- Primary Outcome Measures
Name Time Method Percentage of Participants With Treatment-related Adverse Events (AEs) and Serious Adverse Events (SAEs) Week 52 An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/...
Change From Baseline in Modified Rodnan Skin Score (mRSS) at Week 48 Baseline, Week 48 Skin thickness was assessed by the mRSS. The mRSS was rated with scores ranging from 0 (normal) to 3 (severe skin thickening) across 17 different sites. The total score was the sum of the individual skin scores in the 17 body areas (e.g., face, hands, fingers; proximal area of the arms, distal area of the arms, thorax, abdomen; proximal area of the legs, and...

The mRSS was rated with scores ranging from 0 (normal) to 3 (severe skin thickening) across 17 different sites. The total score was the sum of the individual skin scores in the 17 body areas (e.g., face, hands, fingers; proximal area of the arms, distal area of the arms, thorax, abdomen; proximal area of the legs, and...

FVC is the maximum amount of air exhaled from the lungs after taking the deepest breath possible. Negative change in FVC percent predicted indicates worsen...
Change From Baseline in Physician's Global Assessment at Week 24 and Week 48 Baseline, Week 24 and 48 This assessment represents the physician's assessment of the patient's current disease activity on a 0 (excellent) -10 (extremely poor) Likert scale. Higher score means worse outcome.

Change From Baseline in Diffusing Capacity of the Lungs for Carbon Monoxide (DLCO) Percent Predicted (Corrected For Hemoglobin) at Week 24 and Week 48 Week 24 and 48 Diffusing capacity of the lungs for carbon monoxide (DLCO) measures how much oxygen travels from the alveoli of the lungs to the blood stream. It is used to determine the severity of lung disease. DLCO for a given individual is compared to reference or predicted values.
Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) Score at Week 24 and Week 48 Baseline, Week 24 and 48 The HAQ-DI is a composite measure from which a 'Standard Disability Index' score can be computed to assess a patient's disability level. Generally, a score of 0-1 represents mild to moderate difficulty, 1-2 moderate to severe disability and 2-3 severe to very severe disability. The HAQ-DI comprises 20 items that assess patient abilities across 8 functional a...
American College of Rheumatology Composite Response Index for Systemic Sclerosis (ACR-CRISS) and Revised ACR-CRISS at Week 24 and 48 Week 24 and 48 CRISS forms a composite response index consisting of SSc-related organ involvement and the following five variables: mRSS, FVC percent predicted, physician's and patient's global assessments, and HAQ-DI score. The resulting index is a 2-step process that captures clinically meaningful worsening of internal organ involvement and the core variables that show c...
Change From Baseline in Patient's Global Assessment at Week 24 and Week 48 Baseline, Week 24 and 48 Patient global assessment for overall disease represents the patient's assessment of the patient's global scleroderma on a 0 (excellent) -10 (extremely poor) Likert scale. Higher score means worse outcome.
Change From Baseline in Short Form-36 (SF-36) Questionnaire at Week 24 and Week 48 Baseline, Week 24 and 48 The Short Form 36 (SF-36) is a validated 36 item questionnaire which measures quality of life across eight domains: physical functioning, role limitations due to physical health, role limitations due to emotional problems, energy/fatigue, emotional well-being, social functioning, pain, general health.
