Clinical trials

What are the study aims? To understand more about eating habits and age-appropriate food/drink portion sizes of children aged 6 months-5 years old, and how this affects their growth and dental health. Why is this research important? Healthy diets in early years are important for growth and development. However, clear guidance for parents on what and how much children should eat is missing due to lack of up-to-date information. What will the investigators do? Information will be collected at two time points. At baseline, parents/guardians of children aged 6 months-4 years from Leeds, Doncaster and East London will complete questionnaires about their child's sociodemographic information and food intake. They will be asked to record what their child eats for three separate one-day periods using an online system called 'myfood24'. Parents will also attend one in-person session for measuring their child's length/height, weight, and waist circumference. At follow-up one year later, parents/guardians will complete surveys again, with another in-person session to look at growth and assess dental health. What do the investigators expect to achieve and what happens next? They want to understand how growth and dental health are influenced by nutrient intakes, dietary patterns, and portion sizes for key food groups. They will also identify how much of different foods children should be eating, and whether commercial foods and sweet drinks are relevant. They will explore which dietary factors can support healthier children; and how low intakes of key foods or vitamins/minerals in vulnerable groups could be redressed. The study will provide unique information, allowing for development of recommendations for parents and policy-makers on age-appropriate portions, on achieving good nutrition in UK children and within special dietary groups, and on dietary considerations in caring for children's teeth.

iFIT is a trial for newly diagnosed transplant-ineligible patients with the bone marrow cancer myeloma. These patients are generally older and have a lower level of fitness than others. Patients can take part if their doctor would otherwise recommend the standard NHS treatment daratumumab, lenalidomide and dexamethasone (DRd). After six months of DRd, the subsequent treatment a patient receives in iFIT is based on two factors: the patient's fitness level and treatment response. The trial compares different treatment strategies to determine whether outcomes can be improved for specific patient groups.

Chronic musculoskeletal (MSK) pain affects an estimated 20-33% of the global population and is frequently associated with autonomic nervous system dysfunction, characterised by symptoms such as orthostatic intolerance, palpitations, gastrointestinal dysmotility, and fatigue. Conventional treatments often fail to address this autonomic component, limiting their effectiveness. This pilot study investigates whether non-invasive vagus nerve stimulation (nVNS) using the gammaCore Sapphire device can reduce autonomic symptom severity and improve pain in adults with chronic MSK pain and confirmed autonomic dysfunction. RESTORE-MSK is a randomised, single-blind, sham-controlled, crossover pilot study. Twelve participants with chronic MSK pain (lasting 12 weeks or longer) and autonomic dysfunction (COMPASS-31 score of 17 or more) will be recruited from musculoskeletal clinics at Chapel Allerton Hospital, Leeds. Participants will be randomly allocated to receive either active nVNS or sham stimulation first, followed by a 2-week washout period, then crossover to the alternative treatment. Each treatment period lasts 14 days, with participants self-administering the device twice daily (morning and evening). The primary outcome is change in autonomic symptom severity measured by the Composite Autonomic Symptom Score-31 (COMPASS-31). Secondary outcomes include physiological response to the NASA Lean Test, pain severity and interference (Brief Pain Inventory), anxiety and depression (Hospital Anxiety and Depression Scale), quality of life (EQ-5D-5L), intervention acceptability, and recruitment feasibility. This pilot study aims to establish feasibility and proof of concept for a larger randomised controlled trial investigating nVNS as a non-pharmacological treatment option for chronic MSK pain with autonomic dysfunction.

This work will examine if a technique called Transcutaneous Spinal cord stimulation (tSCS), when used with concurrent specific arm and hand exercises, helps improve arm and hand movements in CYP with HCP. Does Transcutaneous Spinal Cord Stimulation (tSCS), when combined with specific arm and hand exercises, improve upper limb function in children and young people (CYP) with Hemiplegic Cerebral Palsy (HCP)? -To determine the feasibility and effectiveness of Transcutaneous Spinal Cord Stimulation (tSCS) combined with targeted arm and hand exercises in improving the upper limb function in children and young people with Hemiplegic Cerebral Palsy (HCP).

