Factors Influencing ADME Properties of Therapeutic Antisense Oligonucleotides : Physicochemical Characteristics and Beyond
Copyright© Bentham Science Publishers; For any queries, please email at epubbenthamscience.net..
Therapeutic antisense oligonucleotides (ASOs) represent a diverse array of chemically modified singlestranded deoxyribonucleotides that work complementarily to affect their mRNA targets. They vastly differ from conventional small molecules. These newly developed therapeutic ASOs possess unique absorption, distribution, metabolism, and excretion (ADME) processes that ultimately determine their pharmacokinetic, efficacy and safety profiles. The ADME properties of ASOs and associated key factors have not been fully investigated. Therefore, thorough characterization and in-depth study of their ADME properties are critical to support drug discovery and development processes for safe and effective therapeutic ASOs. In this review, we discussed the main factors affecting the ADME characteristics of these novels and evolving therapies. The major changes to ASO backbone and sugar chemistry, conjugation approaches, sites and routes of administration, etc., are the principal determinants of ADME and PK profiles that consequentially impact their efficacy and safety profiles. In addition, species difference and DDI considerations are important in understanding ADME profile and PK translatability but are less studied for ASOs. We, therefore, have summarized these aspects based on current knowledge and provided discussions in this review. We also give an overview of the current tools, technologies, and approaches available to investigate key factors that influence the ADME of ASO drugs and provide future perspectives and knowledge gap analysis.
