Area of Science:

  • Pharmaceutical Sciences
  • Drug Delivery Systems
  • Clinical Pharmacology

Background:

  • Increasing number of new drugs exhibit challenging pharmaceutical (e.g., solubility) and biopharmaceutical (e.g., permeability) properties.
  • Pharmaceutical companies increasingly rely on human absorption studies for drug development guidance.
  • Early clinical development necessitates efficient and non-invasive methods for drug administration.

Purpose of the Study:

  • To introduce and evaluate the Enterion capsule as a novel tool for drug delivery in human absorption studies.
  • To demonstrate the capsule's capability in delivering various drug formulations to specific gastrointestinal sites.
  • To facilitate early-stage clinical development of drugs with challenging properties.

Main Methods:

  • Utilized engineering-based capsules for non-invasive drug delivery within the human gut.
  • Employed the Enterion capsule for targeted delivery of diverse drug formulations (solution, powder, granulate).
  • Conducted human absorption studies to assess drug delivery efficiency and site-specificity.

    • Main Results:

    • The Enterion capsule successfully delivered various drug formulations to targeted regions of the human gut.
    • Demonstrated ease and efficiency in drug delivery across different formulation types.
    • Provided a viable 'route map' for the development of drugs with challenging properties.

    Conclusions:

    • The Enterion capsule represents a significant advancement in non-invasive drug delivery for human absorption studies.
    • This technology aids in overcoming formulation and biopharmaceutical challenges in early drug development.
    • Facilitates efficient gastrointestinal drug delivery, supporting the progression of new pharmaceutical entities.
