Study of ABBV-668 Oral Capsules to Assess Adverse Events and Change in Disease Activity in Adult Participants With Moderate to Severe Ulcerative Colitis

Phase 2
Completed
Conditions
Ulcerative Colitis
Interventions
Registration Number
NCT05570006
Lead Sponsor
AbbVie
Brief Summary

Ulcerative colitis (UC) is a type of inflammatory bowel disease that causes inflammation and bleeding from the lining of the rectum and colon (large intestine). This study will assess how safe and effective ABBV-668 is in treating adult participants with UC. Adverse events and change in disease activity will be assessed.

ABBV-668 is an investigational drug being developed for the treatment of moderate to severe UC. Approximately 40 adult participants diagnosed with UC will be enrolled in approximately 30 sites globally.

Participants will receive oral capsules of ABBV-668 twice daily for 52-weeks and will undergo a 30 day follow-up period.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Achieving Endoscopic ImprovementWeek 8

Endoscopic Improvement is defined as Mayo Endoscopic Subscore (ESS) of 0 or 1. The Endoscopic subscore is scored from 0 (Normal appearance mucosa) to 3 (severe disease, spontaneous bleeding, ulceration).

Number of Participants with Adverse Events (AEs)Up to approximately 56 weeks

An AE is defined as any untoward medical occurrence in a patient or clinical investigation in which a participant is administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants Achieving Clinical Response per Partial Adapted Mayo scoreWeek 8

Clinical response per Partial Adapted Mayo Score is defined as decrease from baseline ≥ 1 points and ≥ 30%, plus a decrease in RBS ≥ 1 or an absolute RBS ≤ 1. The Partial Adapted Mayo Score is a composite of the following subscores: Stool Frequency subscore and Rectal Bleeding subscore.

Percentage of Participants Achieving Endoscopic RemissionWeek 8

Endoscopic remission is defined as Mayo Endoscopic Subscore (ESS) = 0. The Endoscopic subscore is scored from 0 (Normal appearance mucosa) to 3 (severe disease, spontaneous bleeding, ulceration).

Percentage of Participants Achieving Clinical Remission per Adapted Mayo ScoreWeek 8

Clinical Remission per Adapted Mayo Score is defined as stool frequency subscore (SFS) ≤ 1, and not greater than baseline, rectal bleeding subscore (RBS) = 0, and endoscopic subscore (ESS) ≤ 1.The adapted Mayo Score is a composite of the following subscores: Stool Frequency subscore, Rectal Bleeding subscore and Endoscopy subscore.

Percentage of Participants Achieving Clinical Response per Adapted Mayo ScoreWeek 8

Clinical response per Adapted Mayo Score is defined as decrease from baseline ≥ 2 points and ≥ 30%, plus a decrease in RBS ≥ 1 or an absolute RBS ≤ 1. The adapted Mayo Score is a composite of the following subscores: Stool Frequency subscore, Rectal Bleeding subscore and Endoscopy subscore.
