Glioblastoma is the most common and highly malignant brain tumor in adults. New targeted therapeutic approaches are imperative. EGFRvIII has appealing targets using monoclonal antibodies. Thus, endeavors toward developing new mAbs therapies for GBM capable of targeting biomarker must prevail to improve patient’s prognosis. Here, we isolated characterized an anti-EGFRvIII vNAR from a non-immune freshwater stingray mixed library, termed R426. The R426 pEGFRvIII interaction was demonstrated by molecular docking dynamics, recognition vitro further confirmed cell immunofluorescence staining. Moreover, shown be effective cisplatin drug carrier U87-MG glioma line. cisplatin-coupled significant differences when compared free CDDP at 72 h.

Glioblastoma, the most common and aggressive primary brain tumor in adults, presents a formidable challenge due to its rapid progression, treatment resistance, poor survival outcomes. Standard care typically involves maximal safe surgical resection, followed by fractionated external beam radiation therapy concurrent temozolomide chemotherapy. Despite these interventions, median remains approximately 12–15 months, with five-year rate below 10%. Prognosis is influenced factors such as patient age, molecular characteristics, extent of resection. Patients IDH-mutant tumors or methylated MGMT promoters generally have improved survival, while recurrent glioblastoma associated only six therapies cases are often palliative. Innovative treatments, including TTFields, add incremental benefits, extending around 20.9 months for eligible patients.
