NCT ID: NCT04477785 Recruiting - Parkinson Disease Clinical Trials

PPMI Clinical - Establishing a Deeply Phenotyped PD Cohort

PPMI
Start date: July 1, 2020
Phase:
Study type: Observational

The Parkinson Progression Marker Initiative (PPMI) is a longitudinal, observational, multi-center natural history study to assess progression of clinical features, digital outcomes, and imaging, biologic and genetic markers of Parkinson's disease (PD) progression in study participants with manifest PD, prodromal PD, and healthy controls. The overall goal of PPMI is to identify markers of disease progression for use in clinical trials of therapies to reduce progression of PD disability.

NCT ID: NCT04437303 Completed - Stroke Clinical Trials

Periprocedural Continuation Versus Interruption of Oral Anticoagulant Drugs During Transcatheter Aortic Valve Implantation (POPular PAUSE TAVI)

Start date: November 25, 2020
Phase: Phase 4
Study type: Interventional

Transcatheter aortic valve implantation (TAVI) is a rapidly growing treatment option for patients with aortic valve stenosis. Stroke is a feared complication of TAVI, with an incidence of around 4-5% in the first 30 days. Up to 50% of patients undergoing TAVI have an indication for oral anticoagulants (OAC) mostly for atrial fibrillation. OAC use during TAVI could increase bleeding complications, but interruption during TAVI may increase the risk for thromboembolic events (i.e. stroke, systemic embolism, myocardial infarction). Recent observational data suggest that periprocedural continuation of OAC is safe and might decrease the risk of stroke. Beside the potential reduction of thromboembolic events, continuation of OAC is associated with an evident clinical ancillary benefit for patients and staff. Since periprocedural OAC interruption not infrequently leads to misunderstanding and potentially dangerous situations, when patients are not properly informed before hospital admission or may experience difficulties with the interruption regimen. Hypothesis: Periprocedural continuation of oral anticoagulants is safe and might decrease thromboembolic complications without an increase in bleeding complications at 30 days

NCT ID: NCT04380987 Recruiting - Covid19 Clinical Trials

Luxembourg Cohort of Positive Patients for COVID-19: a Stratification Study to Predict Patient Prognosis

Predi-COVID
Start date: May 4, 2020
Phase:
Study type: Observational

Predi-COVID is a prospective cohort study composed of people positively tested for COVID-19 in Luxembourg, followed digitally for monitoring participants' health evolution and symptoms at home. Participants will be actively followed for 14 days from the time of confirmation of diagnosis, whether they are at the hospital or at home in isolation or quarantine. Short evaluations will be also performed at week 3 and week 4 and then monthly for a period up to 12 months to assess potential long term consequences of COVID-19. A subsample of 200 participants will be contacted to integrate complementary clinical data and collect samples. The study aims at identifying factors associated with the COVID-19 disease severity. COVID-19 patients with severity criteria will be compared to patients with mild disease managed at home. A deep phenotyping related to the symptoms of the disease as well as biosampling allowing for laboratory-based and computational analytics will be performed.

NCT ID: NCT04379297 Completed - COVID19 Clinical Trials

COvid-19 National Survey for Assessing VIral Spread by Nonaffected CarriErs (CON-VINCE)

CON-VINCE
Start date: April 10, 2020
Phase:
Study type: Observational

CON-VINCE (COvid-19 National survey for assessing VIral spread by Non-affected CarriErs) is a national, monocentric, and longitudinal study aiming to evaluate the spread dynamics of the COVID-19 disease within the Luxembourgish population. Participants who are clinically asymptomatic or present with only mild symptoms will be followed up longitudinally, regularly tested for SARS-CoV-2 by RT-PCR, antibody status, and subjected to an epidemiological, clinical and biological phenotyping to better understand the nature, dynamics of infectivity and spread of the virus in the population. CON-VINCE will also track the psychological and socio-economic impact of long-term containment measures on the general population.

NCT ID: NCT04352231 Completed - Healthy Volunteers Clinical Trials

Luxembourgish Fiber Cohort

Lux-FiCo
Start date: February 22, 2021
Phase: N/A
Study type: Interventional

Many human populations across the world are deficient in the intake of dietary fiber. This decline in fiber consumption parallels an increase in prevalence of a multitude of diseases (e.g. colorectal cancer, multiple sclerosis). A possible link for this association between dietary changes and the diseases could rest in the trillions of commensal gut microbes that digest dietary fibers, provide energy for colonic cells, and modulate the immune system. However, the molecular mechanisms that link fiber deficiency via the activities of the gut microbiome to various diseases have been poorly understood. The investigators previously showed that, in a mouse model with a defined human gut microbiota, removal of fiber from the diet favors proliferation of bacteria that degrade the gut's protective mucus lining. In the proposed project, the investigators aim to translate our findings from mouse studies to humans using a 2x2 crossover study among healthy adults. Forty participants will be randomly assigned to a low- or high-fiber dietary intervention and then, following a washout period to reverse any changes, switched to the other diet type. By employing longitudinal sampling of stool collections, the investigators envision that participants will exhibit increased abundance and activities of mucolytic bacteria when fed a low-fiber diet. The unique selling point of the proposed study involves setting up high-throughput culture collections of mucus-degrading bacteria, whose abundances and activities will be investigated by sequencing and enzymatic assays in stool. Additionally, the investigators will measure inflammatory markers in blood using CyTOF to assess whether short-term fiber deficiency exerts detectable changes in the host immune function. Thus, the proposed dietary intervention clinical trial will help elucidate the role of fiber deficiency in various chronic diseases.

