Rituximab for Treatment of Systemic Sclerosis-Associated Pulmonary Arterial Hypertension (SSc-PAH)...

Systemic Sclerosis-Associated PAH

Systemic sclerosis-associated pulmonary arterial hypertension (SSc-PAH) is a serious, life-threatening manifestation of systemic sclerosis (SSc), an autoimmune disease of the connective tissue characterized by scarring (fibrosis) and atrophy of the skin, joints and tendons, skeletal muscles, and internal organs, and immunological disturbances. One-year survival for patients with SSc-PAH ranges from 50-81%. There is currently no cure for SSc-PAH and treatment is limited to vasodilator therapy used in all forms of PAH. In recent studies, immunotherapy was shown to be effective in treating SSc-interstitial lung disease, another serious, life-threatening manifestation of SSc. In addition, there are compelling pre-clinical data and anecdotal clinical reports that suggest modulation of the immune system may be an effective strategy for treating SSc-PAH. To test this approach, this trial will determine if rituximab, an immunotherapy, has a marked beneficial effect on clinical disease progression, with minimal toxicity, in patients with SSc-PAH when compared to placebo.

Comparison of Therapeutic Regimens for Scleroderma Interstitial Lung Disease (The Scleroderma Lung...

SclerodermaInterstitial Lung Disease

Scleroderma is a rare, long-term autoimmune disease in which normal tissue is replaced with dense, thick fibrous tissue. Normally, the immune system helps defend the body against disease and infection. In people with scleroderma, the immune system triggers fibroblast cells to produce too much of the protein collagen. The extra collagen becomes deposited in the skin and organs, causing hardening and thickening that is similar to the scarring process. Although scleroderma most often affects the skin, it also can affect other parts of the body, including the lungs, and in its most severe forms scleroderma can be life-threatening. Scleroderma-related interstitial lung disease is one example of a life-threatening scleroderma condition. In people with symptomatic scleroderma-related interstitial lung disease, scarring occurs in the delicate lung tissue, compromising lung function. The purpose of this study is to determine whether people with symptomatic scleroderma-related interstitial lung disease experience more respiratory benefits from treatment with a 2-year course of mycophenolate mofetil or treatment with a 1-year course of oral cyclophosphamide.

Imatinib in Systemic Sclerosis

SclerodermaSystemic

Systemic sclerosis (SSc) is an autoimmune disease characterized by fibrosis of the skin and internal organs and widespread vasculopathy. Patients with SSc are classified according to the extent of cutaneous sclerosis: patients with limited SSc have skin thickening of the face, neck, and distal extremities, while those with diffuse SSc have involvement of the trunk, abdomen, and proximal extremities as well. The disease course varies depending on the subtype of SSc. However, common features that result in significant morbidity and mortality, in addition to cutaneous fibrosis, include Raynaud's phenomenon and digital ulcerations, interstitial lung disease (ILD), and pulmonary arterial hypertension (PAH). Current therapeutic options for patients with SSc and these clinical manifestations have shown limited efficacy. Imatinib antagonizes specific tyrosine kinases that mediate fibrotic pathways involved in the pathogenesis of SSc, including c-Abl, a downstream mediator of transforming growth factor (TGF)-beta, and platelet derived growth factor (PDGF) receptors. The efficacy of imatinib has also been reported in the treatment of patients with refractory idiopathic PAH through its effects on vascular remodeling. Based on the mechanism of action and preliminary patient data, we hypothesize that imatinib may be effective in the treatment of the fibrotic and vasculopathic features of patients with SSc. This is an open label pilot study to evaluate the safety and efficacy of imatinib in patients with progressive SSc refractory to other treatment(s). Validated measures of skin thickness and disease activity will be determined over 6-months of therapy and compared with baseline measures.

Rituximab Versus Cyclophosphamide in Connective Tissue Disease-ILD

Interstitial Lung DiseaseScleroderma2 more

Interstitial lung disease (ILD) is characterised by inflammation and scarring of the lung and is the leading cause of death in patients with systemic sclerosis, and contributes significantly to morbidity and mortality in many other connective tissue diseases (CTDs) such as polymyositis/dermatomyositis and mixed connective tissue disease. When ILD is extensive and/or progressive, immunosuppressive medication is often required to stabilize lung disease and alleviate symptoms. Current standard care for CTD associated ILD is extrapolated from studies performed in individuals with systemic sclerosis and comprises low dose corticosteroids and intravenous cyclophosphamide followed by oral azathioprine. In some individuals even this intensive immunosuppression is insufficient to prevent deterioration, and in a significant minority of affected individuals this results in respiratory failure and death. Rituximab has recently been reported as an effective 'rescue therapy' for stabilizing and even improving ILD in this patient group. Based on observations gained from this experience, the investigators believe that rituximab is a potential important alternative to current best therapy for this patient group. This study has therefore been initiated to evaluate the efficacy of rituximab (compared with standard therapy) in patients with progressive CTD related ILD.

Assessment of the Subcutaneous Reinjection of Human Autologous Adipose-derived Stromal Vascular...

