Filter by:The purpose of the study is to assess seroprevalence of COVID-19 infection in a cohort of HIV + patients and in a cohort of patients taking PrEP by emtricitabine / tenofovir.
In this study we will be monitoring for patient events (emergency department admission, hospital admission, admission to an observation unit, or death) and evaluating the feasibility and utility of using pinpointIQ in the management of patients with COVID-19. Vital sign (physiology data) is collected to build a Covid Decompensation Index and contribute data to a Covid Digital Hub supported by the National Institutes of Health.
This multicentre prospective study will enroll a sufficient number of patients to afford approximately 60 positives and > 40 negatives (as determined by the SOC - Comparator method) in the United States and/or Canada. One to three sites in the United States and/or Canada will participate over an approximate 12-week enrolment period. The actual enrolment period will be dependent upon prevalence of Covid-19. Once positives sample size is achieved, expected SARC-CoV-2 negative subjects will be permitted. This study is observational and will not impact the medical management of the patient. The results of the Spartan Test will be blinded to the clinical staff during the study and will not impact the medical management of the subject. Once informed consent is obtained and eligibility is confirmed, subject demographics, and patient reported COVID-19 symptoms will be recorded. For the purposes of this study, enrolment will be defined as the collection of the two study-specific nasopharyngeal (NP) samples for Spartan's Test. Each patient's active involvement in the study will last for approximately 30 minutes. To support the EUA, a minimum of 30 individual natural positive clinical specimens will be collected from patients suspected of SARS-CoV-2 infection by a healthcare provider in COVID-19 disease endemic regions in the United States. Additionally, a minimum of 30 individual negative samples will also be used to support the EUA from patients in the United States. Once subjects are consented and recruited for the study, three nasopharyngeal samples for each patient will be collected by trained operators at the clinical site. The first sample will be tested at the clinical site according to standard of care protocols currently in place for the sites' nasopharyngeal swab-based SARS-CoV-2 RT-PCR testing. The second nasopharyngeal sample will be tested at the site using the Spartan COVID-19 v2 System. The third nasopharyngeal sample will be tested using the Spartan COVID-19 v2 System only when the test conducted with the second nasopharyngeal swab does not produce a positive or negative result. The sample for the SOC test will be collected prior to the samples for the Spartan COVID-19 v2 System as per clinical regulations.
This study is an adaptive, randomized, open-label, controlled clinical trial, performed worldwide in collaboration with WHO and INSERM.
This study will assess the efficacy and safety of DHODHi (brequinar) as an antiviral via 5 days of treatment of participants with positive COVID-19 and at least one symptom of COVI019 in an out-patient setting. The study is multi-center, randomized, and placebo-controlled.
The aim of this study will test the safety, tolerability, and efficacy of RLS-0071 for approximately 28 days in comparison to a placebo control in patients with acute lung injury due to COVID-19 pneumonia in early respiratory failure. Patients will be randomized and double-blinded for two parts, a single-ascending dose (SAD) part and a multiple-ascending dose (MAD) part. The name of the study drug involved in this study is: RLS-0071.
Recent studies have shown that some individuals may be asymptomatic but continue to shed the COVID-19 virus. These individuals may represent a population that can unknowingly transmit the virus. Healthcare workers (HCW) may acquire COVID-19 from the community or from possibly infected patients. It is important to gather data with respect to this to further understand the prevalence of asymptomatic carriage in individuals who work in research facilities, offices and clinical areas of hospitals and research facilities/institutes since this has important implications for infection control, as well as staff and patient safety. The purpose of this study is to test whether a proportion of these individuals may be asymptomatic shedders of the COVID-19 virus.
A feasibility RCT comprising two groups: 1. Intervention (SELF-BREATHE in addition to standard NHS care) 2. Control group (standard / currently available NHS care)
A Phase I/II clinical trial for safety and efficacy evaluation of treatment with anti-SARS-CoV-2 equine immunoglobulin (F(ab')2) in hospitalized patients with COVID-19 not requiring of invasive ventilation support.
Based on Chinese studies, cardiac injury occurs in 20-30% of hospitalized patients and contributes to 40% of deaths. There are many possible mechanisms of cardiac injury in COVID-19 patients and increased myocardial oxygen demand and decreased myocardial oxygen supply are likely contributors to increased risk of myocardial infarction and heart failure. Interventions reducing the risk of cardiac injury are needed. Ketone bodies, such as 3-hydroxybutyrate and acetoacetate, can maintain ATP production in the heart and brain during starvation. It has been suggested that ketone bodies are more efficient substrates of energy metabolism than glucose, with a lower oxygen consumption per ATP-molecule produced. In addition, the reduction in hospitalizations due to heart failure observed in type 2 diabetes patients treated with sodium-glucose cotransporter 2 inhibitors, is suggested to be partly attributable to increased levels of 3-hydroxybutyrate. Infusion with 3-hydroxybutyrate reaching a plasma level of approximately 3 mM had acute beneficial hemodynamic effects in patients with heart failure and in healthy controls in a study by Nielsen et al. Improved haemodynamics and reduced systemic oxygen consumption might be of great benefit in patients with COVID-19. The primary endpoint is left ventricular ejection fraction. Secondary endpoints are conventional echocardiography parameters, peripheral blood oxygen saturation, venous blood oxygen saturation and urine creatinine clearance. The study population are twelve previously hospitalized patients with COVID-19 The study design is a randomized placebo-controlled double-blinded crossed-over acute intervention study.
