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   44338   clinical trials with a EudraCT protocol, of which   7368   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Clinical remission at week 12 is defined as achieving a modified Mayo score (MMS) subscore for rectal bleeding=0,stool frequency=0 or 1 with ≥ 1 point decrease from baseline,and endoscopy=0 or 1 (excluding friability),excluding consideration of Physician's Global Assessment (PGA).Stool frequency subscore,based on the participants (pts) diary and scored from 0 (normal number of stools) to 3 (5 or more stools than normal);Rectal bleeding subscore,based on the pts diary and scored from 0 (no blood seen) to 3 (blood alone passed);Endoscopy subscore,based on colonoscopy or sigmoidoscopy and scored from 0 (normal or inactive disease) to 3 (severe disease,spontaneous bleeding, ulceration).The confidence interval (CI) of 99.875% was chosen to match the significance level. Analysis population description (APD): Modified Intention-to-treat population (mITT): All randomized pts who received at least one dose of study drug and who had MMS measured correctly at baseline.

    Symptomatic response at week 12 is defined as ≥30% decrease from baseline in the sum of stool frequency and rectal bleeding subscores. Stool frequency subscore, based on the participant's diary and scored from 0 (normal number of stools) to 3 (5 or more stools than normal). Rectal bleeding subscore, based on the participant's diary and scored from 0 (no blood seen) to 3 (blood alone passed). The sum of stool frequency and rectal bleeding subscores ranges from 0 to 6. APD:mITT: All randomized pts who received at least one dose of study drug and who had MMS measured correctly at baseline.

    		 Change from Baseline to Week 12 in Bowel Urgency Based on the Urgency Numeric Rating Scale (NRS)
    End point description
    The Urgency NRS is a single participant reported item that measures the severity for the urgency (sudden or immediate need) to have a bowel movement in the past 24 hours using an 11-point NRS ranging from 0 (no urgency) to 10 (worst possible urgency).Higher scores indicate more severe urgency. Least square (LS) Mean was calculated using mixed model repeated measures (MMRM) model for post-baseline measures: The MMRM model includes: treatment, baseline value, visit, interaction of baseline value-by-visit, interaction of treatment-by-visit, prior biologic or tofacitinib failure (yes/no), baseline corticosteroid use (yes/no), baseline disease activity (MMS: [4-6] or [7-9]), and region (North America/Europe/Other). APD:mITT: All randomized pts who received at least one dose of study drug and had a baseline and at least one post-baseline urgency NRS measurement.

    		 Change from Baseline to Week 12 in Health Related Quality of Life: Inflammatory Bowel Disease Questionnaire (IBDQ) Total Score
    End point description
    The IBDQ is a 32-item participant-completed questionnaire that measures 4 aspects of subjects' lives: symptoms directly related to the primary bowel disturbance, systemic symptoms, emotional function, and social function (Guyatt et al. 1989). Responses are graded on a 7-point. Likert scale in which 7 denotes "not a problem at all" and 1 denotes "a very severe problem." Scores range from 32 to 224; a higher score indicates a better quality of life. Least square (LS) Mean was calculated using analysis of covariance (ANCOVA) model for post-baseline measures: The ANCOVA model includes: treatment, baseline value, prior biologic or tofacitinib failure (yes/no), baseline corticosteroid use (yes/no), baseline disease activity (MMS: [4-6] or [7-9]), and region (North America/Europe/Other). APD: mITT: All randomized pts who received at least one dose of study drug and had a baseline and at least one post-baseline IBDQ measurement.

    Lilly made the decision to temporarily pause new participant accrual to LUCENT-1 (all countries with the exception of Japan, S.Korea, Taiwan, China). The interactive web-response system (IWRS) was closed to enter new participants at end of day (8 pm United States Pacific Daylight Time) on 25-March-2020. Enrolled participants could continue in the study provided the investigator affirmed that this was safe and in their best interest and in accordance with any local regulations and health advisories pertaining to the containment of the virus. The interruption was lifted May 7, 2020.
