Guidance for assessment and evaluation of changes to drug delivery systems

This document provides guidance for assessment and evaluation of planned changes to drug delivery systems that are integral with, packaged with, or cross-labelled for use with a specified medicinal product. This document is applicable to the drug delivery system's lifecycle from registration clinical studies to end-of-life. This document is applicable to the assessment of changes within the following drug delivery systems: — needle-based injection systems for medical use; — aerosol drug delivery devices; — needle-free injectors for medical use. NOTE These are covered by the ISO 11608 series, ISO 20072 and ISO 21649, respectively. This document might also be useful for assessing and evaluate changes to other drug delivery devices or systems. Examples of changes that are within the scope of this document include but are not limited to the following: a) the same route of administration (e.g. change resulting in including a marketed prefilled syringe to an autoinjector); b) changes to the drug delivery system design (e.g. change in configuration or layout of electrical and mechanical components); c) changes to the medicinal product that affect the drug delivery system; including the primary container closure (e.g. viscosity, particle size); d) changes in production or handling of the drug delivery system (e.g. process scale, manual to automated assembly, glue bond to sonic weld, mould cavitation, sterilization, storage, transportation, work instructions or methods); e) changes in component materials or source of supply; f) changes in software, including changes related to cybersecurity, encryption and connectivity; g) changes in the user interface, including packaging; h) changes to labelling and/or instructions for use. Revisions or additions of software are within the scope of this document. The software can either be integrated into the physical drug delivery system, separate, or both. The applicability of this document to non-integrated software is relevant to the extent that those software changes can impact the drug delivery system and/or impact how users interact with it. Depending on the nature of the change, there can be additional assessments and resulting activities, which can be outside the scope of this document. This document does not provide guidance for defining the objective of the change, nor the various potential opportunities/options for fulfilling this objective.

Introduction
This document provides guidance to organizations wishing to implement a systematic approach to
assess and evaluate changes to needle-based injection systems, needle-free injectors and aerosol
delivery devices for medical use (see Clause 1) throughout their lifecycles. In particular, an organization
can use the approach for changes to the drug delivery system from entry into pivotal or registration
clinical studies through the end of commercial supply.
Due to the breadth of potential change circumstances, this document does not contain prescriptive
technical requirements for assessing and evaluating drug delivery system changes but rather provides
illustrative guidance for consideration.
This document does not replace or alter existing statutory and regulatory requirements for assessing
drug delivery system changes.
Prior to using the process outlined in this document, the organization should have determined the
objective of the change including the various opportunities/options for fulfilling the objective.
This document might also be useful for assessing and evaluating change to drug delivery systems other
than needle-based injection systems, needle-free injectors and aerosol delivery devices for medical use.
The process can be applied to multiple product lifecycle stages, including design and development,
production, storage and distribution, installation, servicing and final decommissioning/disposal of
the drug delivery system or associated activities (e.g. up-dating of software). It can also be used by an
organization's suppliers and external parties (e.g. raw materials, components, subassemblies, medical
devices, sterilization services, calibration services, distribution services, maintenance services).
This document is not intended to replace or alter quality management systems, risk management,
or usability engineering requirements in assessing these changes. Rather, it provides a common
framework using a scientific and risk-based approach consistent with
[4]
— ISO 13485 ,
[5]
— ISO 14971 , and
[8]
— IEC 62366-1 .
Although this process focuses on user safety and drug delivery system performance, it also addresses
lifecycle management and includes consideration of appropriate medicinal product guidance (e.g. ICH
Q8, ICH Q9, ICH Q10 and ICH Q12). This will help assess the potential impact of changes on the quality,
safety, and efficacy of the finished product for the target patient population.
Over the course of a finished product's lifecycle, there will be a broad array of drivers for change. These
changes and their various design solutions can be motivated by, but are not limited to the following:
a) adverse event/complaint data;
b) voice of the customer, user feedback or market research;
c) usability studies;
d) changes in processes for production, production scale and supply chain logistics;
e) changes in material or source of supply;
f) impact of changes to the medicinal product that affect the drug delivery system.
This document provides examples of drug delivery system changes using a process flow (see Figure 1).
These examples and the conclusions provided are purely illustrative and are intended to provide
guidance on how to utilize this document.

