About this study

Official title: An Open-label Phase 1 PET Imaging Trial to Investigate [89Zr]Zr-BI 764532 Biodistribution and Tumour Uptake in Patients With Small-cell Lung Carcinoma or Neuroendocrine Carcinoma

This study is open to adults with small cell lung cancer and other neuroendocrine cancers. The study is in people with advanced cancer for whom previous treatment was not successful or no standard treatment exists. The purpose of this study is to find out how a medicine called BI 764532 gets distributed in the body and in tumours.

Participants get BI 764532 when starting treatment. In the first weeks, doctors check how BI 764532 is taken up in tumours by means of an imaging method. If there is benefit for the participants and if they can tolerate it, the treatment is given up to the maximum duration of the study. During this time, participants visit the study site regularly. The total number of visits depends on how they respond to and tolerate the treatment. Doctors record any unwanted effects and regularly check the general health of the participants.

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 764532 and [89Zr]Zr-BI 764532 in people with Small Cell Lung Carcinoma (SCLC) and Neuroendocrine Neoplasms, run by Boehringer Ingelheim at 1 site in Netherlands.

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 10 inclusion and 15 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: looking for participants now, as of the sponsor's last update on 14 Oct 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 Netherlands. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Boehringer Ingelheim (1-800-243-0127, clintriage.rdg@boehringer-ingelheim.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean relative change from baseline of [89Zr]Zr-BI 764532 tumour-to-plasma ratios in all detectable lesions post BI 764532 doses (time frame: at baseline and up to 35 days). 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 14 Oct 2026.
