Post-marketing Research

Post-marketing research encompasses a wide range of studies conducted after product approval, including safety surveillance, real-world evidence generation, and optimization of clinical use. It serves as both an extension of pre-marketing research and a key source of data for regulatory decision-making, label expansion, and market access.

As global regulatory authorities such as the U.S. FDA and the European Medicines Agency increasingly emphasize post-approval commitments, post-marketing research has become an essential component of lifecycle management. It supports continuous benefit-risk evaluation, regulatory compliance, label expansion, and evidence generation for market access decisions.

Regulatory Framework & Compliance Requirements

Post-marketing research is closely governed by global regulatory expectations that ensure ongoing safety and effectiveness of approved products.

Key regulatory considerations include:

• Post-approval study commitments required by regulatory authorities
• Pharmacovigilance obligations for continuous safety monitoring
• Real-world evidence requirements for regulatory decision-making
• Global compliance with FDA, EMA, NMPA, and PMDA guidelines
• Risk management and post-authorization safety surveillance requirements

These frameworks ensure that marketed products continue to meet safety and efficacy standards throughout their lifecycle.

Real-World Data & Analytical Capabilities

Why Post-Marketing Research Matters

Post-marketing research is an essential and irreplaceable component of the drug lifecycle. It enables:

• Continuous safety monitoring and risk mitigation
• Expansion into new indications and populations
• Optimization of treatment strategies
• Generation of real-world evidence for decision-making
• Strengthening of market access and product competitiveness

Post-marketing research is not just a regulatory requirement-it is a strategic opportunity to continuously validate, differentiate, and expand the value of your product.
