Filter by:This study is a randomized, double-blinded, and placebo controlled phase 1&2 clinical trial of the SARS-CoV-2 inactivated vaccine manufactured by Sinovac Research & Development Co., Ltd. The purpose of this study is to evaluate the safety and immunogenicity of the experimental vaccine in healthy children and adolescents aged 3-17 years
Patients with diabetes have been listed as people at higher risk for severe illness from COVID-19. Moreover, the relationship between diabetes-related phenotypes and the severity of COVID-19 remains unknown. This observational study aims to to evaluate the risk of disease severity and mortality in association with diabetes in COVID-19 inpatients and identify the clinical and biological features associated with worse outcomes.
Evaluate the safety pharmacokinetics and pharmacodynamics (PK/PD)of a single dose of Kamada anti-severe acute respiratory syndrome (SARS)- CoV-2 in patients hospitalized with COVID-19 caused pneumonia
Up to 1/3 of all patients infected with COVID-19 can develop complications that require hospitalization. Severe pneumonia associated with acute respiratory distress syndrome (ARDS) is the most threatening and feared complication of COVID-19 infection, with mortality rates close to 50% in some groups. Autopsies between these severe cases reveal severe capillary involvement, with signs of intense inflammatory changes, microvascular thrombosis, endothelial injury and abnormal tissue repair. The available evidence suggests that abnormal activation or imbalance in the counter-regulation of the kallikrein-kinin system may play a central role in a positive feedback cycle, leading to consequent diffuse microangiopathy. Blockade of the kallikrein-kinin system can therefore prevent deterioration of lung function by reducing inflammation, edema and microthrombosis. The objective of this phase IIb study is to assess the preliminary effects on the oxygenation parameters of an antisense oligonucleotide that inhibits pre-kallikrein synthesis in patients with moderate to severe COVID-19.
It is an established fact that, corona virus spread through the respiratory droplets. Colonization of the virus in oropharynx and/or nasopharynx is considered to be major factor for transmissibility of the virus through respiratory secretions. Preventing colonization of the virus by administrating povidone iodine in the nasal passage therefore, a rational thought which is supported by recent evidence of in-vitro virucidal action of povidone iodine in Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS CoV-2). Therefore, the study is designed to assess the virucidal effect of povidone iodine on COVID-19 virus in-vivo.This open label randomized clinical trial will be conducted at Department of Otorhinolaryngology and Head Neck Surgery, in collaboration with Department of Virology and Department of Medicine in Dhaka Medical College (DMC) Hospital. The study will be conducted from September 2020 to October 2020. Total 175 confirmed cases of COVID-19 disease, proven by Reverse transcription polymerase chain reaction (RT-PCR) testing will be enrolled in this study. Written informed consent will be ensured before participation. In case of no literacy, finger print will be considered for written permission.Consent will be sought from the legal guardian in case of minor or underaged.Formal ethical clearance will be taken from Ethical Review Committee (ERC) of Dhaka Medical College. All of the Participants will be divided into seven groups: Group A will receive Povidone iodine (PVP-I) nasal irrigation at concentration of 0.4%, Group B and Group C will received 0.5% and 0.6%; Group D will receive PVP-I nasal spray at concentration of 0.5% and Group E will received at 0.6% concentration. Group F (Placebo comparator group) will receive nasal irrigation by distilled water (DW) and Group G (Placebo comparator group) will received nasal spray by distilled water. The contact time will be minimum 30 seconds. After the individual application of PVP-I and distilled water in respective participant, they will be tested again for RT-PCR for COVID-19 from nasopharyngeal and oropharyngeal sample. All patients will be subjected to detail history, physical examination and adverse events. Block Randomization will be followed for randomization. Data will be recorded in a semi-structured questionnaire and will be analyzed by 'R-4.0.2' data analysis software
This current protocol encompasses an investigator-blinded randomized exercise intervention in 10 COVID-19 survivors that have been discharged from hospital. The subjects will be randomized to perform three different exercise training protocols in a random order. The aim is to clarify the feasibility and safety of three training protocols in COVID-19 survivors. The hypothesis is that patients surviving COVID-19 will be able to comply to all training protocols.
Solving the problem of detecting asymptomatic carriers who can transmit infection is key to protecting vulnerable residents of nursing homes and assisted living facilities, to protecting frontline workers who care for them, and to facilitating return to work (including return of nurses and medical assistants). The wearable biometric technology, if widely disseminated among vulnerable populations and the community-at-large, will help avoid the ravages of seasonal flu and other contagious illnesses, and the society will be better prepared for future waves of COVID-19 or other pandemics. Even if a vaccine is developed, due to immune senescence and immunocompromise, elderly people and those with chronic medical conditions may not be well protected by it. Continuous biomonitoring provides another layer of protection for them.
The goal of the study is to examine whether a shared decision making intervention improves decision making about colon cancer screening for patients who had their colonoscopy delayed or postponed due to the COVID pandemic. Eligible patients (n=800) will be randomly assigned to either the intervention or control arm. A subset will be surveyed about 6-8 weeks post intervention to measure shared decision making, their intention to follow through with screening, and their decisional conflict. Study staff will conduct medical chart review to track receipt of colon cancer screening within 6 months. The statistician will test whether patients in the intervention arm report more shared decision making, less decisional conflict, higher intention to follow through on screening and have higher screening rates compared to those in the control arm.
Plasma, the supernatant part of blood, contains a variety of different proteins, including immunoglobulins. These proteins, also called antibodies, are directed to previous foreign infecting organisms, such as virus, bacteria or parasites. Patients recovering from SARS-Cov-2 infection may develop protective antibodies which can prevent reinfection with the same agent or similar organisms with shared molecular structures. Those antibodies may be transferred to other patients through collection of such convalescent plasma from recovered donors and its transfusion to ill patients. In this research, the primary hypothesis is that those antibodies can exert passive immunization and help ameliorate symptoms from COVID-19 (Coronavirus Disease 2019), resulting in higher clinical improvement rates at day 28, especially when administered early in the infection course.
This study aims to determine if a strategy of recommending prone (on stomach) positioning of patients positive or suspected positive for coronavirus disease 2019 (COVID-19) requiring supplemental oxygen, but not mechanically ventilated, Is feasible in the inpatient setting. This study will be performed as a pragmatic pilot clinical trial to gain information relevant to the future conduct of a larger trial.
