Filter by:The goal of this clinical trial (phase 2/phase 3) is to evaluate the efficacy and safety of emetine administered orally for symptomatic Covid-19 patients in patients ages 30 years and above. Participants will be asked to: - Take Emetine 6mg orally for 10 consecutive days - Be monitored by healthcare staff or self-monitor for daily vital signs and symptoms - Undergo blood draws Researchers will compare the control group given placebo medicine to assess if emetine improved the symptoms of Covid-19.
The goal of this study is to test the reliability (with a test-retest process) of 30 seconds Sit to Stand and Timed Up and Go in an adult population with long-covid, hospitalised in a rehabilitation center.
Adults who do not have major health, kidney, gastrointestinal disease will be randomized to receive oral mitoquinone/mitoquinol mesylate (Mito-MES) versus placebo to prevent the development and progression of COVID-19 after high-risk exposure to a person with confirmed SARS-CoV-2 infection.
This is an open-label, randomized, parallel-controlled clinical trial conducted in people aged 18 years and older to evaluate the immunogenicity and safety of two SARS-CoV-2 bivalent vaccines constructed by adenovirus type 5-based or mRNA-based technics.
The purpose of the study is to learn about the safety of PF-07817883 and how PF-07817883 is processed in the body of adult participants. These participants will have different degrees of loss of liver function. Participants with mild, moderate, severe or no loss of liver function will be enrolled in 4 groups. This study is seeking participants who: - are male or female of 18- 75 years of age - either have different amounts of damage to liver function or for one of the groups, no damage - willing to follow the requirements of the study including stay at clinic for 6 nights and 7 days About, 6-8 participants will be selected in groups 1, 2 and 3. In group 4, around 4 to 8 participants will be selected. If participants consent to participate in the study, it may take up to 4 weeks to complete all the tests to confirm if they are eligible to participate in the study. If they seem to be eligible for the study, participants will be admitted to a clinic research unit (CRU) atleast 12 hours before dosing. On Day 1, participants will receive a single dose of study medicine (Day 1). A series of blood samples will be collected before and after dosing. Participants will be discharged from the CRU on Day 6. A follow-up phone call (on CRU visit, if needed), will occur 28-35 days after dosing. The whole study will last for a minimum of 5 weeks and a maximum of 10 weeks.
The current standard of care for diagnostic of SARS-CoV-2 infection involves sample collection which is then prepared and measured via real time-polymerase chain reaction (RT-PCR). This process is time consuming and dependent on expensive instrumentation and trained technicians to perform both the sample preparation and assay. In many cases, sample turn-around times can take hours to several days. There are no established monitoring nationwide protocols for COVID-19 prevention of infection. Due to the lack of such protocols, this study will provide the proper experience to design a safe monitoring schema of asymptomatic cases of COVID-19. Self-testing using currently available RDT has a high specificity and relatively high sensitivity to identify individuals with a high probability of contagiousness. Therefore, we intend to use these RDT (Rapid diagnostic tests) for other use. There are several studies that point to the importance of the use of RDTs to monitor COVID-19 (3). The recent metadata indicate that the performance of the antigen test is crucial for obtaining good results to detect positive cases. We have already validated in the laboratory and using relevant clinical samples several different labels of antigen tests and we have compared them with already approved USA FDA antigen tests to confirm their performance prior to using them in this study. This project aims to monitor once a week the presence of SARS CoV-2 antigens using anterior nares (AN) swab self-process, executing the test and recording of the result, immediately after. The lack of affordable diagnostic tests which can detect the presence of SARS-CoV-2 in the general population which can give near real-time results is one critical missing control intervention in USA for the control of the pandemic and the spread of this disease. As public health restrictions begin to ease and people return to normal activities, while the COVID-19 pandemic is still a threat, a rapid diagnostic assay that does not require the sophisticated laboratory equipment and techniques could provide a significant advantage to screen asymptomatic individuals. The routine use of such rapid tests is a key element to show efficacy of protocol. We adjusted to once a week testing based on the medium to low risk of the elderly population of this study. The list of rapid nucleoprotein tests utilized in the current study are: NETO Corona test, Novir INSTA-TM COVID-19 Rapid Antigen test, COVICHEK COVID-19 Ag Test, SpectraBiotech COVID-19 track antigen test, Blandford Biotech AS-15™ Rapid Antigen Detection Kit SARS-CoV-2 Test (Colloidal Gold Method), Abbott BinaxNow tests. BACKGROUND The SARS-CoV-2 Direct Antigen Rapid Test ("Lateral flow") is an immunoassay developed for the qualitative detection of SARS-CoV-2 viral particles/secreted protein in anterior nasal swabs and/or saliva samples from both asymptomatic and suspected participants with COVID-19 infection. Lateral flow strips are printed with a monoclonal antibody that binds the signature SARS-CoV-2 viral particles/protein (Test line) and a control antibody (Control line) for quality control. A second monoclonal antibody is attached to gold nanoparticles (conjugate) and quencher buffer, and mixed with the nasal sample. The SARS-CoV-2 nucleocapsid protein attach to both antibodies resulting in a visual line on the test strip within 15 minutes. Prior experience in the detection of virus and viral proteins via antibody binding using lateral flow have been done through IDx20, Inc. The Housing Authority and the Public Health Department of the City of Chelsea will be overseeing this study.
Optimal approach for adult patients hospitalized with severe and critical COVID-19 non-responsive to antiviral and immunomodulatory drugs is not well established. The study aim is to evaluate feasibility and safety of extracorporeal photopheresis (ECP) in this setting.
The goal of this single center, double-blinded, placebo-controlled, and randomized Phase 1 trial is to determine if i.v. citicoline is safe and efficacious compared to i.v. saline/control in adults presenting with SARS CoV-2 infection complicated by acute hypoxemic respiratory failure. The main questions it aims to answer: - Is citicoline safe in this patient population? - Does citicoline have a benefit in terms of improving oxygenation? - Does citicoline reduce overall severity of illness as reflected by standardized scales. Patients will be assigned to i.v. treatment with citicoline or saline twice daily for 5 consecutive days. SpO2/FiO2 ratios will be recorded daily as per standard clinical practice to compare citicoline treatments at three different doses to placebo.
The research in this VA Merit will examine the effects of obesity and Post-COVID Conditions (PCC) on physical functioning, health-related quality of life, and adipose tissue inflammatory and cellular senescence profiles in older Veterans. Further, it will evaluate whether a weight loss intervention, including dietary modification and exercise, in obese Veterans with and without PCC will reduce systemic and adipose tissue inflammation and senescence and promote PCC recovery.
This study aims to use vaccination information from state vaccine registries linked with HealthVerity insurance claims for the following: - to measure how effective the Pfizer-BioNTech vaccine is at preventing post-COVID conditions. - to understand characteristics of patients who are receiving COVID-19 vaccines. All patients whose information is kept unidentified in the HealthVerity database are eligible to be included for both aims of this study.
