Active clinical trials for "Dermatomyositis"

The aim of this study is to investigate the efficacy and safety of abatacept in patients with Dermatomyositis (DM) and polymyositis (PM) refractory to conventional treatment using a randomised trial design with delayed start in one arm. Abatacept will be administered intravenously to participants at a dose based on body weight at the screening visit followed by six follow-up treatments (Active treatment arm). Abatacept will also be administered intravenously to participants at a dose based on body weight starting at 3 months followed by six follow-up treatments (Delayed-onset treatment arm). The International Myositis Assessment and Clinical Studies Group (IMACS) preliminary definition of improvement (DOI) will be used for assessment.

The purpose of this multi-center pilot study is to determine if the drug tocilizumab (Actemra) is effective in the treatment of patients with refractory adult polymyositis (PM) and dermatomyositis (DM).

To investigate the effect of the interleukin-1 (IL-1) blocking agent, anakinra, in patients with treatment-resistant inflammatory myopathies. Patients and methods: Fifteen patients with refractory polymyositis (PM), dermatomyositis (DM), or inclusion body myositis (IBM) were treated with 100 mg anakinra subcutaneously per day during 12 months. Outcome measures included myositis disease activity score with improvement defined according to The International Myositis Assessment and Clinical Studies Group (IMACS) and for muscle performance the functional index of myositis (FI). In addition repeat muscle biopsies were performed

Juvenile dermatomyositis (JDM) is a connective tissue disease that causes skin rash and weak muscles in children. The purpose of this study is to measure the absorption of oral prednisolone and intravenous (IV) methylprednisolone and to determine levels of disease activity indicators in the blood. These levels will be compared to see if there are patterns specific to active and less active JDM.

"This is a Phase 2 randomized, double-blind, placebo-controlled, crossover, multicenter study to evaluate the safety, tolerability, efficacy, Pharmacokinetics (PK) and Pharmacodynamics (PD) of treatment with KZR-616 in patients with active Polymyositis (PM) or Dermatomyositis (DM). Patients will be evaluated for eligibility during the Screening Period. Eligible patients will be randomized 1:1 to Arm A or Arm B of the study. During the 32-week treatment period, patients will receive study drug subcutaneously (SC) once weekly with 2 treatment periods of 16 weeks each. This study will be conducted on an outpatient basis.

The purpose of this study is to obtain preliminary data regarding the safety and efficacy of Janus kinase (JAK) inhibitor, tofacitinib, in adults with active, treatment-refractory dermatomyositis.

Therapeutical trial in patients with idiopathic polymyositis (PM) and dermatomyositis (DM) is proposed. The study will investigate the safety and efficacy of combined methotrexate (MTX) + glucocorticoids (GC) treatment compared with GC alone. This will be a randomised, open-label, assessor-blind, international multicenter trial, performed in several European centres interested in research on inflammatory myopathies (IIM). A total number of 50 patients with PM/DM will be randomised into two groups (1: MTX+ GC and 2: GC only). Patients will be equally distributed between the two groups providing 25 patients per treatment arm. The randomisation will be based on random numbers generated by a computer program. After being enrolled in the study, the patients will receive 12 months of therapy followed by a 12-month follow-up period. The primary endpoint is the total dose of GC ( in mg/kg weight), which will be administered for 12 months between baseline and the end of treatment. There are several of secondary objectives, which will be pursued during and after the trial. Disease activity and damage will be prospectively assessed by tools for myositis disease activity (MYOACT and MITAX) and for myositis damage (MYODAM and MDI), global assessment of activity and damage by patients and by physician, muscle endurance, muscle strength by manual muscle testing, enzyme levels, GC related side effects, functional ability measured by HAQ, quality of life by SF-36, and number of patients with treatment failures. The other aims will also include (i) search for reliable prognostic parameters in the further prognosis of patients with PM/DM and (ii) studies on the pathogenic aspects of IIM. The investigations of serum, lymphocytes, muscle tissue and MRI will be organized. DNA and RNA will be stored for future genetic studies. Patients with definite or probable PM or DM diagnosed according to diagnostic criteria will be enrolled. They will have disease activity that according to physician's own judgement requires high dose immunosuppressive treatment (based on clinical assessment of weakness, elevation of muscle enzymes and, if available, on magnetic resonance imaging findings). Patients should be previously untreated with the exception of GC treatment up to 8 weeks. Patients with other than primary idiopathic PM or DM, such as drug-induced myositis, myositis in association with other connective tissue disease, inclusion body myositis, malignancy related myositis, and juvenile DM will be excluded. All patients will start with prednisone 1 mg/kg/day and the dose will be tapered if patients meet definition of improvement, which has been proposed by IMACS group. MTX will be administered orally, once weekly, with a starting dose 10 mg. This will be increased gradually to 25 mg/week if tolerated by week 5. Patients will be first assessed after 2 weeks and than monthly for a period of 48 weeks. There will be a follow-up after a further 1 year in order to find out the impact of the early treatment on the long-term disease outcome. All efficacy analyses will be performed using intention-to-treat population (ITT). In addition, the primary and secondary variables will be analysed using the per-protocol population, which will contain all patients in the ITT population, who also reached Week 48 without any major protocol violations. The safety population, which will contain any patient who received at least one dose of study drug, will be used for all safety analyses.

This study will assess the safety and efficacy of H.P. Acthar gel for treating the cutaneous manifestations in patients with refractory classic dermatomyositis, juvenile dermatomyositis, and amyopathic dermatomyositis. Our hypothesis is that H.P. Acthar gel will be both safe and effective for such patients.

