Zielsetzung
Hintergrund
Q2(R1) Revision
The current Q2(R1) „Guideline on Validation of Analytical Procedures: Text and Methodology“ does not yet include modern analytical methods (e.g. near infrared (NIR) spectroscopy or Raman spectroscopy). This gap can lead to insufficient validation data for submissions and thus to additional official queries and thus to a delay in the approval of the application. This applies in particular to methods based on multivariate models, a category for which there is currently no guidance in ICH Q2(R1). NIR or Raman spectroscopy is often used in process control and real-time release testing (RTRT) using multivariate analytical methods. Therefore, the revision of ICH Q2(R1) will specifically serve the validation of modern analytical methods, including a discussion of statistical aspects. Common validation characteristics for methods such as NIR, nuclear magnetic resonance spectroscopy (NMR) and hyphenated techniques such as CE-MS, CE-ICP-MS, LC-NMR, GC-MS, LC-MS will also be considered.
Q14 Analytical Method Development Guide
As there is no ICH guideline for the development of analytical methods yet, it is often the case that applicants only report on analytical validation results and seldom present a performance evaluation with analytical development results. This makes communication with the regulatory authorities more difficult, especially when unconventional analytical methods are used (e.g. RTRT and multivariate models for process control). In addition, the lack of guidelines excludes the possibility for the applicant to provide a scientific basis for flexible regulatory approaches (e.g. Quality by Design (QbD) concept) to change analytical methods after approval.
According to ICH, the new directive is proposed to harmonise the scientific approaches to analytical process development and to provide the principles for the description of the analytical process development process. The new guideline should improve communication between industry and regulators and allow for more efficient, sound scientific and risk-based authorisation and change management for post-authorisation changes to analytical methods.
Issues to be addressed
Q14 Analytical Procedure Development guideline
Main technical and scientific elements, which require harmonization, include:
- Submission of analytical procedure development and related information in CTD format,
- The concept and strategy of enhanced approaches for analytical procedures,
- Performance criteria of analytical procedures,
- In line with ICH Q8 to ICH Q12, a greater understanding of analytical procedures can create the basis for more efficient, sound science and risked-based lifecycle management (e.g., using analytical QbD (AQbD) principles),
- Key elements and terminology,
- Demonstration of suitability for RTRT.
For procedures reliant on multivariate methods the following will be addressed:
- Definition of validation characteristics applicable to multivariate methods which may differ with the area of application (e.g., identification vs. quantitation, batch vs. continuous process, dosage form assay vs. blending monitoring),
- Important method parameters (e.g., the number of latent variables) established during method development,
- Robustness which is well understood, however does not have a quantitative measure,
- Inclusion of post-approval verification and maintenance considerations as a part of the validation,
- Requirements for validation data sets.
