Criteria for Evaluation:
Clinical
Pharmacology:
The following pharmacokinetic parameters of total dabigatran (free
dabigatran and conjugates cleaved by alkaline hydrolysis) were analysed as
primary endpoints: AUCτ, ss and Cmax, ss. As secondary endpoints AUCτ, ss and
Cmax, ss of free dabigatran were analysed.
Safety/Other:
The evaluation of safety was based on monitoring for adverse events (AEs),
clinical laboratory assessments (haematology, clinical chemistry, and
urinalysis), vital signs, 12-lead electrocardiograms (ECG), and physical
examination.
Furthermore, the assessment of palatability and acceptability, which was a
secondary endpoint, was assessed by 2 multiple choice verbal questions.
Statistical Methods:
To assess relative bioavailability, the ratios of the geometric means (each test
treatment compared with the reference treatment) for the primary and
secondary pharmacokinetic endpoints were calculated. Additionally, their 2sided 90% confidence intervals (CIs) were calculated. The statistical model
used was an analysis of variance (ANOVA) on the logarithmic scale
including effects for ‘sequence’, ‘subjects within sequences’, ‘period’ and
‘treatment’. CIs were calculated based on the residual error from ANOVA.
Descriptive statistics were calculated for all endpoints and safety assessments.
An interim analysis was not planned.
SUMMARY - CONCLUSIONS:
Trial Subjects and
Compliance with
Trial Protocol:
All 54 entered subjects completed the treatment periods and observation
times as planned. There were no important protocol violations. One subject
discontinued trial medication prematurely due to an AE, which was not
considered as drug-related by the investigator, when being treated with
dabigatran etexilate as hard capsule (R). This subject did not receive the last
planned dose. The mean age of the subjects was 36.2 years, ranging from 20
to 53 years. All subjects were male and White. Of the 54 subjects entered,
53 subjects were administered a total dose of 750 mg dabigatran etexilate
during each treatment period as planned. One subject received 600 mg
dabigatran etexilate while being treated with dabigatran etexilate as hard
capsule (R). This subject received the planned dose in both other treatments
(T1 and T2).

This relative bioavailability trial was performed to compare dabigatran
Clinical
Pharmacology Results: plasma concentrations following administration of different dosage
formulations. Inter-individual variability for Cmax,ss and AUCτ,ss values
differed between formulations, with low variability for both test formulations
and moderately high variability for the reference hard capsule formulation.
The majority of subjects had lower Cmax,ss and AUCτ,ss values for the hard
capsule formulation than for either of the test formulations. As such, the
results showed higher bioavailability of pellets on food and granules resolved
in reconstitution solution test formulations compared to the reference hard
capsule formulation. It should be noted that individuals with high peak or
average exposure after intake of dabigatran etexilate as hard capsule (R) did
not show further exposure increase with the other formulations. Trough
concentrations were similar between the 3 formulations.
Statistical analysis for the primary and secondary endpoints provided the
following results:

Safety Results/Other
Results (continued):
(11.1%), gastrointestinal disorders (7.4%), and vascular disorders (5.6%). The
investigator classified AEs of 7 subjects (13.0%) as related to study
medication. All AEs were of mild or moderate intensity and except for 2
(paraesthesia of the fingers of mild intensity which was considered as not
drug-related by the investigator, and haematoma of mild intensity which was
considered as drug-related by the investigator), they had all resolved at the
end of the trial.
There were no clinically relevant findings with respect to laboratory
parameters, vital signs, physical examination, and 12-lead ECGs.
Multiple choice verbal questions on palatability and acceptability were
answered by 53 subjects for dabigatran etexilate as pellets on food (T1) and
by 53 subjects for dabigatran etexilate as granules resolved in reconstitution
solution (T2). Palatability and acceptability of dabigatran etexilate pellets on
food (T1) appeared to be better on a 5 category scale than that of dabigatran
etexilate as granules resolved in reconstitution solution (T2), although the
95% CIs showed overlap.
Conclusions:
Dabigatran etexilate as pellets on food (T1) and dabigatran etexilate as
granules resolved in reconstitution solution (T2) test formulations resulted in
a higher average relative bioavailability compared with the dabigatran
etexilate as hard capsule (R) reference formulation. However, individual
Cmax,ss and AUCτ,ss values observed for the 3 formulations were within the
range of exposure seen with previous dabigatran studies using capsules and
reconstitution solution. The increase in exposure is considered small enough
to consider the formulations interchangeable. Furthermore, trough levels were
similar for the 3 formulations. No conversion factor needs to be applied for
dosing purposes. Individuals with high peak or average exposure after intake
of dabigatran etexilate as hard capsule (R) did not show further exposure
increase with the other formulations.
Multiple 150 mg doses of dabigatran etexilate administrated as pellets on
food (T1), granules resolved in reconstitution solution (T2), or as hard
capsules (R) were safe and well tolerated by the healthy subjects.
Palatability and acceptability of dabigatran etexilate as pellets on food (T1)
appeared to be better on a 5 category scale than that of dabigatran etexilate as
granules resolved in reconstitution solution (T2), although the 95% CIs
showed overlap.
