Clinical Trial Summary

Glioma is the most common primary malignant Brain Tumor. Although the traditional treatment (surgery, radiotherapy and chemotherapy) has been actively carried out, the curative effect of High grade glioma (HGG) is still poor.On the basis of a lot of exploration, the union medication has become a hot spot. Malignant glioma has obvious neovascularization and inhibiting angiogenesis can inhibit tumor proliferation and invasion.Studies have found that inhibiting VEGFR-2 can can reduce neovascularization and inhibit tumor growth. NCCN clinical practice guidelines recommend bevacizumab(BEV) for the treatment of recurrent malignant gliomas. AVAglio＆RTOG 0825 subgroup analysis showed that TMZ combined with antiangiogenic drugs may have advantages in the first-line treatment of patients with IDH1 wild-type high grade glioma.However, some studies have shown that bevacizumab can lead to rapid deterioration due to hypoxia or phenotypic changes. So it is urgent to find new antiangiogenic drugs. Apatinib is an oral small molecule antiangiogenic targeted drug. Apatinib plus temozolomide has been shown to be effective and tolerable in recurrent glioma. So the investigators aimed to evaluate the efficacy and safety of temozolomide combined with apatinib in the new diagnosis of high-grade glioma，and to explore the new first-line treatment of HGG, especially to TMZ insensitivity patients(MGMT gene promoter unmethylated) and poor prognosis (IDH1 wild type) population. And Find out the benefit groups of the two drugs.

Description:

Glioma is the most common primary malignant Brain Tumor.High grade glioma (HGG) has the characteristics of high morbidity, high relapse and high incidence of causing disability.Despite the progress in the combined treatment of surgery, radiotherapy and chemotherapy, the 2-year survival rate and 2-year non-progression survival rate were only 27.2% and 11.2%, respectively.

TMZ is the standard first-line chemotherapy, which can prolong the overall survival time and the progression-free survival time. Although TMZ has achieved satisfactory therapeutic effect since its application, the overall response rate of TMZ alone is still low which related to the methylation level of MGMT promoter.

On the basis of a lot of exploration, the union medication has become a hot spot. Malignant glioma has obvious neovascularization and inhibiting angiogenesis can inhibit tumor proliferation and invasion.

In recent years, antiangiogenic drugs have become a new treatment for malignant glioma. In recent years, studies have found that inhibiting VEGFR-2 can improve the sensitivity of glioma to TMZ chemotherapy. NCCN clinical practice guidelines recommend bevacizumab(BEV) for the treatment of recurrent malignant gliomas. Numerous clinical trials have studied the role of bevacizumab on glioma, and proved that bevacizumab can effectively prolong PFS without significant benefit to OS. AVAglio＆RTOG 0825 subgroup analysis showed that TMZ combined with antiangiogenic drugs may have advantages in the first-line treatment of patients with IDH1 wild-type high grade glioma.

However, some studies have shown that bevacizumab can lead to rapid deterioration due to hypoxia or phenotypic changes. So it is urgent to find new antiangiogenic drugs. Apatinib is an oral small molecule antiangiogenic targeted drug developed in China. As a specific vegfr-2 receptor inhibitor, apatinib plus temozolomide has been shown to be effective and tolerable in patients with recurrent glioma, but high-level evidence is still lacking. So the investigators conducted this clinical trial aimed to explore the new first-line treatment of high-grade glioma. The combination of TMZ and apatinib may have synergistic effect especially to TMZ insensitivity patients(MGMT gene promoter unmethylated) and poor prognosis (IDH1 wild type) population, as the high-level evidence is imminent.

From the perspective of molecular mechanism, A large number of studies have shown that vascular microenvironment closely related to glioma stem cell-like cells (GSLCs) and GSLCs can stimulate the proliferation by releasing VEGF to promote angiogenesis.. There was a correlation between the expression of vegfr-2 and CD133, a molecular biomarker of cancer stem cells. Therefore, CD133 may be an indirect target for the treatment of apatinib, and the therapeutic effect of apatinib may be related to the expression of CD133, not only vegfr-2. Monitoring the expression of CD133 can reflect the content of glioma stem cells on the one hand and indirectly reflect the therapeutic effect of vegfr-2 blocker apatinib on the other hand.
