Recruiting studies
- NCT04359836Recruiting
Study of gut bacteria in early COVID-19
This trial studies how gut bacteria (“gut flora”) may affect COVID-19 after a recent infection. If you test positive for COVID-19 soon enough, the study may help researchers understand why some people get better faster or have different symptoms.
Ventura, CaliforniaAges 18 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.
New York, New YorkAges 18 years+ - NCT04573062Recruiting
Study how people recover from COVID over time
This study follows adults who recently recovered from COVID-19 to better understand what happens during recovery and afterward. It may help researchers identify who is at risk for longer-lasting symptoms (often called “PASC”) and what changes over time.
Bethesda, MarylandAges 18–100 - NCT06667700RecruitingPhase 3
A study of the antiviral molnupiravir for high-risk people with COVID-19
This study tests an antiviral pill called molnupiravir to see if it can prevent severe COVID-19 in people who are at high risk and cannot take Paxlovid. If you have mild to moderate COVID-19 symptoms and certain health risks, you may be able to join.
Cullman, AlabamaAges 18 years+ - NCT07743580RecruitingPhase 3
Secutrelvir for covid-19 patients at high risk
This trial tests a new antiviral pill, secutrelvir, for people with mild to moderate covid-19 who are at higher risk of getting seriously ill. It aims to see if the drug can prevent hospitalization or severe disease.
Coral Gables, FloridaAges 12 years+ - NCT04278404Recruiting
Drug safety study for children already on certain medicines
This study measures how certain medicines move through the body and checks their safety in children. It may help doctors better understand dosing and side effects in kids who are already receiving these treatments, or in some kids who recently tested positive for COVID-19.
Phoenix, ArizonaAges birth–20 years - NCT05656105RecruitingEarly Phase 1
PET scan study of brain inflammation after COVID
This early-phase study uses a special PET scan to look for signs of brain inflammation in people with ongoing (long-term) nervous system symptoms after COVID-19. It may help researchers understand what is driving symptoms and whether this imaging approach can detect inflammation.
Birmingham, AlabamaAges 18–65 - NCT04318366Recruiting
Study of COVID-19 samples and how patients respond to treatment
This trial collects and studies COVID-19 test results and other patient information to better predict treatment response and outcomes. Your sample(s) help researchers understand who may improve, worsen, or need different care.
Milan, LombardyAges 18 years+ - NCT04320732Recruiting
Study COVID-19 spread at home and work
This study looks at what factors make COVID-19 spread more easily in the community and workplace. It may help researchers understand how to reduce transmission in everyday settings.
OsloAges 18 years+ - NCT04327570Recruiting
Study of immune responses in hospitalized COVID-19 patients
This study looks closely at how your immune system responds during COVID-19. It may help researchers better understand why COVID-19 varies from person to person and how to improve future care.
LeuvenAges 18 years+ - NCT04330521Recruiting
Cancer patients share experiences during the COVID-19 outbreak
This study asks adult cancer patients to complete a survey and talk in an interview about how COVID-19 affected their care and daily life. Your answers may help researchers understand what challenges cancer patients faced during the pandemic.
Stanford, CaliforniaAges 18–99 - NCT04362150Recruiting
Study of long-term effects after COVID-19 infection
This study follows adults who had COVID-19 to learn how the illness can affect health over the long term. It may help researchers understand lasting symptoms and who is at higher risk, which could improve future care.
San Francisco, CaliforniaAges 18–100 - 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+ - NCT04510025Recruiting
MRI study of whole-body effects of moderate to severe COVID
This study looks at how COVID-19 affects multiple organs in the body, using MRI scans and related measurements. It may help researchers better understand who is at risk for longer-lasting or widespread effects after COVID.
OxfordAges 18–100 - NCT04772170Recruiting
Study wearable and symptom monitoring during respiratory virus challenges
This observational study looks for digital health patterns during studies where people are intentionally exposed to a respiratory virus. If you join a respiratory virus challenge at NIH, you may help researchers discover better ways to monitor and understand illness using wearable devices and shared health data.
Bethesda, MarylandAges 18–65 - NCT04887623Recruiting
Blood and breathing marker tracking in hospitalized COVID-19
This study follows hospitalized people with recent COVID-19 to see how infection and inflammation markers change over time. It may help doctors better understand what’s happening in the body as breathing problems develop and treatments are given.
Hradec KrálovéAges 18–90 - NCT05141058RecruitingPhase 1
T cell therapy to help prevent COVID-19 after transplant
This Phase 1 trial tests a donated immune-cell treatment (T cells) to help immunocompromised people fight or resist COVID-19 after they recently received a bone marrow or stem cell transplant. It aims to see if the treatment is safe and if it helps the body respond better to the virus.
Washington D.C., District of ColumbiaAges 2–80 - NCT05164744Recruiting
MRI study of heart tissue changes after COVID-19
This study uses a heart MRI to look for leftover (healing) changes in heart tissue after COVID-19. It may help researchers better understand what ongoing heart effects can happen after infection.
Brooklyn, New YorkAges 18 years+ - NCT05188612Recruiting
Hospital patients with confirmed COVID-19 survey study
This study collects information from adults who are in the hospital for confirmed COVID-19. The goal is to better understand what happens during acute (early) COVID-19 and improve care.
Bologna, BolognaAges 18 years+ - NCT05868239Recruiting
Testing an aerosol box during CPR emergencies
This study tests whether using an aerosol “box” during cardiopulmonary resuscitation (CPR) during an emergency improves safety and care. It’s mainly aimed at trained healthcare staff who can perform required tasks during CPR.
Los Angeles, CaliforniaAges 18–60 - NCT06099795Recruiting
Breath test vs. swab test for COVID-19
This study checks if a new breath test (eBAM-CoV) can accurately detect COVID-19 compared to the usual nose/throat swab test (RT-PCR). If you have symptoms or were exposed and are getting tested anyway, you may be able to help by also providing a breath sample.
NîmesAges 18 years+ - NCT06631287RecruitingPhase 3
Testing baricitinib for persistent long COVID symptoms
This trial tests whether the anti-inflammatory drug baricitinib can improve persistent long COVID symptoms like brain fog, fatigue, and shortness of breath. You may qualify if you had COVID-19 at least 6 months ago and still have bothersome symptoms that affect your daily life.
Tucson, ArizonaAges 18 years+ - NCT06667063Recruiting
