Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43865   clinical trials with a EudraCT protocol, of which   7286   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

    Recruitment
    Recruitment details
    		 The study included a Screening Period of up to 5 weeks, Part 1, and Part 2. Part 1 was a randomized, double-blind, placebo-controlled 8-week induction period. Part 2 was an open-label, 8 week extended treatment period for clinical non-responders from Part 1. A total of 522 subjects were randomized at 204 sites in 41 countries.

    Pre-assignment
    Screening details
    		 Participants were randomized in a 2:1 ratio to upadacitinib or placebo. Randomization was stratified by bio-IR status, corticosteroid use, and Adapted Mayo score at Baseline. Within bio-IR, randomization was further stratified by number of prior biologic treatments. Within non-bio-IR, randomization was further stratified by previous biologic use.

    Adapted Mayo Score
    The Adapted Mayo Score is a composite score of UC disease activity based on the following 3 subscores: 1) Stool frequency subscore (SFS), scored from 0 (normal number of stools) to 3 (5 or more stools more than normal). 2) Rectal bleeding subscore (RBS), scored from 0 (no blood seen) to 3 (blood alone passed). 3) Endoscopic subscore, scored from 0 (normal or inactive disease) to 3 (severe disease, spontaneous bleeding, ulceration). The overall Adapted Mayo Score ranges from 0 to 9 where higher scores represent more severe disease.

    End point description
    The Adapted Mayo Score is a composite score of UC disease activity based on the following 3 subscores: 1) Stool frequency subscore (SFS), scored from 0 (normal number of stools) to 3 (5 or more stools more than normal). 2) Rectal bleeding subscore (RBS), scored from 0 (no blood seen) to 3 (blood alone passed). 3) Endoscopic subscore, scored from 0 (normal or inactive disease) to 3 (severe disease, spontaneous bleeding, ulceration). The overall Adapted Mayo score ranges from 0 to 9 where higher scores represent more severe disease. Clinical Remission is defined as an Adapted Mayo score ≤ 2, with SFS ≤ 1 and not higher than Baseline, RBS of 0, and endoscopic subscore ≤ 1. The Part 1 intent-to-treat population (ITT1) includes randomized subjects who received at least 1 dose of study drug in Part 1. The ITT1 population excludes 6 subjects from 1 site with non-compliance. Non-responder imputation incorporating multiple imputation to handle missing data due to COVID-19 was used.

    		 Percentage of Participants Achieving Clinical Response per Adapted Mayo Score at Week 8
    End point description
    The Adapted Mayo Score is a composite score of UC disease activity based on the following 3 subscores: 1) Stool frequency subscore (SFS), scored from 0 (normal number of stools) to 3 (5 or more stools more than normal). 2) Rectal bleeding subscore (RBS), scored from 0 (no blood seen) to 3 (blood alone passed). 3) Endoscopic subscore, scored from 0 (normal or inactive disease) to 3 (severe disease with spontaneous bleeding, ulceration). The overall Adapted Mayo score ranges from 0 to 9 with higher scores representing more severe disease. Clinical response per the Adapted Mayo Score is defined as a decrease in Adapted Mayo score ≥ 2 points and ≥ 30% from Baseline, plus a decrease in RBS ≥ 1 or an absolute RBS ≤ 1. The analysis was conducted in the ITT1 population; non-responder imputation incorporating multiple imputation to handle missing data due to COVID-19 was used.

    The Inflammatory Bowel Disease Questionnaire (IBDQ) is used to assess health-related quality of life (HRQoL) in patients with ulcerative colitis. It consists of 32 questions evaluating bowel and systemic symptoms, as well as emotional and social functions. Each question is answered on a scale from 1 (worst) to 7 (best). The total score ranges from 32 to 224 with higher scores indicating better health-related quality of life. A positive change from Baseline indicates improvement. The analysis was conducted in the ITT1 population with available data; a mixed effect model repeat measurement (MMRM) analysis with data from observed cases up to Week 8 was used except for measurements at or after the occurrence of UC-related corticosteroids intercurrent event were excluded.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    12 Sep 2018
    Global amendment 1: ● Clarified the study objective to outline both the primary and secondary endpoints. ● Enhanced various sections of the protocol to clarify expectations and create better understanding of the content. ● Enhanced the description of the DMC review, the contacts list and signatories were updated to reflect changes in study team administration.
    24 Apr 2019
    Global amendment 2: ● Updating the study objective to include the secondary objectives. ● Updating the benefit risk language, modifying exclusion criterion #14 to allow for undetectable biologic levels to be measured via a commercially available assay as an alternative to the washout period, based on regulatory feedback. ● Adding the country-specific requirements in the inclusion/exclusion criteria (included 16 and 17-year-old subjects, where locally permitted). ● Adding, amending, and clarifying the study procedures. ● Adding justification for the use of placebo and further elaborating on the details of the DMC.
    29 Apr 2020
    Global amendment 3: ● Updated wording about re-testing of exclusionary laboratory values during the screening period. ● Clarified intervals for testing biologic drug levels. ● Updated the criteria of clinical response for entering extended treatment period for subjects with missing Week 8 endoscopy when endoscopies cannot be performed due to the COVID-19 pandemic. ● Moved non-ranked secondary efficacy variables to additional efficacy variables. ● Added criteria for failure of ustekinumab treatment, added wording to define borderline serum pregnancy test results, clarified that live vaccines should not be administered for at least 30 days prior to or after study drug administration. ● Excluded subjects with a history of gastrointestinal perforation (perforation due to mechanical injury should not exclude a subject from participation). ● Prohibited cytapheresis treatment for 60 days prior to screening. ● Excluded subjects with prior history of thrombotic events including deep vein thrombosis and pulmonary embolism or known inherited conditions that predispose to hypercoagulability. ● Added wording about gastric banding/segmentation to make clear that it is not an exclusion. ● Added wording to the washout requirements for all biologic therapies. ● Removed wording about women classified as non-childbearing potential. ● Updated ECG review requirements. ● Updated the type of QuantiFERON TB test used. ● Updated toxicity management for aspartate aminotransferase (AST) and alanine aminotransferase (ALT), thrombosis events, and herpes zoster
    31 Jul 2020
    Global amendment 4: Updated information on the re-evaluation of the benefit and risk to subjects participating in the study, updated wording to allow for changes in visits and procedures affected by the COVID-19 pandemic and associated changes in global/local regulations.
