研究概览
简要总结
Sarcoidosis is a inflammatory disease affecting many parts of the body, especially the lungs. While most patients do well, there is a group of patients who require continuous doses of prednisone or other drugs. The current study will determine the role of Rituximab as new agent for patients with refractory disease.
详细描述
Patients with refractory pulmonary sarcoidosis will be eligible for participation in this open label trial of Rituximab as additional therapy. The study will evaluate the efficacy of rituximab in improving the symptoms and functional capacity in patients with chronic sarcoidosis with pulmonary involvement who are symptomatic despite current treatment.
