What was the need?

The Challenge

A two year study by Dr Daniel Markl at the University of Strathclyde and GSK Materials Sciences was launched to build better methods to identify and characterise polymorph changes during tabletting processes. Improvements in characterisation methods that can distinguish polymorphs as well as the development of in situ methods that can capture transient changes have been made. These improvements will be used to optimise an approach to handling and characterising systems that undergo phase transformations when compressed.

What did we do?

The Solution

To enhance the characterization of polymorphic forms of active pharmaceutical ingredients (APIs), developing a structured workflow is essential. This workflow can address the challenges associated with polymorphism assessment, improving the efficiency and reliability of the process.

1. Integrated Characterization Techniques

Implementing an integrated approach that combines multiple characterization techniques—such as X-ray powder diffraction (XRPD), differential scanning calorimetry (DSC), and Raman spectroscopy—can significantly improve the accuracy of polymorphic identification. Each technique provides unique insights into the physical and chemical properties of polymorphs, allowing for comprehensive analysis and cross-validation of results.

2. Standardized Operating Procedures

Establishing standardized operating procedures (SOPs) for sample preparation, data acquisition, and analysis is crucial for enhancing reproducibility. By minimizing variability in handling and testing, SOPs ensure consistent results across different laboratories, which is essential for regulatory compliance.

3. Interdisciplinary Collaboration

Encouraging collaboration among chemists, materials scientists, and regulatory experts fosters a holistic approach to polymorphic characterization. This interdisciplinary teamwork ensures that the workflow addresses all relevant aspects of polymorphism, from scientific understanding to regulatory compliance.

By adopting these strategies, pharmaceutical developers can improve the characterization of polymorphic forms, leading to better drug formulations, enhanced therapeutic efficacy, and ultimately, improved patient outcomes. This structured workflow not only addresses current challenges but also paves the way for innovation in pharmaceutical development.

The Impacts and Benefits

Impact for the Company

Compression-induced polymorphic transformations in active pharmaceutical ingredients (APIs) prevent consistent product quality and efficient manufacturing processes. This is due to the effect of multiple polymorphs in the final drug product. Polymorphism, where an API can exist in multiple crystalline forms, can significantly impact drug performance by altering solubility, bioavailability, and stability in a drug product. Greater control of the polymorphic form during tabletting processes and better characterisation techniques will lead to more efficient scale-up from R&D to full-scale manufacturing. Overall better management of potential polymorphic transformations will improve product consistency, reduces costs, speed up development, and ensure regulatory compliance, ultimately providing a competitive advantage to the company in the pharmaceutical market.

 

Impacts for the Academic Team 

Developing a workflow to manage compression-induced polymorphic transformations of APIs greatly benefits academic research teams by improving efficiency, data quality, and collaboration. A structured approach streamlines experimentation, allowing researchers to follow systematic protocols that reduce trial-and-error efforts, resulting in more reliable, reproducible data. Integrating advanced analytical tools like X-ray diffraction (XRD) and Raman spectroscopy into the workflow enables precise detection and analysis of polymorphic changes, providing deeper insights into how factors like pressure and temperature affect API behaviour. This enhanced data collection supports more accurate research findings, which are crucial for advancing pharmaceutical science. Additionally, a well-documented workflow fosters collaboration by making it easier to share methods and results with other researchers and industry partners, opening opportunities for interdisciplinary projects and funding. It also serves as a valuable educational tool, teaching students and early-career researchers best practices in experimental design and process control. Ultimately, a structured workflow enhances research productivity, facilitates collaboration, and increases the potential for securing grants and high-impact publications.

 

Impacts for the KTP Associate 

Developing a workflow significantly enhances an associate's learning and professional development by providing a structured framework for conducting research. This structured approach helps associates grasp complex concepts and methodologies more easily. As associate engages with the workflow, they acquire practical skills in various techniques and tools, fostering hands-on experience essential for their future careers. A defined workflow encourages critical thinking and problem-solving, enabling the KTP associate to anticipate challenges and make informed decisions based on data. It also emphasizes the importance of documentation and clear communication of methods and findings, which are crucial for reproducibility and collaboration. Moreover, working within a workflow facilitates interdisciplinary collaboration, broadening associates’ knowledge and enhancing teamwork skills. Regular checkpoints for evaluation and feedback promote a culture of continuous improvement, encouraging associates to refine their skills over time. Ultimately, developing competencies through a structured workflow positions associates for greater career advancement opportunities and prepares them for future challenges in their professional journeys.
