Design of Experiments Approach for Process Validation

This white paper discusses the Design of Experiments (DoE) approach utilized by Cambrex for process validation in active pharmaceutical ingredient (API) production. It outlines the significance of process validation as a critical step in preparing for commercial API production, emphasizing the need for comprehensive knowledge and data regarding the manufacturing process. The document details a systematic methodology that Cambrex applied to enhance efficiency and reduce costs during the validation phase. It highlights the application of statistical methodologies to interpret data and manage experiments effectively, thereby minimizing timelines and expenses. The paper also describes specific trials conducted to evaluate the reaction conversions and yields of various starting materials, demonstrating how the approach led to robust operating parameters suitable for commercial scale validation. Furthermore, it emphasizes the importance of rigorous control over reaction conditions and the identification of impurities to ensure compliance with quality standards. Overall, the document presents a structured framework for optimizing API manufacturing processes.
