ParisAges 18 years+ - NCT05814237Recruiting
Study of new respiratory infections starting within 10 days
This is an observational study that follows adults who are newly sick with a respiratory infection that started within the past 10 days. It may help researchers understand what causes these infections and how patients do in emergency or hospital-care settings.
BrusselsAges 18 years+ - NCT05947071RecruitingPhase 2
Higher-dose flu vaccine versus standard dose in child transplant patients
This trial compares a higher-dose flu vaccine to the standard dose in children who recently received a kidney, heart, and/or liver transplant. It aims to see which dose better protects children against influenza while checking for safety.
Stanford, CaliforniaAges 3–17 - NCT05972772RecruitingPhase 2/Phase 3
Test study drugs to clear rickettsia infections
This study tests antibiotics to help your body clear rickettsia-related illnesses like murine typhus or scrub typhus. It may help reduce symptoms and shorten how long you feel sick, based on how well the infection clears.
Vientiane, VientaineAges 18 years+ - NCT06004739Recruiting
Antibiotics for older adults with delirium and abnormal urine tests
This trial tests whether giving antibiotics helps older adults in the hospital who have delirium (sudden confusion) and signs of bacteria in their urine but no clear urinary infection. It aims to see if treatment can improve confusion and avoid unnecessary antibiotics.
Chicago, IllinoisAges 60 years+ - NCT06024421RecruitingPhase 1
Testing high doses of favipiravir in healthy volunteers
This study tests the safety and how the body processes very high doses of the antiviral drug favipiravir in healthy people. It helps find the highest dose that is still safe before testing in patients.
ParisAges 18–75 - NCT06034080Recruiting
Cutting down unneeded antibiotics for children's ear infections
This study tests ways to help doctors avoid prescribing antibiotics when they are not needed for children with ear infections. If you are a parent of a child diagnosed with an ear infection or a healthcare provider, you may be able to join different parts of the study.
Denver, ColoradoAges 6 months–17 years - NCT06056102RecruitingPhase 1
CAR-T cell therapy to help highly sensitized kidney transplant patients
This trial tests whether a special immune cell treatment (CAR-T cells) can lower the antibodies that make it very hard for you to receive a kidney transplant. If it works, you might become eligible for a transplant sooner.
Boston, MassachusettsAges 18–65 - NCT06096857RecruitingPhase 2
Cardamom and topical bacteria cream for eczema
This study tests whether taking cardamom by mouth and applying a cream made from a harmless bacteria (Roseomonas) can help treat eczema (atopic dermatitis) in people age 2 and older.

Common questions
- Are there clinical trials for infectious disease?
- Yes. Clin2 currently lists 254 recruiting infectious disease 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 infectious disease 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 infectious disease 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.
