Plain-language summary
The participants of this study will be children, adolescents, and young adults with residual osteosarcoma, which cannot be removed completely through surgery.
Participants will have achieved a partial response or stable disease at the end of conventional chemotherapy. Osteosarcoma is cancer of the bone. The cancer cells make immature bone cells, known as osteoid.
Osteosarcoma is very rare, but it is the most common type of bone cancer in children and teens. It is most common in teens and young adults.
In this study, participants will receive either cabozantinib and best supportive care or the best supportive care alone. Best supportive care will be provided at the investigator's discretion and according to institutional guidelines.
It includes antibiotics, nutritional support, correction of metabolic disorders, optimal symptom control and pain management (including radiotherapy), etc. but does not include tumor specific therapy.
Cabozantinib will be taken by mouth (orally), as a tablet, once a day. Cabozantinib will be provided to participants who tolerate it for as long as their disease does not progress. Participants in the study receiving best supportive care alone may switch to treatment with cabozantinib and best supportive care if their disease progresses and if other eligibility criteria are met.
Participants may withdraw consent to participate at any time.
The estimated duration of the study for participants is 24 months, however a participant could remain in the study longer if demonstrating treatment benefit.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria :
* Participants must be ≥5 and ≤30 years of age at the time of study entry.
* Histologically or cytologically confirmed diagnosis of high-grade osteosarcoma as defined by a local pathologist
* Participants with unresectable residual disease after standard chemotherapy treatment at diagnosis or first relapse (treated with systemic chemotherapy). A minimum of 4 cycles of systemic chemotherapy (or minimum of 2 cycles if chemotherapy was stopped early due to toxicity) must have been received.
* Measurable residual or evaluable disease by RECIST version 1.1. Participants will be considered with evaluable disease if they have only non-measurable disease as per RECIST version 1.1 criteria.
* Absence of Progressive Disease (PD) (defined by the investigator according to RECIST version 1.1) at study entry. Note, the two most recent radiological evaluations (e.g. computerised tomography (CT) or magnetic resonance resonance imaging (MRI) scan) including the one following completion of chemotherapy should be available later to facilitate BIRC review.
* Chemotherapy must be the last anticancer treatment received by participants before study entry and must have been completed at least 4 weeks but no longer than 2 months before randomization.
* Participants must have recovered to Grade ≤1, except for alopecia, ototoxicity, and Grade ≤2 peripheral neuropathy, per Common Terminology Criteria for Adverse Events (CTCAE) version 5.0) from the acute toxic effects of all prior …
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

Progression-free Survival (PFS) assessed by Blinded Independent Radiology Committee (BIRC)
Timeframe: From randomization until disease progression or death from any cause, whichever occurs first (approximately 34 months).
