Filter by:This study is being done in order to evaluate the effectiveness of using two drugs (olaparib and ceralasertib) to treat patients with osteosarcoma that has not responded to treatment or has come back after treatment The names of the study drugs involved in this study are: - Olaparib - Ceralasertib
Post-authorization, observational, multicenter and prospective study in patients between 2 and 30 years old diagnosed with non-metastatic high-grade osteosarcoma of the extremities. All patients included in the study will receive the initial neoadjuvant treatment prescribed by the doctor of each center, according to standard practice (involving methotrexate, cisplatin, and adriamycin). This initial treatment precedes surgical treatment. After surgical treatment, the histological response to neoadjuvant chemotherapy will be evaluated. The histological response to primary chemotherapy will be expressed as a percentage of tumor necrosis. In the case of tumor necrosis above 90% the patient is defined as a "good responder" in case of a lower percentage as a "poor responder". As an adjuvant treatment, the following options may be given according to standard practice in each center: 1. - If there is overexpression of ABCB1 / P-glycoprotein and poor response to induction treatment, in many sites ifosfamide at high doses and MTP-PE, is incorporated in addition to adriamycin. 2. - If there is overexpression of ABCB1 / P-glycoprotein and a good response to induction treatment, in many centers the option of additional administration of methotrexate, CDDP and adriamycin will be chosen. 3. - If there is no overexpression of ABCB1 / P-glycoprotein, the administration of methotrexate, adriamycin and cisplatin will be chosen in many sites. In some sites they will consider the non-administration of MTP-PE or the non-administration of high doses of ifosfamide. And, in some hospitals, they will consider administering MTP-PE to all patients.
The purpose of this research is to evaluate the study drug, 18F FTC-146, as a positron emission tomography (PET) / computed tomography (CT) radiotracer imaging agent to evaluate tumor status in patients newly diagnosed with osteosarcoma ("bone cancer").
It is a randomized, double-blind, placebo-controlled, multicenter study with the sample size is 362. The patients with high-grade osteosarcoma who had previously received surgery and completed adjuvant chemotherapy will be randomly assigned to ZKAB001 group (trial group) or placebo group (control group) according to 1:1. The purpose is to evaluate the efficacy and safety of ZKAB001 in maintenance therapy after adjuvant chemotherapy in patients with high-grade osteosarcoma.
Treatment strategies for high-grade osteosarcoma with multidrug chemotherapy and resection result in 3-year event-free survival of 60-70%. The most common factors predicting survival are presence of metastases, histological response to preoperative chemotherapy and complete surgical resection. Four of the active drugs in osteosarcoma include cisplatin, doxorubicin, high-dose methotrexate and ifosfamide and this combination (MAPI), given preoperatively and postoperatively, is widely used for the treatment of osteosarcoma in China. Apatinib also has activity in advanced setting and when incorporated into the treatment of patients with metastatic disease seemed to improve progression-free survival. Combination of apatinib and camrelizumab resulted in durable therapuetic effect in selected cases. Though EURAMOUS-1 suggested that changing chemotherapy postoperatively on the basis of histological response did not improve outcomes. The exploratory study with radomised design to compare combination of chemotherapy with target drug or combination of chemotherapy with anti-PD-1 antibody versus standard chemotherapy has not been tried yet. Thus we aim to investigate the efficacy and toxicity of these combiantions versus standard chemotherapy in this study.
This phase II pediatric MATCH treatment trial studies how well selpercatinib works in treating patients with solid tumors that may have spread from where they first started to nearby tissue, lymph nodes, or distant parts of the body (advanced), lymphomas, or histiocytic disorders that have activating RET gene alterations. Selpercatinib may block the growth of cancer cells that have specific genetic changes in an important signaling pathway (called the RET pathway) and may reduce tumor size.
Osteosarcoma is the most common primary highly malignant bone tumor in children and young people. Incidence rates are bimodal, with the first peak occurring in adolescence and the second peak in patients over 60 years of age. The 5-year survival rate of patients with osteosarcoma is less than 20%. This study aims to improve the prognosis of patients and change the outcome of patients with osteosarcoma.
Osteosarcoma is the most common primary malignant bone tumor that mainly occurs in children and adolescents. Combined surgical resection and intensive chemotherapy has improved the 5-year overall survival rate (from 51 to 75%). However, drug-induced side effects and tumor recurrence after surgery reduce patient quality of life and cut down the patient survival rate. Superparamagnetic Iron Oxide Nanoparticles (SPIONs)/Spinning Magnetic Field (SMF) and neoadjuvant chemotherapy may increase the cancer cell killing and complete tumor shrinkage preserving local structures and functions of patients who cannot receive limb retention treatment.
This study is a open-lable, , single center, phase II clinical study. Target population is patients with locally resectable osteosarcoma. Study objective is to compare the efficacy and safety of camrelizumab in combination with adriamycin, cisplatin, ifosfamide and methotrexate in study population in China. Camrelizumab is a humanized anti-PD1 IgG4 monoclonal antibody.
This phase II pediatric MATCH trial studies how well tipifarnib works in treating patients with solid tumors that have recurred or spread to other places in the body (advanced), lymphoma, or histiocytic disorders, that have a genetic alteration in the gene HRAS. Tipifarnib may block the growth of cancer cells that have specific genetic changes in a gene called HRAS and may reduce tumor size.
