Filter by: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.
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.
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.
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 .
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.
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.
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.
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.
This is a one-site, interventional, prospective, single-arm, open-label, controlled phase-IIa trial evaluating the safety and efficacy of palbociclib in hospitalized, moderate COVID- 19 cases.
This is a phase 1/2 open-label study assessing the safety, reactogenicity, and immunogenicity of saRNA COVID-19 boost vaccines in participants that have been previously vaccinated against or previously infected with COVID-19.
