A Continuation Study of TAK-279 in Adults With Ulcerative Colitis (UC) and Crohn's Disease (CD)
What this study is about
Crohn's Disease and Ulcerative Colitis are two types of inflammatory bowel disease (IBD), which is a serious, long-term condition in the gut (intestine) that can cause pain and swelling (inflammation) in the bowel. TAK-279 is a medicine which helps to block inflammation.
View original scientific description
Crohn's Disease and Ulcerative Colitis are two types of inflammatory bowel disease (IBD), which is a serious, long-term condition in the gut (intestine) that can cause pain and swelling (inflammation) in the bowel. TAK-279 is a medicine which helps to block inflammation. This study is an extension of the parent studies, TAK-279-CD-2001 (NCT06233461), TAK-279-UC-2001 (NCT06254950) and TAK-279-CD-2003 (NCT07403968). This means that participants who responded to treatment with TAK-279 in either of the parent studies may be able to continue to benefit from the treatment in this study. The main aim of this study is to find out how safe TAK-279 is for long term use and to check if it reduces bowel inflammation and symptoms when used for a longer period of time in adults with moderately to severely active UC or CD. The participants will be treated with TAK-279 for up to 3 years (156 weeks). During the study, participants will visit their study clinic around 15 times.

Primary outcome measures
All Cohorts: Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Adverse Events of Special Interest (AESIs)
Time frame: From start of study drug administration up to Week 160 (current study)
TEAE is defined as any event emerging or manifesting at or after the initiation of treatment with a study intervention or medicinal product or any existing event that worsens in either intensity or frequency following exposure to the study intervention or medicinal product. An AESI is an adverse event of scientific and medical concern specific to the compound or program, for which ongoing monitoring and rapid communication by the investigator may be appropriate.
All Cohorts: Number of Participants With Clinically Significant Changes in Vital Sign Values
Time frame: From start of study drug administration up to Week 160 (current study)
Vital sign values include body temperature, respiratory rate, sitting blood pressure (systolic and diastolic, resting more than 5 minutes), pulse (beats per minute). Clinical significance of vital signs will be determined at the investigator's discretion.
All Cohorts: Number of Participants With Clinically Significant Changes in Clinical Laboratory Values
Time frame: From start of study drug administration up to Week 160 (current study)
Laboratory parameters include hematology, clinical chemistry and urinalysis. Clinical significance of laboratory values will be determined at the investigator's discretion.
Cohorts 1 and 2: Number of Participants With Clinically Significant Changes in 12-lead Electrocardiogram (ECG) Values
Time frame: At Day 1 and Week 156 (current study)
ECGs will be performed with the participant in the supine or semi-supine position and after resting comfortably for at least 5 minutes. Clinical significance of 12-lead ECG values will be determined at the investigator's discretion.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- The participant is willing and able to understand and fully comply with trial procedures and requirements (including digital tools and applications), in the opinion of the investigator. The participant has provided informed consent (that is, in writing, documented via a signed and dated informed consent form \[ICF\]) and any required privacy authorization prior to the initiation of any trial procedures.
- Completion of Week 52 in the parent trials (phase 2b CD and phase 2 UC) with valid electronic (e) Diary data for Week 52 (TAK-279-CD-2001 and TAK-279-UC-2001).
- Clinical or symptomatic responder at parent trial Week 52 as defined below:
- TAK-279-CD-2001: Clinical response at Week 52 of the parent trial based on PRO2, assessed as \>=30% decrease in average daily very soft or liquid stools and/ or \>=30% decrease in average AP from parent trial baseline.
- TAK-279-UC-2001: Symptomatic response at Week 52 of the parent trial, assessed as a reduction in partial modified Mayo score (pmMS) of \>=1 points and \>=30% from parent trial baseline; and a decrease from parent trial baseline in the rectal bleeding sub-score of \>=1 point or an absolute rectal bleeding sub-score of \<=1 point.
- TAK-279-CD-2003: Endoscopic response at Week 12 of the parent trial, assessed as a participant achieving decrease in SES-CD \>50% from baseline (or for participants with isolated ileal disease, SES-CD \<=4 or at least a 2-point reduction from baseline). Other General Inclusion Criteria:
- Participants must meet the contraception recommendations.
Exclusion criteria
- Participant considered by the investigator to be unsuitable for the OLE trial due to their trial compliance and medication adherence concerns.
- Participants with malignancy or dysplasia per endoscopy any time during the parent trial or at the beginning of the OLE. Exclusion Criteria related to Laboratory Investigations:
- Participants meeting the exclusion criteria related to laboratory investigations as defined in the protocol. Exclusion criteria related to other prohibited concomitant medication for TAK-279-CD-2001 and TAK-279-UC-2001 Cohorts:
- Participants taking oral corticosteroids for CD or UC during parent trial at or after Week 48.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
