Bioequivalence of Tablet Formulation of Dabigatran Etexilate Compared to Commercial Capsule Formulation Following Oral Administration in Healthy Male Subjects

The primary objective of this trial is to establish the bioequivalence of tablet formulation of dabigatran etexilate compared to commercial capsule formulation following oral administration under fasted condition.

The secondary objective is the evaluation and comparison of several pharmacokinetic parameters between the treatments.


Eligibility Criteria:
Inclusion Criteria:

Subjects will only be included into the trial, if they meet the following criteria:

* Healthy male subjects according to the investigator's assessment, based on a complete medical history including a physical examination, vital signs (blood pressure (BP), pulse rate (PR)), 12-lead electrocardiogram (ECG), and clinical laboratory tests
* Age ≥20 and ≤40 years old at informed consent
* BMI ≥18 and ≤25 kg/m2 at screening
* Signed and dated written informed consent prior to admission to the trial in accordance with Good Clinical Practice (GCP) and local legislation

Exclusion Criteria:

Subjects will not be allowed to participate if any of the following general criteria apply:

* Any finding in the medical examination (including blood pressure (BP), pulse rate (PR)or electrocardiogram (ECG)) is deviating from normal and judged as clinically relevant by the investigator
* Measurement of systolic blood pressure outside the range of 90 to 140 mmHg, diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the range of 45 to 90 bpm at screening. Based on the clinical judge by the investigator, repeated measurements are allowed.
* Any laboratory value outside the reference range before randomisation that the investigator considers to be of clinical relevance
* Any evidence of a concomitant disease considered as clinically relevant by the investigator
* Any relevant bleeding history considered by the investigator
* Any history or evidence of blood dyscrasia, haemorrhagic diathesis, severe thrombocytopenia, cerebrovascular haemorrhage, bleeding tendencies associated with active ulceration or overt bleeding of gastrointestinal, respiratory or genitourinary tract or any disease or condition with haemorrhagic tendencies
* Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders
* Cholecystectomy and/or surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy and simple hernia repair)
* Planned surgeries within four weeks following the end-of trial examination
* Diseases of the central nervous system (including but not limited to any kind of seizures or stroke), and other relevant neurological or psychiatric disorders
* History of relevant orthostatic hypotension, fainting spells, or blackouts
* Chronic or relevant acute infections
* History of relevant allergy or hypersensitivity (including allergy to the trial medication or its excipients)
* Use of drugs within 30 days prior to administration of trial medication if that might reasonably influence the results of the trial (incl.Qc/QTc interval prolongation)
* Participation in another trial where an investigational drug has been administered within 60 days prior to planned administration of trial medication, or current participation in another trial involving administration of investigational drug
* Smoker (more than 10 cigarettes or 3 cigars or 3 pipes per day)
* Inability to refrain from smoking in-house confinement at the trial site
* Alcohol abuse (consumption of more than 30 g per day: e.g., 750 mL of beer, 1.5 gous \[equivalent to 270 mL\] of Sake)
* Drug abuse or positive drug screening
* Blood donation of more than 100 mL within 30 days prior to administration of trial medication or intended donation during the trial
* Intention to perform excessive physical activities within one week prior to administration of trial medication or during the trial
* Inability to comply with dietary regimen of trial site
* Subject is assessed as unsuitable for inclusion by the investigator, for instance, because considered not able to understand and comply with trial requirements, or has a condition that would not allow safe participation in the trial
