About this study

Official title: A Phase II, Randomised, Double-blind, Parallel-group, 42-week Dose-finding Trial for BI 3034701 Administered Subcutaneously Compared to Placebo in Participants With Obesity or Overweight

This study is open to adults between 18 and 74 years of age and who have a body mass index (BMI) of 30 kg/m2 or more, or a BMI of 27 kg/m2 or more and at least 1 health problem related to their weight. People who have previously not managed to lose weight by changing their diet can participate. People with type 2 diabetes cannot take part in this study.

The purpose of this study is to find out whether a medicine called BI 3034701 helps people living with obesity or overweight to lose weight. This study has 7 groups of participants. Groups 1 to 6 get different doses of BI 3034701; Group 7 gets placebo. Placebo looks like BI 3034701 but does not contain any medicine. Every participant has more than an 80% chance of getting BI 3034701. Participants receive 2 injections of BI 3034701 or placebo under their skin for 42 weeks. In addition to the study medicine, all participants receive counselling to make changes to their diet and to exercise regularly.

Participants are in the study for about 10 months. During this time, they visit the study site 15 times. The study doctors regularly measure the participants' body weight and take necessary laboratory tests. Participants also answer questions about their well-being and note their food intake and physical activity in diaries. The results will be compared between groups of participants to see whether the treatment works. The study doctors also regularly check participants' health and take note of any unwanted effects.

  5. Absolute change from baseline at Week 42 in body weight [kg]

    Measured: Baseline and at Week 42.

  6. Absolute change from baseline at Week 42 in waist circumference [cm]

    Measured: Baseline and at Week 42.

  7. Absolute change from baseline at Week 42 in waist-to-height ratio (WHtR) [dimensionless ratio]

    Measured: Baseline and at Week 42.

  8. Absolute change from baseline at Week 42 in systolic blood pressure (SBP) [mmHg]

    Measured: Baseline and at Week 42.

Individual data sharing
Yes: 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 2 study testing BI 3034701 in people with Obesity and Overweight, run by Boehringer Ingelheim at 54 sites in 6 countries.

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 6 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: under way, not looking for participants, as of the sponsor's last update on 13 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 54 sites in United States, Canada, China, United Kingdom, Australia and 1 more country. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

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?

Percentage change in body weight from baseline at Week 42 [%] (time frame: Baseline and at Week 42.). 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 13 Oct 2026.
