trial of adalimumab in progressive sarcoidosis

Conditions: Sarcoidosis

Summary: sarcoidosis is a rare disease that can affect any organ in the body. it is characterized by the buildup of immune-system (fights off infection in the body) cells in organs. these cells form small groups called granulomas, which lead to inflammation of the surrounding tissue. sarcoidosis most commonly affects the lung and the lymph nodes (part of the immune system). the signs usually include shortness of breath, fever, dry cough, and chest pain. other signs in many patients can include redness and painful lumps on the skin, reduced eyesight, joint pain, and rarely, nervous system damage. sarcoidosis commonly affects young and middle-aged adults. there are no approved therapies for the treatment of sarcoidosis. corticosteroid (steroid hormone) therapy is considered the standard treatment. only limited benefit has been shown when using corticosteroid therapy to ease lung symptoms or improve lung function in patients with sarcoidosis. also, the effects of other therapies (for example: methotrexate, cyclophosphamide, anti-malarial drugs, thalidomide) and other immunosuppressants (drugs that suppress a body's natural defense system \[immune system\]) which have been used in a small number of patients are not well known and can cause long term problems. the drug used in this study is called adalimumab. adalimumab is fda (food and drug administration) approved for patients with moderately to severely active rheumatoid arthritis. however, adalimumab is not approved for the treatment of sarcoidosis. adalimumab is experimental in this study. the purpose of this study is to evaluate the safety and effectiveness of adalimumab in the treatment of patients with sarcoidosis with pulmonary (lung) involvement who show symptoms of the disease even though they are currently being treated with medication.

this study consists of 11 visits (including screening). screening procedures: a chest radiograph (pa and lateral) must be obtained within 3 months prior to the first study injection. it must indicate that subject is free of tuberculosis (tb). the chest radiograph will also be used to confirm the stage of the disease. histologically proven sarcoidosis will be confirmed. demographic data, a complete medical history (including signs and symptoms of sarcoidosis), a physical examination (including vital signs, weight and height). the medical history will include questions about history of recent tb and history of close contact with persons who might have tb. concomitant medications, including the use of oral corticosteroids and immunosuppressants, will be reviewed and recorded. in addition the inclusion and exclusion criteria will be reviewed. a tuberculin skin test will be performed. a serum pregnancy test will be performed for all women within the 4-week period prior to the baseline (week 0) visit. all women must test negative for pregnancy at screening. ats dyspnea score will be assessed. the 6-minute walk test will be performed with borg's cr10 dyspnea score obtained before and after. pulmonary function tests \[pfts\] (spirometry) will be performed. blood samples for routine laboratory analyses will be obtained. ae monitoring will also be performed. subjects who qualify for the study should be assigned to receive treatment within 14 days of the screening visit except if additional time is required for repeat tb skin testing. patients should still meet all of the inclusion criteria and none of the exclusion criteria at the time of the baseline visit before starting the injections. subjects must agree to use appropriate contraception. the procedures involved at all study visits are described below. * informed consent: (screening visit): subjects will be asked to review this consent form and discuss with the study doctor or study staff any questions they may have * health and medication questions: (screen, weeks 0, 2, 6, 12, 24, 30, 36, 45, 52): subjects will be asked to answer questions about their health, their medical history, and the medications they take. * physical exam: (screen, weeks 6, 24, 52): do a physical exam. * vital signs: (screen, weeks 0, 6, 12, 24, 52): blood pressure, pulse, temperature * height and weight: (screen, week 52) * blood tests: (screen, weeks 12, 24, 45, 52): approximately 3 teaspoons of blood will be drawn from a vein in subject's hand or arm for these tests. * lung function test: (screen, weeks 24, 52): subject will be given a mouthpiece and asked to take deep breaths into a machine connected to a computer according to the cues of a staff member. the machine will measure the capacity of subject's lungs. * chest x-ray: (screen, weeks 12, 24, 52): * tuberculosis test: (screen only): subject will be asked specific questions regarding their history of tuberculosis (also called tb: a type of bacterial lung infection) or personal contact with people with active tuberculosis. subjects with active tuberculosis cannot be in the study. subjects will be given a skin test for tuberculosis. for all subjects in this trial, a tb skin test with negative results must be obtained. * 6 minute walk test: (screen, weeks 0, 12, 24, 52): subject will be asked to complete a test where they will walk for 6 minutes. subject will be asked specific questions regarding any shortness of breath they have. * pregnancy test: (screen only): a pregnancy blood test will be performed on all women of childbearing potential at the screening visit. the results of the test must be negative in order for subject to participate in the study. * ecg: (week 0 only) * study drug administration: (weeks 0, 2, 6, 12, 18, 24, 30, 36, 45): subject will receive study drug at the week 0 visit and be taught how to give themselves injections. subject will be given a supply of study drug and clinical supplies that will last until the next study visit. subject will be required to return all unused study drug as well as the packaging for the used study drug at each visit. * questionnaires: (weeks 0, 2, 12, 18, 24, 30, 36, 45): prior to receiving any study drug, subject will be asked questions about their symptoms and quality of life, including their ability to care for themselves and carry out normal everyday activities (respiratory and health surveys) and health questionnaires. all subjects will return for efficacy and safety evaluations at each time point including week 52, whether or not they complete the entire treatment schedule and whether or not they are (still) responding to treatment. we will watch carefully for signs and symptoms of chf and active tb at follow-up evaluations for all patients. the study agent will be stopped in subjects who are found to have nyha class iii or iv chf, severe right-sided heart failure, cor pulmonale, and/or active tb after enrollment in the study but they must return for further follow-up evaluations.
