Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare the onset of a SSc after 5 years in patients with specific dysimmunity and RP treated either with clopidogrel or with placebo.;Secondary Objective: - To compare after 2 and 5 years the onset of a skin fibrosis in patients with specific dysimmunity and RP treated either with clopidogrel or with placebo. - To compare after 2 and 5 years the extent of skin fibrosis in patients with specific dysimmunity and RP treated either with clopidogrel or with placebo. - To compare after 2 and 5 years the risk of degradation of the Cochin Hand Function Scale in patients with specific dysimmunity and RP treated either with clopidogrel or with placebo. - Assessment of clinical, demographic, biologic or capillaroscopic prognosis factors associated with a higher risk to develop an SSc when presenting with specific dysimmunity and RP.;Primary end point(s): Occurrence of SSc at 5 years according to ACR / EULAR 2013 criteria in the two randomization groups;Timepoint(s) of evaluation of this end point: 60 months after baseline | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Frequency of occurrence of cutaneous fibrosis (sclerodactyly or other affected area) clinically assessed by at least 2 independent investigators in the two randomization groups - Mean of modified Rodman skin score in the two randomization groups - Mean of Cochin Hand Function Scale in the two randomization groups - Demographic (sex, age, environmental factors), clinical (associated diseases, history), biological, capillaroscopic criteria in the two randomization groups ;Timepoint(s) of evaluation of this end point: 60 months after baseline | — |
