NCT ID: NCT04844554 Not yet recruiting - Covid19 Clinical Trials

Protocol of Assistance to Patients With Covid-19 Submitted to Treatment With HD-tDCS

Start date: April 19, 2021
Phase: N/A
Study type: Interventional

COVID-19 has a variety of symptoms from asymptomatic respiratory dysfunction to death. Considering the pathophysiology of SARS-CoV-2 and its relationship with the neuroimmune system, response, autonomic balance, musculoskeletal and respiratory and neuropsychiatric symptoms presented by patients, the investigators highlight the potential use of non-invasive neuromodulation methods to assess the effectiveness of treating patients with COVID-19, as these techniques can be useful in the management of important clinical aspects in the functional recovery of individuals affected by the disease. The investigators intend to evaluate the effects of HD- tDCS to promote ventilatory weaning in patients admitted to the Intensive Care Unit (ICU) and to improve the respiratory performance of those hospitalized in nursing beds for treatment of COVID - 19.

A Randomized, Double Blind, Placebo-Controlled, Multiple Ascending Dose Phase 2a Study of SLV213 in Ambulatory Individuals Positive for COVID-19

Start date: May 1, 2021
Phase: Phase 2
Study type: Interventional

This Phase 2a trial recruits adult ambulatory patients who have been determined to be COVID-19 positive. The study drug SLV213 will be administered to examine its safety, tolerability and provide assessment of its effect on clinical symptoms of COVID-19. Blood samples will be taken pre-dose and at several time points post-dose for pharmacokinetic (PK) analysis.

NCT ID: NCT04843761 Not yet recruiting - Covid19 Clinical Trials

ACTIV-3b: Therapeutics for Severely Ill Inpatients With COVID-19

TESICO
Start date: April 2021
Phase: Phase 3
Study type: Interventional

This study looks at the safety and effectiveness of different drugs in treating COVID-19 in people who have been hospitalized with the infection and who have acute respiratory failure. Participants in the study will be treated with either a study drug plus current standard of care (SOC), or with placebo plus current SOC.

NCT ID: NCT04842721 Not yet recruiting - Covid19 Clinical Trials

Effect of Hypertonic Saturated Saline Mouth Rinse on Covid-19 Virus in Vivo.

Start date: July 2021
Phase: Phase 2
Study type: Interventional

Sars-Cov2 virus is transmitted through the respiratory route and by direct contact with contaminated surfaces and subsequent contact with nasal, oral or ocular mucosa. Many studies have found that the oral cavity and specifically the saliva may be a high-risk route for SARS-CoV-2 infection. Thus, strategies reducing salivary viral load could contribute to reduce the risk of transmission. Furthermore, studies have shown that SARS-CoV persists for two days in oral mucous membranes before its diffusion to the lower respiratory tract. This offers an interesting preventive and therapeutic window of opportunity for the control of this disease. In addition, Naso-pharyngeal viral load was linked with lung disease severity in a study of 12 patients with pneumonia.**. Some current studies around the world, as listed on ClinicalTrials.gov, are testing the effect of some common mouth rinses/gargles on the Covid-19 viral load, including Chlorhexidine gluconate, Hydrogen peroxide Povidone Iodine, Saline (1.102% w/v, slightly hypertonic) and Alcohol. This study aims to test whether Prolonged Hypertonic Saline Mouth Rinse would reduce/eliminate*** the viral load in the Oro- Naso-Pharyngeal cavity, and could therefore be used as a strategy to reduce transmission risk in clinical and social settings. The investigator hypothesizes that COVID-19-positive participants who use Hypertonic Saline Prolonged Rinse treatment will have an reduction/elimination of their Covid viral load, will develop a negative Covid test 7 days after intervention completion and will improve their clinical symptoms, potentially reducing lung disease severity.

NCT ID: NCT04842305 Not yet recruiting - Covid19 Clinical Trials

Mucosal Immunity in Terms of SARS-CoV-2 Antibodies in Saliva After COVID-19 Infection and Vaccination

Start date: April 2021
Phase:
Study type: Observational

The Primary Objective of This Single-center Study is to Investigate the SARS-CoV-2 Spike Glycoprotein RBD Antibody Concentration in Saliva and Serum in Healthy Non Vaccinated and Non-SARS-CoV-2 Infected, COVID-19 Convalescents, Persons Vaccinated With Pfizer-BioNTech BNT162b2, Moderna mRNA-1273 or AstraZeneca ChAdOx1 nCov-19 AZD1222 Vaccines, and Convalescent COVID-19 Patients That Have Subsequently Been Vaccinated. A Potential Difference in the Immunoglobulin Concentrations of the Pfizer-BioNTech BNT162b2 Vaccine, Moderna mRNA-1273 vaccine and the AstraZeneca ChAdOx1-S Vaccine Will be Uncovered. This Knowledge About the Mucosal Immunity Will be Important for Further Designing of Vaccine Strategies.

NCT ID: NCT04841785 Not yet recruiting - Covid19 Clinical Trials

Long Term Efficacy and Safety of COVID-19 (SARS-CoV-2) Vaccination in Kidney Disease Patients

LESS CoV-2
Start date: April 12, 2021
Phase:
Study type: Observational

Rationale: COVID-19 is associated with severely increased morbidity and mortality in patients with chronic kidney disease stage G4-G5 and patients on dialysis or after kidney transplantation. Therefore, effective SARS-CoV-2 vaccination would be of great clinical importance in these patients. However, SARS-CoV-2 vaccination studies have excluded these patients so-far. Literature data indicate that vaccination may be less effective in these patient groups. Objective: To assess the efficacy and safety of SARS-CoV-2 vaccination in patients with chronic kidney disease stage G4-G5, patients on dialysis or after kidney transplantation during two years follow-up after vaccination. Study design: prospective single center observational cohort study. Study population: - all Dutch patients on dialysis with data registered in the Dutch Dialysis registry (RENINE) - all Dutch patients after kidney transplantation with data registered in the Dutch national kidney transplant registry (NOTR). - All Dutch patients with chronic kidney disease stage G4-G5 registered in the Santeon hospitals. Intervention: After SARS-CoV-2 vaccination according to standard of care, blood will be drawn for antibody response measurements at day 28 and month 6 after 2nd vaccination at by mailer-based finger-prick in 3400 hemodialysis patients, 600 peritoneal dialysis patients, 4000 patients after kidney transplantation and 4000 patients with chronic kidney disease stage G4-G5 Main study parameters/endpoints: The primary endpoint is efficacy of SARS-CoV-2 vaccination determined as: - the incidence of COVID-19 after vaccination. Secondary endpoints are - the antibody based immune response at 28 days after completion of vaccination. - the duration of antibody based immune response at 6 months compared to at 28 days after completion of vaccination. - mortality - adverse events of specific interest according to (inter)national authorities in collaboration with LAREB - presence of HLA-antibodies in dialysis patients on the waiting list for a first kidney transplantation - acute rejection and graft failure in patients after kidney transplantation The incidence of these endpoints will be compared, if applicable, to those: - in the general population who are vaccinated - in patients on dialysis or after kidney transplant who are not vaccinated Within these patient groups endpoints will be compared between recipients of different vaccines.
