Abstract
Purpose: This study aimed to characterize the physicochemical stability of mRNA-lipid nanoparticle (LNP) influenza vaccine candidates under various environmental stressors using forced degradation studies (FDSs) and to correlate these changes with in vitro protein expression.
Methods: FDSs were conducted to evaluate the effects of temperature, oxidation, hydrolysis, and agitation on mRNA-LNP formulations. Comprehensive analytical techniques were employed to monitor the purity and integrity of mRNA, mRNA encapsulation efficiency, in vitro expression, LNP components, and particle characteristics.
Results: The study revealed hydrolysis-induced degradation of distearoylphosphatidylcholine (DSPC), a key LNP component, and rapid oxidation-induced mRNA degradation within the LNPs. Agitation was found to increase LNP size, decrease mRNA encapsulation efficiency, and subsequently reduce in vitro protein expression.
Conclusions: We established robust analytical methods to monitor the quality and stability of mRNA-LNP products. These findings provide a critical foundation for integrated analytical strategies to enhance the stability of mRNA-LNP therapeutics and vaccines during storage, transport, and clinical application.
期刊介绍:
Pharmaceutical Research, an official journal of the American Association of Pharmaceutical Scientists, is committed to publishing novel research that is mechanism-based, hypothesis-driven and addresses significant issues in drug discovery, development and regulation. Current areas of interest include, but are not limited to:
-(pre)formulation engineering and processing-
computational biopharmaceutics-
drug delivery and targeting-
molecular biopharmaceutics and drug disposition (including cellular and molecular pharmacology)-
pharmacokinetics, pharmacodynamics and pharmacogenetics.
Research may involve nonclinical and clinical studies, and utilize both in vitro and in vivo approaches. Studies on small drug molecules, pharmaceutical solid materials (including biomaterials, polymers and nanoparticles) biotechnology products (including genes, peptides, proteins and vaccines), and genetically engineered cells are welcome.
