Filter by:This Phase 1 trial is an open-label trial to evaluate the safety, reactogenicity and immunogenicity of two dosages (10^6 PFU and 10^7 PFU) of intranasal CVXGA1 administered as a single dose in healthy adults age 18-55 years and in adolescents age 12-17.
The primary goal of this project is to study the feasibility of a prototype brain-dedicated PET insert for an MR scanner for simultaneous acquisition of PET/MR images of metabolism and perfusion in Covid-19 negative and positive/once positive subjects. This study serves as a pilot study for establishing an imaging protocol for combined PET and MR derived functional information as well as MRI acquired anatomical information.
An observational, retrospective, classic cohort study of adult patients hospitalized for severe pneumonia with a diagnosis of SARS-CoV-2 by RT-PCR will be carried out. The cohort will be divided into two arms: a group of patients who received treatment with anti-SARS-CoV-2 hyperimmune serum and a group of patients not exposed to the intervention during hospitalization corresponding to the period prior to the approval of the anti-hyperimmune serum SARS-CoV-2 for use. All patients will be have structured follow-up at 14, 21 and 28 days, until discharge or death.
The purpose of this study is to determine the effects of the clinical course of treatment as well as long-term symptoms of COVID-19 on respiratory function, exercise capacity, and quality of life.
The purpose of this clinical study, CLO-SCB-2019-010, is to assess the immunogenicity, reactogenicity and safety of the SCB-2019 vaccine in Chinese participants, and to show the comparability of the immune response versus randomly selected individuals who participated in the large-scale efficacy study with the SCB-2019 vaccine (Study CLO-SCB-2019-003).
During the COVID-19 pandemic, health employees are at high risk of infection. This study aimed to determine experiences with an aerosol box (AB), used with the aim of preventing contamination by droplets during internal jugular vein cannulation which requires close contact with COVID-19 patients, and the necessity to use this device.
Double-blind, placebo-controlled study with open dose selection period for safety assessment, tolerance and immunogenicity of the drug "GamKOVID-Vac M, a combined vector vaccine for prevention of coronavirus infection caused by the virus SARS-CoV-2" in adolescents
Multi-centered, randomized, open label clinical trial to study the safety and effectivity of hydroxychloroquine + azithromycin to treat COVID-19 symptoms in primary care patients.
This study is a randomized, placebo-controlled and open design, phase 4 clinical trial of an inactivated COVID-19 vaccine (CoronaVac) manufactured by Sinovac Research and Development Co., Ltd. The purpose of this study is to evaluate the immunogenicity and safety of the CoronaVac in healthy population aged 18 years and older.
The purpose of this study is to provide new insights into the pathophysiology of emergency hematopoiesis detected in severe COVID-19 patients. The investigators aim to explore the ability of calprotectin to induce an immunosuppressive myeloid program at the hematopoietic stem and progenitor cell (HSPC) level, and to identify the receptor(s) involved in this effect. Since patients with a hematological malignancy demonstrate a very high propensity to develop a severe COVID-19, the investigators will explore how HSPCs collected from patients with a myeloid malignancy respond to calprotectin.
