About this trial

This phase II/III trial tests the safety, side effects, and best dose of the drug cabozantinib in combination with standard chemotherapy, and to compare the effect of adding cabozantinib to standard chemotherapy alone in treating patients with newly diagnosed osteosarcoma. Cabozantinib is in a class of medications called kinase inhibitors which block protein signals affecting new blood vessel formation and the ability to activate growth signaling pathways. This may help slow the growth of tumor cells. The drugs used in standard chemotherapy for this trial are methotrexate, doxorubicin, and cisplatin (MAP). Methotrexate stops cells from making DNA and may kill tumor cells. It is a type of antimetabolite. Doxorubicin is in a class of medications called anthracyclines. It works by slowing or stopping the growth of tumor cells in the body. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Adding cabozantinib to standard chemotherapy may work better in treating newly diagnosed osteosarcoma.

Eligibility criteria

Qualifiers

Patients must be < 40 years of age at the time of enrollment.

Patients must have a body surface area of >= 0.8 m² at the time of enrollment.

Patients must have histologic diagnosis (by institutional pathologist) of newly diagnosed high grade osteosarcoma. Primary tumors of all extremity and axial sites are eligible as long as diagnosis of high-grade osteosarcoma is established. Osteosarcoma as a second malignancy is eligible if no prior exposure to systemic chemotherapies.

Feasibility Phase (NOTE: as of Amendment #2B, the feasibility phase has been completed) Patients must have metastatic disease and a resectable primary tumor. Designation of a primary tumor as resectable will be determined at the time of diagnosis by the institutional multidisciplinary team.

Disqualifiers

Patients who have received previous systemic therapy for osteosarcoma or a prior oncologic diagnosis.

Patients who have central nervous system metastases.

Patients with central cavitating pulmonary lesions invading or encasing any major blood vessels in the lung.

Patients who are unable to swallow tablets. Tablets cannot be crushed or chewed.
