Primary Outcome Measures :
  1. CDASI Activity Score [ Time Frame: Change from baseline activitly, (DAY 1) score at week 12 ]

    The Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI), a skin-based outcome measure, was developed to systematically assess the extent of cutaneous disease in patients with DM.

    The CDASI scale is a validated DM-specific instrument designed to capture the extent of cutaneous disease. Disease involvement in 15 different anatomical locations is rated using three activity (erythema, scale, erosion/ulceration) and two damage (poikiloderma, calcinosis) measures. The presence and severity of Gottron's papules, periungual changes and alopecia are also captured. The resulting activity and damage scores range from 0 to 100 and 0 to 32, respectively. Higher scores indicate greater disease severity.

  2. Treatment emergent adverse events and serious adverse events during the study. [ Time Frame: Baseline through Week 12 ]
    Incidence of treatment emergent adverse events (AEs) and serious adverse events (SAE) occurring in DM participants

  3. Clinically significant laboratory abnormalities [ Time Frame: Baseline through Week 12 ]
    Incidence of clinically significant laboratory abnormalities occurring in DM participants.

  4. Clinically significant changes in participants vital signs [ Time Frame: Baseline through week 12 ]
    Incidence of clinically significant changes in vital signs in DM participants.

  5. Clinically significant changes in ECG readings [ Time Frame: Baseline through week 12 ]
    Incidence of clinically significant ECG changes in DM participants.

Secondary Outcome Measures :
  1. CDASI Activity Scores [ Time Frame: Baseline, (DAY 1) - week 12 ]
    Absolute values and change from baseline CDASI activity score through week 12

  2. CDASI Damage score [ Time Frame: Baseline, (DAY 1) - week 12 ]
    Absolute values and change from baseline CDASI Damage Score through week 12

  3. Total Improvement Score (TIS) [ Time Frame: Baseline, (DAY 1) - week 12 ]
    There are 6 core set measures that comprise the total improvement score. These components are the physician global activity assessment, the patient global activity assessment, MMT 8 score, HAQ-DI score, the myositis disease activity assessment tool, (MDAAT), and the participant's most elevated muscle enzymes. The total improvement score is the sum of all 6 improvement scores associated with the change in each core set measure
