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.
The objective of this study is to assess the safety and effectiveness of the automatic atrioventricular (AV) delay and interventricular (VV) delay optimization algorithm used in the PARADYM RF SONR Cardiac Resynchronization Therapy with Defibrillation (CRT-D) device (Model 9770) in combination with the SonRtip Lead, which includes a SonR sensor in the tip of the atrial pacing lead, and compatible SmartView programming software. This study will evaluate the effectiveness of the automatic optimization algorithm in increasing the rate of patients responding to the therapy as compared to an echocardiographic optimization method. This study will also evaluate the safety and effectiveness of the SonRtip atrial pacing lead.
The aim of the trial is to test whether adding 6 injections of rituximab to standard "Lymphome malin B" LMB chemotherapy regimen improves the Event Free Survival (EFS) compared with LMB chemotherapy alone in children / adolescents with advanced stage B-cell Non-Hodgkin Lymphoma (NHL) / B-Acute Leukemia (B-AL)(stage III and LDH > Nx2, any stage IV or B-AL).
Phase II trial to determine the efficacy of Dose Adjusted-EPOCH-Rituximab regimen in children and adolescent with primary mediastinal large B cell lymphoma in terms of event free survival.
The purpose of this study is to investigate if 14 weeks of pazopanib therapy prior to surgery (nephrectomy) is of benefit to patients with metastatic renal cancer. Ninety-five patients will be recruited into his study.
This Phase III trial aims to: Explore the impact of pre-treatment information and radiation dose redistribution on locoregional control in patients with locally advanced SCCHN. The dose to the primary tumor with margins, based upon PET and CT information, will be inhomogeneously increased to a tumor dose between 70 and 84 Gy with decreasing dose towards the edges of the irradiated area. To determine the toxicity of combined modality treatment (cisplatin) with standard dose distribution versus combined modality treatment (cisplatin) with adaptive inhomogeneous radiation dose distribution.
This study is designed to compare three different techniques in ablation of paroxysmal atrial fibrillation. Namely, the Medtronic multi-electrode phased radiofrequency ablation system, the Biosense Webster irrigated multi-electrode phased radiofrequency ablation system, and minimally invasive thoracoscopic surgical ablation. The study hypothesis is that surgical and Biosense Webster ablation are non-inferior to Medtronic ablation.
People with brain metastases from melanoma are offered different treatment options after local treatment of their brain metastases via surgery or stereotactic irradiation. Depending on the treating institution and the clinician involved a patient may or may not be offered whole brain radiotherapy (WBRT) after their brain metastases are excised or treated with stereotactic irradiation. This trial seeks to determine if WBRT reduces the spread of brain metastases and lengthens the time to recurrence. The trial also examines the effect of WBRT on quality of life and brain functions such as memory, speech and concentration. Participants will be randomised after local treatment of their brain metastases to either WBRT or observation. 220 people will be recruited from sites in Australia, Norway, the UK, the US and other international sites.
Patients with an ulcerated melanoma with Breslow >1 mm, N0M0 have a significantly higher risk for relapse than patients with a non-ulcerated primary and about a 40-50% chance of developing stage IV disease to which they will almost invariably succumb. In stage I and II patients with an ulcerated primary who have been sentinel node (SN-staged) and found to be SN-negative there is still a 25-30% relapse risk. The purpose of this study is to evaluate the effectiveness and safety when treated with PEG IFN alfa-2b for 2 years as compared to observation (no treatment), administered after adequate surgery has been performed for ulcerated primary cutaneous melanomas.
Evaluate long-term safety and tolerability of tofacitinib in patients with JIA, who have previously participated in tofacitinib JIA studies.
The purpose of this study is to give patients with medullary thyroid cancer either 300mg/day or 150mg/day vandetanib and compare how well each dose affects how their cancer responds. It will also help the investigators understand the side effects of different doses in these patients.
