Study Description
This study is for children, teens, and young adults who have a type of bone cancer called osteosarcoma. Osteosarcoma is rare but is the most common bone cancer in young people. It happens when cancer cells make immature bone. The study includes participants whose cancer couldn’t be completely removed with surgery and who have shown some improvement or stable disease after regular chemotherapy.
In the study, participants will either:
- Take a medication called cabozantinib (a daily tablet) along with supportive care, or
- Receive supportive care only, which can include treatments like antibiotics, nutritional support, pain management, and other care but not cancer-specific therapy.
If the cancer worsens for those receiving only supportive care, they might switch to also taking cabozantinib if they meet certain conditions. Cabozantinib will continue as long as it is helping and well-tolerated. The study is expected to last about 24 months for each participant, but they may stay in the study longer if they are benefiting from the treatment. Participants can choose to leave the study at any time.
Inclusion Criteria
- Participants must be ≥5 and ≤30 years old
