Inclusion criteria
General criteria * Signed informed consent prior to any study-mandated procedure. * Healthy male subjects (both study parts) and female subjects of nonchildbearing potential (Part B) aged between 18 and 55 years (inclusive) at Screening. * Healthy on the basis of medical history, physical examination, cardiovascular assessments, and clinical laboratory tests. * Male subjects with a partner that might become pregnant must either be vasectomized or agree to practice adequate contraception from admission to the study site until 3 months after dosing, or the partner must consistently and correctly use (from Screening, during the entire study, and for at least 3 months after last study treatment intake) a highly effective method of contraception. Criteria for Part B only: • Women of non-childbearing potential must have a negative serum pregnancy test at Screening and a negative urine pregnancy test on Day-1.
Exclusion criteria
* Previous exposure to the study medication. * Any circumstances or conditions, which, in the opinion of the investigator, may affect full participation in the study or compliance with the protocol. * History or clinical evidence of any disease and/or existence of any surgical or medical condition, which, in the opinion of the investigator, are likely to interfere with the absorption, distribution, metabolism, or excretion of the study treatment. * Relevant bacterial, viral, fungal, or protozoal infection that manifested within the last 6 weeks prior to Screening and/or ongoing relevant bacterial, viral, fungal, or protozoal infection, as judged by the investigator, and/or evidence of immune dysfunction based on laboratory tests at Screening. * Any signs or symptoms of active, ongoing infection judged to be clinically relevant by the investigator (special attention should be given to clinical signs and symptoms consistent with COVID-19, e.g., fever, dry cough, dyspnea, sore throat, or fatigue).
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Safety profile including incidence of treatment-emergent adverse events. | Safety and tolerability assessments will be performed at predefined time points from Day 1 to Day 4 in Part A and Day 1 to Day 10 in Part B (total duration: max. 50 days). |
Secondary
| Measure | Time frame |
|---|---|
| Part A - Single ascending dose (SAD): Area under the plasma concentration-time curve (AUC) from zero to time t of the last measured concentration above the limit of quantification (AUC0-t). | Blood samples for the determination of the PK parameters will be collected at predefined time points from Day 1 to Day 4 (total duration: max. 4 days). |
| Part A - Single ascending dose (SAD): Area under the plasma concentration-time curve (AUC) from zero to infinity (AUC0-inf). | Blood samples for the determination of the PK parameters will be collected at predefined time points from Day 1 to Day 4 (total duration: max. 4 days). |
| Part A - Single ascending dose (SAD): Maximum plasma concentration (Cmax). | Blood samples for the determination of the PK parameters will be collected at predefined time points from Day 1 to Day 4 (total duration: max. 4 days). |
| Part A - Single ascending dose (SAD): Time to reach Cmax (tmax). | Blood samples for the determination of the PK parameters will be collected at predefined time points from Day 1 to Day 4 (total duration: max. 4 days). |
| Part A - Single ascending dose (SAD): Terminal half-life (t½). | Blood samples for the determination of the PK parameters will be collected at predefined time points from Day 1 to Day 4 (total duration: max. 4 days). |
| Part B - Multiple ascending dose (MAD): AUC during a dosing interval (AUCτ) following the first and the last dose. | Blood samples for the determination of the PK parameters will be collected at predefined time points from Day 1 to Day 10 (total duration: max. 10 days). |
| Part B - Multiple ascending dose (MAD): Cmax of the first and the last dosing interval. | Blood samples for the determination of the PK parameters will be collected at predefined time points from Day 1 to Day 10 (total duration: max. 10 days). |
| Part B - Multiple ascending dose (MAD): tmax of the first and the last dosing interval. | Blood samples for the determination of the PK parameters will be collected at predefined time points from Day 1 to Day 10 (total duration: max. 10 days). |
| Part B - Multiple ascending dose (MAD): t½ after last dose administration. | Blood samples for the determination of the PK parameters will be collected at predefined time points from Day 1 to Day 10 (total duration: max. 10 days). |
