NCT07090226
Scleroderma (SSc) is an autoimmune disease characterized by fibrosis (or collagen deposition) of the skin and internal organs. The extent of skin fibrosis is an important predictor of internal organ complications and increased mortality. Currently a very imprecise, subjective method that varies amongst different doctors for the same patient is used to quantify skin fibrosis in patients, by "pinching" their skin and assessing how thick it is; this is the method used to determine the modified Rodnan skin score (mRSS). A previous plot study was conducted by the investigators to determine if spatial frequency domain imaging (SFDI), a method of light scattering, could be used to measure the collagen content in the skin of SSc patients. This non-painful, noninvasive method takes very little time and the investigators hypothesized that it would be more accurate than the "pinching" method. For that pilot study, patients with various stages of the disease were selected, and SFDI was used to image 6 areas. A forearm skin biopsy was taken for subsequent histopathology analyses of collagen content. The clinical mRSS was assessed at the time of SFDI measurement. Optical property imaging data was analyzed and statistically correlated and analyzed with immunohistochemistry (a method of identifying proteins) of the skin. Preliminary results demonstrated a strong correlation between mRSS and SFDI. Some of the imaging parameters of the SFDI were modified based on the initial results. Initial results demonstrated that the device can detect increases in skin thickness observed in SSc skin.
NCT07326033
Orofacial manifestations and microstomia are a frequent complication in systemic sclerosis (SSc) with a major impact on oral hygiene, dental care and quality of life. Peri-oral injection of allogeneic cultured adipose-derived stromal cells constitutes a promising approach to treat scleroderma-induced mouth fibrosis where no alternative therapy is validated. The aim of this phase 2 study is to compare efficacy and safety of perioral injection of allogeneic cultured adipose-derived stromal cells (AdMSC) versus placebo to improve oro-facial fibrosis in patients with systemic sclerosis.
NCT03508375
Systemic Scleroderma (SCS) is an autoimmune disease characterized by vascular involvement, a dysimmune condition, cutaneous and visceral fibrosis. Interstitial lung disease (ILD) affects 75% of SSc patients and is the leading cause of death in SSc. No diagnostic or prognostic biomarkers of SSc-associated ILD have been validated to date. The search for such a serum biomarker is essential to assess the severity of these patients and to help the therapeutic management. We have shown that soluble fractalkine is elevated in SSc patients, especially in SSc patients with ILD. The fractalkine is both an endothelial adhesion molecule and a chemokine that binds to the CX3CR1 receptor expressed by immune populations. It would thus reflect the vasculopathy and inflammation that lead to the fibrosing pulmonary involvement of this disease. Objectives and means: We aim to perform a low-risk interventional biomedical research which main objective is the quantitative evaluation of soluble fractalkine in SSc patients with ILD in comparison with SSc patients without ILD. This epidemiological, explanatory, analytical, single-center study will comprise three groups: 1 / SSc without ILD (control group in the context of SSc), 2/ SSc with ILD and 3/ patients with idiopathic pulmonary fibrosis (IPF) (control group of the ILD). Secondary objectives are evaluation of: 1 / fractalkine levels in the IPF, 2 / correlations between fractalkine levels and severity of ILD and of SSc disease over time, 3 / correlations between fractalkine and 2 other biomarkers: KL-6 (marker of pulmonary fibrosis) and soluble CD146 (sCD146, marker of vasculopathy), 4 / predictive values of the decline in lung function of these 3 markers.
NCT03629002
The overall objective is to propose a comprehensive analysis of the biological properties of the stromal vascular fraction evaluated in the SCLERADEC 2 clinical trial (n = 15 available) and preserved in the biological collection, compared to healthy donors (n = 10). This characterization will focus on the exploration of the phenotypic and functional characteristics of the main cellular subpopulations present in the stromal vascular fraction of scleroderma patients likely to be associated with a better regenerative vascular or anti-fibrotic activity of the cell therapy product. The main objective will be to validate whether the supposed mechanism of action of this innovative therapy, in relation to the representativity of the endothelial progenitors, carrying the vascular regeneration activity, is preserved in the sclerodermic context. A total of 30 subjects (20 systemic Scleroderma patients and 10 healthy donors) will be included.
NCT00622895
The purpose of the study is to examine the safety and effectiveness of a reduced intensity conditioning regimen and allogeneic bone marrow transplant for people with systemic sclerosis. In an allogeneic bone marrow transplant procedure, bone marrow is taken from a healthy donor and transplanted into the patient. Bone marrow can be donated by a family member or an unrelated donor who is a complete tissue type match. Participants will receive the chemotherapy and low dose radiation conditioning regimen consisting of the following: Fludarabine will be given intravenously for 5 days. Cyclophosphamide will be given intravenously on the first and second day. After completing the fludarabine and cyclophosphamide, patients will receive a single low dose of total body irradiation. The next day, patients will receive the allogeneic bone marrow transplant. On the third and fourth day after the transplant, patients will receive high dose intravenous cyclophosphamide. This is given to help prevent two complications: (1) graft rejection, which occurs when the body's immune system rejects the donor bone marrow, and (2) graft-versus-host disease (GVHD), which is when the donor immune cells attack the patient's normal tissues. On the fifth day after the transplant, patients will start receiving two additional medications: tacrolimus and mycophenolic acid (MPA, Myfortic), to help prevent GVHD. Patients will receive mycophenolic acid for about 5 weeks and tacrolimus for about 6 months. Also beginning on the fifth day after the transplant, patients will receive daily injections of a growth factor called granulocyte-colony stimulating factor (G-CSF), which is a protein that increases the white blood cell count; G-CSF will be continued until the patient's white blood cell count has returned to normal levels. Patients will remain closely monitored either in the outpatient clinic setting or in the hospital for approximately 2-3 months after the transplant, but possibly longer if there are complications. Follow-up study visits will occur at 6 months and then at 1, 2, 3, 4, and 5 years after the transplant. Study researchers will keep track of the patient's medical condition after leaving the transplant center by phone calls or mailings to patients and their doctors once a year for the rest of the study participants' lives.
NCT00522002
To explore the hypothesis that leg ulcers are associated with hypercoagulable states, the CLUE study will evaluate patients with connective tissue disease associated leg ulcers, to identify risk factors (especially hypercoagulability and immunologic characteristics), characterize pathogenesis, predict response to therapy, and assess the impact of lower extremity ulcers on quality of life.
NCT01410903
The purpose of this study is to evaluate source data for the survival and the investigation of the preliminary efficacy of immunoadsorption in patients with severe systemic sclerosis.
NCT01295736
Digital ulcers (DUs) are an expression of the microangiopathy in patients with scleroderma (SSc). DUs lead to pain and impaired hand use. DUs remain a severe complication for many patients and effective therapy remains elusive. In the present study, the investigators propose to evaluate the efficacy of Sildenafil in DUs healing in a randomized double blind control study in SSc patients.
NCT01047072
The purpose of the study is to see how well reduced intensity conditioning followed by a stem cell transplant from a donor (allogeneic) works in treating patients with severe systemic sclerosis. In an allogeneic stem cell transplant procedure, stem cells are taken from a healthy donor and transplanted into the patient. Stem cells can be donated by a family member or an unrelated donor who is a complete tissue type match.
