A Study in Healthy People to Compare 3 Different Formulations of Apremilast Tablets Taken With or Without Food

The aim of this trial is to establish bioequivalence between EU-, US- and Japan-sourced Otezla® tablet formulations to assure comparability of results from Phase III trials of BI 730357 (new oral agent for treatment of psoriasis as well as other T helper 17 cells (Th17)-mediated diseases) regardless of whether only the EU-sourced Otezla® or EU and US-sourced Otezla®/Japan-sourced Otezla® have been used as an active comparator.


Eligibility Criteria:
Inclusion Criteria:

* Healthy male or female subjects according to the assessment of the investigator, as 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 of 18 to 55 years (inclusive)
* Body mass index (BMI) of 18.5 to 29.9 kg/m2 (inclusive)
* Signed and dated written informed consent prior to admission to the study, in accordance with Good Clinical Practice (GCP) and local legislation
* Male subjects, or female subjects who meet any of the following criteria for a highly effective contraception from at least 30 days before the first administration of trial medication until 30 days after trial completion:

  * Use of combined (estrogen and progestogen containing) hormonal contraception that prevents ovulation (oral, intravaginal or transdermal), plus condom
  * Use of progestogen-only hormonal contraception that inhibits ovulation (only injectables or implants), plus condom
  * Use of intrauterine device (IUD) or intrauterine hormone-releasing system (IUS)
  * A vasectomised sexual partner (vasectomy at least 1 year prior to enrolment)
  * Surgically sterilised (including hysterectomy or bilateral occlusion)
  * Postmenopausal, defined as no menses for 1 year without an alternative medical cause (in questionable cases a blood sample with levels of Follicle-stimulating hormone (FSH) above 40 U/L and estradiol below 30 ng/L is confirmatory)

Exclusion Criteria:

* Any finding in the medical examination (including BP, PR or ECG) deviating from normal and assessed as clinically relevant by the investigator
* Repeated 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
* Any laboratory value outside the reference range that the investigator considers to be of clinical relevance
* Any evidence of a concomitant disease assessed as clinically relevant by the investigator
* Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders
* Cholecystectomy or other surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy or simple hernia repair)
* 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 Further exclusion criteria apply.
