Lancaster, CaliforniaAges 13 years+ - NCT07108660Recruiting
Predicting and reducing bloodstream infections from central lines
This trial uses machine learning to predict infections that can happen with central lines (special IVs placed in large veins) and aims to reduce how often they occur. It focuses on hospitals with the highest infection rates, so you might be eligible if you receive care at one of these hospitals.
Orange, CaliforniaAges 18 years+ - NCT07221370RecruitingPhase 2/Phase 3
Vancomycin to prevent C. diff infection in ICU patients
This trial tests whether giving vancomycin through a tube into the stomach can prevent a serious gut infection called C. diff in people who are very sick in the ICU and taking antibiotics. If you qualify, you might receive this medicine to lower your risk.
Moreno Valley, CaliforniaAges 18 years+ - NCT04665037RecruitingPhase 2
Posaconazole study for infants under 2 with serious fungal infection
This trial tests whether posaconazole, given through a vein or by mouth, can treat invasive fungal infections in children under 2 years old. It may help improve outcomes for infants with hard-to-treat fungal disease.
San Diego, CaliforniaAges 1 day–2 years - NCT07513285RecruitingPhase 2
Ibezapolstat pill for recurrent C. difficile infection
This trial tests a new oral antibiotic called ibezapolstat to treat recurrent C. difficile infection (CDI)—a serious diarrheal illness caused by bacteria in your gut. The study focuses on patients who have had multiple CDI episodes and may benefit from a different treatment approach.
Sacramento, CaliforniaAges 18–90 - NCT07387367RecruitingPhase 3
Comparing two drugs for adenovirus after stem cell transplant
This trial tests a new drug, brincidofovir (BCV), against an existing drug, cidofovir (CDV), for treating adenovirus infection in people who recently had a stem cell transplant. The goal is to see which works better with fewer side effects.
Duarte, CaliforniaAges 2 months+ - NCT05592626RecruitingPhase 1/Phase 2
T cell activator STAR0602 for advanced solid tumors
This study tests an experimental drug called STAR0602 that aims to boost your immune system's T cells to fight advanced solid tumors. It's for patients whose cancer has not responded to standard treatments or for whom such treatments are not suitable.
Sacramento, CaliforniaAges 18 years+ - NCT05369052RecruitingPhase 3
New antibiotic for moderate or severe diabetic foot infections
This Phase 3 trial tests a new medicine (contezolid acefosamil, and contezolid) to treat moderate or severe diabetic foot infections. It compares the new treatment to linezolid to see which works better and is safer for adults.
Corona, CaliforniaAges 18 years+ - NCT06794541RecruitingPhase 2
Testing eravacycline for kids with serious belly infections
This trial tests an antibiotic called eravacycline for children (ages 8–17) with serious belly infections. The medicine is given through an IV in the hospital to see if it is safe and tolerable.
Orange, CaliforniaAges 8–17 - NCT05143307Enrolling by invitationPhase 1
Follow-up study for adults who received EBT-101 for HIV
This study checks how adults are doing long-term after receiving an HIV treatment called EBT-101 in an earlier study. It helps researchers understand safety and longer-term effects over time.
San Francisco, CaliforniaAges 18 years+ - NCT06822426RecruitingPhase 3
Preventing infections in central lines for people on IV nutrition
This trial tests a new catheter lock solution (DefenCath) to prevent infections in people who need long-term IV nutrition through a central line. It compares the study drug to a standard heparin lock, and you'll be randomly assigned to one group.
Los Angeles, CaliforniaAges 18 years+ - NCT06801223RecruitingPhase 1
Testing sulbactam-durlobactam for children with ABC infection
This trial tests a new combination of antibiotics (sulbactam-durlobactam) for children with a serious infection caused by Acinetobacter bacteria. The goal is to see if this treatment is safe and works well for kids.
Los Angeles, CaliforniaAges 1 day–18 years - NCT05361941Recruiting
Antibiotic graft to help bone regrow in infected knee surgery areas
This trial tests an antibiotic “graft” placed into or near infected bone cavities around a knee replacement (TKA) to help new bone grow. You may be considered if you have an infected knee implant area and can safely take part in follow-up visits and treatment.
Los Angeles, CaliforniaAges 22 years+ - NCT06002607Recruiting
Shorter vs longer antibiotics for severe skin infections
This study compares a shorter course (about 7 days) of antibiotics to a longer course (about 14 days) for people who had surgery for a severe skin and muscle infection. The goal is to see if a shorter treatment works just as well.
Orange, CaliforniaAges 18 years+ - NCT05985642Recruiting

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.

Common questions
- Are there infections clinical trials in California?
- Yes. We're currently tracking 159 recruiting infections studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a infections study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a infections trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New infections studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
