About this study

Official title: A Phase 3 Extension Study to Evaluate the Long-term Safety and Efficacy of Tulisokibart in Participants With Crohn's Disease or Ulcerative Colitis

Researchers want to learn more about tulisokibart (also known as MK-7240) in an extension study. Tulisokibart is a medicine designed to treat active, moderate to severe Crohn's disease (CD) and ulcerative colitis (UC). An extension study is a type of study where people who received tulisokibart in certain other studies for CD or UC (called a parent study) may be able to join this study. The goals of this study are to learn about the safety of tulisokibart over time in people with CD or UC, and if people tolerate it.

Being tested
Tulisokibart, Placebo to tulisokibart
Medical subject headings
Crohn Disease, Colitis, Ulcerative

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TulisokibartDrug

    Also called MK-7240

    Humanized monoclonal antibody that binds human tumor necrosis factor-like cytokine 1A (TL1A), administered subcutaneously

  • Placebo to tulisokibartDrug

What is being measured

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

  1. Number of Participants Who Experience an Adverse Event (AE)

    An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who experience an AE will be reported.

    Measured: Up to approximately 378 weeks

  2. Number of Participants Who Discontinue Study Treatment Due to an AE

    An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who discontinue study treatment due to an AE will be reported.

    Measured: Up to approximately 364 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Tulisokibart in people with Crohn Disease and Colitis, Ulcerative, run by Merck Sharp & Dohme LLC at 37 sites in 7 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 3 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 3 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 37 sites in Poland, United States, France, Czechia, Hungary and 2 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 Toll Free Number (1-888-577-8839, Trialsites@msd.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants Who Experience an Adverse Event (AE) (time frame: Up to approximately 378 weeks). 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 NCT06651281.

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 3 Nov 2026.
