About this study

Official title: Phase IIa, Sequential Cohort, Open-label, Multi-center Clinical Trial to Evaluate the Efficacy, Safety, and Tolerability of Intravenous Induction and Subcutaneous Maintenance Treatment With BI 3032950 in Patients With Moderate to Severe Ulcerative Colitis

Adults between 18 and 80 years of age with ulcerative colitis can participate in this study. This is a study for people for whom previous treatment was not successful or who stopped previous treatment. The purpose of this study is to find out whether BI 3032950 helps people with ulcerative colitis.

This study has 2 parts. In Part A, participants get BI 3032950 as an infusion into a vein every 4 weeks. After 12 weeks, doctors check whether the signs and symptoms of ulcerative colitis have improved. Before the results of this assessment are available, participants move on to Part B and get BI 3032950 as an injection under the skin. Participants whose results show clinical response after 12 weeks can continue treatment with BI 3032950. They get BI 3032950 injections under the skin every 4 weeks for up to 2 years.

Participants visit their doctors every 4 weeks. During these visits, the doctors check the signs and symptoms of ulcerative colitis. This includes taking blood and stool samples. Doctors also do endoscopies. This is a procedure that uses a tube with a camera to look inside the body.

The doctors also regularly check participants' health and take note of any unwanted effects.

Being tested
BI 3032950 intravenous (Part A), BI 3032950 subcutaneous (Part B)

What is being measured

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

  1. Proportion of patients with clinical remission defined by the modified Mayo Score [mSC] with mSC of 0 to 2, including stool frequency subscore [SFS] of 0 or 1, rectal bleeding subscore [RBS] of 0, and centrally-read endoscopy subscore [ESS] of 0 or 1

    The modified Mayo score (mMS) consists of 3 components

    1. Stool frequency subscore (SFS)
    2. Rectal bleeding subscore (RBS)
    3. Endoscopy subscore (ESS) Each component is graded from 0 = none to 3 = severe. The overall range of the mMS is from 0 to 9 with a higher score indicating a worsening of the symptoms.

    Measured: Up to Week 12

Secondary outcomes (7)
  1. Endoscopic remission (defined as centrally-read ESS of 0)

    The endoscopy subscore (ESS) is graded from 0 = none to 3 = severe. The ESS is part of the modified Mayo score.

    Measured: Up to Week 12

  2. Clinical response (defined as a decrease from baseline in mMS ≥2 and at least a 30% reduction from baseline, and a decrease in RBS of ≥1 or an absolute RBS of 0 or 1)

    The modified Mayo score (mMS) consists of 3 components

    1. Stool frequency subscore (SFS)
    2. Rectal bleeding subscore (RBS)
    3. Endoscopy subscore (ESS) Each component is graded from 0 = none to 3 = severe. The overall range of the mMS is from 0 to 9 with a higher score indicating a worsening of the symptoms.

    Measured: Up to Week 12

  3. Endoscopic improvement (defined as centrally-read ESS of 0 or 1)

    The endoscopy subscore (ESS) is graded from 0 = none to 3 = severe. The ESS is part of the modified Mayo score.

    Measured: Up to Week 12

  4. Modified Mayo Score change from baseline

    The modified Mayo score (mMS) consists of 3 components

    1. Stool frequency subscore (SFS)
    2. Rectal bleeding subscore (RBS)
    3. Endoscopy subscore (ESS) Each component is graded from 0 = none to 3 = severe. The overall range of the mMS is from 0 to 9 with a higher score indicating a worsening of the symptoms.

    Measured: Up to Week 12

  5. Stool frequency subscore of 0 or 1

    The stool frequency (SFS) is graded from 0 = none to 3 = severe. The SFS is part of the modified Mayo score.

    Measured: Up to Week 12

  6. Rectal bleeding subscore of 0

    The rectal bleeding subscore (RBS) is graded from 0 = none to 3 = severe. The RBS is part of the modified Mayo score.

    Measured: Up to Week 12

  7. Occurrence of treatment-emergent adverse events (AEs)

    Measured: Up to Week 12 and up to Week 104

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing BI 3032950 intravenous (Part A) and BI 3032950 subcutaneous (Part B) in people with Ulcerative Colitis, run by Boehringer Ingelheim at 41 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 5 inclusion and 9 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 21 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 41 sites in Poland, United States, Serbia, Slovakia, Belgium 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. 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?

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?

Proportion of patients with clinical remission defined by the modified Mayo Score [mSC] with mSC of 0 to 2, including stool frequency subscore [SFS] of 0 or 1, rectal bleeding subscore [RBS] of 0, and centrally-read endoscopy subscore [ESS] of 0 or 1 (time frame: Up to Week 12). 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 21 Aug 2026.
