NCT04707664
The purpose of this research is to understand if the study drug, also called sargramostim or Leukine®, can help prevent the worsening of COVID-19 when the study drug is inhaled. This study will also help researchers understand if inhaled sargramostim can help prevent visits to the emergency room or hospitalization, or death.
NCT04360096
Brief Summary: SARS-CoV-2 virus infection is known to cause Lung Injury that begins as dyspnea and exercise intolerance, but may rapidly progress to Critical COVID-19 with Respiratory Failure and the need for noninvasive or mechanical ventilation. Mortality rates as high as 80% have been reported among those who require mechanical ventilation, despite best available intensive care. Patients with severe COVID-19 by FDA definition who have not developed respiratory failure be treated with nebulized ZYESAMI™ (aviptadil acetate, a synthetic version of Vasoactive Intestinal Polypeptide (VIP)) 100 μg 3x daily plus Standard of Care vs. placebo + Standard of Care using an FDA 501(k) cleared mesh nebulizer. The primary outcome will be progression in severity of COVID-19 (i.e. critical OR severe progressing to critical) over 28 days. Secondary outcomes will include blood oxygenation as measured by pulse oximetry, dyspnea, exercise tolerance, and levels of TNFα IL-6 and other cytokines.
NCT04713553
This is a Phase 3, randomized, observer-blind study in healthy individuals. The primary study will evaluate the safety, tolerability, and immunogenicity of the SARS-CoV-2 RNA vaccine candidate (BNT162b2): * As a 30-microgram dose, administered from 1 of 4 manufacturing lots (batches) * As a 20-microgram dose, administered from 1 of the manufacturing lots * As a 2-dose (separated by 21 days) schedule * In people 12 through 50 years of age The booster study will evaluate the safety, tolerability, and immunogenicity of 2 SARS-CoV-2 RNA vaccine candidates (BNT162b2 and BNT162b2.B.1.351): * Each as a 30-microgram dose * Each as a 1-dose booster vaccine, administered approximately 3 months after Dose 2 * In people 18 through 50 years of age
NCT04504734
This is a Phase 3, multi-center, randomized, double blind, placebo controlled, clinical study of bucillamine (2 dosage levels) in patients with mild-moderate COVID-19. Patients will be randomized 1:1:1 to receive bucillamine 100 mg 3 times a day (TID), bucillamine 200 mg TID or placebo TID for up to 14 days. After the first interim analysis when a single dose is selected, patients will then be randomized 1:1 to the selected bucillamine dose or placebo. This dose has now been chosen as 600 mg. The study will be overseen by an independent Data and Safety Monitoring Board (DSMB). Up to 50 centers in the United States will conduct this study. Up to 1000 patients will be enrolled in this study. Patients will participate in the study approximately 45 days.
NCT06047067
The goal of this clinical trial is to learn about the bioaerosol sampling device (BSD) and how it can sample patient bioaerosols (breath) and patient's nares for the detection of COVID-19 viral particles in patients seeking to be tested for COVID-19.
NCT04411680
The purpose of this research is to find out if a drug (sargramostim) also known as Leukine® could help patient recover faster from COVID-19. Sargramostim may help the lungs recover from the effects of COVID-19, and this research study will help to find this out.

NCT04745351
The primary objective of this study is to evaluate whether remdesivir (RDV, GS-5734™) reduces the composite risk of death or invasive mechanical ventilation (IMV) through Day 29 in participants with severely reduced kidney function who are hospitalized for coronavirus disease 2019 (COVID-19).
NCT04421508
A randomized, double-blind, placebo-controlled study to assess the efficacy and safety of pulsed inhaled iNO compared to placebo in subjects with COVID-19.
NCT04458298
The primary purpose of Stage-I of this study is to evaluate the safety and tolerability of OP-101 in patients with severe COVID-19 and of Stage 2 of this study is to evaluate the efficacy of OP-101 in patients with severe COVID-19. The secondary purpose of Stage 1 and Stage 2 of this study is to determine the effect of OP-101 reducing proinflammatory cytokines biomarkers in severe COVID-19 Patients. A further secondary objective of Stage 2 of this study is: To evaluate the safety and tolerability of OP-101 in patients with severe COVID-19.
