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   44335   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 ).

    General information about the trial
    Main objective of the trial
    To evaluate the efficacy of MT-7117 treatment in participants with diffuse cutaneous systemic sclerosis (dcSSc) using the American College of Rheumatology Composite Response Index in Diffuse Systemic Sclerosis (ACR CRISS) at Week 52.
    Protection of trial subjects
    The study was conducted in accordance with the 2013 (Fortaleza) revision of the 1964 Declaration of Helsinki, Good Clinical Practice (GCP) as required by the International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) guidelines, applicable regional and local legislation, and standard operating procedures (SOPs) in place at Mitsubishi Tanabe Pharma America Inc. (MTPA). Prior to undergoing any study-specific procedure, all legally competent participants were required to provide consent in writing to participate in the study. An Informed Consent Form (ICF) was given to each participants, which contained all regulatory, ICH and data protection requirements, as applicable, in language understandable to the participant. If a participant was legally incompetent, the enrollment of such a participant was required to be in accordance with all applicable laws, and consent sought by the Investigator from the participant’s legally authorized representative. Either the Investigator or a designated person, qualified to meet any applicable local regulations, who was equally knowledgeable about the study explained the aims, methods, anticipated benefits and potential hazards of the study and any discomfort it could entail. A corresponding written explanation was also provided, and the subject allowed sufficient time to consider the study information. Clinical monitoring was conducted to confirm the ethical conduct of the study at the investigational site(s).

    ACR CRISS Composite Score at Week 52
    End point description
    The ACR CRISS is a composite endpoint that calculates probability of improvement from baseline, incorporating change in modified Rodnan Skin Score (mRSS), percentage predicted forced vital capacity (%pFVC), physician and patient global assessments, and Health Assessment Questionnaire Disability Index (HAQ-DI). The outcome was a continuous variable between 0.0 and 1.0 with higher score indicating improvement in symptoms. A higher score indicated greater improvement. An ACR CRISS score of 0.60 or greater indicated that a participant improved on treatment and a score of less than 0.60 suggested that a participant had not improved. Intent-to-treat (ITT) population: Included all randomized participants who received at least 1 dose of study drug.

    End point title
    Change in HAQ-DI from Baseline at Weeks 16, 26, 39, and 52
    End point description
    The HAQ-DI is a self-administered instrument consists of 20 questions referring to eight component sets consisting of dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities. Each item was scored on a 4-point scale from 0 to 3: 0 = Without any difficulty; 1 = With some difficulty; 2 = With much difficulty; 3 = Unable to do. Overall score, ranging from 0 to 3, was calculated as the sum of component set scores and divided by the number of component sets answered. A negative change from baseline indicated improvement. ITT population: Included all randomized participants who received at least 1 dose of study drug.

    Change in Physician Global Assessment (PhGA) from Baseline at Weeks 16, 26, 39, and 52
    End point description
    The PhGA was used to assess the physician’s rating of overall health of the participant. Physicians rated the perceived health of the participant on an 11-point scale from 0 (excellent) to 10 (extremely poor). A negative change from baseline indicated improvement in symptoms. ITT population: Included all randomized participants who received at least 1 dose of study drug.

    mRSS evaluated a participant's skin thickness which was assessed by palpation and rated on a scale ranged from 0 (normal) to 3 (severe skin thickening) across 17 different body sites. The total score was the sum of the individual skin scores from all of these sites and ranged from 0 to 51 units. A negative change from baseline indicated improvement in skin symptoms.

    ACR CRISS Score at Weeks 16, 26, and 39
    End point description
    The ACR CRISS is a composite endpoint that calculates probability of improvement from baseline, incorporating change in modified Rodnan Skin Score (mRSS), percentage predicted forced vital capacity (%pFVC), physician and patient global assessments, and Health Assessment Questionnaire Disability Index (HAQ-DI). The outcome was a continuous variable between 0.0 and 1.0 with higher score indicating improvement in symptoms. A higher score indicated greater improvement. An ACR CRISS score of 0.60 or greater indicated that a participant improved on treatment and a score of less than 0.60 suggested that a participant had not improved. Intent-to-treat (ITT) population: Included all randomized participants who received at least 1 dose of study drug.
