A Study to Test the Addition of the Drug Cabozantinib to Chemotherapy in Patients With Newly Diagnosed Osteosarcoma

September 4, 2026 updated by: National Cancer Institute (NCI)

A Feasibility and Randomized Phase 2/3 Study of the VEGFR2/MET Inhibitor Cabozantinib in Combination With Cytotoxic Chemotherapy for Newly Diagnosed Osteosarcoma

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.

Study Overview

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the feasibility of adding cabozantinib S-malate (cabozantinib) to standard MAP (high dose methotrexate, doxorubicin hydrochloride [doxorubicin], and cisplatin) chemotherapy in patients with newly diagnosed metastatic osteosarcoma with a resectable primary tumor.

II. To determine whether MAP chemotherapy plus cabozantinib results in more favorable event-free survival (EFS) than MAP chemotherapy alone in patients with localized, resectable osteosarcoma.

III. To determine whether MAP chemotherapy plus cabozantinib results in more favorable event-free survival (EFS) than MAP chemotherapy alone in patients with metastatic, pelvic and unresectable osteosarcoma.

SECONDARY OBJECTIVES:

I. To determine whether MAP chemotherapy plus cabozantinib results in more favorable overall survival (OS) than MAP chemotherapy alone in patients with localized, resectable osteosarcoma.

II. To determine whether MAP chemotherapy plus cabozantinib results in more favorable overall survival (OS) than MAP chemotherapy alone in patients with metastatic, pelvic and unresectable osteosarcoma.

III. To prospectively validate that elevated circulating tumor DNA (ctDNA) levels greater than or equal to 5% at the time of diagnosis are associated with increased risk of EFS-event in patients with localized, resectable osteosarcoma.

IV. To prospectively validate that elevated ctDNA levels greater than or equal to 5% at the time of diagnosis are associated with increased risk of EFS-event in patients with metastatic, pelvic and unresectable osteosarcoma.

V. To prospectively validate that elevated ctDNA levels greater than or equal to 3% after initiation of therapy and prior to definitive surgery are associated with increased risk of EFS-event in patients with localized, resectable osteosarcoma.

VI. To prospectively validate that elevated ctDNA levels greater than or equal to 3% after initiation of therapy and prior to definitive surgery are associated with increased risk of EFS-event in patients with metastatic, pelvic and unresectable osteosarcoma.

VII. To determine whether MAP chemotherapy plus cabozantinib results in increased symptom burden and decreased tolerability to patients as measured by patient reported therapy-specific acute toxicities (Patient-Reported Outcomes-Common Terminology Criteria for Adverse Events [PRO-CTCAE]).

EXPLORATORY OBJECTIVES:

I. To determine the rate of good histologic response (> 90%) of resected primary tumor specimens following neoadjuvant chemotherapy with MAP plus cabozantinib and compare with response rates for MAP chemotherapy alone.

II. To describe the toxicities of the addition of cabozantinib to MAP chemotherapy in patients with newly diagnosed osteosarcoma.

III. To compare the probability of Grade 3 or higher port site wound complications on the MAP plus cabozantinib regimen to that of MAP chemotherapy alone in patients with newly diagnosed osteosarcoma who received a port for the administration of chemotherapy.

IV. To describe frequency of application of local control methods (surgery, hypofractionated stereotactic body radiotherapy, or radiofrequency ablation) for extrapulmonary metastatic osteosarcoma.

V. To compare total cumulative delivered doses of MAP chemotherapy agents between standard and experimental arms across multiple phases of therapy.

VI. To assess the pharmacokinetics of cabozantinib when administered concomitantly with standard chemotherapy agents during feasibility.

VII. To collect pulmonary metastatic lesions, paired primary tumor tissue, and serial blood samples for tumor profiling, liquid biopsies, and future testing of correlative biology studies.

VIII. To determine whether ctDNA at diagnosis and early on-treatment, as a continuous measurement of ctDNA burden, is associated with an increased risk of EFS-event in patients with newly diagnosed osteosarcoma.

IX. To evaluate whether the magnitude of change in ctDNA levels from diagnosis to planned surgical procedure is associated with risk of EFS-event in patients with newly diagnosed osteosarcoma.

X. To determine whether ctDNA levels greater than or equal to 3% after planned surgical procedures are associated with increased risk of EFS-event.

XI. To describe the presence of specific copy-number alterations, including MYC amplifications, detected in ctDNA and matched diagnostic tumor samples in patients with newly diagnosed osteosarcoma and determine whether frequently occurring copy-number alterations are associated with increased risk of EFS-event.

