Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Non-interventional questionnaire on the long term outcomes of ulcerative colitis patients on ustekimumab therapy. Patients are not contacted. Instead questionnaires to be distributed to the clinical trials site to determine how many patients are on the compassionate access for ustekinumab and their clinical well being.
The questionnaire will be undertaken by a site trial coordinator from the clinical trials unit from the relevant institution (hospital). These will be taken either as face-to-face or telephone consultations at the election of the site trial coordinator. The interview itself is expected to take up to 20 minutes, and will be corroborated from the clinical notes. This will be at a single time-point, and the date of this interview will be collected to determine the follow up time since enrolment in the UNIFI trial (and thus the duration they have been receiving the medication, ustekinumab).
All information will be collected retrospectively, though some of the clinical information from hospital records will have been entered prospectively. The information collected will be: demographics, baseline clinical and endoscopic severity, clinical and endoscopic severity at the end of the induction and the maintenance study, clinical relapse data, biochemical (C-reactive protein and faecal calprotectin)/endoscopic severity (total and partial Mayo score) /radiologic (computerised tomography, magnetic resonance imaging, ultrasound) since enrollment in the UNIFI trial. Furthermore all possible adverse events will be reported via interview with the patient, but also with review of the clinical notes. The above information is necessary to determine: the types of patients described, the baseline severity and initial response to ustekinumab in the cohort, as well as the subsequent efficacy and adverse event rate in the cohort on this medication.
This will be assessed at time that the trial coordinators are able to contact the consented patient, between July to December 2022

Outcomes
Primary outcome [1] 328257 0
Cessation of ustekimumab determined by review of medical records and telephone survey or in person interview of participants
Timepoint [1] 328257 0
Between July to December 2022 (since these patients have enrolled many years ago in UNIFI), they will be interviewed opportunistically when the clinical trial coordinators at the relevant sites are able to arrange a convenient day/time. The interview date will be recorded to determine the time since UNIFI commencement and the dates they first received ustekinumab within the trial to determine the time since trial commencement.
Secondary outcome [1] 398263 0
Clinical relapse, and time to clinical disease relapse.
Clinical relapse is defined as a recurrence of colitis symptoms with commensurate biochemical, endoscopic, histological, and/or radiological evidence of disease activity that led to commencement or dose escalation of medical therapy. Such symptoms were persistent watery diarrhoea and/or abdominal pain and/or rectal bleeding. These symptoms were then confirmed by an objective measure of activity (faecal calprotectin greater than 250ug/g from baseline, endoscopic activity with Mayo score 1, radiographic evidence of colitis via CT, MRI or USS). The exclusion of infection was required for the definition of a disease relapse (via stool culture and clinical assessment.

Between July to December 2022 (since these patients have enrolled many years ago in UNIFI), they will be interviewed opportunistically when the clinical trial coordinators at the relevant sites are able to arrange a convenient day/time. The interview date will be recorded to determine the time since UNIFI commencement and the dates they first received ustekinumab within the trial to determine the time since trial commencement.
Secondary outcome [2] 398264 0
Adverse outcome related to ustekimumab therapy. Telephone or face-to-face survey of participants. Examples include: injection site reactions, allergy to medication, infections, malignancies, need for abdominal surgery including colectomy
Timepoint [2] 398264 0
Between July to December 2022 (since these patients have enrolled many years ago in UNIFI), they will be interviewed opportunistically when the clinical trial coordinators at the relevant sites are able to arrange a convenient day/time. The interview date will be recorded to determine the time since UNIFI commencement and the dates they first received ustekinumab within the trial to determine the time since trial commencement.
Secondary outcome [3] 398265 0
Dose intensification of ustekinumab or escalation of co-therapy (dose-intensification or addition) for disease control. Telephone or face-to-face survey of participants, data-linkage to medical records.

Statistical methods / analysis
Data will be expressed as percentages with numbers, and median or mean (depending on data distribution) with standard deviations and interquartile ranges. Chi-square test will be used to compare categorical outcome variables.
Comparisons of continuous outcome variables will be analysed using Students t test and Mann-Whitney U tests for parametric and non-parametric variables respectively. Kaplan-Meier analysis will be used to describe cessation of ustekimumab. Univariate analysis will be performed first to identify risk factors associated with cessation of ustekimumab using a proportional Cox model, with subsequent multivariate analysis using a stepwise progression. Statistical significance was taken as P<0.05.

This study is retrospective in nature and thus size and power calculations are not applicable

Summary
Brief summary
Observational multicentre cohort study on the long term outcomes of ulcerative colitis patients on ustekimumab therapy (post UNIFI study, NCT02407236), including time to flare, need for escalation and co-therapy for disease control. Time on treatment will be assessed from the first dose of ustekinumab, and 'survival' analysis performed with time on medication (with resutls censored at any loss to follow up. The primary outcome is proportion of patients who relapsed on ustekinumab, defined as a recurrence of flare/colitis symptoms with commensurate biochemical, endoscopic, histological, and/or radiological evidence of disease activity that led to commencement or dose escalation of medical therapy
