Recruiting studies
- NCT07211737RecruitingPhase 1
C7R-GD2 CAR-T cells for osteosarcoma or neuroblastoma
This trial tests a new treatment using your own immune cells (called C7R-GD2 CAR-T cells) that are trained to find and kill cancer cells. It's for children and young adults with osteosarcoma or neuroblastoma that has not gotten better with standard treatments.
Houston, TexasAges 1–24 - NCT05400603RecruitingPhase 1
Immunotherapy trial for relapsed neuroblastoma or osteosarcoma
This Phase 1 study tests lab-made donor immune cells (gamma delta T cells) plus chemotherapy to treat neuroblastoma or osteosarcoma that has come back or hasn’t responded to standard treatment. It’s designed to find a safe way to give this treatment and to see how well it might work.
Atlanta, GeorgiaAges 1 year+ - NCT07144254RecruitingPhase 1
Tegavivint and gemcitabine for relapsed osteosarcoma
This trial tests a new drug called tegavivint combined with the chemotherapy drug gemcitabine for people whose osteosarcoma has come back or stopped responding to treatment. The goal is to see if this combination can help shrink or control the cancer.
Atlanta, GeorgiaAges 1–30 - NCT06492954RecruitingPhase 1
Testing atezolizumab with radiation and surgery for lung-only osteosarcoma
This trial tests whether combining an immunotherapy drug (atezolizumab) with focused radiation and surgery can help people whose osteosarcoma has come back only in the lungs. It aims to see if this approach is safe and may improve outcomes.
Atlanta, GeorgiaAges Up to 50 years - 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+ - NCT06017518Recruiting
Watching local relapse after high-grade osteosarcoma treatment
This study is watching people whose high-grade osteosarcoma came back in the same bone area (local relapse) after treatment. It helps doctors understand how local relapse happens, so they can improve future care.
Bologna, BOAges Any age - NCT05830123RecruitingPhase 2
Test drug HS-20093 for osteosarcoma after earlier treatment
This Phase 2 trial studies HS-20093 in adults with osteosarcoma or other sarcomas that came back or did not respond to standard treatment. It aims to see how well the drug works and whether it is safe for people whose cancer has progressed.
BeijingAges 18 years+ - NCT07725380RecruitingPhase 1/Phase 2
Two drugs for relapsed sarcoma or osteosarcoma
This trial studies a new combination of two drugs, domatinostat and sirolimus, for people with sarcoma or osteosarcoma that hasn't improved after standard treatments. The goal is to see if this combination can help shrink or slow the cancer.
Tampa, FloridaAges 12–40 - NCT04758000RecruitingPhase 2
Metformin after bone cancer treatment to prevent relapse
This Phase 2 study tests whether taking metformin after surgery and chemotherapy can reduce the risk of bone cancer coming back in people at high risk of relapse. You may be eligible if you have osteosarcoma or Ewing sarcoma that is not currently spread and you meet specific lab and health criteria.
BolognaAges 14 years+ - 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.
Birmingham, AlabamaAges Up to 30 years - NCT06709495RecruitingPhase 1/Phase 2
PEEL-224 with chemo for teens and young adults with sarcoma
This trial tests a new drug called PEEL-224 combined with two chemotherapy drugs (vincristine and temozolomide) for people ages 12 to 49 with sarcoma that has come back or hasn't responded to standard treatments. The goal is to see if this combination is safe and effective.
Boston, MassachusettsAges 12–49 - NCT06607692RecruitingPhase 1/Phase 2
LuPARPed: Targeted radiation plus olaparib for certain childhood cancers
This trial tests a combination of a radioactive drug (Lutathera) and a targeted pill (olaparib) for children and teens whose solid tumors have come back or not responded to treatment and show high levels of a specific receptor (SSTR) on scans. The goal is to see if this two-drug approach can shrink tumors or stop them from growing.

Common questions
- Are there clinical trials for relapsed osteosarcoma?
- Yes. Clin2 currently lists 12 recruiting relapsed osteosarcoma studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a relapsed osteosarcoma trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a relapsed osteosarcoma trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
