Active clinical trials for "COVID-19"

Comparison of the effects of CYT107 vs Placebo administered IM at 10μg/kg twice a week for three weeks on immune reconstitution of lymphopenic COVID-19 patients

The aim of this study is to determine if Povidone iodine (PVP-I) rinses and throat gargles or a PVP-I gel forming nasal spray compared to a placebo (a treatment that has no physical effect to a person) is an effective treatment for patients diagnosed with COVID-19. These patients have been diagnosed with mild/moderate COVID-19 symptoms and sent home for self-isolation. Patients will be instructed to take either of the two treatments or placebo twice daily for two weeks and have follow up visits 2 and 4 weeks after. The participants will also complete study related procedures such as saliva sample collection, and two questionnaires throughout the study period. The investigators hypothesize that COVID 19 positive participants who use either of the Povidone - Iodine treatment will have a reduction in their viral load, develop a negative oral mucosa sample and improve their clinical symptoms.

Evelo will investigate the safety and efficacy of EDP1815 in the treatment of patients hospitalized with SARS-CoV-2 Infection

The purpose of this study is to evaluate the efficacy and safety of intravenous abatacept administered to hospitalized COVID-19 participants with respiratory compromise.

Study Objective: To test if early preemptive hydroxychloroquine therapy can prevent disease progression in persons with known symptomatic COVID-19 disease, decreasing hospitalizations and symptom severity.

The purpose of this randomized, double blinded, placebo controlled study is to assess the efficacy and safety of tofacitinib in hospitalized adult (18-99 years old) patients with SARS-CoV-2 and pneumonia who require supplemental oxygen and have serologic markers of inflammation but do not need mechanical ventilation.

The present test-negative design study aims to estimate the real-world effectiveness of Pfizer-BioNTech BNT162b2 mRNA vaccine on symptomatic SARS-CoV-2 infection and its consequences following a mass vaccination campaign in the city of Toledo in Southern Brazil. Individuals aged 12 years or older who seek the public healthcare system with symptoms suggestive COVID-19 will be enrolled. Participants with a positive polymerase chain reaction (PCR) test for SARS-CoV-2 will be classified as cases, and those with negative PCR test for SARS-CoV-2 will be classified as controls. Cases will be followed-up for a period of one year by means of structured telephone interviews.

The primary objective of the study is to characterize the concentrations of casirivimab+imdevimab in serum over time after a single subcutaneous (SC) administration The secondary objectives of the study are: To assess the safety and tolerability of SC or single administration of casirivimab+imdevimab To assess the occurrence of grade ≥3 injection site reactions and grade ≥3 hypersensitivity reactions, in participants treated with SC doses of casirivimab+imdevimab To assess the immunogenicity of casirivimab+imdevimab

Objective: to evaluate the tolerability, safety and efficacy of inhaled usage of the Recombinant Non-immunogenic Staphylokinase (Fortelyzin®) vs placebo in patients with COVID-19.

This is a 2-part, multi-center, randomized, double-blind, placebo-controlled, phase 2 study designed to evaluate the safety, tolerability, and efficacy of oral varespladib, in addition to standard of care, in patients hospitalized with severe COVID-19 caused by SARS-CoV-2.