NCT04732949
The purpose of this Phase III study is to confirm that SNG001 can accelerate the recovery of hospitalised patients receiving oxygen with confirmed Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2). Safety and other efficacy endpoints will also be assessed.
NCT04512079
Coronavirus Disease (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has led to unprecedented morbidity and mortality in the modern era. To date, nearly 13 million people have contracted COVID-19, leading to more than 550,000 deaths worldwide. As the number of affected individuals continues to climb, effective strategies for treatment and prevention of the disease are of paramount importance. SARS-CoV-2 is understood to directly invade cells via the human angiotensin-converting enzyme 2 (ACE2) receptor, which is expressed predominantly in the lungs but also throughout the cardiovascular system. Thus, while acute respiratory distress syndrome remains a feared complication, new thromboembolic disease has emerged as a common and potentially catastrophic manifestation of COVID-19.
NCT05800158
This prospective clinical performance study is a non-interventional, multi-center study to evaluate the assay performance of the COVID-19 test using upper respiratory specimens. Prospectively collected nasopharyngeal and anterior nasal swabs will be collected from each participant recruited in the study.
NCT05059080
This study will evaluate the long-term sequelae of COVID-19 in patients diagnosed with COVID-19 who previously enrolled in a RO7496998 (AT-527) study (i.e. parent study NCT04889040 \[CV43043\]), for approximately 6 months after the end of the parent study.
NCT05438498
If a treated cancer patient cannot make antibodies to a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Emergency Use Authorization (EUA) or approved vaccine, their risk for infection and its sequelae are significantly increased. The Astra-Zeneca Immuno-Suppressed Program (AISP) is designed to address whether a patient treated for cancer who receives a single-dose of Evusheld (AZD7442) 600 mg IM or IV will maintain a stable/protective effect against symptomatic SARS-CoV-2 infection including SARS-CoV-2 related hospitalization and/or SARS-CoV-2 related death up to 12 months post-baseline. The program will focus on patients with cancer who have been treated with chemotherapy, immunotherapy, targeted therapy, other therapy or combination therapy with or without radiation therapy within 12 months prior to enrollment, are willing/able to receive one IM or IV injection of Evusheld, are able to complete 14 Patient Experience/Clinical Outcome Assessment (COA) surveys, 6 Quality of Life (QoL) assessments and are willing to allow serum concentrations of Evusheld to be drawn 9 times, 3 SARS-CoV-2 Receptor Binding Domain-Immunoglobulin G (RBD-IgG) tests, and T-cell assay to be drawn once. In the event of a symptomatic break-thru SARS-CoV-2 positive infection by SARS-COV-2 Ribonucleic Acid (RNA) by Reverse Transcription Polymerase Chain Reaction (RT-PCR) test, the patient will have an additional Evusheld serum concentration, SARS-CoV-2 RBD-IgG antibody level and T-cell assay obtained in a temporally related manner. The program requires treatment with Evusheld 600 mg IM or IV.
NCT04354428
This is a randomized trial for the treatment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in high-risk adults not requiring hospital admission.The overarching goal of this study is to assess the effectiveness of interventions on the incidence of lower respiratory tract infection (LRTI) progression among high-risk adult outpatients with SARS-CoV-2 infection to inform public health control strategies.
NCT04780295
This online-based, observational retrospective registry aims to (i) study the rate of cardiovascular events, encompassing venous thromboembolic and arterial events, in consecutive hospitalized patients with coronavirus (Covid19), (ii) investigate the prevalent use of thromboprophylaxis, (iii) describe the use of imaging tests for the detection of cardiovascular events in patients with Covid19. This will also facilitate and constitute the basis for the conduction of interventional thromboprophylaxis studies in patients with Covid19.
