Active clinical trials for "Granulomatosis with Polyangiitis"

The aim of this trial is to lower the morbidity rate in elderly patients affected with systemic necrotizing vasculitides, by reducing mortality and improving global outcome.

This study will examine the use of rituximab in patients with Wegener's granulomatosis (WG) who have experienced a relapse of the disease through standard therapies. Rituximab is an antibody directed against the human protein called CD20, found on the surface of normal and abnormal B lymphocytes. Rituximab decreases the number of B lymphocytes. This study will examine the safety of rituximab in WG and rituximab's ability to reduce the level of circulating antineutrophil cytoplasmic antibodies (ANCA), which are antibodies that react to substances found in white blood cells. ANCA have been found to be strongly associated with WG. The study will also explore whether rituximab can reduce the occurrence of disease relapse. WG is a disease marked by inflammation of blood vessels. It can involve many different parts of the body, including the sinuses, lungs, kidneys, brain, nerves, eyes, intestinal tract, skin, joint, heart, and others. Before the use of cytotoxic drug therapy, WG was almost always fatal if untreated, with a mortality rate of 93% within 2 years. Patients 18 to 75 years of age who have a history of at least one relapse of the disease despite standard treatments, who have had active WG within the previous 12 months and are in remission, who are receiving either methotrexate or azathioprine for remission maintenance, and who have circulating ANCA, may be eligible for this study. A minimum of 22 visits to the clinic will be required to complete the entire study. Patients will undergo a comprehensive medical evaluation, with laboratory studies and x-rays. There may also be consultations and possible biopsies of affected organs only if medically indicated for diagnosis and treatment of the disease. In the 4-week period that patients will receive rituximab infusions, the methotrexate or azathioprine will be continued at the same dosage unless there are side effects that requite the medication to be temporarily stopped or the dosage reduced. Patients will receive four doses of rituximab, at 375 mg per meter squared of body surface area, once a week. It will be infused into a vein, through an intravenous catheter. For the first dose, patients will be admitted as inpatients for at least 24 hours, for monitoring during the infusion and for any reactions associated with it. The second, third, and fourth rituximab infusions may be given either on an inpatient or outpatient basis to be decided on how the patient tolerates the first infusion. Following the four infusions, there will be blood tests to monitor the safety of the medication and the status of the disease, to be done at home every week for 4 weeks. Results will be sent to the researchers by fax. Patients will be asked to return to the clinic 1 month after the fourth infusion and every 1 to 3 months afterward. If there are no side effects or a relapse of the disease, the methotrexate or azathioprine will be continued for 2 years past remission. If by then the disease then remains in remission, the dose of either medication will be gradually decreased and eventually stopped. The usual schedule is to reduce methotrexate by 2.5 mg per month and to reduce azathioprine by 25 mg per month. If at that point there are no signs of active disease, the patients' illness will be considered to be in continued remission and no further treatment will be necessary. If relapse does occur, treatment would be different than previously. In most cases, treatment would involve prednisone and cyclophosphamide or methotrexate If the ANCA finding is negative after rituximab treatment and again becomes positive, and there is evidence of a return of B lymphocytes, patients may receive a second course of four rituximab infusions.

This study will compare the safety and effectiveness of two drugs-methotrexate and mycophenolate mofetil (MPM)-in preventing disease recurrence in patients with Wegener's granulomatosis and related inflammatory blood vessel disorders. The standard treatment for these conditions is combination drug therapy with prednisone plus cyclophosphamide. However, although most patients improve on this therapy and achieve disease remission, many experience a relapse (return of the disease) some time after therapy is stopped. Also, these drugs can produce serious side effects during treatment. This study will test a new treatment regimen to try to maintain disease remission in these patients with minimal side effects. Patients with Wegener's granulomatosis or other related blood vessel disorders between 10 and 80 years old will be considered for this study. All participants will start therapy with daily doses of prednisone and cyclophosphamide. Prednisone will be reduced gradually and then stopped after symptoms improve significantly. Cyclophosphamide will continue until the disease is in remission. Patients in remission will then be randomly assigned to continue treatment with either MPM or methotrexate. MPM is taken twice a day by mouth. Methotrexate is taken once a week, usually by mouth, but in some cases, by injection into a muscle or under the skin. Patients who do well and have no side effects will continue treatment for 2 years. Then, the drug will gradually be reduced (usually at monthly intervals) and finally stopped. No further treatment will be given unless a relapse occurs. At that time, the type of treatment will depend on various medical factors, including the severity of the recurrence and the patient's history of drug side effects. Physical examinations and various tests, including blood and urine analyses, and X-rays, will be done periodically to evaluate the response to treatment and monitor drug side effects. The total duration of the study-from the screening evaluation through a 2-year follow up after all medications have been stopped-is about 5 to 6 years.