NCT ID: NCT04315948 Completed - Clinical trials for Corona Virus Infection

Trial of Treatments for COVID-19 in Hospitalized Adults

DisCoVeRy
Start date: March 22, 2020
Phase: Phase 3
Study type: Interventional

DisCoVeRy is a randomized controlled trial among adults (≥18-year-old) hospitalized for COVID-19. This study is an adaptive, randomized, open or blinded, depending on the drug to be evaluated, clinical trial to evaluate the safety and efficacy of possible therapeutic agents in hospitalized adult patients diagnosed with COVID-19. The study is a multi-centre/country trial that will be conducted in various sites in Europe with Inserm as sponsor. The study will compare different investigational therapeutic agents to a control group managed with the SoC including corticosteroids and anticoagulants. There will be interim monitoring to allow early stopping for safety and to introduce new therapies as they become available. If one therapy proves to be superior to others in the trial, this treatment may become part of the SoC for comparison(s) with new experimental treatment(s). In previous versions of the DisCoVeRy protocol, remdesivir, lopinavir/ritonavir with or without interferon ß-1a and hydroxychloroquine were evaluated as potential treatments for COVID-19. These treatments have been discontinued based on analyses review by both DSMC/DSMB, the Solidarity Executive Group and the DisCoVeRy steering committee. This version of the protocol, therefore, describes a randomized blinded placebo-controlled trial among adults (≥18-year-old) hospitalized for COVID-19 that randomly allocates them (1:1 ratio) between 2 arms: SoC + placebo versus SoC + AZD7442. Randomization will be stratified by region (according to the administrative definition in each country), antigenic status (positive or negative) obtained from the result of a rapid antigen test on nasopharyngeal swab performed at enrolment and vaccination initiation (yes or no). The primary analyses will be conducted on patients with antigen-positive results. A positive antigenic test is evidence of high viral shedding consistent with a recently started or uncontrolled infection. Overall, the number of antigen-negative patients will be at most 30% of all included subjects. The number of patients with vaccination (partly or fully) will be limited to 20% of all participants, split evenly between antigen positive and antigen negative patients (i.e. vaccinated patients can make up at most 20% of antigene positive patients and 20% of antigene negative patients). Sensitivity analyses will be performed in all patients, stratified by antigenic status and vaccination initiation. A global independent data and safety monitoring board (DSMB) monitors interim data to make recommendations about early study closure or changes to conduct, including adding or removing treatment arms. However, the current version of the protocol does not allow for efficacy or futility analysis, and the ability to add trial arms will be limited by the study being blinded and placebo-controlled during the investigation of AZD7442.

NCT ID: NCT04142437 Recruiting - Clinical trials for Locally Advanced or Metastatic Solid Tumor Harboring an NTRK Gene Fusion

Study to Learn More About the Safety and Effectiveness of the Drug VITRAKVI During Routine Use in Patients With TRK Fusion Cancer Which is Locally Advanced or Spread From the Place Where it Started to Other Places in the Body

ON-TRK
Start date: April 3, 2020
Phase:
Study type: Observational

In this observational study researcher want to learn more about the effectiveness of drug VITRAKVI (generic name: larotrectinib) and how well the drug is tolerated during routine use in patients with TRK fusion cancer which is locally advanced or spread from the place where it started to other places in the body. TRK fusion cancer is a term used to describe a variety of common and rare cancers that are caused by a change to the NTRK (Neurotrophic Tyrosine Kinase) gene called a fusion. During this fusion, an NTRK gene joins together, or fuses, with a different gene. This joining results in the activation of certain proteins (TRK fusion proteins), which can cause cancer cells to multiply and form a tumor. VITRAKVI is an approved drug that blocks the action of the NTRK gene fusion. This study will enroll adult and paediatric patients suffering from a solid tumor with NTRK gene fusion for whom the decision to treat their disease with VITRAKVI has been made by their treating physicians. During the study, patients' medical information such as treatment information with VITRAKVI, other medication or treatments, changes in disease status and other health signs and symptoms will be collected within the normal medical care by the treating doctor. Participants will be observed over a period from 24 to 60 months.

NCT ID: NCT04109131 Recruiting - CNS Metastases Clinical Trials

A Brain Metastases Research Platform to Tackle the Challenge of CNS Metastases in Solid Tumours

BrainStorm
Start date: July 1, 2020
Phase: N/A
Study type: Interventional

Despite some encouraging data, systemic treatment of CNS metastases from solid tumors remains experimental. Better knowledge on the evolving epidemiology and biology of BM are key elements for the development of new treatment strategies and identification of promising therapeutic targets for new compounds. Further biological findings may help to better understand the heterogeneity between the primary tumor and the CNS metastases and to identify new targets for therapy thus improving patients' outcome. In this context, the Oncodistinct network and the Jules Bordet institute propose to build a multidisciplinary Brain Metastases Clinical Research Platform called BrainStorm. The BrainStorm program will focus on patients with newly diagnosed non-CNS metastatic solid tumors with high risk of developing CNS metastases and will allow building a large clinico pathological database for CNS metastases including ctDNA analyzes from CSF samples. Substudies will be proposed at each time-period with the final objective to develop innovative treatment approaches and strategies.