ISO 20069:2019(E)

It is the responsibility of organizations to provide evidence that the approach adopted is commensurate
with the level of risk to ensure the quality, safety and performance of the drug delivery system. While
the focus of this document is the changed drug delivery system, it is also possible that changes to
the medicinal product might impact the drug delivery system (e.g. change in viscosity or volume of
medicinal product resulting in changed drug delivery system performance). It is also possible that
changes to the drug delivery system might impact the medicinal product (e.g. increased injection forces
resulting in changed treatment). As such, one key aspect of this process is assessing the change for
its potential impact on overall quality given the critical interface between the drug delivery system
and the medicinal product. Organizations should evaluate potential impact to the medicinal product
in accordance with relevant regulations and guidelines pertaining to medicinal products (e.g. ICH
guidelines) to ensure the quality, safety and efficacy.
The core of this document is the process flow, which attempts to guide an organization through a risk-
based approach based on drivers of change as mentioned above impacting the
— drug delivery system design,
— manufacturing process, and
— labelling and user interface.
The expectation is that such changes are evaluated through the risk assessment of how the change
could impact system form, fit and function (including medicinal product flow paths) such that users are
not negatively impacted in terms of quality, safety and performance of the drug delivery system. Given
that a single change can affect more than one of the change types (e.g. a material change can also drive
a process change), all change types should be assessed and evaluated.
The identification, analysis, evaluation and control of change are common regulatory requirements
in the post approval phase of a product’s lifecycle, but are also important in the clinical phase of
development. Organizations should demonstrate that as the drug delivery system design evolves, the
link between the drug delivery system and the medicinal product as tested in the clinical setting (for
which market authorization is granted or is intended) is maintained.

4 Process
4.1 General
4.1.1 Process framework
The process outlined in this document provides a framework to assess and evaluate changes to a drug
delivery system. It does not provide a framework to assess and evaluate changes to a medicinal product
(e.g. reformulation driven by adverse event data). However, if the change to a medicinal product has the
potential to impact the drug delivery system (e.g. reformulation increases viscosity impacting delivery
forces), then the framework should be used to assess and evaluate the impact on the drug delivery system.
The process is initiated when a change has been proposed for potential implementation. Every change
should be assessed based on the individual circumstances of the change. Where multiple changes are
occurring simultaneously or concurrently, they should also be assessed for their ability to interfere with
each other and/or to collectively impact the product in a manner different to their individual impacts.
The process should be divided into three phases as illustrated in Figure 1:
a) Phase A — Define and assess;
b) Phase B — Execute activities;
c) Phase C — Final evaluation.
Phase A, define and assess, starts with the thorough definition of the proposed change, i.e. the
purpose with and scope for the proposed change, a change description including the current state and
the proposed state after implementation. The next step is the identification of the change types based
on the information collected in the definition step. The last step of this phase is an impact assessment
on the performance, safety, stability, compatibility, process, usability, software, clinical data and
regulatory compliance.
Phase B, execute activities, consists of two steps, the planning and the execution of the planned
activities. During the planning step, all activities that need to be performed in order to prepare a proper
implementation of the change should be determined. These activities can include but are not limited to
design and development verification, design validation and process validation. The activities depend on
the change type (see 4.2.2) and its associated risks and on the specific properties and requirements of
the individual change and should be defined on a case by case basis. The planning step is concluded with
the confirmation of readiness to perform the planned activities. In the execution step, all the planned
activities are performed and completed, e.g. design and development verification work is conducted as
per the verification plan established in the planning step. Completion of the activities is a prerequisite
for change implementation and to enter the final evaluation Phase C of the change.
Phase C, final evaluation, includes an evaluation supporting a decision as to whether the change
should be implemented based on the results obtained in Phase B.
As an organization proceeds through the process, knowledge and perspective obtained through the
assessments (e.g. unacceptable risks, non-fulfilment of the objective or unforeseen difficulties in
implementing the change) and/or changes in business needs (e.g. cost/time) can result in a decision to
not proceed with the change. The basis for the decision should be documented.
Annex A provides an example of a template to guide the assessments and execution of the activities
included in Figure 1. Annex B provides examples of completed templates.

