NCT04355767
The overarching goal of this project is to confirm or refute the role of passive immunization as a safe and efficacious therapy in preventing the progression from mild to severe/critical COVID-19 illness and to understand the immunologic kinetics of anti-SARS-CoV-2 antibodies after passive immunization.The primary objective is to determine the efficacy and safety of a single dose of convalescent plasma (CP) for preventing the progression from mild to severe COVID-19 illness. The secondary objective is to characterize the immunologic response to CP administration. This study will enroll adults presenting to the emergency department (ED) with mild, symptomatic, laboratory-confirmed COVID-19 illness, who are at high risk for progression to severe/critical illness, but who are clinically stable for outpatient management at randomization.
NCT04575532
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.
NCT04320615
This study will evaluate the efficacy, safety, pharmacodynamics, and pharmacokinetics of tocilizumab (TCZ) compared with a matching placebo in combination with standard of care (SOC) in hospitalized patients with severe COVID-19 pneumonia.
NCT04332991
ORCHID is a multicenter, blinded, placebo-controlled, randomized clinical trial evaluating hydroxychloroquine for the treatment of adults hospitalized with COVID-19. Patients, treating clinicians, and study personnel will all be blinded to study group assignment.
NCT04292899
The primary objective of this study is to evaluate the efficacy of 2 remdesivir (RDV) regimens with respect to clinical status assessed by a 7-point ordinal scale on Day 14.
NCT04494724
The purpose of this study is to investigate the effectiveness and safety of treatment with clazakizumab compared to a placebo (inactive substance). We are proposing to try this drug to treat coronavirus disease 2019 (COVID-19) infection. Patients with COVID-19 infection have been shown to have increases in certain inflammatory processes. Clazakizumab is an antibody (immune system protein) that blocks certain inflammatory processes. The treatment plan is to attempt to inhibit or block these inflammatory processes in order to try to limit the damage COVID-19 causes to the lungs.
NCT01249625
Despite widespread use of respiratory protective equipment in the U.S. healthcare workplace, there is very little clinical evidence that respirators prevent healthcare personnel (HCP) from airborne infectious diseases. Scientific investigation of this issue has been quite complicated, primarily because the use of respirators has become "the standard of care" for protection against airborne diseases in some instances, even without sufficient evidence to support their use. The key question remains: How well do respirators prevent airborne infectious diseases? The answer to this important question has important medical, public health, political and economic implications.
NCT04504032
The purpose of this study is to assess safety and clinical efficacy of rivaroxaban in people with mild Coronavirus Disease 2019 who are at increased risk of disease progression.
NCT04334148
This is a double blind, placebo controlled study in approximately 2,000 health care workers at risk for being exposed to COVID-19. Eligible participants will be randomly assigned (1:1) to either treatment group (HCQ) or placebo in a double-blind fashion. Course of treatment is 30 days.
NCT04495764
This is a multi-center, prospective registry study of subjects undergoing hemodialysis for treatment of end-stage renal disease in a DaVita center. The objective of this study is to understand whether and to what degree anti-SARS-CoV-2 antibodies mitigate the risk of subsequent SARS-CoV-2 infection and COVID disease within the ESKD population.
NCT04350723
The aim of the COVI-PRONE Trial is to determine if early awake prone positioning in COVID-19 patients with hypoxemic respiratory failure; irrespective of the mode of oxygen delivery; reduces the need for invasive mechanical ventilation.
NCT04358081
Two recent studies have suggested that in patients with Covid19, treatment with hydroxychloroquine may shorten the duration of symptoms and improve viral clearance, an effect that appears most pronounced when combined with azithromycin. Hydroxychloroquine treatment may inhibit viral nucleic acid-mediated activation of various innate immune pathways, as well as blockade of lysosomal functions in cell types relevant for viral entry and antigen presentation. The purpose of the study was to determine if oral hydroxychloroquine monotherapy, or in combination with azithromycin results in clinical benefit in patients hospitalized with COVID19 pneumonia.
NCT04346199
CALAVI will investigate the safety, efficacy and pharmacokinetics of acalabrutinib together with Best Supportive Care in the treatment of COVID-19.
NCT04433546
This is a multicenter, randomized, double-blind, parallel group study to investigate the efficacy of pemziviptadil (PB1046) by improving the clinical outcomes in hospitalized COVID-19 patients at high risk for rapid clinical deterioration, acute respiratory distress syndrome (ARDS) and death. The study will enroll approximately 210 hospitalized COVID-19 patients who require urgent decision-making and treatment at approximately 20 centers in the United States.
NCT04465513
Corona virus disease 2019 (COVID-19) is caused by SARS-CoV-2, a plus-sense single-stranded RNA virus. After an incubation period, which typically lasts for 5-6 days, COVID-19 patients present with a mild illness that lasts for a few days. Common symptoms are reminiscent of the flu, and include fever, dry cough and dyspnea. A large percentage of patients resolve the infection whereas others progress onto adult respiratory distress syndrome (ARDS) which impedes gas exchange between the alveolar space and the bloodstream and creates the need for assisted respiration. The objective of this study is to investigate the safety and efficacy of CARDIO supplementation in the recovery of those with COVID-19 infection following the guidance from public health by reducing the need for mechanical respiratory support, alleviating respiratory symptoms and reducing mortality.
NCT04732819
SARS-CoV-2 vaccine, now being administered to skilled nursing facility (SNF) residents and staff, has highly variable acceptance between facilities. The investigators need to develop and disseminate effective strategies to increase vaccination immediately. For SNF residents and staff, the investigators will develop and implement a scalable multi-pronged intervention that educates, builds trust and supports the informed consent process aimed to increase SARS-CoV-2 vaccination. The investigators will conduct a cluster randomized trial to compare the effect of electronic messaging and education (i.e., usual care) versus a multi-pronged 'high touch' intervention to reduce vaccine hesitancy in skilled nursing facility staff and residents among a random sample of facilities across four SNF chains. As part of the 'high touch' intervention, the investigators will identify and train local opinion leaders. The investigators will offer these leaders assistance through real-time support for questions and provide consenting specialists. During the second wave of vaccination, the investigators will provide the intervention facilities with positive reinforcement for staff and will identify local champions to garner support and empowerment of staff. Finally, in the intervention facilities, the investigators will provide additional funds to support COVID-19 testing, in order that facilities have access to enough testing kits for patient or staff who develops symptoms following vaccination. This trial will be randomized within four SNF chains in order to evaluate the effect of a multi-pronged strategy to improve SARS-CoV-2 vaccine acceptance among direct care staff and long-stay nursing home residents. In four chains, eligible facilities will undergo randomization between usual care versus adding the 'high touch' intervention, implemented in two waves. Randomization and roll out of the intervention will occur at the facility level. The investigators hypothesize that: (1) the intervention will increase vaccination of SNF residents by at least 10 percentage points versus facilities usual care alone; (2) staff of SNFs with the intervention will have at least a 10 percentage point greater vaccine uptake of vaccine than staff in SNFs that do not participate in the high touch intervention; and (3) within intervention SNFs, improvements in vaccine uptake will be similar across staff and resident race/ethnicities.
NCT04338360
This expanded access program will provide access to investigational convalescent plasma for patients in acute care facilities infected with SARS-CoV-2 who have severe or life-threatening COVID-19, or who are judged by a healthcare provider to be at high risk of progression to severe or life-threatening disease.
NCT04540185
