【正文】
有關原料藥和產(chǎn)品的雜質檢測規(guī)程中,應當包括雜質的名稱和檢測位 /標志(例如,保留時間 RT,相對保留時間 RRT),以及雜質的種類(比如工藝降解產(chǎn)物,賦形劑降解產(chǎn)物),如有可能,還應當指明檢測限 DL或定量限 QL。也可以在原料藥檢測中設置 DL和 QL。 Reporting of anic 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 anic impurities for the drug product or drug substance is the sum of all impurities equal to or greater than their individual QL. See remendations regarding appropriate QLs in FDA impurities guidances (see references). Inanic impurities and residual solvents should also be addressed. 有機雜質的報告中,應當包括: 有記載的已經(jīng)過確認的雜質的名稱; 有記載但未經(jīng)過確認雜質的(檢測)位 /標志; 所有的沒有記載的雜質,以及; 總雜質??傆袡C雜質是指所有達到或超過其自身定量限度的雜質的總量。在這里可以參考 FDA雜質指南文章中有關判定定量限度的內容(看后面的參考)。無機雜質和溶劑的殘留,也應該被提到。 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. 對于產(chǎn)品以及原料藥的工藝雜質也可以不包括在報告中,除非分析規(guī)程和控制環(huán)節(jié)中描敘了一個可以被接受的原則,那么,在 產(chǎn)品制造和包裝過程中(包括貼簽)產(chǎn)生的雜質就要被提到。 The above reporting information may not be strictly applicable to all products (., biological, biotechnological, botanical, radiopharmaceutical drugs), but any significant process and productrelated impurities should be determined and reported. 并不是所有產(chǎn)品(比如,生物制劑、生物工藝制劑、植物制劑、放射制劑)的報告都必須嚴格按照以上談到的內容來寫,但是所有關鍵的工序以及產(chǎn)品相關的雜質都要有檢測和報告。 VII. METHODS VALIDATION FOR NDAs, ANDAs, BLAs, AND PLAs A. Nonpendial Analytical Procedures In an NDA, ANDA, BLA, or PLA, data must be submitted to establish that the analytical procedures used in testing meet proper standards of accuracy and reliability (21 CFR (a)(2)). Methods validation is the process of demonstrating that analytical procedures are suitable for their intended use. At the time of submission, the NDA, ANDA, BLA, or PLA should contain methods validation information to support the adequacy of the analytical procedures. VII. NDA, ANDA, BLA和 PLA中的分析方法驗證 A.非藥典分析方法 在 NDA, ANDA, BLA或 PLA 中,應當要遞交資料以說明檢測中所用的分析方法是滿足適當?shù)臏蚀_度和可靠性要求 (21 CFR (a)92))。 分析方法驗證 是個論述分析方法是適用于其擬定用途的過程。在遞交資料時, NDA, ANDA, BLA 或 PLA 中應當要包含分析方法驗證資料以支持分析方法的準確度。 The International Conference on Harmonisation (ICH) guidance Q2A Text on Validation of Analytical Procedures (March 1995) and Q2B Validation of Analytical Procedures: Methodology (November 1996) provide remendations on validation of analytical procedures. Analytical procedures outside the scope of the ICH guidances should still be validated. ICH指導原則 Q2A:分析方法驗證( 1995年 3月)和 Q2B:分析方法驗證:方法學( 1996年11 月)給出了分析方法驗證的建議。對于超出 ICH 指導原則范圍的分析方法也是需要驗證的。 1. Validation Characteristics Applicants should submit information on the validation characteristics of their proposed analytical procedures (see ICH Q2A and ICH Q2B). Although not all of the validation characteristics are needed for all types of tests (see section ), typical validation characteristics are: 申請者應當要送交其所擬定分析方法的驗證項目方面的信息(見 ICH Q2A和 ICH Q2B)。盡管不是對于所有類型的分析方法都需要進行所有的驗證項目(見第 章),但還是有典型的驗證項目,如 : Accuracy Precision (repeatability and intermediate precision) Specificity Detection limit Quantitation limit Linearity Range Robustnes 準確度 精密度(重復性和中間精密度) 專屬性 檢測限 定量限 線性 范圍 耐用性 2. Other Methods Validation Information Methods validation information should also include: Data to demonstrate the stability of all analytical sample preparations through the time required to plete the analysis. 分析方法驗證資料還應當要包括: 說明所有分析制備樣品在完成分析所需的時間內的穩(wěn)定性的資料。 Legible reproductions of representative instrument output or recordings (., chromatograms) and raw data output (., integrated areas), as appropriate. Instrument output for placebo, standard, and sample should also be provided (see section ). 清晰可讀的儀器代表性輸出和記錄資料(如色譜圖)和原始資料輸出(積分面積)。安慰劑,對照品和樣品的儀器輸出也 都是需要提供的(見第 )。 Representative calculations using submitted raw data, to show how the impurities in drug substance are calculated. Information from stress studies (see section ). Impurities labeled with their names and location identifiers (., RRT for chromatographic data) for the impurity analytical procedure. 代表性計算公式,以表明原料藥中的雜質是如何計算的。 (見 )。對于雜質分析方法,要標明雜質的名稱和位置標識符(如,色譜中的相對保留時間 RRT)。 For drug substances: A discussion of the possible formation and control of polymorphic and enantiomeric substances. Identification and characterization of each anic impurity, as appropriate. This information may not be needed for all products (., botanicals). Other impurities (., inanics, residual solvents) should be addressed and quantitated. 對于原料藥: 1. 討論可能會形成的異構體并討論異構體的控制。 對每個有機雜質進行適當?shù)臉俗R和界定。不是所有的產(chǎn)品(如,植物藥)都需要這些資料的。對于其它雜質(如無機雜質,殘留溶劑),應當要進行說明并定量分析。 Remendations on submitting information on impurities is provided in various FDA guidances such as the ICH guidance Q3A Impurities in New Drug Substances (January 1996).