This study will examine the use of etanercept (also called Enbrel or TNFR:Fc) in patients with Wegener's granulomatosis, a type of vasculitis (blood vessel inflammation). Wegener's granulomatosis may affect many parts of the body, including the brain, nerves, eyes, sinuses, lungs, kidneys, intestinal tract, skin, joints, heart, and other sites. Generally, the greater the disease involvement, the more life-threatening it is. Standard treatment is a combination of prednisone and a cytotoxic agent-usually cyclophosphamide or methotrexate. However, many patients treated with this regimen have a disease relapse, and others cannot take these drugs because of severe side effects. This study will evaluate etanercept's safety and effectiveness, and particularly its value in reducing the need for prednisone and preventing disease relapse. The Food and Drug Administration has approved etanercept for treating rheumatoid arthritis, another inflammatory disease. The drug works by blocking the activity of TNF-a protein made by white blood cells that is involved in the inflammatory process. Since prednisone also affects inflammatory proteins and lowers TNF production, the use of etanercept may reduce the need for prednisone in patients with Wegener's granulomatosis, and thus the risk of its side effects. Patients between 10 and 70 years of age with Wegener's granulomatosis who have never taken prednisone, methotrexate or cyclophosphamide, or have taken these drugs for less than 3 weeks may be eligible for this study. Participants will have a medical history review and physical examination, including laboratory studies. If medically indicated, X-rays, consultations and biopsies (surgical removal of a small tissue sample) of affected organs will also be done. All patients will begin treatment with prednisone, methotrexate and etanercept. Those who improve on this regimen will stop prednisone gradually over 3 months. Those who achieve disease remission at the end of another 3 months will be randomly assigned to either continue taking etanercept and methotrexate for another 12 months or to stop etanercept and continue only methotrexate for the next 12 months (after which methotrexate will gradually be stopped). Patients who are not in remission by the 6-month point will continue taking etanercept until they go into remission, when they will be assigned to stop or not stop etanercept, as described above. Patients who do not achieve remission within 12 months of beginning treatment will be taken off the study. Patients who have a disease relapse while on the study will likely be switched to treatment with prednisone and either methotrexate or cyclophosphamide. Patients randomized to stop etanercept and who have a relapse within a year of stopping the drug may be offered re-treatment on this protocol, but with continuing etanercept for a full year after remission. Patients will be evaluated in the outpatient clinic every 2 to 4 weeks for the first 4 months and every 1 to 3 months after that. Patients whose disease is in remission and who stop all medications will be followed every 3 to 6 months for 2 years. Follow-up evaluations include a physical examination, blood draws and, if medically indicated, X-rays. The total study duration is 60 to 70 months.

The purpose of this study is to assess the safety, tolerance, and immunologic effects of interleukin-10 (IL-10), in patients with Wegener's granulomatosis. A secondary objective is to determine if IL-10 demonstrates sufficient anti-inflammatory activity in the treatment of Wegener's granulomatosis to warrant further study in a larger trial. In this study, IL-10 will be given either alone or in combination with standard therapeutic agents, usually consisting of cyclophosphamide, methotrexate, and/or prednisone. Patients will be eligible to receive IL-10 when there is evidence of active disease. IL-10 will be administered by subcutaneous injection at a dose of 4 µ (Micro)g/kg/day for 28 days.

This is a perspective, Phase IV, multi-center, single arm, open-label, interventional study in adult participants with Wegener's granulomatosis (granulomatosis with polyangiitis [GPA]) or microscopic polyangiitis. Participants will be treated with rituximab (Ristova) and glucocorticoids. Rituximab will be administered by intravenous (IV) infusion at a dose of 375 milligrams per meter square (mg/m^2) body surface area once weekly during Weeks 1 to 4. Participants will also receive one or three pulses of methylprednisolone (1000 milligram [mg] each), followed by a tapering dose of oral prednisolone (start dose of 1 mg per kilogram per day). The dose of oral prednisone will be reduced as per evaluation by the investigator till the participant is completely off the drug. The participants will be followed up for duration of 6 months from the date of starting rituximab therapy with three follow-up visits at Days 52, 112 and 172. All adverse events occurring during this period will be captured.

The aim of this study is to assess the efficacy of a rituximab regimen based on rate of ANCA and CD19 lymphocytes for maintenance treatment in systemic ANCA-associated vasculitis: prospective, multicenter, controlled, randomized comparative study of two rituximab regimens: one based on ANCA and CD19 lymphocytes versus systematic infusions.

The purpose of this study is to determine whether plasma exchange as well as immunosuppressive therapy are effective in reducing death and end-stage renal disease (ESRD). The trial will also study whether a reduced cumulative dosing regimen of glucocorticoids is as effective as a standard disease regimen. The FDA-OOPD is one of the funding sources for this study.

Wegener's granulomatosis (WG) is a rare disease that causes inflammation of blood vessels, or vasculitis. It may involve many different parts of the body, but typically affects the upper and lower respiratory tract and kidneys. The purpose of this study is to determine the safety and effectiveness of the medication abatacept in treating adults with mild relapsing WG.

This study will evaluate a new technique for examining the air passages of the lungs called "virtual bronchoscopy." It involves using computed tomography (CT) images of the chest to generate a 3-dimensional model of the walls of the trachea and bronchi (airway passages). This non-invasive method lets doctors see small masses and areas of narrowing in the passages without having to do surgery or pass a tube through them. Patients with diseases of the air passages who are enrolled in an NIH clinical trial may participate in this study, which requires having a CT scan. The patient lies on a table that slowly slides into a hole in a donut-shaped X-ray machine (the scanner). Patients may have to hold their breath several times during the procedure. Some patients may be given an injection of a contrast agent through a catheter (thin tube) placed in an arm vein to improve visibility of abnormalities. Patients may also be asked to breathe oxygen through nasal prongs to allow them to hold their breath longer. The procedure usually takes 15 to 20 minutes.
