Exclusion criteria
Exclusion criteria: 1.Has a history or presence of rheumatic autoimmune diseases other than dcSSc unless the dominant features of the current disease are from dcSSc, as determined by the Investigator after discussion with the Medical Monitor. 2.Has a pulmonary disease with FVC = 50% of predicted at time of screening. 3.Has a diagnosis of clinically significant resting pulmonary hypertension (if exceeding estimated right ventricular systolic pressure of > 40 mmHg estimated by transthoracic echocardiography [unless the right heart catheterization is normal within the last 6 months] or mean pulmonary artery pressure > 30 mmHg as measured by right heart catheterization) and requires treatment with more than one oral medication. 4.Has a cardiac abnormality such as left ventricular failure with ejection fraction 1.5 × ULN at screening 10. Has a history or presence of clinically significant disease not relatedto SSc [neurologic, renal, endocrine, gastrointestinal cardiovascular, hepatic, dermatologic, hematological, musculoskeletal, genitourinary, thromboembolic, advanced arteriosclerosis, hyperthyroidism, moderate to severe hypertension, immunologic disease, pulmonary (e.g., uncontrolled asthma, emphysema, chronic obstructive pulmonary disease) or any other disorder] as determined by the Investigator at screening 11. Has a history or presence of serious or clinically significant (as judged by the Investigator) psychiatric disorder including but not limited to, anxiety disorder, depression, and bipolar disorder that may make a subject unlikely or unable to complete the study or comply with study procedures and requirements, impact the subject's ability to participate in the study and/or interfere with the study evaluation and/or safety of the subject 12. Has any clinically significant disease or laboratory abnormality judged to be clinically significant by the Investigator and which may interfere with the study evaluation and/or safety of the subject at screening. Laboratory abnormalities include but not limited to any of the followings: Hemoglobin < 9 g/dL; WBC < 3,000/mm3 (< 3 x 10^9/L); platelets < 100,000/mm3 (<100 x 10^9/L) 13.

Has a history of positive human immunodeficiency virus (HIV) 15. Has a history of melanoma, familial melanoma (defined as having 2 or more first-degree relatives

| Main Objective: To evaluate the efficacy of MT-7117 treatment in subjects with diffuse cutaneous systemic sclerosis (dcSSc) using the American College of Rheumatology Composite Response Index in Diffuse Systemic Sclerosis (ACR CRISS) at Week 52.;Secondary Objective: •To evaluate the efficacy of MT-7117 treatment for up to 52 weeks using patient-reported outcomes (PROs) as measured by the Health Assessment Questionnaire Disability Index (HAQ-DI) and Patient Global Assessment. •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). •To evaluate the efficacy of MT-7117 treatment for up to 52 weeks using the Physician Global Assessment. •To evaluate the efficacy of MT-7117 treatment for up to 52 weeks using the modified Rodnan Skin Score (mRSS). •To evaluate ACR CRISS at Weeks 16, 26, and 39. •To evaluate ACR CRISS Score improvement proportion up to 52 weeks.;Primary end point(s): The American College of Rheumatology Composite Response Index in Diffuse Systemic Sclerosis (ACR CRISS) composite score (0-1) ;Timepoint(s) of evaluation of this end point: at week 52 | — |

| Secondary end point(s): Secondary endpoint •Change in HAQ-DI from baseline at Weeks 16, 26, 39, and 52. •Change in Patient Global Assessment from baseline at Weeks 16, 26, 39, and 52. •Change in percent predicted forced vital capacity (%pFVC) from baseline at Weeks 16, 26, 39, and 52. •Change in Physician Global Assessment from baseline at Weeks 16, 26, 39, and 52. •Change in mRSS from baseline at Weeks 16, 26, 39, and 52. •ACR CRISS Score at Weeks 16, 26, and 39. •ACR CRISS Score improvement at Weeks 16, 26, 39 and 52: Proportion of subjects with 25% improvement in mRSS, HAQ-DI, Patient Global Assessment, Physician Global Assessment, or = 5% improvement in FVC for at least 3 of the 5 ACR CRISS measures. •ACR CRISS score responder (CRISS = 0.6) at Weeks 16, 26, 39, and 52. Safety Endpoint(s) •Treatment-emergent adverse events ([TEAEs] including serious adverse events [SAEs], adverse events leading to withdrawal, and adverse events of special interest [AESIs]). •Physical examination. •Vital signs (blood pressure, pulse rate, respiratory rate, and body temperature). •Clinical laboratory examinations (hematology, coagulation, biochemistry, and urinalysis), including liver function markers (ALT, AST, gamma glutamyl transpeptidase [GGT], ALP, direct and total bilirubin). •12-lead electrocardiogram (ECG). •Nevi (Melanocytic Lesions) appearance (assessed by a dermatologist or other qualified site staff). Any nevi (Melanocytic Lesions) undergoing change of clinical concern during active treatment will be biopsied for follow-up and evaluated by a central pathology laboratory.
