Active clinical trials for "COVID-19"

The purpose of this Clinical trial is to explore the therapeutic benefits of Ivermectin and Doxycycline in different combinations in high risk patients diagnosed with COVID-19.

This is a specimen collection study intended to generate a biological specimen repository of samples from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) naïve adults and adolescents ≥12 years old who will receive locally authorized or licensed COVID-19 vaccines. Approximately 1,000 participants will be enrolled. Plasma and peripheral blood mononuclear cell samples will be obtained either by venipuncture, or by leukapheresis. Serum, RNA, and DNA samples will be obtained by venipuncture. Specimens for mucosal antibody assessments will be collected by nasal swabbing. Biological specimens will be collected from study participants at Baseline prior to the COVID-19 vaccine dose and at timepoints aligned with the study participant's vaccination schedule for a period of up to 1 year following receipt of the initial COVID-19 vaccination.

This is a Phase 2/3, randomized, double-blind, placebo-controlled, multi-center study to evaluate the safety, tolerability, and efficacy of ADM03820 to prevent symptomatic COVID-19 in adult subjects (≥ 18 years of age).

It is unknown whether malaria or malaria treatment affects COVID-19 severity, immune responses to SARS-CoV-2 virus, or viral loads and/or duration of shedding and therewith the onwards spread of SARS-COV-2. An observational cohort study will be conducted in 708 newly diagnosed COVID-19 patient of all ages in western Kenya and Burkina-Faso. They will be enrolled in hospitals with COVID-19 testing facilities from a source population screened for SARS-CoV-2 (N~4,720). Approximately 142 of the 708 COVID-19 patients are expected to be co-infected with malaria. They will be enrolled in the nested malaria treatment trial and randomized to receive 3-days of artemether-lumefantrine (the current standard of care) or pyronaridine-artesunate, a highly effective antimalarial with known antiviral properties against SARS-CoV-2 in-vitro, that is newly registered and being rolled out in Africa. Disease progression will be assessed and nasal swabs and blood samples will be taken during home/clinic visits on days 1, 3, 7, 14, 21, 28, and 42. Patients self-isolating will be phoned daily in between scheduled visits for the first 14 days to assess signs and symptoms. Hospitalisation, self-isolation and home-based care will follow national guidelines. The WHO clinical progression scale and FLU-PRO plus scales will be used to compare disease progression between COVID-19 patients with and without malaria, and by malaria. Other endpoints include seroconversion/reversion rates, chemokine/cytokine responses, T and B cell responses, viral load and duration of viral carriage. Infection prevention and control (IPC), including the use of personal protection equipment (PPE), and measures for patient transport will follow national guidelines in each country. Written informed consent/assent will be sought. The study is anticipated to start in January 2021 and last for approximately 18 months.

This is a phase Ⅱb, single-center, randomized, double-blind, placebo-controlled study, to evaluate the immunogenicity and safety of the recombinant COVID-19 vaccine (Sf9 cells) in the subjects from healthy adults and elderly adults aged 18 years and above (aged 18-59 and 60-85 years) with immunization procedures 0, 21, 42 days and doses 40μg.

The main objective of the study is to evaluate the capacity of a novel nutritional supplement intervention including strains from the species Bifidobacterium longum, Bifidobacterium animalis subsp. Lactis and Lactobacillus rhamnosus, plus vitamin D, zinc and seleniumt) (immune system enhancer, antioxidant and anti-inflammatory capacity) to decrease the viral load by nasopharyngeal smear in patients admitted for COVID-19 coronavirus disease.

The pandemic caused by SARS-CoV-2 is a global emergency present in 6 continents including 66 countries, incurring a shortage of effective and safe therapeutic alternatives that can contribute to reducing the risk of contamination, as well as helping to reduce the viral load of the positive patient. This requires a coordinated, effective and immediate action on the part of governments, companies, academic entities and even at the individual level. In the search for new therapeutic and prevention alternatives, the application of hypochlorous acid (HClO) to the nasal mucosa is proposed, a broad-spectrum and fast-acting antimicrobial solution, whose safety has been proven in preclinical trials. The efficacy of HClO has been tested against enveloped and non-enveloped viruses, reducing virus particles without affecting human cells. This solution could contribute to reducing the viral load and the risk of contamination of patients and professionals. This could have an impact on controlling the COVID-19 pandemic.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the pathogen that causes a coronavirus-associated acute respiratory disease called coronavirus disease 19 (COVID-19), which is spreading all over the world. This virus can cause acute respiratory distress syndrome (ARDS) with a high fatality rate. In this phase I first-in-human clinical trial, healthy volunteers in two dose cohorts will be vaccinated Lyophilized COVID-19 mRNA Vaccine (RH109) The aim of the study is to assess the safety, reactogenicity and Immunogenicity of the candidate vaccine and to characterize its immunogenicity.

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which originated in Wuhan, China, has become a major concern all over the world. Convalescent plasma or immunoglobulins have been used as a last resort to improve the survival rate of patients with SARS whose condition continued to deteriorate despite treatment with pulsed methylprednisolone. Moreover, several studies showed a shorter hospital stay and lower mortality in patients treated with convalescent plasma than those who were not treated with convalescent plasma. Evidence shows that convalescent plasma from patients who have recovered from viral infections can be used effectively as a treatment of patients with active disease. To date, no specific treatment has been proven to be effective. The investigators plan to treat critical Covid-19 patients with hyperimmune plasma.

This 3-arm study compares the effectiveness of an (1) 8-week mindfulness-based intervention, MBCT-R (Mindfulness-Based Cognitive Therapy for Resilience During COVID-19)+CHA MindWell vs. (2) iCBT (internet based Cognitive Behavioral Therapy)+ CHA MindWell vs. (3) CHA MindWell remote monitoring and telephone coaching alone on depressive symptoms as measured over the course of 24-weeks by the computerized adaptive mental health (CAT-MH) interview for depression (CAT-DI). Secondary outcomes include rates and levels of alcohol and drug use, as well as the number of required mental health clinician visits (televisits and in-person visits). Exploratory outcomes include stress-related affect reactivity and salivary inflammatory markers (e.g., interleukin-6).
