We’re tracking 17 recruiting osteosarcoma studies with a site in California — including Early Phase 1, Phase 1, Phase 1/Phase 2 and Phase 3 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT04616560RecruitingPhase 1/Phase 2
New drug for recurrent Wilms tumor, osteosarcoma, and DSRCT
This trial tests a targeted drug called trastuzumab deruxtecan for children and young adults with certain cancers that have come back or not responded to treatment. It may help if your tumor has not responded to standard therapies.
Los Angeles, CaliforniaAges 12–39 - NCT05235165RecruitingPhase 3
Surgery choice for lung spread of osteosarcoma
This Phase 3 trial compares two ways to remove lung metastases (open surgery vs keyhole surgery) in people with osteosarcoma. It aims to see which approach works better and is safer for patients with a limited number of lung spots that can be removed.
Anaheim, CaliforniaAges Up to 50 years - NCT03900793RecruitingPhase 1
Losartan plus sunitinib for osteosarcoma after prior treatment
This early-phase study tests whether adding losartan to sunitinib can help control osteosarcoma that has returned or keeps growing after at least one prior treatment. It may help by targeting the cancer’s growth signals and blood supply, but the goal at this stage is mainly to check safety and find workable dosing.
Los Angeles, CaliforniaAges 10 years+ - NCT04851119RecruitingPhase 1/Phase 2
Tegavivint for kids and young adults with hard-to-treat solid tumors
This early-phase study tests tegavivint to see how well it works and how safe it is for children and young adults with solid cancers that have come back or are not responding. It may be an option if your tumor type (including certain lymphomas or desmoid tumors) matches the study’s rules.
Los Angeles, CaliforniaAges 1–30 - NCT04901702RecruitingPhase 1/Phase 2
Onivyde plus talazoparib or temozolomide for resistant solid tumors
This trial tests whether adding Onivyde to either talazoparib or temozolomide can shrink or control hard-to-treat (refractory or recurring) cancers in children and young adults. It aims to find safer dosing first, then look at how well the treatment works—especially for Ewing sarcoma.
Palo Alto, CaliforniaAges 1–30 - NCT06064682Recruiting
Organoid test to guide osteosarcoma treatment
This trial uses a lab-grown mini tumor (organoid) from your biopsy to test which drugs might work best for your osteosarcoma. It aims to personalize your treatment based on how your specific cancer cells respond.
Los Angeles, CaliforniaAges Any age - NCT07357519RecruitingPhase 1/Phase 2
Targeted radiation therapy for advanced osteosarcoma
This trial tests a new targeted radiation treatment (177Lu-TARGETed Osteosarcoma Therapy) for people with advanced osteosarcoma that has not responded to or has come back after prior chemotherapy. The goal is to see if this treatment can help shrink or control the cancer.
Los Angeles, CaliforniaAges 12 years+ - NCT05227326RecruitingPhase 1
A new drug for solid cancers that did not respond to usual care
This early-stage (Phase 1) trial tests AOH1996 in adults with solid tumors that have stopped responding to standard treatments. It’s meant to find a safe dose and see if the drug can help, especially in cancers with limited options.
Duarte, CaliforniaAges 18 years+ - NCT03458520Recruiting
Kid PET/MR scan registry for solid tumor imaging
This study is a registry that collects images from children (and some adults) with suspected or confirmed solid tumors to help researchers learn how best to use PET/MR scans. It may help future patients by improving imaging and diagnosis planning.
Palo Alto, CaliforniaAges Up to 40 years - NCT04282044RecruitingPhase 1
CRX100 drug trial for advanced cancers with or without pembrolizumab
This Phase 1 trial tests CRX100 (a new cancer medicine) alone and with pembrolizumab (an immune checkpoint drug) in people with advanced solid tumors. It’s mainly designed to check safety and side effects, and to see whether tumors respond, potentially helping people whose cancer has come back or stopped responding to standard treatment.
Stanford, CaliforniaAges 18 years+ - NCT05642455RecruitingPhase 1/Phase 2
Study of a new treatment for certain childhood cancers
This Phase 1/2 study tests a new therapy for children and young adults with specific types of cancer that have been treated with chemotherapy before. It may help by targeting cancer features in the tumor and using your immune system in a controlled way.
Palo Alto, CaliforniaAges 2–21 - NCT06156410RecruitingPhase 1
Cabozantinib and ifosfamide for relapsed sarcomas
This study tests a combination of two drugs, cabozantinib and ifosfamide, for sarcomas that have come back or not responded to treatment. The goal is to see if this combination can help shrink or control the cancer.
San Francisco, CaliforniaAges 5–40 - NCT06387485Recruiting
3D printed models for surgery planning
This study tests whether using a 3D printed model of your tumor helps surgeons plan operations better than standard scans. It might improve outcomes for people with bone-invasive tumors that need to be removed.
Oakland, CaliforniaAges 13 years+ - NCT06500819RecruitingPhase 1
B7-H3 CAR T cells for relapsed solid tumors
This trial tests a new immune therapy using your own cells (called B7-H3 CAR T cells) to treat solid tumors that haven't responded to other treatments. It may help children and young adults with certain cancers that are hard to cure.
Palo Alto, CaliforniaAges 2–30 - NCT06541262RecruitingPhase 1/Phase 2
Silmitasertib plus chemo for relapsed solid tumors
This trial tests a new drug, silmitasertib, combined with standard chemotherapy for children and young adults with cancers that have come back or not responded to treatment. The goal is to see if this combination can shrink tumors or stop them from growing.
San Diego, CaliforniaAges Up to 30 years - NCT01790152Recruiting
Dexrazoxane study to monitor heart damage in cancer survivors
This study tests dexrazoxane (DRZ) to see how it affects blood and heart-related “biomarkers,” or measurable signs of heart damage, after cancer treatment. It mainly targets survivors who may be at risk for cardiomyopathy (heart muscle weakness) or related heart failure.
Palo Alto, CaliforniaAges Any age - NCT07628634RecruitingEarly Phase 1
Testing a Low-Methionine Diet in Solid Tumor Patients
This early-stage study explores whether eating a diet low in methionine (a natural amino acid found in protein) might help people with advanced solid tumors. Researchers will track how this dietary change affects blood levels and may improve treatment outcomes alongside standard cancer care.
Orange, CaliforniaAges 18 years+

What taking part in a osteosarcoma 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 osteosarcoma clinical trials in California?
- Yes. We're currently tracking 17 recruiting osteosarcoma 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 osteosarcoma 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 osteosarcoma 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 osteosarcoma 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.
