Participants will receive cabozantinib and BSC.

Participants will receive BSC alone administered per investigator's discretion and institutional guidelines.

Participants will receive cabozantinib orally Once daily (QD) on a continuous dosing schedule for cycles of 28 days.

Cabozantinib

Participants will receive BSC. BSC includes antibiotics, nutritional support, correction of metabolic disorders, optimal symptom control and pain management (including palliative radiotherapy), etc. but does not include tumor specific therapy.

Best Supportive Care (BSC)

Participants will receive BSC alone. BSC includes antibiotics, nutritional support, correction of metabolic disorders, optimal symptom control and pain management (including palliative radiotherapy), etc. but does not include tumor specific therapy.

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.

Effects of Maintenance Cabozantinib+BSC Versus BSC in Children and AYA With Osteosarcoma

A Phase II, Randomized, Open-label Study to Assess the Efficacy, Safety, and Pharmacokinetics (PK) of Maintenance Cabozantinib (XL184) Plus Best Supportive Care (BSC) Versus BSC in Children, Adolescents and Young Adults (AYA) With Unresectable Residual Osteosarcoma Either at Diagnosis or at First Relapse After Standard Treatment

Qualified researchers may request access to patient level data and related study documents including the clinical study report, study protocol with any amendments, annotated case report form, statistical analysis plan, and dataset specifications.

Patient level data will be anonymized and study documents will be redacted to protect the privacy of study participants.

Any requests should be submitted to www.vivli.org for assessment by an independent scientific review board.

PFS defined as the time from the date of randomization to the date of first documented disease progression or the date of death due to any cause, whichever occurs first.

PFS rate at 4 months and 1 year was defined as the probability that participants have not progressed by BIRC assessment and remain alive at 4 months and 1 year.

ORR defined as the proportion of participants who have achieved complete response (CR) or partial response (PR) determined by BIRC.

Defined as the proportion of participants who have achieved CR, PR, or stable disease (SD) determined by BIRC

Defined as the time from the date of randomization to the date of first documented disease progression determined by investigator or the date of death due to any cause, whichever occurs first

Defined as the probability that participants have not progressed by investigator assessment and remain alive at 4 months and 1 year.

Defined as the proportion of participants who have achieved complete response (CR) or partial response (PR) determined by investigator using RECIST version 1.1.

Defined as the proportion of participants who have achieved CR, PR, or SD determined by investigator.

Defined as the time from date of randomization to the date of death, from any cause

Defined as the probability participants alive at 1 year.

An Adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. AESIs are AEs that may not be serious but are of special importance to a particular drug or class of drugs.

Five-point Facial Hedonic Scale (FHS) with a correlated 100-point horizontal Visual Analog Scale (VAS) (FHS/VAS-5) will be used to assess acceptability and palatability in children and adolescents. Final scores range from 0 to 100, with higher scores indicating better palatability and acceptability.

The PedsQL is a modular instrument designed to measure health-related quality of life in children and adolescent. The PedsQL generic core scales are multidimensional child self-report and parent proxy-report scales developed as the generic core measure to be integrated with the PedsQL. The PedsQL cancer modules was designed to measure paediatric cancer specific HRQoL. Final total scores range from 0 to 100, with higher scores indicating better health related quality of life.

The EORTC QLQ-C30 was developed by the EORTC Quality of Life Group to assess HRQoL, functioning, and symptoms in cancer clinical trials. It is a 30-item self-administered questionnaire for all cancer types. Final scores range from 0 to 100, with higher scores indicating better health related quality of life. A high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status / QoL represents a high QoL, but a high score for a symptom scale / item represents a high level of symptomatology / problems.
