Filter by:This is a Phase I/II trial to evaluate the safety and efficacy of intravenous (IV) administration of bone marrow mesenchymal stem cell derived extracellular vesicles (EV), ExoFlo, as treatment for Post-Acute COVID-19 and Chronic Post-COVID-19 syndrome.
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) causing coronavirus disease, Covid-19, has spread rapidly across the globe since its emergence in January 2020. As of January 2021, there are 87.6 million confirmed cases worldwide, with 1.9milion deaths. In conjunction with this high disease incidence, there have also been reports of Covid-19 related sleep disordered breathing, with up 18% in a Chinese study and 57% in an Italian study of individuals with Covid-19 reporting sleep disturbance. Obstructive Sleep Apnea (OSA) is a common, chronic condition due to partial or complete upper airway collapse during sleep. OSA is more common in males & obese individuals, both of which are more adversely affected by SARS-CoV-2 infection. Furthermore, inflammation of the upper airway, or nasal passages leading to congestion could lead to a compromised upper airway during sleep and subsequently, obstructive sleep apnea. We believe that's SARS -CoV-2 infection, and subsequent Covid-19 will lead to an altered microbiome in the upper airway. This is turn will lead to worsening nasal inflammation and congestion, which could predispose individual with previous Covid-19 disease to OSA. Additionally, OSA is treated with Continuous Positive Airway Pressure (CPAP) a machine which delivers pressurized air into the upper airway via a face mask. This keeps the upper airway open during sleep. When CPAP is well tolerated by individuals, it works well to reduce the symptoms of OSA. Unfortunately, many patients find it difficult to tolerate CPAP. One reason often reported for poor tolerance is nasal congestion. We believe that an altered upper airway microbiome, due to previous SARS-CoV-2 infection, will affect treatment adherence to CPAP therapy. Secondly, we will investigate if treatment with CPAP therapy causes any change in the upper airway microbiome.
During the COVID-19 epidemic, the time spent by adults on the stomach has increased. Therefore, the likelihood of adverse changes in lifestyles has increased. In this study, the changes in nutritional habits, physical activities and body weights of adult individuals during the epidemic will be evaluated. A questionnaire including questions about nutritional habits, physical activity status and changes in body weights will be administered to individuals. The results will be evaluated with the appropriate statistical method. The survey will be administered once. The estimated time to reach the total number is 3 months.
Evaluation of immunogenicity, safety and persistence of the subjects with HIV infected received the third dose of inactivated COVID-19 vaccine .
To evaluate the post-marketing immunogenicity, safety and antibody persistence of the third dose (booster) of Covid-19 vaccine in patients aged 60 years or older with hypertension and/or diabetes.
To evaluate the post-marketing immunogenicity, safety and antibody persistence of the third dose (booster) of Covid-19 vaccine in patients aged 60 years or older with hypertension and/or diabetes.
Evaluation of immunogenicity, safety and persistence of the subjects aged 60 years and above with chronic bronchitis and chronic obstructive pulmonary disease received the third dose of inactivated COVID-19 vaccine .
To Study serum CRP, D-dimer and serum ferritin in adult patients with COVID-19 for the presence or absence of clinically validated definitions of mortality, severe COVID-19, ARDS, and intensive care unit (ICU) care.
A galectin antagonist prevents viral entry of Sars-CoV-2 virus by blocking the specific terminal on the surface receptors that enables the virus to enter human cells. This inhibitor - ProLectin M is a novel substance that is given orally to individuals who have an infection with Sars-CoV-2 or its subsequent mutations causing COVID19 disease. The oral tablet is chewed every hour, for 8 hours daily, for 7 days. We hypothesize that patients receiving the active investigational product (ProLectin M), irrespective of their vaccination status, or underlying medical conditions, will have a faster recovery from COVID19 compared to those receiving its matching placebo. The trial is approved by an Institutional Review Board for safety and all participants will need to provide written informed consent to participate in this trial. The safety of ProLectin M is established as the drug substance is recognised as a safe substance. However, its benefits in relieving patients from the COVID19 infection and providing the patients faster recovery from its clinical symptoms and prevention of delayed sequelae of the infection has not been proven yet.
