In addition the FDA has included requirements for method transfer in its new guidance from 2015 on validation of analytical methods. If the acceptance value is > L1%, test the ature over a period of about 30 minutes, taking precautionsnext 20 units, and calculate the acceptance value. Knowing how method performance impacts out-of-specification rates may improve quality risk management and product knowledge. USP Requirements for Dissolution Validation Dissolution is a Category III Test in USP <1225> Validation of Compendial Methods and Requires: •Accuracy •Precision •Specificity •Detection Limit •Quanititation Limit •Linearity •Range . No mention of acceptance criteria is made in the standard, although it is implied there will be acceptance criteria generated (3). ICH, Q9 Quality Risk Management (ICH, 2006). As long as the curve remains within +-1.96 of the studentized residuals, the response of the assay is linear. Methods with excessive error will directly impact product acceptance out-of-specification (OOS) rates and provide misleading information regarding product quality. It is expected that the robustness study will be used to determine settings and ranges that will ensure bias less than 10% of tolerance and repeatability less than 25% of tolerance. For Figure 1, one is 95% sure this assay is linear up to 30 ug/mL. The updated USP standards are critical components of process and method validation within pharmaceutical and biopharm facilities. HC’s Acceptable Methods Guidanceprovides useful guid-ance on methods not covered by the ICH guidelines (e.g., dissolution, biological methods), and provides acceptance criteria for validation parameters and system suitability tests for all methods. VALIDATION OF EXTRACTABLES AND LEACHABLES METHOD FOR A SULFUR-CURED ELASTOMER 4 In addition, this final guidance document also gives the reference to the US Pharmacopeia (USP) General Chapters Validation of Analytical Procedures <1225>, Verification of Compendial Monographs <1226>, … Acceptance criteria for the range should be based on the following: Range of the method should be less than or equal to 120% of the USL and be demonstrated to be linear, accurate, and repeatable. Save the studentized residuals from the curve. Also the FDA has released an official guidance on how to conduct and document method transfer. 5], Mean = Average of specific concentrations of interest [Eq. Table I: Method validation and acceptance criteria. A robustness study has no acceptance criteria; however, the robustness study should indicate the method is accurate and repeatable at the recommended best set point and across a defined range. Recommended acceptance criteria for analytical methods for bias are less than or equal to 10% of tolerance. Lifecycle management has also been … In order to provide harmonized regulation thorough out … The following are brief quotes from the guidance documents regarding acceptance criteria: There are two elements for evaluating a method: determination of the result (bias, repeatability, etc.) The penalty for solely depending on CV or % recovery is a method may be developed and qualified without knowing if it is fit-for-purpose or fit-for-use, and knowing its associated influence on product acceptance and release testing. The following is a summary of the elements that need acceptance criteria and what elements are ‘report only’ or need to be documented in a development report (see  Table I). USP, <1033> Biological Assay Validation, USP 38 (USP, 2010). For a bioassay, they are recommended to also be less than or equal to 10% of tolerance. Effectively the question is: how much of the specification tolerance is consumed by the analytical method? 3. This seminar will give a good understanding of USP and FDA requirements and provide … As repeatability error increases, the out of specification [OOS] rate increases. This concept has been well established for many years in chemical, automotive, and semiconductor industries and is recommended in the United States Pharmacopeia (USP) <1033> and <1225> (4, 5). The re- to avoid uptake or loss of moisture. All rights reserved. The updated USP 61 reference includes stronger testing requirements for the total aerobic microbial count (TAMC) and the total combined yeasts and mold counts (TYMC). VALIDATION OF EXTRACTABLES AND LEACHABLES METHOD FOR A SULFUR-CURED … References Newby, P. (2005) Implementation, validation and registration of rapid microbiological methods. Conversely, at high concentrations, the method will often appear to be performing well-as the % CV and % recovery appear to be acceptable-when it is actually unacceptable relative to the product specification limits it will be used to evaluate. The Validation Protocol defines the tests to be run, the data to be acquired for each test and the acceptance criteria for each test (figure 4). Also presented are acceptance criteria for each validation parameter. A stability study on critical reagents such as standards and/or bulk materials has no acceptance criteria; however, the study should indicate the expiry of pre-mixes, bulks, or standards. z. A companion Stimuli article explains the rationale and content of this proposed revision. Tolerance = Upper Specification Limit (USL) - Lower Specification Limit (LSL) [Eq. R-square of a curve comparing