A Continuation Study of TAK-279 in Adults With Ulcerative Colitis (UC) and Crohn's Disease (CD)

Phase 2

Not yet recruiting

• Conditions: Crohn's Disease; Ulcerative Colitis
• Interventions: Drug: Zasocitinib

• Registration Number: NCT06764615
• Lead Sponsor: Takeda

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.

Arm && Interventions

Group	Intervention	Description
Crohn's Disease: Zasocitinib	Zasocitinib	Participants 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.

Primary Outcome Measures

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

Secondary Outcome Measures

Name	Time	Method
Percentage of CD Participants Achieving Clinical Remission Based on the Crohn's Disease Activity Index (CDAI)	Up to Week 108 (current study)	Clinical remission is defined as a CDAI score of less than (\<) 150 points.

The SES-CD score ranges from 0 to 56 which includes 4 endoscopic variables (intestinal surface affected by ulcers, intestinal surface affected by other inflammatory lesions, presence of ulcers, and presence of narrowing).
Percentage of CD Participants Achieving Endoscopic Remission Based on SES-CD	At Weeks 48 and 108 (current study)	Endoscopic remission is defined as SES-CD score \<4 or \<2 for ileal disease, no sub-score \>1. The SES-CD score ranges from 0 to 56 which includes 4 endoscopic variables (the intestinal surface affected by ulcers, the intestinal surface affected by other inflammatory lesions, the presence of ulcers, and the presence of narrowing).
Percentage of CD Participants With Clinical Remission in 2-item Patient-reported Outcome Measure (PRO2)	Up to Week 108 (current study)	Clinical remission based on PRO2 is defined as average daily liquid or very soft stool frequency (SF) score less than or equal to (\<=) 2.8 and not worse than parent study baseline and average daily abdominal pain (AP) score \<=1 and not worse than baseline.
Percentage of CD Participants With a Clinical Response in PRO2	Up to Week 108 (current study)	Clinical response based on PRO2 is defined as greater than or equal to (\>=) 30% decrease in average daily very soft or liquid stools and/ or \>=30% decrease in average AP from parent study baseline.

The responses to the 13 items on the FACIT-Fatigue questionnaire are each measured on a 5-point Likert scale, where 0=Not at all, 1=A little bit, 2=Somewhat, 3=Quite a bit and 4=Very much. The total score ranges from 0 to 52. High scores represent less fatigue.
Percentage of UC or CD Participants With Inflammatory Bowel Disease Questionnaire (IBDQ) Total Score >=170	Up to Week 108 (current study)	The IBDQ is a 32-item questionnaire that measures 4 dimensions: bowel systems (10 items), emotional function (12 items), systemic function (5 items), and social function (5 items).
