There are about 25435 clinical studies being (or have been) conducted in United Kingdom. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Eosinophilic Esophagitis (EoE) is a chronic inflammatory disease of the esophagus affecting children and adults. The most frequent symptoms are swallowing difficulties and thoracic pain. The disease has first been described in the 1980s and is found with rapidly increasing frequency mainly in industrialized countries. The factors that lead to EoE are until now incompletely understood, of importance, the disease is found more frequently in men and patients suffering from allergic diseases (e.g., Asthma). So far there exists no activity index to define the severity of EoE; such an index is urgently needed for future clinical trials to determine the efficacy of current and future therapies. The investigators' 3-year project, carried out in cooperation with international EoE experts, aims at the development of an activity index for adult and pediatric EoE patients that will be used in future clinical trials as well as observational studies.
RATIONALE: Studying genes in samples of blood and/or tumor tissue from patients with cancer may help doctors identify biomarkers related to cancer. PURPOSE: This research study is looking at blood and/or tumor tissue samples from patients with ductal carcinoma in situ and blood samples from healthy volunteers.
The presence of scar within heart muscle can act as a substrate for abnormal rhythm problems and lead to the developement of heart failure Clinical significance Correlation with biomarkers and genetic markers
Patients with rheumatoid arthritis are at risk of developing permanent joint damage and disability. This study hopes to identify the most effective way of using existing arthritis medication to minimise the chances of developing permanent disability. Patients will have their arthritis activity assessed using an ultrasound machine. If there is still evidence of active arthritis the participant's arthritis medication will be increased until the arthritis is in remission. The effectiveness of this approach will be compared to the traditional method of assessing arthritis using clinical examination. Furthermore, it is extremely important to identify those patients most at risk of aggressive disease. The investigators hope to produce a more accurate measurement of disease prognosis by examining the relationship between a series of blood tests and how well controlled rheumatoid arthritis appears after 18 months of therapy. Some patients will also be asked to donate samples of joint fluid and joint lining for additional analysis.
The Increlex® Global Registry is a descriptive, multicenter, observational, prospective, open-ended, non interventional, post-authorisation surveillance registry. The main purpose of this global registry is to collect, analyse and report safety data during and up to at least 5 years after the end of treatment in children and adolescents receiving Increlex® therapy for SPIGFD according to the locally approved product information.
RATIONALE: Studying samples of blood in the laboratory from patients with cancer receiving dactinomycin may help doctors learn how dactinomycin works in the body and how patients will respond to treatment. PURPOSE: This laboratory study is evaluating the pharmacokinetics of dactinomycin in young patients with cancer.
RATIONALE: Studying tissue and blood samples from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients respond to treatment. PURPOSE: This laboratory study is evaluating DNA to see how well it predicts response to treatment in patients with stage I, stage II, stage III, or stage IV ovarian epithelial cancer.
RATIONALE: Collecting and storing samples of tumor tissue from patients with soft tissue sarcoma to test in the laboratory may help the study of cancer in the future. PURPOSE: This laboratory is collecting tissue samples from patients with soft tissue sarcoma of the arms, hands, legs, or feet treated on clinical trial CRUK-VORTEX.
RATIONALE: Studying samples of blood and bone marrow in the laboratory from patients at risk of developing myelodysplastic syndrome may help doctors learn more about changes that occur in DNA and identify biomarkers related to disorders of the blood and bone marrow. PURPOSE: This research study is looking at biomarkers in patients at risk of developing myelodysplastic syndrome or other disorders and in healthy participants.
RATIONALE: Collecting and storing samples of sputum and tissue to study in the laboratory may help doctors identify biomarkers related to cancer. PURPOSE: This research study is looking samples of sputum and tissue from lung cancer patients, participants at high risk for developing lung cancer, and from healthy volunteers (both smokers and non-smokers).
