NCT ID: NCT03782753 Completed - Parkinson Disease Clinical Trials

Molecular Pathology and Neuronal Networks in LRRK2 Parkinson's Disease

Start date: February 15, 2019
Phase:
Study type: Observational

Parkinson's Disease (PD) is a progressive neurodegenerative disease characterized clinically by bradykinesia, resting tremor, rigidity, and postural instability. Little is known about the mechanisms underlying neuronal degeneration in PD and currently, no treatment is available to halt disease progression in PD. The pathophysiological characterisation of phenomena occurring in the time window between the pathological start of the disease and the onset of motor symptoms is crucial to develop potential neuroprotective agents. Several genes have been discovered providing important insights on the pathogenesis of PD. Mutations of Leucine-rich repeat kinase 2 (LRRK2) are associated with 2-5% of all PD cases in North American Caucasians. LRRK2 is an enzyme that in humans is encoded by the autosomal dominant Parkinson's disease-8 (PARK8) gene, which is associated with an increased risk of PD. Clinical and digital biomarkers, blood and cerebrospinal fluid (CSF) biomarkers and molecular positron emission tomography (PET) imaging, with specific radioligands, provide invaluable insights to help understand and characterise disease pathophysiology. The investigators aim to characterize molecular phenomena underlying LRRK2 PD with the hope of providing further insights into possible mechanisms taking place in PD and to help identify targets for disease-modifying therapeutics.

NCT ID: NCT03782727 Completed - Skin Cancer Clinical Trials

ObservAtional Study to Investigate Surgical Site Infection in Ulcerated Skin Cancers

OASIS
Start date: March 12, 2019
Phase:
Study type: Observational

The investigators aim to recruit 311 participants to this study from three UK Dermatology departments. The investigators will invite people with suspected skin cancers whose lesions have a broken surface (also known as ulcerated) who will undergo surgery. This study is being carried out because it is possible that patients with skin cancers with ulceration might be at greater risk of developing a wound infection after surgery. The aim of this study is to determine how many people with ulcerated skin cancers develop an infection of the wound after it has been surgically removed. People with ulcerated skin cancers who will have surgery will be invited to participate in the study. If they agree, a member of the research team will explain the study and consent them to participate in the study. At the time of surgery, information will be collected about the participant, skin tumour and procedure. The participant will be given standardised advice regarding wound care and further care will be as per each centre's 'normal clinical care'. If participants are diagnosed with a wound infection then they will asked to take a 'wound selfie' and share the photo with the research team. The research team will contact the participant via a postal questionnaire which will be sent four weeks after the procedure to determine whether they had any concerns about post-operative infection and whether any action was taken. Additionally, all participants at the University Hospital of Wales will have a surface swab taken from their ulcerated skin cancer and these will be analysed in the Public Health Wales laboratory at the University of Wales, Cardiff. The aim of this aspect of the study is to identify the most common bacteria in ulcerated tumours.

NCT ID: NCT03782662 Completed - Clinical trials for Respiratory Syncytial Virus Infections

A Study to Learn About the Drug-drug Interactions of Sisunatovir in Healthy Adult Participants

Start date: November 7, 2018
Phase: Phase 1
Study type: Interventional

The purpose of this clinical trial is to learn about the interaction of sisunatovir with four medications (midazolam, itraconazole, rifampicin, and verapamil). These medications are known to have specific effects on enzymes and proteins that could influence drug absorption. This study will be conducted in 4 Cohorts: - Cohort 1 will receive midazolam and sisunatovir or placebo, - Cohort 2 will receive Itraconazole and sisunatovir, - Cohort 3 will receive verapamil and sisunatovir, - Cohort 4 will receive rifampicin and sisunatovir. A placebo looks like sisunatovir but does not contain any active medicine in it. This study is looking for health adult participants that meet the following criteria: 1. Caucasians age 18 to 45 years 2. All fertile participants must agree to the use of highly effective contraception 3. Body mass index (BMI) of 18-25.0 kg/m2 4. Male and female participants who are overtly healthy as determined by medical evaluation. This includes medical history, physical examination, blood pressure, pulse rate, standard 12-lead ECG (electrocardiogram), and laboratory tests. This study consists of 2 parts, Part A and Part B. Part A will enroll up to 104 participants. The design of Part B will be determined after the completion of Part A.

Influence of Lens Design on Particulate Exchange in the Post-lens Tear Film

Start date: November 16, 2018
Phase: N/A
Study type: Interventional

This is a 5-visit, controlled, bilateral, randomized, subject-masked, crossover (4 treatments x 4 period), non-dispensing study. Subjects will attend all study visits in their spectacle correction having not worn contact lenses on the day of the visit.

NCT ID: NCT03782376 Completed - Crohn Disease Clinical Trials

Start date: November 19, 2018
Phase: Phase 1
Study type: Interventional

A Phase I, open-label, single centre study investigating the pharmacokinetics, safety and pharmacodynamics of a single dose of teverelix TFA, a gonadotrophin releasing hormone antagonist, via subcutaneous or intramuscular route of administration in healthy male volunteers

NCT ID: NCT03781921 Completed - Bulimia Nervosa Clinical Trials

The Neural Bases of Emotion Regulation in Bulimia Nervosa

Start date: October 30, 2019
Phase:
Study type: Observational

This project aims to explore emotional processing and regulation in individuals with Bulimia Nervosa (BN) with a view to better understand its underlying causes. Previous research suggests that binge eating and purging behaviours may be linked to difficulties with emotions and impulses. However, most of the research has been conducted using self-report methods, despite the fact that these individuals have difficulties identifying and describing their emotions (known as alexithymia), making the use of self-report questionable. This project is the first to use electroencephalography (EEG) as an objective method to disentangle emotional processing and regulation in these individuals. A combination of three tasks and questionnaires will be used to measure various aspects of an emotional response and its link to impulsive behaviours in individuals with BN (N=35) and healthy controls (N=35). This study has the potential to inform future treatment for these individuals.
