Active clinical trials for "Spondylitis, Ankylosing"

This observational study will be a documentation of the prescribing and administration practices of Enbrel® and their impact on ankylosing spondylitis patients outcome in a real life setting.

The primary objective of this cross-sectional observational real life study is to investigate the patient reported adherence to PPI, when prescribed as prevention of NSAID associated GI Ulcers to patients prescribed a NSAID. Patients included have Osteoarthritis, Rheumatoid Arthritis or Ankylosing Spondylitis. Adherence will be assessed by patient questionnaires.

The participants included in this observational study will be drawn from a research database containing claims and enrollment data for members of a large, geographically diverse US health plan.The objective of this study is to estimate the rate of serious infections, tuberculosis, malignancies, and other outcomes in rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis patients treated with golimumab, anti-tumor necrosis factor (TNF) biologics, non-anti-TNF biologics, or systemic non-biological treatments.

This is an observational study aiming to study the prevalence and risk factors for osteoporosis and vertebral fractures in patients with ankylosing spondylitis attending three Rheumatology clinics in Western Sweden.

Ankylosing spondylitis (AS) is a chronic inflammatory disease that affects the joints between the vertebrae of the spine and the joints between the spine and the pelvis. The purpose of this study is to collect information and blood samples from patients with AS and their relatives for use in genetic studies.

Long term data on efficacy and safety of anti-TNF treatment with infliximab in patients with ankylosing spondylitis (AS) beyond 5 years is lacking. These data are important because patients with AS usually are younger and withdrawal of anti-TNF therapy in these patients almost always leads to a disease relapse. Furthermore it is still unclear whether long term anti-TNF treatment in AS patients can inhibit radiographic progression. Patients who participated in the EASIC and the DIKAS trial respectively who were treated with infliximab within these studies for 7 and 10 years respectively are followed up by using clinical outcome parameters every 6 months assessing efficacy and safety of long term treatment. Furthermore radiographs of the spine, if done for clinical indication, are analyzed. It is hypothesized that anti-TNF treatment with infliximab is effective and safe over a time period of 9 and 12 years respectively and that long term anti-TNF therapy may inhibit radiographic progression of the spine.

In Canada and worldwide there is a need for updated independent real-world comparative effectiveness and safety data related to biologic drugs including biosimilar drugs. Biosimilar drugs hold potential to improve access to needed therapies at reduced cost enabling savings to be reallocated to other needs. However updated real-world evidence on comparative effectiveness and safety of biosimilar drugs is lacking. Investigators aim to demonstrate feasibility of creating network of clinical cohorts and other resources to provide real-world information on use of biosimilar drugs in Canada. The core revolves around clinical datasets but investigators will complement with other data sources. Investigators will review data from National Prescription Drug Utilization Information System database that contains prescription claims-level data collected from publicly financed drug benefit programs in different provinces to conduct an environmental scan of the use of biosimilars and respective legacy drugs and other anti-Tumor Necrosis Factor agents covered by provincial drug plans from 2014-2017. Initial analysis will help to confirm that use of biosimilars is lower than corresponding legacy drugs. Biologic drugs are relatively new and expensive drugs; biosimilar medicines are similar to original biologic drugs but cost less. If patients receive biosimilar drugs rather than originator biologics healthcare systems may be able to save money. Those savings can be used for other health care needs to benefit more Canadians. However investigators do not have detailed information on safety and effectiveness of these biosimilar drugs. The aim of study is to compare safety and effectiveness of biosimilar drugs to originator biologic drugs. Investigators will study patients with inflammatory rheumatic diseases (RA and AS) and Inflammatory Bowel Disease (CD and UC) and across Canada on these drugs. Primary focus is on patients without history of biologic drug use but investigators will also study patients switching to biosimilar drug from an originator biologic drug. Investigators will measure how long patients stay on treatment, if patients require new treatment, if the patients' disease control improves and occurrence of side effects such as infection that could be related to these drugs.

The purpose of this prospective cohort study is to evaluate the influence of serum drug levels and development of anti-drug antibodies on clinical response to anti-TNF agents in ankylosing spondylitis(AS) treatment. Secondary aims are to assess the demographic, clinical and laboratory variables associated with the development of anti-TNF drug antibodies at baseline or disease course and to reveal the impact of anti-drug antibodies on long-term efficacy or safety in particular drug survival in AS patients treated in daily clinical practice.