XII. To determine whether ctDNA burden is predictive of response to the experimental therapy in patients with newly diagnosed osteosarcoma.

XIII. To prospectively compare the impact of combination therapy on symptom bother as measured by the Functional Assessment of Cancer Therapy-General Questionnaire (FACT-G) item GP5 in patients with osteosarcoma receiving MAP chemotherapy with or without cabozantinib, and to assess the relationship between symptom bother and number of patient-reported acute toxicities (as measured by the PRO-CTCAE).

OUTLINE: This is a dose-escalation study of cabozantinib (Feasibility Phase) followed by a randomized phase II/III study (Efficacy Phase).

FEASIBILITY PHASE (CLOSED TO ACCRUAL 05/09/2025): Patients receive cabozantinib orally (PO), methotrexate intravenously (IV), doxorubicin IV, and cisplatin IV for two 35-day "induction" cycles. Patients are then considered for appropriate local control. Then they receive "consolidation" with methotrexate IV, doxorubicin IV, and cisplatin IV for one 35-day cycle, followed by cabozantinib PO, methotrexate IV, doxorubicin IV, and cisplatin IV for one 35-day cycle, and cabozantinib PO, methotrexate IV, and doxorubicin IV for two 35-day cycles. Patients then receive cabozantinib PO for six 28-day "maintenance" cycles.

EFFICACY PHASE: Patients with standard risk osteosarcoma are randomized to Arm A or Arm B. Patients with high risk osteosarcoma are randomized to Arm C or Arm D.

ARM A: Standard risk patients receive methotrexate IV, doxorubicin IV, and cisplatin IV for two 35-day "induction" cycles, followed by appropriate local control. Patients then receive "consolidation" with methotrexate IV, doxorubicin IV, and cisplatin IV for two 35-day cycles and methotrexate IV and doxorubicin IV for two additional 35-day cycles.

ARM B: Standard risk patients receive cabozantinib PO, methotrexate IV, doxorubicin IV, and cisplatin IV for two 35-day "induction" cycles, followed by appropriate local control. Patients then receive one 35-day "consolidation" cycle with methotrexate IV, doxorubicin IV, and cisplatin IV, then a second 35-day "consolidation" cycle with cabozantinib PO, methotrexate IV, doxorubicin IV, and cisplatin IV, followed by two additional 35-day "consolidation" cycles with cabozantinib PO, methotrexate IV, and doxorubicin IV. Patients then receive cabozantinib PO for six 28-day "maintenance" cycles.

ARM C: High risk patients receive methotrexate IV, doxorubicin IV, and cisplatin IV for two 35-day "induction" cycles, followed by appropriate local control. Patients then receive "consolidation" with methotrexate IV, doxorubicin IV, and cisplatin IV for two 35-day cycles and methotrexate IV and doxorubicin IV for two additional 35-day cycles.

ARM D: High risk patients receive cabozantinib PO, methotrexate IV, doxorubicin IV, and cisplatin IV for two 35-day "induction" cycles, followed by appropriate local control. Patients then receive one 35-day "consolidation" cycle with methotrexate IV, doxorubicin IV, and cisplatin IV, then a second 35-day "consolidation" cycle with cabozantinib PO, methotrexate IV, doxorubicin IV, and cisplatin IV, followed by two additional 35-day "consolidation" cycles with cabozantinib PO, methotrexate IV, and doxorubicin IV. Patients then receive cabozantinib PO for six 28-day "maintenance" cycles.

All patients also undergo X-ray, computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET) or bone scintigraphy at diagnosis and additional time points throughout the trial. All patients also undergo collection of blood samples during screening and on study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

No older than 40 years (Child, Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients must be < 40 years of age at the time of enrollment.
  • Patients must have a body surface area of >= 0.8 m^2 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.

For this study, metastatic disease is defined as one or more of the following:

  • Lesions which are discontinuous from the primary tumor, are not regional lymph nodes, and do not share a bone or body cavity with the primary tumor. Skip lesions in the same bone as the primary tumor do not constitute metastatic disease. Skip lesions in an adjacent bone are considered bone metastases.
  • Lung metastases: defined as biopsy-proven metastasis or the presence of one or more pulmonary lesions >= 5 mm, OR multiple pulmonary lesions >= 3 mm or greater in size.
  • Bone metastases: Areas suspicious for bone metastasis based on fludeoxyglucose F-18 (18F-FDG)-positron emission tomography (PET) scan (or whole body technetium-99 bone scan if 18F-FDG-PET is unavailable at the treating institution) require confirmatory biopsy or supportive anatomic imaging of at least one suspicious site with either magnetic resonance imaging (MRI) or computed tomography (CT) (whole body 18F-FDG-PET/CT or 18F-FDG-PET/MR scans are acceptable).

