We’re tracking 156 recruiting infections studies with a site in California — including Early Phase 1, Phase 1/Phase 2, Phase 2, Phase 3 and Phase 4 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT04949464Recruiting
Smoking quit coaching plus lung scans for people with HIV
This study tests a behavior-change program to help people with HIV quit smoking, along with routine low-dose lung CT scans to find warning signs early. It’s a feasibility study, meaning the main goal is to see if the approach is practical and acceptable, and if people can follow through.
La Jolla, CaliforniaAges 45–80 - NCT04883255RecruitingEarly Phase 1
Study cannabis effects on brain function in adults with HIV
This early-phase study looks at how cannabis (and the body’s cannabinoid system) may affect thinking and brain-related measures in people with HIV. You may be asked to avoid cannabis and complete several brain and health assessments to see how these factors relate.
San Diego, CaliforniaAges 18–65 - NCT04815096RecruitingPhase 2
PET scan study of immune activity after COVID-19
This Phase 2 study uses a special PET scan to look at how active your immune system is after a recent COVID-19 infection. The goal is to understand what the immune response looks like and whether this imaging approach could help guide care.
San Francisco, CaliforniaAges 18 years+ - NCT04821154Recruiting
Testing outcomes after revision knee replacement with a Persona system
This study looks at how well a specific revision knee replacement system (the Persona system) works after earlier knee problems or surgeries. You may be eligible if you need a revision knee and can follow follow-up care instructions; the trial also checks for certain infection, bone, and health-safety factors.
Fresno, CaliforniaAges 18 years+ - NCT04678154RecruitingPhase 3
Antibiotic trial for severe open fractures of the leg or foot
This trial tests a new way of giving antibiotics to people with severe open fractures in the leg, ankle, or foot. The goal is to see if it helps prevent infections after surgery.
San Francisco, CaliforniaAges 18–64 - NCT04579588Recruiting
Study flu vaccine immunity in people after COVID-19
This study looks at how well your immune system (your body’s infection-fighting system) responds to a flu vaccine after you’ve had COVID-19. It may help doctors understand why some people have different protection after vaccines.
Palo Alto, CaliforniaAges 9–64 - NCT04362150Recruiting
Study of long-term effects after COVID-19 infection
This study follows adults who had COVID-19 to learn how the illness can affect health over the long term. It may help researchers understand lasting symptoms and who is at higher risk, which could improve future care.
San Francisco, CaliforniaAges 18–100 - NCT03325855Recruiting
Fecal transplant registry for patients and donors
This study is a national “registry” that collects information from people who get fecal microbiota transplant (a stool-based treatment) and from people who donate stool. It helps researchers understand who receives these treatments and how they do over time.
Ventura, CaliforniaAges Any age - NCT03713528Enrolling by invitationPhase 4
Antibiotic placed in bone to help save an infected knee implant
This trial tests whether putting antibiotics directly inside the bone during surgery can improve outcomes for an infected knee prosthesis when the implant is being kept. It may help more people avoid needing full implant removal and replacement.
San Francisco, CaliforniaAges 18 years+ - NCT03354728RecruitingPhase 1/Phase 2
Vaccine trial for children with CMV after stem cell transplant
This trial studies a vaccine designed to help the body fight cytomegalovirus (CMV) in children who test positive for CMV and are about to receive a donor stem cell transplant. If it works, it may reduce CMV-related illness during recovery after transplant.
Duarte, CaliforniaAges 1–21 - NCT02140255RecruitingPhase 1/Phase 2
Intensive early HIV treatment in newborns to aim for remission
This study gives very early, intensive HIV medicine to infants diagnosed with HIV and follows them closely to see if HIV can go into remission (stop being detectable without ongoing treatment). It may help families understand whether treating right after birth can change a child’s long-term HIV outlook.
La Jolla, CaliforniaAges Up to 2 days - NCT00187512Recruiting
Study of how HIV treatment changes outcomes over time
This is an observational study (not a new drug) that tracks how living with HIV can change over time in different treatment situations. It may help researchers understand long-term effects of the modern “protease inhibitor era” and improve future care.

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.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
