- Primary Outcome Measures
Name Time Method Number of Participants who Experience an Adverse Event (AE) 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.
Number of Participants who Discontinue due to an AE 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.
Change from Baseline in the Annual Rate of Change in Forced Vital Capacity (FVC) at Week 50 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.
Number of Participants who Experience a Serious Adverse Event (SAE) 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.
- Secondary Outcome Measures
Name Time Method Change from Baseline in FVC at Week 50 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.
Change from Baseline in High-Resolution Computer Tomography (HRCT) Quantitative Interstitial Lung Disease - Whole Lung (QILD-WL) at Week 50 Baseline and Week 50 QILD-WL will be measured as percent lung involvement using HRCT.
Percentage of Participants with an Improvement in the Revised Composite Response Index in Systemic Sclerosis (CRISS) Score at Week 50 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.
Change from Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) at Week 50 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.
Change from Baseline in Living with Pulmonary Fibrosis (L-PF) Quality of Life (QoL) Outcome at Week 50 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.
