Purpose:

The purpose of the study is to assess the safety, tolerability, and efficacy of etanercept in patients with dermatomyositis.


Study summary:

Dermatomyositis (DM) is one of the major subtypes of idiopathic inflammatory myopathy. Prednisone is the initial treatment of choice in most patients with DM. However, because of the high rate of patients with disabling weakness despite treatment with prednisone, the long-term side effects of prednisone, and the many side effects associated with other second-line immunosuppressive agents (e.g., methotrexate, azathioprine), better treatment options are needed. There is evidence that tumor necrosis factor-a (TNF-a) plays a role in the pathogenesis of DM. Thus, etanercept, which blocks TNF-a, is a logical drug to assess in DM. Etanercept has been associated with a number of side effects including an increased risk of infection, inducing other autoimmune diseases, and perhaps cancer. These risks may be further enhanced in DM in which the frequency of other autoimmune disorders (e.g., connective tissue disease) and malignancy are already increased. The goal of this pilot study will be to assess the safety and tolerability of etanercept in DM.We will perform a double-blind, placebo-controlled pilot study of etanercept in 40 patients with DM randomized in a 3:1 ratio to receive etanercept or placebo. All newly diagnosed and untreated patients will be started on a standard dose of prednisone and tapering schedule. Refractory patients who have been or are currently being treated with prednisone, IVIG, or methotrexate can also participate. Subjects will be followed for 1 year and we will assess various outcome variables recommended by the The International Myositis Assessment Clinical Study Group (IMACS). The primary aim of the study is to preliminarily assess the safety and tolerability of etanercept in patients with DM. We hypothesize that etanercept will be safe and well tolerated in this population. The second aim is to assess the safety and tolerability of prednisone in the dosing schedule we propose to use. We hypothesize that most patients will be able to tolerate the reduction of the prednisone dosage but most will not be able to be completely weaned off the medication. We believe we will find a relationship between prednisone dosage and its related side effects. The third aim of the study is to assess the variability, reliability, and responsiveness of the outcome measures recommended by IMACS using this pilot study of etanercept as the vehicle. The information gained from this study is necessary in order to design larger therapeutic trials of etanercept and other drugs in dermatomyositis.


Criteria:

Inclusion Criteria: Study subjects must meet the following criteria: 1. Meet the diagnostic criteria for DM (a-c; a,b,d; or a,c,d) 1. Subjects must have symmetric proximal greater than distal weakness 2. Characteristic DM rash consisting of any or all of the following: heliotrope, shawl sign, V-sign, Gottron's sign, Gottron's papules, periungual telangiectasias 3. Laboratory evidence of myopathy with at least one of the following: an elevated serum CK or aldolase level, myositis-specific antibody, electromyography (EMG) demonstrating myopathic features (e.g., muscle membrane instability, myopathic units, or early recruitment), or an abnormal skeletal muscle MRI showing diffuse or patchy edema within the muscles. 4. A muscle biopsy will be optional if the patient fulfills criteria a-c. The subject must demonstrate symmetric proximal weakness (criteria a) for entry into the study. If the subject does not have a definite rash (criteria b) or laboratory evidence of a myopathy (criteria c), a muscle biopsy will be required. The muscle biopsy must demonstrate one of the following: perifascicular atrophy, expression of MHC 1 on perifascicular muscle fibers, MAC deposition on small blood vessels, tubuloreticular inclusions in endothelial cells on EM, or MXA expression on muscle fibers of blood vessels 2. Newly diagnosed subjects should be able to walk independently 30 feet (cane, walkers, orthoses allowed). However, subjects with refractory dermatomyositis may be non-ambulatory. 3. Age > 18 years 4. Patients must not use topical skin ointments for treatment of the dermatological manifestations as it will interfere with skin assessment. 5. Men and women of childbearing age must be willing to use a method of birth control. 6. Able to give informed consent 7. Subject or designee must have the ability to self-inject investigational product or have a care giver at home who can administer subcutaneous injections Exclusion Criteria The presence of any of the following excludes subject participation in the study: 1. Presence of any one of the following medical conditions: active infection, uncontrolled diabetes mellitus, MI, CVA or TIA within 3 months of screening visit, symptomatic cardiomyopathy (congestive heart failure), symptomatic coronary artery disease, uncontrolled hypertension (sitting systolic BP <80 mm Hg or > 160 or diastolic BP > 100 mm Hg), oxygen-dependent severe pulmonary disease, systemic lupus erythematosus (SLE), cancer (other than basal cell skin cancer) less than 5 years previously, HIV or other immunosuppressing disease, positive PPD test or any history of mycobacterial disease, chronic hepatitis B or hepatitis C, history of multiple sclerosis, transverse myelitis, optic neuritis, chronic inflammatory demyelinating neuropathy, epilepsy, or other chronic serious medical illnesses 2. Presence of any of the following on routine blood screening: WBC<3000, Platelets < 100,000, hematocrit < 30%, BUN > 30 mg %, symptomatic liver disease with serum albumin < 3 G/DL, PT or PTT > upper range of control values 3. Forced Vital Capacity < 50% of predicted 4. History of non-compliance with other therapies 5. Any prior or concurrent cyclophosphamide, or current use of any immunosuppressive agent besides methotrexate (e.g., azathioprine, mycophenolate, or cyclosporine) 6. Coexistence of other neuromuscular disease that may complicate interpretation of the results of the study 7. Drug or alcohol abuse within last 3 months 8. Pregnancy or breast feeding 9. Juvenile DM 10. Subjects who have known hypersensitivity to Enbrel or any of its components or who is known to have antibodies to etanercept 11. Use of a live vaccine 90 days prior to, or during this study. 12. Subject is currently enrolled in another investigational device or drug trial(s), or subject has received other investigational agent(s) within 28 days of baseline visit. 13. Concurrent sulfasalazine therapy
