Recruiting studies
- 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+ - NCT04474301Recruiting
Quality of life check for people with melanoma during COVID-19
This study looks at how people with melanoma are feeling during the COVID-19 pandemic, including quality of life. You may be asked to share information through surveys or study contact so the researchers can understand needs and concerns.
Houston, TexasAges Any age - NCT04486638Recruiting
Dengvaxia pregnancy registry in the US
This registry collects information about people who were pregnant and exposed to the Dengvaxia vaccine during pregnancy, to better understand outcomes after that exposure. It may help future mothers and clinicians by building a clearer safety and health record over time.

Durvalumab and tremelimumab with chemotherapy for advanced lung cancer in HIV
This trial tests a combination of immune therapy drugs (durvalumab and tremelimumab) given with chemotherapy in people with stage IV non-small cell lung cancer who also have HIV. It may help shrink or control cancer by boosting the immune response while keeping HIV well controlled.

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 - NCT04512456Recruiting
Exercise training study for people with HIV and heart health
This study looks at how a structured exercise program affects the heart and blood flow in people living with HIV. It may help your care team understand who benefits most from exercise and how to do it safely.

Study of how COVID-19 affected surgery patients
This study looks at how the COVID-19 pandemic changed outcomes and experiences for people who had surgery in Stockholm during the study period. It may help hospitals prepare better plans for patients during future outbreaks.
StockholmAges Any age - NCT04527705Recruiting
Testing endodontic retreatment in one versus two visits
This study compares doing tooth root-canal retreatment in one visit versus two visits. It’s meant to see which approach leads to better outcomes for teeth with infection at the root tip (apical periodontitis).
Sant Cugat del Vallès, BarcelonaAges 18–75 - NCT04545242RecruitingPhase 4
Dexamethasone for severe lung failure from infections on ventilators
This trial studies whether dexamethasone (a steroid medicine) improves outcomes in adults who have sudden, severe breathing failure caused by an infection while they are on a breathing machine. It may help reduce inflammation in the lungs during critical illness.
Terrassa, BarcelonaAges 18 years+ - NCT04551378Recruiting
Study of how COVID affected young people with cancer
This study looks at how the COVID-19 pandemic affected the experiences of teenagers and young adults with cancer, including people who finished treatment. It may help improve support for cancer patients and survivors during public health crises.
Houston, TexasAges 18–39 - NCT04577313Recruiting
Study to improve HIV medicine adherence reminders
This study looks at a way to help people take their HIV medicines as prescribed. It focuses on people who are HIV-positive and not currently taking their treatment consistently.
Storrs, ConnecticutAges 18 years+ - NCT04579588Recruiting
Study flu vaccine immunity in people after COVID-19
This study looks at how well your immune system (your body’s infection-fighting system) responds to a flu vaccine after you’ve had COVID-19. It may help doctors understand why some people have different protection after vaccines.
Palo Alto, CaliforniaAges 9–64 - NCT04582903Recruiting
Send-in sample collection study for immune response to respiratory viruses
This study collects sent-in samples to better understand how your immune system responds during a COVID-19–like illness and after you recover. It may help researchers learn why some people get sick and others stay uninfected, and how immune protection works over time.
Rockville, MarylandAges 1 day–99 years - NCT04588402Recruiting
Tests whether HPV vaccination prevents cervical HPV infection in young women
This study looks at whether HPV vaccination lowers the chance of getting HPV in the cervix. It will collect cervical samples and ask questions to see how vaccination affects infection in women in Sikkim, India.
Gangtok, SikkimAges 18–22 - NCT04605445Recruiting
One vs two dentist visits for infected root canals
This study compares whether treating an infected, dead tooth in one visit works as well as using two visits. It may help you and your dentist choose the simplest schedule while still clearing infection and supporting healing.
Vaxjo, Kronoberg CountyAges 18 years+ - NCT04624490RecruitingPhase 1
Lung function MRI using a special gas in volunteers
This Phase 1 study tests a lung scan that uses a special gas and MRI to measure how well your lungs work. It includes healthy volunteers and people with lung disease to see how well the scan works and how safe it is.
Kansas City, KansasAges 3 years+ - NCT04645199Recruiting
Long-term follow-up study for blood and bone marrow diseases
This study is collecting long-term follow-up information from people diagnosed with certain blood and bone marrow conditions. It may help doctors understand what happens over time and improve future care, but you’re mainly contributing data rather than receiving a new treatment.
Tianjin, Tianjin MunicipalityAges Any age - NCT04647331Recruiting
Study antibiotic levels in heart valve infection
This trial measures how your body handles certain intravenous antibiotics used for endocarditis, an infection of the heart valves. It may help doctors understand the best antibiotic dosing for people with valve infections.
GothenburgAges 18 years+ - NCT04653610Recruiting
Study immune signals in untreated HIV using extra samples
This study looks at tiny cell “messengers” in blood and stool to understand how HIV behaves before and after starting treatment. You may be eligible if you have untreated HIV (or you’re a healthy volunteer) and can commit to many sample visits, including long-term storage for 20 years.
Ghent, Oost-VlaanderenAges 18–65 - NCT04664556Recruiting

- Are there clinical trials for infections?
- Yes. Clin2 currently lists 1,767 recruiting infections studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a infections trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a infections trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
