  Purpose

The objective of this Phase I trial is to demonstrate the bioequivalence of two capsules of dabigatran etexilate made from two different drug product batches.

The reference batch is dabigatran etexilate hard capsules 150 mg using the currently approved capsule shell (Qualicaps). The test batch is dabigatran etexilate 150 mg hard capsules using a new capsule shell (Capsugel). The test batch is the drug product intended for future commercial use.


Condition Intervention Phase
Healthy Drug: Dabigatran etexilate Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Bioequivalence of Two Different Capsule Types of 150 mg Dabigatran Etexilate Made From Two Different Drug Product Batches, Following Oral Administration in Healthy Male and Female Volunteers (Open-label, Randomised, Single Dose, Replicate Design in a Two Treatments, Four Periods Crossover Phase I Study)

Primary Outcome Measures:
  • Area Under the Curve 0 to tz (AUC0-tz) of Total Dabigatran [ Time Frame: 60 hours ]
    Area under the concentration-time curve of total dabigatran in plasma from time 0 to the time of the last quantifiable data point, adjusted for treatment, period and sequence (all fixed effects), and random subject effect.

  • Maximum Measured Concentration (Cmax) of Total Dabigatran in Plasma [ Time Frame: 60 hours ]
    Adjusted for treatment, period and sequence (all fixed effects), and random subject effect.


Secondary Outcome Measures:
  • Area Under the Curve 0 to Infinity (AUC0-∞) of Total Dabigatran. [ Time Frame: 60 hours ]
    Area under the concentration-time curve of total dabigatran in plasma over the time interval from 0 extrapolated to infinity. Adjusted for treatment, period and sequence (all fixed effects), and random subject effect.

  • AUC0-tz of Free Dabigatran. [ Time Frame: 60 hours ]
    Area under the concentration-time curve of free dabigatran in plasma from time 0 to the time of the last quantifiable data point. Adjusted for treatment, period and sequence (all fixed effects), and random subject effect.

  • Cmax of Free Dabigatran in Plasma. [ Time Frame: 60 hours ]
    Adjusted for treatment, period and sequence (all fixed effects), and random subject effect.

  • AUC0-∞ of Free Dabigatran. [ Time Frame: 60 hours ]
    Area under the concentration-time curve of free dabigatran in plasma over the time interval from 0 extrapolated to infinity. Adjusted for treatment, period and sequence (all fixed effects), and random subject effect.
