Purpose

The purpose of this SOP is to establish standardized workflows for the collection, processing, shipment, storage, and analysis of immunogenicity

samples in clinical trials. It also outlines requirements for specialty laboratories performing immunogenicity assays, ensuring accuracy, traceability, and regulatory compliance.

Scope

This SOP applies to sponsors, investigators, CROs, laboratory staff, couriers, and specialty immunology laboratories engaged in immunogenicity sample workflows for clinical trials. It covers collection, labeling, chain of custody, assay performance, reporting, and archiving of data.

Responsibilities

Sponsor: Oversees immunogenicity workflows and ensures laboratory qualification.
Investigator: Ensures accurate collection, labeling, and shipment of samples.
Site Staff: Responsible for proper handling, storage, and timely shipment of samples.
Specialty Laboratories: Perform validated assays and report results accurately.
CRO: Monitors compliance with sample workflows and laboratory SOPs.
QA: Audits specialty labs and ensures inspection readiness.

Accountability

The Sponsor’s Immunogenicity Lead is accountable for oversight of immunogenicity workflows. Specialty laboratory directors are accountable for assay performance and reporting accuracy.

Procedure

1. Sample Collection
1.1 Collect blood or biological samples per protocol.
1.2 Label with subject ID, date/time, and trial identifier.
1.3 Record in Immunogenicity Sample Collection Log (Annexure-1).

2. Sample Processing
2.1 Process within specified timeframe (centrifugation, serum separation).
2.2 Store aliquots as required (-80°C or cryogenic storage).
2.3 Record in Sample Processing Log (Annexure-2).

3. Storage
3.1 Maintain validated storage conditions.
3.2 Monitor and record temperatures continuously.
3.3 Record in Sample Storage Log (Annexure-3).

4. Shipment
4.1 Ship samples to specialty labs in validated containers with dry ice or cold packs.
4.2 Record chain of custody in Shipment Log (Annexure-4).

5. Specialty Lab Requirements
5.1 Labs must be GCLP/GLP compliant and validated for immunogenicity assays.
5.2 Perform assay validation prior to clinical sample testing.
5.3 Maintain Accreditation Certificates (Annexure-5).

6. Assay Performance
6.1 Use validated assays such as ELISA, neutralizing antibody assays, or cellular assays.
6.2 Maintain detailed Assay Performance Log (Annexure-6).

7. Data Reporting
7.1 Report results in standardized electronic format.
7.2 Ensure secure transmission to sponsor.
7.3 Record reporting in Data Reporting Log (Annexure-7).

8. Archiving
8.1 Archive raw data, assay reports, and chain of custody records in TMF and ISF.
8.2 Retain per global regulatory timelines.
