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.
Study design Prospective randomized open labeled multicenter study Hypotheses 1. In asymptomatic patients with ≥ 10% of myocardial ischemia: PCI (Percutaneous Coronary Intervention) with latest generation of drug eluting stents is superior to optimal medical therapy in terms of relative reduction in MACCE (Major Adverse Cardiovascular and Cerebrovascular events). 2. In symptomatic patients with ≥ 5% of myocardial ischemia: PCI with latest generation of drug eluting stents is superior to optimal medical therapy (OMT) in terms of improved life quality measured as an increase of SAQ (Self Assessment Questionnaire) score of 8 points after 6 months. Inclusion Criteria - CTO in native coronary artery - Myocardial ischemia in a territory supplied by CTO assessed by nuclear imaging. - Age ≥18 yrs. - Able to provide written Informed consent and willing to comply with the specified follow-up contacts - Target artery ≥ 2.5 mm Prior to randomization all patients undergo 3 months of OMT. Subsequently the population will be divided into: Cohort A: Asymptomatic (CCS < 2 and SAQ QoL > 60) patients with myocardial ischemia (≥ 10% of LV) in a territory supplied by CTO Cohort B: Symptomatic patients (CCS class ≥ 2 and/or SAQ QoL score ≤ 60 after treating non CTO lesions and after OMT) with Myocardial ischemia (5% of LV) in a territory supplied a CTO Cohort C: patients enrolled but not randomized in cohort A or B Exclusion criteria (for both cohort A and B) - NSTEMI or STEMI within 1 month - Coronary anatomy not suitable for CTO-procedure - Coronary artery disease involving the left main/three-vessel disease with indication for CABG following heart team conference - Life expectancy < 2 years - Severe chronic pulmonary disease (FEV1 < 30 % of predicted value) - Contraindication to dual anti-platelet therapy - Pregnancy - eGFR < 30 mL/min/1.73 m2 - In multi-vessel disease: if it is deemed unsafe to treat the non-CTO lesion first. - Severe valvular heart disease Primary endpoint Cohort A: Composite endpoint of MACCE (all-cause mortality, stroke, any myocardial infarction, clinically driven revascularization*), hospitalization for heart failure or incidence of malignant arrhythmias. *CCS class ≥ 2 and/or QoL score < 60. Same criteria used as for allocation to Cohort B Cohort B: SAQ Quality of Life Assessment after 6 months. Number of patients 1,560 (1200 in cohort A/360 in cohort B Follow up time Cohort A: 5 years Cohort B: 6 months
The CLiFF Study will assess changes in liver function and liver fat in patients with colorectal liver metastases (CLM) undergoing pre-operative chemotherapy before liver resection. There will be no change to the standard treatment for CLM. The change in liver fat will be assessed using novel magnetic resonance techniques and the change in liver function will be measured using a newly-developed fully-licensed breath test to give the most accurate measure of liver function possible. Understanding if these changes are related or reversible will help to understand the relationship between obesity and cancer. This is an important issue, as obesity is now the second most common cause of cancer worldwide.
Study design: Randomised, controlled, multi-centre, open-label, phase III trial (with a single intervention registration phase). Primary Objectives The primary objectives of this study are to determine: - The impact on Depth of Response (DoR: less than VGPR versus VGPR or better) when salvage ASCT conditioning is augmented by the addition of a proteasome inhibitor - The influence of a consolidation and maintenance strategy on the Durability of Response (DuR:PFS) Secondary objectives The secondary objectives of this study are to determine: - Overall survival - Time to disease progression - The overall response rate following ixazomib, thalidomide and dexamethasone (ITD) re-induction - Time to next treatment - Progression-free survival 2 (PFS2) - Duration of response - Minimal Residual Disease (MRD) negative rate post re-induction, post-ASCT and conversion after ITD consolidation - Engraftment kinetics - Toxicity and safety - Quality of life (QoL) Participant population (refer to protocol section 9 for a full list of eligibility criteria). - Relapsed MM (with measurable disease by IMWG criteria) previously treated with ASCT - First progressive disease (PD) at least 12 months since first ASCT, requiring therapy. - ECOG Performance Status 0-2 - Aged at least 18 years - Adequate full blood count and renal, hepatobiliary, pulmonary and cardiac function - Written informed consent Interventions: All participants will be registered at trial entry and will receive re-induction therapy with 4-6, 28-day cycles of ixazomib, thalidomide and dexamethasone (ITD), in order to reach maximum response. Participants who achieve at least stable disease (SD) will be randomised on a 1:1 basis to receive either conventional ASCT (ASCTCon), using melphalan, or augmented ASCT (ASCTAug), using melphalan with ixazomib. All participants achieving or maintaining a minimal response (MR) or better following trial ASCT will undergo a second randomisation to consolidation and maintenance or no further treatment. Participants randomised to consolidation and maintenance will receive treatment as follows: consolidation with 2 cycles of ITD and maintenance with ixazomib until disease progression. Number of participants: 406 participants will be registered into the trial to allow 284 participants to be randomised at the first randomisation (R1) and 248 participants to be randomised at the second randomisation (R2).
