A Study in Healthy Men to Test How BI 1839100 is Taken up and Handled by the Body

Phase 1

Suspended

• Conditions: Healthy
• Interventions: Drug: BI 1839100 (C-14) formulation 1; Drug: BI 1839100; Drug: BI 1839100 (C-14) formulation 2

• Registration Number: NCT06572111
• Lead Sponsor: Boehringer Ingelheim

Brief Summary

This trial is conducted in healthy male subjects to evaluate the drug BI 1839100. The trial has two main parts. Part A aims to understand how BI 1839100 is processed in the body after an oral dose. It measures the total recovery of the drug and its radioactive label in urine and feces. It also determines the concentrations in blood plasma and investigates the drug's metabolic pathways. Part B aims to compare the absolute bioavailability of BI 1839100 when administered orally and intravenously.

Exclusion Criteria

1. Any finding in the medical examination (including blood pressure (BP), pulse rate (PR), or ECG that deviates from normal and is assessed as clinically significant by the investigator
2. Repeated measurement of systolic BP outside the range of 90 to 140 mmHg, diastolic BP outside the range of 50 to 90 mmHg, or PR outside the range of 45 to 90 bpm (subjects with PR values between 45 and 50 bpm may only be enrolled in case they have normal thyroid function (thyroid-stimulating hormone (TSH) and free thyroxine (FT4) at baseline-screening, no clinical symptoms associated with the bradycardia and no apparent signs of other diseases causing bradycardia such as hypothyroidism or heart conduction abnormalities)
3. Any laboratory value outside the reference range that the investigator considers to be of clinical significance
4. Any evidence of a concomitant disease assessed as clinically significant by the investigator
5. Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders assessed as clinically significant by the investigator
6. Cholecystectomy or other surgery of the gastrointestinal tract that could interfere with the Pharmacokinetics (PKs) of the trial medication (except appendectomy or simple hernia repair)
7. Diseases of the central nervous system (including but not limited to any kind of seizures or stroke), and other relevant neurological or psychiatric disorders assessed as clinically relevant by the investigator
8. History of significant orthostatic hypotension, fainting spells, or blackouts Further exclusion criteria apply.
