Fight Osteosarcoma with a European, evolving research platform from diagnosis to relapse
A European platform trial in pediatric and young adult high-grade osteosarcoma will test Cabometyx as one treatment option while collecting tumor and blood samples to guide future strategies.

Higher methotrexate discharge after standard osteosarcoma chemo
In newly diagnosed osteosarcoma patients 22 or younger, this study tests whether they can go home earlier with higher methotrexate levels after standard HD-MTX-based chemotherapy.

Tegavivint plus gemcitabine for relapsed or refractory osteosarcoma
This trial tests whether adding tegavivint to gemcitabine is safe and can help people whose osteosarcoma has come back or not responded to prior treatment.
