461 Clinical Trials for Various Conditions
The 2019-2020 COVID-19 pandemic is the largest outbreak in recent history. It is not known how long after someone gets sick with COVID-19 and recovers that they can still infect other people. It is also not known how quickly people make antibodies against the virus, which help clear infection from the body. The investigators will enroll 300 people who had COVID-19 based on lab testing or confirmed exposure to participate. An additional 25 participants who have never tested positive for COVID and have not had the vaccine will be enrolled as negative controls. Participants will complete a survey at enrollment. The investigators will also collect blood, nose swab, saliva, stool, semen, and breast milk to test for the virus. The investigators will ask participants to complete a survey and give specimens up to 12 times over 24 months. This information will be used to study how long the virus can live in different parts of the body, antibody development, and post-infectious complications. The investigators hope that this information will allow medical and public health providers to make recommendations to better care for patients in the convalescent phase of COVID-19 infection.
This study will test whether an experimental vaccine to protect against severe acute respiratory syndrome (SARS) is safe, causes any side effects, and causes an immune response. SARS affects the respiratory system, usually starting with fever and muscle aches. Patients may get a dry cough and have difficulty breathing. Infection may be mild, but it can lead to death. Vaccines contain substances from an infectious agent, such as a virus, that, when injected into a person's body, stimulates production of antibodies that create resistance, or immunity, to that agent. The vaccine in this study contains genetic material (DNA) that codes for a protein found in the virus that causes SARS. Injected into a muscle, it instructs the body to make a small amount of a SARS protein. The vaccine is made from just one small part of the code for one SARS protein; a person cannot get SARS from the vaccine. Normal volunteers between 18 and 50 years of age who are in general good health may be eligible for this 32-week study. Candidates are screened with a physical examination and blood and urine tests. Participants have nine clinic visits during the study. They receive three vaccine injections, given with a system called the Bioinjector 2000® (Registered Trademark), which delivers the vaccine through the skin without the use of a needle. Following each injection, participants take home a diary card, on which they record their temperature and any vaccine side effects daily for 5 days. Participants must immediately report any symptoms to a study physician, and, if necessary, go to the clinic for an examination. Participants have the following tests and procedures: * Vaccine injections (study day 0, around week 4, and around week 8, with at least 21 days between injections) * Medical history and, if needed, physical examination (study day 0 and weeks 2, 4, 6, 8, 10, 12, 24, and 32) * Check of vital signs and weight (study day 0 and weeks 2, 4, 6, 8, 10, 12, 24 and 32) * Lymph node examination (day 0 and weeks 2, 4, 6, 8, 10 and 12) * Blood draw (study day 0 and weeks 2, 4, 6, 8, 10, 12, 24 and 32) * Pregnancy test for women (day 0 and weeks 4, 8 and 32) * Urine sample (day 0 and weeks 2, 4, 6, 8, 10)
This study will evaluate and treat people with SARS, a new type of pneumonia (lung infection) originating in China. SARS is caused by a new virus that is easily transmitted from person to person. This study will look at the course of the disease; determine how the virus affects the body and how the body fights the infection; and evaluate diagnostic tests to quickly identify the disease. People 18 years of age and older with probable or suspected SARS may be eligible for this study. Close contacts of patients with SARS, patients who recovered from SARS, and NIH health care workers involved in the care of patients will also be enrolled. Patients with SARS who require hospitalization will be admitted to the NIH Clinical Center. Because SARS spreads easily, hospitalized patients will be in a room by themselves and will not be allowed any visitors. They will not leave their room except for tests, such as x-rays. All participants will have a full medical examination, including a medical history, physical examination, and blood tests. In addition, the participants undergo various tests and procedures as follows: * Probable and suspected SARS patients may be hospitalized or may be seen as outpatients. They are provided the treatment judged best for their disease, usually according to expressed or published recommendations. The