Active clinical trials for "COVID-19"

Double blinded randomized clinical trial designed to evaluate the efficacy and safety of hydroxychloroquine combined with azithromycin compared to hydroxychloroquine monotherapy in patients hospitalized with confirmed COVID-19 pneumonia.

Delirium and acute neurocognitive impairment are increasingly observed in adult and pediatric patients with COVID-19. Prospective clinical studies combining clinical and laboratory examinations including specific biomarkers of neuroaxonal injury were not performed for COVID-19. The value of biomarkers of neuroaxonal injury was proven in preliminary studies. These biomarkers could thus contribute to the systematic detection of neurocognitive impairment in patients with COVID-19. Due to worldwide increasing numbers of hospitalized patients with COVID-19, biomarkers of neuroaxonal injury are highly valuable to detect and monitor cognitive impairment, especially with regard to limited resources available to perform time-consuming brain imaging. Biomarkers of neuroaxonal injury are therefore not only of great interest to detect neurocognitive impairment but also to quantify the severity of brain injury in patients with COVID-19.

Patients presenting with the coronavirus-2019 disease (COVID-19) have a very high risk of cardiovascular adverse events, including death from cardiovascular causes. Unfortunately, there are no reliable statistics on the frequency and severity of these complications during the index hospitalization. Moreover, the long-term cardiovascular outcomes of these patients are entirely unknown. The investigators aim to perform a registry of patients who have undergone a diagnostic nasopharyngeal swab for SARS-CoV-2 and determine their long-term cardiovascular outcomes.

The purpose of this study is to assess the efficacy and safety of prazosin to prevent cytokine storm syndrome and severe complications in hospitalized patients with Coronavirus disease 2019 (COVID-19).

This is a three-arm randomized trial comparing the efficacy of single agent hydroxychloroquine to the combination of hydroxychloroquine and azithromycin, and to a delayed hydroxychloroquine regimen, which will serve as a contemporaneous Day 1-6 supportive care control, in eliminating detectable SARS-CoV-2 on day 6 following the initiation of treatment in order to determine which regimen is more effective.

A controlled trial of the drug tranexamic acid (TXA) in outpatients who were recently diagnosed with COVID-19. It is hypothesized that TXA will reduce the infectivity and virulence of the virus.

Passive immunization with immunoglobulins is occasionally used as therapy for the treatment of viral infectious diseases. Immunoglobulins are used for the treatment of CMV disease, and is effective as prophylaxis when given soon after exposure to varicella zoster virus, rabies, and hepatitis B virus. Neutralizing antibodies against MERS, SARS-CoV-1 and SARS-CoV-2 have been shown to be present in patients previously infected with MERS, SARS-CoV-1 and SARS-CoV-2 respectively. During the 2003 SARS outbreak in Hong-Kong,a non-randomized study in hospitalized SARS patients showed that treatment with convalescent plasma (convP) from SARS-recovered donors significantly increased the day 22 discharge rate and decreased mortality. A study in non-human primates showed that rhesus macaques could not be re-infected with SARS-CoV-2 after primary infection. With no proven effective therapy against COVID, this study will evaluate the safety and efficacy of convalescent plasma from COVID-recovered donors as a treatment for hospitalized patients with symptomatic COVID-19. The study will focus on patients who tested positive for SARS-CoV-2 in the last 96 hours before inclusion Primary objectives • Decrease overall mortality in patients within COVID disease Study design: This trial is a randomized comparative trial. Patients will be randomized between the infusion of 300mL of convP with standard of care. Patient population: Patients with PCR confirmed COVID disease, age >18 years Donors will be included with a known history of COVID who have been asymptomatic for at least 14 days. Intervention: 300mL of convP Duration of treatment: ConvP will be given as a one-time infusion Duration of follow up: For the primary endpoint: until discharge or death before day 60, whichever comes first. For the secondary endpoints (with separate consent) up to 1 year. Target number of patients: 426 Target number of donors: 100 Expected duration of accrural: 36 months

This is a single arm phase IIa study of convalescent plasma for the treatment of individuals hospitalized with COVID-19 infection. Subjects will be considered as having completed the study after 60 (+/- 3) days, unless consent withdrawal or death occurs first. Interim analysis will be permitted as described in the statistical section 8. The final analysis will be conducted once the last subject completes the day 60 visit or withdraws from the study.

In this study, the investigators propose to administer clazakizumab to patients with life-threatening Coronavirus Disease 2019 (COVID-19) infection manifest by pulmonary failure and a clinical picture consistent with a cytokine storm syndrome. This is a single-center randomized, double-blind, placebo-controlled trial in which 30 patients will be enrolled and randomly assigned in a 1:1 ratio to two study arms and receive clazakizumab at a dose of 25 mg or placebo.

We hypothesize that inhaled steroid therapy and long acting beta 2 adrenergic agonist, widely prescribed in asthma patients, may also have a local protective effect against coronavirus infection, even in patients without asthma. The primary purpose is To compare time to clinical improvement in patients receiving standard of care associated to the combination budesonide/formoterol or standard of care only. Time (in days) to clinical improvement is defined as the time from randomization to an improvement of two points (from the status at randomization) on a seven-category ordinal scale or live discharge from the hospital, whichever came first within 30 days.
