NCT ID: NCT05713279 Active, not recruiting - COVID-19 Clinical Trials

Study of Flonoltinib Maleate Tablets in the Treatment of Severe Novel Coronavirus (COVID-19) Infection

Start date: January 19, 2023
Phase: N/A
Study type: Interventional

Flonoltinib Maleate as a JAK/FLT3 dual target inhibitor, previous pharmacological experiments showed that the IC50 inhibition of JAK2 kinase was as low as 0.8 nM, while the IC50 inhibition of JAK1, JAK3 and TYK2 kinases was 26 nM, 39 nM and 2 nM, respectively, and the IC50 of FLT3 kinase was 15 nM. It has high inhibitory activity for JAK2 kinase and good selectivity for JAK family.Multiple pharmacodynamic models evaluating the anti-inflammatory effect of Flonoltinib Maleate showed that Flonoltinib Maleate showed better therapeutic effect than the clinical drug Ruxolitinib with lower toxicity.

NCT ID: NCT05713266 Active, not recruiting - COVID-19 Clinical Trials

Using Data From a Multisensor Rapid Health Assessment Device to Predict Decompensation in Long COVID (AIDI)

AIDI
Start date: October 31, 2022
Phase:
Study type: Observational

We are conducting a research study at the VA hospital in Bedford, MA to learn more about how a multisensor rapid health assessment device, MouthLab, can help predict or anticipate future health complications in patients with underline conditions after contracting COVID-19. The device was created by a health technology and digital medicine company called Aidar Health, Inc. MouthLab is a non-invasive, hand-held device that works like a breathalyzer. An individual breathes into the device for 60 seconds and the MouthLab gathers more than 10 vital health parameters like temperature, heart rate, SpO2, ECG, and basic lung functions. Participation in the study will last for 6 months, and the purpose is to gather health information from people who have been previously hospitalized with COVID-19. We will use the data to develop an algorithm that predicts future complications of COVID-19, especially among patients with complex conditions (i.e., heart failure, chronic kidney disease, diabetes, hypertension, asthma, chronic obstructive pulmonary disease), and enables early intervention.

NCT ID: NCT05711836 Completed - COVID-19 Clinical Trials

Role of HLA Genes and Innate Immunity in the Phenotypic Variability of COVID-19

3490
Start date: January 14, 2021
Phase:
Study type: Observational

Case-control, prospective retrospective association study of patients infected with SARS-CoV2 and cured by COVID19. Recruited patients were divided into two cohorts (cases: patients with respiratory failure that required hospitalization and ventilatory assistance. Controls: patients who had oligo-asymptomatic forms of COVID19). Patients' blood samples were collected on bibula paper, from which genomic DNA was extracted. Next-generation sequencing of HLA and innate immunity genes was performed on these samples. Genetic risk and protective variants were identified, based on the distribution of allele frequencies in the two cohorts. The aim of the study is to evaluate the role of genes of the HLA system and innate immunity in modulating the host response to SARS-CoV2 infection. The identification of these factors is essential from the perspective of public health (identifying individuals most in need of protection from infection as they are at higher risk of severe forms), basic research (characterization of molecular mechanisms of disease) and therapeutics (through knowledge of basic mechanisms, identify potential therapeutic targets and optimize the protective efficacy of vaccines).

NCT ID: NCT05710783 Completed - Clinical trials for SARS-CoV-2 Infection

Phase II/III Study of the AVX/COVID-12 Vaccine Against COVID-19 Applied as a Booster.

Start date: November 9, 2022
Phase: Phase 2/Phase 3
Study type: Interventional

This is a phase II/III parallel, double-blind, active-controlled, non-inferiority study to evaluate immunogenicity and safety of a booster immunization scheme of a single intramuscular dose of the recombinant vaccine against SARS-CoV-2 (AVX/COVID-12 vaccine) based on live recombinant Newcastle disease virus (rNDV) vector in healthy adults with a history of vaccination against COVID-19. The study is divided into two phases with immuno-bridging and 3000 healthy subjects showing evidence of prior immunity to SARS-CoV-2 are estimated to enrol. To verify non-inferiority in a determined number of subjects an intramuscular dose of the COVID-19 vaccine (ChAdOx-1-S[recombinant]) shall be used as active control in originally randomised subjects. The study shall be carried out in several sites of clinical research in Mexico.

NCT ID: NCT05709262 Completed - Hypoxia Clinical Trials

Comparison of Different Walk and Performance Test in Detecting Silent Hypoxia

Start date: December 19, 2021
Phase:
Study type: Observational [Patient Registry]

Healthcare systems around the world have been dealing with COVID 19. One of the main manifestations of this infection is lung involvement of varying degrees, causing a spectrum of diseases from mild lower respiratory tract infection to severe Adult Respiratory Distress Syndrome (ARDS). One of the important clinical parameters is to detect hypoxia early in order to initiate a higher level of care at the earliest. The presence of silent or latent hypoxia has made this task difficult in COVID 19. Besides, critical findings such as silent hypoxia that is not at rest but triggered by effort can be revealed by some practical field tests such as the 6-minute walk test or the 1-minute chair sit and stand test. Moreover, these simple tools also help to investigate the patient's readiness for discharge. In this way, it will be useful to evaluate their usability in discharge decisions or in determining the post-discharge cardiopulmonary reserves of the patients and therefore their rehabilitation needs. Although walk and performance tests can be performed naturally, safely and simply, more similarly to movements in daily living activities compared to cardiopulmonary exercise tests, the interest in these tests has increased over the years, especially in subjects such as exercise capacity, mortality and morbidity expectation, or oxygen desaturation in patients with chronic cardiopulmonary pathology. The number of studies in 19 patients is quite limited. For this reason, the necessity of new studies on different field tests to detect the presence of latent hypoxia, which expresses the oxygen desaturation triggered by effort, and to evaluate the exercise tolerance status before discharge, has been emphasized in recent reviews.The aim of this study is to determine the presence of silent hypoxia, which expresses the oxygen desaturation triggered by effort, in Covid-19 patients and to compare the different short-term walk and performance tests, which the investigators consider easier and applicable in the conditions of the pandemic environment, with the classical gold standard test ( Six minute walk test) in order to evaluate the exercise tolerance status of the patients before discharge.

NCT ID: NCT05706467 Not yet recruiting - COVID-19 Pneumonia Clinical Trials

The Difference Between Non-invasive High-frequency Oscillatory Ventilation and Non-invasive Continuous Airway Pressure Ventilation in COVID-19 With Acute Hypoxemia

Start date: February 10, 2023
Phase: N/A
Study type: Interventional

High frequency oscillatory ventilation (HFOV), as an ideal lung protection ventilation method, has been gradually applied to neonatal intensive care treatment, and is currently recommended as a rescue method for neonatal acute respiratory distress syndrome (ARDS) after failure of conventional mechanical ventilation. Although its ability to improve oxygenation and enhance carbon dioxide (CO2) clearance has been repeatedly demonstrated in laboratory studies, its impact on the clinical results of these patients is still uncertain. Noninvasive high-frequency oscillatory ventilation (nHFOV) combines the advantages of HFOV and non-invasive ventilation, and has become the current research focus in this field. It is recommended to use it after the failure of routine non-invasive ventilation treatment to avoid intubation. For the treatment of intubation, there is still a lack of large-scale clinical trials to systematically explore its efficacy. The gradual increase of clinical application of nHFOV has also enriched its application in the treatment of other diseases. At present, non-invasive high-frequency oscillatory ventilation has not been applied to the study of adult COVID-19 with acute hypoxemia, which will be the first study in this field.
