Recruiting studies in California
- 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.
Redwood City, CaliforniaAges 18–64 - NCT03174977RecruitingEarly Phase 1
How HIV medicine moves through the body on MRI scans
This early study measures how raltegravir (an HIV medicine) spreads in the body using a special scan called PET/MR. It may help doctors better understand how to deliver and monitor HIV treatment, even though it focuses on measuring drug behavior rather than curing HIV.
San Francisco, CaliforniaAges 18 years+ - NCT05564598RecruitingPhase 2
Trial of immune therapy for newborns with congenital CMV
This Phase 2 trial tests an immune treatment made from donor T-cells to help the body fight congenital CMV infection in newborns. It may be an option if your baby is very young, has evidence of CMV infection, and meets specific blood, kidney, and liver safety limits.
Los Angeles, CaliforniaAges birth–3 weeks - NCT03346694Recruiting
Testing a new chest dressing to prevent wound infections
This trial looks at whether a different dressing placed on the chest incision during certain heart surgeries can lower the risk of surgical wound infections. If you are having a sternotomy (a cut through the breastbone), this could help keep your incision cleaner while you heal.
Stanford, CaliforniaAges 18 years+ - 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+ - NCT06071767RecruitingPhase 1/Phase 2
Immune therapy trial for early-treated HIV
This study tests whether a combination of three immune therapies can help control HIV without daily medication. You may qualify if you started HIV treatment very early and have had a suppressed viral load for at least a year.
San Diego, CaliforniaAges 18 years+ - NCT06010433Recruiting
CERAMENT G treatment tracking study
This study tracks how well the CERAMENT G device works for people getting it as part of their treatment. It helps doctors gather real-world safety and effectiveness information.
San Diego, CaliforniaAges 18 years+ - NCT07181486RecruitingPhase 1
Safety study of a vaginal gel for healthy women

San Francisco, CaliforniaAges 18–45 - 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.
Sacramento, CaliforniaAges 18 years+ - NCT06631365RecruitingPhase 2
PrEP on demand: a pilot study for men who have sex with men
This study tests a '2-1-1' on-demand PrEP strategy for cisgender men who have sex with men. It aims to see if taking PrEP only around the time of sex is safe and effective. If you are interested in starting or currently taking PrEP this way, you may be eligible.
San Francisco, CaliforniaAges 18 years+ - NCT05653232Recruiting
Preventing hepatitis C in kidney transplant recipients using antiviral pills
This study tests antiviral medicine given around the time of a kidney transplant to prevent hepatitis C infection when the donor has hepatitis C. It may help uninfected recipients stay hepatitis C–free after receiving the kidney.
Loma Linda, CaliforniaAges 18 years+ - NCT07293559Recruiting
Understanding infant feeding choices in women with HIV
This study looks at how women with HIV decide whether to breastfeed, and what support they get from healthcare providers and family. It aims to learn about their experiences and needs.
Los Angeles, CaliforniaAges Any age - NCT07211997Recruiting
FebriDx test for fever and cold symptoms in children
This study tests a finger-prick blood test (FebriDx) to see if it can quickly tell whether a child's fever and cold symptoms are caused by a bacterial or viral infection. If it works, it could help doctors decide whether antibiotics are needed.
Colton, CaliforniaAges 2–11 - NCT02889016Recruiting
Markers study for children with PANS and healthy controls
This study looks at physical, immune, and brain-related “markers” in children with PANS and compares them with healthy children. It may help doctors understand what is happening in PANS and how to recognize it more clearly early on.
Palo Alto, CaliforniaAges 4–18 - NCT07125235Recruiting
Support program for HIV treatment adherence
This trial tests a program to help people with HIV stay on track with their medication. If you take HIV medication, sometimes miss doses, and use stimulants, this program may offer support to improve your health.
San Francisco, CaliforniaAges 18–70 - NCT05655182RecruitingPhase 1/Phase 2
RSV vaccine study for infants and toddlers who may be at risk
This Phase 1/2 study tests an RSV vaccine (BLB-201) in infants and young children. It aims to see how the vaccine works and how safe it is, including in children who already have RSV antibodies or not.
La Mesa, CaliforniaAges 6 months–5 years - NCT07202546RecruitingPhase 2
New oral HIV drug trial for people new to treatment
This trial tests a new oral HIV medication (VH4524184) in people who have never taken HIV treatment before. It looks at how well the drug controls the virus and how safe it is.
Bakersfield, CaliforniaAges 18 years+ - NCT07473778Recruiting
Study of Lenacapavir for HIV Prevention
This trial tests a new medication, lenacapavir, to see how well it works for preventing HIV. It is for people who want or need PrEP (a medicine to prevent HIV) and are interested in learning about different options.
Beverly Hills, CaliforniaAges 18 years+ - NCT07069400Recruiting
Observational study of adults with acute infection
This study observes adults hospitalized with a new or recent infection (symptoms started within 30 days). The goal is to learn more about how infections affect people in the hospital, without testing any new drugs or treatments.
Palo Alto, CaliforniaAges 18 years+ - NCT07022678RecruitingPhase 3
Xylitol dental wipes to reduce infection risk in childhood leukemia
This trial tests whether using xylitol dental wipes can lower the risk of bloodstream infections in children with acute myeloid leukemia (AML) who are receiving chemotherapy. If you or your child have AML and will have at least two cycles of chemo that include cytarabine, this study may help reduce infection risk.
Madera, CaliforniaAges 1–25 - NCT05243966Recruiting
Registry for soft tissue repair using a special matrix
This study is a registry that collects information from people who had soft tissue repair using a specific matrix and/or morcell material. It may help researchers understand how this approach performs in real-world care and patient outcomes over time.
Los Angeles, CaliforniaAges 18 years+ - NCT03266640RecruitingPhase 2
CMV cell therapy for difficult-to-treat viral infection
This trial tests an immune cell treatment (CMV-specific cytotoxic T cells) for people with a CMV infection that is not improving despite standard antivirals, or who cannot tolerate them. If eligible, the treatment aims to help the body control the virus after transplant-related immune problems.
Los Angeles, CaliforniaAges 1 month–79 years - NCT03266627RecruitingPhase 2
Adenovirus T-cell therapy for hard-to-treat virus after transplants

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 160 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?
