parameters, and ensuring that validation is properly conducted and documented during routine production.

Regulatory Affairs Team: Ensures that the concurrent validation process adheres to relevant regulatory requirements and guidelines.

4. Accountability

The Manufacturing Manager is accountable for ensuring that concurrent process validation is conducted according to this SOP. The overall compliance with this SOP is overseen by the Quality Assurance (QA) Manager.

5. Procedure

5.1. Developing the Concurrent Process Validation Protocol

1. The concurrent process validation protocol should outline the following:
   • Objective: To validate the manufacturing process while routine production continues, ensuring consistent quality and product specifications are met.
   • Scope: Define which stages of production are subject to concurrent validation (e.g., formulation, filling, crimping, packaging).
   • Critical Process Parameters (CPPs): Specify which process parameters will be monitored during the validation, such as temperature, pressure, filling volume, and spray rate.
   • Acceptance Criteria: Define the acceptable range for each CPP and quality parameter, including any thresholds for deviation.
   • Sampling Plan: Provide a plan for sampling and testing at specific intervals during the validation process. Ensure sufficient samples are taken to support valid conclusions.
   • Methodology: Describe the methodology for performing the validation during production, including how data will be collected and analyzed.
   • Documentation Requirements: Specify the records and forms that need to be completed during validation (e.g., batch records, deviation logs, process monitoring logs).
2. The protocol should be reviewed and approved by the QA team before being executed.

5.2. Executing the Concurrent Process Validation

1. During concurrent validation, the production team will continue normal manufacturing activities while adhering to the concurrent process validation protocol.
2. Critical process parameters (CPPs) should be continuously monitored during production runs. The following should be documented:
   • Batch identification and production details
   • Recorded values for each monitored CPP
   • Results from in-process quality testing (e.g., spray rate, fill weight)
   • Any deviations from established acceptance criteria and the corrective actions taken
3. Deviations observed during validation should be immediately documented in the Deviation Log (Annexure-1). The production and QA teams should investigate any deviations and implement corrective actions as necessary.

5.3. Documentation of Concurrent Process Validation

1. All validation activities should be documented accurately and promptly. The following documents should be created and maintained:
   • Concurrent Process Validation Report (Annexure-2), which should summarize the protocol, monitored parameters, test results, deviations, and corrective actions.
   • Process Monitoring Logs, documenting the critical parameters and quality control results during the validation runs.
   • Deviation Log (Annexure-1), documenting any deviations and corrective actions taken during the validation process.
2. Validation data should be reviewed by the QA team for completeness, accuracy, and compliance with the acceptance criteria.
3. The final concurrent process validation report should be signed and approved by the QA Manager and the Manufacturing Manager. All related documentation should be securely archived for future reference and regulatory inspections.

5.4. Corrective and Preventive Actions (CAPA)

1. If deviations are observed during concurrent validation, corrective actions must be initiated immediately. These actions should include:
   • Identifying the root cause of the deviation
   • Implementing corrective actions to address the identified issue
   • Recording corrective actions in the Corrective Action Log (Annexure-3)
   • Implementing preventive actions to avoid future occurrences of similar deviations
2. Any major deviations that affect product quality may require revalidation or re-testing of batches to ensure that the process is still capable of consistently producing products that meet specifications.

5.5. Final Review and Approval

1. Once the validation is completed, the process validation report and all related documentation must be reviewed by the QA team to ensure that all required steps were followed and that the process met all acceptance criteria.
2. The final validation report should be approved by the QA Manager and Manufacturing Manager. It should then be stored in the appropriate system for future audits and regulatory inspections.
3. If concurrent validation results in a positive outcome, the process will be considered validated for future production runs. If not, corrective or preventive actions must be implemented, and revalidation may be required.
