Phase 1
Data Collection and Scope Definition
1Define the review period and product scope
Twelve-month review period defined, typically aligned to calendar or fiscal year, with the specific product or product family in scope clearly identified.
21 CFR 211.180(e)
↓
2Identify all applicable data sources
Every data source required by 21 CFR 211.180(e) and applicable internal procedure identified and confirmed accessible before compilation begins.
21 CFR 211.180(e)
↓
3Assign cross-functional responsibility
Data compilation responsibilities assigned across quality, manufacturing, and other relevant functions, reflecting that no single function holds every required data stream.
ICH Q10
↓
4Confirm data completeness
Compiled data checked for completeness against the full review period before analysis begins, since a gap in the underlying data undermines the entire review's conclusions.
21 CFR 211.180(e)
Phase 2
Data Compilation and Trend Analysis
5Compile batch disposition data
Total batches manufactured, released, rejected, and reworked during the period compiled, with rejection rate calculated and compared against prior periods.
21 CFR 211.180(e)
↓
6Compile quality event data
Deviations, OOS, OOT findings, and complaints compiled and categorized by type, providing the basis for trend analysis in the next phase.
21 CFR 211.180(e)
↓
7Compile stability and change control data
Ongoing stability results and implemented changes compiled, with any stability trend or change-related quality impact flagged for closer evaluation.
21 CFR 211.166 · 211.180(e)
↓
Do compiled trends indicate a need for further investigation?
YES → Escalate for focused review
NO → Proceed to evaluation
Phase 3
Evaluation and Conclusion
8Evaluate against the prior year's APR
Current period trends compared against the prior APR to identify whether performance is improving, stable, or declining year over year.
ICH Q10
↓
9Assess adequacy of specifications and controls
Current specifications, in-process controls, and manufacturing procedures assessed for continued adequacy in light of the year's actual performance data.
21 CFR 211.180(e)
↓
10Draw conclusions on state of control
Formal conclusion drawn regarding whether the product and process remain in a validated state of control, supported by the compiled evidence.
ICH Q10
Phase 4
Reporting, CAPA, and Follow-Up
11Compile and approve the formal report
Written APR report compiled covering all required elements and formally approved by the quality unit before distribution.
21 CFR 211.180(e)
↓
12Initiate CAPA for adverse trends
Corrective and preventive actions initiated for any adverse trend or conclusion identified during the review, tracked through the site's standard CAPA system.
ICH Q10
↓
13Track CAPA and carry forward open items
CAPA tracked to closure, with any items still open at year-end carried forward and explicitly referenced in the following year's APR.
ICH Q10
Required APR Content (21 CFR 211.180(e))
Records Reviewed for Quality Standards
A written review of records for each drug product to evaluate quality standards, identifying the need for changes in specifications or manufacturing or control procedures.
21 CFR 211.180(e)
Minimum Annual Frequency
Review conducted at least annually, with each product reviewed on its own schedule rather than all products reviewed simultaneously on a single fixed calendar date.
21 CFR 211.180(e)
Change Justification Basis
The review's findings serve as the documented basis for determining whether any change to specifications or procedures is warranted going forward.
21 CFR 211.180(e)
Adverse Trend Response Steps
Step 1 - Characterize the trend clearly
Describe precisely what is trending adversely, whether rejection rate, a specific deviation category, or a complaint type.
Step 2 - Determine whether the trend was previously known
Check whether this trend was already flagged through routine trending outside the APR cycle, or whether it is a new finding.
Step 3 - Assess root cause at the annual level
Investigate whether a systemic factor, rather than isolated individual events, is driving the year-over-year pattern.
Step 4 - Initiate CAPA with defined ownership
Open a formal CAPA with a clearly assigned owner and target timeline, distinct from any individual event-level CAPA already in place.
Step 5 - Define success criteria for the next cycle
Establish what improvement would look like by the next APR cycle, giving the following year's review a clear basis for assessing whether the action was effective.
Data Source Requirements
Complete period coverage
Data spanning the entire twelve-month review period without gaps, even where responsibility for different data streams sits with different functions.
Consistent categorization
Deviation, complaint, and other event categories applied consistently year over year, supporting genuine trend comparison rather than an apples-to-oranges review.
Traceable source records
Every summarized figure in the APR traceable back to its underlying source record, supporting verification during an inspection.
Prior year cross-reference
Current period data presented alongside, or explicitly compared to, the prior year's figures to make genuine trend evaluation possible.
