FDA CAPA Investigation and Process Qualification Resolution Enabling Relaunch of Class III Spinal Implant Device After Manufacturing Relocation

1. The Situation

A company wants to move its newly acquired manufacturing facility closer to its headquarters. The facility manufactures a Class III spinal implant device, among other things. Since manufacturing also involves outsourced processes, the move requires shifting outsourced process steps to new vendors.

Both in-house and outsourced manufacturing processes require new validation. Prior to involvement, multiple Process Qualification (PQ) efforts have failed. Without an acceptable PQ, nothing out of the manufacturing facility can be sold - which is obviously a big problem.

2. The Solution

Proposed an examination of the entire manufacturing process - including starting materials, internal processes, and final testing. A Quality System Engineer with extensive manufacturing and R&D experience led a Corrective Action Preventive Action (CAPA) Investigation. CAPA is but one part of a Quality Management System (QMS).

The complexity of the manufacturing process as well as the need to involve resources from several departments across the company required obtaining Executive Management buy-in. Once they had that, recommended creating a Project Charter.

3. Detailed Investigation and Technical Analysis

Examined the entire spinal implant manufacturing process, comprising eleven main process modules and hundreds of individual process steps, supplier processes, and the Process Failure Mode and Effect Analysis (pFMEA).

Investigation drove the conduct of various surface analysis tests on key components and an examination of a newly instituted cleaning step which included:

• Scanning electron microscopy (SEM)
• Energy Dispersive X-Ray Spectroscopy (EDS); a chemical microanalysis technique
• Fourier-transform infrared spectroscopy (FTIR) in both reflection and Attenuated Total Reflection (ATR) mode

Working with an analytical chemist at a Surface Analysis company, detected three surface contaminants. Identified the specific process steps that introduced the three contaminants, recommended Containment Actions, and determined a Root Cause. Then recommended Corrective Actions and Opportunities for Improvement (OFI) to mitigate future risk. Also reviewed test results to verify that the material and surface properties of the components did not statistically change. The results indicated that no new risks arose due to the introduction of the cleaning process step.

4. Implementation of Corrective Actions and Validation Updates

Implemented the recommended Corrective Actions and Opportunities for Improvement across the eleven main process modules. Updated design control procedures, process validation protocols, and quality system documentation to align with the relocated and re-validated manufacturing setup. Ensured all in-house and outsourced steps met the new validation requirements through rigorous testing and documentation.

5. Project Management and Cross-Functional Coordination

Obtained Executive Management buy-in early to secure resources from multiple departments. Developed and executed a Project Charter to guide the CAPA investigation and PQ resolution. Coordinated closely with internal teams and new vendors to integrate changes without disrupting ongoing operations.

6. Regulatory and Compliance Outcomes

The enhanced quality system fully addressed prior gaps in process validation and contamination control. The completed PQ satisfied both internal requirements and regulatory expectations for the Class III spinal implant device.

7. Results and Benefits

Work resulted in the successful completion of the PQ and made it possible to relaunch the spinal implant. Sales restrictions were lifted, allowing the product to return to the market. The manufacturer achieved a more robust and compliant manufacturing process with reduced risk of future validation failures, improved contamination controls, and strengthened overall quality system performance.
