A Study of BI 3810944 in Patients With Advanced Cancer

May 12, 2026 updated by: Boehringer Ingelheim

A First-in-human, Phase I, Open-label, Non-randomized, Multicentre Dose Escalation and Expansion Trial of BI 3810944 in Patients With Solid Tumours and Melanoma

This study is open to adults with advanced cancer (solid tumours) for whom previous treatment was not successful, or no treatment exists. The study tests different doses of BI 3810944 to find out which doses they can tolerate. Another purpose is to identify the most suitable dose of BI 3810944 and to find out whether it helps people with advanced cancer. BI 3810944 may help fight cancer.

Participants get BI 3810944 usually once every 3 weeks. At treatment start, it is given once a week for a short time. Participants may continue to get BI 3810944 as long as they benefit from treatment but no longer than 2 years. During this time, they regularly visit the study site. The first study visits include overnight stays at the hospital. At the visits, study doctors check participants' health, take necessary laboratory tests, and note any unwanted effects.

The doctors also regularly check the size of the tumour with imaging methods.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

IPD Plan Description

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).
