What is being measured

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

Area Under the Concentration-time Curve of Nerandomilast in Plasma Over the Time Interval From 0 to the Last Quantifiable Data Point (AUC0-tz)
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.
Measured: 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.
Maximum Measured Concentration of Nerandomilast in Plasma (Cmax)
Maximum measured concentration of nerandomilast (R-BI 1015550) in plasma (Cmax) 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.
Measured: 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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Nerandomilast 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 1 Dec 2025. 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. 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 1 Dec 2025). 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?

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.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06393127.

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 1 Dec 2025.
