Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants who Experience an Adverse Event (AE)
Time Frame: Up to Week 50
An AE is any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. The number of participants who experience an AE will be reported.
Up to Week 50
Number of Participants who Experience a Serious Adverse Event (SAE)
Time Frame: Up to Week 50
An AE is any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. The number of participants who experience an SAE will be reported.
Up to Week 50
Number of Participants who Discontinue due to an AE
Time Frame: Up to Week 50
An AE is any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. The number of participants who discontinue due to an AE will be reported.
Up to Week 50
Change from Baseline in the Annual Rate of Change in Forced Vital Capacity (FVC) at Week 50
Time Frame: Baseline and up to Week 50
FVC, as measured in milliliters by spirometry, is the amount of air forcibly exhaled from the lungs after taking the deepest breath possible.
Baseline and up to Week 50

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change from Baseline in FVC at Week 50
Time Frame: Baseline and Week 50
FVC, as measured in milliliters by spirometry, is the amount of air forcibly exhaled from the lungs after taking the deepest breath possible.
Baseline and Week 50
Change from Baseline in High-Resolution Computer Tomography (HRCT) Quantitative Interstitial Lung Disease - Whole Lung (QILD-WL) at Week 50
Time Frame: Baseline and Week 50
QILD-WL will be measured as percent lung involvement using HRCT.
Baseline and Week 50
Percentage of Participants with an Improvement in the Revised Composite Response Index in Systemic Sclerosis (CRISS) Score at Week 50
Time Frame: Baseline and Week 50
The Revised CRISS is a two-step process designed to evaluate the likelihood of improvement in early SSc. The first step assesses worsening or incident cases of internal organ involvement (scleroderma renal crisis, pulmonary arterial hypertension, congestive heart failure, ILD, severe gastrointestinal dysmotility requiring parenteral or enteral nutrition, and digital ischemia requiring hospitalization, gangrene, or amputation). The second step assesses changes from baseline in five core set measures: modified Rodnan skin score (mRSS), percent predicted forced vital capacity (FVC%), health assessment questionnaire-disability index (HAQ-DI), patient (PGA), and physician (PhGA) global assessments.
Baseline and Week 50
Change from Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) at Week 50
Time Frame: Baseline and Week 50
HAQ is an instrument to assess physical function. It consists of 20 questions, covering eight types of activities. For each question, scores range from 0 to 3 (0 = without any difficulty; 1 = with some difficulty; 2 = with much difficulty or with assistance; 3 = unable to do). HAQ Disability Index (HAQ-DI) score is the average of the highest score in each of the eight categories.
Baseline and Week 50
Change from Baseline in Living with Pulmonary Fibrosis (L-PF) Quality of Life (QoL) Outcome at Week 50
Time Frame: Baseline and Week 50
The L-PF is a questionnaire designed to assess the quality of life of patients with pulmonary fibrosis. It contains 44 questions (items) split into two modules, 23 which assess symptoms (including shortness of breath, cough, and fatigue) and 21 which assess impacts to quality of life. Individual items are scored on a 5-point scale (0 = Not at All to 4 = Extremely). Overall scores range from 0 to 100 with higher scores indicating a greater impairment.
Baseline and Week 50
