Filter by:There is a correlation between the CD55, CD59, CD35 and CD46 expression on B lymphocytes of patients before and after treatment with rituximab and the level of depletion and repopulation time for these cells. The theoretical rationale of the study assumes that the correlation, if any, will be a negative correlation. However, the hypothesis of positive correlation (two-tailed test) will also be tested.
Observational registry to assess the longer-term risk of serious infections and malignancies reported with TNFα-blocker therapy, as well as the longer-term risk of cardiovascular and thromboembolic events in adult Rheumatoid Arthritis (RA) patients treated with Cimzia® as compared to non-biologic DMARD-treated controls.
The study will describe the short-term effects the study drug, rivaroxaban, has on the body when a patient is switched from enoxaparin injection (by needle) to oral rivaroxaban (by mouth) for the prevention of blood clotting in the veins after elective total hip or total knee replacement surgery. After providing written informed consent, screening procedures will be completed to assess eligibility. After enrollment, all patients will be switched from enoxaparin to rivaroxaban. Blood samples for the short-term effects of rivaroxaban will be taken at various times while in the subacute unit. At the time of discharge, if the study doctor feels it is appropriate, an adequate supply of rivaroxaban will be provided to complete the full course of therapy. Upon completion of rivaroxaban therapy, all patients will be required to have final study procedures performed. Safety evaluations at the final visit will include clinical blood laboratory tests, a physical examination, urine pregnancy test (if applicable), recording of any adverse events including details regarding any bleeding episodes or blood clot events, and assessment of the surgical wound. All patients will return any unused study medication and study participation will be complete.
The primary purpose of this study is to assess incidence rates of targeted infections, malignancies and mortality among patients with rheumatoid arthritis who are treated with abatacept.
PLX3397 is a selective inhibitor of Fms and Kit activity. The objective of this study is to evaluate the safety, pharmacokinetics (PK), pharmacodynamics (PD), and drug-drug interaction (DDI) of orally administered PLX3397 during 2 weeks of dosing in patients with rheumatoid arthritis (RA) who are on maintenance methotrexate. This study is planned to provide data to inform dose selection for a subsequent 12 week dose ranging study in RA.
This is an efficacy and safety study of 3 doses (2.5 mg, 5 mg and 10mg) of tanezumab administered subcutaneously versus placebo. This study will also compare a subcutaneous (SC) administration of 10 mg of tanezumab) with an intravenous (IV) administration of 10 mg of tanezumab. Each person will receive an IV infusion and a SC infusion. The study will last 16 weeks for those who wish to enter a 64-week extension study or 24 weeks for those who do not.
This open-label single-arm study will evaluate the safety, tolerability and efficacy of tocilizumab [RoActemra/Actemra] in patients with moderate to severe rheumatoid arthritis who experience an inadequate clinical response to a stable dose of non-biologic disease modifying anti-rheumatic drugs (DMARD) or anti-tumor necrosis factors (TNFs). RoActemra/Actemra will be administered as a monotherapy or in combination with DMARDs. RoActemra/Actemra will be administered as intravenous infusion at a dose of 8 mg/kg every 4 weeks for a total of 6 infusions. The anticipated time on study treatment is 24 weeks. The target sample size is 50-150 patients.
The purpose of this study is to compare the incidence rates of targeted infections, malignancies and mortality among patients with rheumatoid arthritis who are treated with abatacept and those who are treated with other anti-rheumatic medications.

Phase 3, multicenter, randomized, double-blind, parallel-group, placebo-controlled study to evaluate the efficacy and safety of Certolizumab Pegol (CZP) in subjects with adult onset active and progressive Psoriatic Arthritis (PsA).
