San Francisco, CaliforniaAges 18–65 - NCT07059091RecruitingPhase 2
Allergy medicine for COPD with indoor allergies
This study tests if omalizumab, an allergy medicine, can help people with COPD who are allergic to common indoor allergens and have had recent flare-ups. It aims to see if reducing allergic reactions can improve COPD control.
San Francisco, CaliforniaAges 40 years+ - NCT07040319RecruitingPhase 1/Phase 2
Hepatitis C treatment study for pregnant women
This study tests a medicine called glecaprevir/pibrentasvir for pregnant women with hepatitis C, with or without HIV. It aims to see how the medicine works in the body and if it is safe during pregnancy.
Los Angeles, CaliforniaAges 16–45 - 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+ - NCT06918990RecruitingPhase 1
CarBel for antibody-mediated rejection after kidney transplant
This study tests a new drug called CarBel to treat antibody-mediated rejection in kidney transplant patients. The goal is to see if it can help stop the rejection and protect your new kidney.
Los Angeles, CaliforniaAges 18–75 - 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 - NCT06832189RecruitingPhase 1
Testing everolimus and epoetin for liver transplant tolerance
This trial is testing whether a combination of two drugs, everolimus and epoetin, can help liver transplant recipients gradually reduce their anti-rejection medicines. If successful, it may lead to long-term transplant tolerance with fewer side effects.
San Francisco, CaliforniaAges 18 years+ - 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 - 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 - NCT06583395Enrolling by invitation

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?
