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   44334   clinical trials with a EudraCT protocol, of which   7366   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 ).

    TIS scores ranged from 0–100 with higher scores indicating a greater improvement. Scores were determined by summing scores in each of the 6 CSMs of the IMAC (physician, patient, extra-muscular global activity, muscle strength, HAQ, and muscle enzyme levels). Clinically meaningful thresholds for improvement were defined as ≥ 20 point improvement response on IMACS-TIS (TIS20; mild), ≥ 40 point improvement response on IMACS TIS (TIS40; moderate) and ≥ 60 point improvement response on IMACS-TIS (TIS60; severe). Scores were based on the improvement and relative weight of each CSM. Data are presented for TIS (least squares mean) at Week 26.

    The CDASI is an instrument that separately measures activity and damage in the skin of dermatomyositis (DM) participants. It is a 1-page instrument that contains 3 activity measures (erythema, scale, and erosion/ulceration) and 2 damage measures (poikiloderma and calcinosis). CDASI score is calculated by rating the severity of skin disease in 15 anatomical locations on the body based on activity and damage components. CDASI was completed by the Clinician/Clinician-Investigator. Total CDASI scores ranged from 0-100, higher scores =greater disease severity. Change from baseline in CDASI Total Activity Score at Week 26 was analyzed using a mixed model repeated measures (MMRM). The MMRM model included the observed Total Activity Score values at post baseline visits (Week 26) as the dependent variable.

CDASI score is calculated by rating the severity of skin disease in 15 anatomical locations on the body based on the activity and damage components. CDASI was completed by the Clinician or Clinician-Investigator while examining the participant. Total CDASI scores ranged from 0-100, with higher scores indicating a greater disease severity. Data are presented for the number of participants with a CDASI response. Response was defined as a >=7 point improvement in participants who did not have an intercurrent event at or prior to the relevant timepoint. Randomized Set, which included all randomized participants grouped by randomized treatment group.

    		 Change from Baseline In IMACS CSMs: Health Assessment Questionnaire (HAQ) at Week 26
    End point description
    The HAQ is a brief self-report questionnaire that assesses physical function pertaining to activities of daily living in a variety of domains. The HAQ includes 20 questions relating to 8 domains of function: dressing and grooming, arising, eating, walking, hygiene, reach, grip and usual activities. For each of the categories, participants reported the amount of difficulty they had in performing 2 or 3 specific subcategory items. The standard disability score is calculated from the 8 categories by dividing the sum of the individual categories by the number of categories answered, yielding a score from 0 (without any difficulty) to 3 (unable to do), with higher values indicating higher disability. Randomized Set, which included all randomized participants grouped by randomized treatment group. Number of participants analyzed = participants with evaluable data for the outcome measure.

    CDA-IGA is a scale that was created to measure disease severity in participants with skin disease. It is a 5-point scale (0 = clear; 1 = almost clear; 2 = mild; 3 = moderate; 4 = severe) with morphologic descriptors for each score. The CDA-IGA was completed by the Investigator and was used to describe the overall appearance of lesions at a given time point. Data are presented for the number of participants with a CDA-IGA response at Week 26. A response was defined as participants with clear or almost clear skin (score of 0 or 1) who did not have an intercurrent event at or before the relevant timepoint.

    TIS20 was defined as a ≥20-point improvement response on IMACS-TIS. IMACS-TIS is a clinical instrument that encompasses 6 CSMs (physician, patient, extra-muscular global activity, muscle strength, HAQ, and muscle enzyme levels). A Total Improvement Score (TIS: 0–100), was determined by summing scores in each CSM, and was based on the improvement and relative weight of each CSM. Higher scores indicated greater improvement/response. TIS20 is considered a mild improvement score. Randomized Set, which included all randomized participants grouped by randomized treatment group.