This study will examine whether infliximab (Remicade ) is safe and effective for the treatment of dermatomyositis and polymyositis. Infliximab blocks the effect of a protein called tumor necrosis factor (TNF), which is associated with harmful inflammation in many diseases. Patients 18 years of age and older with active dermatomyositis or polymyositis that does not respond adequately to treatment with methotrexate and corticosteroids may be eligible for this study. Candidates will be screened with a medical history, physical examination, blood and urine tests, chest x-ray, pulmonary function test, skin test for tuberculosis, HIV test, electromyography (described below), manual muscle testing, and functional assessments. Magnetic resonance imaging (described below) will be done to assess the degree and location of inflammation in the involved limbs. An electrocardiogram and echocardiogram will be done if recent ones are not available. Patients who qualify for the study will be asked to undergo two muscle biopsies (surgical removal and analysis of small pieces of muscle tissue), one before initiation of treatment and another on the 16th week . Participants will be randomly assigned to receive either 3 mg/kg body weight of infliximab or a placebo (inactive substance) by infusion through a vein over 2 hours. The infusions will be given at the beginning of the treatment period (week 0) and at weeks 2, 6 and 14. At week 16, strength will be assessed by manual muscle testing. Patients who improved with treatment will continue with the same infusion dose on weeks 18, 22, 30, and 38. Those who do not improve will be assigned by random allocation to receive either 5 mg/kg body weight or 10/mg/kg body weight of infliximab on weeks 18, 22, 30 and 38. Those who did not improve who were previously on the placebo infusion will receive an extra dose of either 5 mg/kg or 10 mg/kg body weight of infliximab on week 16, while those patients who were previously on 3 mg/kg body weight of infliximab who failed to meet the improvement criteria will receive an infusion containing no medication on week 16. Patients will be admitted to the hospital for infusions at weeks 0, 14 and 38; the rest will be given on an outpatient basis. After the 38th week, all infusions will be stopped and patients will be assessed on the 40th week. Participants will undergo some or all of the following tests and evaluations during treatment: Blood tests every week to look for antibodies seen with muscle inflammation. Some of the blood samples will be stored for later testing, including genetic studies to find genetic differences related to inflammation. Skin test for tuberculosis Chest x-rays at the beginning of the study (if a recent one is not available) and again at weeks 16 and 40 to look for active infection, detect signs of past exposure or infection with diseases such as tuberculosis, and assess the presence of lung disease that might be related to the myositis. MRI (usually of the legs) at the beginning of the study and again at weeks 16 and 40 to measure disease activity and extent of muscle involvement. This will also give an idea of the response to treatment. This test uses a magnetic field and radio waves to produce images of body tissues. During the procedure the patient lies on a bed surrounded by a metal cylinder (the scanner). Muscle biopsy at the beginning of the study to diagnose muscle inflammation and again at week 16 to evaluate the response to treatment. Electromyography if the patient has not had an EMG previously. For this test, small needles are inserted into the muscle to assess the electrical activity of the muscle HIV test Patients whose disease worsen with treatment or who develop serious drug-related side effects will be taken off the study and referred back to their primary care physician for further therapy. Patients who improve will be referred back to their primary physician at the end of the study for possible continued treatment. Participants will be asked to return for follow-up visits every 6 weeks for a total of 30 weeks to monitor long-term effects of the drug

This study of inflammatory muscle diseases-polymyositis and dermatomyositis and related disorders-will examine what causes these diseases and describe the clinical features (signs and symptoms) associated with them. Inflammation and degeneration of skeletal muscles in these disorders leads to weakness and muscle wasting. The skin, lungs and other organs may also be involved. Patients 16 years of age and older with polymyositis, dermatomyositis, or a related disorder may be eligible for this study. Participants will undergo a complete history and physical examination, including routine blood and urine tests. Additional procedures for diagnosis, treatment or research may include: Blood sample for genetic studies. Muscle biopsy-removal of a tissue sample for microscopic examination. Under local anesthetic, a 1/2- to 1-inch long incision is made in the thigh or upper arm, and a small piece of muscle is removed. Electromyography-measurement of the electrical activity of a muscle. A needle is inserted through the skin into a muscle to record its electrical activity. Magnetic resonance imaging-visualization of organs or tissues, using a magnetic field and radio waves. The patient lies on a table inside a narrow cylinder (the MRI scanner) with a strong magnetic field for the scanning. Manual muscle strength testing by a physiotherapist. Swallowing studies using ultrasound (imaging using sound waves) and X-rays (barium swallow) to evaluate swallowing and speaking abilities. Questionnaires on swallowing ability and ability to perform daily living activities Pulmonary function tests-measurement of movement of air in and out of the lungs. The patient breathes into a machine to evaluate lung function. Chest X-rays to evaluate lung function. Electrocardiogram and, if necessary, Holter monitoring (measurement of the electrical activity of the heart) and echocardiogram (ultrasound imaging of the heart) to evaluate heart function. Apheresis-collection of white blood cells for research. Whole blood is collected through a needle placed in an arm vein. The blood circulates through a machine that separates it into its components. The white cells are removed and the rest of the blood is returned to the body through the same needle or through a second one placed in the other arm. MR guided muscle biopsy-measurement of glycogen in muscle tissue using magnetic resonance imaging. Certain patients may undergo this experimental procedure to compare MRI findings with those of muscle biopsy. The affected muscles are identified using MRI and the biopsy incision is made. MRI is then used to guide the biopsy needle to the muscle and a small piece is removed. Patients who are eligible for experimental treatment studies will be offered the opportunity to join them. Others will be advised of treatment recommendations.
