Oligonucleotide (oligo) therapies are rapidly advancing, driven by their applications in diagnostics, therapeutics, and personalized medicine. These therapies offer precise targeting capabilities for conditions ranging from rare genetic disorders to oncology and neurology, often at lower doses and with faster development timelines compared to traditional pharmaceuticals. However, the unique pharmacokinetic properties of oligos necessitate a reevaluation of drug metabolism and pharmacokinetics (DMPK) strategies, which must incorporate innovative platform approaches and robust in vitro models.
Understanding the DMPK characteristics of oligos is critical for ensuring their safety and efficacy, especially given their systemic administration and distinctive absorption, distribution, metabolism, and excretion profiles. Oligos are typically poorly absorbed when taken orally and require injection, leading to significant tissue accumulation and complex clearance mechanisms. These factors underscore the need for tailored DMPK strategies that can navigate the regulatory landscape while optimizing therapeutic outcomes.
As the field evolves, leveraging advanced in vitro models and monitoring metabolite profiles will be essential for predicting oligos’ behavior in vivo. By refining DMPK approaches, drug developers can mitigate risks associated with late-stage failures, ultimately enhancing the safety and effectiveness of oligonucleotide therapies for patients.
