To continue to assess the clinical safety and efficacy of Certolizumab Pegol as add-on therapy with stable-dose Disease Modifying Anti-Rheumatic Drugs (DMARDs)
Infliximab is a chimeric monoclonal antibody directed towards Tumor Necrosis Factor -alpha that is largely used in inflammatory diseases such as rheumatoid arthritis (RA). A relationship between dose and clinical outcomes was shown in populations of RA patients but there is an interindividual variability of this relationship. At an individual level, this dose-effet relationship can be separated into the dose-concentration (pharmacokinetic or PK) and the concentration-effet (pharmacokinetic-pharmacodynamic or PK-PD) relationships. Serum trough concentrations of infliximab have been shown to be variable between patients receiving the same treatment regimen. This PK variability may be explained by several factors (e.g. genetic and immunological factors). The concentration-effect relationship may also be variable and the sources of this variability need to be studied as well. To date no detailed infliximab PK analysis has been published. The sources of variability of the dose-effect relationship need to be characterized to optimize infliximab dosing regimen in patients. The FAKIR study is a multicenter prospective observational study that will focus on patients treated with infliximab. Its aims are: 1. to characterize the PK and PK-PD variability of infliximab in RA, using clinical criteria and biomarkers, assessed over time ; 2. to study the influence of the polymorphism of FCGRT (the gene encoding FcRn) on the PK variability of infliximab; to study the influence of the polymorphism of FCGR3A (the gene encoding Fc gamma RIIIa) on the PK-PD variability of infliximab; and to study the influence of antibodies toward infliximab on the PK and PK-PD variabilities of infliximab.
This study will evaluate the safety and tolerability of PF-04236921 administered monthly as three intravenous infusions. Each group of patients will be assigned to a dose level; Safety and tolerability of a low dose level will be required before proceeding to successively higher dose levels. Blood tests will be performed to measure the amount of drug and changes in measures of inflammation.
The study will try, in 2 separate parts, each using 12 research subjects, to see how a new form of the pill CE 224,535 gets released into the bloodstream and whether that is affected by food. In each part, subjects will switch among 4 treatment periods to take either different forms of the pill(s) or the same form either after fasting or eating a meal. The second part will only happen depending on whether the sponsor believes it is needed and will use separate subject than the first part.
To evaluate the safety and tolerability of LY2127399 administered as subcutaneous injections for 48 weeks in participants with Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a chronic disease that leads to inflammation and progressive joint damage. RA is a systemic inflammatory autoimmune disorder affecting almost 1% of the United States population. Current therapies target the immune system early in the disease process before joint damage occurs, and include drugs such as methotrexate (MTX) and tumor necrosis factor (TNF)-blocking agents. The primary purpose of this study is to determine the effectiveness of two TNF inhibitors, etanercept and adalimumab, on memory B lymphocytes (B-cells) in the peripheral blood of participants with RA. Additionally, there are 4 optional sub-studies as part of the trial: - B-Cell Kinetic Sub-Study to look at changes in B-cell subsets over time and how quickly reductions in B-cell memory occur - Vaccine Response Sub-Study to assess B cell memory in response to immunization with hepatitis B,-hepatitis A, and diphtheria/tetanus vaccines, and to determine whether T-cell vaccine responses are altered with TNF blockade - Tonsil Biopsy Sub-Study to evaluate how TNF blockade affects memory B-cells in the tonsil dendritic cells and germinal cells - Synovial Biopsy Sub-Study to evaluate how TNF blockade affects changes in memory B-cells in lymphoid tissue.
Investigate body image of patients with rheumatoid arthritis, correlating with self-esteem, function and quality of life.
The objective of this study is to evaluate the activity of 2 oral doses of AB1010 in subjects suffering from active RA who have shown an inadequate response to one DMARD including MTX or anti-TNF, after 3 months (12 weeks) of treatment. The safety and efficacy will be evaluated on: Rate of patients achieving ACR 20, 50, 70 and 90 DAS (disease activity score) after 3 months treatment ACRn after 3 months treatment Therapeutic maintenance of AB1010 at 3 months Quality of Life assessed by SF12 Health Assessment Questionnaire (HAQ) Clinical and biological safety Pharmacokinetic profile of AB1010
Previous studies have analyzed serological responses following pneumococcal vaccination using 23-valent vaccination (Pneumovax) in Rheumatoid Arthritis (RA) patients that were on different therapeutic modalities including TNF-blockers and methotrexate. The results have shown that serological response was significantly reduced in RA patients receiving methotrexate compared to those receiving TNF-blockers. In contrast when using polypeptide immunisation (influenza vaccine) we found that anti-TNF significantly impaired the serological response compared to the methotrexate treated RA patients. The aim of this study is to analyze serological responses after Prevenar vaccination in patients with chronic arthritis and to study the impact of different treatment modalities on serological responses. It will be of interest to see if the result is different compared to the one seen after immunizing with 23-valent nonconjugated pneumococcal polysaccharide vaccine.
