Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • 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.

    Up to approximately 378 weeks

  • 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.

    Up to approximately 364 weeks

Secondary Outcomes (4)

  • Percentage of Participants with Crohn's Disease Achieving Clinical Remission per Crohn's Disease Activity Index (CDAI) Score

    Week 364

  • Percentage of Participants with Crohn's Disease Achieving Clinical Remission per Stool Frequency and Abdominal Pain Score

    Week 364

  • Percentage of Participants with Crohn's Disease With Endoscopic Remission Per Simplified Endoscopic Score for Crohn's Disease (SES-CD)

    Week 364

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • 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 the first dose of study intervention
  • 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)

You may not qualify if:

  • Has prematurely discontinued study intervention in their parent study
  • Has received any protocol-specified prohibited medications during their parent study
  • Has known allergies, hypersensitivity, or intolerance to tulisokibart or its excipients

Masking Details
Participants in "Group 1: Low Dose Unblinded" and "Group 2: High Dose Unblinded" received open-label treatment on their parent studies, and will remain unblinded on this extension study. Participants in "Group 3: High Dose Blinded" and "Group 4: Low Dose Blinded" were all blinded on their parent studies, and will remain blinded on this extension study until after regulatory approval or market authorization in the United States or European Medicines Agency, per sponsor discretion.
