What was measured

Objective: To study the feasibility of combining: 1) bevacizumab with cisplatin, doxorubicin, and high-dose methotrexate (MAP) in patients with localized resectable osteosarcoma; and 2) bevacizumab with MAP and ifosfamide, and etoposide in patients with unresectable or metastatic osteosarcoma. The target unacceptable toxicity is defined as grade 4 hypertension, proteinuria, or bleeding excluding petechiae/purpura, grade 3/4 thrombosis/embolism excluding catheter-related thrombosis. The unacceptable toxicity for major wound complication is defined as grade 2, 3, or 4 major wound complications. A six-stage group sequential stopping rule was developed for monitoring unacceptable toxicity.

Analysis population: Due to slow accrual, the trial was closed to accrual early. Thus, only 31 stratum A patients and 12 stratum B or C patients were enrolled on the study. Therefore, based on the number of patients enrolled and the designed power for the study, we do not have confidence in making a conclusion regarding this feasibility objective.

Groups in this outcome

A: Localized Resectable Disease

Stratum A participants had primary tumors potentially resectable by aggressive surgery, such as limb-salvage surgery or amputation, and no evidence of metastasis.

C: Metastatic Tumors

Stratum C participants had metastatic tumors.
