Recruiting studies in California
- 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+ - NCT06559176Enrolling by invitationPhase 1/Phase 2
Gene editing trial for chronic granulomatous disease
This trial tests a new gene editing treatment called PM359 for people with a specific type of chronic granulomatous disease (CGD) caused by a delGT mutation in the NCF1 gene. The goal is to see if it's safe and helps fight infections and inflammation.
Los Angeles, CaliforniaAges 6 years+ - NCT05843500Recruiting
CTEPD and CTEPH registry for long-term blood-clot lung disease
This study builds a registry to learn about people with chronic blood-clot lung disease (CTEPD/CTEPH) and what symptoms and test results look like over time. It may help clinicians better understand the condition and improve future care, since your participation supports data collection rather than a new drug.
San Francisco, CaliforniaAges 18 years+ - NCT05744713Enrolling by invitation
Study of adults with long-term liver disease using health records
This observational study looks at adults with chronic liver disease (including cirrhosis) to better understand how people are managed and how they feel over time. Because it does not change your treatment, it may help researchers improve care and patient support.
Los Angeles, CaliforniaAges 18 years+ - NCT06605378Recruiting
Antibody and cytokine study for people with CGD
This study is checking levels of antibodies and immune-signaling molecules (cytokines) in people with chronic granulomatous disease (CGD). It aims to better understand the immune system in CGD, which may help with future treatments.
Sacramento, CaliforniaAges Any age - NCT06717698RecruitingPhase 2
Testing a new medicine for kidney damage in chronic kidney disease
This study tests different doses of an investigational medicine (NNC0519-0130) to see if it can reduce kidney damage in people with chronic kidney disease. It may be an option for you if you have kidney impairment and either have or don't have type 2 diabetes.
San Ramon, CaliforniaAges 18 years+ - NCT05514184Enrolling by invitation
Diet coaching for diabetes and kidney disease to delay dialysis
This study tests a plant-focused diet plan to help people with diabetes and moderately to severely reduced kidney function avoid or delay needing dialysis. You would get diet instructions based on your random group and have several follow-up visits and check-ins over 6 months.
Torrance, CaliforniaAges 18 years+ - NCT04741646RecruitingPhase 2
Ferric citrate for kids with chronic kidney disease
This Phase 2 study tests ferric citrate, a medicine that helps control phosphate and iron balance, in children with chronic kidney disease. It may help slow problems related to kidney disease by improving lab measures like phosphate levels.

Finerenone plus blood-pressure medicine for kids with kidney disease
This Phase 3 study tests whether finerenone works and is safe in children with chronic kidney disease and significant protein in the urine, when taken with an ACE inhibitor or ARB. It also studies how the medicine moves through the body and its effects over time.
Palo Alto, CaliforniaAges 6 months–17 years - NCT05457283RecruitingPhase 3
Finerenone safety study for children with kidney disease
This trial studies how safely finerenone works over 18 months in children and young adults with chronic kidney disease who also take an ACE inhibitor or ARB. It aims to better understand long-term side effects when used together with standard kidney blood-pressure medicines.
Palo Alto, CaliforniaAges 1–18 - NCT07082738RecruitingPhase 2
Study of AZD6793 for people with moderate to very severe COPD

Web tool for birth control decisions with health conditions
This trial tests a web-based tool designed to help people with health conditions make informed choices about birth control. If you have a medical condition or take certain medications and want to discuss contraception with your doctor, this tool may help guide your conversation.
Pomona, CaliforniaAges 18–49 - NCT06907147Recruiting
Renal denervation for uncontrolled high blood pressure
This trial tests a procedure called renal denervation to lower blood pressure in people whose medication isn't enough. It uses a special catheter to calm nerves near the kidneys that may be overactive.
Stanford, CaliforniaAges 18–80 - NCT06283966RecruitingPhase 3
Triple inhaler for COPD with heart risk
This study tests a triple-combination inhaler (budesonide, glycopyrronium, and formoterol) to see if it can help protect the heart and lungs in people with COPD who also have heart problems or high risk for them.
Apple Valley, CaliforniaAges 40–80 - NCT06876363RecruitingPhase 1/Phase 2
Gene therapy study for X-linked chronic granulomatous disease
This study tests a new gene therapy called EN-374 for people with X-linked chronic granulomatous disease (X-CGD). It aims to fix the genetic cause of the disease to prevent severe infections and inflammation.
Los Angeles, CaliforniaAges 3 months+ - NCT06742723RecruitingPhase 3
Study of baxdrostat and dapagliflozin for kidney disease and high blood pressure
This trial tests if combining baxdrostat with dapagliflozin helps protect kidney function and reduce heart risks in people with chronic kidney disease and high blood pressure. It's for adults who are already taking standard blood pressure medications.
Beverly Hills, CaliforniaAges 18 years+ - NCT07107945RecruitingPhase 3
Study of empagliflozin for children with chronic kidney disease
This trial tests if empagliflozin, a daily pill, is safe and helps children ages 2–17 with chronic kidney disease (CKD). Your child may be eligible if they have reduced kidney function and elevated protein in their urine, and are already on stable kidney treatments.
Los Angeles, CaliforniaAges 2–17 - NCT03633708RecruitingPhase 3
Etelcalcetide for children with dialysis-related overactive parathyroid hormone
This trial studies etelcalcetide in children who have chronic kidney disease and too much parathyroid hormone while on hemodialysis. It aims to safely lower the hormone levels and help manage related bone/mineral problems.
Los Angeles, CaliforniaAges birth–18 years - NCT06712654RecruitingPhase 2

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 93 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.