The goal of this clinical trial is to learn if a rehabilitation application on a smartphone, an app, can be used by adults who have had a stroke. The main questions it aims to answer are: Are people who have had a stroke able to use the app? Is the app useful for people who have had a stroke? Will the app adapt to the needs of the person recovering from a stroke? Researchers will compare the app to the usual rehabilitation a person receives after a stroke to see if the app can be used as part of a person's rehabilitation. Participants will: Use the app every day for 6 weeks Have an assessment with a rehabilitation research doctor before starting using the app and after completing using the app Keep a diary of the exercises that they do using the app

The goal of this clinical trial is to learn if the FIND HF algorithm detection rates of heart failure during testing are higher amongst participants identified as high FIND-HF risk compared to those identified as low risk in a population identified as at risk of undiagnosed heart failure. The main questions it aims to answer are: * Are people who are identified as high risk by the FIND-HF tool more likely to be diagnosed with heart problems during testing than those identified as low risk? * Are people identified as high risk by the FIND-HF tool more likely to show signs of heart problems during testing than those identified as low risk?? Researchers will compare patients in the high risk and low risk groups to see if more patients are detected with asymptomatic heart failure in the high risk group compared to the low risk group. Participants will attend one visit at a local clinic where they will undergo an NT proBNP blood test which indicates heart failure and an echocardiogram to evaluate the heart's chambers, valves and overall function to help diagnose various heart conditions.

The present investigation is a non-randomised, observational study involving an unselected but highly phenotyped cohort of patients undergoing pacemaker or defibrillator implantation from whom a small sample of fat and muscle will be taken from the operation site, and, in a subgroup, from the thigh muscle. A sample of blood wil also be taken from the vein of the heart, a peripheral vein and the artery at the wrist during the procedure at different heart rates and pacing modes, to describe how heart rate and heart contraction power relate to cardiac and peripheral metabolism. The coded blood and tissue samples and anonymised clinical data will be stored in a Human Tissue Authority-approved freezer until analysis. Following the procedure, during routine visits, patients' left ventricular force frequency relationship will be assessed using cardiac ultrasound and a non-invasive cardiac monitor to further phenotype the severity and progression of their heart function over 6 months. For most patients, their involvement will end at that point although they will be monitored through electronic health records on an annual basis from that point forward for up to 5 years after the end of the study (for up to ten years after that point) to gain information on the prognostic value of the metabolic and haemodynamic testing. The present investigation will allow the investigators to advance the understanding of heart-muscle crosstalk with the goal of developing targeted interventions that could open new treatment avenues.

CONCORDE is a multi-institution, multi-arm, Phase IB study that will determine the recommended phase II dose (RP2D) and safety profiles of different DNA damage repair inhibitors (DDRis) when given in an open label fashion in combination with fixed dose curative intent radiotherapy (RT) in patients with stage IIB/IIIA/IIIB NSCLC, followed by up to 12 months of consolidation durvalumab immunotherapy in selected study arms. The RP2D will be evaluated by incorporating the number of observed dose limiting toxicities (DLTs) into a time to event continuous reassessment method (TiTE- CRM) model within each of the experimental arms. TiTE-CRM is used here to take into account longer-term toxicities up to 13.5 months post start of radiotherapy and use these to inform dose escalation decision making.

Respiratory disease affects one in five people and is a leading cause of global morbidity and mortality. Chronic obstructive airways diseases encompass conditions characterised by expiratory airflow limitation, exertional dyspnoea, activity limitation and impaired quality of life. The most common conditions include chronic obstructive pulmonary disease (COPD), asthma, bronchiectasis, cystic fibrosis and primary ciliary dyskinesia. In recent years, there has been concerted effort in the scientific and respiratory medicine community to improve the diagnosis and management of chronic obstructive airways diseases using personalised or precision medicine (i.e., tailoring therapies and interventions according to specific "treatable traits") and identifying phenotypes or endotypes using validated biomarkers. To date, however, research in this setting has primarily focussed on people with COPD and asthma, with limited studies in other forms of chronic obstructive airways diseases. The aim of this study is therefore two-fold; first, to compare pulmonary physiology (i.e., large and small airway involvement) and extra-pulmonary manifestations across the spectrum of chronic obstructive airways, and second, to determine how disease-specific treatable traits associate with physical activity and health-related quality of life.

A multi-centre observational study recruiting prospective and retrospective cohorts of patients with polymyalgia rheumatica (PMR) and giant cell arteritis (GCA). The primary aim is to find genetic determinants of GCA and PMR susceptibility, in order to yield novel insights into disease pathogenesis. A subset of the retrospective cohort is also enrolled in a post-marketing surveillance registry of patients eligible for, or receiving tocilizumab, to treat their relapsing or refractory GCA.

This will be an observational study to explore differences in pathophysiology between groups of people with and without heart failure (HF) (reduced and preserved ejection fraction) and with and without diabetes mellitus (DM) with a particular focus on cross-talk (fat, muscle, vascular tissue and the heart). The investigators will invite 600 people to partcipate (100 with HFrEF+DM, 100 with HFpEF+DM, 100 with HFpEF-DM, 100 with HFrEF-DM, 100 with DM, 100 without either HR or DM). Special heart scans, exercise testing, blood testing, testing of the automatic nervous system will be performed and in some, samples of fat and muscle and endothelial cells will be collected. These data will be used to create a cohort of well phenotyped patients with a variety of comprehensively collected clinical information, a cell atlas, and a comprehensive assessment of metabolomics, proeomics and cross-talk in between tissues, allowing comparisons between each group.