best treatment for SARS is not yet known, and there have been no studies evaluating therapies. Outpatients are seen three times a week for 2 weeks, once a week for 4 more weeks, and then at 6 months. Patients have mouth and throat swabs taken three times a week for the first 2 weeks, then once a week for 4 more weeks. Blood is drawn three times a week for the first 2 weeks, then once at weeks 3, 4, and 6. If virus is still detectable after 6 weeks, nose washings and throat swabs are repeated until no virus is detected for 3 weeks in a row. In addition, patients provide urine and stool samples, have a chest x-ray and electrocardiogram, and undergo bronchoscopy and bronchial lavage. For the bronchoscopy, a bronchoscope (pencil-thin flexible tube) is passed into the large airways of the lung, allowing the physician to examine the airways. Cells and secretions from the airways are rinsed from the lung with salt water. A brush the size of a pencil tip is passed through the bronchoscope to scrape cells lining the airways and pieces of tissue are collected for analysis. * Close contacts of patients are evaluated twice a week for 2 weeks, then once a week for 2 more weeks. Blood is drawn at the first visit and then at 1, 2, and 4 weeks. Mouth and throat swabs, nose washings, and sputum collections are done twice a week for 2 weeks, then once a week for 2 more weeks. Urine and stool samples are collected once a week for 4 weeks. If virus from the nose or throat is still detectable after 4 weeks, weekly nose washings and throat swabs continue until no virus is detected for 3 weeks in a row. Blood may also be drawn during the weekly visits. * Recovered SARS patients provide blood, urine, and stool samples and have a mouth and throat swab and nose aspiration to see if the SARS virus is present. For the nasal aspiration, salt water is put in the nose and then suctioned out. Usually, these tests are done only once. If virus is detected, however, the nose washing, throat swabs and blood tests are repeated once a week until no virus is detected for 3 weeks in a row. * Health care workers document their contact with patients, use of isolation procedures and equipment, and any unexpected events that occur during contact. They are evaluated for symptoms of infection and provide a blood sample once a month
Severe Acute Respiratory Syndrome (SARS) is a newly recognized illness that can be fatal. The purpose of this study is to better understand SARS by collecting samples of blood and other body fluids of people who have been exposed to SARS or who are suspected to have the illness. Up to 300 volunteers aged 18 years or older will be enrolled in this study. Participants will donate blood samples and, if appropriate, samples of fluid from the lungs, nose, or throat. Researchers will test these samples for proteins that control or mediate inflammatory or immune responses. The patterns of these proteins will reveal how SARS affects the body and the efforts the body makes to fight off the infection.
The purpose of this study was to evaluate the efficacy and safety of poractant alfa (Curosurf®), administered by endotracheal (ET) instillation in hospitalized adult patients diagnosed with SARS-COV-19 acute respiratory distress syndrome (ARDS).
This is a multi-center, randomized, triple-blind, placebo-controlled (RCT) study to evaluate the efficacy and safety of Dapsone in older adults, and/or in adult patients (≥40yrs of age) with at least one high-risk comorbidity, among those with confirmed SARS-CoV-2 infection. 3000 infected patients diagnosed with COVID-19, non-hospitalized at the time of enrollment, meeting all inclusion and no exclusion criteria will be randomized (1:1 allocation ratio) to receive either Dapsone or placebo tablets for 21 days, and will be followed up for 7 days after treatment termination for outcome assessment and up to 30 days for safety monitoring.
This is a phase 3, randomized, double-blind, placebo-controlled multicenter study to evaluate the efficacy and safety of colchicine in adult patients diagnosed with COVID-19 infection and have at least one high-risk criterion. Approximately 6000 subjects meeting all inclusion and no exclusion criteria will be randomized to receive either colchicine or placebo tablets for 30 days.
The scope of this study is to validate the Pine Trees Health COVID-19 Molecular Test with unique clinical specimens from across two (2) geographically diverse point-of-care testing sites in the United States. The results will be analyzed and compared against results from the CDC 2019- Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel. The primary objective is to generate clinical performance data for the Pine Trees Health COVID19 molecular diagnostic test in the point-of-care setting.
