Primary Outcome Measures :
  1. The ACR CRISS composite score (0-1) at Week 52 [ Time Frame: Week 52 ]
    The comparison between MT-7117 treatment group and placebo group will be performed. The ACR CRISS exponential algorithm determines the predicted probability of improvement from baseline, incorporating change in mRSS, FVC % predicted, physician and patient global assessments, and HAQ-DI. The outcome is a continuous variable between 0.0 and 1.0 (0 - 100%). A higher score indicates greater improvement.


Secondary Outcome Measures :
  1. Change in Health Assessment Questionnaire Disability Index (HAQ-DI) from baseline up to week 52 [ Time Frame: 52 weeks ]
    To evaluate the efficacy of MT 7117 treatment for up to 52 weeks using the Health Assessment Questionnaire Disability Index (HAQ DI). The Health Assessment Questionnaire Disability Index (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 is 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 was computed as the sum of component set scores and divided by the number of component sets answered. This outcome measure represents the change in mean score from baseline. A negative change from baseline indicates improvement.

  2. Change in percent predicted forced vital capacity (%pFVC) from baseline up to week 52 [ Time Frame: 52 weeks ]
    To evaluate the efficacy of MT-7117 treatment for up to 52 weeks on pulmonary function as measured by percent predicted forced vital capacity (%pFVC)

  3. Change in Patient Global Assessment from baseline up to week 52 [ Time Frame: 52 weeks ]
    To evaluate the efficacy of MT-7117 treatment for up to 52 weeks using the Patient Global Assessment

  4. Change in Physician Global Assessment from baseline up to week 52 [ Time Frame: 52 weeks ]
    To evaluate the efficacy of MT-7117 treatment for up to 52 weeks using the Physician Global Assessment

  5. Change in modified Rodnan Skin Score (mRSS) from baseline from baseline up to week 52 [ Time Frame: 52 weeks ]
    To evaluate the efficacy of MT-7117 treatment for up to 52 weeks using the modified Rodnan Skin Score (mRSS). mRSS evaluates a subject's skin thickness which will be assessed by palpation and rated using an mRSS that ranges from 0 (normal) to 3 (severe skin thickening) across 17 different body sites. The total score is the sum of the individual skin scores from all of these sites and ranges from 0 to 51 units.

  6. ACR CRISS Score up to Week 39 [ Time Frame: 39 weeks ]
    To evaluate the efficacy of MT 7117 treatment for up to 39 weeks using the ACR CRISS Score. The ACR CRISS exponential algorithm determines the predicted probability of improvement from baseline, incorporating change in mRSS, FVC % predicted, physician and patient global assessments, and HAQ-DI. The outcome is a continuous variable between 0.0 and 1.0 (0 - 100%). A higher score indicates greater improvement.

  7. ACR CRISS score responder (CRISS>=0.6) from baseline up to week 52 [ Time Frame: 52 weeks ]
    To evaluate the efficacy of MT-7117 treatment for up to 52 weeks using CRISS Score. Subjects with CRISS score is >=0.60 are considered improved, while subjects with CRISS score < 0.60 are considered not improved.
