Filter by:The purpose is to evaluate the effectiveness and safety of Surufatinib in patients with osteosarcoma and soft tissue sarcoma after Standard chemotherapy therapy.
Use exosome microfluidic chips to establish a combination of exosome subgroup level (exosome barcode) markers for the early diagnosis of osteosarcoma lung recurrence, and establish the basis of microfluidic chip based exosome biomarker for monitoring the early therapeutic response of the second-line therapy for recurrent osteosarcoma.
The purpose of this study is to evaluate the safety and tolerability of surufatinib, thereby identifying the Maximum Tolerated Dose (MTD) and/or Recommended Phase 2 Dose (RP2D) of surufatinib administered in combination with gemcitabine in pediatric patients with recurrent or refractory solid tumors or lymphoma. The study will be conducted in 2 parts.
Observational retrospective cohort study using laboratory data of blood tests prior to surgical and chemotherapy treatment and other histologic, clinical, and instrumental data related to patient history from digitized medical records and analysis of the same as predictors of outcomes.
To assess the neurocognitive outcomes in patients treated with chemotherapy for a malignant bone tumor during childhood and adolescence and the factors associated with neurocognitive impairment and/or complaints
Longitudinal cohort study; measurements before start of systemic therapy and one year later.
Two cycles of neoadjuvant three-component chemotherapy according to the MAP prototoc: Doxorubicin 25 mg / m2 IV on days 1-3, Cisplatin 120 mg / m2 IV on day 1 against the background of hyperhydration. G-CSF support from 4 to 13 days. Methotrexate 12 g / m2 at 28 and 35 days IV with leucovorin 60 mg / m2 in the first 5 days after each administration of methotrexate. The interval between cycles is 42 days. The advantage of this regimen is to use the three-component chemotherapy regimen, which should increase the degree of tumor necrosis and increase the rate of tumor response to treatment, which will further improve the disease prognosis. Currently, the use of such treatment for adult patients (over 24 years old) is controversial. Since it is believed that the elimination of methotrexate in adult patients is more delayed than in patients under 24 years old, and can lead to serious adverse events (SAE). However, the use of modern standard methods of hemodialysis makes it possible to avoid SAE.
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 phase II trial studies the effect of atezolizumab and cabozantinib in treating adolescents and young adults with osteosarcoma that has come back (recurrent) or has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving atezolizumab and cabozantinib may help to control the osteosarcoma.
The purpose of this study is to learn whether it is safe to give HER2-CAR T cells in combination with an immune checkpoint inhibitor drug (pembrolizumab or nivolumab), to learn what the side effects are, and to see whether this therapy might help patients with sarcoma. Another goal of this study is to study the bacteria found in the stool of patients with sarcoma who are being treated with HER2 CAR T cells and immune checkpoint inhibitor drugs to see if the types of bacteria influence how well the treatment works. The investigators have found from previous research that they can put a new gene into T cells that will make them recognize cancer cells and kill them. They now want to see if they can put a new gene in these cells that will let the T cells recognize and kill sarcoma cells. The new gene that the investigators will put in makes an antibody specific for HER2 (Human Epidermal Growth Factor Receptor 2) that binds to sarcoma cells. In addition, it contains CD28, which stimulated T cells and make them last longer. After this new gene is put into the T cell, the T cell becomes known as a chimeric antigen receptor T cell or CAR T cell. In another clinical study using these CAR T cells targeting HER2 as well as other studies using CAR T cells, investigators found that giving chemotherapy before the T cell infusion can improve the effect the T cells can have. Giving chemotherapy before a T cell infusion is called lymphodepletion since the chemotherapy is specifically chosen to decrease the number of lymphocytes in the body. Decreasing the number of the patient's lymphocytes first should allow the infused T cells to expand in the body, and potentially kill cancer cells more effectively. The chemotherapy used for lymphodepletion is a combination of cyclophosphamide and fludarabine. After the patient receives the lymphodepletion chemotherapy and CAR T cells during treatment on the study, they will receive an antibody drug called an immune checkpoint inhibitor, pembrolizumab or nivolumab. Immune checkpoint inhibitors are drugs that remove the brakes on the immune system to allow it to act against cancer.
