Description

Inclusion Criteria:

  1. Healthy male or female subject 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
  2. Age of 18 to 50 years (inclusive)
  3. Body mass index (BMI) of 18.5 to 29.9 kg/m2 (inclusive)
  4. Signed and dated written informed consent in accordance with the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use-Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial Further inclusion criteria apply.

Exclusion Criteria:

  1. Any finding in the medical examination (including BP, PR or ECG) deviating from normal and assessed as clinically relevant by the investigator
  2. Repeated measurement of systolic blood pressure outside the range of 90 to 140 millimetre of mercury (mmHg), diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the range of 50 to 90 beats per minute (bpm) at screening
  3. Any laboratory value outside the reference range that the investigator considers to be of clinical relevance, in particular, hepatic parameters (alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin) or renal parameters (creatinine) exceeding the upper limit of normal (ULN) at screening
  4. Any evidence of a concomitant disease assessed as clinically relevant by the investigator Further exclusion criteria apply

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Test treatment (T), then reference treatment (R): T-R

Healthy subjects were administered one tablet of nerandomilast (Formulation C2) (Test treatment - T). After a washout period of at least 10 days, subjects were administered one tablet of nerandomilast (Formulation C1 - phase 3 formulation) (Reference treatment - R).

Both treatments were administered orally with approximately 240 milliliters (mL) of water after an overnight fast of at least 10 hours (h). After drug administration, subjects additionally fasted for 4 h.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Area Under the Concentration-time Curve of Nerandomilast in Plasma Over the Time Interval From 0 to the Last Quantifiable Data Point (AUC0-tz)
Time Frame: Within 3 h prior to drug administration, and 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.5, 3, 3.5, 4, 6, 8, 12, 24, 34, 48, 58, 72, 96, 120, 144 h after drug administration.

Area under the concentration-time curve of nerandomilast (R-BI 1015550) in plasma over the time interval from 0 to the last quantifiable data point (AUC0-tz) is reported.

Geometric least square mean (adjusted geometric mean) and adjusted geometric standard error were calculated using an analysis of variance (ANOVA) model on the logarithmic scale. PK endpoints were log-transformed (natural logarithm) prior to fitting the ANOVA model, which included effects accounting for the following sources of variation: "subjects within sequences" as random effect, "sequence", "period" and "treatment" as fixed effects. These quantities were then back-transformed to the original scale.

IPD Plan Description

Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).