Severe acute respiratory syndrome (SARS-CoV2) due to novel Coronavirus (2019-nCoV) related infection (COVID-19) is characterized by severe ventilation perfusion mismatch leading to refractory hypoxemia. To date, there is no specific treatment available for 2019-nCoV. Nitric oxide is a selective pulmonary vasodilator gas used in as a rescue therapy in refractory hypoxemia due to acute respiratory distress syndrome (ARDS). In-vitro and clinical evidence indicate that inhaled nitric oxide gas (iNO) has also antiviral activity against other strains of coronavirus. The primary aim of this study is to determine whether inhaled NO improves oxygenation in patients with hypoxic SARS-CoV2. This is a multicenter single-blinded randomized controlled trial with 1:1 individual allocation
This Lucira COVID-19 All-In-One Test Kit performance study will be used to establish the performance of the Lucira COVID-19 All-In-One Test Kit as compared to a known high sensitivity RT-PCR molecular assay. The results of this study will be used to demonstrate the Lucira COVID-19 'swab to result in 30 minutes' test kit is similar in performance to known high sensitivity best-in-class molecular assays performed in high complexity labs. The results of this study will be combined with other studies the Sponsor has underway and will support a FDA Emergency Use Authorization (EUA) of the Lucira COVID-19 All-In-One Test Kit. This performance study will include nasal swabs self-collected by study subjects at community-based locations with trained medical staff. A subject's participation in this study will consist of one study visit and one collection event. The subject self-collects a nasal swab sample according to Lucira COVID-19 Test Kit instructions and runs test according to Quick Reference Instructions (QRI). Following the Lucira COVID-19 All-In-One Test Kit self-collection will be an additional swab collection for reference method testing. One (1) additional NS specimen will be collected either by the health care professional or self-collection, prepared in Transport Medium and sent to a reference laboratory.
The study is a double-blind, randomized, placebo-controlled, multi-center, Phase 3 study to evaluate the efficacy and safety of fostamatinib in COVID-19 subjects.

The clinical study is designed to evaluate the safety, tolerability and pharmacokinetics of inhaled nanoparticle nanoparticle formulation of Remdesivir (GS-5734) alone and in combination with NA-831 in 48 healthy volunteers.
The goal of this study is to evaluate the safety and effectiveness of Coronavirus-90 (COVID-19) convalescent plasma for the treatment of COVID-19. Plasma is the liquid part of blood that is left when all the blood cells have been removed. Convalescent means it is taken from people who were infected with COVID-19 and recovered. The use of this blood product to treat COVID-19 is investigational, which means the U.S. Food and Drug Administration has not yet approved it to be sold commercially. This is a human blood product collected by licensed blood banks. Donors of COVID-19 convalescent plasma must meet all standard blood donor criteria and must also meet all criteria set by the FDA for being a donor of COVID-19 convalescent plasma. A total of 500 patients will take part in the study at 8 hospitals within Beaumont. Similar studies are being done at other centers, but they are not directly related to this study. Participants will be assigned to a study group depending on how sick they are. * Group A: Those who require more than 6 liters (L) of supplemental oxygen but are not on a ventilator * Group B: Those who require a ventilator to preserve their life. Both groups will receive one unit (approximately 200ml or just under 1 cup) of COVID convalescent plasma. The transfusion will be given over about 30 minutes via an IV. Blood samples will be taken prior to and one hour after the transfusion to measure participant antibodies against Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) and a nasopharyngeal swab (deep in the nostril) will be taken to test for presence of the SARS-CoV-2 virus. One hour after the transfusion a blood sample will be taken to measure antibody levels to determine if the plasma caused the antibody level to rise. Similarly, blood samples will be taken to measure antibodies against SARS-CoV-2 and a nasopharyngeal swab will be taken to test for presence of the SARS-CoV-2 virus 1, 3 and every 7 days after the transfusion while the participant is in the hospital The participant's final health status will be determined on day 28. Hospital records will be monitored for 90 days after discharge to determine if the participant is readmitted to the hospital.
The study is a prospective, randomized, controlled investigation designed for comparison of two groups for the reduction of respiratory distress in a CoViD-19 population, using gammaCore Sapphire (nVNS) plus standard of care (active) vs. standard of care alone (SoC), the control group. The gammaCore® (nVNS) treatments will be used acutely and prophylactically. The aims of this study are to summarize and compare the incidence of clinical events and pro-inflammatory cytokine levels in patients randomized to use of gammaCore Sapphire plus standard of care vs standard of care alone in patients hospitalized for CoViD-19. Secondary objectives are demonstrate the safety of gammaCore Sapphire use in patients hospitalized for CoViD-19.
This phase I/II trial studies low-dose radiation therapy as a focal anti-inflammatory treatment for patients with pneumonia or SARS associated with COVID-19 infection.
