Active clinical trials for "Arthritis"

This study will evaluate the efficacy and safety of ocrelizumab, compared with placebo, in combination with methotrexate in patients with active rheumatoid arthritis who have had an inadequate response to methotrexate. Patients will be randomized to receive placebo, 200mg of intravenous ocrelizumab or 500mg of i.v. ocrelizumab on Days 1 and 15. A repeat course of i.v. treatment will be administered at Weeks 24 and 26. All patients will receive 7.5mg - 25mg/week concomitant methotrexate at a stable dose. The anticipated time on study treatment is 1-2 years. Target sample size is 1000.

This single arm study will investigate the pattern of B cell depletion in synovial tissue and peripheral blood of patients with active RA, after MabThera (1000mg iv x 2 on days 1 and 15) + methotrexate (10-25mg/week po) treatment. The clinical efficacy and pharmacokinetic profile of MabThera after treatment and retreatment will also be investigated. The anticipated time on study treatment is 2+ years, and the target sample size is <100 individuals.

This Phase 2b study is designed to evaluate the efficacy and safety of BG9924 given subcutaneously (SC) versus placebo in participants with active rheumatoid arthritis (RA) who have previously had an inadequate response to treatment with anti-tumor necrosis factor (anti-TNF) therapy.

Rheumatoid arthritis disease is believed to be due to immune cells, cells that normally protect the body and are now causing damage to the body. Risk of death is highest in people with twenty or more joints actively involved with disease, positive rheumatoid factor, an elevated sedimentation rate (laboratory measures of active inflammation), and patients with limitation of daily activities (trouble doing simple things like opening a carton of milk). In these high risk patients, life is significantly shortened. Death is usually from heart disease, kidney failure, neck dislocation, broken hip bones, or blood clots to the lung. In this study we use moderate dose chemotherapy (cyclophosphamide and fludarabine) and CAMPATH-1H (a protein that kills the immune cells that are thought to be causing the disease), followed by infusion of blood stem cells that have been collected from the patient's brother or sister (allogeneic stem cell transplant). The purpose of the moderate dose chemotherapy and CAMPATH-1H is to destroy the cells in the immune system and to allow the cells from the patient's brother or sister to grow. The purpose of the stem cell infusion is to restore blood cell production, which will be severely impaired by the moderate dose chemotherapy and CAMPATH-1H, and to produce a normal immune system that will no longer attack the body.

The purpose of the study is to evaluate the clinical efficacy of scheduled versus free reduction of steroid treatment in patients with active RA treated with adalimumab + MTX

This study will determine whether a stepwise increase of the drug infliximab (Remicade® (Registered Trademark)) controls juvenile rheumatoid arthritis more effectively than a fixed dose. It will look at the safety and effectiveness of increasing the dose to a maximum of 15mg/kg body weight per dose, examining the drug's effect on bone and cartilage, and whether it can improve abnormal growth, metabolism and hormones. Infliximab is approved for treating adults with rheumatoid arthritis and Crohn's disease. Children between 4 and 17 years of age with active juvenile rheumatoid arthritis who do not respond adequately to standard therapy may be eligible for this study. Participants will receive nine infusions of infliximab during this 62-week study. The drug is given intravenously (IV, into a vein) over 2 hours. The first three infusions will be at a dose of 5 mg/kg of body weight. Children who improve on this regimen will receive another 6 infusions at the same dose. Children who do not significantly improve on 5 mg/kg at the end of 6 weeks (the third infusion) may continue with phase 2 of the study, in which they will be randomly assigned to receive either: 1) 6 additional doses of the drug at 5 mg/kg per dose, or 2) a gradually increased dose to a maximum of 15 mg/kg. In addition, all children will continue to take methotrexate at the same dose as when they entered the study. Participants will visit the NIH Clinical Center 12 times (about every 8 weeks) during the study for the following tests and procedures: History and physical examination, including a complete joint exam Puberty assessment - breast development in girls, testicle size in boys, and pubic hair Height and weight measurements Children will have imaging studies (x-rays, MRI and Dexa scan) at the beginning and end of the study and will collect a 24-hour urine sample before each infliximab infusion. Patients may elect to have an endocrine evaluation. This involves Clinical Center hospitalizations for 1-1/2 days on visits 1, 4 and 12. Small amounts of blood will be drawn every 20 minutes (through an indwelling catheter to avoid multiple needle sticks) for 8 hours while the child sleeps. The blood will be examined for the normal rhythm of growth hormone and other substances in the body and how they are affected by arthritis. Participants will complete a questionnaire once a year for 2 years to provide information on their health status and any problems that might be related to the study drug.

The primary objective of this study was to determine the efficacy of etanercept in pediatric patients with systemically active system onset juvenile rheumatoid arthritis (SOJRA).

The primary objective of this study is to compare the therapeutic response and safety of 3 oral dose levels of CCI-779, with placebo in subjects with active rheumatoid arthritis (RA) who have been receiving stable doses of methotrexate (MTX) for at least 8 weeks.

The purpose of this study is to determine the safety, tolerability and efficacy of natalizumab in subjects diagnosed with moderate to severe rheumatoid arthritis (RA) receiving concomitant treatment with methotrexate (MTX). It is thought that natalizumab may stop the movement of certain white blood cells, known as lymphocytes, into joint tissue. These cells are thought to cause damage in the joints leading to the symptoms of RA.

The primary objective of this study is to evaluate the effect of filgotinib compared to placebo as assessed by the American College of Rheumatology 20% improvement (ACR20) response in participants with active psoriatic arthritis who are naive to biologic disease-modifying anti-rheumatic drug (DMARD) therapy. The study consists of two parts, the Main Study and the Long Term Extension (LTE).