the theoretical concentration to the signal from the method. Moving from relative measures of analytical method goodness to measures that have product relevance links method performance to CQAs and their associated specification limits in a way that nothing else will. Calculate the acceptance containing 25 mg or more of a drug substance compris-value (see Table 2). Figure 2: Influence of repeatability on capability (out-of-specification [OOS] rate in parts per million [PPM]). USP Requirements for Dissolution Validation ... •Acceptance criteria for each of the elements •Empty tables to be filled out . The following are the recommended evaluation and acceptance criteria. In order to provide harmonized regulation thorough out … Repeatability is the standard deviation of repeated (intra-assay) measurements (see Figure 2). have strong recommendations about SST performance (e.g. Analytical methods establish acceptance criteria and monitor quality of drug products throughout their expiry. These must be considered carefully. A Laboratory Guide to Method Validation and Related Topics: The Fitness for Purpose of Analytical Methods, ISBN 0-948926-12-0, Teddington, Middlesex, United Kigdom. Method Validation and Transfer for Biotechnology Products • Describes method lifecycle steps from design and development to qualification and transfer • Has sections on – Assessment of method validation readiness – Risk assessment process – Setting method validation acceptance criteria – Analytical method validation according to ICH Q2 Method validation of analytical method is a federal requirement for current good manufacturing practice ( cGMP). USP 31 Microbiological Tests / ... methods, may be used, provided that their equivalence to the Pharmacopeial method has been demonstrated. BACKGROUND Well established validation guidelines for bioanalytical methods A laboratory should absolutely not skip the SST because of having already an AIQ procedure in place. Further, the traditional approach will often falsely indicate a method is performing poorly at low concentrations, when in fact it is performing excellently. Method validation of analytical method is a federal requirement for current good manufacturing practice (cGMP). Figure 3: Accuracy to precision modeling. The advantage is the lab can develop and evaluate the goodness of a method independent of the product and the associated acceptance criteria it is intended to measure. Acceptance Criteria: %RSD for each target extractable ≤ 10% Chromatographic Resolution and Tailing Factor (USP) Utilizing the analyses accomplished for Instrument Precision, chromatographic resolution and Tailing Factor (USP) between appropriate peak pairs were be determined. method validation evince the quality andconsistency of the analytical results obtained in future determinations in real samples, whereas the operational/eco- nomic parameters appraise if the method can be used for routine analysis. To control the consistency and quality of pharmaceutical products, analytical methods must be developed to measure critical quality attributes (CQAs) of drug substance/drug product. • For off-line tests, allow for innocuous contamination that results from CO 2 (HCO 3-and H+) • Eliminate the variations of temperature-compensation methods. This is a big mistake as both the United States Pharmacopoeia (USP) as well as the European Pharmacopoeia (Ph. ICH, Q6B Specifications: Test Procedures and Acceptance Criteria for Biotechnological/Biological Products (ICH, March 1999). HC’s Acceptable Methods Guidanceprovides useful guid-ance on methods not covered by the ICH guidelines (e.g., dissolution, biological methods), and provides acceptance criteria for validation parameters and system suitability tests for all methods. Mathematically, the variation of any drug product or drug substance is the additive variation of the method and test sample being quantitated. Verification of compendial methods ; Method transfers - good to know. Develop SOPs for executing method in routine . J. Guerra, Pharm. The HPLC-UV method passed the validation and the predefined acceptance criteria, and results are summarized in Table 3. Compendial guidance on method validation, verification and transfer: USP General Chapters 1033, 1092, 1210, 1224, 1225, 1226 and 1467 Ph. FDA, Analytical Procedures and Methods Validation for Drugs and Biologics, Guidance for Industry (CDER, July 2015). 9. 11. % coefficient of variation (CV) = (repeatability/mean)*100, % recovery = (measured concentration/standard concentration)*100. Bias may be evaluated relative to the tolerance (USL-LSL), margin, or the mean: Bias % of Tolerance = Bias/Tolerance*100,  Bias % of Margin = Bias/(USL-Mean or Mean - LSL) One Sided Bias % of Mean = Bias/Mean*100. USP chapter 60> builds upon the test methods and acceptance criteria recommended in USP chapters 61>, 62>, and 1111> to provide a relatively simple and reliable test for the detection of Bcc associated with pharmaceutical manufacturing processes. Setting acceptance criteria based on OOS rate impact is more meaningful and supported by both FDA and USP guidance. The course includes workshops to help attendees plan method validation and to select appropriate acceptance criteria, as well as checklists for validation protocol and analytical method contents.
