Active clinical trials for "COVID-19"

An AstraZeneca-sponsored observational, electronic healthcare record (EHR)-embedded retrospective cohort study to assess the real-world effectiveness of EVUSHELD against SARS-CoV-2 infection, COVID-19-related hospitalization, and other COVID-19 related outcomes in the total EUA-eligible patient population in the University of Pittsburgh Medical Center (UPMC) Health System.

To determine whether a strategy of adding venovenous ECMO to mechanical ventilation, as compared to mechanical ventilation alone, increases the number of intensive care free days at day 60, in patients with moderate to severe acute hypoxic respiratory failure.

At the University of Iowa, the investigators led a multicenter randomized clinical trial comparing standard prophylactic dose to intermediate dose enoxaparin in hospitalized patients with COVID-19 (NCT04360824). As part of an exploratory biomarker component of this trial, blood samples were collected from hospitalized COVID-19 patients at enrollment and weekly for up to 30 days of hospitalization. The pilot results, as well as reports from other groups, demonstrate increased potential for thrombin generation in the plasma of COVID-19 patients. In particular, in the COVID-19 patient cohort enhanced thrombin generation potential persisted for at least 30 days of hospitalization. The investigators now propose to explore the mechanistic roles of activation of blood cells (such as platelets and neutrophils) and products of cellular activation as mediators of enhanced thrombin generation in patients with COVID-19. The study design will be a longitudinal cohort study, which will allow for the determination of the time course of enhanced thrombin generation potential in relation to clinical outcomes and changes in markers of cellular activation in serial samples obtained from COVID-19 patients for up to 3 years after infection with SARS-CoV-2. This study may provide clues to why a subset of COVID-19 patients present with late thrombotic complications even after apparent recovery from SARS-CoV-2 infection. Thus, this project has a strong scientific rationale with direct clinical implications, especially given the emergence of SARS-CoV-2 variants such as delta and omicron that may prolong the pandemic and/or cause surges of COVID-19 in the coming months.

The purpose of this study was to observe real-world disease progression in mild-moderate COVID-19 patients with at least one risk factor for serve COVID-19 illness or death.

A phase II, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of DXP604 in patients with mild to moderate COVID-19. By determination of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) virus in nasopharyngeal swab samples by reverse transcription quantitative polymerase chain reaction (RT-qPCR) from baseline (2 h ± 30 min before dosing) to Viral load changes on day 8,to evaluate the efficacy of DXP604 monotherapy in patients with mild to moderate coronavirus disease 2019 (COVID-19). It was assumed that the difference in viral load change of SARS-CoV-2 virus from baseline (2 h ± 30 min before administration) to day 8 in nasopharyngeal swab samples by RT-qPCR between the experimental drug group and the placebo group was -1.00 log10 copies/mL.The null and alternative hypotheses comparing the experimental drug group with the placebo group are set as follows: H0：µ1 = µ2 H1：µ1 ≠ µ2

A Phase II Randomized, Open-label, Multicenter, Dose-ranging Study in Adults and Pediatric Individuals ≥ 12 years of Age to Assess the Safety, Immunogenicity, Pharmacokinetics, and Pharmacodynamics of AZD7442, a Combination Product of Two Monoclonal Antibodies (Tixagevimab and Cilgavimab), for Pre-exposure Prophylaxis of COVID-19

This is a Randomized, double-blind, Placebo-Controlled, Phase II Clinical Study to evaluate SSD8432 in combination with Ritonavir in asymptomatic infections or mild/common safety study of efficacy and safety in adult subjects with COVID-19.

The purpose of this double-blind, randomized, controlled study is to assess safety, reactogenicity, and immunogenicity of ZR-202-CoV, administered as 2 injections (i.m) at 28 days apart in adult subjects 60 years of age and above.

The United Arab Emirates (UAE), the Kingdom of Bahrain, Kuwait, Oman, and Qatar have authorised sotrovimab for emergency use. Local experience among physicians include recent successful COVID-19 vaccine pivotal studies supported by the authorities' willingness to expedite understanding of the role of monoclonal antibodies such as sotrovimab in the management of COVID-19 and expertise to integrate the latest knowledge into the local or regional COVID-19 management guidelines. The aim of this study is to collect local clinical evidence for sotrovimab effect in the real-life setting in the UAE and the Kingdom of Bahrain. Overall study population is 20,000 and the duration of the study will be approximately six months from recruitment date.

phase I study will evaluate the safety and tolerability of GEN2-Recombinant COVID-19 Vaccine (CHO cells) in healthy people aged 18 years and older. A total of 234 subjects were enrolled, of which 126 were enrolled in the 18-59-year-old group, and were randomly assigned to receive experimental vaccine 1, experimental vaccine 2, experimental vaccine 3 and placebo in a ratio of 2:2:2:1; 60- A total of 54 people were enrolled in the 69-year-old and ≥70-year-old groups, and were randomly assigned to receive the experimental vaccine 1 and placebo according to the ratio of 2:1.
