E.1.2 | Term | Systemic sclerosis |
E.1.2 | System Organ Class | 10028395 - Musculoskeletal and connective tissue disorders |
|
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Safety and tolerability of Rituximab on skin and lung fibrosis in patients with Systemic Sclerosis previously treated with intravenous pulse 6-metilprednisolone and Cyclophosphamide |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Patients with age between 18 and 70 years;
2. SSc diagnosis with diffuse cutaneous involvement, accordingly to ACR and Le-Roy criteria;
3. Worsening of skin involvement, evaluated with Rodnan skin score, higher than 10% in the last 2-3 months;
4. Capacity to sign the informed consent;
5. Previous treatment with intravenous pulse 6-metilprednisolone and oral Cyclophosphamide (at least 6 grams);
Enrolled patients should ensure not to intend to get pregnant during the treatment and for 6 months after the last dose of Rituximab and Cyclophoasphamide
|
|
E.4 | Principal exclusion criteria |
1. Severe lung and heart involvement, with dyspnea and signs or symptoms of heart or lung failure (Oxigen saturation lower than 60%, FVC<50%, FE<40%, DLCO<40%)
2. Patients with acute and chronic infections;
3. Hystory of immunodeficiency, tubercolosis or cancer;
4. Pregnancy and feeding;
Moderate or severe renal failure (creatinine clearance <30 ml/min)

E.5 End points |
E.5.1 | Primary end point(s) |
• Rituximab efficacy on skin involvement through Rodnan skin score. We will consider clinically relevant a decrease of skin score higher than 30% compared to initial skin score
• Rituximab efficacy on lung involvement. We will consider clinically relevant an increase higher than 10% for FVC and TLC and/or higher than 15% for DLCO, and/or a decrease of extension of ground glass and honey-combing scores higher of 2 points on lung HRCT
• Safety and tolerability of the drug
Efficacy on arthritis manifestations evaluated with DAS (disease activity score), number of swollen and tender joints, analogic scale for pain.

• Efficacy on patient disability through “health global assessment” and “Health Assessment Questionnarie”.
• Changes of capillaroscopic CSURI score,
• Fibrotic and inflammatory cytokines levels in serum and plasma only in patients that accept this optional part of the study
Entity of cellular infiltrate on skin biopsies before and after therapy ( 6 and 24 month) only in patients that accept this optional part of the study
