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   44339   clinical trials with a EudraCT protocol, of which   7369   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 ).

    General information about the trial
    Main objective of the trial
    The main objective of this study was to evaluate the clinical efficacy of D9421-C 9 mg once daily compared to Mesalazine 1 g three times a day to patients with mild to moderate active Crohn's disease affecting ileum, ileocecal region and/or ascending colon as defined by a score of 180-400 on the Crohn's Disease Activity Index (CDAI) by assessment of the remission after 8-week treatment defined by a CDAI score of ≤ 150.
    Protection of trial subjects
    If patients had any AE at the end of treatment, the AEs were followed by Investeigators until the investigators judged it was unnecessary to follow the AE.

    		 Proportion of patients with remission at Week 8
    End point description
    For the primary efficacy variable “Remission after 8 weeks of treatment”, Crohn’s Disease Activity Index CDAI scores was used to determine the patient’s response. Remission for this study is defined as a CDAI score of ≤150. A patient who drops out without any remission before week 8 was considered as a nonresponder (no remission) for this analysis. A patient who drops out before Week 8, but was in remission at the time of dropout, was considered in remission after dropout in this analysis.

    Notes
    [1] - A 2-sided 90% CI for the observed difference in the remission rates between the D9421-C 9mg group and the Mesalazine 3 g group was calculated using the Newcombe-Wilson score method without continuity correction. Noninferiority was concluded if the lower limit of the 90% CI was higher than –10% in FAS Population.

    Crohn’s Disease Activity Index (CDAI) score is calculated based on the data collected in the diary card. The patients is asked to fill the following items in the diary card (from the morning in preceding day to the morning in current day). (1) Number of liquid or very soft stools (2) Abdominal pain rating (none, mild, moderate, severe) (3) General well-being (generally well, slightly under par, poor, very poor, terrible) (4) Body temperature (if a patient feels fever) (5) Intake of loperamide or other opiates for diarrhoea. The data for the calculation of CDAI score in diary card is then transcribed by the investigator(s) into the eCRFs at each clinical visit. The higher total CDAI score indicates severe condition and total CDAI score 150 less or equal is evaluated as a remission.

    The Inflammatory Bowel Disease Questionnaire (IBDQ) is a standard measure of HRQL in Crohn's disease patients (Guyatt G et al 1989). The validated Japanese version of the IBDQ was used in this study (Hashimoto H et al 2003). The IBDQ contains 32 questions; each with seven possible answers ranging from 1 to 7, where 7 is the most favourable. Ten questions are related to bowel symptoms, five to systemic symptoms, twelve to emotional function, and five to social function. The corresponding answers will be added to form four subscores and a total score: bowel function score (10 – 70), systemic symptom score (5 – 35), emotional function score (12 – 84), social function score (5 – 35) and the total score (32 – 224), with higher scores indicating more favorable outcome.

The corresponding answers will be added to form four subscores and a total score: bowel function score (10 – 70), systemic symptom score (5 – 35), emotional function score (12 – 84), social function score (5 – 35) and the total score (32 – 224), with higher scores indicating more favorable outcome.

    		 Change in IBDQ scores from baseline to Week 10 - Social function
    End point description
    The Inflammatory Bowel Disease Questionnaire (IBDQ) is a standard measure of HRQL in Crohn's disease patients (Guyatt G et al 1989). The validated Japanese version of the IBDQ was used in this study (Hashimoto H et al 2003). The IBDQ contains 32 questions; each with seven possible answers ranging from 1 to 7, where 7 is the most favourable. Ten questions are related to bowel symptoms, five to systemic symptoms, twelve to emotional function, and five to social function. The corresponding answers will be added to form four subscores and a total score: bowel function score (10 – 70), systemic symptom score (5 – 35), emotional function score (12 – 84), social function score (5 – 35) and the total score (32 – 224), with higher scores indicating more favorable outcome.
