AOST1421: This phase II trial is combining two biological therapies (Dinutuximab and Sagramostim) for the treatment of recurrent OsteosarcomaA Phase 2 Study of Human-Mouse Chimeric Anti-Disialoganglioside Monoclonal Antibody ch14.18 (Dinutuximab, NSC# 764038) in Combination With Sargramostim (GM-CSF) in Patients With Recurrent Osteosarcoma

Inclusion

• Patients must have histologic diagnosis of osteosarcoma at original diagnosis

• Patients must have had at least one episode of disease recurrence in the lungs without limitation on number of episodes of recurrence as long as they meet the following criteria:

  • Surgical resection of all possible sites of suspected pulmonary metastases in order to achieve a complete remission within 4 weeks prior to study enrollment**

  • Pathologic confirmation of metastases from at least one of the resected sites

    • For patients with bilateral pulmonary metastases, resection must be performed from both lungs and the study enrollment must be within 4 weeks from date of the last lung surgery
  • Note: If surgery related changes such as atelectasis are seen on the post-operative computed tomography (CT) scan, patients will remain eligible to enroll as long as the operating surgeon believes that all sites of metastases were resected; patients with positive microscopic margins will be eligible to enroll
• Patient must have adequate tumor specimen available for submission

• Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study

  • Myelosuppressive anti-cancer therapy: must not have been received within 2 weeks of study entry (4 weeks if prior nitrosourea)
  • Biologic (anti-neoplastic agent): at least 7 days since the completion of therapy with a biologic agent
  • Radiation therapy (RT): >= 2 weeks for local palliative radiation therapy (RT) (small port); >= 6 weeks must have elapsed if prior craniospinal RT or if >= 50% radiation of pelvis; >= 6 weeks must have elapsed if other substantial bone marrow (BM) radiation
  • Surgery: >= 2 weeks from last major surgery, including pulmonary metastasectomy, with the exclusion of a central line placement and core needle or small open biopsies
• Patient must not have received pegfilgrastim within 14 days of enrollment
• Patient must not have received filgrastim (G-CSF, Neupogen) within 7 days of enrollment

• Patient must not have received immune suppressants: corticosteroids (for other than allergic reactions and anaphylaxis), cyclosporine or tacrolimus within 7 days of enrollment

  • Note: the use of topical and/or inhalational steroids is allowed
• Total absolute phagocyte count (APC = [%neutrophils + %monocytes) x white blood cells [WBC]) is at least 1000/uL
• Platelet count >= 50,000/uL
• Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70 mL/min/1.73 m^2 or

• A serum creatinine based on age/gender as follows:

  • 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)
• Total bilirubin =< 1.5 x upper limit of normal (ULN) for age
• Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) =< 110 U/L (for the purpose of this study, the ULN for SGPT is 45 U/L)
• Serum albumin >= 2 g/dL
• Baseline electrocardiogram (EKG) shows normal corrected QT interval (QTc) interval of =< 470 milliseconds (ms)
• Shortening fraction of >= 27% by echocardiogram, or
• Ejection fraction of >= 50% by radionuclide angiogram or echocardiogram
• No evidence of dyspnea at rest, no history of exercise intolerance, and a pulse oximetry > 94%
• Patient has no known history of seizure disorder
• Central nervous system (CNS) toxicity including peripheral neuropathy =< grade 2
