Recruiting studies
- NCT07225972RecruitingPhase 3
Immune cells from a family donor for stubborn virus infections after stem cell transplant
This trial is testing whether giving special immune cells from a family donor (called CTLs) along with regular antiviral medicine is better than regular medicine alone for people who have a stubborn adenovirus or cytomegalovirus infection after a stem cell transplant.
Valhalla, New YorkAges 1 day–30 years - NCT05784038Recruiting
Study of monkeypox infection in Brazil
This is an observational study that follows people with confirmed monkeypox (mpox) to better understand the illness over time. It may help doctors learn what to expect and improve care, but it does not test a new treatment.
Belém, ParáAges 18 years+ - NCT05195450Recruiting
Tenofovir to stop liver disease in mild hepatitis B
This trial tests tenofovir alafenamide (a hepatitis B antiviral medicine) to see if it can prevent liver disease from getting worse in people with chronic hepatitis B who currently have stable (normal) liver blood tests and low virus levels. It may help lower the chance of developing serious liver complications over time.
New Delhi, National Capital Territory of DelhiAges 18–70 - NCT05943548Recruiting
Traditional healer support to help HIV reach low viral levels
This study tests whether support from traditional healers can help people with HIV get their viral load down to very low levels. You may be offered additional support and asked to attend clinic and nurse visits over 2 years.
MbararaAges 18 years+ - NCT06206564RecruitingPhase 2
Artesunate ointment for anal precancer in HIV-negative adults
This trial tests an artesunate ointment to treat high-grade anal precancer (HSIL) in people who do not have HIV. The goal is to see if the ointment can clear the abnormal cells caused by HPV.
Chicago, IllinoisAges 18 years+ - NCT06909110RecruitingPhase 1/Phase 2
Immune cells for viral infections after transplant
This trial tests a treatment using specially trained immune cells (virus-specific T-cells) to fight stubborn infections with adenovirus, CMV, or EBV in people with weakened immune systems, such as after a stem cell or organ transplant.
Palo Alto, CaliforniaAges 1 month–65 years - NCT06892015Recruiting
Oropouche virus shedding and immune response study
This study monitors how long the Oropouche virus stays in the body and how the immune system responds after a positive diagnosis. It may help us better understand the course of the infection and improve patient care.
Negrar, VRAges 18 years+ - NCT06027879Enrolling by invitationPhase 1/Phase 2
Anti-viral T-cell therapy for stubborn viral infections after transplant
This trial tests a treatment using specially grown T-cells (a type of immune cell) to fight certain viruses that won't go away with standard medicines. It is for people who have had a stem cell or organ transplant, or who have a weak immune system, and who are struggling with adenovirus, CMV, or EBV infections.
Pittsburgh, PennsylvaniaAges 1 month–65 years - NCT06886971Recruiting
Strategies to help youth with HIV stay virally suppressed
This trial tests a strategy to help young people with HIV keep their virus levels low. It focuses on using a long-acting injectable medication combination (Cabotegravir and Rilpivirine) and requires communication with your HIV doctor.
Baltimore, MarylandAges 12–30 - NCT06507059RecruitingPhase 3
Injectable HIV treatment trial for people with unsuppressed virus
This trial tests if switching to a long-acting injectable medication can help people with HIV who have trouble keeping their virus suppressed with daily pills. You would receive shots in the buttocks every few months instead of taking pills every day.
KeelungAges 18 years+ - NCT05866952Recruiting
Breathing and blood-flow testing in long-COVID symptoms
This trial studies how the lungs’ breathing (airflow) and blood flow may be off in people with long-COVID symptoms like tiredness, shortness of breath, or trouble exercising. It may help researchers understand what’s driving symptoms and what kinds of abnormalities could be targeted.
Boston, MassachusettsAges 18–99 - NCT05664126RecruitingPhase 2
Donor immune-cell treatment for stubborn CMV or adenovirus after transplant
This trial tests virus-fighting immune cells (T-cells) made from a donor to treat stubborn CMV or adenovirus infections after a blood and bone marrow transplant. It may help clear the virus when standard antiviral medicines are not working.
Memphis, TennesseeAges Up to 18 years - NCT05534425Enrolling by invitation
Study of a community mentoring program to boost antiviral defenses
This study tests whether a community-based, intergenerational mentoring program can help the body’s natural defenses against viruses. You may be able to join if you’re part of the GenX program and meet the basic location and screening requirements.
Los Angeles, CaliforniaAges 50 years+ - NCT06267508Recruiting
HIV testing and treatment for newborns
This study looks at ways to test and treat newborns for HIV early to improve their long-term health. It is for mothers with HIV whose babies are less than 3 days old and who are willing to have their babies tested and followed at home.
BeiraAges 18 years+ - NCT05564598RecruitingPhase 2
Trial of immune therapy for newborns with congenital CMV
This Phase 2 trial tests an immune treatment made from donor T-cells to help the body fight congenital CMV infection in newborns. It may be an option if your baby is very young, has evidence of CMV infection, and meets specific blood, kidney, and liver safety limits.
Los Angeles, CaliforniaAges birth–3 weeks - NCT06070688Recruiting
A test to tell if your breathing infection is bacterial or viral
This study tests a new way to quickly figure out if a respiratory infection is caused by bacteria or a virus. Knowing this could help doctors choose the right treatment faster and avoid unnecessary antibiotics.
Houston, TexasAges 18 years+ - NCT05918510Recruiting
Blood and tumor study for virus markers in throat cancer
This study looks at virus-related markers and tiny gene regulators (microRNAs) in tumor tissue from people with certain throat cancers caused by human papilloma virus (HPV). It’s observational, meaning it does not change your treatment, but results may help doctors better understand these cancers and how they behave.
RomeAges 18 years+ - NCT04098744RecruitingPhase 2
Artesunate vaginal inserts for high-grade cervical changes
This Phase 2 study tests whether artesunate vaginal inserts can help treat high-grade abnormal cells on the cervix (CIN2/3). It’s meant for adults who have a confirmed high-grade precancer change and can use birth control during the study.
Fort Myers, FloridaAges 25–100 - NCT05361603Recruiting
Screening for hepatitis B, C, and HIV at the same time
This trial tests how acceptable it is for people who use services outside traditional clinics to be screened for hepatitis B, hepatitis C, and HIV during the same visit. If you join, you would be asked to participate and provide consent for the screening process.
Limoges, Haute VienneAges 18 years+ - NCT06676410RecruitingPhase 2
Testing Codivir plus standard HIV treatment in new patients
This trial tests a new investigational drug called Codivir added to standard HIV treatment for people who have never taken HIV medications before. It aims to see if adding Codivir helps control the virus better and is safe.
São PauloAges 18 years+ - NCT06075264RecruitingPhase 2
Artesunate ointment for high-grade vulvar lesions

Rare disease registry and history study
This study keeps a registry (a structured list) of people with rare diseases and may also track how the condition changes over time. It can help researchers better understand rare illnesses and find gaps in care, which may improve future treatments.

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.
