Navigating the Complexities of mRNA Therapies Analysis: Challenges, Techniques, and Quality Assessment Strategies - Seguridad Mania.com - España y América Latina

The approval and widespread adoption of mRNA vaccines have revolutionized the field of immunization, offering rapid and scalable solutions to combat infectious diseases. This success has spurred significant research into using mRNA for other therapies, including cell therapies, protein production, genome editing and protein replacement. Ensuring the quality and safety of mRNAs in these therapies is crucial, requiring detailed impurity profiling and advanced analytical techniques. Incorporating mRNA into drug products presents significant manufacturing and analytical challenges, particularly in maintaining the integrity of mRNA drug substances and drug products. Rigorous release and stability testing are essential to ensuring these therapeutic products remain effective and safe throughout their lifecycle. Impurity profiling is an essential part of analytical characterization for mRNA-based products. During production, both process and product impurities can arise, such as truncated mRNA fragments, double-stranded RNA (dsRNA), and residual DNA from the plasmid template. These impurities can potentially impact the drug’s performance or trigger unintended immune responses. This presentation explores the types of impurities commonly found in mRNA-based products and the advanced analytical methods used to analyze them. We will also discuss the challenges faced, potential solutions, and the importance of analytical methods in supporting development programs and meeting expanding regulatory requirements. Continuous improvements in these analytical methods are crucial to address the evolving challenges in mRNA-based drug production and to maintain high standards of safety and effectiveness.
