What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Occurrence of Any Treatment-emergent Adverse Event (AE) Assessed as Drug-related by the Investigator

    The occurrence of any treatment-emergent adverse event (AE) assessed as drug-related by the investigator is reported.

    Measured: From timepoint of drug administration plus the residual effect period, up to 4 days (96 hours) after drug administration.

Secondary outcomes (3)
  1. AUC0-tz (Area Under the Concentration-time Curve of BI 3731579 in Plasma Over the Time Interval From 0 to the Last Quantifiable Data Point)

    AUC0-tz (area under the concentration-time curve of BI 3731579 in plasma over the time interval from 0 to the last quantifiable data point) is reported.

    Measured: Measured within 3 hours prior to drug administration and at 0.25 hours (hrs), 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 34, 48 and 72 hrs after drug intake.

  2. AUC0-∞ (Area Under the Concentration-time Curve of BI 3731579 in Plasma Over the Time Interval From 0 Extrapolated to Infinity)

    AUC0-∞ (area under the concentration-time curve of BI 3731579 in plasma over the time interval from 0 extrapolated to infinity) is reported.

    Measured: Measured within 3 hours prior to drug administration and at 0.25 hours (hrs), 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 34, 48 and 72 hrs after drug intake.

  3. Cmax (Maximum Measured Concentration of BI 3731579 in Plasma)

    Cmax (maximum measured concentration of BI 3731579 in plasma) is reported.

    Measured: Measured within 3 hours prior to drug administration and at 0.25 hours (hrs), 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 34, 48 and 72 hrs after drug intake.

Individual data sharing
No: 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).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BI 3731579 in people with Healthy, run by Boehringer Ingelheim at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Aug 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Occurrence of Any Treatment-emergent Adverse Event (AE) Assessed as Drug-related by the Investigator (time frame: From timepoint of drug administration plus the residual effect period, up to 4 days (96 hours) after drug administration.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Aug 2026.
