical procedure.c.仪器输出/原始资料i. 有机杂质应当要提供代表性资料以支持有机杂质的评估。一般来说,是不需要残留溶剂的代表性资料的。仪器输出和原始数值(比如,峰面积)及合适的标记和标注(比如,色谱峰的保留时间,核磁共振的化学位移和耦合常数)都应当要提供。根据所提供的定量限和仪器输出对杂质情况进行评估。还应当要提供其它资料以确认杂质情况得到了充
105、分地界定。比如说,比如说,代表性图谱选用的检测波长是205nm,则可以将拟定的运行时间延长至两倍以支持分析方法的专属性。For quantitation purposes, the response factor of the drug substance may be used for impurities without a reference standard. In cases where the response factors are not close, this practice may still be acceptable, provided a correction fa
106、ctor is applied or the impurities are, in fact, being overestimated. Acceptance criteria andanalytical procedures used to estimate identified or unidentified impurities often are based on analytical assumptions (e.g., equivalent detector response). Assumptions should be discussed and justified.在定量分析
107、时,原料药的响应因子可用于没有相应对照品的杂质。如果响应因子不接近的话,只要应用了较正因子或或者杂质实际上是被高估的话,这样做也是可行的。用于评估指定杂质或未指定杂质的合格标准和分析方法经常都是基于分析假设的(比如,相当的检测器响应)。应当要对这些假设进行讨论和合理性说明。ii. Drug SubstanceData should be submitted showing the separation and detection of impurities using spiked or stress samples. Complete impurity profiles as graphic
108、 output (e.g., chromatograms) and raw data (e.g, integrated peak areas) of representative batches should be submitted in the sections on analytical procedures and controls for the drug substance. For ANDAs and related submissions, appropriate information for the batches used in the biobatch or submi
109、ssion batch should be provided. All responses (e.g., peaks) should be labeled. The analytical procedure used should be capable of differentiating changes, if any, between past and present batches. The quantitation limit and the type of organic impurity (e.g., degradant, process impurity) should be s

112、s and controls of the drug product. For ANDAs and related submissions, appropriate information for the biobatch or submission batch should be provided. References to the raw data (e.g., chromatograms) should be included in the stability section ofthe application.11/ a minimum, the submission should
113、include instrument output and raw data for release testing and at the latest available time point for the same batch. All responses (e.g., peaks) should be labeled and identified. In addition, the analytical procedure number, batch number of the drug product, manufacturing date, date of analysis, so
114、urce and batch number of drug substance, manufacturing site, and container/closure information should be provided. The analytical procedures used should be capable of differentiating changes, if any, between past and present batches. The quantitation limit and the type (e.g., degradant, leachables f
115、rom packaging) should be reported. Multiple methodologies can be used.至少,递交材料中应当要包括放行检测(Release testing)的仪器输出和原始资料. 需标注所有的响应信号(如色谱峰)。此外,还要提供,分析方法编号,制剂的批号,生产日期,分析日期,原料药的来源和批号,生产地点及容器/密闭系统信息。如在过往批次和现批次之间存在差异的话,所用的分析方法应当要有能力区分出来。应当要报告检测限和类型(如,降解物,包装时的漏出物)。3. Recommended Validation Characteristics for T
116、ypes of TestsTable 1 is a summary of the validation characteristics that should be addressed during validation of different types of analytical procedures. The same methodology can be used for several purposes. The validation information should support the intended purpose of the test. For example,
117、if Raman spectroscopy is the methodology selected to quantitate polymorphic forms as impurities, or chiral HPLC for enantiomeric impurities, the recommended validation characteristics in Table 1 under quantitative testing forimpurities would apply. However, if Raman spectroscopy or chiral HPLC are u
118、sed for the purpose of identification or as specific tests, the recommended validation characteristics listed for those types of tests would apply.3.各类检测的推荐验证项目表1概述了在不同分析方法的验证过程中所需要的验证项目。同一分析方法可用于多个用途。验证资料需要能支持该分析方法的拟定用途。比如说,如果拉曼光谱用于定量分析多晶型杂质,或手性HPLC用于分析异构体杂质,则要应用表1中杂质定量分析中所推荐的验证项目。然而,如果拉曼光谱或手性HPLC被
