How to Build a Post-Approval Change Management Protocol
Pre-agree how a future manufacturing change will be made and reported.
What a how-to is not
A how-to is SPEQ’s practitioner method, not a procedure. It does not replace your own SOP, it is not a validated approach, and the judgement calls in it belong to your quality unit.
A Post-Approval Change Management Protocol (PACMP) is a regulatory tool (ICH Q12) that lets a company describe a planned future change to an approved product — and the tests and criteria to support it — and agree it with the regulator in advance. It provides predictability, often allowing the change to be implemented with a lower reporting category once the protocol’s conditions are met.
- 1
Identify a suitable future change
Identify a change you can foresee and describe specifically — a site addition, a scale change, an analytical method replacement, a supplier change — rather than a general intention to make changes. The mechanism rewards specificity: a protocol covering a defined change with defined limits gives predictability, and one covering a category gives an authority little to agree to.
- 2
Describe the change and the strategy
Describe the change, the reason for it, and the strategy for demonstrating it has no adverse effect: the studies, the tests, the acceptance criteria, and the comparison against the current state. The acceptance criteria are the substance of the protocol, because the whole proposition is that you commit to them now and the authority accepts the change if they are met.
- 3
Propose the reporting category
Propose the reporting category that should apply once the protocol is executed and its criteria met, with the justification. The value of the mechanism is the reduction in reporting category and therefore in implementation time, and the proposal has to be reasoned rather than requested.
- 4
Agree with the regulator
Agree the protocol with the relevant authority before the change is made, and understand that agreement may differ between regions for the same protocol. A protocol agreed in one region and applied in another on the assumption of equivalence is the common error, and it converts a planned change into an unreported one.
- 5
Execute and report per the agreed protocol
Execute the change exactly as the protocol describes, meet the criteria, and report in the agreed category with the data. Where a criterion is not met, the protocol no longer applies and the change reverts to its normal reporting route — treating a near-miss as a pass is the failure that forfeits the mechanism for future use.
- !Writing a PACMP for a change too novel or uncertain to define acceptance criteria for in advance.
- !Acceptance criteria too weak to actually demonstrate no adverse impact.
- !Implementing the change without meeting all the protocol’s pre-agreed conditions.
- !Treating established conditions and reporting categories loosely, undermining the predictability the tool provides.
How to Build a Post-Approval Change Management Protocol: frequently asked questions
Common questions on build a post-approval change management protocol.
What is a PACMP?
A Post-Approval Change Management Protocol is an ICH Q12 regulatory tool in which a company describes a planned future change and the tests/criteria to support it, and agrees this with the regulator in advance — providing predictability and often a lower reporting category once the protocol’s conditions are met.
What is the benefit of a PACMP?
Predictability and often reduced regulatory burden: because the change and its supporting evidence are pre-agreed, the company can implement the change with a defined (frequently lower) reporting category once the criteria are met, rather than a full prior-approval submission at the time.
What are established conditions?
Established conditions (ICH Q12) are the elements of a manufacturing process and control strategy that are necessary to assure product quality and therefore require a regulatory submission to change. Clarifying them defines what actually needs reporting, which supports tools like the PACMP.
