Phase I/II Randomized Controlled Trial of Umbilical Cord-derived mesenChymAl stRomal cElls in Systemic Sclerosis

The purpose of this study is to test the safety and efficacy of Umbilical Cord-derived Mesenchymal Stromal Cells (UCMSC) for the treatment of Systemic Sclerosis (SSc).

Bevonási feltételek: SSc according to American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) 2103 classification criteria for systemic sclerosis; Severe disease defined as:; disease duration of 2 years or less with an mRss of > 20 and (ESR > 25 mm and/or hemoglobin < 11 g/dL, not explained by other causes than SSc), or ii) mRss >15 without any restriction as to disease duration plus at least one major organ involvement as defined by: a) respiratory involvement consisting of lung diffusion capacity for carbon monoxide (DLCO) and/or forced vital capacity (FVC) < 80% predicted and evidence of interstitial lung disease (chest X-ray and/or high resolution computed tomography (HRCT) scan); b) renal involvement consisting of past renal crisis and/or stage 2 or 3 chronic kidney disease (glomerular filtration rate between 30-89 mL/min) not explained by other causes than SSc; c) cardiac involvement consisting of reversible congestive heart failure, atrial or ventricular rhythm disturbances such as recurrent episodes of atrial fibrillation or flutter, recurrent atrial paroxysmal tachycardia, conduction abnormalities (2nd or 3rd degree atrioventricular block), and/or mild to moderate pericardial effusion. All causes of organ involvement should be attributed to SSc; Inadequate response (determined by patient and physician judgement) or adverse events necessitating discontinuation of standard therapy (usually consisting of methotrexate 25 mg subcutaneous (or as tolerated) per week and/or mycophenolate mofetil 2-3 gm/d (or as tolerated) for at least 3 months; Ineligibility or unwillingness to undergo autologous hematopoietic stem cell transplant.

Kizáró feltételek: Concurrent neoplasms or myelodysplasia; Severe concomitant psychiatric disorder; Concurrent enrolment in any other protocol using an investigational drug; Uncontrolled hypertension; Uncontrolled acute or chronic infection (HIV, HTLV-1/2 (Human T-lymphotropic virus), hepatitis B surface Ag positive, hepatitis C positive) or high risk thereof; History of poor compliance; Life-threatening end-organ damage defined as:; FVC < 45% and/or DLCO (corrected for hemoglobin) < 30% predicted; Left ventricular ejection fraction < 40% by cardiac echocardiography; Pulmonary hypertension with baseline resting systolic pulmonary arterial pressures > 50 mmHg by cardiac echocardiography, or mean pulmonary artery pressure > 25 mmHg (and pulmonary wedge pressure < 15 mmHg) on right heart catheterization; stage 4 or more chronic kidney disease (glomerular filtration rate < 30 ml/min); Liver failure defined as an abnormal transaminase level (aspartate aminotransferase (ASAT), alanine aminotransaminase (ALAT) > 3 normal) unless related to activity of the disease; Bone marrow insufficiency defined as neutropenia < 0.5 x 109 cell/L, thrombocytopenia < 30 x 109 cell/L, anemia < 8g/dL, CD4+ T lymphopenia < 200 x 106 cell/L due to other diseases than SSc (CD4 - cluster of differentiation 4); Age < 18 years; Pregnancy or unwillingness to use adequate contraception; Significant malnutrition with BMI < 18 kg/m2; Inability to provide informed consent.
