Recruiting studies in California
- NCT04726241RecruitingPhase 1/Phase 2
Testing blood and bone marrow samples in young leukemia patients
This trial looks at blood and bone marrow samples from children and teens whose leukemia has come back or is hard to treat. The goal is to better understand the disease and guide future options for these patients.

Study medicine for agitation in youth with bipolar or schizophrenia
This Phase 1 trial tests whether BXCL501 is safe and can help reduce agitation in children and teens who have bipolar disorder or schizophrenia. You may be considered if your agitation is significant during screening, but certain recent medication and health factors can make you ineligible.
Anaheim, CaliforniaAges 10–17 - NCT05076175RecruitingPhase 2/Phase 3
Oral ozanimod for children with moderate to severe ulcerative colitis
This trial tests whether an oral medicine called ozanimod can improve ulcerative colitis (UC) in children whose disease is moderate to severe. It’s meant for kids who didn’t fully respond—or couldn’t tolerate—standard UC treatments.
Garden Grove, CaliforniaAges 2–17 - NCT05101551RecruitingPhase 1
Talazoparib with chemotherapy for relapsed childhood AML
This Phase 1 study tests whether talazoparib combined with chemotherapy is safe and potentially effective for children and young adults whose leukemia has come back or did not respond. It focuses on finding the best way to give the treatment and watching for side effects.

Butyrate treatment for kids with mild-to-moderate ulcerative colitis
This trial tests whether butyrate can help children and teens with mild-to-moderate ulcerative colitis (a long-term bowel inflammation condition). You may be able to join if your symptoms fit the study level and you haven’t recently started other specific ulcerative colitis treatments right before the study begins.
Los Angeles, CaliforniaAges 7–21 - NCT05224778Recruiting
Study for young children with neonatal myotonic dystrophy type 1
This study looks at measurements and child-focused outcomes in babies and toddlers with myotonic dystrophy type 1 (DM1) that started in the newborn period. It may help researchers better track how the condition affects children and evaluate care plans more accurately.
Los Angeles, CaliforniaAges Up to 4.9 years - NCT05294302Recruiting
Online support program for cancer parents in English or Spanish
This trial tests an online (e-health) counseling and support program for parents of children with cancer. It may help you feel better supported and more informed while caring for your child.
Los Angeles, CaliforniaAges Any age - NCT05303064RecruitingPhase 3
Study of weight gain medicine for teens with certain mood or psychosis
This Phase 3 study tests a treatment aimed at reducing unhealthy weight gain in teens with schizophrenia or bipolar I disorder, using changes in BMI (a height-and-weight measure). It may help families who are concerned about weight changes that can happen with some psychiatric medicines.
Upland, CaliforniaAges 10–17 - NCT05371613RecruitingPhase 2/Phase 3
Testing tividenofusp alfa vs idursulfase for MPS II
This trial compares a new treatment (tividenofusp alfa) to the current standard treatment (idursulfase) in children and young adults with MPS II. It’s looking to see which option works better and is safe, especially based on age and whether the disease affects the brain.
Oakland, CaliforniaAges 2–25 - NCT05372640RecruitingPhase 1
Drug combo trial for rare cancers with shared NUT features
This Phase 1 trial tests the safety and early signs of effectiveness of combining two anti-cancer drugs (ZEN003694 and abemaciclib) in teens and adults with metastatic or unresectable NUT carcinoma, breast cancer, and other solid tumors. It may help by finding a safer dose and whether the drug combination can shrink or control tumors that do not respond to standard treatments.
Los Angeles, CaliforniaAges 12 years+ - NCT05457140Recruiting
Testing genes and other samples in youth with first psychosis
This study looks at many types of tests (including genetic testing and other lab data) to help understand what may be causing first-time psychosis symptoms in youth. It may help doctors learn more about the condition for future care, and it can involve analyzing family genetic information.
San Diego, CaliforniaAges 7–17 - NCT05471232Recruiting
Genomic testing for youth mental health crises with IDD

San Diego, CaliforniaAges 7–17 - NCT05476770RecruitingPhase 1
Tagraxofusp for children with CD123-positive leukemia
This study tests tagraxofusp, a medicine that targets a marker called CD123 on cancer cells, in children and young adults whose leukemia or lymphoma has come back or is resistant to treatment. It may help by shrinking the cancer and improving disease control after standard therapies have not worked.
Orange, CaliforniaAges 1–21 - NCT05491525RecruitingPhase 2/Phase 3
Vibegron for children with nerve bladder using intermittent catheter
This study tests how well and how safely vibegron works long-term in children (ages 2 to under 18) with a nerve-related bladder condition, who regularly use intermittent catheterization. It also tracks how the body processes the medicine and whether it helps bladder control over time.

What taking part in a pediatrics 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.
Pediatrics trials in other states
Common questions
- Are there pediatrics clinical trials in California?
- Yes. We're currently tracking 189 recruiting pediatrics 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 pediatrics 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 pediatrics 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 pediatrics 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.