ISO 20069:2019(E)

Figure 1 — Process flow for assessment and evaluation of changes to the drug delivery system
4.1.2 Quality and risk management
The process should be performed within the organization's quality and risk management system
requirements. This process should be aligned with ISO 13485, in particular control of design and
development changes. Risk assessment should be performed and risk controls should be implemented
where needed in accordance with ISO 14971 during all phases of this process.
4.1.3 Relationships within the organization and with suppliers or external organizations
Due to the nature of drug delivery systems, it is common for separate functions within a single
organization responsible for the drug delivery system to have responsibilities for different aspects
of the finished product (e.g. formulation scientists responsible for the medicinal product aspects and
device engineers responsible for the drug delivery system aspects). When there is a change to the
drug delivery system, it is recommended to define internal roles and responsibilities for the change
process and to establish a cross-functional team comprising the relevant levels and functions within
the organization to be involved in each phase of this process.
Additionally, it is also common for one or more separate organizations to have responsibilities for
different aspects of the product (e.g. component suppliers, medicinal product manufacturer and device
manufacturer) and to work collaboratively. Where these relationships exist, it is essential to ensure
© ISO 2019 – All rights reserved 5

---------------------- Page: 11 ----------------------
ISO 20069:2019(E)

that roles and responsibilities with regards to notification of and approval of changes between the
parties are defined. Quality agreements with suppliers and other external organizations are one way
to ensure that changes that can impact the drug delivery system are transparent to the drug delivery
system owner.
Depending on the intended application, changes made within the defined specification range can still be
impactful for the drug delivery system. For example, shifting the nominal, as an improvement, within
the acceptable range for a particular attribute (e.g. silicone level) can impact the functionality of an
injection device. The assessment of this change from a supplier can have no impact as the component
still meet specification, but could result in a change in drug delivery system functionality.
4.2 Phase A — Define and assess
4.2.1 Define change (Figure 1, box 1)
This process is about defining the objective for the change and providing a description of the change
with the appropriate details. It can also be useful to identify what is not changing (e.g. no change to the
primary container and medicinal product flow path).
An objective for the change can include but is not limited to improved safety, improved performance, or
substitution of a component.
4.2.2 Identify change types (Figure 1, box 2)
The “current state” and “proposed state” of the drug delivery system as a result of the change should be
described. The change types should be identified based on the specifics of the change. The assessments
in Table A.1 can be useful to perform the preliminary change type identification.
Given that a single change can fall under more than one of the change types (e.g. a material change can
also be a process change), it should be assessed whether the change is included in each of the change
type categories to ensure an assessment.
Change types that should be identified include, but are not limited to the following:
a) Materials: Change of material of the drug delivery system components or its packaging including,
but not limited to, type, grade, chemistry, formulation, additives, colorants, supplier/sub-suppliers,
manufacturing materials and/or processing aids.
b) Form and fit: Change in physical attributes, such as component dimensions relative to interface/
interaction with other components and sub-assemblies.
c) Function: Change in system function as defined in the design input requirements and associated
design specifications (e.g. dose accuracy, environmental and mechanical robustness, functions that
support label claims such as deliverable volume).
d) Process change: Change in processes for production and handling of the drug delivery system.
Process changes include, but are not limited to changes to the component manufacture, sub-
assembly and system assembly processes including the following: process control, packaging,
different production sites, sterilization, environmental conditions and storage.
e) User interface change: Change impacting the user interface. User interface changes include
