Masking description

Part 1a of this trial is a randomized, single-blind, and placebo-controlled. Part 1b of the trial is randomized, open-label, and with a two-way crossover design. Part 2 of the trial is single-blind, randomized, and placebo-controlled.

Intervention model description

This trial will be conducted in 2 parts: Part 1 (single doses) and Part 2 (multiple doses). Part 1 comprises of 2 subparts: Parts 1a and 1b. Part 1b starts only after the dose has been tested in part 1a and was safe and of acceptable tolerability. Part 2 of the study will only commence after the successful administration of the planned dose to the last subject in part 1a.

Inclusion criteria

1. Healthy male subjects according to the assessment of the investigator, as based on a complete medical history including a physical examination and clinical laboratory. 2. Age of 18 to 50 years (inclusive) 3. BMI of 18.5 to 29.9 kg/m² (inclusive), body weight above 60 kg (inclusive) 4. Signed and dated written informed consent in accordance with ICH-GCP and local legislation prior to admission to the trial.

Exclusion criteria

1. Any finding in the medical examination (including blood pressure (BP), pulse rate (PR) or electrocardiogram (ECG)) deviating from normal and assessed as clinically relevant by the investigator 2. Repeated measurement at screening 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 50 to 90 beats per minute (bpm) 3. Any laboratory value outside the (age-adapted) reference range that the investigator considers to be of clinical relevance, in particular, hepatic parameters (alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin), renal parameters (creatinine) exceeding the upper limit of normal (ULN) after repeated measurements or abnormal thyroid stimulating hormone (TSH) values outside of the normal range after repeated measurements. 4. Any evidence of a concomitant disease assessed as clinically relevant by the investigator Further