119、用于鉴定或特征实验的话,则要应用表1中所推荐的这些类型的验证项目。表1:不同类型检测的推荐验证项目 检验项目验证内容 鉴别杂质测定含量分析及溶出度(仅用于检测)含量/效价特殊分析定量限度准确度+-+4精密度重复性+-+4精密度中间精密度+-+14专属性+2+5+4检测限-3+-定量限-+-线性-+-+-范围-+-+-耐用性-+-3+4NOTE:- Signifies that this characteristic is not normally evaluated.+ Signifies that this characteristic is normally evaluated.1 In
120、cases where reproducibility has been performed, intermediate precision is not needed.2 Lack of specificity for an analytical procedure may be compensated for by the addition of a second analytical procedure.3 May be needed in some cases.4 May not be needed in some cases.5 Lack of specificity for an
121、assay for release may be compensated for by impurities testing.注:12/ analytical procedures may include tests such as IR, differential scanning calorimetry (DSC), X-ray diffraction (XRD), UV, and HPLC retention time. A specific identification test should be included for the active ingredient whenever
122、 possible.In cases where a nonspecific identification analytical procedure is proposed for the active ingredient, two independent analytical procedures are generally sufficient, if justified. For other identification tests (e.g., a chiral HPLC retention time as confirmation for the presence of an en
123、antiomer, chloride test for a counterion) a single test is acceptable. This concept of the number of identification tests is applicable to both the drug substance and drug product.a. 鉴别定性分析方法有:红外(IR),差示热分析(DSC),X-射线衍射(XRD)和HPLC保留时间。对于原料药,尽可能要有专属性强的鉴别实验,如果用的是专属性不强的定性分析方法,则通常来说运用两个独立的分析方法应当是足够的。对于其它的一
124、些定性分析方法(如,手性HPLC的保留时间用于确认是否存在异构体,平衡离子的氯化物实验),就一个检测也是可可行的。定性实验数目的概念既适用于原料药,也适用于制剂。b. ImpuritiesThe validation characteristics under quantitative testing for impurities, as described in Table 1, apply, regardless of which methodology is used to quantitate impurities. If the same analytical procedure i
125、s proposed as a limit test, validation characteristics under limit testing for impurities will apply.b. 杂质表1中杂质定量分析 项下所说的相应验证项目。如果同样的方法还用做定性检测的分析方法的话,则要对表1中杂质定性分析 项下的验证项目进行验证。c. AssayAssay includes the content of the active ingredient, preservative (if used), and measurement of content in dissolutio
126、n and content uniformity samples.c. 含量含量分析包括活性成分的含量,所用到的防腐剂的含量,及溶出度和含量均匀度检测样品的含量测定。d. Specific TestsSpecific tests to control the drug substance, excipient, or drug product can include tests such as particle size analysis, droplet distribution, spray pattern, dissolution (excludes measurement), opti
127、cal rotation, and methodologies such as DSC, XRD, and Raman spectroscopy. The validation characteristics may differ for the various analytical procedures. For example, accuracy, repeatability, intermediate precision and robustness should be evaluated for molecular size distribution gel permeation ch
128、romatography(GPC).d.特定实验用于原料药,赋形剂或制剂控制的特定检测包括粒径分析,雾化状态,溶出度,旋光度和比如DSC,XRD及拉曼光谱等方法。不同的分析方法所需的验证项目是不尽相同的。比如说,对于凝胶渗透色谱(GPC),需要考察其准确度,重复性,中间精密度和耐用性。B. Compendial Analytical ProceduresThe suitability of a compendial analytical procedure must be verified under actual conditions of use (21 CFR 211.194(a)(2)
129、. Information to demonstrate that USP/NF analytical procedures are suitable for the drug product or drug substance should be includedin the submission. Information on the specificity, intermediate precision, and stability of the sample solution should be included. Compendial assay analytical procedu
130、res may not be stability-indicating, and this should be considered when developing the specification (see section III.C). For compendial items, additional analytical procedures, such as impurities or osmolality, may be requested to support the quality of the drug product or drug substance. These add
131、itional analytical procedures should be validated (see section VII.A).B药典分析方法(21CFR 211.194(a)(2)。13/ STATISTICAL ANALYSISA. GeneralMethods validation includes an assessment of the adequacy of the analytical procedure. Statistical analysis (e.g., linear regression analysis, relative standard deviati
