COVID19

This study tests whether a single infusion of hyperimmune immunoglobulin (hIVIG) — concentrated antibodies from recovered COVID-19 patients — can help adults at high risk (age 55+ or with weakened immune systems) who have early COVID-19. Participants receive either the antibody i…

This early-stage trial tests a biologic treatment for 20 people with moderate COVID-19 who also have controlled cancer. The treatment aims to help the immune system recognize and kill the virus. Researchers will check if the virus clears and if the immune response improves.

This study tests whether repeated doses of the BCG vaccine (originally for tuberculosis) can help adults with long-standing type 1 diabetes lower their blood sugar levels. About 150 participants receive either BCG or a placebo over 5 years, with follow-up for 10 years. The goal i…

This study tests whether giving inhaled anesthetics (isoflurane or sevoflurane) to sedate COVID-19 patients on ventilators can improve survival and reduce time on the breathing machine compared to standard IV sedatives. About 800 adults in the ICU with lung failure will be random…

This study planned to test whether putting a thyroid hormone (T3) directly into the lungs could help people with severe COVID-19 who need a breathing machine. The goal was to reduce fluid in the lungs and shorten time on a ventilator. However, the trial was withdrawn before any p…

This study tested whether using a baby shampoo nasal wash and Listerine mouthwash for 4 days could lower the amount of COVID-19 virus in the nose and throat of recently infected adults aged 18-65. Participants were randomly assigned to different wash combinations, including plain…

This phase 2 study tests whether fisetin, a natural compound found in fruits and vegetables, can reduce dangerous inflammation and improve oxygen levels in hospitalized COVID-19 patients. About 80 adults aged 60+ (or younger with certain health conditions) will receive either fis…

This study planned to test an inhaled medicine called Virazole (ribavirin) in adults hospitalized with COVID-19 who had serious breathing trouble. The goal was to see if the drug was safe and could improve oxygen levels. However, the trial was withdrawn before enrolling any volun…

This study uses a special bronchoscopy technique called narrow band imaging to look at blood vessel patterns in the airways of people with COVID-19. Researchers will compare images from three groups: patients with COVID-19, patients with other lung infections, and patients with l…

This study follows 98 elderly residents in French nursing homes to see how long their COVID-19 antibodies last. Researchers will also measure immune markers linked to aging to understand why some older people have weaker immune responses. The goal is to learn how to better protec…

This study aimed to collect medical information from people who developed unusual blood clots within four weeks of receiving a COVID-19 vaccine. The goal was to better understand any possible link between the vaccine and these rare events. However, the study was withdrawn before …

This study was designed to track how COVID-19 infection might worsen the condition of people with inherited metabolic diseases (IMD). Researchers planned to collect information from French patients with IMD who had or had COVID-19 to see how often their metabolic disease got wors…

This study uses special MRI scans with inhaled gases to see how lungs work in people with asthma, COPD, or COVID-19. Researchers will follow up to 160 participants over several years to track changes in lung function. The goal is to better understand why some patients struggle wi…

This study looks at organ changes in people recovering from COVID-19, comparing those with and without type 2 diabetes. Researchers will use scans to measure organ size and volume. The goal is to learn more about how COVID-19 affects the body long-term in diabetic patients.

This study tests whether changing how people interact in online social networks can improve their attitudes and intentions toward COVID-19 vaccination. Over 4,400 adults in the US with internet access will be placed into different online groups and answer health questions while s…

This study aimed to understand how undergraduate students and teaching staff at Misr International University in Egypt felt about online learning during the COVID-19 pandemic. Over 9,000 participants were asked about their satisfaction and knowledge through questionnaires. The go…

This study follows 500 adults who had COVID-19 to see what health problems they face months later. Researchers will track symptoms like tiredness, breathing trouble, and lung damage. The goal is to learn how common these long-term issues are and who is most likely to have them.

This study follows 1,000 Australians to see how well they follow COVID-19 rules like quarantine and distancing. Researchers also track the social, economic, and mental health effects of these measures. No treatment or vaccine is tested—the goal is to learn how to make public heal…

This study follows 200 hospital employees who received the AstraZeneca COVID-19 vaccine. Researchers measure their antibody levels at 6 weeks, 6 months, and 12 months after the second dose to see how long protection lasts. The goal is to understand the immune response and help gu…

This study is testing a tiny camera called micro OCT that can take detailed pictures of cells inside the lungs and nose. Researchers want to see if it works well in people with cystic fibrosis and other lung conditions. The goal is to eventually use this imaging to detect early d…

This small pilot study looks at how the gut microbiome might be linked to lingering symptoms after severe COVID-19. Researchers will measure changes in gut bacteria, immune markers, and lung function in 20 adults who had severe COVID in the past year. The goal is to find better w…

This study aimed to see if COVID-19 makes asthma worse or harder to control. Researchers planned to compare asthma patients who had COVID-19 with those who did not, tracking lung function and symptoms for a year. However, the study was withdrawn before enrolling anyone, so no res…
