Post-approval actions include:

• Adverse Event Reporting: Implement mechanisms for monitoring and reporting adverse events to the FDA as part of your pharmacovigilance program.
• Manufacturing Changes: Any changes to the manufacturing process or product formulation must be submitted for approval as supplements to the original application.
• Periodic Safety Update Reports (PSURs): Prepare PSURs to summarize the benefit-risk profile and ensure continued market access.

Engaging in continuous dialogue with regulatory agencies post-approval will help manage short-term and long-term compliance expectations while enabling strategic decisions based on regulatory changes, market fluctuations, or evolving scientific data.

Documentation expectations will include all safety communications, product performance data, and modifications to your quality management systems that adhere to ongoing GxP standards.
