Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants Who Experience Grade 3 or Higher Adverse Events That Occur at or Before Week 24
Time Frame: 24 weeks
|
Primary outcome is met if any participants experience a grade 3 or higher event prior to Week 24. A grade 3 AE would constitute as "severe". Grading was following using CTCAE v 4.03. Note that the planned statistical analysis (Fisher's exact test) could not be performed because there were no events. |

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Grade 3 (Severe) or Higher Adverse Events That Occur Throughout the Study
Time Frame: Week 12, 24, 36, and 48
|
Grade 3 or higher adverse events (AEs) assessed throughout the study ( 48 weeks). A grade 3 AE would constitute as "severe". Grading was following using CTCAE v 4.03. Note that the planned statistical analysis (calculation of rate ratio and 90% CI) could not be performed at Weeks 12 and 24 due to no events, and could not be performed at Week 36 because there were no events in the placebo group (denominator). |
Week 12, 24, 36, and 48
|
Number of Grade 2 (Moderate) or Higher Adverse Events That Occur Throughout the Study
Time Frame: Week: 12, 24, 36, and 48
|
Grade 2 or higher assessed 12 weeks apart.
Grade 2 AEs are determined as " moderate".
Grading was performed following CTCAE v 4.03 guidance.
|
Week: 12, 24, 36, and 48
|
Number of Adverse Events of Special Interest (AESI) Throughout the Study
Time Frame: Weeks 12, 24, 36 and 48
|
AESI are pre-defined adverse events as indicated in the protocol. They include: infections, stomach perforations, malignancy, herpes zoster and lab abnormalities. Note that the planned statistical analysis (calculation of rate ratio and 90% CI) could not be performed at Weeks 12 and 24 because there were no events in placebo group (denominator). |
Weeks 12, 24, 36 and 48
|
Change in Modified Rodnan Skin Score (mRSS)
Time Frame: Change from Baseline at weeks: 12, 24, 36, and 48
|
The Modified Rodnan Skin Score (mRSS) is a measure of skin thickness.
Skin thickness in 17 anatomic areas was rated on a 0-3 scale and scores are summed to obtain the mRSS (range from 0 - 51), with higher mRSS scores indicating worse disease activity
|
Change from Baseline at weeks: 12, 24, 36, and 48
|
Provisional American College of Rheumatology Combined Response Index (CRISS) Systemic Sclerosis
Time Frame: Week:12, 24, and 48
|
CRISS components included the following domains: modified Rodnan skin score, forced vital capacity percent predicted, Physician Global Assessment, Patient Global Assessment, and Health Assessment Questionnaire Disability-Index.
An algorithm determines the predicted probability of improvement from baseline by incorporating change in the mRSS, FVC percent predicted, Physician and Patient Global Assessments, and HAQ-DI.
The outcome is a continuous variable between 0.0 and 1.0 (0 - 100%).
A cut-off at 0.6 in the predicted probability of being improved has yielded the smallest misclassification error.
Subjects are not considered improved if, between Visit 1 and 6, they develop new: 1) renal crisis; 2) decline in FVC% predicted by 15% (relative) from baseline and confirmed after 1 month; or 3) left ventricular failure (systolic ejection fraction < 45%) or pulmonary artery hypertension.
Higher CRISS scores indicates improvement.
