Recruiting studies in California
- NCT06960213RecruitingPhase 3
Study of ADX-324 for preventing HAE attacks
This study tests a new medicine called ADX-324 to see if it can prevent HAE attacks in adults with type I or II HAE. If you've had attacks recently and are willing to pause your current prevention medication, this trial may be an option.
Walnut Creek, CaliforniaAges 18 years+ - NCT07428499RecruitingPhase 3
Long-term safety of ADX-324 for hereditary angioedema
This study is for people who already finished a previous trial of the drug ADX-324 for hereditary angioedema. It tests the long-term safety and effectiveness of continuing the medication.
San Diego, CaliforniaAges 18 years+ - NCT05396105Enrolling by invitationPhase 2/Phase 3
Oral PHA-022121 extension for hereditary angioedema attacks
This study is an extension trial of an oral medicine (PHA-022121) for treating acute attacks in people with hereditary angioedema (HAE), especially HAE type III (HAE-nC1INH). It checks whether continuing this oral treatment can safely help manage attacks after you’ve taken it before.
San Diego, CaliforniaAges 12 years+ - NCT06679881RecruitingPhase 3
Preventing swelling attacks with oral deucrictibant for HAE
This study tests a long-term daily pill to prevent swelling attacks in people with hereditary angioedema (HAE). The pill, called deucrictibant, is designed to block a protein involved in causing attacks. It's for adolescents and adults who want to reduce how often swelling episodes occur.
Walnut Creek, CaliforniaAges 12 years+ - NCT07179601Recruiting
Embolization for hemorrhoid symptoms study
This trial tests if blocking certain blood vessels in the rectum can reduce bleeding and other symptoms from hemorrhoids. If you have bothersome internal hemorrhoids that haven't been helped by other treatments or if surgery is not an option for you, this study may be a fit.
Los Angeles, CaliforniaAges 18–90 - NCT07298447RecruitingPhase 3
Donidalorsen for children with hereditary angioedema
This study tests a new medicine, donidalorsen, to prevent swelling attacks in children ages 2 to 11 with hereditary angioedema (HAE). If your child has HAE type 1 or 2, this trial may help find a treatment option.
Santa Monica, CaliforniaAges 2–11 - NCT07204938Enrolling by invitationPhase 3
Long-term study of navenibart for hereditary angioedema
This study tests navenibart over a longer period to see if it continues to prevent swelling attacks in people with hereditary angioedema. It is for people who were already in a previous navenibart study.
San Diego, CaliforniaAges 12 years+ - NCT07559630Recruiting
Artery Blocking vs Rubber Bands for Internal Hemorrhoids
This trial compares two treatment methods for internal hemorrhoids that haven't improved with diet, fiber, or creams. One method blocks blood flow to the hemorrhoids using a catheter (a thin tube); the other uses rubber bands to cut off blood supply. Both are minimally invasive procedures.

What taking part in a hae 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 hae clinical trials in California?
- Yes. We're currently tracking 8 recruiting hae 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 hae 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 hae 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.
