The Effects of Botulinum Toxin on Oral Aperture in Patients With Scleroderma
SclerodermaThis study will evaluate the use of botulinum toxin for microstomia (also known as reduced oral aperture) in scleroderma patients. Botox is a neurotoxin that functions as a paralytic by preventing the release of acetylcholine to inhibit muscle contracture and decrease fibrosis by decreasing differentiation of fibroblasts to myofibroblasts, decreasing expression of collagen, and increasing expression of matrix metalloproteinase1-3. The study will include three arms: the temporomandibular joint (TMJ) group who will receive injections of Botox to the masseter, the perioral group who will receive injections of Botox around the lips, and a control group who will receive no treatment for ROA. Outcome measurements will include measurement of oral aperture size through measurement inter-labial distance and between the upper and lower lips and the inter-incisal distance, patient satisfaction via a Skindex16 survey, mouth disability via the Mouth Handicap in Systemic Sclerosis Scale (MHISS), and patient and physician satisfaction using the Visual Analogic Scale (VAS). The maximum number of subjects to be consented for this study is 30. The study is expected to last four months per subject from time of consent to last clinical evaluation. Conditions that may result in a subject exiting the study prior to completion date include non-compliance, withdrawal of consent, or safety concerns such as adverse events as a result of treatment.
Effects of Intensive Aerobic and Muscle Endurance Exercise in Patients With Systemic Sclerosis -...
Systemic SclerosisThe hypothesis is that intensive aerobic and endurance muscle training is safe and beneficial in patients with systemic sclerosis and concurrent interstitial lung disease. The purpose of the study is to examine the effect of an eight week intensive aerobic exercise and muscle endurance training program for patients with systemic sclerosis and 50-100 % of forced vital capacity. A single subject experimental design with repeated systematic measures during a six week A-phase (baseline period) and an eight week B-phase (intervention period) was used. Physical capacity (six minute walk test), aerobic capacity (submaximal treadmill test) and muscle endurance in shoulder and hip flexion (Functional Index 2) are assessed every other week throughout the 14 week study. Activity limitation (Health Assessment Questionnaire), quality of life (Short Form 36), Raynaud, Fatigue and Global Health during the recent week (Visual Analogue Scales) are assessed at weeks 0, 6, 14. The exercise program includes aerobic exercise corresponding to 15 on the Borg RPE scale (strenuous) and muscular endurance training three times/week.
A Clinical Trial of Ambrisentan and Tadalafil in Pulmonary Arterial Hypertension Associated With...
Pulmonary Arterial HypertensionSystemic Sclerosis3 moreThis will be a 36-week, single group, open label study assessing the effects of Tadalafil plus Ambrisentan combination therapy in patients with pulmonary arterial hypertension associated with the scleroderma spectrum of disease (PAH-SSD). Standard outcome measures such as six-minute walk distance (6MWD), New York heart Association (NYHA) classification, and hemodynamic measurements will be assessed, as well as novel functional measures of RV-PV function including the transthoracic echocardiogram parameter tricuspid annular plane systolic ejection (TAPSE), contrast-enhanced cardiac MRI and heart rate variability assessed by Holter monitoring. This design (excluding a placebo arm) was selected for ethical concerns and to provide optimal efficiency and active therapy to all study subjects. It also allows for comparisons between the two monotherapies and with combination therapy.
Effect of Rosuvastatin on Systemic Sclerosis-related Pulmonary Hypertension
Systemic SclerosisAlthough the aetiology of SSc-PAH remains elusive, vascular dysfunction seems to be the initial event and statins through their vasculoprotective effect might be of value in the treatment armamentarium of PAH related to SSc. The aim was to assess the efficacy of rosuvastatin in ameliorating vascular dysfunction and in the management of SSc-related PAH.
Nilotinib in the Treatment of Systemic Sclerosis
Systemic SclerosisA phase IIa open-label single center pilot study to assess the safety and efficacy of Nilotinib in patients with Scleroderma.
Pharmacokinetics of Oral Treprostinil in Patients With Systemic Sclerosis
Systemic SclerosisThis study will assess the pharmacokinetic and safety profile of treprostinil following fixed and escalating doses of treprostinil diethanolamine SR tablets. Open-label, two-part study assessing the pharmacokinetics, safety, and tolerability of oral treprostinil diethanolamine SR. Cohort 1: single 1 mg treprostinil diethanolamine SR dose. Cohort 2: escalating doses of treprostinil diethanolamine SR up to a target dose of 4 mg BID.
Early Therapy of Pulmonary Arterial Hypertension
Pulmonary HypertensionSystemic SclerosisExercise-induced increase of the pulmonary arterial pressure may be an early sign of pulmonary arterial hypertension. It has been shown that patients with normal pulmonary arterial pressure at rest but elevated pulmonary arterial pressure during exercise have a decreased exercise-capacity and may have a worse prognosis compared to patients with normal pulmonary arterial pressure values at rest and during exercise. According to the currently used definition pulmonary hypertension can be diagnosed if the mean pulmonary arterial pressure is higher than 25mmHg at rest or 30mmHg during exercise. In this study patients with a risk for pulmonary arterial hypertension (connective tissue disease) and increased pulmonary arterial pressure values during exercise are receiving a therapy with a dual endothelin receptor antagonist - bosentan, a therapy established for pulmonary arterial hypertension. The therapy effect is than compared to the recorded changes before the introduction of this therapy.
A Study Using The Experimental Drug Called Imatinib (Gleevec) in Subjects With Systemic Sclerosis...
AlveolitisSystemic SclerosisThe purpose of this study is to assess the safety and tolerability of imatinib (gleevec) in subjects who have systemic sclerosis. Imatinib has been approved by the FDA for the treatment of newly diagnosed adult patients with CML (newly diagnosed adult patients and for the treatment of patients with an accelerated phase. Imatinib is also approved for the treatment of patients with a certain type of gastrointestinal cancer (called stromal tumors) but it has not been approved to treat systemic sclerosis. Imatinib works by interfering with an enzyme called tyrosine phosphatase resulting in suppression of the immune system. It als interferes with a protein called platelet derived growth factor receptor (PDGFr) that has been linked to increased fibrosis.
A Study to Evaluate the Safety and Efficacy of Abatacept in Patients With Diffuse Systemic Sclerosis...
SclerodermaDiffuse2 moreSystemic sclerosis (scleroderma) is an autoimmune connective tissue disease that involves the skin and other internal organs for which there are few effective treatment options. We hypothesize that treatment with abatacept, a new therapy recently approved for the treatment of rheumatoid arthritis, may reduce the progression of skin thickening and fibrosis in people with scleroderma.
Efficacy and Safety of Imatinib in Scleroderma
SclerodermaLocalized2 moreIn vitro studies have shown that imatinib 1mM inhibits strongly the growth of cutaneous fibroblasts. The hypothesis is that imatinib inhibits PDGFR which is known to be a potential target for the molecule, as recently also proposed after the discovery of autoantibodies activating the PDGF receptors. Recent data indicate that TGFb is also a potential target of imatinib. Cutaneous scleroderma is characterized by progressive cutaneous fibrosis caused by hyperactive dermal fibroblasts. Since no established treatment for skin sclerosis in scleroderma is currently available. This study will test the safety and efficacy of imatinib in the treatment of patients with scleroderma and severe cutaneous involvement.
