A study of ExPD-101 for COPD with chronic bronchitis and frequent flare-ups
This study tests an experimental drug (ExPD-101) given daily as a pill for 52 weeks for people with COPD who have chronic bronchitis and frequent flare-ups. It compares the drug to a placebo (inactive pill) to see if it reduces flare-ups and improves symptoms.
Northridge, CaliforniaAges 40–85 - NCT04722835Recruiting
Study lung immune cells in people at risk for COPD
This study looks at different lung immune cell patterns and how they work in smokers who are not yet diagnosed with COPD or asthma. It may help researchers understand why some people are more likely to develop COPD, which could guide future prevention or early treatments.
San Francisco, CaliforniaAges 40–75 - NCT04918095Recruiting
COPD home monitoring with a phone or tablet
This study tests a home monitoring program for people with COPD (a long-term lung condition) to track symptoms using a phone or tablet. It may help clinicians spot changes earlier and improve how COPD care is managed.
Ventura, CaliforniaAges 40–100 - NCT05237505RecruitingPhase 2
Sleep apnea plus COPD study to check heart and breathing effects
This Phase 2 study looks at the cardiovascular (heart/blood vessel) effects of having both sleep apnea and COPD. It may help doctors better understand who is at risk and how to manage these breathing problems together.
La Jolla, CaliforniaAges 40–79 - NCT05572632Recruiting
COPD wellness rehab program for safety-net patients

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.