132、on) of methods validation data is often used to demonstrate the validity of the method. The statistical procedures for the analysis of the validation data should be determined prior to the start of any validation study. The procedure followed, including the amount of data to collect and the criteria
133、 used in determining the acceptability of the analytical procedure, should be specified.The raw methods validation data and statistical procedures used to analyze the raw data should be provided and discussed in the sections on analytical procedures and controls. All statistical procedures used in t
134、he analysis of the data should be based on sound principles and be suitable for evaluating the dataset.VIII. 统计分析A基本原则(比如:线性回归分析,相对标准偏差)以说明方法的正确性。在开始分析方法验证之前,应当就要确定用于验证资料分析的统计方法。还应当要规定所要遵循的程序,包括所需采集的数据量和确定分析方法合适性的合格标准。应当要在分析方法和控制章节中提供和讨论分析方法验证原始资料和所用的统计方法。所有用于数据分析的统计程序都应当是科学的,并适用于评估该数据群的。B. Comparat
135、ive StudiesComparative studies are performed to evaluate intermediate precision (e.g., different equipment, analysts, days). Comparative studies are also used to evaluate between laboratory variability (i.e., reproducibility) when an analytical procedure is used in more than one laboratory or to com
136、pare and evaluate the precision and accuracy of two analytical procedures (e.g., regulatory analytical procedure and an alternative analytical procedure). When comparative studies are performed, homogeneous samples from thesame batch should be used, if feasible. Comparative results should be statist
137、ically analyzed and discussed and any bias explained.B:对比研究开展对比研究以评估中间精密度(如,不同设备,不同分析员,不同天等)。当一分析方法会在多个实验室应用时,或要比较和评估两个分析方法(比如,法定分析方法和替代分析方法)的精密度和准确度时,也会进行对比研究以评估实验室间的差异(也就是,重现性)。在进行对比研究时,应当要尽可能地使用同一批号的均匀样品。需对对比研究的结果进行统计分析和讨论,并对偏差进行解释。C. StatisticsFor information on statistical techniques used in ma
138、king comparisons, as well as other general information on the interpretationand treatment of analytical data, appropriate literature or texts should be consulted (see references) .C:统计关于用于对比分析的统计技术资料,和用于分析数据处理和解析的其它基本资料,可参见相关的文献(见参考文献)。IX. REVALIDATIONWhen sponsors make changes in the analytical pro
139、cedure, drug substance (e.g., route of synthesis), or drug product (e.g., composition), the changes may necessitate revalidation of the analytical procedures. Revalidation should be performed to ensure that the analytical procedure maintains its characteristics (e.g., specificity) and to demonstrate
140、 that the analytical procedure continues to ensure the identity, strength, quality, purity, and potency of the drug substance and drug product, and the bioavailability of the drug product. The degree of revalidation depends on the nature of the change. When a different regulatory analytical procedur
141、e is substituted (e.g., HPLC for titration), the new procedure should be validated (see section VII).IX 再验证当发起人对分析方法,原料药(比如,合成路线),或制剂(比如,组分)作了更改的话,则需要对分析方法进行重验证。进行重验证是为了确保该分析方法仍然保持其特性(比如,专属性),并论证说明该分析方法仍然能确保原料药和制剂的同一性,浓度/剂量,质量,纯度和功效,及制剂的生物利用度。重验证的程序取决于该变更的性质。当使用了另一个法定分析程序的话(比如,用HPLC代替了滴定法),则新的分析方法也需
142、要验证(见第VII章)。If during each use an analytical procedure can meet the established system suitability requirements only with repeated adjustmen14/ to the operating conditions stated in the analytical procedure, the analytical procedure should be reevaluated, amended, and revalidated, as appropriate.FDA
143、 intends to provide guidance in the future on postapproval changes in analytical procedures.如果在每次使用时,都必须要对分析方法中所述的操作条件进行反复调整,才能使其符合系统适应性要求的话,则该分析方法需要适当进行重新评估,修正和重验证。X. METHODS VALIDATION PACKAGE: CONTENTS AND PROCESSINGPart of the methods validation process may include FDA laboratory analysis to dem
144、onstrate that an analytical procedure is reproducible by laboratory testing. A methods validation package (see X.A) and samples (see X.B) will be needed for this process.A.
