Test mesh use for breast reconstruction above the muscle
This study tests whether using surgical mesh can be done safely and works well in breast reconstruction done right away, in front of the chest muscle (pre-pectoral) using tissue expanders. It may help improve how the reconstructed area holds up, but you’d need to meet specific surgical and health requirements.
Los Angeles, CaliforniaAges 22–75 - NCT05711667RecruitingPhase 3
Letermovir to prevent CMV after stem cell transplant in kids

Oakland, CaliforniaAges 2–18 - NCT07227441Recruiting
Chronic Infections and Inflammation in ME/CFS

San Francisco, CaliforniaAges 18 years+ - NCT07215273RecruitingPhase 2
Testing a new antifungal for mold infections in immunocompromised people
This study tests a new antifungal drug (EL219) compared to two standard treatments (liposomal amphotericin B or voriconazole) for people with weakened immune systems who have a suspected or confirmed mold infection. The goal is to see if the new drug works as well or better at treating the infection.

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 156 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.
