Allergy clinical trials in California
We’re tracking 38 recruiting allergy studies with a site in California — including Phase 1, Phase 2 and Phase 3 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT03949855RecruitingPhase 2
Belimumab plus rituximab for primary membranous nephropathy
This study tests whether adding belimumab to rituximab helps people with primary membranous nephropathy (a kidney disease) that has the right blood test marker and specific protein levels. The goal is to improve kidney outcomes and reduce disease activity while keeping treatment safe.
San Francisco, CaliforniaAges 18–75 - NCT04047628RecruitingPhase 3
MS patients with active relapsing disease comparing two treatment plans
This Phase 3 study compares the best standard MS treatment (chosen by your doctors) versus an approach called autologous hematopoietic stem cell transplant (AHSCT) for people with highly active, treatment-resistant relapsing multiple sclerosis. It aims to see which option controls MS disease activity better and keeps you safer over time.
Palo Alto, CaliforniaAges 18–55 - NCT05201469RecruitingPhase 2
VIB4920 for lupus kidney inflammation not responding well enough
This Phase 2 study tests VIB4920 to treat active lupus nephritis, a type of kidney disease caused by lupus. It may help reduce kidney inflammation and improve kidney outcomes in people with active disease despite standard care.
Orange, CaliforniaAges 18 years+ - NCT05947071RecruitingPhase 2
Higher-dose flu vaccine versus standard dose in child transplant patients
This trial compares a higher-dose flu vaccine to the standard dose in children who recently received a kidney, heart, and/or liver transplant. It aims to see which dose better protects children against influenza while checking for safety.
Stanford, CaliforniaAges 3–17 - NCT06665646RecruitingPhase 1
HIV vaccine booster study for previous trial participants
This study tests a booster vaccine for HIV in people who were part of an earlier HIV vaccine trial. The goal is to see if it's safe and helps the immune system fight HIV better.
San Francisco, CaliforniaAges 18–60 - NCT06796686RecruitingPhase 1
HIV vaccine safety and immune response study for healthy adults
This trial tests a new two-part HIV vaccine regimen in healthy adults without HIV. The goal is to see if it is safe and produces an immune response that could help prevent HIV.
San Francisco, CaliforniaAges 18–55 - NCT06919003RecruitingPhase 2
Improving kidney transplant with a single injection of a protective protein
This trial tests whether a single injection of C1 esterase inhibitor into a donated kidney during preservation can improve transplant outcomes. It is for adults on dialysis waiting for a deceased-donor kidney who meet specific blood and tissue matching requirements.
Los Angeles, CaliforniaAges 18–75 - NCT07059091RecruitingPhase 2
Omalizumab for COPD with allergies
This trial tests if omalizumab, an allergy medication, can help people with COPD who have allergies to common indoor triggers like cat, dog, mouse, cockroach, or dust mite. It aims to reduce flare-ups and improve breathing.
San Francisco, CaliforniaAges 40 years+ - NCT06504160RecruitingPhase 1
Testing a bacteria cream for eczema (TIME-2)
This study tests whether a cream made from a friendly skin bacteria (Staphylococcus hominis) can help treat eczema. Eligible participants will apply the cream to eczema patches on their arms, legs, or trunk for several weeks.
San Diego, CaliforniaAges 6 years+ - NCT07321522Recruiting
Early feeding of allergenic foods in infants
This study tests whether introducing common allergenic foods early and continuing them for six months can help prevent food allergies in infants. It is for babies who have not yet started these foods.
Stanford, CaliforniaAges 4 months–11 months - NCT02734277Recruiting
Extending a past Type 1 diabetes immune study
This study is for people who already took part in an earlier immune-tolerance program for Type 1 diabetes. It tests whether continuing follow-up and assessments can be done safely and may help learn more about long-term immune effects of treatment.
San Francisco, CaliforniaAges 8–35 - NCT01186913Enrolling by invitation
Natural history study for severe combined immune deficiency (SCID)
This study follows children and adults with SCID and related immune disorders to understand how the illness behaves over time. It also helps researchers learn which testing results and genetic types of SCID match different treatment plans.
San Francisco, CaliforniaAges Any age - NCT07549503RecruitingPhase 2
Liver Transplant Immune Changes Study
This research study tracks early signs of immune system changes in children who received a liver transplant 3–7 years ago and are doing well. By studying blood and liver samples, researchers hope to better understand how to prevent rejection and improve long-term transplant survival.
San Francisco, CaliforniaAges 3–13 - NCT06583395Enrolling by invitation
Meditation retreat study with fitness tracker
This trial studies people attending a 7-day meditation retreat to see how meditation affects well-being. You will wear a fitness tracker and answer surveys.
Palm Desert, CaliforniaAges 21 years+

What taking part in a allergy 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 allergy clinical trials in California?
- Yes. We're currently tracking 38 recruiting allergy 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 allergy 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 allergy 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 allergy 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.
