In plain English
What this trial is testing
This study is testing Tulisokibart (a drug) as a possible treatment. Condition(s) listed: Crohn Disease and Colitis, Ulcerative.
Some participants receive a placebo or sham for comparison.
It is blinded: participants and the study team do not know who receives what.
Phase 3 studies are large studies comparing a treatment with placebo or standard care. They are often the last step before a company asks regulators for approval.
Who can join
- Age range not stated in the record
- Any sex
Some of the main requirements, copied from the record:
- Has participated in a qualifying tulisokibart Phase 2 or Phase 3 parent study for CD or UC
- The investigator determines that the participant derives clinical benefit from continued study intervention based upon clinical evaluations performed during their parent study
- A participant assigned female sex at birth is not breastfeeding during the study intervention period and for at least 14 weeks after the last dose of study intervention
- A participant of childbearing potential (POCBP) is not pregnant and has a negative highly sensitive pregnancy test (urine or serum) as required by local regulations within 24 hours (for a urine test) or 72 hours (for a serum test) before…
- A POCBP uses an acceptable contraceptive method, or adheres to penile-vaginal intercourse abstinence as their preferred and usual lifestyle (abstinent on a long-term and persistent basis)
There are also 3 reasons someone might not be able to join (exclusion criteria). Only the trial team can confirm whether you qualify.

In the researchers’ words
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.
