ICH Q12 Pharmaceutical Product Lifecycle Management
Summary
The ICH Guideline Q12 on technical and regulatory considerations for pharmaceutical product lifecycle management was published in January 2020. The goal is to harmonize post-approval changes, to facilitate scientific innovation, and help to mitigate drug shortages. The integration of this guideline into European Union (EU) regulatory framework is pending. Some so called "tools and enablers" are proposed. Most of them are already implemented in the EU. New instruments are "established conditions (EC)" and the "product lifecycle management (PLCM)" document. These both instruments are elucidated, and a possible implementation strategy in the context of medicinal product approval and process validation is discussed.
Introduction
The ICH Q12 Guideline on technical and regulatory considerations for pharmaceutical product lifecycle management1 (in short: The ICH Q12 Guideline) was adopted in its final version in January 2020. Now the authorities and the member states involved have to implement it. The ICH Q12 Guideline puts in place framework conditions for the management of post-approval CMC2 changes. Its goal is to enable technical developments and at the same time to develop regulatory requirements on post-approval changes during the complete life cycle of medicinal products in a harmonised and effective way.
With the implementation of the ICH Q12 Guideline so-called tools and enablers are proposed. Their goal is to allow for a uniform and facilitated management of post-approval changes for the involved regulatory authorities and marketing authorisation holders.
The tools and enablers include:
- Categorisation of post-approval CMC changes
- Established conditions (ECs)
- Post-approval change management protocol (PACMP)
- Product lifecycle management (PLCM) document
- Pharmaceutical quality system (PQS) and change management
- Relationship between regulatory assessment and inspection
- Structured approaches for frequent CMC post-approval changes
- Stability data approaches to support the evaluation of CMC
Some of these proposed instruments (tools and enablers) are already put into practice for the EU:
- Categorisation of post-approval CMC changes: The categories for variations to the terms of marketing authorisations are defined (minor variation of type IA, minor variation of type IB, major variation of type II, extension of a marketing authorisation) 3.
- Post-approval change management protocol (PACMP): The concept of post-approval change management protocol related to active substances and finished products is established in the implementation guidelines to Regulation (EC) No 1234/20084, and described in the annexes ID and IE of the ICH Q12 Guideline in its possible forms5.
- Pharmaceutical quality system (PQS) and change management: The pharmaceutical quality management and change management are defined in their different forms in the EU Guidelines to Good Manufacturing Practice and in other regulations6,7,8,9,10,11. Further information is contained in the ICH Guideline Q10 Pharmaceutical Quality System12 which is established with Part III of the EU Guidelines to Good Manufacturing Practice.
- Relationship between regulatory assessment and inspection: The relationship between assessment of the dossier of the marketing authorisation (regulatory assessment) and inspections at manufacturers of active substances, finished products and medicinal products is already regulated on EU level and on national level (cf. articles 111, 122 and 125 of Directive 2001/83/EC13 as well as §§ 64, 68 AMG14 and §§ 12, 13 AMGVwV15). A practical example for this is the joint inspection of the responsible federal authority (for Germany: Paul-Ehrlich- Institut) in the case of inspections of manufacturers of blood preparations (second sentence of § 64 (2) AMG).
- Structured approaches for frequent CMC post-approval changes: The implementation guidelines to Regulation (EC) No 1234/2008 specify a structured approach for individual or several variation(s) to the terms of marketing authorisations. Any conditions to fulfil and documents to submit are specified for all possible variations. Additionally, a proposal for structurally to be planned post-approval changes of analytical methods is made in Annex II of the ICH Q12 Guideline.
- Stability data approaches to support the evaluation of CMC: The implementation guidelines of Regulation (EC) No 1234/2008 as well as Part I Chapter 6.33 of EU Guidelines to Good Manufacturing Practice (on-going stability programme) state the necessity to plan or to submit appropriate stability tests together with variations.
A review and where necessary an adjustment of the rules already applicable in the EU to the philosophy of the ICH Q12 Guideline is still pending.
By contrast, the concept and the legal classification of the ECs and of the resulting PLCM document are not established in the valid EU body of legislation (EUDRALEX16).
Established conditions and product lifecycle management (PLCM) in the EU legislative area
The discrepancy between the legal situation in the EU and the requirements of the ICH Q12 Guideline as concerns the ECs and the PLCM document are addressed in the Note on EU implementation of ICH Q1217:
The ICH Q12 Guideline refers to this required or necessary information as 'Established Conditions' (ECs). While this term does not exist in the EU variation legal framework, generally speaking, Established Conditions mirror information and quality characteristics that are subject to a variation, as described in the EU Variation Regulation (EC) No 1234/2008 (as amended) and associated EU Variation Guidelines. However, additional scientific risk-based approaches to defining Established Conditions and associated reporting categories […] and the Product Lifecycle Management (PLCM) Document […] are not considered compatible with the existing EU legal framework on variations. It is important to note that the legal framework always takes precedence over technical and scientific guidelines. More specifically this means that the definition of Established Conditions and their reporting categories must follow the requirements laid down in the current EU Variations Regulation and associated EU Variations Guidelines. […] Irrespective of the above, the tools and concepts in the ICH Q12 Guideline that are not foreseen in the EU legal framework will be considered when this framework will be reviewed. In the meantime, the European Commission, together with the EMA and the National Competent Authorities, will continue to work on the implementation of the ICH Q12 Guideline within the existing EU legal framework. |
Hence, this Note on EU implementation of ICH Q12 is to be understood as a declaration of intent. The Note implies that not legally defined tools and enablers such as ECs or the PLCM document will also be included in the body of laws of the EU concerning pharmaceutical legislation sooner or later. But currently neither the ECs nor the PLCM are applicable in the EU. This raises the question about the form they will take and about the legal adjustments in the EU that will be required for the implementation of the ECs and the PLCM.
