Active clinical trials for "Osteosarcoma"

The purpose of this study is to determine whether nivolumab plus ipilimumab are effective and safe in the treatment of sarcoma and endometrial carcinoma patients with somatic deficient MMR as a selection tool.

Apatinib second line treatment for Advanced osteosarcoma and soft tissue sarcomas ,openting ,single center, one-armed clinical study.

This is a Phase 1+2, open-label, dose-escalation, and multidose study, aiming to investigate the safety, tolerability and pharmacokinetics of ZKAB001 (a fully human monoclonal antibody targeting the Programmed Death - Ligand 1 (PD-L1) membrane receptor on T lymphocytes and other cells of the immune system) administered every 14 days in subjects with limited stage of high-grade osteosarcoma of maintenance therapy after adjuvant chemotherapy.

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.

At present, the most effective drugs to osteosarcoma include ADM,DDP,,HD-MTX,IFO and so on.The effective rate of single drug was about 30%, and if the chemotherapy contains HD-MTX, the survival rate can reach about 60%, so the HD-MTX is the most important component in patients of osteosarcoma. Studies have shown that, MTX efficacy and adverse reactions were associated with blood concentration level and duration, selecting the right time and dose to give CF is the critical point.

Preclinical models show that a daily antiangiogenic regimen at low-dose may be effective against chemotherapy-resistant tumors. The aim of this study is to evaluate the efficacy of maintenance therapy with continuous oral cyclophosphamide and methotrexate in patients with high grade, operable, metastatic osteosarcoma (OST) of the extremities. The primary end point is event-free survival (EFS) from randomization

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.

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.

Preclinical models show that a daily antiangiogenic regimen at low-dose may be effective against chemotherapy-resistant tumors. The aim of this study is to evaluate the efficacy of maintenance therapy with continuous oral cyclophosphamide and methotrexate in patients with high grade, operable, non-metastatic osteosarcoma (OST) of the extremities. The primary end point is event-free survival (EFS) from randomization.

This an an open-label study to define the safety profile and the maximum tolerated dose and confirm the clinical effective dose of palifosfamide-tris given intravenously in combination with etoposide and carboplatin in a wide range of cancers which etoposide and carboplatin are normally given. Once the maximum dose of palifosfamide-tris is determined,a Phase II study using the 3 agents combined will begin.