    • Efficacy Phases (Phase 2/3) NOTE: as of Amendment #2B, the efficacy phase is open for enrollment.

Patients with both localized and metastatic disease are eligible for the efficacy phase, regardless of resectability. Patients will be enrolled to two separate cohorts:

  • Cohort 1 (Standard Risk): Patients with non-pelvic primary osteosarcoma deemed to be resectable at the time of diagnosis by the institutional multidisciplinary team, without evidence of metastatic lesions.
  • Cohort 2 (High-Risk): Patients with a primary pelvic tumor, a primary tumor designated as unresectable by the institutional multidisciplinary team, AND/OR radiographic evidence of metastatic lesions.

    • A serum creatinine based on age/sex as follows (within 7 days prior to enrollment unless otherwise indicated):
  • (Age: Maximum Serum Creatinine [mg/dL]; Sex)

    • 1 month to < 6 months: 0.4 (male); 0.4 (female)
    • 6 months to < 1 year: 0.5 (male); 0.5 (female)
    • 1 to < 2 years: 0.6 (male); 0.6 (female)
    • 2 to < 6 years: 0.8 (male); 0.8 (female)
    • 6 to < 10 years: 1 (male); 1 (female)
    • 10 to < 13 years: 1.2 (male); 1.2 (female)
    • 13 to < 16 years: 1.5 (male); 1.4 (female)
    • >= 16 years: 1.7 (male); 1.4 (female)
  • OR - a 24 hour urine creatinine clearance >= 70 mL/min/1.73 m^2
  • OR - a glomerular filtration rate (GFR) >= 70 mL/min/1.73 m^2. GFR must be performed using direct measurement with a nuclear blood sampling method OR direct small molecule clearance method (iothalamate or other molecule per institutional standard).

    • Note: Estimated GFR (eGFR) from serum creatinine, cystatin C or other estimates are not acceptable for determining eligibility.

      • Total bilirubin =< 1.5 x upper limit of normal (ULN) for age (within 7 days prior to enrollment unless otherwise indicated)
      • Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) =< 135 U/L (within 7 days prior to enrollment unless otherwise indicated)
  • Note: For the purpose of this study, the ULN for SGPT (ALT) has been set to the value of 45 U/L

    • No history of congenital prolonged corrected QT (QTc) syndrome, New York Heart Association (NYHA) Class III or IV congestive heart failure, unstable angina pectoris, serious cardiac arrhythmias
  • Shortening fraction of >= 27%, or
  • Ejection fraction of >= 50%
  • Corrected QT interval by Fridericia (QTcF) < 480 msec on electrocardiogram. Patients with Grade 1 prolonged QTc (450-480 msec) at time of study enrollment should have correctable causes of prolonged QTc addressed if possible (i.e., electrolytes, medications).

    • Peripheral absolute neutrophil count (ANC) >= 1000/uL (within 7 days prior to enrollment unless otherwise indicated)
    • Platelet count >= 100,000/uL (transfusion independent, defined as not receiving platelet transfusions within a 7-day period prior to enrollment) (within 7 days prior to enrollment unless otherwise indicated)
    • Hemoglobin >= 8.0 g/dL (within 7 days prior to enrollment unless otherwise indicated)
    • International normalized ratio (INR) =< 1.5 (within 7 days prior to enrollment unless otherwise indicated)
    • Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible as long as they are NOT receiving anti-retroviral agents that are strong inhibitors or inducers of CYP3A4, CYP2D6, and/or MRP2 transporter protein.
    • All patients and/or their parents or legal guardians must sign a written informed consent.
    • All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human studies must be met.

