Active clinical trials for "Osteosarcoma"

This treatment study for relapsed high-risk neuroblastoma, Ewings sarcoma, osteogenic sarcoma, rhabdomyosarcoma or synovial sarcoma involves an autologous cancer testis (CT) antigen specific dendritic cell (DC) vaccine preceded by decitabine as a demethylating chemotherapy.

This randomized phase III trial studies flexible administration of filgrastim after combination chemotherapy to see how well it works compared to fixed administration of filgrastim in decreasing side effects of chemotherapy in younger patients with cancer. Cancer chemotherapy frequently results in neutropenia (low blood counts) when patients are susceptible to severe infections. A medicine called G-CSF (filgrastim) stimulates bone marrow and daily filgrastim shots are commonly used to shorten neutropenic periods and decrease infections after chemotherapy. Since filgrastim is customarily used on a fixed schedule starting early after chemotherapy and there are data that early doses may not be needed, this study tests new flexible schedule of filgrastim to optimize its use by reducing the number of painful shots, cost of treatment, and filgrastim side effects in children with cancer receiving chemotherapy.

This study proposes to treat patients with the combination of erlotinib and temozolomide. Patients with relapsed, recurrent, refractory, or high risk malignancies whose tumors possess a non-synonymous mutation in EGFR, ERBB2, or JAK2V617F (JAK2) will be eligible for the study. Very few phase 2 clinical trials have been performed in pediatrics using targeted agents in combination with conventional chemotherapy agents. Furthermore, since some combinations such as the combination of this study (erlotinib and temozolomide) have shown additive/synergistic effects in preclinical studies, therapy selecting for those patients who possess mutations targeted by the TKI of the study, may unveil activity that has not been previously observed. Thus, the investigators hope to determine whether the addition of additive/synergistic chemotherapy will increase efficacy of target agent and/or increase tumor susceptibility to targeted agent resulting in increased anti-tumor activity.

This is a dose finding study of a novel radiopharmaceutical agent, 153Sm-DOTMP. It will be studied alone and then in combination with external beam radiotherapy. The study design includes six cohorts, Levels 1-6. The first three cohorts of participants will receive 153Sm-DOTMP alone, and if this is determined to be safe, subsequent cohorts will receive the radiopharmaceutical followed by external beam radiotherapy.

Background: - Pazopanib, a drug that inhibits the growth of new blood vessels in tumors, was recently approved by the Food and Drug Administration to treat advanced kidney cancer in adults. Pazopanib has been used in only a small number of adults, and more research is needed on whether it is safe and effective to use in children. Researchers are interested in determining safe and effective treatment doses of pazopanib in children, and in other studies will examine which form of pazopanib treatment (tablet or liquid) is most effective and well tolerated. Objectives: To determine a safe and effective dose of pazopanib to treat solid tumors in children. To study the effects of pazopanib on blood cells, blood flow, and human development. Eligibility: - Children, adolescents, and young adults between 1 and 21 years of age who have been diagnosed with solid tumors that have not responded to treatment. Design: Eligible participants will be screened with a physical examination, blood and tumor samples, and imaging studies. Participants will receive pazopanib tablets for 28-day cycles of treatment. Pazopanib should be taken on an empty stomach, at least 1hour before or 2 hours after a meal. Participants may receive pazopanib for up to 24 cycles unless the tumor does not respond or participants develop serious side effects. Blood samples will be taken on days 1, 15, 22, and 27 of the first cycle of pazopanib, with additional samples taken every 8 weeks during subsequent cycles. An optional part of the study will collect additional blood samples at regular intervals for 24 hours after the first dose of pazopanib and at regular intervals after another dose during the second or third week of the first treatment cycle.

The purpose of this research study is to see if a high dose of ascorbate (Vitamin C), in combination with the chemotherapy drug gemcitabine, is safe and effective in adolescents with locally advanced unresectable or metastatic soft tissue and bone sarcomas

This is an open label, two-stratum, phase 2 clinical trial evaluating the efficacy of 9-ING-41 in combination with gemcitabine/docetaxel in patients ≥10 years of age with advanced sarcoma. 9-ING-41 in combination with gemcitabine and docetaxel will lead to sustained disease control and/or increase the rates of objective response in patients with unresectable or metastatic soft tissue and bone sarcomas.

Subjects with relapsed or refractory neuroblastoma and osteosarcoma will receive ex-vivo expanded and activated natural killer (NK) cells from a haploidentical donor in conjunction with the immunocytokine, hu14.18-IL2.

The purpose of this study is to determine the safety and immunological effects of a vaccine for people diagnosed with high risk neuroblastoma, osteogenic sarcoma, and rhabdomyosarcoma. It is hypothesized that this vaccine could reduce the incidence of relapse.

Results of previous study showed high objective response but short-term activity of anti-angiogenesis tyrosine kinase inhibitors in advanced osteosarcoma. Given the recent success of immunotherapies, combinations of antiangiogenics with immune checkpoint blockers have become an attractive strategy. The investigators had completed an prospective phase 2 trial of the combination of apatinib and camrelizumab on advanced osteosarcoma and showed prolonged progression-free survival for this combination. Famitinib is a novel tyrosine kinase inhibitor targeting VEGFR-2, -3 and FGFR-1, -2, -3, -4 with high affinity, which showed broad antitumor activity against a variety of xenograft models. A Study to Compare the Efficacy and Safety of Levatinib with or without Ifosfamide and Etoposide in Children, Adolescents and Young Adults With Relapsed and Refractory Osteosarcoma showed promising median PFS of 11.3 months. Thus we also try to investigate the combination efficacy of TKIs with chemotherapy in advanced osteosarcoma. This study aims to investigate the recommended phase 2 dose for pediatric use of famitinib in combination with camrelizumab and trys to explore the efficacy and safety for single drug famitinib, famitinib and camrelizumab and famitinib and ifosfamide in patients with inoperable high-grade osteosarcoma progressing after chemotherapy.