The primary objective of this study is to determine whether the Corin Optimised Positioning System (Corin, U.K.) reduces the rate of hip dislocation at one-year post-operatively compared with standard templating in patients undergoing total hip replacement. The secondary objectives of this study are to determine whether the Corin Optimised Positioning System (Corin, U.K.) improves functional outcomes, reduces length of hospital stay, and reduces leg length discrepancy compared with standard templating in patients undergoing total hip replacement.
This study is a Phase I, Randomized, Open-Label, Single Center, Cross-over Study to Investigate the Pharmacokinetics and Safety following a Single Application of Three Different Doses 0.5 gm (0.5 mg estradiol), 0.75 gm (0.75 mg estradiol) and 1.25 gm (1.25 mg estradiol), a Transdermal Estradiol Cream (VML-0203), in comparison to a single dose of EstroGelTM 1.25 gm (1 unit/0.75 mg of estradiol) to healthy post-menopausal women.
The current practice of fasting before cardiac catheterization is not based on any studies. If the procedure is to be delayed ( which is common due to busy catheterization lab), this could result in patient's dis-satisfaction and hypoglycemia. Occasionally, cancellation occur because patients are found to be non fasting ( not following the current protocol). The old data of fasting was extrapolated from procedure done under general anesthesia. Now days, cardiac catheterization is always done under local anesthesia and mild sedation. As a matter of fact, emergency cardiac catheterization done for heart attack patients carries more risk than elective one , and are still done without fasting with no reported complication rate like lung aspiration . The highest level of evidence to change the current practice comes from randomized control study. This study has been designed to challenge the current practice. The patients will be divided into 2 groups: - Fasting group (current practice): Clear fluids up to the time of the procedure and no food for at least 2 hours before the procedure. - Non Fasting Group: clear fluids and food and up to the time of the procedure The investigators' aim is to show that there is no difference with regards to potential complications between fasting (current practice) and non fasting (new practice) groups of patients with less incidence of hypoglycemia and hypotension in non fasting group. In addition, The investigators believe that patient satisfaction will be improved if patients are allowed to eat freely before the procedure and the catheter lab working ability will be maximized as the list can be filled promptly with patient on the waiting list (as fasting is no longer required) if a previously booked patient has to be cancelled in the last minute improving patient experience along with the associated financial benefits.
The aim is to test if dietary supplementation with prebiotics reduces measures of anxiety in healthy human participants with high self-reported levels of anxiety. Study will test for an effect on behavioural, neuroendocrine and brain imaging markers of anxiety.
Given the lack of knowledge on lipodystrophies, the medical and social responsibility for the persons affected by it calls for the monitoring of the progression over long periods of time. Sensible clinical and basic research into rare diseases such as lipodystrophy is only possible in multi-location networks with sufficient case numbers. Also, reliable information on the incidence of certain manifestation patterns, health status, etc. is of utmost importance for health care and health policy in this rare disease. Therefore, the European Consortium of Lipodystrophies (ECLip), an association of European experts on lipodystrophy, has launched a registry (OSSE) for lipodystrophies which is committed to help to improve the research conditions by consolidating this kind of information in a registry.
The primary purpose of this study is to investigate the evolution of Right Ventricular (RV) function before and after left ventricular assist device (LVAD) implantation, using novel echocardiographic quantification of RV size and function in combination with comprehensive hemodynamic, laboratory and clinical parameters. The findings of the study will enhance prediction of early and late development of postoperative right-sided heart failure (RHF) and subsequent mortality and morbidity. The secondary purpose of the study is to combine echocardiographic, hemodynamic, laboratory, and clinical data to define optimal management strategies of RHF after LVAD implantation.
This cohort study (participants with CMT and control participants) has two parts (Part 1: CMT1A cohort; Part2: CMT1B, CMT2A and CMTX1 cohort) and is proposed to take place over 3 years across three sites. Participants with CMT aged 5-60 for potential enrolment in the trial will be identified through the existing inherited neuropathy clinics at each site and control participants will be identified among the unaffected relatives and carers of the participants with CMT. If they show interest in participating, they will be given the relevant Patient Information Sheets, Written Consent forms and/or Assent forms. Half of the participants will be recruited at the UK sites (NHNN and GOSH) and the other half at the US collaborating site. Each participant will be invited to two separate research visits (12 months apart) for which travel expenses (return journey) will be reimbursed. Each research visit is expected to last approximately 3 hours and during it, relevant detailed clinical data will be collected (CMTPedS for participants with CMT aged 5-20, CMTESv2-R for participants with CMT over the age of 10, CMT-HI for participants with CMT over the age of 16) and the participant will also undergo an MRI scan (up to 45 minutes) of the lower limbs (feet and calves or calves and thighs). Two separate neuromuscular MRI protocols with specific sequences will be used for the scans of foot and calf muscles and scans of calf and thigh muscles. Blood samples for plasma NEFL levels will be optional at both research visits for the participants at the UK trial sites; plasma NEFL levels will be processed according to our previously published protocol
