NCT ID: NCT04987723 Active, not recruiting - Heart Failure Clinical Trials

A Mechanistic Exploratory Study of AF-induced Cardiac Dysfunction and Symptoms

Start date: January 21, 2022
Phase: N/A
Study type: Interventional

Although the heart rhythm disorder Atrial Fibrillation (AF) affects 2% of the population, the impact it has on an effected individual can be highly variable. Some people are asymptomatic whilst others can experience debilitating symptoms or heart failure (HF)- weakness of the heart muscle. The reason why this variability exists in unknown and how AF actually drives HF is unclear. HF can also be caused by many other reasons and it can be difficult to identify those patients with HF caused by AF versus patients with AF but their HF is due to a different reason. This is important as it would help us to identify those patients most likely to improve their heart function after the treatment of AF and thus gain more from invasive treatments like AF catheter ablation; which is effective at restoring normal heart rhythm but has some risks attached. The investigators suspect the characteristics of the AF, such as how irregularly it makes the heartbeat, can be used to predict who will respond better. Studies of heart cells in the lab as well as animal models have suggested this characteristic may be the cause of AF-induced heart muscle weakness and reduce cardiac output, making it a potential predictor that can be measured. Other potential predictors will be measured during pre-procedural scans and tests too. The investigators will also explore whether there are predictors of which patients gain the most symptomatic benefit and gain insight into why some people develop symptoms of AF, whereas others do not. By studying the structural and functional sequelae of catheter ablation in patients with HF the investigators hope to better understand the relationship between the two diseases.

NCT ID: NCT04981496 Active, not recruiting - Cardiomyopathies Clinical Trials

Novel ICD Arrhythmia Detection Algorithm

Start date: July 6, 2021
Phase:
Study type: Observational

Implantable cardioverter defibrillators (ICD) are used to treat life-threatening heart rhythm disturbances (arrhythmias). They have been proven to reduce the risk of sudden cardiac death; however, there are limitations with current ICDs. Firstly, they may deliver inappropriate therapies (therapies delivered in the absence of life-threatening arrhythmias). Secondly, slower life-threatening arrhythmias may be left untreated because current programming recommendations, designed to minimise inappropriate therapies, rely predominantly on heart rates. Therefore, there is considerable potential to make ICDs safer with more sophisticated ICD algorithms. In this research study the investigators will collect data from participants with newly implanted or existing ICDs whilst they are in induced or spontaneously occurring abnormal rhythms. The data will come from sensors placed on the skin that can measure blood flow or electrical properties of the body. In addition, in 20 participants, the investigators will also collect further data from a small loop recorder implanted under the skin. The investigators will use this data to help develop and validate new methods of reliably identifying life-threatening arrhythmias so that future ICDs deliver therapies when only needed. The research is funded by the British Heart Foundation, and will take place at Hammersmith Hospital over 3 years. The investigators aim to recruit 100 patients in total.

NCT ID: NCT04980872 Active, not recruiting - Clinical trials for PIK3CA-Related Overgrowth Spectrum (PROS)/Proteus Syndrome (PS)

A Study of the Safety and Tolerability in Participants With PIK3CA-related Overgrowth Spectrum or Proteus Syndrome Who Are Being Treated With Miransertib (MK-7075) in Other Studies (MK-7075-006)

Start date: November 2, 2021
Phase: Phase 2
Study type: Interventional

This is a study of the safety and tolerability of oral miransertib (MK-7075) administered to participants at least 2 years of age with phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA)-related overgrowth spectrum (PROS) or Proteus Syndrome (PS). This is an extension of other miransertib studies (MK-7075-002 [NCT03094832] or ArQule CU/EAP [NCT03317366]), and may also enroll participants who are approved for MK-7075-002 but have not yet started miransertib therapy.

NCT ID: NCT04978792 Active, not recruiting - Depression Clinical Trials

Does Cultivating Self-compassion Improve Resilience to Criticism and Improve Mental Health in Adults With ADHD?

