Filter by:This is an observational cohort study to evaluate real-world vaccine effectiveness and durability of Moderna COVID-19 vaccine among a diverse population at Kaiser Permanente Southern California (KPSC). The primary objective of this study is to evaluate the vaccine effectiveness (VE) of receipt of Moderna COVID-19 vaccine in preventing SARS-CoV-2 infection and severe COVID-19 disease. SARS-CoV-2 infection will be defined as a positive antigen test result as well as a positive molecular diagnostic test among symptomatic or asymptomatic participants or a COVID-19 diagnosis code. Severe COVID-19 disease will be defined as COVID-19 hospitalization or mortality.
Due to the COVID-19 pandemic, the world has seen the need to identify groups of patients who experience various effects in the medium and long term after recovering from the initial illness. These medium- and long-term effects are collectively known as the post-COVID-19 condition, Long-COVID, or prolonged COVID. Current evidence indicates, with conservative estimates, that between 10% and 20% of the population could be affected. Its nature is varied and ranges from physical conditions such as chronic fatigue, dyspnea and muscle weakness, to neurocognitive (compromised memory, decreased concentration) and psychological (anxiety, depression, anguish, stress). Early recognition and treatment of this symptom burden is essential for physical recovery and mental health. Due to its multivariate nature, it has been suggested that optimal recovery of patients' quality of life would only be achieved to the extent that their main symptoms are addressed from an interdisciplinary perspective.
To evaluate the safety, humoral immunogenicity, cellular immunogenicity and immune persistence following a heterologous booster dose of recombinant SARS-CoV-2 trivalent vaccine (CHO Cell) LYB002 in Chinese adults 18 years and above completed three-dose Inactivated COVID-19 vaccine;
The goal of this clinical trial is to assess the immunogenicity and safety following a heterologous booster dose of recombinant SARS-CoV-2 vaccine (CHO cell) LYB001 in adults 18-59 years of age completed two- or three-dose inactivated COVID-19 vaccine. The main questions it aims to answer are: - whether LYB001 group is better on immunogenicity than the control group of inactivated vaccine? - whether LYB001 group has better performance on safety than the control group of inactivated vaccine, such as the lower adverse reaction rate?
This is a Phase 2/3, randomized, double-blind study to evaluate the safety and immunogenicity of different booster dose levels of the monovalent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) recombinant (r) spike (S) protein nanoparticle (SARS-CoV-2 rS) vaccines with Matrix-M™ adjuvant (NVX-CoV2373 [prototype Wuhan vaccine with Matrix-M adjuvant] or NVX-CoV2601 [Omicron XBB.1.5 subvariant vaccine with Matrix-M adjuvant]).
This study is an interventional, randomized, multinational, multicenter, double-blind, phase 2 study with a follow-up period of circa 12 months. The intension of this clinical trial is to investigate the long-term sequelae (named Long COVID syndrome; post COVID or PASC) of an infection with Corona Virus Type 2 that has resulted in a condition known as Severe Acute Respiratory Syndrome Corona Virus Type 2 (SARS-CoV-2). The purpose of this study is to evaluate the efficacy and safety of BC 007 as a treatment for long-lasting COVID-symptoms in patients who were neither intubated nor supported with extracorporeal blood oxygenation (ECMO) during their acute COVID-19 infection. The study drug acts by neutralizing functional autoantibodies directed against G-protein coupled receptors (GPCRs). Neutralization of the autoantibodies is expected to induce a beneficial effect on symptoms typically seen in patients with long COVID syndrome. Functional autoantibodies are proteins belonging to the class of G-type immunoglobulins that can be synthesized by activation of the immune system and can induce various pathogenic activities by binding to one of the extracellular loops of G-proteins (GPCR-AAB). The study consists of a screening phase of up to 35 days, treatment (two administrations by intravenous infusion at two-week intervals either with the study drug (BC 007) or with placebo (NaCl 0.9%), with an initial follow-up period of 15 days after each administration and an extended follow-up period of 330 days. Patients are required to visit the study center for follow-up visits at specified intervals. For the entire study duration of 395 days from screening to the end of the study, 11 site visits are planned.
This is an open-labeled, no placebo, Phase IIa clinical trial. The purpose of this study is to evaluate the immunogenicity and safety of one booster vaccine dose of SARS-CoV-2 DNA Vaccine (ICCOV) in adults aged 18 to 75 years who have received two to four dosese of COVID-19 vaccine.
Justification: among the sequelae of Covid-19 in clinical practice we frequently find persistent neuromusculoskeletal pain. Previous studies carried out by this research group and in the scientific literature have shown that "Pain Neuroscience Education" (PNE) and Therapeutic Exercise (TE) constitute an effective care strategy in the treatment of persistent pain. Therefore, with this research we will try to respond with a treatment proposal from Primary Care (PC). Objective: to determine whether an PNE and TE program is effective in patients presenting Long Covid Pain (LCP). Method: Randomized clinical trial. A sample of 80 subjects will be recruited. The intervention group will receive a program of TE and PNE, of 12 weeks duration: 5 weeks of PNE, of 1 weekly session of 90 minutes, and 7 weeks of TE, with a total of 19 sessions of 60 minutes duration. The control group will receive the usual treatment. An assessment will be made at the beginning and after the end of the intervention, where the following variables will be measured: quality of life, intensity, distribution and expansion of pain, healthy physical condition and blood test values. These will be evaluated by means of physical examination, questionnaires and laboratory tests. Applicability of the expected results: The proposed intervention is simple and reproducible. It requires few resources, and can produce changes in pain perception, functionality and quality of life in patients with LCP.
There is an increased lack of short- and long-term real-life effectiveness and safety data on new oral antivirals authorised and commercialised to treat COVID-19. To date, only two clinical trials have been published with data on the efficacy and safety of the use of the Paxlovid® and Lagevrio®. Since there is a public health, political, social and economic pressure to prevent severity, hospitalisation and death from COVID-19, monitoring the effectiveness and safety of commercialised oral antiviral therapies against COVID-19 has become emergent pharmacovigilance and public health task. The objective of the study is to monitor the post-marketing safety and effectiveness of the new oral antivirals indicated for the treatment of COVID-19, namely Nirmatrelvir/Ritonavir (Paxlovid®) and Molnupiravir (Lagevrio®), having as holders of the Authorization of Market introduction to Pfizer Europe MA EEIG and Merck Sharp & Dohme B.V., respectively.
The aim of this study is to find out the role of Covid-19 in salivary gland infection and its recurrence.
