Active clinical trials for "COVID-19"

Background: Allergic reactions have been reported to occur after vaccination with both the Pfizer-BioNTech COVID-19 Vaccine and Moderna COVID-19 Vaccine. Allergic reactions range from mild to severe and include life- threatening anaphylactic reactions, although no deaths have been reported with either vaccine. This study is designed with two principal aims: To estimate the proportions of systemic allergic reactions to the Pfizer-BioNTech COVID-19 Vaccine and the Moderna COVID-19 Vaccine in a High-Allergy/Mast Cell Disorder (HA/MCD) population, and If the risk in the HA/MCD is demonstrable, to determine whether the proportions are higher in the HA/MCD in comparison to a representative population without severe allergies or mast cell disorders

The aim of the study is to evaluate two differents regimens of corticosteroids (prednisolone versus dexamethasone) on D28 mortality in patients with CoViD 19 pneumonia requiring oxygen supplementation

This study will investigate how ensovibep is distributed throughout the body, the viral clearance and the tolerability of ensovibep in patients with symptomatic COVID-19 disease

This study was an experimental, randomized clinical trial, with a parallel design, with aims were seeing the effectiveness of extracted Psidii guava on white blood cells (WBCs) count, neutrophil, lymphocyte, monocyte, neutrophil-lymphocyte ratio (NLR), high sensitive C reactive protein (hs-CRP), proportion and duration COVID-19 seroconversion subjects compared to controls. One of the herbs standardized that was commonly used in Indonesia is extracted Psidii guava, which is known as a guava leaf extract. Extract Psidii guava contains chemical substances saponins, oleanolic acid, xylopyranoside, flavonoids, quercetin, arabinopyranoside, and Guaijavarin. The Previous study on Psidii guava stated that guava leaves contain lots of flavonoids, especially quercetin. An in vitro study of dengue virus type 2 found that quercetin significantly inhibited the activity of the DEN-2 virus, while other flavonoids looked weaker. On the other hand, in an in vitro test of glycosylated flavonoids from Psidium Geunesse, which is a guava leaf from Brazil, received the use of flavonoids in Psidium Geunesse to inhibit HIV-1 virus activity with a 50% inhibition concentration of about 8.5 μg / ml compared to single active substances. Quercetin with a 50% inhibitory concentration of about 53μg / ml. These flavonoids also inhibited the enzyme reverse transcriptase HIV-1(RT)with an inhibition concentration of 7.2 μM compared to quercetin 0.6 μM single. Another study found that quercetin in Psidii guava inhibits RNA polymerase, which is important in dengue virus replication. In addition, quercetin can inhibit protease enzyme, helicase domain, and viral ATPase enzyme. There is an antiviral effect based on limited in vitro studies but with quite a lot of literature studies, and considering that there are no effective antiviral drugs against COVID-19, especially mild and moderate cases, also considering the length of healing time for patients COVID-19 with the risk of isolation. For a long time with various consequences, researchers tried to examine the effectiveness of extract Psidii guava inpatients COVID-19 at the quarantine location of the West Sumatra Provincial Government. Extract Psidii guava is hypothesized to improve WBCs, neutrophil, lymphocyte, monocyte, NLR, hs-CRP level, to increase proportion and shorten the duration of COVID-19 seroconversion in mild and symptomless cases.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) promotes challenging immune and inflammatory phenomena. Though various therapeutic possibilities have been tested against coronavirus disease 2019 (COVID-19), the most adequate treatment has not yet been established. Among candidate adjunct treatment options, propolis, produced by honey bees from bioactive plant exudates, has shown potential against viral targets and has demonstrated immunoregulatory properties.

This clinical study is aimed at investigating the effects of transcranial direct current stimulation (tDCS) on COVID-19 patients not admitted to the intensive care unit. The tDCS is a non-invasive brain stimulation technique which applies a low intensity electrical current in order to modulate neuronal activity. Patients included will be submitted to a single session with active or sham tDCS, aiming to modulate prefrontal or supplementary motor area (SMA). Evaluation protocol will be performed before and after stimulation to verify the incidence of adverse events related to treatment and whether tDCS would affect measures of executive functioning, mood, anxiety, autonomic response and motor function in COVID-19 patients. We hypothesize the neuromodulation would be a safety, promising treatment to reduce possible impairments in COVID-19 patients.

One investigational treatment being explored for COVID-19 is the use of convalescent plasma collected from individuals who have recovered from COVID-19 (Refs. 1-4). Convalescent plasma that contains antibodies to severe acute respiratory syndrome coronavirus 2 or SARSCoV-2 (the virus that causes COVID-19) is being studied for administration to patients with COVID-19. Use of convalescent plasma has been studied in outbreaks of other respiratory infections, including the 2003 SARS-CoV-1 epidemic, the 2009-2010 H1N1 influenza virus pandemic, and the 2012 MERS-CoV epidemic (Refs. 5-7). Although promising, convalescent plasma has not yet been shown to be safe and effective as a treatment for COVID-19. Therefore, it is important to study the safety and efficacy of COVID19 convalescent plasma in clinical trials. This guidance provides recommendations to health care providers and investigators on the administration and study of investigational convalescent plasma collected from individuals who have recovered from COVID-19 (COVID-19 convalescent plasma) during the public health emergency. This guidance also provides recommendations to blood establishments on the collection of COVID-19 convalescent plasma..

This is a first-in-human (FIH), randomized, double-blind, placebo-controlled, single-center phase I clinical trial of JS026 and JS026 + JS016 Injection. The objective of the study is to evaluate the safety, tolerability, PK profile and immunogenicity of a single intravenous infusion of JS026 and JS026 + JS016 Injection in healthy subjects. In this study, the single ascending dose design will be adopted, JS026 will be administered sequentially from low dose group to high dose group, and each subject can only receive an intravenous infusion at one dose level. Five dose groups (30 mg, 100 mg, 300 mg, 600 mg, and 1000 mg) will be set to receive an intravenous infusion of JS026, and two dose groups (300 mg JS026 + 1200 mg JS016, and 600 mg JS026+ 1200 mg JS016) will be set for JS026 + JS016. The investigational product and placebo will be distributed in each dose group in a ratio of 3:1. Four subjects will be enrolled in each of JS026 30 mg and 100 mg groups, and 8 subjects will be enrolled in each of other dose groups, totally 48 subjects.

The purpose of this trial is to assess the safety, tolerability and treatment effect of the orally administered Caspase-1 inhibitor, belnacasan, for the treatment of patients with mild to moderate COVID-19 and to generate proof of concept for future trials.

The coronavirus disease (COVID- 19) is now a global pandemic that was first reported in China (Wuhan) in December of 2019. Multiple placental abnormalities including fetal and maternal vascular malperfusion have been described in pregnant women infected with (COVID- 19). To date, there are far fewer reports about the specific effects of (COVID- 19) in the newborns delivered for (COVID- 19) positive mothers.
