Abstract

Both the amplification of the gene coding for wild-type (wt) epidermal growth factor receptor (EGFR) and the overexpression of the EGFR deletion mutant, commonly known as EGFRvIII, are hallmarks of glioblastoma. We have recently reported a novel, recombinant immunotoxin, D2C7-(scdsFv)-PE38KDEL, that targets both wt EGFR and EGFRvIII, exhibiting potent antineoplastic effects against established murine gliomas.

The research work in my laboratory focuses on identifying novel immunotherapeutic targets for the treatment of brain tumors, specifically glioblastoma (GBM). My previous work includes the development of the dual-specific immunotoxin (IT) D2C7-IT, which is currently in Phase I clinical trials in recurrent GBM (rGBM) patients. My current research seeks to identify novel strategies to enhance the efficacy of D2C7-IT and other GBM-targeted cytotoxic therapies. In conjunction with this, my research includes the investigation of immune-related biomarkers to predict the clinical outcome of D2C7-IT therapy in patients with GBM.
