NCT ID: NCT05373030 Recruiting - Clinical trials for Immunogenicity and Safety of a Recombinant Adenovirus Type-5-vectored COVID-19 Vaccine Using for Sequential Immunization

Sequential Immunization With Recombinant Adenovirus Type-5-vectored COVID-19 Vaccine in Health Adults Based on 3 Doses Inactivated COVID-19 Vaccine

Start date: May 14, 2022
Phase: Phase 4
Study type: Interventional

COVID-19 is a novel coronavirus infection caused by respiratory droplets and contact transmission. With the spread of the epidemic, it has become a serious threat to global public health. China has launched a full range of vaccination including the third dose of homologous and sequential booster immunization. To further improve COVID-19 vaccine immunization strategy, we start the clinic research about sequential Immunization With Recombinant Adenovirus Type-5-vectored COVID-19 Vaccine in Health Adults Based on 3 Doses Inactivated COVID-19 Vaccine in Zhejiang province.

Study to Evaluate the Efficacy of IN STI-9199 in Treating Symptomatic COVID-19 in Outpatient Adults and Adolescents

Start date: April 2023
Phase: Phase 2
Study type: Interventional

This is a Phase 2 global, randomized, double-blind, placebo-controlled study designed to investigate the safety and preliminary efficacy of intranasal STI-9199 in adults and adolescents who are COVID-19 positive with mild to moderate symptoms.

NCT ID: NCT05372588 Completed - COVID-19 Clinical Trials

Phase 3 Boosting Study for the SARS-CoV-2 rS Variant Vaccines

COVID-19
Start date: May 25, 2022
Phase: Phase 3
Study type: Interventional

This is a Multi-Part, Phase 3, randomized, observer-blinded study to evaluate the safety and immunogenicity of booster doses of Omicron subvariant severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) recombinant (r) spike (S) protein nanoparticle vaccines (SARS-CoV-2 rS) adjuvanted with Matrix-M™ adjuvant (NVX-CoV2515 [BA.1] and NVX-CoV2540 [BA.5]) and bivalent (NVX-CoV2373 [prototype] + Omicron subvariant) SARS-CoV-2 rS vaccines (NVX-CoV2373 + NVX CoV2515 and NVX CoV2373 + NVX CoV2540) in previously vaccinated adults 18 years of age and older.

NCT ID: NCT05372341 Completed - Clinical trials for Long-term Consequences of COVID-19 Infection

Postoperative Outcomes of Covid-19 Patients Who Were Hospitalized in a Training and Research Hospital, Who Were Operated on Electively

Start date: May 15, 2022
Phase:
Study type: Observational

The Covid-19 infection has led to global health crisis. As the number of patients recovering from Covid-19 infection increases, it is necessary to create an understanding of the health problems that concern them. Reports of persistent and long-lasting effects are increasing after Covid-19 infection .

NCT ID: NCT05371925 Recruiting - Clinical trials for Endothelial Dysfunction

Endothelial Protection in Post COVID-19 Patients With Sulodexide

Start date: July 26, 2022
Phase: Phase 3
Study type: Interventional

This is a Prospective, multicenter, randomized (1:1, placebo use) trial with a parallel-group design to assess if the use of sulodexide influences serum levels of biomarkers for endothelial dysfunction on convalescent COVID-19 patients who suffered a moderate (or more severe) clinical presentation and have chronic comorbidities of high risk for endothelial dysfunction. The recruitment period is estimated at 6 months. The follow-up period of all participants will be 8 weeks. The participant will receive according to group allocation after randomization 1. study group: sulodexide oral dose of 250LRU capsule bid for 8 weeks. 2. control group: placebo oral dose of 1 capsule bid for 8 weeks. Participants in both groups will continue the standard of care recommended by national healthcare guidelines for each Country, including any concomitant medication indicated by their primary physician.

NCT ID: NCT05371561 Completed - COVID-19 Clinical Trials

Effect of PPE on Children's Fear in Dental Office

Start date: April 1, 2022
Phase: N/A
Study type: Interventional

the aim of the current study is to compare the effect of conventional facial PPE as 1)goggles + surgical masks, and 2)face shields + surgical masks versus 3)half-face and 4)full-face reusable respirators; on preoperative child's fear in the dental office.

NCT ID: NCT05371522 Enrolling by invitation - COVID-19 Clinical Trials

Neuro-inflammation and Post-infectious Fatigue in Individuals With and Without COVID-19

COVFATI
Start date: February 3, 2022
Phase: Phase 2/Phase 3
Study type: Interventional

Neuroinflammation can be an important regulator of long COVID, specifically fatigue and cognitive complaints. There is evidence that peripheral inflammation and neuro-inflammation are involved in fatigue and cognitive complaints, but precise pathophysiological mechanisms and causal relationship with viral infections are still unknown. The primary aim of this study is to quantify neuroinflammation with [18F]DPA-714 (TSPO-binding) PET scans in post-COVID-19 patients with and without post-infectious fatigue and cognitive complaints and relate it to cognitive, psychiatric and post-infectious fatigue symptoms.

NCT ID: NCT05371288 Not yet recruiting - COVID-19 Clinical Trials

The Role of Glutathione Deficiency and MSIDS Variables in Long COVID-19

Start date: June 2024
Phase: Early Phase 1
Study type: Interventional

The purpose of this research study is to assess if glutathione, along with NAC (N-acetyl cysteine) and Alpha lipoic acid (ALA), can help reverse some of the COVID long-haul symptoms.Subjects will be randomized in to one of two groups. Depending on the group they are randomized in to, subjects will be taking either a combination of NAC, Alamax CR, and liposomal GSH or the same three nutritional supplements with a multivitamin and magnesium. Regardless of the group, subjects will be asked questions to assess their COVID symptoms, physical and mental health status. They will also be asked to take blood samples.

NCT ID: NCT05371275 Withdrawn - COVID-19 Clinical Trials
