Active clinical trials for "Osteosarcoma"

This study is looking to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of lyso-thermosensitive liposomal doxorubicin (LTLD) administered in combination with MR-HIFU in children with relapsed/refractory solid tumors, which may include but are not limited to rhabdomyosarcoma and other soft tissue sarcomas, Ewing's sarcoma family of tumors, osteosarcoma, neuroblastoma, Wilms' tumor, hepatic tumors, and germ cell tumors.

This is a pilot study that will allow investigators to collect data related to early and potentially more accurate response assessments using a chemotherapy protocol that eliminates methotrexate to maximize the dose intensity of doxorubicin. The pilot data will be used to seek funding to more fully address the hypotheses in a multi-institutional, Phase II or Phase III trial. The primary and secondary objectives are as follows: Primary: To evaluate the feasibility and potential usefulness of measuring early changes in tumor metabolic activity, assessed by Fludeoxyglucose-Positron Emission Tomography (FDG-PET) imaging and alkaline phosphatase activity, as early predictors of histological response rate at 12 weeks in osteosarcoma patients. To explore whether histological response can be assessed by a computer algorithm using virtual microscopic images of pathology material, and whether quantifying necrosis in this way correlates with microscope slide-based review. Secondary: 1. To gather pilot data on the histological response rate, 3-year event-free survival, and toxicity when children and young adults with resectable osteosarcoma are treated using a chemotherapy regimen of alternating courses of doxorubicin/cisplatin (DC) and doxorubicin/ifosfamide/etoposide (IDE). All patients will receive 4 courses of preoperative chemotherapy courses. With the exception of high-dose methotrexate, which is given weekly, preoperative and postoperative chemotherapy courses are planned to begin every 21 days. Patients with good histological response (those patients with > 90% tumor necrosis at time of definitive resection) will receive three postoperative chemotherapy courses. The 1st will consist of doxorubicin, dexrazoxane, cisplatin and Granulocyte-Colony Stimulating Factor (G-CSF)(or Polyethylene Glycol filgrastim). The 2nd course will consist of doxorubicin, dexrazoxane, ifosfamide, MESNA, etoposide, G-CSF (or PEG-filgrastim). The 3rd course will consist of ifosfamide, MESNA, etoposide, G-CSF (or PEG-filgrastrim). The total doxorubicin dose will be 450 mg/m2. Patients with poor response (those patients with < 90% tumor necrosis found on pathology at time of definitive resection) will receive five postoperative chemotherapy courses. High Dose-Methotrexate will be administered during the 1st and 3rd postoperative chemotherapy courses as 4-weekly and 2-weekly doses, respectively. The 2nd course will consist of doxorubicin, dexrazoxane, cisplatin and G-CSF (or PEG-filgrastim). The 4th course will consist of doxorubicin, dexrazoxane, ifosfamide, Mesna, etoposide, G-CSF (or PEG-filgrastim). The 5th cycle will consist of ifosfamide, Mesna, etoposide, G-CSF (or PEG-filgrastrim). The total doxorubicin dose will be 450 mg/m2.

The aim of the study is to describe, through a minimum follow-up of 18 months, the quality of life of patients undergoing salvage surgery of lower limb for musculoskeletal tumors and to identify possible prognostic factor correlated. Quality of life will be evaluated with Bt-DUX (Bt=bone tumor)

The purpose of this study is to evaluate the feasibility of a multimodal prehabilitation intervention intended to optimize postoperative recovery in adolescents and young adults (AYAs) diagnosed with soft tissue and bone-based sarcomas of the upper and lower extremities (extremity sarcomas; ES).

The purpose of this study is to examine if we can predict sensitivity of osteosarcoma to different chemotherapy agents using tissue cultures in the laboratory. We know that different chemotherapy agents can be used in the treatment, but not every sarcoma responds to them equally. It is important to understand if testing of the tissue obtained during a routine biopsy or surgery may be useful in selecting appropriate treatments. In addition, additional testing of the tumor, including genetic testing, will help us to understand osteosarcoma better.

After standard multimodal therapy, the prognosis of relapsed and unresectable high-grade osteosarcoma is dismal and unchanged over the last decades.Thus, the investigators explored apatinib activity in patients with relapsed and unresectable osteosarcoma after the failure of first-line or second-line chemotherapy. Patients >16 years, progressing after standard treatment, were eligible to receive 500 mg or 750 mg of apatinib once daily until progression or unacceptable toxicity. The primary end point was progression-free survival (PFS) at 4 months and objective response rate (ORR). Secondary objectives were PFS, overall survival (OS), clinical benefit rate (CBR), defined as no progression at 6 months and safety.

This phase II trial studies how well dinutuximab works when given with sargramostim in treating patients with osteosarcoma that has come back after treatment (recurrent). Monoclonal antibodies, such as dinutuximab, may find tumor cells and help kill them. Sargramostim may help the body increase the amount of white blood cells it produces, which help the body fight off infections. Giving dinutuximab with sargramostim may work better and kill more cancer cells.

This clinical trial seeks to determine if avelumab will be effective in facilitating removal of all gross tumor in the event of a relapse of osteosarcoma in pediatric patients. Avelumab will be evaluated using dosing that has previously been determined in adult studies. Primary Objectives: To estimate the response rate to 4 cycles of avelumab in patients with recurrent or progressive osteosarcoma. To estimate the 16-week progression free survival of patients with recurrent or progressive osteosarcoma after treatment with avelumab. Secondary Objective: To describe the toxicities associated with the administration of avelumab in patients with recurrent or progressive osteosarcoma. To assess the quality of life of patients with recurrent or progressive osteosarcoma undergoing treatment with avelumab, and to explore relationships between clinical factors and patient-reported health-related quality of life (HRQOL) outcomes. Exploratory Objectives: To explore factors associated with response in patients treated with avelumab after recurrent or progressive osteosarcoma (e.g. tumor PD-L1 expression). To measure parameters of immune activation including subsets of peripheral blood mononuclear cells (PBMCs) and serum markers of immune activation. To evaluate the role of T-cells in immune checkpoint blockade via measures of cell proliferation, co-inhibitory receptor expression on CD8 T cells, T cell repertoire, and epigenetic programming.

This research study is a clinical trial of a new combination of drugs as a possible treatment for relapsed/refractory Ewing sarcoma and/or osteosarcoma. The names of the drugs are: Cabozantinib Topotecan Cyclophosphamide The names of the non-investigational supportive care drugs are: Filgrastim, pegfilgrastim, or a related growth factor.

The purpose of this study is to determine the safest and most effective oral dose combinations of sorafenib and irinotecan in pediatric patients with solid tumors, i.e. relapsed or refractory.
