Filter by:Multi-site, first-in-human study to assess safety and efficacy of an active implantable Vagus Nerve Stimulation (VNS) device in 15 adult patients with active moderate-to-severe rheumatoid arthritis who have had an incomplete response or intolerability to at least two different mechanisms of action.
According to World Health Organization (WHO), since December 2016, Brazil is showing a significant increase in cases of yellow fever in humans. In view of this, vaccination is suitable for residents and travelers to the risk area. However, for immunosuppressed patients there is a formal recommendation not to vaccinate with live virus vaccine. On the other hand, the safety and efficacy of the vaccine has been demonstrated in patients with HIV, and safety and seroconversion have also been demonstrated in patients with rheumatic disease who were inadvertently revaccinated for yellow fever. Faced with the impossibility of leaving the high-risk area for some patients the vaccination could be released to only those who have low level of immunosuppression as suggested by some recommendations of medical societies. The availability of a fractional vaccine in the State of São Paulo, which has proved its efficacy, opens the possibility of exposure to a lower number of copies of the virus in the first exposure of immunosuppressed patients, allowing, if necessary, a safer revaccination, after 28 days to obtain of a more effective immunogenic response. The objectives of the study are to evaluate the immune response of the immunization with fractional yellow fever vaccine (neutralizing antibodies) in patients with systemic autoimmune rheumatic diseases residing in a high-risk area. Secondarily, evaluate the possible association between immunogenicity and vaccination with: demographic data, clinical and laboratory activity of the disease in patients with chronic rheumatic diseases, evaluate the curve of viremia and report adverse events. Patients and healthy controls will be vaccinated for yellow fever in the Immunization Center of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC-FMUSP). The patients' screening for exclusion and inclusion criteria will be done at the rheumatology outpatient clinic after medical evaluation. For the controls will be the routine screening of the Immunization Center. The vaccination protocol will be a fractional dose of the yellow fever vaccine on day D0 for both groups. Patients will be evaluated on day D0, D5, D10, D30-4 and D365 and controls only on days D0, D10, D30-45 and D365 for aspartate aminotransferase (AST), alanine aminotransferase (ALT), platelets, urea and creatinine, immunoglobulin M (IgM) by immunofluorescence for Yellow Fever, viremia, autoantibodies.
The primary objective of this study is to evaluate the pharmacokinetics (PK) of filgotinib and its metabolite, GS-829845, in participants with varying degrees of impaired hepatic function relative to matched, healthy controls.
The purpose of the study is to assess whether, in individuals with rheumatoid arthritis, a low-fat, vegan diet improves pain and other subjective symptoms more effectively than a control supplement or a placebo. The principal measure is pain as measured by Visual Analog Scale (VAS) and disease activity as measured by number of painful swollen and tender joints, respectively. The study duration is 36 weeks. This study tests that a low fat, plant-based (vegan) diet free of foods commonly identified as triggers improves mood, using the Center for Epidemiologic Studies Depression Scale-Revised (CESD-R), and the Beck Depression Inventory II (BDI-II).
First, this study will evaluate, in vitro, the cellular composition of the synovial fluid from patient with rheumatoid arthritis, gout or osteoarthritis. Then samples will be test with a new format of bispecific antibody targeting dendritic cells. The production of IL-10 will be the principal criteria of judgment. Production of others cytokines like IL-1B, IL-6, IL-12 and IFN will be checked as well.
This non-interventional study aims to identify key factors that are driving treatment decisions by rheumatologists in the treatment of rheumatoid arthritis (RA) patients starting treatment with Tofacitinib in a real world setting.
This is a phase 2a study to be run in 2-3 countries in European Union involving 5-6 sites. It will enroll approximately 80 patients to ensure 40 randomized with active rheumatoid arthritis. The treatment period is 2 weeks and total study duration per patient is approximately 1 month. The study drugs are AZD9567 40 mg (an oral SGRM) and the comparator is prednisolone 20mg. The primary endpoint is DAS28 including evaluation of 28 joints and C-reactive protein. Safety parameters will also be evaluated and a biomarker program is included for future research.
The purpose of the study is to evaluate the ability of subjects who are already prescribed Certolizumab Pergol therapy and have been self injecting with prefilled syringes for at least the previous three months, to safely and effectively self-inject Certolizumab Pegol (CZP) using the e-Device and to evaluate the post-use structural integrity of used devices and cassettes via visual examination.
To compare the PK profiles of HLX01 and Rituximab in Chinese patients with moderate to severe rheumatoid arthritis.
The purpose of this observational study is to assess the safety and effectiveness of biosimilar Infliximab in patients with rheumatoid arthritis(RA) in Jordan where no visits or intervention(s) additional to the daily practice will be performed