Chronic cough is a common and debilitating condition that affects up to 10% of the global population. The health impact of chronic cough is multifaceted and manifests both physical and psychological symptoms including syncope, chest pain, lethargy, depression and anxiety. It is now also recognised that chronic cough often leads to social isolation and may impact an individual's ability or confidence to undertake routine daily tasks / lead an active lifestyle. The primary aim of this study is therefore to characterise the impact of unexplained chronic cough on the ability to undertake daily activities - i.e., determine whether individuals with chronic cough exhibit impaired levels of physical activity during usual daily living when compared with healthy age, gender and BMI matched controls. A secondary aim is to assess the short-term impact of high-intensity exercise on cough (i.e., determine whether an acute bout of exercise alters cough frequency and/or severity).

In pilot studies the investigators have shown that subcutaneous adipose tissue (SAT) from patients with reduced ejection fraction heart failure (HFrEF) and type 2 diabetes mellitus (T2DM) is dysfunctional. Endothelial cells from the adipose tissue from these patients are senescent and have deleterious effects on healthy human subcutaneous adipocytes, including increasing expression of IL-6 (gene and protein) and reducing glucose uptake. Digoxin, a well-established treatment for HFrEF, selectively clears these senescent endothelial cells and prevents adipocyte dysfunction. This study will examine the effect of digoxin on adipose tissue on the burden of senescent cells.

The investigators have demonstrated that they can reliably identify an optimum heart rate range for contractility of the left ventricle in patients with chronic heart failure (CHF). They have also demonstrated in an acute cross-over and a small parallel group feasibility study that keeping the heart rate in this range (versus standard rate-response programming) in patients with CHF is associated with increased exercise time on a treadmill (around 60s or 10%). They now want to explore in a randomised, placebo-controlled 3-arm parallel group trial whether optimal programming versus standard rate-response programming versus no rate-response programming for 6 months leads to appreciable improvements in exercise time and quality of life, while having no adverse effects on left ventricular function and battery longevity and what the mechanisms of this might be. 450 patients with CHF and a pacemaker will undergo the non-invasive echocardiographic assessment to establish the force frequency relationship and the optimal heart rate for contractility. They will then perform a treadmill walk test, complete quality of life questionnaires and be offered the opportunity to participate in a series of mechanistic substudies. They will then be randomised to optimal rate-response settings, standard rate response settings or no rate-response settings and followed up at 6 months at which point the tests will be repeated.

The aim of this feasibility trial is to determine if it is safe and feasible to treat oral health diseases in people with haematological cancers before they start their chemotherapy to reduce complications and disruption to planned chemotherapy dose or schedule.

The RO-PIP trial aims to determine the feasibility of recruitment to a trial randomising patients to salvage ultra-hypofractionated external beam radiotherapy or high dose rate brachytherapy and provide prospective data on patient recorded toxicity outcomes that will inform a future phase III trial.

VINDICATE 2 will be a randomised, placebo-controlled, parallel group, double-blind study of vitamin D versus placebo in otherwise optimally-managed patients with CHF due to LVSD and vitamin D deficiency (\<50nmol/L). The intervention will be a daily dose of 4000IU (100µg) per day or matching placebo for a minimum of 2 years and a maximum of 4 years.

Diabetic kidney disease (DKD) is a common complication of diabetes, and is now the most common form of chronic kidney disease. DKD is the leading cause of kidney disease requiring dialysis or kidney transplantation, and its global incidence and prevalence have reached epidemic levels. While the risk of developing DKD can be ameliorated by tight blood glucose and blood pressure control, it is not fully preventable and once established DKD cannot be cured. Therefore many patients are left with poor and worsening health and with increased mortality risk. Developing new ways to treat DKD requires healthcare professionals to be able to identify those patients most in need of treatment. One promising approach for identifying patients that are at risk is the use of imaging measurements (called "biomarkers") derived from Magnetic Resonance Imaging (MRI) and Ultrasound (US) of the kidneys. Evidence from early studies shows that such imaging biomarkers can identify underlying problems in DKD such as blood supply, oxygen supply, kidney scarring and kidney function, in ways that are better than those currently available. The investigators think that imaging biomarkers will improve the identification of patients who are likely to decline from DKD in the short term. The changes found by imaging may even happen before effects on the blood and urine. The investigators plan to test this hypothesis by performing a study observing 500 patients with early stage DKD, recruited in 5 sites across Europe. All patients will have detailed assessment at the start of their involvement, including clinical assessment, blood and urine samples, and MRI and US scans. The investigators will look at whether imaging biomarkers are associated with other measures that predict progression in DKD, and follow patients every year for 3 years (4 years total study participation) to see if the imaging biomarkers predict worsening DKD.

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).
