A Study of JNJ-78934804 in Participants With Moderately to Severely Active Ulcerative Colitis (DUET ENCORE-UC)

4. juni 2026 opdateret af: Janssen Research & Development, LLC

A Phase 3 Randomized, Double-blind, and Active Controlled, Multi-center Study to Evaluate the Efficacy and Safety of JNJ-78934804 in Participants With Moderately to Severely Active Ulcerative Colitis

The purpose of this study is to assess how well JNJ-78934804 works (efficacy) and how safe it is (safety) as compared to guselkumab at Week 48 in participants with moderately to severely active ulcerative colitis (UC, a chronic disease of the large intestine in which the lining of the colon becomes inflamed and develops ulcers).

Tidsramme
Percentage of Participants in Clinical Remission at Week 48
Tidsramme: At Week 48
Clinical remission is defined as an stool frequency (SF) subscore of 0 or 1, rectal bleeding (RB) subscore of 0, and an endoscopy subscore of 0 or 1.
At Week 48

Foranstaltningsbeskrivelse
Tidsramme
Percentage of Participants with Endoscopic Improvement at Week 48
Tidsramme: At Week 48
Endoscopic improvement is defined as an endoscopy subscore of 0 or 1.
At Week 48
Percentage of Participants with Corticosteroid-free (90 day) Clinical Remission at Week 48
Tidsramme: At Week 48
Corticosteroid-free (90 day) clinical remission is defined as clinical remission at the visit and not receiving corticosteroids for 90 days prior to the visit.
At Week 48
Percentage of Participants Achieving a Combination of Histologic Remission and Endoscopic Improvement at Week 48
Tidsramme: At Week 48
Endoscopic improvement is defined as an endoscopy subscore of 0 or 1. Histologic remission is defined as an absence of neutrophils from the mucosa (both lamina propria and epithelium), no crypt destruction, and no erosions, ulcerations or granulation tissue according to the Geboes grading system.
At Week 48
Percentage of Participants with Fatigue Response (PROMIS Fatigue Short Form 7a) at Week 48
Tidsramme: At Week 48
Fatigue response is defined as a greater than or equal to (>=) 7- point reduction in the patient-reported outcomes measurement information system (PROMIS) fatigue short form 7a total score from baseline. The PROMIS fatigue SF-7a contains 7 items evaluating fatigue-related symptoms (that is, tiredness, exhaustion, mental tiredness, and lack of energy) and associated impacts on daily activities (that is, activity limitations related to work, self-care, and exercise).
At Week 48
Percentage of Participants with Sustained Mayo SF Less Than or Equal to (<=) 1 and RB=0
Tidsramme: At Weeks 12, 24, and 48
Percentage of participants with a SF subscore of 0 or 1 and RB subscore of 0 at three assessment time points of Week 12, Week 24, and Week 48 will be reported.
At Weeks 12, 24, and 48
Percentage of Participants in Abdominal Pain Remission at Week 48
Tidsramme: At Week 48
Percentage of participants in abdominal pain remission at week 48 will be reported.
At Week 48
Percentage of Participants with Inflammatory Bowel Disease Questionnaire (IBDQ) Response at Week 48
Tidsramme: At Week 48
IBDQ response is defined as improvement from baseline in the total IBDQ score of >= 16 points. The IBDQ is a 32-item, self-reported questionnaire for participants with IBD that will be used to evaluate the disease-specific health-related quality of life (HRQoL) across 4 dimensional scores: bowel symptoms (loose stools, abdominal pain), systemic functions (fatigue, altered sleep pattern), social function (work attendance, need to cancel social events), and emotional function (anger, depression, irritability).
At Week 48
Percentage of Participants with PROMIS-29 Mental Component Summary (MCS) Response at Week 48
Tidsramme: At Week 48
PROMIS 29 MCS response is defined as a >= 7-point improvement from baseline in PROMIS 29 MCS response at Week 48. The PROMIS-29 is a collection of short forms containing 4 items for each of 7 domains (depression, anxiety, physical function, pain interference, fatigue, sleep disturbance, and ability to participate in social roles and activities). The PROMIS-29 MCS will be assessed, which is primarily informed by domains of emotional distress (depression/anxiety) and fatigue as well as sleep disturbance where higher MCS scores reflect better mental health.
At Week 48
Percentage of Participants in Clinical Remission at Week 12
Tidsramme: At Week 12
Clinical remission is defined as an SF subscore of 0 or 1, RB subscore of 0, and an endoscopy subscore of 0 or 1.

At Week 2
Percentage of Participants with Adverse Events (AE) and Serious AEs (SAEs)
Tidsramme: Up to approximately 3 years
An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the intervention. An SAE is any untoward medical occurrence that at any dose: results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/ incapacity, is a congenital anomaly/birth defect, is a suspected transmission of any infectious agent via a medicinal product, and is medically important.