Ideal new treatments for Novel Coronavirus-19 (COVID-19) would help halt the progression disease in patients with mild disease prior to the need for artificial respiration (ventilators), and also provide a rescue treatment for patients with severe disease, while also being affordable and available in quantities sufficient to treat large numbers of infected people. Low doses of Naltrexone, a drug approved for treating alcoholism and opiate addiction, as well as Ketamine, a drug approved as an anesthetic, may be able to interrupt the inflammation that causes the worst COVID-19 symptoms and prove an effective new treatment. This study will investigate their effectiveness in a randomized, blinded trial versus standard treatment plus placebo.
This is a clinical study for the prevention of SARS-CoV-2 infection in adults exposed to the virus. This study will enroll up to 2000 asymptomatic men and women 18 to 80 years of age (inclusive) who are close contacts of persons with laboratory confirmed SARS-CoV-2 or clinically suspected COVID-19. Eligible participants will be enrolled and randomized to receive the intervention or placebo at the level of the household (all eligible participants in one household will receive the same intervention).
Following the sudden and unexpected emergence of influenza A(H1N1)pdm09 (2009 H1N1) virus, this observational study was initiated to estimate rates of morbidity and mortality and to examine predictors of severity among participants with 2009 H1N1 infection. In 2011, as surveillance indicated that 2009 H1N1 virus was co-circulating with other seasonal influenza A and B viruses worldwide, the protocol was expanded to include other influenza A subtypes and influenza B viruses. The current version of the protocol (released in August 2013) further broadens the scope of this observational study. With the recognition that novel respiratory viruses other than novel influenza A viruses, e.g., Middle East Respiratory Syndrome Coronavirus (MERS-CoV), could become prevalent and of major public health importance, the objectives of this protocol have been expanded.
This study seeks to determine whether dual or quadruple therapy is more effective in treating COVID-19.
The investigators seek to derive and validate a clinically useful risk score for patients with Coronavirus Disease 2019 to aide clinicians in the safe discharge of patients.
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.
Previous research has shown that high dose intravenous vitamin C (HDIVC) may benefit patients with sepsis, acute lung injury (ALI), and the acute respiratory distress syndrome (ARDS). However, it is not known if early administration of HDIVC could prevent progression to ARDS. We hypothesize that HDIVC is safe and tolerable in Coronavirus disease 2019 (COVID-19) subjects given early or late in the disease course and may reduce the risk of respiratory failure requiring mechanical ventilation and development of ARDS along with reductions in supplemental oxygen demand and inflammatory markers.
Study KIN-1901-2001 is a multi-center, adaptive, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of gimsilumab in subjects with lung injury or acute respiratory distress syndrome (ARDS) secondary to COVID-19.
A randomized, double-blind, placebo-controlled, clinical trial of LY3127804 in participants who are hospitalized with pneumonia and presumed or confirmed COVID-19.
Individuals susceptible to SARS-CoV-2 and the illness it causes (COVID-19) are comprised of heterogeneous populations with a large risk spectrum for more severe disease. Pre-existing risk factors for a more severe course include respiratory and cardiovascular disease, morbid obesity, diabetes, underlying kidney or liver disease, and immunocompromised status. Whether children and young adults with inflammatory bowel disease (IBD) or juvenile idiopathic arthritis (JIA) receiving immunomodulating biologic and other therapies which are known to increase risk of viral infection are at increased risk of complications from COVID-19 or post-infectious co-morbidities, including the recently described multi inflammatory syndrome (MISC), is entirely unclear. This research focuses on the heretofore uncharacterized immune response to SARS-CoV-2 infection in children and young adults with IBD or JIA who are receiving maintenance immunosuppressive biologic therapies. Given the large Connecticut based infusion program, in a region of the United States with a recent large outbreak of COVID-19, the investigators have a unique opportunity to address a glaring knowledge gap in this unique pediatric, adolescent, and young adult population. The investigators will longitudinally determine antibody development and durability to SARS-CoV-2 in approximately 450-500 children and young adults with IBD or JIA receiving biologic therapy using a highly sensitive and specific quantitative assay utilizing novel technology. This period will include a return to school or work for many with likely resurgent infections, as well as the possible introduction of anti-SARS CoV-2 vaccines. The specific aim is to study the acute and convalescent antibody responses to SARS-CoV-2 infection in a cohort of children and young adults receiving infusions of biologic therapies for IBD and JIA.
