Brief Summary
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) and TAK-279-UC-2001 (NCT06254950). 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 2 years (108 weeks). During the study, participants will visit their study clinic 11 times.

Outcome Measures
Primary Outcomes (4)
Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Adverse Events of Special Interest (AESIs)
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.
From start of study drug administration up to Week 112 (current study)
Number of Participants With Clinically Significant Changes in Vital Sign Values
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.
From start of study drug administration up to Week 112 (current study)
Number of Participants With Clinically Significant Changes in Clinical Laboratory Values
Laboratory parameters include hematology, clinical chemistry and urinalysis. Clinical significance of laboratory values will be determined at the investigator's discretion.
From start of study drug administration up to Week 112 (current study)
Number of Participants With Clinically Significant Changes in 12-lead Electrocardiogram (ECG) Values
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.
At Day 1 and Week 108 (current study)

Study Arms (2)
Crohn's Disease: Zasocitinib
EXPERIMENTALParticipants with Crohn's Disease (CD) who completed Week 52 of the parent study, TAK-279-CD-2001 (NCT06233461) will be enrolled in this open-label extension trial to receive Zasocitinib, orally, once daily for up to 108 weeks.
Ulcerative Colitis: Zasocitinib
EXPERIMENTALParticipants with Ulcerative Colitis (UC) who completed Week 52 of the parent study, TAK-279-UC-2001 (NCT06254950) will be enrolled in this open-label extension trial to receive Zasocitinib, orally, once daily for up to 108 weeks.
Interventions
Zasocitinib capsules.
Eligibility Criteria
You may qualify if:
- 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 phase 2 CD and UC trials 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 in PRO2 at parent trial Week 52, 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 parent trial Week 52, 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.
- Participants must meet the contraception recommendations.
You may not qualify if:
- 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.
- Participants taking oral corticosteroids for CD or UC during parent trial at or after Week 48.
