Procedure for Preparing Stability Data in Accordance with QbD Principles
1) Purpose
The purpose of this SOP is to define a procedure for preparing stability data in compliance with the US FDA’s Quality by Design (QbD) approach. This ensures that stability data supports product quality throughout its lifecycle by systematically understanding and controlling variability.
2) Scope
This SOP applies to all personnel involved in the preparation, analysis, and submission of stability data as part of the QbD approach, including quality control, product development, and regulatory affairs teams.
3) Responsibilities
Product Development Team: Responsible for designing the stability study in alignment with QbD principles.
Stability Study Team: Responsible for executing stability studies according to the QbD-based protocol.
Regulatory Affairs Team: Responsible for ensuring that stability data complies with QbD requirements and is ready for submission to the FDA.
4) Procedure
4.1 Design of Experiment (DoE)
4.1.1 Develop
4.1.2 Define appropriate storage conditions and testing intervals based on QbD principles.
4.2 Sample Preparation and Storage
4.2.1 Prepare samples according to the approved QbD-based protocol.
4.2.2 Store samples under conditions specified by the protocol.
4.3 Conducting Stability Tests
4.3.1 Perform stability tests at all defined intervals to evaluate CQAs and CPPs.
4.3.2 Document all data accurately, ensuring alignment with QbD principles.
4.4 Data Analysis and Reporting
4.4.1 Analyze stability data to confirm product quality over its intended shelf life.
4.4.2 Prepare a comprehensive stability report for submission to the FDA.
