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

“Unveiling the Untold: Innovatively Reliable HPLC Methods for Drug Analysis Ensuring Stability and Quality Assurance”

4.1.1 Develop a stability study protocol using a Design of Experiment (DoE) approach to identify critical quality attributes (CQAs) and critical process parameters (CPPs).

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
