Experimental: ST1571
Participants received ST1571 100 mg tablets, orally, once daily.
Initiated at an oral dose of 200 mg/day for 4 weeks then titrated up to 400 mg/day for 2 weeks followed by 600 mg/day until Week 24, if well tolerated.

Primary Outcome Measures
Primary Outcome Measures

Measure Description |
Time Frame |
|---|---|---|
|
Change From Baseline in Modified Rodnan Skin Score (MRSS) at Each Time Point of Analysis
Time Frame: Baseline, Weeks 2, 4, 6, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and Week 48/End of Study (EOS)
|
The efficacy of oral STI571 in participants with systemic sclerosis is defined by an improvement in MRSS.
Skin thickness was assessed clinically in each of 17 body areas and scored using a 0-3 scale, where 0= normal, 1= mild thickness, 2= moderate thickness, and 3= severe thickness (maximum score 51).
A higher score indicates greater severity of the disease.

Baseline, Weeks 2, 4, 6, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and Week 48/End of Study (EOS)
|
|
Number of Participants With Adverse Events (AE's) and Serious Adverse Events (SAE's)
Time Frame: Baseline to Week 48/EOS
|
An AE is the appearance or worsening of any undesirable sign, symptom, or medical condition occurring after starting the study drug even if the event is not considered to be related to the study drug.
An SAE is defined as an event that is fatal or life-threatening, results in persistent or significant disability/incapacity, constitutes a congenital anomaly/birth defect, requires inpatient hospitalization or prolongation of existing hospitalization, is medically significant, i.e., defined as an event that jeopardizes the patient or may require medical or surgical intervention to prevent one of the outcomes listed above.

Time Frame |

Number of Participants With Non-response, Partial Response, Complete Response, and Remission Assessed by MRSS Values
Time Frame: Weeks 2, 4, 6, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and Week 48/End of Study (EOS)
|
The following MRSS categories were calculated for up to Week 48: Non-response: a reduction in MRSS <25%, Partial response: a reduction in MRSS between 25-<50%, Complete response: a reduction in MRSS between 50-<80%, Remission: a reduction in MRSS ≥80%.
|
Weeks 2, 4, 6, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and Week 48/End of Study (EOS)
