Definition: Combination products are therapeutic and diagnostic products that combine drugs, devices, and/or biological products.
- Examples: Drug-eluting stents, prefilled syringes with drugs, and drug-device combination products.
Unique Challenges in Pharmacovigilance for Combination Products
1. Complexity of Safety Profiles
- Interaction Effects: Potential interactions between drug components and device materials.
- Device Failure: Safety concerns related to device malfunction or failure affecting drug delivery.
2. Regulatory Classification
- Classification: Determined by primary mode of action (drug or device).
- Regulatory Oversight: Oversight by multiple regulatory agencies (e.g., FDA's Center for Drug Evaluation and Research (CDER) and Center for Devices and Radiological Health (CDRH)).
3. Safety Data Collection and Reporting
- Integrated Safety Reporting: Need for integrated safety reporting systems to capture both drug-related and device-related adverse events (AEs).
- Device Malfunction Reporting: Specific reporting requirements for device malfunctions impacting drug delivery or safety.
4. Risk Assessment and Management
- Comprehensive Risk Assessment: Evaluation of both drug and device components for potential risks.
- Combined Risk Mitigation Strategies: Integration of drug-related and device-related risk management plans (RMPs).
5. Post-Marketing Surveillance
- Surveillance Systems: Utilization of pharmacovigilance and medical device vigilance systems to monitor post-marketing safety.
- Signal Detection: Methods to detect signals related to both drug and device components.
6. Regulatory Reporting Requirements
- Adverse Event Reporting: Specific requirements for reporting AEs and serious adverse events (SAEs) related to both drug and device components.
- Periodic Safety Update Reports (PSURs): Integration of safety data from both components in periodic safety reporting.
7. Manufacturing and Quality Control
- Quality Systems: Compliance with Good Manufacturing Practices (GMP) for both drug and device components.
- Quality Control: Ensuring consistency and reliability in manufacturing processes impacting product safety.
8. Labeling and Instructions for Use
- Clear Instructions: Adequate labeling to guide healthcare professionals and patients on the safe use of combination products.
- Risk Communication: Effective communication of combined risks and precautions associated with both drug and device components.
Case Examples and Practical Considerations
- Drug-Eluting Stents: Monitoring for both drug-related AEs (e.g., systemic effects) and device-related issues (e.g., stent fracture).
- Prefilled Syringes: Ensuring proper administration techniques and monitoring for device-related injection site reactions.
- Infusion Pumps with Drugs: Managing infusion-related complications and drug-specific adverse reactions.
Future Directions and Emerging Trends
- Advancements in Technology: Integration of advanced technologies (e.g., smart devices, digital health solutions) for enhanced safety monitoring.
- Regulatory Harmonization: Continued efforts to harmonize global regulatory requirements for combination products.
- Patient-Centric Approaches: Incorporation of patient-reported outcomes and patient engagement strategies in safety monitoring.
