Recruiting studies
- 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.

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.

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?

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

Immune cells for BK or JC virus infections
This trial tests a treatment using special immune cells (called cytotoxic T lymphocytes) to fight BK or JC virus infections in people with weakened immune systems, such as cancer patients or organ transplant recipients. It may help control the virus and reduce related complications.
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+ - 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+ - NCT03818334RecruitingPhase 2/Phase 3
Cyclophosphamide after transplant for blood cancer without sibling donor
This trial studies giving cyclophosphamide after a stem cell transplant when there is no matched sibling donor, but a well-matched unrelated donor is available. It aims to improve outcomes for people with blood cancers undergoing this transplant.

Common questions
- Are there clinical trials for viral infection?
- Yes. Clin2 currently lists 94 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.
