Active clinical trials for "Osteosarcoma"

To study the effect of the timing of surgery on outcome of patients with nonmetastatic osteosarcoma of pelvis and sacrum.

Non-randomized, open, two-cohort, phase II, multicenter national clinical trial. 20 sites in Spain. Cohort 1 includes soft-tissue sarcoma and osteosarcoma (21 patients), while Cohort 2 includes chordoma patients only (19 patients). Palbociclib will be administered orally at a dose of 125 mg once a day for 21 consecutive days followed by 7 rest days to comprise a complete cycle of 28 days. Treatment will continue until disease progression, development of unacceptable toxicity, non-compliance, withdrawal of consent by the patient or investigator decision. The main goal is to determine progression-free survival rate (PFSR) according to RECIST 1.1 at 6 months.

The purpose of this study is to evaluate the safety and efficacy of nivolumab, or nivolumab in combination with azacitidine in participants with recurrent, resectable osteosarcoma

This phase I/II trial studies the side effects and best dose of hydroxychloroquine and how well it works when given together with gemcitabine and docetaxel in treating participants with osteosarcoma that has come back or does not respond to treatment. Drugs used in chemotherapy, such as gemcitabine, docetaxel, and hydroxychloroquine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

The objective of this study is to assess safety and efficacy of CAB-AXL-ADC in solid tumors

3CAR is being done to investigate an immunotherapy for patients with solid tumors. It is a Phase I clinical trial evaluating the use of autologous T cells genetically engineered to express B7-H3-CARs for patients ≤ 21 years old, with relapsed/refractory B7-H3+ solid tumors. This study will evaluate the safety and maximum tolerated dose of B7-H3-CAR T cells.The purpose of this study is to find the maximum (highest) dose of B7-H3-CAR T cells that are safe to give to patients with B7-H3-positive solid tumors. Primary objective To determine the safety of one intravenous infusion of autologous, B7-H3-CAR T cells in patients (≤ 21 years) with recurrent/refractory B7-H3+ solid tumors after lymphodepleting chemotherapy Secondary objective To evaluate the antitumor activity of B7-H3-CAR T cells Exploratory objectives To evaluate the tumor environment after treatment with B7-H3-CAR T cells To assess the immunophenotype, clonal structure and endogenous repertoire of B7-H3-CAR T cells and unmodified T cells To characterize the cytokine profile in the peripheral blood after treatment with B7-H3-CAR T cells

This phase I/II trial evaluates the best dose, side effects and possible benefit of CBL0137 in treating patients with solid tumors, including central nervous system (CNS) tumors or lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Drugs, such as CBL0137, block signals passed from one molecule to another inside a cell. Blocking these signals can affect many functions of the cell, including cell division and cell death, and may kill cancer cells.

The purpose of this trial is to investigate whether previously reported benefit of Tranexamic acid in pediatric orthopedic surgeries could be recapitulated in bone tumor surgeries or not through a double blinded randomized controlled trial done in children cancer hospital 57357.

This is a randomized, double-blinded, 2 arms study concerning patients with high-grade bone sarcoma (HGBS) without complete remission after standard treatment at diagnosis or first relapse. In the first arm, patients will be treated with regorafenib + best supportive care (BSC) for a maximum of 12 months as maintenance therapy after standard line therapy completion, whereas in the second arm, patients will be treated with placebo + BSC (standard of care). The comparison between this two arms will allow to determine whether or not regorafenib and BSC is efficient for disease control, in terms of Progression-Free Survival improvement.

This phase II trial investigates how well oleclumab and durvalumab work in treating patients with sarcoma that has come back (recurrent) or does not respond to treatment (refractory) or has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as oleclumab and durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