Established conditions - definition according to the ICH Q12 Guideline
Established Conditions "mirror information and quality characteristics that are subject to a variation, as described in the EU Variation Regulation (EC) No 1234/2008 (as amended) and associated EU Variation Guidelines". This means that here the marketing authorisation has to be considered.
The information to be included in the application for a marketing authorisation are clearly defined18,19,20. The common technical document (CTD)21 is the key element of the marketing authorisation - apart from the administrative information about the marketing authorisation holder, the name of the medicinal product etc. This document contains the required information on the manufacture and quality control of the active substances and excipients used and of the medicinal product. A fundamental subdivision of the data is possible in clearly defined material specifications (active substances and excipients, intermediate products, medicinal products), process parameters of manufacture and testing as well as supporting documents (development reports, risk analyses, validation reports etc.).
But what are the established conditions in the CTD?
The ICH Q12 Guideline contains the following definition22:
ECs are legally binding information considered necessary to assure product quality. As a consequence, any change to ECs necessitates a submission to the regulatory authority. |
This binding information relates to product quality. This means that the question from above about the information from the dossier of the marketing authorisation that is part of the ECs remains unanswered. To that end the teleological interpretation of the set of rules makes sense. This is the question "What is the rule's intention?". The ICH Q12 Guideline gives the following answer23:
The concept of ECs provides a clear understanding between the MAH and regulatory authorities regarding the elements to assure product quality and that involve a regulatory communication, if changed. This guideline describes how ECs are identified as well as what information can be designated as supportive information that would not involve a regulatory communication, if changed. In addition, guidance is included for managing revisions of the ECs. |
This means that the ECs have to be understood as the information regarding the quality of the medicinal product agreed upon by the marketing authorisation holder on the one hand and the authority granting the approval on the other hand. Furthermore, variations of the ECs are subject to the rules of Regulation No 1234/2008 ("Variation Guideline").
Hence, all information on material specifications, process parameters of manufacture and testing, in-process controls, run times etc have to be understood as ECs. Development reports, risk analyses, validation reports on the other hand are covered by the concept "supportive information" according to the ICH Q12 Guideline since they justify the parameters defined for manufacture and quality control and the limits set for these parameters. Annex IA and Annex IB of the ICH Q12 Guideline contain examples for ECs for the manufacturing process.
"Established conditions" in the US American legislative area
A brief digression to the USA shows that the wording for relevant concepts for changes of approvals by the US American FDA already exist.
21CFR314 Applications for FDA approval to market a new drug §314.70 Supplements and other changes to an approved NDA. (a) Changes to an approved NDA. (1)(i) Except as provided in paragraph (a)(1)(ii) of this section, the applicant must notify FDA about each change in each condition established in an approved NDA beyond the variations already provided for in the NDA. |
The same is applicable to biological drugs falling under the approval of the US American FDA.
21CFR601.12 Changes to an approved application §601.12 Changes to an approved application. |
How are "established conditions" defined?
Paramount for the definition of ECs is a risk-based process understanding. This process understanding is based on the fundamental consideration which material attributes of the active substances and excipients used are relevant for the final product quality, which process parameters are critical and which controls (in-process controls, final controls) are required at which steps in the process of manufacture. This assessment can only rarely be deduced from a FMEA24 risk analysis. A consecutive analysis of each process step (unit operation) following HACCP25 risk analyses based on the results of development and experience reports is more suitable.
Basis for establishing ECs are thus the definition and identification of the following parameters:
- Critical quality attributes (CQA)
- Critical process parameter (CPP)
- Process control strategy (in-process controls, final controls)
The basic requirement for the definition of CQA and CPP can be found in Annex 15 Chapter 5.21 of the EU Guidelines to Good Manufacturing Practice26: "A process validation protocol should be prepared which defines the critical process parameters (CPP), critical quality attributes (CQA) and the associated acceptance criteria which should be based on development data or documented process knowledge."
Corresponding requirements concerning the definition and establishment for the pharmaceutical development can be found in the ICH Guideline Q8 R2 Pharmaceutical Development27.
For the establishment of ECs, the ICH Q12 guideline suggests two basic approaches. These will be presented in the second part of this article in the next issue of the GMP Journal.
