This trial tests a cocktail of viruses (bacteriophages) that target achromobacter bacteria in the lungs of adults with cystic fibrosis. It aims to see if the phages are safe and can reduce the infection.
San Diego, CaliforniaAges 18 years+ - NCT03266653RecruitingPhase 2
T-cell therapy for stubborn Epstein-Barr virus after transplants
This trial tests an immune therapy made from EBV-targeted T-cells to treat EBV infections that do not improve with standard anti-viral medicines. It may help by strengthening the body’s ability to fight EBV after certain transplants or immune problems.
Los Angeles, CaliforniaAges 1 month–79 years - NCT03808922RecruitingPhase 3
DAS181 treatment for COVID-19 lung infection in immune-compromised adults
This Phase 3 trial tests DAS181 to treat lower lung (chest) viral infections in people with weakened immune systems, including a COVID-19 subgroup. It may help by targeting certain viruses in the lungs, but joining depends on your oxygen needs, recent diagnosis, and other safety factors.
Duarte, CaliforniaAges Any age - NCT03827694Recruiting
Testing a noninvasive scan for serious lung mold infections in kids
This study uses noninvasive breathing/relates imaging (MRI or CT) to help diagnose mold infections in the lungs in children and young adults. It may help doctors find these infections sooner, especially in people with weakened immune systems.
San Francisco, CaliforniaAges 4 months–21 years - NCT07285213RecruitingPhase 2
Preventing C. diff return with an antibody
This study tests a new antibody (AZD5148) to prevent C. diff infection from coming back. If you have a current C. diff infection and are being treated with antibiotics, you may be able to join.
Chula Vista, CaliforniaAges 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 - NCT04648046RecruitingPhase 1/Phase 2
CAR-T cell treatment for HIV infection
This early-phase study tests whether CAR-T cells (immune cells modified to recognize HIV) can help control HIV. You may be asked to briefly pause HIV medicines to see how well the treatment controls the virus.
Sacramento, CaliforniaAges 18–65 - NCT04705766Recruiting
Study kidney injury after recent COVID infection
This study looks at how COVID can affect the kidneys soon after infection. You may be able to participate if you recently tested positive for COVID and have not had kidney replacement treatments.
San Francisco, CaliforniaAges 18 years+ - NCT04812093Recruiting
Tests a way to evaluate middle ear infection
This study looks at a test method to check middle ear infections in people who are planning surgery. It may help clinicians better evaluate the infection before or during treatment.
Orange, CaliforniaAges Up to 21 years - 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+ - NCT05219110Recruiting
More fluids for children sick with toxin E. coli
This study looks at whether giving extra (hyper) fluids early helps children with a high-risk E. coli stomach infection. The goal is to improve outcomes by supporting the kidneys during the illness.

What taking part in a infections study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
