Tip:
Maintain strong data quality and validation controls to ensure that electronically submitted ICSRs are complete, accurate, and compliant with applicable requirements.
3. ICH E2C(R2) – Periodic Benefit-Risk Evaluation Report
ICH E2C(R2) focuses on the Periodic Benefit-Risk Evaluation Report (PBRER).
The PBRER provides a structured framework for periodically evaluating the benefits and risks of a medicinal product after authorization.
Rather than focusing only on individual safety cases, the PBRER brings together broader safety information to support an overall assessment of the product’s benefit-risk balance.
The assessment may consider:
- New safety information
- Changes in exposure
- Important identified risks
- Important potential risks
- New safety signals
- Regulatory actions
- Benefit information
- Overall benefit-risk evaluation
Tip:
Maintain a well-organized safety data collection and signal management process so information required for periodic benefit-risk assessments can be identified efficiently.
4. ICH E2D – Post-Approval Safety Data Management
ICH E2D provides important principles for post-approval safety data management.
After a medicine reaches the market, safety information can come from numerous sources, including healthcare professionals, patients, literature, regulatory authorities, partners, and other reporting channels.
Organizations need effective processes for receiving, evaluating, documenting, and processing these reports.
The guideline supports consistent approaches to post-approval safety information and helps organizations establish appropriate case management processes.
Tip:
Create clear procedures for safety information intake, case validation, processing, follow-up, assessment, and reporting.
5. ICH E2E – Pharmacovigilance Planning
ICH E2E focuses on pharmacovigilance planning and provides a framework for identifying important risks and developing appropriate safety monitoring strategies.
Pharmacovigilance planning is particularly important when organizations need to determine how potential safety concerns should be monitored after a product enters the market.
A strong pharmacovigilance plan can include:
- Safety specifications
- Important identified risks
- Important potential risks
- Missing information
- Routine pharmacovigilance activities
- Additional pharmacovigilance activities
- Risk minimization considerations
Tip:
Use a risk-based approach when developing pharmacovigilance plans and ensure that monitoring activities are aligned with the product’s safety profile.
6. ICH E2F – Development Safety Update Report
The Development Safety Update Report (DSUR) provides a standardized framework for periodic reporting of safety information during clinical development.
The DSUR brings together relevant clinical trial safety information and helps sponsors provide regulators with an integrated review of the evolving safety profile of an investigational product.
The report can support evaluation of:
- Serious adverse events
- Safety signals
- New safety information
- Changes in the safety profile
- Ongoing clinical trials
- Cumulative safety data
Tip:
Maintain centralized and well-controlled clinical safety data to support accurate and timely preparation of DSURs.
7. ICH E6 – Good Clinical Practice
ICH E6 is widely recognized for its focus on Good Clinical Practice (GCP).
GCP establishes important principles for the design, conduct, recording, and reporting of clinical trials involving human participants.
From a pharmacovigilance perspective, GCP is important because reliable safety information depends on appropriate clinical trial processes and accurate documentation.
Key areas include:
- Participant safety
- Informed consent
- Investigator responsibilities
- Sponsor responsibilities
- Safety reporting
- Data integrity
- Trial documentation
- Quality management
Tip:
Ensure that clinical safety processes are integrated with overall GCP quality systems and that safety information is captured, reviewed, and reported appropriately.
8. ICH E19 – Optimisation of Safety Data Collection
ICH E19 addresses the optimization of safety data collection in specific late-stage pre-approval clinical trials.
The objective is to support more efficient safety data collection while maintaining appropriate protection of trial participants.
For suitable situations, organizations may consider approaches that focus safety data collection on information that is most relevant to the ongoing assessment of the investigational product.
This can help reduce unnecessary data collection while maintaining appropriate safety oversight.
Tip:
Use a scientifically justified and risk-based approach when considering optimization of safety data collection.
9. ICH M1 – MedDRA Terminology
Medical Dictionary for Regulatory Activities (MedDRA) terminology is an important component of modern pharmacovigilance.
MedDRA provides standardized medical terminology that supports consistent coding and analysis of medical information.
It can be used across various stages of the product lifecycle, including:
- Clinical trials
- Pharmacovigilance
- Regulatory submissions
- Safety databases
