Active clinical trials for "Arthritis"

This is a continuation trial of LymphoStat-B™ to evaluate the long-term safety in subjects with Rheumatoid Arthritis that completed study LBRA01 and benefitted from treatment.

To assess comparative radiographic efficacy, clinical efficacy and safety of etanercept (ETN) + methotrexate (MTX) with usual disease-modifying anti-rheumatic drug (DMARD) treatment in subjects with moderate RA who were treated with MTX monotherapy, but continue to have moderate disease activity.

The purpose of this new research study is to gain additional information about how safe and effective R935788 is over a longer period of time.

This is a Phase I multicenter study that will be conducted in the United States and consists of a double-blind, placebo-controlled, SAD stage, followed by a double-blind, placebo controlled MAD stage. The study will be conducted in approximately 65 adult patients between 18 and 80 years old who have RA.

To compare the efficacy of SMP-114 (120 and 240 mg/d) versus placebo in terms of the percentage of patients meeting the American College of Rheumatology criteria for 20% improvement in RA (ACR20) at week 24. The study hypothesis would be to demonstrate that the use of methotrexate and SMP-114 is more efficacious than Methotrexate alone.

The assessment of otelixizumab in rheumatoid arthritis subjects will provide safety, tolerability, pharmacodynamic and pharmacokinetic information which will enable the identification of appropriate safe and well-tolerated dosage regimens to be used in clinical efficacy studies. This study will consist of a screening phase, followed by a treatment period where four cohorts of subjects will receive 5 daily intravenous infusions of otelixizumab. The cumulative dose will increase in each successive cohort and infusion rates can be adjusted based on signs and symptoms of cytokine release syndrome and to ensure the specified maximum infusion rate is not exceeded. Serial blood samples will be obtained for clinical laboratory testing, determination of pharmacodynamic markers, serum otelixizumab PK parameters, exploratory biomarkers and immunogenicity. Safety and pharmacodynamic data from the previous cohort(s) will be evaluated prior to dosing subsequent cohorts to ensure safety. Adverse events, laboratory values, vital signs and ECG's will be monitored closely during this study. All subjects in the study will undergo long-term follow-up out to 48 months to monitor patient safety.

The purpose of this study is to monitor the performance and determine the metal ion release of the Pinnacle™ Cup with a metal-on-metal bearing combination in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments. A subset of patients will also have blood samples taken at regular intervals to allow the metal ion levels to be determined.

The purpose of this research study is to determine fatigue (tiredness) in subjects with chronic Rheumatoid Arthritis with chronic anemia. Fatigue in subjects who get PROCRIT will be compared to fatigue in subjects who get placebo (a medically inactive substance). The study will also evaluate hemoglobin levels (oxygen-carrying protein in red blood cells), safety, anemia related health concerns, vitality, arthritis related function and work productivity.

The main purpose of this study is to assess whether adding a multifaceted lifestyle intervention to the standard best practice of care can be more effective than standard best practices alone for treating Rheumatoid Arthritis.

Rheumatoid Arthritis (RA) is a chronic autoimmune disease that affects nearly 1% of the general population worldwide leading to joint inflammation, disability and increate mortality. Several factors are associated with disease activity and treatment outcomes. Among them, overweight/obesity status was demonstrated to be associated with higher risk of RA development and most importantly to different treatment response to biological DMARDs. Moreover, overweight/obese RA patients do show higher degree of synovial inflammation compared to lean RA patients. In this context, adipose tissue accumulation is associated with higher inflammatory burden through the secretion by activated mature adipocytes of adipokines with pro-inflammatory properties on innate and adaptive immune cells. Among them, Leptin is an important adipokine, released by mature adipocytes with multiple activating properties on immune cells as monocytes, macrophages, dendritic cells, T and B lymphocytes acting through the activation of its receptor LEPR via JAK/STAT pathway. In particular, leptin exerts its effects on macrophages populations through the promotion of M1 differentiation with pro-inflammatory phenotype. In our research hypothesis we expect that leptin levels does correlate with immunohistochemical scores of synovial inflammatory cells (CD68+, CD21+, CD20+ and CD3+) and CD31+ synovial vessels. Moreover, we expect that the inhibition of JAK/STAT signal using Tofacitinib may interfere with leptin activation action on resident synovial inflammatory cells expressing LEPR (as CD68+, CD20+ and CD3+) in particular restoring the M1/M2 phenotype ratio within resident macrophages populations. Finally, we expect that the inhibition of JAK/STAT signaling pathway by Tofacitinib will result in a significant reduction of synovitis degree in patients with higher leptin expression due to adipose tissue activation.
