NCT ID: NCT04918745 Active, not recruiting - Clinical trials for Bilateral Vestibular Loss

VertiGO! - Get up and GO! With the Vestibular Implant

Start date: July 1, 2021
Phase: N/A
Study type: Interventional

In the VertiGO! trial 13 participants with bilateral vestibulopathy (BV) and severe sensory neural hearing loss in the ear to be implanted will receive a combined cochlear (CI) and vestibular implant (VI), capable of stimulating both the cochlear and vestibular nerves (CVI). The participants will make use of this combined stimulation during 3 weeks of prolonged use under supervision in a hospital environment. This trial will serve as a proof-of-concept for restoring vestibular function in patients with BV, an as-of-yet untreatable disorder causing severe impairment and discomfort. The aims of this trial are to investigate efficacy and safety of prolonged vestibular stimulation, to identify the influence of different stimulation algorithms, to assess the feasibility of the combined VI/CI device, to develop a VI rehabilitation program and to further build on the fundamental knowledge of vestibular organ stimulation while also taking into account the patient perspective.

NCT ID: NCT04918732 Recruiting - Clinical trials for Cardiovascular Diseases

NAFLD Primary Care

Start date: May 5, 2021
Phase: N/A
Study type: Interventional

Non-alcoholic fatty liver disease (NAFLD) is with 25% the most prevalent liver disorder in Western society and is associated with overweight, obesity, metabolic syndrome (MetS), type 2 diabetes mellitus (T2DM), cardiovascular diseases (CVD) and increased risk of cancer development. NAFLD is defined by a hepatic fat accumulation of more than 5% in the absence of classical causes of steatogenesis (e.g. alcohol and steatogenic drugs). It represents a broad spectrum of clinical entities from non-alcoholic fatty liver (NAFL) to advanced liver disease with hepatic failure. Most of the patients have simple steatosis, however in about 15-30% non-alcoholic steatohepatitis (NASH) develops, which leads to an overall increase in morbidity and mortality due to the progression to fibrosis, cirrhosis and hepatocellular carcinoma (HCC). Patients with NAFLD have no or few, mainly aspecific symptoms; and generally there is a silent progression of simple steatosis to NASH and in the end liver-related morbidity and mortality. Despite the clinical importance and the potential impact on healthcare resources, there is a striking lack of awareness on all levels of NAFLD. Furthermore, little to know data are available concerning the quality of life of NAFLD patients. Additionally, the majority of NAFLD patients are currently not detected due to the lack of non-invasive methods to diagnose NAFLD. Most of these patients, as a first contact in the healthcare system, will be found in the outpatient clinic of the general practitioner (GP). To date, it is not clear what the burden is of NAFLD and related diseases in at risk subjects in primary care. Therefore, identification of NAFLD patients in this cohort will give information on the prevalence in the group of uncomplicated overweight and obesity and those with concomitant cardiometabolic diseases. By early detecting these patients at risk to develop progressive liver diseases and extrahepatic manifestations, it will be possible to intervene and improve health.

NCT ID: NCT04918706 Recruiting - Pulmonary Emphysema Clinical Trials

Allogeneic MSC Treatment for Pulmonary Emphysema

Start date: June 25, 2019
Phase: Phase 2
Study type: Interventional

Rationale: Pulmonary emphysema is a component of Chronic Obstructive Pulmonary Disease (COPD) characterized by chronic inflammation with neutrophils and monocytes mediating the tissue destruction under the regulation of various types of lymphocytes. Bone marrow-derived mesenchymal stromal cells have potential to halt the progressive inflammatory response as indicated by the investigator's pilot study (CCMO NL28562.000.09) . Objective: To determine whether patients with emphysema develop anti-inflammatory and tissue repair responses by treatment with allogeneic bone marrow-derived mesenchymal stromal cells (MSC) from healthy donors. Study design: an explorative double-blind, placebo-controlled randomized (2:1) trial in 30 patients with moderate to severe emphysema who are scheduled for two separate sessions for surgical lung volume reduction (LVRS). The study treatment is intravenous allogeneic MSC or placebo treatment in between the first and second surgical session. Randomisation will allocate 10 patients to receive 2 x 106 /kg body weight MSC in a range of 1.5 x 106 MSC/ kg to 2.5 x 106 MSC/ kg (at a maximum of 200 x106 MSC per study participant) iv (or 5 patients to receive placebo) at week 4 and 3 before the second LVRS, and will allocate 10 patients to receive 2 x 106 /kg body weight MSC in a range of 1.5 x 106 MSC/ kg to 2.5 x 106 MSC/ kg (at a maximum of 200 x106 MSC per study participant) iv (or 5 patients to placebo) at week 12 and 11 before the second LVRS. Main study parameters/endpoints: the study has a co-primary endpoint. First, the difference in expression of CD31 on cells per micrometer alveolar septae present in lung tissue harvested at the second LVRS from patients who received MSC at 3 and 4 weeks prior to LVRS2 or placebo. Second, the difference between MSC and placebo treatment in change in CO diffusion capacity over a period of 3 years following LVRS2.

