Active clinical trials for "COVID-19"

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.

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.

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.

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.

Randomized, double-blind, multicenter parallel-group clinical study of safety, tolerability and immunogenicity of the Betuvax-CoV-2 vaccine. The aim of this study is to investigate the safety, tolerability and immunogenicity of the Betuvax-CoV-2 Recombinant vaccine for the prevention of coronavirus infection caused by the SARS-CoV-2 virus, suspension for intramuscular administration, 10 μg/ml and 40 μg/ml (Ltd. Institute of New Medical Technologies, Russia) in healthy adult volunteers, aged 18 to 60 (inclusive).

The newly recognised disease COVID-19 is caused by the Severe-Acute-Respiratory-Syndrome Coronavirus 2 (SARS-CoV-2), which rapidly spread globally in late 2019, reaching pandemic proportions. The clinical spectrum of SARS-CoV-2 infection is broad, encompassing asymptomatic infection, mild upper respiratory tract illness and mild extrapulmonary symptoms, and severe viral pneumonia with respiratory failure and even death. For COVID-19, most primary care physicians have initially treated their patients at home according to their judgment, with various treatment regimens they believe are most appropriate based on their experience/expertise. We recently published a note on how we were treating patients at home based on the pathophysiology underlining the mild/moderate symptoms at the onset of the illness and the proposal of simple drugs that theoretically better fit these mechanisms. Because the common early mild symptoms of COVID-19 highlight a systemic inflammatory process, there is the recommendation of using anti-inflammatory agents to limit excessive host inflammatory responses to the viral infection, including non-steroidal anti-inflammatory drugs and corticosteroids. Moreover, COVID-19 patients are exposed to the risk of thromboembolic events and anticoagulant prophylaxis is recommended even at home, in particular settings, unless contraindicated. In an academic matched-cohort study, we found that early treatment of COVID-19 patients at home by their family doctors according to the proposed recommendation regimen almost completely prevented the need for hospital admission (the most clinically relevant outcome of the study along with death) due to progression toward more severe illness (2 out of 90 patients), compared to patients in the 'control' cohort who were treated at home according to their family physician's assessments (13 out of 90 patients). However, the rate of hospitalization was a secondary outcome of the study and the possibility of a casual finding cannot be definitely excluded. Moreover, these findings were achieved in a retrospective observational study with two matched cohorts of COVID-19 patients, a possible additional limitation of the robustness of the conclusions that would deserve further validation. Thus, we have considered the observed reduction in patient hospitalization a hypothesis generating finding to be confirmed. In this pragmatic, prospective, three-months, cluster randomized, open-label, blinded endpoint (PROBE) clinical trial, we will compare two groups of family doctors according to a randomized approach, who will treat their COVID19-patients with the proposed recommendation algorithm or other treatment regimens they normally feel appropriate according to their usual clinical practice, and monitor them longitudinally up to 3 months. Our working hypothesis is that following the proposed recommendation algorithm the early COVID-19-related inflammatory process is limited, preventing the need of hospital admission at larger extent than with other therapeutic approaches also targeting early symptoms of the illness at home. Should the findings be confirmed, the tested standardized treatment protocol would achieve major benefits for patients with early COVID-19 in particular in relation to a remarkably reduced risk of hospitalization that is expected to translate into reduced morbility and, possibly, mortality. Notably, these expected clinical benefits would be associated with remarkably reduced treatment costs related to reduced hospitalization.

This study will compare two approaches to cognitive rehabilitation in adults with long COVID with persistent, mild to moderate, cognitive impairment. Both approaches will feature a web-based computer "game" that trains cognitive processing speed, i.e., how quickly individuals process information that they receive through their senses. This training is termed Speed of Processing Training (SOPT). One approach will add (A) in-lab training on everyday activities with important cognitive components and (B) procedures designed to transfer improvements in cognition from the treatment setting to everyday life. Component A will include work-related tasks. This approach is termed Constraint-Induced Cognitive Therapy (CICT). The other approach will add (A) in-lab training on relaxation, healthy nutrition, and healthy sleep and (B) procedures designed to promote integration of these lifestyle changes into everyday life. This approach is termed Brain Fitness Training (BFT). A subset of participants, who qualify for and and desire vocational rehabilitation (VR), will receive VR from the Alabama Department of Rehabilitation Services (ADRS) in addition to CICT or BFT. ADRS VR will include career counseling, prescription of on-the-job accommodations, and guidance on return-to-work. Those in the CICT + VR group will also receive on-the-job coaching from a peer mentor for a month after completing training. CICT, with or without VR, will involve 30 hours of training. Ten 3-hour in-lab, face-to-face, therapist-directed sessions will be scheduled. These sessions will feature one hour of SOPT; the remainder will be committed to in-lab training on the target behaviors and the procedures designed to promote transfer of therapeutic gains to daily life and improving skills essential to work; the set of the latter procedures is termed the Transfer Package. To accommodate the demands of participants' other activities, training sessions will be permitted to be scheduled as tightly as every weekday over 2 weeks or as loosely as every other weekday or so over 4 weeks. If a family caregiver is available, they will receive training on how to best support participants in their therapeutic program. After training ends, four follow-up phone calls will be scheduled approximately one-week apart with participants to promote integration of the skills gained during training into everyday life. BFT, with or without VR, will involve 30 hours of training following the same schedule as for CICT. Ten 3-hour in-lab, face-to-face, therapist-directed sessions will be scheduled. These sessions will feature one hour of SOPT; the remainder will be committed to in-lab training on the target behaviors (healthy sleep, nutrition and relaxation habits) and the procedures designed to promote transfer of behavior change to daily life. If a family caregiver is available, they will receive training on how to best support participants in their therapeutic program. After training ends, four follow-up phone calls will be scheduled approximately one-week apart with participants to promote integration of the skills gained during training into everyday life. Participants will be randomly assigned to the interventions. Randomization will be stratified by whether participants qualify for and desire VR from ADRS or not. If yes, participants will be randomized in equal numbers to CICT + VR or BFT + VR. If no, participants will be randomized in equal numbers to CICT or BFT. Testing will happen one month before treatment, one day before treatment, one day afterwards, and 6- and 12-months afterwards. Outcomes measured will include cognitive processing speed, cognitive function on laboratory tests, and spontaneous performance of everyday activities with important cognitive components in daily life. Another important outcome measure will be whether or not participants were able to return back to work or had significant improvements in their work activities.

This study adopts a randomized, double-blind, placebo parallel control design, and is expected to include 168 eligible patients with severe novel coronavirus pneumonia.

One way to empower a community, in epidemic control issues, is to know the first-hand screening tools. There are no evaluations of these home-use tools from the perspective of patient and citizen empowerment and participation. The main objective of this study is to analyze whether a self-tracking and self-tracing tool, developed in a participatory way, increases the risk identification of the disease and the empowerment in terms of risk management of transmission by the participants.
