We’re tracking 159 recruiting infections studies with a site in California — including Phase 1, Phase 1/Phase 2 and Phase 2 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT06963710RecruitingPhase 2
New Hepatitis B Treatment vs Standard Drug
This trial tests a new oral medication (ALG-000184) compared to an existing drug (tenofovir) for people with chronic hepatitis B who have not been treated recently. It aims to see if the new drug is better at lowering the virus and improving liver health.
Coronado, CaliforniaAges 18–65 - NCT06999603RecruitingPhase 2
Inhaled study drug for virus infections on ventilators
This study tests an inhaled study drug (SNG001) for adults on a breathing machine in the ICU due to a viral lung infection. The goal is to see if the drug can help patients recover faster.
Sacramento, CaliforniaAges 18 years+ - NCT07147517Recruiting
Tracking respiratory viruses in your community and home
This study tracks how respiratory viruses spread in the community and within households. It involves testing and collecting samples from people who are sick or healthy, to help better understand and prevent outbreaks.
San Ysidro, CaliforniaAges Any age - NCT07221097Recruiting
Testing a new panel to detect COVID-19 and other coronaviruses
This trial uses leftover nasal swab samples to test a new panel that can detect COVID-19 and other coronaviruses. It helps see if the panel works well for diagnosing these infections.
Los Angeles, CaliforniaAges Any age - NCT07227441Recruiting
Chronic Infections and Inflammation in ME/CFS
This study looks at how chronic infections and inflammation affect people with ME/CFS (myalgic encephalomyelitis/chronic fatigue syndrome) compared to healthy people. Researchers want to understand what causes symptoms and find better ways to help.
San Francisco, CaliforniaAges 18 years+ - NCT07300267RecruitingPhase 1
Study of a new pneumococcal vaccine for infants and toddlers
This trial tests a new vaccine called V118C to protect children against pneumococcal disease. It is for two age groups: toddlers aged 12-15 months who already had 3 doses of a standard pneumococcal vaccine, and babies about 2 months old who have not had any pneumococcal vaccine yet.
Madera, CaliforniaAges 2 months–1.3 years - 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.
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 - NCT07431840Recruiting
Immune protein for respiratory infections in older adults
This trial tests whether an immune defense protein can help reduce upper respiratory infections (like colds) in people aged 60 and older. It may be a good fit if you get colds or flu-like symptoms several times each season.
Los Angeles, CaliforniaAges 60 years+ - NCT07433985Recruiting
California mobile app study for men after jail release
This study tests a mobile app to help men recently released from jail or prison who use drugs or have sex with men stay healthy and avoid HIV. It's for people who don't have HIV and live in certain California counties.
Oakland, CaliforniaAges 18–59 - NCT05952804RecruitingPhase 2
IVIG to help prevent infections after CAR-T treatment
This Phase 2 study tests whether IVIG (a blood product that helps fight infections) can lower infection risk after you receive CD19 CAR-T therapy. It’s meant to help protect you during the vulnerable period after CAR-T treatment.
Duarte, CaliforniaAges 18 years+ - NCT07520279Enrolling by invitation
Rapid fever test for tropical diseases
This study tests a new rapid diagnostic tool that can quickly identify tropical fever-causing infections like malaria, dengue, Zika, chikungunya, or leptospirosis from a blood sample. The goal is to help doctors diagnose these infections faster so patients can get treatment sooner.
San Diego, CaliforniaAges 14 years+ - NCT06488846Enrolling by invitation
Giving HIV injections at home with a helper
This study tests whether having a trained friend or family member give you your HIV injections at home is safe and works as well as getting them at a clinic. You may qualify if you are already on the injectable HIV medication cabotegravir/rilpivirine (Cabenuva) and have a support person willing to help.
San Francisco, CaliforniaAges 18 years+ - NCT06257420Enrolling by invitation
Low-dose rapamycin for ME/CFS and Long-COVID
This trial tests whether a low dose of rapamycin, a drug that may help regulate the immune system, can improve symptoms in people with ME/CFS or Long-COVID.
Palo Alto, CaliforniaAges 18–65 - NCT05534425Enrolling by invitation
Study of a community mentoring program to boost antiviral defenses
This study tests whether a community-based, intergenerational mentoring program can help the body’s natural defenses against viruses. You may be able to join if you’re part of the GenX program and meet the basic location and screening requirements.

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.
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.
