Drug candidates causing pharmacokinetic drug-drug interactions often fail commercially. Rapid, cost-effective screens now exist to evaluate this potential, with ongoing progress in increasing their throughput for drug development.
Area of Science:
- Pharmacology
- Drug Development
- Biochemistry
Background:
- Pharmacokinetic drug-drug interactions (pDDIs) are a significant cause of late-stage drug candidate attrition.
- Early identification of pDDIs is crucial for successful drug development and commercialization.
- Existing screening methods can be time-consuming and costly, hindering early assessment.
Purpose of the Study:
- To review experimental designs for mechanism-based screening of pDDIs.
- To highlight recent advancements in increasing the throughput of these screens.
- To provide an overview of tools for predicting drug-drug interaction potential.
Main Methods:
- Review of literature on in vitro and in silico methods for pDDI screening.
- Analysis of experimental designs focusing on enzyme phenotyping and inhibition assays.
- Discussion of high-throughput screening (HTS) strategies and automation.
Main Results:
- Rapid, cost-effective, mechanism-based screening assays are available.
- Significant progress has been made in enhancing the throughput of these assays.
- These advancements facilitate earlier and more efficient evaluation of pDDI potential.
Conclusions:
- High-throughput screening for pDDIs is essential for de-risking drug candidates.
- Improved screening methodologies accelerate the drug development process.
- The review provides a valuable resource for researchers aiming to mitigate pDDI risks.