Experimental: Efficacy Phase Arm D (cabozantinib, MAP)
High risk patients receive cabozantinib PO, methotrexate IV, doxorubicin IV, and cisplatin IV for two 35-day "induction" cycles, followed by appropriate local control. Patients then receive one 35-day "consolidation" cycle with methotrexate IV, doxorubicin IV, and cisplatin IV, then a second 35-day "consolidation" cycle with cabozantinib PO, methotrexate IV, doxorubicin IV, and cisplatin IV, followed by two additional 35-day "consolidation" cycles with cabozantinib PO, methotrexate IV, and doxorubicin IV. Patients then receive cabozantinib PO for six 28-day "maintenance" cycles. Patients also undergo X-ray, CT, MRI, and PET or bone scintigraphy at diagnosis and additional time points throughout the trial. All patients also undergo collection of blood samples during screening and on study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Event-free survival (EFS) (Phase II)
Time Frame: From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
The randomization and analysis will be stratified according to risk group. An assessment of the reduction in risk for EFS-event at the designated landmark time will be used to determine whether the trial continues to part 3. If the study proceeds to part 3, patients enrolled to part 2 of the trial will contribute to the primary analyses for part 3 of the study. If the interim criterion for continuation is not obtained, accrual will be closed with the conclusion that cabozantinib does not reduce sufficiently the risk for EFS-event for patients with newly-diagnosed osteosarcoma.
From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
Occurrence of dose-limiting toxicity (Feasibility)
Time Frame: Baseline up to 6 weeks
Only patients with high risk osteosarcoma who have a primary tumor considered resectable at the time of enrollment will be enrolled to this part of the trial. If a feasible dose cannot be established, the study committee will consult with Children's Oncology Group leadership and National Cancer Institute Cancer Therapy Evaluation Program regarding possible modifications of the regimen and subsequent protocol amendment.
Baseline up to 6 weeks
EFS (Phase III)
Time Frame: From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
Will consist of two randomized phase 3 sub-studies ('Phase 3'). One will be conducted in standard risk patients and one will be conducted in high risk patients.
From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
Overall survival
Time Frame: From randomization until death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
The one-sided logrank test will be the primary statistical methodology for assessing the null statistical hypothesis. The assessment of the reduction in risk of EFS-event will be conducted in standard risk patients and high risk patients separately.
From randomization until death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in symptom burden and tolerability
Time Frame: Up to 5 years after completion of study treatment
Will determine whether methotrexate, doxorubicin, and cisplatin (MAP) chemotherapy plus cabozantinib results in increased symptom burden and decreased tolerability to patients as measured by patient reported therapy-specific acute toxicities (Patient-Reported Outcomes-Common Terminology Criteria for Adverse Events [PRO-CTCAE]).
Up to 5 years after completion of study treatment
EFS
Time Frame: From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
Will validate whether elevated circulating tumor deoxyribonucleic acid (ctDNA) levels greater than or equal to 5% at the time of diagnosis are associated with increased risk of EFS-event in patients with localized, resectable osteosarcoma.
From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
EFS
Time Frame: From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
Will validate whether elevated ctDNA levels greater than or equal to 5% at the time of diagnosis are associated with increased risk of EFS-event in patients with metastatic, pelvic and unresectable osteosarcoma.
From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
EFS
Time Frame: From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
Will validate whether elevated ctDNA levels greater than or equal to 3% after initiation of therapy and prior to definitive surgery are associated with increased risk of EFS-event in patients with localized, resectable osteosarcoma.
From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
EFS
Time Frame: From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment

From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
ctDNA burden
Time Frame: Up to 5 years after completion of study treatment
Will determine whether ctDNA burden is predictive of response to the experimental therapy in patients with newly diagnosed osteosarcoma.
Up to 5 years after completion of study treatment
Impact of combination therapy on symptom bother
Time Frame: Up to 5 years after completion of study treatment
Will prospectively compare the impact of combination therapy on symptom bother as measured by the Functional Assessment of Cancer Therapy-General Questionnaire item GP5 in patients with osteosarcoma receiving MAP chemotherapy with or without cabozantinib, and to assess the relationship between symptom bother and number of patient-reported acute toxicities (as measured by the PRO-CTCAE).
Up to 5 years after completion of study treatment
EFS
Time Frame: From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
Will determine whether ctDNA at diagnosis and early on-treatment, as a continuous measurement of ctDNA burden, is associated with an increased risk of EFS-event in patients with newly diagnosed osteosarcoma.
From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
EFS
Time Frame: From randomization until disease progression, relapse, diagnosis of a second malignant neoplasm, death or last contact, whichever occurs first, assessed up to 5 years after completion of study treatment
Will evaluate whether the magnitude of change in ctDNA levels from diagnosis to planned surgical procedure is associated with risk of EFS-event in patients with newly diagnosed osteosarcoma.
