Standard Operating Procedure for QT/QTc (ICH E14) Signal Management

Purpose

The purpose of this SOP is to define processes for managing QT/QTc signals in clinical trials in alignment with ICH E14. QT prolongation poses significant cardiac risks, and proper signal detection and management are essential for ensuring subject safety and meeting regulatory obligations.

Scope

This SOP applies to sponsors, CROs, investigators, pharmacovigilance (PV) staff, data managers, and QA staff engaged in cardiac safety monitoring during clinical trials. It covers ECG data collection, analysis, signal management, regulatory submissions, and archiving.

Responsibilities

• Sponsor: Ensures trial protocols include cardiac safety monitoring per ICH E14.
• CRO: Coordinates ECG collection, transmission, and data management.
• Investigator: Performs ECGs and documents QT/QTc abnormalities.
• PV Department: Monitors for cardiac signals and reports SAEs to regulators.
• QA: Audits ECG and cardiac safety processes for compliance.

Accountability

The Sponsor’s Head of Pharmacovigilance and Biostatistics is accountable for ensuring adherence to ICH E14 cardiac safety requirements and proper QT/QTc signal management.

Procedure

1. ECG Data Collection
1.1 Collect baseline and follow-up ECGs per protocol.
1.2 Use standardized equipment validated for QT/QTc assessment.
1.3 Record in ECG Collection Log (Annexure-1).

2. Data Handling and Analysis
2.1 Transfer ECG data to central lab or validated system.
2.2 Biostatisticians analyze QT/QTc intervals using validated methods.
2.3 Document in ECG Data Handling Log (Annexure-2).

3. Signal Detection
3.1 Identify potential QT prolongation signals (e.g., >450ms in males, >470ms in females).
3.2 Escalate findings to PV and Data Safety Monitoring Board (DSMB).
3.3 Record in Signal Detection Log (Annexure-3).

4. Regulatory Reporting
4.1 Report QT/QTc-related SAEs and SUSARs to regulators.
4.2 Submit safety updates in DSUR and CSR.
4.3 Document in Regulatory Reporting Log (Annexure-4).

5. Risk Mitigation
5.1 Implement dose adjustment, treatment discontinuation, or subject withdrawal as required.
5.2 Ensure subject safety measures are recorded in Risk Mitigation Log (Annexure-5).

6. Archiving
6.1 Archive ECG data, analysis reports, and regulatory submissions in TMF.
6.2 Record archiving details in ECG Archiving Log (Annexure-6).
