By identifying gaps before inspectors do.
Applying controls based on the severity and probability of data errors. 🏗️ Data Governance Framework
PDA Technical Report 90 is more than a technical document—it is a strategic tool for operational excellence. By adopting its framework, pharmaceutical manufacturers gain:
Using periodic audits to refine data handling processes. The Role of Organizational Culture pda technical report 90
Published by the Parenteral Drug Association (PDA), TR 90 represents a paradigm shift in how the industry approaches aseptic process validation (APV). Titled “Aseptic Process Validation: A Risk-Based Approach,” this document provides a framework for moving away from rigid revalidation timelines toward a dynamic, scientifically justified lifecycle approach.
To understand TR 90’s importance, one must look at the 2022 revision of the EU GMP Annex 1: “Manufacture of Sterile Medicinal Products.” Annex 1 explicitly requires manufacturers to implement a . However, Annex 1 defines what a CCS is, but not how to build one.
Building confidence with stakeholders that all test results and manufacturing records are authentic. If you'd like to dive deeper into this, let me know: By identifying gaps before inspectors do
The report organizes the CCS into four primary life-cycle phases:
Industry experts predict that by 2027, of cleanrooms will be used to simulate contamination events, and those simulations will be validated against the criteria set forth in TR 90.
TR 90 categorizes changes and events that serve as triggers, such as: To understand TR 90’s importance, one must look
To understand the impact of TR 90, one must look at its three foundational pillars: Risk-Based Decision Making, the Validation Lifecycle, and Change Management.
Establishing consistent workflows for data entry and review.
| Pillar | Key Elements Covered in TR-90 | | :--- | :--- | | | Cleanroom classification, HVAC design, airflow visualization (smoke studies), material flow, equipment sterilization. | | 2. Utilities | Water systems (WFI, Purified Water), clean steam, compressed gases (microbial and particulate control). | | 3. Personnel | Gowning qualification, human behavior training, hygiene, unidirectional flow discipline, intervention risks. | | 4. Materials & Components | Raw material bioburden control, container closure integrity, sterilization methods, transfer processes. | | 5. Process & Product | Hold times, filling operations, lyophilization, aseptic connections, single-use systems validation. | | 6. Monitoring & Data | Environmental monitoring (viable/non-viable), rapid microbiological methods, trend analysis, alert/action limits. |
A unique strength of TR 90 is its focus on the "human element." It suggests that even the best technical controls will fail if the corporate culture encourages shortcuts.
