Filter by:This study evaluates the safety and therapeutic effects of single-dose human umbilical cord blood mesenchymal stem cells (UC-MSCs) on the adult patients with moderate/severe Rheumatoid Arthritis accompany with anemia or/and Interstitial pulmonary disease. Half of participants will receive UC-MSCs and keep the present medication,while the other half will receive a placebo and keep the present medication.
The aim of this study is to examine the efficacy and adverse events in the following 3 groups in rheumatoid arthritis patients: 1. Sarilumab treatment for 12 months 2. Tocilizmab treatment for 12 months 3. Abatacept treatment for 12 months
Rationale: A wide range of serum trough concentrations is observed in tocilizumab-treated rheumatoid arthritis (RA) patients, while 1 mg/L tocilizumab is sufficient to block systemic interleukin-6 receptor. A substantial proportion of patients has higher serum tocilizumab concentrations and is likely to be overexposed. We expect that patients can at least reduce the dose aiming for a concentration of 5 mg/L without reducing efficacy. Objective: To evaluate the feasibility of the study after 20 weeks of follow-up, this includes the evaluation of the dose-reduction algorithm in tocilizumab-treated patients with RA. Study design: Double-blind randomized controlled pilot study with a follow up of 20 weeks. Study population: Consecutive RA patients that are treated with tocilizumab intravenously every four weeks for at least 24 weeks. Patients are screened for tocilizumab concentration after signing informed consent. Intervention: Patients with a concentration below 5 mg/L will continue the dose. Those patients with a tocilizumab concentration above 5 mg/L are randomly assigned (2:1) to dose reduction or to continuation of the standard care tocilizumab dose. In the intervention group, the precise dose-reduction is calculated per patient in order to achieve a tocilizumab concentration of 5 mg/L (range 4-6 mg/L). Main study parameters/endpoints: The feasibility of the study logistics is evaluated according to the dropout rate and patients opinion about the study. Second, the proportion of patients achieving the targeted tocilizumab concentration after dose reduction is evaluated. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Dose-reduction will lead to lower drug costs and possibly to reduce the risk of adverse events. Since we lower the tocilizumab concentration in a proportion of the patients, risk of a exacerbation of the disease exists. In this case, patients will receive their original dose. Previous studies showed that disease activity is controlled adequately after returning to the standard dose. However, our algorithm is designed to reach concentrations of 5 mg/L (range 4-6 mg/L) and studies showed that 1 mg/L of tocilizumab is sufficient to maintain clinical effect. The expected burden of this study is low, since study visits are planned at the time of infusion and therefore do not take extra time. The additional burden consists of an extra blood sample taken every visit and the fingerprick that is performed once.

The aim of this study is to examine the efficacy and adverse events in the following 3 groups in rheumatoid arthritis patients: 1. Baricitinib treatment for 12 months 2. Biologics treatment for 12 months 3. Tofacitinib treatment for 12 months
This is a phase Ib study to investigate the safety, pharmacokinetics and preliminary efficacy of ginsenoside compound K (GCK) tablets in patients with rheumatoid arthritis. This study is to be run in China involving 10-12 sites. It will enroll approximately 240 patients to ensure 128 randomized with active rheumatoid arthritis. The treatment period is 12 weeks and total study duration per patient is approximately 14 weeks.
This study evaluate the Smart System of Disease Management（SSDM）to improve the treat-to-target(T2T) and the safety of drug in the treatment of rheumatoid(RA). All participants will be randomized in the SSDM group and the control group. The patients in the SSDM group will use the SSDM every month and the control group will receive the conventional therapy.
The objectives of this single site, randomized, crossover study is to evaluate the pharmacodynamic interactions between aspirin, NSAIDs and Coxibs with respect to platelet function, biomarkers of inflammation and endothelial function.
