Profile of nimotuzumab in the treatment of high-grade glioma.

ABSTRACT: High-grade gliomas (HGG) are extremely aggressive lesions and represent the most common primary malignant brain tumors without an effective therapy. Standard treatment for HGG usually includes surgery followed by radiotherapy and chemotherapy. However, the prognosis of patients with HGG remains dismal. We review the humanized epidermal growth factor receptor (EGFR) and the major EGFR target drugs in HGG treatments, focusing on the EGFR antibody nimotuzumab as a new therapeutic strategy in HGG. We found that nimotuzumab with or without radiotherapy, chemotherapy in newly diagnosed or recurrent HGG, such as glioblastoma multiforme (GBM), anaplastic astrocytomas (AA), and diffuse intrinsic pontine glioma (DIPG), might improve the response rate or the survival time. In conclusion, nimotuzumab is a very well-tolerated drug with acceptable toxicity, and it may have promising value in the combination treatment. As a result, multiple center randomized controlled Phase III clinical trials need to be conducted to confirm the efficacy and toxicity for nimotuzumab in HGG.

Project description:Pediatric high-grade glioma (HGG) is a type of malignancy that carries a poor prognosis. The genetic analysis of HGGs has previously identified useful mutations, the targeting of which has improved prognosis. Thus, further research into the more common mutations, such as H3 histone variants (HIST1H3B and H3F3A) and BRAF V600E, may be useful in identifying tumors with different prognoses, as the mutations are considered to drive two distinct oncogenic programs. The present study performed a retrospective analysis of pediatric HGGs. In total, 42 cases of HGG, including 32 cases (76.1%) of anaplastic astrocytoma and 10 cases (23.8%) of glioblastoma multiforme (GBM), were assessed. The median age of the patients was 7 years (range, 0-32 years). Mutations on histone H3, in particular the K27M and G34R mutations in the distinct variants HIST1H3B and H3F3A, in addition to the presence of the BRAF V600E mutation, were analyzed in 24 patients. The H3F3A K27M mutation was identified in 7 patients (29.1%), while the HIST1H3B K27M mutation was only observed in 1 patient with GBM. In addition, 5 patients harbored a BRAF V600E mutation (21%), while the H3F3A G34R mutation was not recorded in any of the patients. The overall survival of the wild-type patients at 20 months was 68% [confidence interval (CI): 38-85%] compared with 28% (CI: 0.4-60%) in patients with the H3F3A K27M mutation. These results suggested that patients with the H3F3A K27M mutation had a worse prognosis compared with wild-type patients (P=0.0045). Moreover, 3/5 patients with the BRAF V600E mutation had HGGs that were derived from a previous low-grade glioma (LGG; P=0.001). In conclusion, these results suggested that histone H3 mutations may help predict the outcome in patients with HGG. In addition, the BRAF V600E mutation was found to be associated with an increased risk of anaplastic progression. The novel data of the present study may help better define the clinical and radiological characteristics of glioma.
