- NCT07601412Recruiting
Understanding Immune Response to Respiratory Viruses in Older Adults
This study examines how the body's natural defense system (specifically a type of immune protein) responds to common respiratory viruses like flu and cold in older adults. Researchers will analyze nasal samples that are already being collected as part of routine care to better understand why older people sometimes have different immune responses to these infections.
LyonAges 60 years+ - NCT04230356RecruitingPhase 2
Viral immune T-cells for viral infections after stem cell transplant
This Phase 2 study tests donor-made immune T-cells that specifically target viruses to treat or prevent viral infections after a stem cell transplant. It may help your body control dangerous viruses like adenovirus, CMV, EBV, and BK virus, while checking safety with different timing of the treatment.
Cincinnati, OhioAges Any age - NCT02532452RecruitingPhase 2
T-cells made to fight a specific virus
This Phase 2 study gives you special “virus-targeting” immune cells (T-cells) to help your body control a current viral infection or virus that has come back (reactivated). It may help reduce the virus activity while you are immunocompromised, meaning your immune system is weaker than usual.
Akron, OhioAges 2 days+ - NCT06178822Recruiting
New blood tests to diagnose sepsis in the ER
This study aims to find new ways to quickly diagnose sepsis (a severe response to infection) in patients arriving at the emergency room. If successful, these new tests could help doctors start treatment faster.
Almere Stad, FlevolandAges 18 years+ - NCT06286657Recruiting
Xanthohumol and viral infections study
This study tests whether a natural compound called xanthohumol (found in hops) can help your body fight off common viruses. Healthy adults with a normal BMI are invited to participate.
ViennaAges 18–70 - NCT07222670RecruitingPhase 2
Study of INNA-051 to prevent viral respiratory illness in healthy adults
This trial tests whether INNA-051 can help prevent respiratory infections caused by viruses in healthy adults aged 18 to 45. It may be an option if you are at higher risk of catching such infections due to your living or work situation.
Baltimore, MarylandAges 18–45 - NCT07030673Recruiting
Stopping antibiotics early in older adults with viral infections
This trial tests whether elderly patients hospitalized with a viral lower respiratory infection can safely stop antibiotics early. It aims to reduce unnecessary antibiotic use and side effects.
AmiensAges 65 years+ - NCT07420985RecruitingPhase 2
Ingavirin forte for flu and other viral infections
This trial tests different doses of Ingavirin Forte capsules for treating influenza and other respiratory viruses. It may help people with fever, cough, sore throat, and body aches who have been sick less than 48 hours.
IvanovoAges 18–65 - NCT05336851Recruiting
Emergency breathing test study for sudden lung infections
This trial tests an emergency breathing-related approach for adults with a sudden, community-acquired respiratory infection. It may help doctors quickly sort out what’s going on and guide early care.
Hong KongAges 18–100 - NCT02048332RecruitingPhase 1/Phase 2
Donor immune cells for preventing infections after stem cell transplant
This trial studies donor-made immune cells (T-cells) given after a stem cell transplant to help your body fight infections. It aims to test how safe the treatment is and whether it supports the immune system in the months after transplant.
Akron, OhioAges 4 weeks+ - NCT07110636Recruiting
Blood test for infection in immunocompromised adults
This trial tests a blood test that looks for infection by analyzing tiny bits of DNA from microbes. It may help find infections faster in people with weakened immune systems, such as transplant recipients or those with blood cancers.
San Francisco, CaliforniaAges 18 years+ - NCT06931002Recruiting
Cold virus study in bronchiectasis and healthy volunteers
This study tests whether giving a common cold virus (rhinovirus) to people with bronchiectasis and healthy volunteers can trigger a lung flare-up. It aims to understand how the immune system responds and what causes exacerbations, which could lead to better treatments.
LondonAges 18–65 - NCT05123755RecruitingPhase 2
Testing a new medicine in hospitalized pneumonia patients needing oxygen
This Phase 2 trial tests an investigational medicine (given in increasing doses) for hospitalized people with pneumonia who need supplemental oxygen. It aims to see if the medicine is safe and potentially helps the pneumonia process in the early hospital period.
Newport Beach, CaliforniaAges 18 years+ - NCT05624450RecruitingPhase 3
Test drug tozorakimab for hospitalized viral lung infection needing oxygen
This Phase 3 study tests tozorakimab to see if it helps people hospitalized with a viral lung infection that is causing low oxygen levels. You might qualify if you still need supplemental oxygen when the study starts.
Birmingham, AlabamaAges 18 years+ - NCT05603650Recruiting
Mouthwash study for healthy bacteria in your mouth and gut
This study tests how a mouthrinse changes the helpful bacteria in your mouth and stomach/gut. You may need several visits and phone follow-ups to see how your microbiome shifts over time.
Irvine, CaliforniaAges 18 years+ - NCT07249996Recruiting
Respiratory infections in young babies
This study watches babies under 29 days old to track and understand respiratory infections. It may help doctors learn how to better protect very young infants.
Cali, Valle del Cauca DepartmentAges Up to 4 weeks - NCT07635368Recruiting
Blood Markers in Newborns With CMV Infection
This research study examines blood samples from newborns to identify biological markers (proteins and genetic signals) that could help detect and understand congenital cytomegalovirus (CMV) infection—a virus some babies are born with. Finding these markers might help doctors identify infected infants earlier and develop better treatments.
CopenhagenAges birth–4 weeks - NCT05550298Recruiting
Study of virus infections after pediatric transplants
This study looks at how respiratory viruses behave and how the body responds in children who are about to receive, or have recently received, a transplant. It may help doctors better diagnose and treat viral infections in transplant patients by studying blood samples and test results.
Birmingham, AlabamaAges Up to 18 years - NCT06841913RecruitingPhase 4
Woodsmoke, flu, and your nasal immune response
This study tests how breathing woodsmoke affects your nose's ability to fight off the flu virus. You will be exposed to woodsmoke and then given a live flu vaccine to see how your immune system responds.
Chapel Hill, North CarolinaAges 18–49 - NCT07066540Recruiting
Trial of Reamberin for Viral Stomach Infections in Children
This trial tests if the drug Reamberin, given through an IV, can help children aged 1 to 6 recover faster from a viral stomach infection. It's for kids who need fluids through a vein and have symptoms like vomiting, fever, and tiredness.
ChelyabinskAges 1–6 - NCT06155266Recruiting
Blood test to tell bacterial vs viral infection
This trial uses a simple blood test to help doctors quickly tell if your infection is caused by bacteria or a virus. It only requires a small extra blood sample taken during your regular emergency visit.
ParisAges 18 years+ - NCT06999603RecruitingPhase 2
Inhaled study drug for virus infections on ventilators
This study tests an inhaled study drug (SNG001) for adults on a breathing machine in the ICU due to a viral lung infection. The goal is to see if the drug can help patients recover faster.
Sacramento, CaliforniaAges 18 years+ - NCT06500767Recruiting
Emotional impact of counseling before colposcopy
This study looks at how counseling before a colposcopy affects your emotions and mental well-being. You may take part if you have abnormal cervical screening results and need a closer exam.

Common questions
- Are there clinical trials for viral infection?
- Yes. Clin2 currently lists 100 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.
