Study groups in NCT05833139
Study group	Role	What they receive
Zongertinib alone (R) / Zongertinib + itraconazole (T)	Experimental	Treatment Period 1: a single oral dose of 15 milligrams (mg) zongertinib, film-coated tablet, was administered once on Day 1 (Day 1, Period 1, Visit 2), as reference treatment R. Treatment Period 2: a single oral solution of 200 mg (10 mg/mL in a 20 milliliter (mL) solution) itraconazole was administered once daily over 14 days ([total: 14 doses], from Day -3 to Day 11, Period 2). On Day 1 (Day 1, Period 2, Visit 3), 4th day of itraconazole treatment, a single oral dose of 15 mg zongertinib was administered 1 hour (h) after itraconazole administration as test treatment T. The two administrations of zongertinib were separated by a washout interval of at least 14 days. Zongertinib and itraconazole were orally administered with 240 mL of water after an overnight fast of at least 10 h for zongertinib and 9 h for itraconazole.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Zongertinib and Itraconazole 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 8 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 22 Sep 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 22 Sep 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 Zongertinib in Plasma Over the Time Interval From 0 Extrapolated to Infinity (AUC0-∞) (time frame: Within 3 hours (h) prior to, and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24, 34, 47, 71, 119, 167 h for both periods, and additionally at 191, 215, 239, 263, and 287 h for period 2, after zongertinib 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 NCT05833139.

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 22 Sep 2025.
