Brief Summary:
Preclinical models show that a daily antiangiogenic regimen at low-dose may be effective against chemotherapy-resistant tumors. The aim of this study is to evaluate the efficacy of maintenance therapy with continuous oral cyclophosphamide and methotrexate in patients with high grade, operable, metastatic osteosarcoma (OST) of the extremities. The primary end point is event-free survival (EFS) from randomization

Condition or disease Intervention/treatment Phase
Osteosarcoma Drug: Cyclophosphamide Drug: Methotrexate Phase 2

Detailed Description:
The study design includes backbone of 10 weeks of preoperative therapy using MAP (high-dose methotrexate, cisplatin, doxorubicin and dexrazoxane). Metastatic patients were randomized to high-dose chemotherapy for 31 weeks (arm 1) or concomitant metronomic therapy (MTX plus cyclophosphamide) such as 31 weeks of high-dose chemotherapy, followed by 73 weeks of metronomic therapy after completion of high-dose chemotherapy, totaling 104 weeks of metronomic therapy (arm 2).

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Efficacy and toxicity of adding metronomic therapy in disease event-free survival. [ Time Frame: Five years ]
    To assess the impact of adding metronome therapy to the standard treatment of patients with resectable end-stage osteosarcoma and metastatic lung disease in event-free survival.


Secondary Outcome Measures :
  1. Efficacy and toxicity of adding metronomic therapy in overall survival [ Time Frame: Five years ]
    To evaluate the impact of the addition of metronomic therapy to the standard treatment of patients with end-resectable osteosarcoma and metastatic lung disease in overall survival.

  2. Cardiotoxicity (occurrence of cardiotoxicity) [ Time Frame: Five years ]
    To compare the occurrence of cardiotoxicity with the addition of dexrazoxane since the first cycle of doxorubicin with the findings of the previous study (GLATO 2006).

  3. Immunohistochemistry (expression of VEGF) [ Time Frame: Five years ]
    Immunohistochemistry the expression of VEGF in the biopsy, primary tumor and metastases

  • Patients with normal organic function
  • Sexually active participant should agree to use contraceptive methods throughout the treatment
  • Female participant should have a negative pregnancy test

Exclusion Criteria:

  • If the participant or their legal guardian refuses to sign the informed consent form / consent term it will not be included in the study.