Systemic Sclerosis

Systemic sclerosis is an autoimmune disease characterized by skin lesions and visceral responsible for significant morbidity. Microcirculatory disorders and tissue fibrosis are excessive severity of the disease. This condition can affect the hands with a major functional consequence severely impairing the quality of life of patients. Adipose tissue is used in plastic surgery for over a century for the filling of depressions in the skin. In addition to the volume effect, a trophic effect on the surrounding tissue was noted. It is shown that the stromal vascular fraction is responsible for this regenerative effect. In a previous study the investigators have demonstrated in a mouse model that the subcutaneous adipose tissue provides a trophic effect on SSc skin lesions by reducing the fibrosis of the dermis and providing a pro angiogenic. Objectives and means: This is a clinical study evaluating an innovative cell therapy procedure. The objective of this study was to evaluate the effects of injection of autologous stromal vascular fraction of adipose origin according to the system Celution ® (Cytori Therapeutics, Inc.., United Kingdom) in digital in patients with scleroderma cutaneous hands. Eleven patients with scleroderma with the hands will be included in the study. Due to the nature of the orphan disease, a longitudinal study be conducted, where each patient will have own control. The evaluation will be pre and post operative for a period of six months. This evaluation will be based on clinical criteria (trophic balance, functional) and laboratory (capillaroscopy, Doppler ultrasound of the arteries of the forearm, laser-Doppler tissue). Project schedule and implementation phases: The project will run over a period of twelve months. Patients will be followed for a period of six months. Analyzes clinical, paraclinical, and exploitation of results will be achieved over a period of six months. Expected Results: This study will validate the functional and trophic effects of reinjection of autologous stromal vascular fraction of adipose tissue issue on the fingers of patients with scleroderma. Conclusion: This innovative cell therapy could represent an alternative treatment for patients with scleroderma in check, intolerant or insufficiently relieved by medical treatment currently available in the scleroderma hand

Early Treatment of Borderline Pulmonary Arterial Hypertension Associated With Systemic Sclerosis...

Systemic SclerosisPulmonary Hypertension

Trial Design Patients with borderline PAH indicated by borderline mPAP values will be included in this single centre study. This clinical investigation is performed as a Proof-of-Concept (PoC) investigator initiated trial (IIT) using a prospective, randomized, double-blind, parallel group, placebo-controlled, phase IIA clinical study design. On their first visit their medical history will be obtained and physical examination will be conducted. Moreover, an electrocardiogram (ECG), laboratory testing (NT-proBNP, uric acid and other laboratory tests), echocardiography at rest and right heart catheterization will be carried out. If patients have been identified within the last 6 months before screening investigations by right heart catheterization, the measurements are considered valid as baseline investigations and will not be repeated. If patients fulfill the inclusion criteria and still suffer from borderline mPAP values they will be invited to join the study. The clinical investigations will begin within 28 days. The prospective study will comprise a 6 months study period (180 ±2 weeks) plus the screening phase up to 28 days and a follow-up phase of 30 ±7 days.

Oral Manifestations of Systemic Sclerosis

SclerodermaSystemic

Systemic sclerosis (SSc) is a rare multisystem connective-tissue disorder characterized by three major pathological hallmarks: widespread fibrosis, vasculopathy and immunological abnormalities. As all connective tissues can be affected, this condition has multiple effects on the orofacial region. Indeed, the latter is involved in approximately 80% of SSc patients. Oral manifestations have a major impact on quality of life and require specific treatments that should be performed as early as possible. Widening of the periodontal ligament space, that seems to be linked to an increased collagen synthesis, is one of the most common dental radiographic finding. However, this radiologic sign has been mostly studied on two-dimensional radiographs. The investigators have recently described in a patient suffering from SSc the existence of calcifications within the periodontal ligament space using Cone Beam Computed Tomography (CBCT) approach (Jung et al., Oral Surg Oral Med Oral Pathol Oral Radiol 2013). Such calcifications, that have never been observed before, could be part of the phenotypic spectrum of the disease, in particular when dystrophic calcinosis is associated. They could furthermore constitute a specific feature of SSc. However, this radiographic sign requires to be investigated in a largest number of patients. Several cytokines have been implicated in SSc pathogenesis. A recent study has revealed that elevated CXCL4 serum levels correlate with disease complications, suggesting that this molecule could be used as a prognostic biomarker. Increased IL-6 serum levels also correlate with SSc severity. Gingival crevicular fluid can be easily collected from the gingival crevice surrounding the teeth and constitute an indicator of local but also systemic inflammation. Analysis of gingival crevicular fluid cytokine profile could contribute to the identification of specific SSc biomarkers and allow a better comprehension of oral manifestations pathogenesis. The aim of this case-control study is to characterize precisely the oral manifestations associated with SSc within the National Referral Center for Rare Autoimmune Diseases (Strasbourg, France) patient cohort in order to identify specific radiological, clinical and/or biological signs. Some of them could be correlated to the severity or to the prognosis of the disease. To the investigators knowledge it is the first study using tridimensional CBCT approach.
