Houston, TexasAges Any age - NCT04448145Recruiting
Study why COVID lasts after recovery
This study looks at what factors may make COVID-19 symptoms or infection effects last after someone has recovered. It also collects certain body samples to better understand why this persistence happens.
New York, New YorkAges 7 years+ - NCT04429594Recruiting
Study tracking COVID-19 infection rates in the public
This study looks at how often SARS-CoV-2 (the virus that causes COVID-19) infection happens in people who may have been exposed in the community. It may help researchers understand infection rates and patterns in the general population.
NiceAges 18 years+ - NCT04326426Enrolling by invitationPhase 3
Study of tradipitant for severe or critical COVID-19
This trial tests whether tradipitant can improve outcomes for adults with severe or critical COVID-19, including pneumonia and low oxygen. It may help patients whose lungs are significantly affected and who need careful hospital-level care.
New York, New YorkAges 18–90 - NCT04344119Recruiting
Study of chilblains during COVID-19 infection
This study looks at skin lesions (chilblains) that appear in people with a confirmed COVID-19 infection. It aims to better understand these skin changes.
NiceAges Up to 90 years - NCT04367857Recruiting
Study of COVID antibody levels in healthcare workers
This study measures how many healthcare workers have COVID antibodies (proof of past infection or immune response). Results may help estimate how widespread COVID exposure has been among hospital staff.

DAS181 treatment for COVID-19 lung infection in immune-compromised adults
This Phase 3 trial tests DAS181 to treat lower lung (chest) viral infections in people with weakened immune systems, including a COVID-19 subgroup. It may help by targeting certain viruses in the lungs, but joining depends on your oxygen needs, recent diagnosis, and other safety factors.
Duarte, CaliforniaAges Any age - NCT04382846RecruitingPhase 3
Testing new treatment combinations for COVID-19
