Recruiting studies in California
- NCT06975865RecruitingPhase 3
Rilzabrutinib for sickle-cell disease pain episodes
This study tests an oral medicine called rilzabrutinib to see if it can reduce painful episodes in people with sickle-cell disease. It may be an option if you have regular pain crises and are looking for a new treatment.
Clovis, CaliforniaAges 10–65 - NCT07369024RecruitingPhase 2
Study of low-dose ketamine for sickle cell pain crisis
This study tests whether a low-dose of ketamine (a pain medicine) can help children and young adults with sickle cell disease who are in a pain crisis. It aims to provide better pain relief while avoiding some side effects of standard painkillers.
Torrance, CaliforniaAges 5–20 - NCT07224360RecruitingPhase 2
Safety of a new drug for sickle cell pain
This study tests a new medicine called anumigilimab to see if it is safe for people with sickle cell disease. The study focuses on those who have had pain crises recently, to help manage and prevent them.
Orange, CaliforniaAges 18 years+ - NCT07187973RecruitingPhase 1
Study of DISC-3405 for people with sickle cell disease
This trial tests an investigational drug called DISC-3405 in people with sickle cell disease (SCD) to see if it is safe and how it affects your body. It may be an option if you have certain SCD complications or lab results.
San Francisco, CaliforniaAges 18 years+ - NCT06385886Recruiting
Study to improve sickle cell care for adults not seeing a specialist
This study helps connect adults with sickle cell disease who haven't seen a specialist in over a year back into care. It tests a program designed to make it easier to get regular medical support and improve your health.

CSL889 for sickle cell pain crisis
This trial tests a new medicine, CSL889, for people with sickle cell disease who are currently having a pain crisis (vaso-occlusive crisis). The goal is to see if it safely helps reduce the pain and speed recovery.
Oakland, CaliforniaAges 12 years+ - NCT06609226RecruitingPhase 3
Long-term safety study of etavopivat for sickle cell disease or thalassaemia
This study looks at the long-term safety and benefits of taking etavopivat for people with sickle cell disease or thalassaemia who have already been helped by it in a previous trial. It aims to see if staying on the treatment continues to be safe and effective.
Los Angeles, CaliforniaAges 2 years+ - NCT06612268RecruitingPhase 3
Etavopivat for reducing sickle cell pain crises
This study tests an investigational oral pill called etavopivat that may help reduce pain crises in people with sickle cell disease. You may qualify if you have frequent pain crises and are not on regular blood transfusions.
Orange, CaliforniaAges 12 years+ - NCT06481306RecruitingPhase 1/Phase 2
Testing a new drug for sickle cell disease in healthy people and patients
This early-phase study tests a new drug (BMS-986470) for people with sickle cell disease who have frequent pain crises. The goal is to see if it can safely reduce crises. It includes a small group of healthy volunteers as well.
La Jolla, CaliforniaAges 18 years+ - NCT06439082RecruitingPhase 3
Crizanlizumab for sickle cell pain crises
This trial tests whether crizanlizumab can reduce painful sickle cell crises (called vaso-occlusive crises or VOCs) in people with sickle cell disease who have frequent crises. It may be an option for those who still have crises despite current treatments.
Orange, CaliforniaAges 12–100 - NCT06363760Enrolling by invitation
Long-term follow-up after EDIT-301 gene therapy

Oakland, CaliforniaAges 12–50 - NCT06374238Recruiting
Peer support for young people with sickle cell pain
This study tests whether having a peer mentor who also has sickle cell disease can help young people manage chronic pain. You would use a mobile app to connect with your mentor and track your pain.
Los Angeles, CaliforniaAges 16–39 - NCT06260891RecruitingPhase 2
Zinc study for sickle cell disease and bone health
This study tests if taking zinc supplements can improve bone health in people with sickle cell disease. It's for those with certain types of sickle cell disease (SS or S-Beta zero thalassemia) who are not on chronic transfusions or zinc supplements.
Oakland, CaliforniaAges 15–40 - NCT06016634RecruitingPhase 2

This trial tests if the drug alendronate can help heal bone damage caused by sickle cell disease. It may be an option if you have this bone problem and are between 18 and 80 years old.
Sacramento, CaliforniaAges 18–80 - NCT04774536RecruitingPhase 1/Phase 2
CRISPR gene-edited bone marrow transplant for severe sickle cell
This Phase 1/2 study tests a CRISPR-edited bone marrow (stem cell) transplant to treat severe sickle cell disease. It aims to reduce dangerous sickle-related complications by changing the patient’s stem cells before transplant.
Oakland, CaliforniaAges 12–35 - NCT04819841RecruitingPhase 1/Phase 2
Gene correction using your own stem cells to improve sickle disease
This trial tests a gene-correction treatment that changes sickle hemoglobin (HbS) into normal hemoglobin (HbA) using your own stem cells. It may help reduce severe sickle cell complications for people with severe disease who meet specific safety and medical criteria.
Palo Alto, CaliforniaAges 12–50 - NCT04628585Enrolling by invitation
Follow-up for people with sickle cell treated with gene therapy
This study is a long-term follow-up for people who already received gene therapy for sickle cell disease in a specific sponsor’s clinical trial. It helps researchers watch for long-term safety and outcomes over time.

It may help high-risk patients who have frequent complications and don’t have a fully matched donor.
Duarte, CaliforniaAges 1–30 - NCT02675959RecruitingPhase 2
Transplant with defibrotide for sickle cell disease
This trial tests a stem cell transplant from a half-matched donor using a strong conditioning regimen and a drug called defibrotide to protect organs. It aims to cure sickle cell disease in patients who have had serious complications like stroke, chest syndrome, or frequent pain episodes.

Long-term follow-up study for sickle cell disease treatment
This study is a follow-up for people with sickle cell disease who already saw a benefit in fetal hemoglobin from the earlier Pioneer study. It tests the long-term safety and effects of the study drug pociredir (also called FTX-6058) while allowing most standard sickle cell treatments except hydroxyurea.

What taking part in a sickle cell 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 sickle cell disease clinical trials in California?
- Yes. We're currently tracking 26 recruiting sickle cell 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 sickle cell 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 sickle cell 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 sickle cell 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.
