Recruiting studies
- NCT03818334RecruitingPhase 2/Phase 3
Cyclophosphamide after transplant for blood cancer without sibling donor

Study early lung, virus, and gut changes in children with cystic fibrosis
This study looks at how a child’s early lung function, viral infections, and gut (microbiome) changes affect cystic fibrosis over time. It may help doctors understand what predicts how lung disease develops, which could improve future care.
BernAges birth–18 years - NCT04380038RecruitingPhase 4
Viral infection study in well-controlled asthma adults
This study looks at how a viral infection affects people with well-controlled asthma. It tests whether specific asthma-related immune signals can predict who reacts more to a virus, which may help guide future asthma care.
Charlottesville, VirginiaAges 18–40 - NCT04691622RecruitingPhase 1
Treat chronic norovirus using donor immune cells
This Phase 1 study tests whether giving immune cells made from a donor can help children and adults with long-lasting (chronic) norovirus infection. It’s aimed at people whose immune system is weakened after a stem cell transplant, solid organ transplant, or due to primary immune problems.
Washington D.C., District of ColumbiaAges 3 months–80 years - NCT04983823Recruiting
Study aims to improve long-term heart effects after COVID
This trial looks at how persistent heart-related changes after a past COVID infection may be affected by study treatments. It mainly seeks people who are stable enough for follow-up visits and heart imaging, and who are not already on the specific heart medications required.
Melbourne, VictoriaAges 50–85 - NCT05246098Recruiting
Rehabilitation program study for young and adult ICU COVID/respiratory survivors
This study looks at whether a rehabilitation approach improves recovery outcomes for people who survived COVID-19 or a serious breathing infection and needed ICU/PICU care. It may help those still dealing with physical or functional problems after their critical illness.
Calgary, AlbertaAges Any age - NCT05953233Recruiting
Air study in inner-city schools using home nasal swabs
This study looks at air in inner-city schools and how it may affect children’s health. You may be asked to collect nasal swab samples at home and answer questions, especially if your child’s classroom is part of the study.
Boston, MassachusettsAges 6–90 - NCT06416150Recruiting
Text message support for cervical cancer screening
This study aims to reduce gaps in cervical cancer care by using text messages to help people who have been referred for a colposcopy. If you qualify, you will receive text reminders and support to make sure you get the follow-up you need.
New Brunswick, New JerseyAges 18–90 - NCT06417762Recruiting
A study testing social media health messages for community health workers
This trial teaches community health workers how to find and share true health information on social media, and how to spot and stop false information. It aims to reduce illness from respiratory viruses in seven communities.
Chicago, IllinoisAges 18–99 - NCT06488118Recruiting
Lung response to inhaled immune stimulant in healthy and asthma
This study tests how the lungs react to breathing in a weak immune-stimulating drug (R848). It includes healthy volunteers and people with mild to moderate asthma to see differences in airway responses.
Cambridge, CambridgeshireAges 18–60 - NCT07062445Recruiting
Tracking treatment and outcomes for children with meningitis
This study follows children with meningitis to see how well treatments work and what happens in the long run. If your child has a fever and signs of meningitis (like a stiff neck, headache, or rash), they may be able to join.
São Paulo, São PauloAges Up to 17 years - NCT01011712Recruiting
Study immune causes of severe viral infections
This study looks at why some people have severe or unusual viral infections, even when they do not have a known immune problem. It collects blood and tissue samples to better understand possible inherited immune issues and may help future diagnosis and treatment.
Bethesda, MarylandAges 2–100 - NCT07512518Recruiting
Study of Long-Term Viral Brain Infections
This study follows patients with chronic viral infections affecting the brain and spinal cord. Researchers will collect spinal fluid samples and track your health over one year to better understand these infections and improve care.
Beijing, Beijing MunicipalityAges 14 years+ - NCT07645534RecruitingPhase 1
Testing a New Antiviral Medicine Formulation in Healthy Adults
This study compares two versions of an antiviral medicine called Ingavirin to see how your body processes them and whether they are safe. Researchers will give you the medicine on an empty stomach and after eating to understand how food affects how your body absorbs it.
Saint PetersburgAges 18–45 - NCT07662369RecruitingPhase 1/Phase 2
A trial of special immune cells for viral infections after transplant
This trial tests whether specially prepared donor immune cells can fight stubborn viral infections that did not get better with standard treatment. It is for people who have had a stem cell transplant and are still struggling with viruses like CMV, EBV, or others.
Shanghai, SHAges Any age - NCT05045612RecruitingPhase 4
Antibiotics for certain viral lung infections in hospitalized adults
This trial studies whether giving antibiotics affects recovery in adults hospitalized with moderately severe infections caused by specific viruses (influenza, parainfluenza, RSV, or hMPV). It may help show when antibiotics are helpful or unnecessary for viral airway illness.
BergenAges 18 years+ - NCT03418441Recruiting
Study infections of the brain and spinal fluid in Denmark
This trial focuses on people in Denmark who may have an infection in the brain or the fluid around the brain and spinal cord. Researchers aim to collect and compare diagnostic results for different infection types (viral meningitis, bacterial meningitis, encephalitis, and others) to help confirm the cause and guide care.
AalborgAges 18 years+ - NCT07359287Recruiting
Study on antibiotic use for respiratory infections
This study tests a program to help doctors prescribe antibiotics more carefully for common respiratory infections like colds, flu, bronchitis, and sinusitis. It may lead to better treatment for you.
CaenAges Any age - NCT06859333RecruitingPhase 1
Safety study of Ingavirin Forte in healthy volunteers
This trial tests how safe and tolerable different doses of Ingavirin Forte are in healthy people. It helps find the right dose for future studies.
MoscowAges 18–45 - NCT05332067RecruitingPhase 2
Omalizumab to prevent future asthma flare-ups before they start

This trial tests a new type of medicine that aims to wake up HIV hiding in your body's cells by targeting a viral protein called Tat. The goal is to help find a way to clear the virus completely.
MontpellierAges 18 years+ - NCT03810196Recruiting
Stem cell addback after transplant to treat viral or fungal infection
This study tests a stem cell “addback” treatment after a specific type of transplant (with certain immune cells removed). It may help the body recover faster and fight serious viral or fungal infections in children and teens.

Common questions
- Are there clinical trials for viral infection?
- Yes. Clin2 currently lists 99 recruiting viral infection 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 viral infection 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 viral infection 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.
