Trial Outcomes & Findings for A Study to Test Whether BI 706321 Combined With Ustekinumab Helps People With Crohn's Disease (NCT NCT04978493)

NCT ID: NCT04978493

Last Updated: 2025-09-04

Results Overview

Absolute change from baseline in Simple Endoscopic Score for Crohn's disease (SES-CD) at Week 12 is reported. The SES-CD is a numerical grading system composed of 4 variables (presence of ulcers, ulcerated surface, affected surface, presence of narrowings) recorded sequentially in 5 segments: rectum, left colon, transverse colon, right colon, ileum. Each variable is assigned a value from 0 to 3, and the total score, ranging from 0 to 56, is obtained by adding each variable. Higher values indicate worse endoscopic inflammation. To achieve a score of 56, the maximum score for the "presence of narrowings" variable has to be be 2 (not 3) for the four segments leading up to the ileum. The analysis was a restricted maximum likelihood (REML) based analysis of covariance (ANCOVA). For the ANCOVA model, absolute change in SES-CD score was the dependent variable, treatment group and baseline corticosteroid use (yes/no) were fixed effects and baseline SES-CD score was a continuous covariate.

Participant Flow

This was a Phase IIa, randomised, double-blind, placebo-controlled evaluation of male and female patients with Crohn's Disease (CD), using BI 706321 therapy in combination with a backbone ustekinumab induction regimen.

Subjects were screened for eligibility prior to participation in the trial. Subjects attended a specialist site which ensured that they (the subjects) met all inclusion and no exclusion criteria. Subjects were not to be allocated to a treatment group if any entry criteria were violated. Subjects signed and dated an informed consent form according to local regulatory and legal requirements, and were informed that they were free to withdraw their consent at any time without penalty or prejudice.

BI 706321 and Ustekinumab
Participants with moderately to severely active Crohn's Disease (CD) administered one dose of 8 milligram (mg) BI 706321 as tablets orally once per day in the morning for 12 weeks in conjunction with standard induction dosing of ustekinumab, followed by ustekinumab maintenance dosing for an additional 36 weeks. A single intravenous infusion of 260 mg ustekinumab (body weight ≤55 kilogram \[kg\]), 390 mg ustekinumab (body weight 55-85 kg), or 520 mg ustekinumab (body weight \>85 kg) was administered on Day 0, followed by subcutaneous injection of 90 mg ustekinumab every 8 weeks.
Placebo and Ustekinumab
Participants with moderately to severely active CD administered one dose of placebo matching BI 706321 as tablets orally once per day in the morning for 12 weeks in conjunction with standard induction dosing of ustekinumab, followed by ustekinumab maintenance dosing for an additional 36 weeks.

PRIMARY outcome

Timeframe: Within 28 days before randomization (baseline) and 12 weeks after first drug administration.

Population: Full analysis set (FAS): all randomized patients who received at least 1 dose of trial medication and have analyzable post-baseline data (observed or imputed) in at least 1 efficacy/biological/histological parameter. If a subject discontinued after 6 weeks and had an assessment during the Week 8 visit window, the change in SES-CD score at Week 8 was carried forward to the Week 12 time point and used. If there was no post-baseline endoscopic assessment, baseline value was carried forward.

Participants with moderately to severely active Crohn's Disease (CD) administered one dose of 8 milligram (mg) BI 706321 as tablets orally once per day in the morning for 12 weeks in conjunction with standard induction dosing of ustekinumab, followed by ustekinumab maintenance dosing for an additional 36 weeks. A single intravenous infusion of 260 mg ustekinumab (body weight ≤55 kilogram \[kg\]), 390 mg ustekinumab (body weight 55-85 kg), or 520 mg ustekinumab (body weight \>85 kg) was administered on Day 0, followed by subcutaneous injection of 90 mg ustekinumab every 8 weeks.
Placebo and Ustekinumab
n=25 Participants
Participants with moderately to severely active CD administered one dose of placebo matching BI 706321 as tablets orally once per day in the morning for 12 weeks in conjunction with standard induction dosing of ustekinumab, followed by ustekinumab maintenance dosing for an additional 36 weeks. A single intravenous infusion of 260 mg ustekinumab (body weight ≤55 kilogram \[kg\]), 390 mg ustekinumab (body weight 55-85 kg), or 520 mg ustekinumab (body weight \>85 kg) was administered on Day 0, followed by subcutaneous injection of 90 mg ustekinumab every 8 weeks.
Percentage of Patients With Biological Remission, Defined as C-Reactive Protein (CRP) < 5 mg/L and Faecal Calprotectin (FCP) < 250 ug/g at Week 48
12.5 Percentage of patients
Interval 4.3 to 31.0
16.0 Percentage of patients
Interval 6.4 to 34.7

SECONDARY outcome

Timeframe: Data was collected for 7 days prior to 12 weeks after first drug administration.

Population: Full analysis set (FAS): all randomized patients who received at least 1 dose of trial medication and have analyzable post-baseline data (observed or imputed) in at least 1 efficacy/biological/histological parameter. If there were data at visits before and after one with a missing outcome, data was imputed as success only if both neighboring visits represented a success, independently of whether the before and after observations were selected for analysis based on the pre-defined time windows.

Percentage of patients with clinical remission at Week 12, defined as a Crohn's Disease Activity Index (CDAI) score of \<150 is reported. The CDAI is comprised of eight variables which are summed after adjustment with a weighting factor, and the total score ranges from 0 to approximately 600, with higher scores indicating more severe disease. For certain variables (daily number of liquid or very soft stools, daily abdominal pain, daily general well-being, fever over 37.8 Celsius, taking medication for diarrhea) the average over 7 days was taken. The method to provide confidence intervals for single proportions is based on the Wilson method.
