Recruiting studies
- NCT05183490RecruitingPhase 1
Cell therapy for repeated viral infections after transplant
This early-phase (Phase 1) study tests an immune cell treatment (R-MVST) to help people whose immune system has been weakened by a past transplant and who keep getting viral infections reactivated or not responding well to standard treatment. It may help your body control viruses like EBV, CMV, adenovirus, or BK virus.
New York, New YorkAges 18 years+ - NCT04013802RecruitingPhase 1
Multivirus T-cell treatment for EBV, CMV, adenovirus, and BK after transplant
This Phase 1 study tests an “off-the-shelf” type of immune cell therapy made to attack several viruses (EBV, CMV, adenovirus, and BK, and possibly JC) in people who had an allogeneic stem cell transplant and still have ongoing viral infection. It may help your body control the virus when standard treatments have not worked or you cannot tolerate them.
Houston, TexasAges Any age - NCT07536035Recruiting
Comparing Hospital Care Pathways for Acute Medical Illness
This study compares two different hospital care pathways for adults admitted with acute medical emergencies like infections, falls, or COPD flare-ups. The goal is to see which pathway provides more appropriate and effective care.
SingaporeAges 21 years+ - NCT07261969Recruiting
Blood test and leaflet to guide antibiotic use for respiratory infections
This trial tests if a quick blood test (C-reactive protein, CRP) and a patient leaflet can help doctors prescribe antibiotics only when needed for adults with respiratory tract infections. It aims to reduce unnecessary antibiotic use.
Sokuluk Village, Chui RegionAges 18–70 - NCT00006518Recruiting
Tissue samples from people with viral infections or cancer
This study collects tissue and blood samples from people who have or have been exposed to certain viruses (HIV, KSHV, HPV, EBV, or HTLV-1) or who have developed cancer or precancerous skin lesions. The samples help researchers understand how these viruses may lead to cancer.
Bethesda, MarylandAges 18 years+ - NCT05492565Enrolling by invitation
Follow-up study for people on HIV prevention pills
This study follows adults who are at high risk of getting HIV while they take HIV prevention pills (PrEP). It aims to learn how well PrEP fits real-life use in people at risk and who may need extra care.
Seville, AndalusiaAges 18 years+ - NCT07633288RecruitingPhase 2
AP1189 Safety and Efficacy for Severe Respiratory Viral Infection
This trial tests whether an experimental drug called AP1189, added to standard hospital care, can help people hospitalized with severe breathing problems from viruses like COVID-19, flu, or RSV. The goal is to see if it reduces the need for mechanical ventilation or other life support.
Mostar, Herzegovina-Neretva CantonAges 18 years+ - NCT07388173Recruiting
How respiratory infections affect daily life in older adults
This study looks at how acute respiratory infections (like the flu, COVID-19, or RSV) affect older adults' daily functioning. If you are 60+ and in the hospital with one of these viruses, your participation would help doctors understand the lasting impact on independence and health.
Rochester, New YorkAges 60 years+ - NCT07041671Recruiting
Can a mouth spray reduce virus in breath?
This trial tests whether ColdZyme mouth spray can lower the amount of virus you breathe out when you have a cold or flu-like illness. It may help you recover faster and reduce spreading the virus to others.
LundAges 18 years+ - NCT02007356RecruitingPhase 2
Donor immune cell infusions for viral infections after stem cell transplant
This trial studies whether directly infusing donor-made immune cells (virus-fighting T-cells) is safe and feasible in people who still have viral infections after a stem cell transplant. It may help your body control infections from adenovirus, CMV, or EBV when standard antiviral treatments aren’t working.
BaselAges 18–65 - NCT07685457Recruiting
Virus-specific T cells for stubborn viral infections after transplant
This trial tests whether specially trained immune cells (virus-specific T cells) can safely treat stubborn viral infections after a stem cell transplant. It focuses on children and young adults who have not responded to standard antiviral treatments.
SeoulAges 1–25 - NCT02479698RecruitingPhase 2
T Cell treatment for cancers and BK/JC virus illness
This trial studies an infusion of “cytotoxic T lymphocytes” (immune cells) to treat people with certain cancers or illnesses caused by BK and/or JC viruses. It may help your immune system fight the virus and related organ complications when standard treatments have not worked well enough.
Houston, TexasAges Any age - NCT07278700Recruiting
Fever and respiratory infection study
This study looks at adults with a fever caused by a respiratory infection. If you qualify, you will have a blood draw as part of your regular care, and researchers will use it to learn more about your condition.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT04197596RecruitingPhase 1/Phase 2
BK infection immune-cell treatment after transplant or weak immunity
This Phase 1/2 study tests lab-made immune cells that specifically target BK virus in people whose BK infection keeps coming back or doesn’t improve. It may help by boosting the body’s ability to clear the virus, especially when standard antiviral treatments don’t work or can’t be tolerated.
San Francisco, CaliforniaAges 1 month–79 years - NCT06926894RecruitingPhase 1
A cell therapy for viral infections in children and young adults
This trial tests a special immune cell treatment (R-MVST cells) for children and young adults who have had a stem cell or organ transplant and are fighting stubborn viral infections like EBV, CMV, ADV, or BK virus. The goal is to see if these cells can help control the viruses when standard medicines haven't worked well enough.
New York, New YorkAges 3 months–26 years - NCT07347769Recruiting
BK virus risk study in kidney transplant patients
This study looks at the type and genetic makeup of BK virus in kidney transplant patients and their donors. It aims to find patients at higher risk for a kidney infection caused by the virus, which could help improve monitoring and treatment.
GrenobleAges 18 years+ - NCT04099082Recruiting
Predicting lung scarring after a specific viral infection
This study looks at how your immune response to a particular virus (PIV) might predict future lung scarring called bronchiolitis obliterans. It may help doctors better identify who is at higher risk after a stem cell transplant.
Paris, Île-de-France RegionAges 18 years+ - NCT06625944Recruiting
How viral infections affect lung disease
This study looks at how viral infections impact people with chronic lung conditions like COPD or bronchiectasis. It aims to understand symptoms and triggers better, which could help improve future treatments.
LondonAges 18 years+ - NCT05334706RecruitingPhase 4
Vaccine study to lower HPV spread in HPV-positive women
This Phase 4 study tests whether a 9-type HPV vaccine (9vHPV) can reduce how infectious HPV is and lower the chance of HPV spreading in women who already have HPV16 and/or HPV18. It focuses on specific HPV-positive women recently diagnosed and compares what happens after vaccination.
L'Hospitalet de Llobregat, CataloniaAges 18 years+ - NCT06715891RecruitingPhase 3

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.
