Standard Operating Procedure for the Validation of Cryo/Cold Storage Equipment

Purpose: This SOP outlines the validation process for Cryo/Cold Storage equipment used in the storage of NDDS intermediates, Drug Substance (DS), and Drug Product (DP) within the Warehouse/QA area.

Scope: This procedure applies to all Cryo/Cold Storage equipment operating at temperatures of 2–8°C, -20°C, and -80°C, classified as critical with a direct impact on product quality.

Definitions:

• NDDS: Novel Drug Delivery Systems
• DS: Drug Substance
• DP: Drug Product
• CSV: Computerized System Validation
• URS: User Requirements Specification

Roles:

• Validation Team: Responsible for the execution of validation protocols.
• Quality Assurance: Oversees compliance with regulatory requirements.
• Equipment Owner: Ensures equipment maintenance and operation.

Lifecycle Procedure:

• Design Qualification (DQ): Verify that the equipment meets the user requirements.
• Installation Qualification (IQ): Confirm the equipment is installed correctly and according to specifications.
• Operational Qualification (OQ): Ensure the equipment operates within specified limits.
• Performance Qualification (PQ): Validate the equipment’s performance under actual operating conditions.

Good Documentation Practices (GDP) Controls:

• All validation documents must be completed in real-time.
• Corrections must be initialed and dated.
• Documents should be reviewed and approved by authorized personnel.

Acceptance Criteria Governance:

• Acceptance criteria will be defined in the User Requirements Specification (URS) and will adhere to Annex 11 and Annex 15 guidelines.
• All criteria must be met before proceeding to the next validation phase.

Calibration and Preventive Maintenance (PM) Governance:

• Calibration of equipment must be performed according to the manufacturer’s specifications.
• Preventive maintenance schedules must be established and adhered to.

Change Control Triggers:

• Any modification to the equipment or its operating parameters must initiate a change control process.
• Changes in storage requirements or product specifications require revalidation.

Revalidation Triggers and Periodic Review:

• Revalidation is required annually.
• Triggers include significant changes in equipment, processes, or product formulations.
