We’re tracking 94 recruiting chronic disease studies with a site in California — including Phase 1, Phase 1/Phase 2, Phase 2 and Phase 3 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT06883305RecruitingPhase 3
Testing tezepelumab for moderate to severe COPD
This trial tests tezepelumab, an injected medication, for people with moderate to very severe COPD who still have flare-ups despite using standard inhalers. It may help reduce flare-ups and improve breathing for those with higher eosinophil levels.
Newport Beach, CaliforniaAges 40–80 - 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+ - NCT04613921Recruiting
Liver transplant study for severe worsening liver failure
This study looks at when liver transplant is offered and what outcomes happen in people with cirrhosis who have severe “acute-on-chronic” worsening. It may help doctors decide which patients benefit most from transplant and improve care after listing or not listing.
Los Angeles, CaliforniaAges 18–80 - NCT01804686RecruitingPhase 3
Long-term ibrutinib follow-up with or without nivolumab
This study looks at how safe and effective ibrutinib is over the long term, either alone or together with nivolumab. You may join if you are already in an earlier ibrutinib study and your care team feels staying on ibrutinib is worth the risk.
Duarte, CaliforniaAges 18 years+ - NCT07025538RecruitingPhase 1
Preventing chronic graft-versus-host disease with ruxolitinib
This trial tests whether the drug ruxolitinib, given based on a blood test that predicts risk, can prevent chronic graft-versus-host disease (cGVHD) after a stem cell transplant. It may help people who have a higher risk of developing this complication.
Duarte, CaliforniaAges 18 years+ - NCT05021029Enrolling by invitation
Study of stomach changes that can turn cancerous
This study follows people with stomach conditions that can sometimes develop into cancer. It may help researchers better understand these changes and guide care, especially for people who need an endoscopy (a look inside the stomach).
Sacramento, CaliforniaAges 18 years+ - NCT04684602RecruitingPhase 1/Phase 2
Study of stem cells for several short- and long-term illnesses
This early-stage study tests whether injections of mesenchymal stem cells can be safe and helpful for certain chronic (long-term) and acute (short-term) conditions. You might be considered if you can consent, are able to return for follow-up visits, and do not have key reasons that would make stem-cell treatment unsafe.
Culver City, CaliforniaAges 18 years+ - NCT07091019Recruiting
CML patient experience study on standard TKI therapy
This study tracks the experiences and health outcomes of people with chronic myeloid leukemia (CML) who are taking approved first or second line tyrosine kinase inhibitor (TKI) medicines. It helps doctors learn how these treatments work in everyday care.
Stockton, CaliforniaAges 18–100 - NCT03779854RecruitingPhase 2
Preventing graft-versus-host disease in kids after stem cell transplant
This trial tests whether removing certain immune cells (T cells) from the donor transplant can lower the risk of chronic graft-versus-host disease (long-term immune attack after transplant) in children and young adults with blood cancers. If you qualify, it may help improve transplant outcomes while tracking safety and side effects.
Los Angeles, CaliforniaAges 6 months–26 years - NCT05919511Recruiting
Questionnaire study for people at risk after stem cell transplant
This observational study follows people who had a stem cell transplant a few months ago to better understand risk for chronic graft-versus-host disease. You won’t get a study treatment; instead, you’ll complete questionnaires over time, and the study team looks at your symptoms and experiences.
Duarte, CaliforniaAges 18 years+ - NCT06217302RecruitingPhase 3
Sotagliflozin for kidney protection in type 1 diabetes
This study tests whether sotagliflozin (a pill that helps control blood sugar and protects the kidneys) can slow down kidney function decline in people with type 1 diabetes and diabetic kidney disease. You may qualify if you have had type 1 diabetes for at least 8 years, have moderate kidney damage, and are on standard treatments.
Stanford, CaliforniaAges 18–75 - NCT07235501Recruiting
Studying immune cells in chronic GVHD after stem cell transplant
This study looks at immune cells in the blood and tissues of people who have had a stem cell transplant. It aims to understand chronic graft-versus-host disease (GVHD), a common complication, so doctors can better detect and treat it.
Duarte, CaliforniaAges 7 years+ - NCT06815003RecruitingPhase 2
Preventing Graft-Versus-Host Disease After Stem Cell Transplant
This trial tests a combination of three drugs (vedolizumab, cyclophosphamide, and tacrolimus) to prevent graft-versus-host disease, a common complication after a donor stem cell transplant. It is for people with certain blood cancers who are getting a reduced-intensity transplant.
Duarte, CaliforniaAges 18–80 - NCT05313165Recruiting
Stent procedure for poor blood flow in the leg ulcers and gangrene
This trial tests a new minimally invasive procedure (placing a small stent) to improve blood flow to a severely threatened foot or lower leg. It may help people whose ulcers or gangrene are not treatable with standard bypass or other surgeries.
Palo Alto, CaliforniaAges 18–95 - NCT06016257Recruiting
Virtual home exercise program for shoulder rehab
This study tests a virtual home exercise program (VirtuaCare) for people with shoulder problems who need physical therapy. It aims to see if doing exercises at home with virtual guidance works as well as standard care.
Los Angeles, CaliforniaAges 18 years+ - NCT01351545Recruiting
Cryopreserved cord blood access program for transplant patients
This trial studies an organized way to obtain and distribute unlicensed (not FDA-approved for general use) stored cord blood units that have been frozen and kept. It may help people who need a cord blood transplant but don’t fit the “licensed cord blood only” options.
Loma Linda, CaliforniaAges Any age - NCT05181826Recruiting
Blood collection study for cancer and benign diseases
This study collects blood samples from people with different health conditions (cancer, diabetes, liver disease, etc.) and from healthy volunteers. The goal is to find markers in the blood that could help detect or monitor diseases.
Redondo Beach, CaliforniaAges 18 years+ - NCT06810505RecruitingPhase 3
Oral atogepant for preventing migraines in teens
This trial tests an oral medication called atogepant to see if it can prevent migraines in teens aged 12–17. It aims to reduce how often migraines happen and track any side effects.
Anaheim, CaliforniaAges 12–17 - NCT04895436RecruitingPhase 2
Oral venetoclax plus IV obinutuzumab after prior CLL treatment
This trial tests whether adding oral venetoclax together with an IV antibody called obinutuzumab can control CLL when the disease comes back after a specific prior treatment. It also looks closely at side effects to see what changes in “disease activity” and safety to expect.
La Jolla, CaliforniaAges 18 years+ - NCT06970977Recruiting
Chronic sinusitis questionnaire validation study
This study is testing a new questionnaire to better understand chronic sinusitis symptoms. It may help improve how doctors diagnose and treat the condition.
Santa Monica, CaliforniaAges 18 years+ - NCT06476132RecruitingPhase 2
Belumosudil for lung transplant patients at risk of chronic rejection
This trial tests whether the drug Belumosudil can help prevent chronic lung rejection in people who recently had a lung transplant and showed signs of early rejection. It may improve long-term lung health.
Los Angeles, CaliforniaAges 12 years+ - NCT06859424RecruitingPhase 2
Testing a new GVHD prevention method after donor stem cell transplant
This trial tests a new way to prevent graft-versus-host disease (a common side effect of stem cell transplant) using a drug called cyclophosphamide after transplant. It is for adults with certain blood cancers who need a transplant from a partially matched unrelated donor.

What taking part in a chronic disease 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 chronic disease clinical trials in California?
- Yes. We're currently tracking 94 recruiting chronic disease 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 chronic disease 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 chronic disease 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 chronic disease 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.
