Viral Infection clinical trials in California
We’re tracking 14 recruiting viral infection studies with a site in California — including Phase 1/Phase 2, Phase 2 and Phase 3 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT07110636Recruiting
Blood test for infection in immunocompromised adults
This trial tests a blood test that looks for infection by analyzing tiny bits of DNA from microbes. It may help find infections faster in people with weakened immune systems, such as transplant recipients or those with blood cancers.
San Francisco, CaliforniaAges 18 years+ - NCT05123755RecruitingPhase 2
Testing a new medicine in hospitalized pneumonia patients needing oxygen
This Phase 2 trial tests an investigational medicine (given in increasing doses) for hospitalized people with pneumonia who need supplemental oxygen. It aims to see if the medicine is safe and potentially helps the pneumonia process in the early hospital period.
Newport Beach, CaliforniaAges 18 years+ - NCT05624450RecruitingPhase 3
Test drug tozorakimab for hospitalized viral lung infection needing oxygen
This Phase 3 study tests tozorakimab to see if it helps people hospitalized with a viral lung infection that is causing low oxygen levels. You might qualify if you still need supplemental oxygen when the study starts.
Chula Vista, CaliforniaAges 18 years+ - NCT05603650Recruiting
Mouthwash study for healthy bacteria in your mouth and gut
This study tests how a mouthrinse changes the helpful bacteria in your mouth and stomach/gut. You may need several visits and phone follow-ups to see how your microbiome shifts over time.
Irvine, CaliforniaAges 18 years+ - 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+ - NCT04197596RecruitingPhase 1/Phase 2
BK infection immune-cell treatment after transplant or weak immunity
This Phase 1/2 study tests lab-made immune cells that specifically target BK virus in people whose BK infection keeps coming back or doesn’t improve. It may help by boosting the body’s ability to clear the virus, especially when standard antiviral treatments don’t work or can’t be tolerated.
San Francisco, CaliforniaAges 1 month–79 years - 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+ - 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 - NCT06370780Recruiting
Smartphone app to help with HIV viral suppression
This study uses a smartphone app to help people with HIV who have trouble staying virally suppressed stay healthy. It’s for those who are not currently suppressed, not in care, or at risk of becoming unsuppressed.
Los Angeles, CaliforniaAges 18 years+ - NCT06788093Recruiting
Reducing antibiotic overuse with decision support
This trial tests a tool to help doctors decide when antibiotics are truly needed for lung infections like bronchitis or pneumonia. It may help you avoid unnecessary antibiotics and their side effects.
San Francisco, CaliforniaAges 6 months–17 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 - NCT06909110RecruitingPhase 1/Phase 2
Immune cells for viral infections after transplant
This trial tests a treatment using specially trained immune cells (virus-specific T-cells) to fight stubborn infections with adenovirus, CMV, or EBV in people with weakened immune systems, such as after a stem cell or organ transplant.
Palo Alto, CaliforniaAges 1 month–65 years - 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.
Los Angeles, CaliforniaAges 50 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

What taking part in a viral infection 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.
Viral Infection trials in other states
Common questions
- Are there viral infection clinical trials in California?
- Yes. We're currently tracking 14 recruiting viral infection 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 viral infection 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 viral infection 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 viral infection 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.