Start date: September 23, 2021
Phase: N/A
Study type: Interventional

This study aims to investigate the effect that increasing levels of self-compassion may have on levels of perceived criticism, self-criticism, and mental health of adults with ADHD. A secondary aim of the study is to capture how feasible using an online self-guided self-compassion practice maybe with people with ADHD. Research Questions 1. Does a short self-guided self-compassion intervention increase levels of state and/or trait self-compassion in adults with ADHD over time? 2. Are changes in state and/or trait self-compassion associated with changes in levels of self-criticism or perceived criticism? 3. Are changes in state and/or trait self-compassion associated with improvements in mental health? 4. Are changes in mental health mediated by changes in self-criticism or perceived criticism?

NCT ID: NCT04978493 Active, not recruiting - Crohn Disease Clinical Trials

A Study to Test Whether BI 706321 Combined With Ustekinumab Helps People With Crohn's Disease

Start date: October 4, 2021
Phase: Phase 2
Study type: Interventional

This study is open to adults, aged 18-75 years, with moderate to severe Crohn's disease. The purpose of this study is to find out whether BI 706321 combined with ustekinumab helps people with Crohn's disease. BI 706321 is a medicine being developed to treat Crohn's disease. Ustekinumab is a medicine already used to treat Crohn's disease. Participants are put into 2 groups randomly, which means by chance. One group gets BI 706321 and ustekinumab. The other group gets placebo and ustekinumab. Participants take BI 706321 or placebo as tablets every day. Placebo tablets look like BI 706321 tablets but do not contain any medicine. Ustekinumab is given as an infusion into a vein once at the beginning of the study. After that, ustekinumab is given as an injection under the skin every 2 months. Participants take BI 706321 or placebo in combination with ustekinumab for 3 months. After that, participants receive only ustekinumab for another 9 months. Participants are in the study for about 1 year. During this time, they visit the study site about 13 times. At 3 of the visits, doctors do a colonoscopy to examine the bowel. The results from the colonoscopies are compared between the 2 groups. The doctors also regularly check participants' health and take note of any unwanted effects.

NCT ID: NCT04974892 Active, not recruiting - Pregnancy Clinical Trials

Aspirin and Neutrophils in Preeclampsia

Start date: April 1, 2022
Phase:
Study type: Observational [Patient Registry]

The exact mechanisms by which aspirin prevents the development of preeclampsia in high-risk patients are currently not fully known. Furthermore, a small proportion of high-risk patients who are on low-dose aspirin (LDA) still go on to develop preeclampsia (PE). This longitudinal observational study will assess the immune profile in participants who are taking low dose aspirin (LDA) in pregnancy. As part of routine care, patients at high risk of developing preeclampsia are treated with LDA from 16 weeks gestation. The study will be conducted at Barts Health National Health Service (NHS) Trust. The study population will comprise of 2 groups of participants: 1. Those who respond to LDA and do not develop preeclampsia (responders) 2. Participants who do not respond to LDA and develop preeclampsia (non responders) Participants will be consented at their booking appointment. Participants will be eligible if they have a singleton pregnancy and are aged over 18 years. They will have an additional blood sample taken at 12, 20, 28 and 36 weeks gestation. The blood samples will be tested to assess immune cell function, metabolism and genetics. This will identify cumulative changes in immunobiology at key time points in pregnancy.

NCT ID: NCT04973163 Active, not recruiting - Clinical trials for Solid Tumors, KRAS Mutation

A Study to Test Different Doses of BI 1823911 Alone and Combined With Other Medicines in People With Different Types of Advanced Cancer With KRAS Mutation

Start date: August 3, 2021
Phase: Phase 1
Study type: Interventional

This study is open to adults with different types of advanced or metastatic cancer (including lung cancer, colorectal cancer, pancreatic cancer, and bile duct cancer). This study is for people for whom previous treatment was not successful or no treatment exists. People who have a tumour with a KRAS mutation can participate in the study. A KRAS mutation makes tumours grow faster. BI 1823911 and BI 1701963 are medicines that may turn off KRAS, each in a different way. In this study, BI 1823911 is given to people for the first time. The purpose of this study is to find the highest dose of BI 1823911 that people can tolerate when taken alone and together with BI 1701963. The most suitable dose is used to find out whether BI 1823911 alone and in combination with BI 1701963 can make tumours shrink. Participants can stay in the study as long as they benefit from treatment and can tolerate it. During this time, participants take tablets of BI 1823911 alone or in combination with BI 1701963 once a day. The doctors regularly monitor the size of the tumour. Doctors also regularly record any unwanted effects and check participant's health.
