Aandoening
To evaluate the safety and efficacy of anti-CD20 therapy with respect to:
- Clinical and laboratory adverse events, as measured every three months.
- Survival and prevention of major organ failure (referred to as ¡¥event-free survival¡¦ which is considered the primary endpoint).
- Impact on skin thickening, visceral involvement, functional status, and quality of life

Uitkomstmaten
Primaire uitkomstmaten
1. Treatment related mortality is defined as any death during the study period that cannot be attributed to progression of the disease according to the consensus opinion.<br>
2. Treatment toxicity will be assessed using WHO toxicity parameters (expressed as maximum grade toxicity per organ system) (Appendix) in consecutive 3-month periods following randomization.<br>
3. Efficacy will be assessed as progression-free survival, defined as the time in days since the day of randomization until any of the following changes from baseline has been documented at two consecutive 3-month evaluations: <br>
- death<br>
- „d 10% drop in (F)VC and/or „d 15% drop in DLCO (of predicted values)<br>
- „d 15% drop in LVEF by MUGA<br>
- „d 15% drop in body weight<br>
- „d 30% drop in creatinine clearance<br>
- „d 30% increase in Modified Rodnan skin score<br>
- „d 0.5 increase in SHAQ <br> <br>
Changes during the study period (from baseline until completion of 2 years follow-up) in the following parameters : <br>
- Modified Rodnan Skin score<br>
- (F)VC and DLCO<br>
- LVEF<br>
- Weight (Kg) <br>
- SF-36<br>
- EuroQol (EQ-5D)<br>
- gas (pO2, pCO2, p(A-a)O2) at room air<br>
Doel van het onderzoek
In view of the poor prognosis of SSc, the presumed autoimmune origin, and the lack of available therapies, this disease is considered suitable for initial investigation of the tolerability and efficacy of anti B-cell therapy. In literature, there is evidence for a role for B cells in the pathogenesis of scleroderma.
The need remains for other safe alternative treatment strategies in systemic scleroderma and the need for information to test whether a novel approach (B cell depletion) is suitable for treatment.

Onderzoeksproduct en/of interventie
This investigation is a placebo-controlled randomized double blinded single-center phase II study, administering intravaneously monoclonal anti-CD20 antibody or placebo together with a corticosteroid regimen consisting of methylprednisolone 100 mg IV 30 minutes prior to study drug infusion in patients with systemic sclerosis.
