A Corrective and Preventive Action (CAPA) response to the FDA must address the root cause of an identified issue, clearly outline the actions taken to correct it, and prevent recurrence. The FDA expects that CAPA responses adhere to 21 CFR Part 820 (Quality System Regulation) for medical devices, or 21 CFR Part 211 (cGMP for finished pharmaceuticals), depending on the nature of the business.
Here is an example of a CAPA response that could meet FDA expectations for a medical device manufacturer:
Subject: CAPA Response to Observation #X from FDA Form 483
Date: [Insert Date]
FDA Reference: Observation #X from FDA Form 483 issued on [Date]
1. Problem Description and FDA Observation:
During the FDA inspection conducted from [Date] to [Date], the inspector noted the following issue, documented as Observation #X on FDA Form 483:
Observation: Failure to establish and maintain procedures for implementing corrective and preventive actions, as required by 21 CFR 820.100(a). Specifically, CAPA #12345, initiated to address non-conformances in Product XYZ, did not identify the root cause of the issue or include appropriate corrective and preventive actions.
2. Immediate Correction:
Upon receiving FDA Form 483, the following immediate actions were taken:
- Affected product lots (Lot #ABC123) were placed on hold.
- A product recall was initiated for the impacted batches to avoid risk to patients.
- Manufacturing of Product XYZ was suspended until the CAPA was fully investigated and implemented.
3. Root Cause Investigation:
We initiated a comprehensive root cause analysis in compliance with 21 CFR 820.100(a)(2), using the following methodologies:
- Failure Modes and Effects Analysis (FMEA) to identify potential failure points in the production process.
- Interviews with production operators and review of batch records from the last 12 months to identify deviations.
- Laboratory testing of retained samples.
The root cause of the non-conformance was traced to a malfunction in the automated dispensing system that was incorrectly calibrated, leading to incorrect measurements of a critical raw material. This was confirmed by historical review of machine calibration logs and operator error reports.
4. Corrective Actions:
The following corrective actions have been implemented, per 21 CFR 820.100(a)(3) and 820.100(a)(4):
- The automated dispensing system was recalibrated and validated, with detailed verification performed to ensure accuracy within acceptable limits.
- Affected products (Lot #ABC123) were recalled, and impacted devices were retrieved from the market.
- Operators involved in the process have been retrained on equipment calibration procedures and the importance of reporting equipment malfunctions.
5. Preventive Actions:
To prevent recurrence, the following preventive actions have been established, as required by 21 CFR 820.100(a)(5) and 21 CFR 820.100(a)(6):
- A new calibration schedule has been implemented, requiring more frequent validation of the dispensing system, in line with ISO 13485 and internal procedures.
- An automated alert system has been added to notify the quality team when calibration falls outside the acceptable range.
- Updated SOPs have been distributed to ensure that deviations related to calibration are flagged and addressed immediately.
6. Verification of Effectiveness:
We have established monitoring procedures per 21 CFR 820.100(a)(7) to ensure the effectiveness of the corrective and preventive actions. The verification plan includes:
- Quarterly audits of the dispensing system’s calibration status and the production line for the next 12 months.
- Periodic reviews of operator training effectiveness through competency tests.
- Review of non-conformance trends at the monthly CAPA review board meeting to detect any emerging issues.
7. Conclusion:
All CAPA-related actions have been completed, and we are confident that the risk of recurrence has been minimized. Documentation of all actions taken has been archived in accordance with 21 CFR 820.100(b).
We respectfully request FDA’s approval of the above CAPA actions and are available to provide any additional documentation or clarification if required.
Sincerely,