NCT ID: NCT04916470 Completed - Clinical trials for Heart Failure With Preserved Ejection Fraction (HFpEF) and Diabetes Mellitus, Type 2

Research Study to Look at How Well Semaglutide Works in People Living With Heart Failure, Obesity and Type 2 Diabetes

STEP HFpEF DM
Start date: June 15, 2021
Phase: Phase 3
Study type: Interventional

This study will look at how participants' daily life is affected by their heart failure. The study will also look at the change in participants' body weight. This study will compare the effect of semaglutide (a new medicine) compared to "dummy" medicine on body weight and heart failure symptoms. Participants will either get semaglutide or "dummy" medicine, which treatment participants get is decided by chance. Participants will need to take 1 injection once a week. The study medicine is injected with a thin needle in a skin fold in the stomach area, thigh or upper arm. During the study participants will have talks with the study staff about healthy lifestyle and physical activity. The study will last for about 59 weeks, that is a little more than 1 year. Participants will have 12 clinic visits with the study doctor. - At 6 of the visits participants will have blood samples taken. - At 5 of the visits participants will be asked to fill in a questionnaire - At 4 of the visits participants will have to do a 6-minute walking test - At 3 of the visits participants will have a test to check the heart. - participants will have their eyes checked before or at the start of the study and at the end of the study Women cannot take part if pregnant, breast-feeding or plan to become pregnant during the study period.

NCT ID: NCT04915703 Recruiting - Clinical trials for Bile Duct Obstruction

Flushing of Internalized Percutaneous Transhepatic Biliary Drainage Catheters

FLUSH
Start date: June 1, 2022
Phase: N/A
Study type: Interventional

Percutaneous transhepatic biliary drainage (PTBD) is a drainage method for biliary obstruction. Patients with a PTBD catheter often need multiple re-interventions because of symptoms of catheter obstruction such as pain, jaundice, pruritus, leakage and/or fever. The onset of these symptoms results in hospital visits, opening of the external catheter of an internal external PTBD and re-interventions. The investigators hypothesize that daily flushing of an internal external biliary catheter will increase the time-to-symptom-onset.

NCT ID: NCT04915157 Recruiting - Clinical trials for Spinal Cord Stimulation

Efficacy of Spinal Cord Stimulation in Patients With Refractory Angina Pectoris

SCRAP
Start date: December 21, 2021
Phase: N/A
Study type: Interventional

There are a growing number of patients with refractory angina pectoris (RAP). RAP is defined as a 'chronic condition (> three months) characterized by diffuse coronary artery disease in the presence of proven ischemia, which is not amendable to a combination of medical therapy, angioplasty or coronary bypass surgery'. These patients are severely restricted in performing daily activities due to debilitating angina complaints, leading to a decreased quality of life. Spinal cord stimulation (SCS) is a last resort treatment option for patients with RAP. SCS is a device with a lead located in the thoracic epidural space and an Implantable Pulse Generator (IPG) in the abdomen or buttock that provides neurostimulation. Four possible mechanisms explaining the beneficial effects of SCS on RAP have been described: reduction of pain perception, decreased sympathetic tone, reduced myocardial oxygen demand, and improved coronary microcirculatory blood flow. Research into the effect of SCS on RAP up to date have mainly been observational studies, with only four placebo-controlled randomized controlled trials. All studies confirm that treatment with SCS leads to a reduction in the number of angina pectoris attacks. What is currently not clear, is whether there is a placebo effect as results vary between the studies. One study looked at the effect of SCS in patients with RAP on the reduction of ischemia (using MIBI-SPECT) with no control arm. After 12 months myocardial ischemia was reduced, but not after three months of treatment. Leading to the conclusion that the reduction is myocardial ischemia was not a direct effect of SCS, but rather due to better coronary collateralization. The 2020 ESC guideline 'chronic coronary syndromes' mentions non-existing to promising levels of evidence with regard to treatment options in patients with RAP and concludes that SCS may be considered (Class IIB; level of evidence B). It concludes that 'larger RCTs are required to define the role of each treatment modality for specific subgroups, to decrease non-responder rates and ascertain benefit beyond potential placebo effects'. The aim of the current randomized controlled trial (double-blind, cross-over, placebo-controlled, single center) is to determine if high density spinal cord stimulation, a paresthesia free form of stimulation, leads to a significant reduction in myocardial ischemia (using PET with Rubidium-82 as tracer) in patients with refractory angina pectoris. All patients included in this study will receive an implanted spinal cord stimulator after a positive TENS treadmill outcome and proven ischemia using the imaging modality PET with Rubidium-82 as tracer. Using a cross-over design all patients will have a 6 month period with high density stimulation and 6 month period of no stimulation. Randomization will determine in which order the patient receives these treatments. Both the patient and the treating physicians are blinded for this randomization process. At baseline a 6-minute walking test, the Seattle Angina Questionnaire, the RAND-36 questionnaire, the NRS scale and the CCS class will be performed/filled out. Cross-over takes place at 6 months (switch from high density stimulation to no stimulation or vice versa) prior to which the PET scan is repeated, as well as the 6-minute walking test, the Seattle Angina Questionnaire, the RAND-36 questionnaire, the NRS-scale and the CCS-class. At the end of the study period (12 months) the PET scan is repeated, as well as the 6-minute walking test, the Seattle Angina Questionnaire, the RAND-36 questionnaire, the NRS-scale and the CCS-class.

NCT ID: NCT04913649 Recruiting - Clinical trials for Iron Deficiency Anemia

Intravenous Iron to Treat Postoperative Anemia in Older Cardiac Surgery Patients

AGE-ANEMIA
Start date: September 23, 2021
Phase: Phase 4
Study type: Interventional

Postoperative anemia is common in cardiac surgery with cardiopulmonary bypass. Iron deficiency delays the recovery from postoperative anemia and may negatively affect the postoperative trajectory of cardiac surgery patients. The objective of the study is to determine the effect of treatment of postoperative iron deficiency anemia with intravenous iron on disability 90 days after surgery. This will be evaluated in a randomized placebo-controlled double blind two-center trial in which 310 elective cardiac surgery patients will be included.
