Post approval support

Maintaining Compliance and Performance After Approval

We help you maintain validated processes, strengthen control strategies, and adapt efficiently to post-approval changes, ensuring continued compliance and product quality throughout the commercial lifecycle.

Post Approval Support
Quick filter:

Approval is not the finish line, it’s the start of continual oversight. Once your process is commercialised, every change, deviation, and improvement must be scientifically justified and regulatory aligned.

We support you in managing that complexity. We help you sustain process robustness, implement improvements safely, and document changes with the same rigour that earned approval in the first place.

From lifecycle management to change control and ongoing validation, we ensure your process, data, and documentation remain compliant, efficient, and future-ready.

How We Support You
Maintain and Verify Process Performance
Implement continued process verification (CPV) and statistical trending to ensure ongoing control.
Support Post-Approval Changes
Provide data packages, comparability studies, and risk assessments for regulatory submissions or site transfers.
Optimise Efficiency and Sustainability
Identify opportunities for cost reduction, waste minimisation, and improved process yield without compromising compliance.
Strengthen Analytical and Quality Systems
Validate updated methods, manage specification changes, and ensure analytical traceability.
Ensure Inspection and Audit Readiness
Maintain complete, defensible documentation aligned with global GMP and regulatory expectations.
